PREFACE

PREFACE Louisville Gas and Electric Company (LG&E) provides retail gas and electric service in a defined service territory in and around the Metro Louisville, Kentucky area. The Customer Gas Piping Handbook is intended to address natural gas service issues within the prescribed service territory. A separate document, “Electric Service Handbook”, details the requirements for electric service. Customer Gas Piping Handbook The Customer Gas Piping Handbook prescribes LG&E’s standards with respect to gas service and meter installations pursuant to the rules and regulations of the Kentucky Public Service Commission (KPSC). All piping used for gas service lines and meter installations must be installed in accordance with the specifications provided by LG&E and will be subject to inspection and testing by LG&E. In the event that special circumstances prevent compliance with the service line specifications prescribed within this handbook, LG&E will give proper consideration to alternative methods, provided that the above-referenced regulations are not violated and that safety and reliability are not jeopardized. The Customer has the responsibility of notifying LG&E of any changes to the piping, appliances, or building structure that may affect safety or gas system performance. In addition, this handbook includes standards pertaining to Customers’ house piping and appliance installation in the interest of uniform and safe operations. The standards for new house piping and appliance installation are generally applicable for replacement or relocation of existing facilities. By publishing this handbook, LG&E does not assume liability or responsibility for house piping, appliance installation, or appliance operation. LG&E maintains the right to refuse to supply gas to piping or appliances that are installed or operated in a potentially unsafe manner. In addition, LG&E is not responsible for continuing inspection or surveillance of Customers’ house piping, appliances, or appliance operation. LG&E reserves the right to modify the requirements found in this handbook or any of its service policies, procedures and/or standards at any time. It is the responsibility of the Customer to ensure that any reference document is the version currently approved for use by LG&E. It is also the responsibility of the Customer to notify LG&E of any changes to natural gas facilities that may affect the safety or natural gas system performance.

NATURAL GAS SAFETY Safety First – Providing Safe Natural Gas Service The health and safety of LG&E’s Customers and employees and the general public are our highest priorities. LG&E believes strongly in the concept that safety is everyone’s responsibility. LG&E’s employees and contractors will not perform any work in areas considered to be unsafe or install or connect any natural gas facilities that are, in the opinion of our employees or contractors, unsafe or not in compliance with LG&E’s requirements or governing codes and regulations. Both LG&E and Customer-owned natural gas facilities must be planned, designed, built, maintained, and operated in a manner that minimizes the risk of injury and property damage during construction and throughout the life of the facility. Personal Safety Using Natural Gas Safely It is important that users know how to safely use natural gas and care for natural gas appliances. One of the first steps to prevent accidents is to ensure that natural gas appliances and equipment have been properly installed, adjusted, vented and inspected. Appliances should be installed, serviced and repaired by professionals. Other safety precautions that should be taken include the following: Follow manufacturers’ instructions for the installation, operation and maintenance of gas equipment and

appliances. Never use a kitchen range to heat a room. This action can damage the range and produce dangerous carbon

monoxide (CO) gas. In addition, top burners should not be used for space heating; such usage can be a fire hazard.

Since burning natural gas produces a high radiant heat, keep flammable materials (e.g., cloth, paper, paints,

and solvents) away from appliances. Provide proper ventilation in areas around furnaces, water heaters, dryers, ranges, etc. Have routine maintenance performed on appliances to keep them clean and in proper working order. Keep natural gas kitchen ranges clean. Rinse and dry the burners before reinstalling. Be careful not to

damage or change the settings on the range burners’ air shutters or sleeves. Ensure that all vents and chimneys are free from blockage. Clean or change filters on furnaces and dryers regularly. Maintain the gas lines that are located inside and outside the house to prevent leaks. The gas service lines

buried from the property line to the house and all house line piping within the house are the responsibility of the property owner. LG&E will periodically survey all outside piping for leaks and will advise you if any maintenance is required on your portion of the service line. LG&E will also inform you of any corrosion that is discovered on any outside piping that is exposed to the weather and advise you to paint the affected area.

Contact the Kentucky Dig Safely, also known as “BUD” (Before You Dig), at (800) 752-6007 to determine the

location of utility-owned service lines (including LG&E’s natural gas lines) before you begin any yard excavation. This is a free service offered by Kentucky Dig Safely.

Do not operate any electrical switches, equipment or appliances or use open flames if you smell a natural gas

odor. Leaking natural gas can ignite.

Teach Natural Gas Safety To Your Family Every family member should know how to find and turn off the natural gas shut-off valve at the meter. This valve should be closed only in the event of a natural gas emergency in your home. If you turn off the shut-off valve, do not turn it on again. Call LG&E at (502) 589-5511 (outside Louisville at (800) 331-7370), and let us re-establish your gas service for you. Teach small children to stay away from the gas range and gas-burning appliances. Do not let children play or climb on the meter piping on the outside of the house; do not allow them to swing

from or play with pipes leading to water heaters or ranges. Practice safety drills for getting the family out of the house at night in case of a natural gas emergency or any

other emergency such as a fire. What To Do If You Smell Natural Gas If you smell gas and cannot find the source(s), immediately go to a location where no natural gas odor exists,

such as a neighbor’s house, and call LG&E at (502) 589-5511 (outside Louisville at (800) 331-7370). A spark from using a telephone or cellular telephone inside the house could ignite the gas.

If the odor is faint, get everyone outside and leave doors and windows open to ventilate the area. A faint odor

of gas may mean that a pilot light has gone out and should be re-lit. If the odor is strong, get everyone out of the house immediately.

Never use a telephone or cellular telephone, switch a light on or off, or light a match if you smell natural gas.

Never look for a natural gas leak with a lighted flame or match. Do not try to re-light a gas furnace, water heater, or range. Facts About Natural Gas

Natural gas is an abundant, clean burning, energy-efficient fuel. Natural gas is colorless, odorless and tasteless. As a safety precaution, a chemical called Mercaptan is

added to natural gas. This chemical provides a distinctive odor that will alert persons to a potential safety hazard. Mercaptan has the smell of rotten eggs. Odors that are sometimes mistaken for natural gas can come from a variety of sources, such as petroleum products (especially gasoline), marsh gas, sewer gas, and industrial gases.

Natural gas is not toxic (i.e., poisonous). No health hazards exist from the exposure to natural gas. However,

if present in sufficient quantities to displace the oxygen in the air, it can cause drowsiness and eventual suffocation due to lack of oxygen.

Natural gas is lighter than air. When released in an open space, natural gas will rise and diffuse rapidly. If

confined in a closed space, natural gas will rise to the highest level. The air in the space will be displaced from the top downward. Therefore, to ventilate a room, windows should be open from the top and bottom portions of the room.

To burn or explode, natural gas must mix with air in the proper amount (i.e., 4% to 15% natural gas to air) and

be ignited at an ignition point of 1,100oF – 1,200oF. This ignition point is reached by pilot lights, flint sparks, matches, sparks from electrical switches and motors, or electrostatic sparks.

A properly burning natural gas flame will have a crisp blue color. If natural gas is burned without enough air, it may produce carbon monoxide, a poisonous gas. A person exposed to carbon monoxide may complain of dizziness, headache, nausea, fatigue, and other flu-like symptoms.

Natural gas should not be confused with liquefied petroleum gas. Liquefied

petroleum gas is more commonly called L.P., bottle gas, propane, butane, and various other trade names. It is heavier than air and collects in low places when not confined.

Meter Tampering Individuals, who tamper with natural gas meters and piping to make it show less consumption, or bypassing the meter entirely, endanger their own lives. They also risk the lives of their family and neighbors. Meter tampering can create a dangerous situation that can lead to serious and sometimes fatal injury from fire or explosion.

RECOMMENDATIONS FOR A SUCCESSFUL PROJECT Plan your work. Planning is vital for obtaining a successful natural gas project (e.g., service, installation, or

repair). It includes, but not limited to, reading and following appropriate sections of the LG&E Customer Gas Piping Handbook, obtaining all necessary permits, deeds and/or easements, and acquiring necessary materials and equipment. If you have questions concerning your project, contact LG&E. Contact information for LG&E is located in Section 1 – General Information under Important Telephone Numbers.

Pressure test the house line piping. In accordance with Subsection 5.9.1, house line piping should be

pressure tested to detect leaks prior to contacting LG&E for service connection. Note: LG&E will not provide natural gas service to house line piping that is leaking.

Make sure that the house line piping is ready. In accordance with Subsection 2.1.8 a. iii., to qualify for

natural gas service, the house line piping system must be extended to an operable natural gas burning appliance(s) or to a plugged valve(s) at the proposed appliance(s) locations. In addition, the house line piping should be pressure tested to detect any leaks on the piping system.

Avoid damaging the tracer wire. In accordance with Subsection 3.11.1, care must be taken to avoid

damage to the tracing wire during placement and compaction of backfill. Use a clamp on the service riser. In accordance with Subsection 3.16.1 b., the service riser must be

securely supported using split ring clamps or substantial mounting brackets in accordance with the applicable meter loop drawing. Polyethylene pipe or flexible riser casing must not be relied upon to contribute to the support of the meter setting.

Make sure that the meter loop is not installed too low (i.e., service head adapter below grade). In

accordance with Drawing Nos. GSC – 30-20-004, GSC – 30-20-005, and GSC – 30-20-006, the meter loop shall be installed such that the bottom of service head adapter is either at a minimum of six inches (6”) or a maximum of twelve inches (12”) above grade.

Install a shutoff valve on the house line piping going to a fireplace that is designed to burn wood or

other solid fuel. In accordance with Subsection 5.2.3, the shutoff valve shall be located outside of the firebox and accessible in the same room. This valve is not a part of the fireplace. If corrugated stainless steel tubing (CSST) is used, the valve must be installed at the end of the CSST piping so that only steel fittings are used to actually connect the fireplace. In addition, this valve should be installed so that it is accessible at all times, even if it is in the basement.

Be present to allow LG&E personnel access to natural gas appliances for the activation of gas service. To activate natural gas service for new service connection, service replacement, houseline repair, etc., LG&E needs access to all gas appliances. It is imperative that the Customer be present to grant access to the premises.

Allow adequate time for LG&E to get utility locates. In accordance with the Excavation Safety section,

LG&E is required to provide prior notification for planned excavation work. Thus, if LG&E needs to excavate to provide gas service, it will need to wait two full business days for other utility companies to locate and mark their buried utilities with color-coded paint, flags or stakes.

Provide a two foot by four foot (2’ x 4’) excavation hole at the property line for new or replacement

service lines. In accordance with Section 3.2.2 a. ii. and 3.2.2 b., Customers are required excavate a 2’ x 4’ hole for new or replacement service lines.

GENERAL INFORMATION 1.1 Introduction

The Louisville Gas and Electric Company, referred to herein as "LG&E,” desires to cooperate with all concerned parties to further the proper installation and use of natural gas. To achieve this goal, the Customer Gas Piping Handbook was created to provide information to gas customers and potential gas customers regarding the installation and operation of gas piping and appliances. Gas customer, referred to herein as “Customer,” is used to address the party responsible for meeting the requirements of this handbook. While the Customer’s mechanical contractor, plumber and/or builder will in practice utilize this information the most, the Customer is ultimately responsible for meeting the requirements of this handbook. However, LG&E representatives are available to assist Customers in complying with requirements of this handbook.

1.2 Scope

This handbook provides specifications and construction standards for the installation of service lines and Customer metering facilities. It also provides guidance for the installation of house lines and gas appliances for single-family and multi-unit dwellings with individual meters and for small commercial and industrial customers served with natural gas from LG&E. In addition, it meets or exceeds not only the Kentucky Public Service Commission (KPSC) regulations but also the NFPA 54 (National Fuel Gas Code), Kentucky Uniform Building Code, and other relevant publications. However, the information contained herein does not preempt any of the rules, codes or regulations contained in the aforementioned publications. It is the Customer’s responsibility to notify LG&E of any conflict between this handbook and the requirements of any of the above publications.

1.3 Service Rates, Rules and Regulations 1.3.1 Kentucky Public Service Commission

light, heat, power, refrigeration, or air conditioning. 1.5.2 Approved Gas Valve – A natural gas valve that meets or exceeds the minimum requirements of

applicable federal, state, and local codes and regulations. 1.5.3 BTU – British Thermal Unit. A measure of heat energy. One BTU is the quantity of heat that will raise the

temperature of one pound of distilled water by one degree Fahrenheit (1oF) at 70 degrees Fahrenheit (70oF).

1.5.4 BTUH Input Rating – The heat energy input, in terms of BTU per hour, required to properly operate a

gas-burning appliance. The amount of natural gas needed to operate the appliance is determined by the BTU input rating. One standard cubic foot of natural gas will produce slightly over 1,000 BTUs in normal efficient combustion.

1.5.5 Cathodically Protected Piping – Underground coated steel piping that has cathodic protection applied

to retard corrosion. The cathodic protection can be provided by the use of galvanic anodes, such as magnesium anodes.

1.5.6 Company – When used herein, refers to Louisville Gas and Electric Company (LG&E), a wholly owned

subsidiary of LG&E and KU Energy LLC. 1.5.7 Company’s Service Connection – Piping from LG&E's gas main to a point within one foot of the

Customer's property line or easement line, adjacent to the main, for the purpose of supplying gas to the Customer's service line.

1.5.8 Corrosion Prevention – Measures taken to prevent corrosion and prolong the life of buried metallic

piping, and aboveground piping exposed to weather or a corrosive environment. 1.5.9 CSST – Corrugated Stainless Steel Tubing. Gas house piping systems incorporating corrugated

stainless steel tubing and custom designed fittings are for use above ground only. In order to be acceptable under code requirements, each installer must be certified as trained by the agent(s) or manufacturer(s) of system(s) being used and must be trained on all installation requirements of that manufacturer.

1.5.10 CTS – Copper Tube Size. The size convention used to describe the size of polyethylene gas piping in

terms of standard copper tubing. The actual outside diameter of CTS-sized tubing is one-eighth inch (0.125") larger than the nominal CTS.

1.5.16 Low, Elevated, Medium, And High Pressure – LG&E's classifications of operating pressures in the gas mains throughout its gas system are as follows: a. Low Pressure – The system operating pressure is essentially the same as the pressure delivered to

each Customer’s meter and house line (i.e., 0.25 PSIG (7 inches Water Column)). b. Elevated Pressure – LG&E’s elevated pressure systems operate at 2.0 PSIG at their sources of gas

supply. A pressure regulator is required ahead of each Customer’s meter to maintain a constant standard delivery pressure of 0.25 PSIG (i.e., 4 ounces per square inch or 7 inches Water Column).

c. Medium Pressure – LG&E’s medium pressure systems operate at pressures higher than 2.0 PSIG

up to 60 PSIG. LG&E has several medium pressure systems operating at different pressures. A pressure regulator is required ahead of each Customer’s meter to maintain a constant delivery pressure that is normally the standard 0.25 PSIG. Higher delivery pressure can be delivered to the Customer if necessary, limited by the characteristics and operating restraints for the particular medium pressure system.

d. High Pressure – LG&E’s designation for high pressure includes any gas transmission system or

distribution system that is subject to operation at over 60 PSIG. A pressure regulator is required ahead of each Customer’s meter to maintain a constant delivery pressure that may be the standard 0.25 PSIG or higher if necessary.

1.5.17 Main – Gas system piping located in a public highway, street, alley, or private easement that is used to

distribute gas. 1.5.18 Meter Loop – Piping provided by the Customer to accommodate the installation of the gas meter(s). 1.5.19 PSIG – Pounds per Square Inch Gauge. A standard unit of measurement for describing the pressure of

gas or liquid. 1.5.20 SDR – Standard Dimensional Ratio. A numerical term used to describe the wall thickness of

polyethylene pipe. SDR is derived by dividing the actual outside diameter of the pipe by the wall thickness and is an indication of the strength of the pipe.

1.5.21 Service Head Adapter – A transition fitting that adapts polyethylene gas pipe to steel pipe, in a manner

in which the polyethylene pipe is shielded against damage from physical force and solar radiation, with all pressure containing metallic components located above ground.

1.5.22 Standard Delivery Pressure – The gas pressure normally delivered to residential and small commercial

Customers, which is approximately four ounces (4 oz) per square inch, seven inches (7”) of Water Column, or 0.25 PSIG.

1.5.23 Tamperproof Gas Valve – A gas valve in which the core cannot be easily removed, either accidentally or

intentionally, with ordinary hand tools. 1.5.24 Total Connected Load – The total heat input in BTUH for all gas burning appliances and equipment

installed. 1.5.25 W.C. – Water column pressure. A standard unit of measurement for describing the pressure that is

expressed in terms of a water depth exerting an equivalent force. Typical gas pressure delivered to Customer's house piping is seven inches (7") W.C., which is approximately 0.25 PSIG. The loss in gas pressure that results from gas flowing through a piping system is generally expressed in inches of W.C. drop.

Note:

The medium pressure service line capacities shown in Table 3.3 are conservative and may be used without exception on any service supplied from an LG&E medium pressure gas system. In some cases, a greater capacity will result from a higher system operating pressure. If additional capacity is needed to utilize an existing medium pressure service line, or to enable insertion through an existing steel service, the Gas Operations Center in your area should be consulted.

3.8 Service Line Protection 3.8.1 Creek Crossings and Drainage Ditches

Service lines crossing creeks or drainage ditches must be adequately protected against damage that may result from erosion or dredging. For creeks and ditches in which water is normally present or flowing, the service line must be encased in a steel pipe or otherwise protected in accordance with a method acceptable and approved by LG&E.

3.8.2 Ends of Steel Casing

a. Each point in which pipe enters or leaves a steel casing pipe must be properly prepared and protected from damage resulting from contact with sharp metal edges and from sheering forces from ground settlement.

b. The inside of the steel casing must be reamed or filed to remove burrs and to provide a beveled or

rounded edge, and a protective insert bushing must be in place during and after the insertion operation.

Page 38: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

ii. The Louisville telephone number for Kentucky Dig Safely is (502) 266-5123. From outside the

Louisville local area, Kentucky Dig Safely can be reached toll free at (800) 752-6007. iii. There is no charge to the Customer or contractor for calling Kentucky Dig Safety or for the locating

services that are normally provided.

b. Utility Clearance To the greatest extent practical, a minimum clearance of one foot (1’) horizontal distance should be maintained between the gas service and underground structures, water service lines, electric service lines, telephone lines, and cable television service lines. However, a minimum of three feet (3’) horizontal clearance is recommended between gas service lines and underground gasoline or fuel oil storage tanks, underground sewer lines, septic tanks, or lateral fields. Refer to Drawing No. GCS 20-10-001, Acceptable Service Line Locations.

c. Depth of Cover

Service lines must have at least 18 inches (18”) of cover, except where prevented by solid or consolidated rock. In case of rock, or other obstructions, service lines shall be as deep as practical, but with not less than 12 inches (12”) of cover. However, if solid rock prevents installation with 12 inches (12”) cover, a minimum of nine inches (9”) will be allowed providing that the service line is installed inside a rigid plastic or steel casing with the top of the casing below the surface of the rock. Refer to Drawing No. GSC 20-20-002, Installation of Gas Service Line in Shallow Rock.

3.9.2 Direct Burial

a. Backfill and Trench Bottom Requirements

i. Special care must be exercised to assure that all soil in contact with the gas pipe is free from rocks, bricks, nails, building materials, etc., that may damage the pipe surface. If necessary, a sand or sifted soil cushion at least six inches (6”) thick may be required above and below the pipe.

ii. Backfill material containing the above-mentioned foreign materials may not be used. As with any

underground pipe, backfill shall be carefully replaced in several well compacted layers. Special attention shall be paid to the area around the polyethylene pipe at the meter riser to avoid straining the meter loop brackets and service head adapter if used. If good backfill material is unavailable, it is permissible to encase the polyethylene service line in a rigid plastic or steel pipe of a larger size.

Page 39: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

24

iii. The trench bottom for gas service lines installed by direct burial must be smooth and free of abrupt changes in elevation. The soil in the trench bottom must be free of sharp rock or foreign material that may damage the pipe. If rock is encountered, a minimum of six inches (6”) of sand or sifted soil cushion must be placed below the pipe.

iv. As an alternative to sand or sifted soil cushion, a steel pipe, PVC pipe, or other rigid plastic pipe

may be installed on the ditch bottom to use as a protective sleeve for insertion.

b. Utility Clearance

If a gas service line is installed in the same ditch with other utilities or underground facilities, a minimum of one foot (1’) horizontal clearance shall be maintained and the gas service line must be supported on well compacted soil. If conditions or situations prevent meeting these requirements, the Gas Operations Center in your area should be consulted. The requirements of this article do not preclude participation in joint trenching projects. However, a detailed plan must be submitted to LG&E for approval prior to the installation.

3.9.3 Trenchless Technology

a. Installation of service lines by plowing, horizontal drilling or other trenchless technology is subject to the approval of LG&E in advance. In order to achieve approval for horizontal drilling, an operating plan must be presented and observation of an installation by a LG&E inspector may be required.

b. The plan must address the following items:

i. Minimum qualifications of the lead person, performing the installation. Note: The lead person

must be on the job site while the work is being performed. ii. Requirement to notify Kentucky Dig Safely at least two business days prior to starting

construction, as well as all other reasonable precautions to avoid interference with sewers, drains, and other buried facilities.

iii. Requirement not to damage other underground utilities. To meet this requirement, test holes

should be dug by hand over locations where the proposed service line will cross the existing underground utilities. The test holes should be dug to a depth that equals or exceeds the depth of the proposed service line.

iv. Description of soil types and conditions acceptable and unacceptable for the installation method

described. v. If polyethylene pipe is used, provision for limiting tensile stress on the polyethylene pipe to a level

not damaging to the pipe. vi. Quality control program to ensure that soil and installation conditions are proper and that proper

depth of burial has been attained. vii. Criteria for the inspection of the leading pipe to assure that it had not been damaged by tension

or abrasion. Visual inspection and dimensional testing with a cold ring clamp is suggested.

b. The existing service line must meet minimum depth requirements and may not pass under buildings or

go through other prohibited locations.

3.10 Casings 3.10.1 Installation of Casings

Plowing or directional boring may be used as alternatives to direct burial for installation of casing. 3.11 Tracing Wire 3.11.1 A tracing wire consisting of stranded AWG 14 or larger insulated copper wire must be installed with each

polyethylene service line from the meter riser to the property or easement line. Contact between the tracing wire and the polyethylene gas pipe is to be avoided. A clearance of three inches (3”) to six inches (6”) should be maintained. Care must be taken to avoid damage to the tracing wire during placement and compaction of backfill.

3.11.2 When inserting polyethylene pipe through an existing steel service, tracing wire must be provided

between the service riser and the casing, across each gap in the casing, and from the end of the casing to the property line or easement line. The tracing wire must be electrically attached by brazing, thermite welding, or with good quality electric ground clamps to the casing pipe. Each connection between the tracing wire and casing pipe must be coated with an electrically insulating mastic intended for burial. Brazing or thermite welding must be performed before the polyethylene is inserted. Refer to Drawing No. GCS 20-20-005, Attachment of Tracing Wire.

3.11.3 As an option, the tracing wire may be inserted with the polyethylene gas pipe through an existing steel

service pipe provided that proper clearance is maintained between the wire and polyethylene pipe before and after they exit the casing pipe.

3.11.4 When installing a PVC or other plastic casing pipe by trenching, plowing, or directional boring, the tracing

wire must be installed outside of the casing and may be taped or otherwise secured to the outside of the casing at intervals as necessary to facilitate installation.

3.12 Branch Connections

No tees or branch connections are allowed in Customer service lines below grade. If more than one gas meter is required, all tees shall be above grade and all meters and service line interconnections shall be within plain sight at a common location.

shall be visually inspected and pressure tested by LG&E. 3.13.2 Service lines installed by direct burial must be visually inspected by LG&E before the areas of open

excavation may be backfilled. 3.13.3 Service lines installed by trenchless technology (e.g., plowing or boring) must be visually inspected by

LG&E before the areas of open excavation (including areas at the property line and the meter assembly) may be backfilled.

3.13.4 Service lines installed by insertion (i.e., in a newly installed PVC sleeve or existing steel service line) must

be visually inspected by LG&E before the areas of open excavation (including areas at the property line and the meter assembly) may be backfilled. However, areas of open excavation over the PVC sleeve or existing service line may be backfilled without being inspected by LG&E.

3.14 Service Lines Per Building or Property 3.14.1 Single Family Dwellings

Lots that are zoned for single family dwellings shall be entitled to one gas service line per lot. Single family dwellings include homes, manufactured homes, etc.

3.14.2 Separate Buildings on One Parcel

a. Each building containing one or more complete residential dwelling or commercial business units located within a single parcel of land may be entitled to one service line. This entitlement does not apply to garages, storage sheds, or other outbuildings that serve as satellites to the principal units served. Individual units that share a common wall or are otherwise connected are to be considered collectively as one building.

b. LG&E reserves the right to limit the number of service lines within a single parcel of property when

necessary to ensure safe operation or when separate buildings can be properly served from a single meter location.

3.14.3 Common Building on Separately Deeded Parcels

Each common building structure that contains units on separately deeded land parcels is generally entitled to a single service line per building. In the event the common building contains nine or more units, a second service line may be provided at LG&E's discretion. The second service will be located at the opposite end of the building as the first service. It is the developer, builder, or customer's responsibility to ensure easements or common ground is established through which the right to install, operate, and maintain the service line is legally granted.

3.14.4 Entitlements and Restrictions

The entitlements and restrictions stated above are based upon typical residential and small commercial installations. The number of service lines allowed for large lots, farm land, industrial property, etc., will be determined by the Gas Operations Center in your area based upon the merits of each request.

3.15 Joining Requirements for Gas Service Line Piping 3.15.1 Sections of polyethylene pipe may be joined using mechanical fittings, socket fusion, butt fusion, or

electrofusion.

a. Mechanical fittings must be approved by LG&E, and the heat fusion of polyethylene pipe must be performed using procedures that have been approved by LG&E.

Page 42: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

27

b. Heat fusion joints must be made in conformance with the qualified written procedures developed for

each particular brand of pipe. Use of proper tools for making heat fusion joints is essential. 3.15.2 Polyethylene and steel pipe may be joined together using mechanical fittings or transition fittings.

Mechanical and transition fittings must be approved by LG&E prior to installation. 3.15.3 As much as practical, polyethylene service lines should be run in a single continuous section without

joints. For coil pipe, a maximum of one (1) mechanical joint per one hundred feet (100’) of service in addition to the joint at the meter riser is recommended. For straight length pipe (i.e., usually pipe three-inch (3") IPS and larger), to the greatest extent practical, the piping should be installed using full lengths, which are typically forty feet (40’) long.

3.15.4 A minimum of three inches (3”) of slack per one hundred feet (100’) of polyethylene gas service line shall

be provided to allow for thermal contraction. 3.15.5 Qualifications to Join Gas Service Line Piping

a. Federal Pipeline Safety Regulations require any person that joins gas service line piping to be qualified and to use qualified written procedures. This requirement includes polyethylene to polyethylene as well as polyethylene to steel joints.

b. Persons joining sections of polyethylene pipe with mechanical fittings can be qualified by an

acceptable agency such as the Kentucky Gas Association or by the manufacturer of a particular fitting.

c. Acceptance of qualifications to make heat fusion joints may be obtained through LG&E. For heat

fusion qualifications to be accepted by LG&E, one or more sample joints must be made in the presence of an authorized LG&E inspector and must be submitted to the inspector for destructive testing.

d. LG&E will use the guidelines for acceptance or rejection of joints as set forth in the manufacturer's

qualified written procedures to determine heat fusion qualifications. e. Homeowners, tenants, or others installing a polyethylene service line not for profit may be eligible to

obtain a "homeowner’s" permit. This permit is issued to the person making the mechanical joint or joints in the polyethylene gas pipe following a brief training session. Contact the Gas Operations Center in your area for information regarding homeowner’s permits. This permit is not available to commercial installers.

3.16 Service Riser Requirements 3.16.1 General

a. The service line riser should be plumb and meter connections should be level with the correct distance between openings. Use of excessive fittings should be avoided.

b. The service riser must be securely supported using split ring clamps or substantial mounting brackets in

accordance with the applicable meter loop drawing. Polyethylene pipe or flexible riser casing must not be relied upon to contribute to the support of the meter setting.

c. The transition from polyethylene to steel at the service riser must be made using approved fittings in a

configuration acceptable to LG&E. See Drawing Nos. GCS 30-20-004, Meter Riser for Use with Polyethylene, GCS 30-20-005, Flexible Meter Riser for Use with Polyethylene Gas Service Line, GCS 30-20-006, Service Head Adapter/ Straight Pipe Meter Riser for Use with Polyethylene Gas Service Line, and GCS 30-20-007, Anodeless Riser for Large Polyethylene Gas Service Line, for typical meter riser installations.

GAS METER INSTALLATIONS 4.1 Standard Meter Capacity 4.1.1 To assure proper operation, each gas meter must be the proper size and type for the maximum gas

demand and required pressure. The maximum gas demand is determined by adding the BTU input ratings of all gas burning devices that may possibly be operated simultaneously. Furnaces, space heaters, water heaters, boilers, pool heaters, fireplace logs, gas lights, gas clothes dryers and gas generators should be included at their maximum input ratings. Domestic kitchen ranges and outside grills may be considered to be 30,000 and 20,000 BTUH respectively as they rarely are operated at full capacity for extended periods with other appliances.

4.1.2 A standard house meter, at a two inch (2”) W.C. differential, will properly serve a gas demand up to 175,000

BTUH (simultaneously operation) or 375,000 BTUH (diversified operation). For greater gas demands, consult the Gas Operations Center in your area to determine the correct meter size.

4.2 Acceptable Meter Locations 4.2.1 General

a. Meters shall be located in ventilated spaces readily accessible for examination, reading, replacement, or necessary maintenance.

b. Gas meters shall not block normal passage on sidewalks or block ingress or egress through doors or

emergency exits. c. Gas meters shall not be placed in locations where they will be exposed to excessive dirt or corrosive

materials from manufacturing processes, or beneath condensate drains or roof drains. d. Outside gas meters shall be located at least 18 inches (18”) from any air intakes into a building, as

measured from the final elbow on the service riser (refer to Drawing No. GCS 30-10-003, Acceptable Gas Meter Locations). Air intakes include dryer vents, furnace vents for intake or exhaust, windows that may be opened, ventilating fans, louvers, or foundation grills.

e. Outside gas meters shall be located at least 36 inches (36”) from any likely ignition sources, as

measured from the final elbow on the service riser (refer to Drawing No. GCS 30-10-004, Acceptable Gas Meter Locations). Likely ignition sources include the electric meter and meter pan, electric circuit breakers, air conditioning units, or other electric devices.

f. If the separations listed in Subsection 4.2.1 d. & e. cannot be attained, the regulator vent must be

piped to a location that meets the separation requirements listed above. Additional separation may be required for large volume pressure regulators with built-in internal relief devices.

4.2.2 New Service Installation

Gas meters shall be located outside.

4.2.3 Existing Installations

a. When it is necessary to relocate the gas meter inside a building for a replacement service line, the Gas Operations Center in your area should be consulted for specific installation requirements.

b. Replacement Gas meters located inside buildings or under roofs may require additional

regulator/relief valve vent piping. The Gas Operations Center in your area should be consulted for specific installation requirements.

4.3.2 Gas meters should not be installed under decks, in crawl spaces, or in other areas with less than six feet (6’) of headroom.

4.3.3 Gas meters should not be enclosed by decks, sunroofs, etc. 4.3.4 Maximum height from the floor to the top of any meter should not exceed five feet (5’). However, an

exception may be made to clear expected high water elevation in areas prone to flooding. 4.4 Multiple Meters 4.4.1 When two (2) or more meters are connected to the same service line, all meters and interconnections to the

service line must be within plain sight at a common location and should be adjacent to the building nearest the gas main. The house line side of each meter loop in a multiple meter setting must be permanently tagged with the identity of the unit served by that meter.

4.4.2 Multiple meter installations serving residential and small commercial Customers using standard meters are

required to be constructed with prefabricated meter loop assemblies to the greatest extent practical. See Drawing No. GCS 30-20-206, Typical Multiple Meter Installation Prefabricated Meter Loops, for a multiple meter installation using prefabricated meter loop assemblies.

4.5 Meter Loop Assemblies 4.5.1 Fabrication

a. Prefabricated Meter Loop Assemblies

i. Prefabricated meter loop assemblies are required for service to Customers utilizing standard meters up to 250 CFH nominal capacity (i.e., at 0.5” W.C. differential) whenever total demand and character of demand permit. For single meter installations see Drawing Nos. GCS 30-20-201, 1” Prefabricated meter Loop, GCS 30-30-201, Low Pressure Meterset Assembly, GCS 30-30-202, Medium Pressure Meterset Assembly 1 NPS x 20 LT with Regulator, and GCS 30-30-203, Elevated Pressure Meterset Assembly 1 NPS x 20 LT with Regulator, for piping details of standard house meters using prefabricated meter assemblies.

ii. For maximum gas demand of over 300,000 BTUH served from a low pressure (i.e., 0.25 psig)

system, or where a bypass operation must be performed (such as for maintenance to a meter or pressure regulator) without interruption of normal operation, the prefabricated meter loop should not be used. Refer to Section 4.2.2, Field Fabricated Meter Loops.

If all meters are served from a single manifold, one valve shall be provided ahead of that manifold, preferably at the top of the service riser. See Drawing GCS 30-10-002, Master Valve Requirements for Multiple Meter Installations, Figures A&B.

ii Master valves for two or more manifolds. If meters are served from more than one manifold, a

master valve is required for each manifold. See Drawing GCS 30-10-002, Master Valve Requirements for Multiple Meter Installations, Figure C.

iii. Bypass valves are required on meter loops one and a half inches (1-1/2”) and larger, and

on some field fabricated one inch (1”) meter loops, in order to prevent major inconvenience or interruption of commercial process which would result from the shutting off of gas for meter change operations. Generally, any meter loop that has a meter with a capacity of 425,000 BTU/H or greater at one half inch (½”) water differential will have a bypass. See Drawings No. GCS 30-20-301, 1” Meter Loop with By-pass, and GCS 30-20-302, 1½ Meter Loop with By-pass.

b. Inlet Side (or Service Side) of Meter Loop

i. Each new or reconstructed meter loop shall have an approved tamperproof gas valve of the proper size located on the inlet side of each regulator and meter. Each meter inlet valve or service side bypass valve must have a lock wing or other feature allowing the valve to be locked in the closed position. If served from a low pressure main, elevated pressure main, medium pressure main, or a high pressure main through a primary regulator, each valve must be designed and rated for an operating pressure of at least 100 psig.

Page 49: LGE Gas Handbook

b. When supplying gas to a corrugated stainless steel tubing (CSST) house piping system, the

transition must be made at an approved termination fitting securely anchored to the outside wall. A plastic sleeve must surround the tubing if passing through concrete or masonry. A split ring clamp, or equivalent, will be required if the pipe thread size and mounting configuration of the termination fitting is not sufficient to rigidly support the meter. See Drawing No. GCS 30-20-002, CSST House Piping.

c. Meter loops for manufactured homes shall be rigidly anchored to a free-standing supporting structure

either pre-fabricated or fabricated out of steel or other material resistant to deterioration from weather and contact with ground. Pressure treated lumber shall be allowed only for cross-members and not for support posts. If a manufactured home is subject to relocation, the meter loop location must not block its removal or replacement. See Drawing No. GCS 30-20-205, Mobile Home Meter Loop, for manufactured home meter loops. If a manufactured home is permanently and rigidly anchored to a masonry foundation, the meter loop may be anchored to the foundation and the piping may be rigidly connected to the manufactured home.

4.5.5 Atmospheric Corrosion Protection

Meter loop piping installed outdoors or in other locations that are subject to atmospheric corrosion must be properly coated or otherwise protected from atmospheric corrosion. A good quality paint intended for exterior use on metal, applied to a properly prepared surface, may be used.

4.6 Meter Protection

4.6.1 Barricades

Gas meters located within three feet (3’) of driveways or other driving areas shall be barricaded or otherwise protected from vehicular damage. Meters located farther than three feet (3’) from driveways serving commercial or industrial operations require barricades if subject to contact by trucks, forklifts, or other mobile equipment.

SIZING OF GAS HOUSE LINE PIPING 6.1 General

The information contained within this section is provided to assist the Customer in determining correct house line pipe sizes to assure satisfactory operation of gas appliances. This section is intended for standard 4 ounces (i.e., seven inch (7") Water Column (W.C.) or 0.25 psig) delivery pressure only. While only one method of determining adequate pipe sizes is illustrated in this Handbook, other engineering methods may be used.

6.2 Reference Sources

For systems operating at higher pressures or for other sizing methods, the NFPA 54 National Fuel Gas Code, BOCA National Mechanical Code, or other applicable standards should be consulted.

6.3 Pipe Sizing

a. In order to assure adequately sized house piping, LG&E recommends designing gas house line systems to operate with a pressure drop of not more than one half inch (0.5") W.C. from the meter to the last appliance at the maximum demand of all connected appliances subject to simultaneous operation. The possibility of increased gas demand, due to installation of additional appliances or due to replacement of existing appliances with higher BTUH input appliances, should be considered. Standard engineering methods, using industry accepted formulas or tables published in national codes for determining pressure drop in piping systems with natural gas of 1,000 BTU per standard cubic foot heating value and 0.6 specific gravity, may be used.

b. Corrugated stainless steel tubing systems must be designed with sufficient tubing size to operate with

low pressure gas, unless the availability of greater pressure is confirmed by the Gas Operations Center in your area. Delivery pressure in excess of seven inches (7") W.C. cannot be provided from low or elevated pressure gas distribution systems. The Gas Operations Center’s telephone number is listed in Section 1 – Important Telephone Numbers.

6.4 Pipe Sizing Method

The following procedure may be used to determine proper pipe size from the tables herein:

Step A: Compile a list of all gas burning devices and their maximum gas consumption based upon the

manufacturers’ input BTUH ratings. Convert the input rating in BTUH to CFH (cubic feet of gas per hour) by dividing by 1,000. A list of approximate gas input ratings for typical appliances is located in Table 5.4.2.1 of the NFPA 54-2006 National Fuel Gas Code.

Step B: Starting with the outlet of the gas meter, make a line diagram of the piping system to each

appliance connection, showing lengths in feet of each pipe segment and gas demand in cubic feet per hour for each appliance to be connected.

Step C: Determine the demand to be supplied by each pipe segment by adding together the demand of

each appliance served through that pipe segment.

Step D: Determine the length from the gas meter to the farthest appliance connection.

Step E: Select the proper pipe capacity table. Tables 6.1 and 6.2 are provided for schedule 40 metallic pipe with a three-tenths inch (0.3”) and one-half inch (0.5”) W.C. pressure drop, respectively. Table 6.3 is provided for corrugated stainless steel tubing (CSST) pipe with a one-half inch (0.5”) W.C. pressure drop.

Page 61: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

46

The one-half inch (0.5”) W.C. pressure drop table should be used for applications where no additional capacity is expected. The three-tenths inch (0.3”) W.C. pressure drop table should be used for applications where additional capacity is desired to provide for future expansion or installation of higher BTUH appliances. Using the appropriate capacity table, select the column showing the length determined above, or the next greater length if the exact length is not shown.

Step F: For each pipe segment, find the pipe size that has a capacity equal to or greater than the demand

to be carried for the design length determined above. EXAMPLE – Determining Proper Pipe Sizes For Single Family Dwelling Find the correct pipe sizes to assure proper operation of the gas appliances in a dwelling equipped with a gas burning furnace, water heater, clothes dryer, and kitchen range. There are no plans for adding additional appliances or installing high BTU appliance (e.g., “tankless” hot water heater). Step A – List the appliances with their BTUH input ratings and determine the gas demand in CFH (cubic feet per hour). To determine CFH, divide the BTUH input rating by 1,000. 120,000 BTUH - Forced Air Furnace 120 CFH 45,000 BTUH - Water Heater 45 CFH 35,000 BTUH - Clothes Dryer 35 CFH 60,000 BTUH - Kitchen Range 60 CFH* Note: *For determining meter capacity and service line size, a value of 30 CFH may be used for domestic kitchen ranges since it is very rare for all burners to be on at full capacity simultaneously. To be consistent with applicable building codes for house piping, the listed BTUH input rating should be used for sizing house piping. Step B – Piping diagram (Not to scale) B F

Step C - Determine demand supplied by each pipe segment Line A-B, 260 CFH Line B-D, 95 CFH Line B-C, 165 CFH Line D-E, 35 CFH Line D-F, 60 CFH Step D - Determine the pipe distance from the meter to the farthest appliance The farthest appliance is the kitchen range at a distance of 40 feet. Therefore, use 40 feet for sizing all segments. Step E - Select the Proper Capacity Table Since no future increase in gas capacity is anticipated, Table 6.1 (0.5” W.C. pressure drop table) was used. However, if additional capacity is anticipated, Table 6.2 (0.3” W.C. pressure drop) is recommended. It provides greater reserve capacity for future or high BTU appliances. Step F - Determine minimum size for each segment of pipe Using Table 6.2 and 40 feet for each segment, determine the size of each pipe segment. Line A-B, 260 CFH, 1" Iron Pipe Size (IPS) Line B-D, 95 CFH, 3/4" IPS Line B-C, 160 CFH, 3/4" IPS Line D-E, 35 CFH, 1/2" IPS* Line D-F, 60 CFH, 1/2" IPS* Note: *Pipe sizes smaller than 1/2" IPS are generally not recommended for permanent house line piping inside buildings.

CORROSION PREVENTION 7.1 General Corrosion Protection Requirements 7.1.1 Protection for Aboveground Steel Piping

All aboveground steel piping, such as service riser or meter loop piping, installed outdoors or indoors in damp locations shall be protected from atmospheric corrosion as required by state and federal pipeline safety regulations.

7.1.2 Protection for Underground Steel Piping All underground (i.e., buried) steel piping, such as service lines, shall be mill coated and cathodically protected as required by state and federal pipeline safety regulations. Similarly, building codes also require underground steel house lines to be coated and cathodically protected.

7.2 Coating Requirements 7.2.1 Specifications

a. Coating for Aboveground Applications

A good quality paint intended for exterior use on metal is an acceptable aboveground coating.

b. Coatings for Underground Applications

i. Pipe

a) All steel pipe used for underground applications shall be purchased with mill applied Fusion Bonded Epoxy (FBE) coating.

b) Fusion Bonded Epoxy (FBE) is the only approved mill applied coating for steel piping in

underground applications.

ii. Joints and Defects

a) At pipe joints and where defects in the pipe coating exist, the underground coatings on steel piping must be one of the approved coatings listed below. For other underground coatings, the coating must be approved by LG&E prior to its installation.

Poly-Butyl Tape - The tape must have a total thickness of at least 25 mils that shall consist

of a 20 mil tar based mastic or synthetic elastomer coating backed by a polyethylene film. It is applicable between the temperatures of -20°F and +130°F.

Wax Tape (i.e., Plastic-fiber felt, saturated with a blend of petrolatum waxes, plasticizers

and corrosion inhibitors, forming a tape wrapper)

7.2.2 Pipe Surface Preparation and Coating Installation

a. Aboveground Piping

i. Clean the piping surface of all dirt, oil, grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent.

ii. Remove all paint that is not tightly adhered.

Page 67: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

52

iii. Remove rust and loose mill scale. Power tool cleaning is recommended. However, hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface.

iv. Paint the piping surface with an aboveground coating. Refer to Section 7.2.1. v. The proper protective clothing, gloves and mask should be worn during the surface preparation and

coating installation process.

b. Underground Piping At Joints and For Defects In Coatings

i. Poly-Butyl Tape

a) For defects in the coating, remove all damaged coating to a point where it is firmly bonded to the pipe.

b) Clean the piping surface (i.e., the welded joints and the defects in the coating) of all dirt, oil,

grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent.

c) Remove all rust, paint, and loose mill scale. Power tool cleaning is recommended. However,

hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface.

d) File or grind smooth all sharp edges or burns to prevent protrusion through the Poly-Butyl tape. e) Apply a thin uniform coating of primer to the clean piping surface and to the mill coated piping

surfaces within the area to be wrapped. The primer used shall be compatible with the coating. The piping surface must be moisture free prior to the priming procedure and remain moisture free throughout application of the Poly-Butyl tape.

f) Allow primed piping surface to dry to a “tacky” stage before application of the Poly-Butyl tape. g) Apply the Poly-Butyl tape over the weld joint or defect area by using a cigarette wrap. A

cigarette wrap consists of using pre-cut strips of Poly-Butyl tape equal in length to the circumference of the pipe plus a minimum of four inches (4”).

h) Apply the Poly-Butyl tape over the entire area (including the weld joint) to be wrapped by

spirally wrapping the Poly-Butyl tape around the pipe using a continuous 50% overlap of tape. The Poly-Butyl tape should be applied under tension. However, the last turn should be applied without tension. The tension in wrapping should be enough to obtain conformability to the surface being coated. The Poly-Butyl tape should then be cut on the downside of the turn and pressed into position.

i) For questions or additional guidance involving the surface preparation and/or the installation of

Poly-Butyl tape, contact the Gas Operations Center in your area.

ii. Wax Tape

a) For defects in the coating, remove all damage coating to a point where it is firmly bonded to the pipe.

b) Clean the piping surface (i.e., the welded joints and the defects in the coating) of all dirt, oil,

grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent.

c) Remove all rust, paint, and loose mill scale. Power tool cleaning is recommended. However,

hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface.

Page 68: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

53

d) File or grind smooth all sharp edges or burns to prevent protrusion through the underground

coating. e) Apply a thin uniform coating of primer to the clean piping surface and to the mill coated piping

surfaces within the area to be wrapped. The primer used shall be compatible with the coating. While it is preferred that the piping surface be moisture free prior to the priming procedure, a damp or wet surface is tolerable when applying wax primer and tape. Where moisture is present, rub and press primer into the piping surface, displacing the moisture and ensuring that the primer adheres to the piping surface.

f) Apply the wax tape by spirally wrapping the wax tape around the pipe using a 25% overlap

(e.g., using a four inch (4”) inch wax tape, a one inch (1”) overlap is required). Press the wax tape into place making sure that no air pockets exist and that the wax tape is in contact with the piping surface. Press and smooth out the lap seams to ensure that the laps are sealed.

g) For questions or additional guidance involving the surface preparation and/or the installation of

wax tape, contact the Gas Operations Center in your area. 7.2.3 Coating Placement

Underground mill applied coating shall extend, at a minimum, six inches (6”) above grade on any steel piping that enters or leaves the ground.

7.2.4 Coating Damage Prevention

a. Care should be exercised in the handling of coated pipe.

b. The bottom of the ditch must be free of rocks or foreign objects that may damage the coating. In addition, backfill shall be free of rocks or debris that may damage the coating. For more detail on backfill and trench bottom conditions, refer to Section 3.10.2 a. – BackFill and Trench Bottom Requirements.

7.3 Electrical Insulation 7.3.1 In order for cathodic protection to be effective, all protected pipe must be electrically separated from any

electrically grounded metallic structure or piping. 7.3.2 Dielectric couplings, dielectric unions, or dielectric flanges may be used at each point the protected piping

extends out of or into the ground. 7.4 Anodes 7.4.1 General

a. Cathodic protection can normally be provided to the coated and electrically isolated underground steel piping by means of a magnesium anode.

b. Magnesium anodes have an insulated lead wire that must be electrically attached to the protected

piping by thermite welding, brazing, or with an approved mechanical grounding clamp.

c. The connection to the piping must be coated with an approved mastic or with tape and primer in the same manner as a joint or defect in the coating.

Page 69: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

54

.4.2 Anode Spacing

a. For maximum effectiveness, one five pound (5 lbs) standard potential magnesium anode should be used for each 50 foot (50’) section of underground steel piping.

b. To the extent practice, the anodes should be evenly spaced over the length of the piping being

protected. 7.4.3 Anode Installation

Anodes should be installed vertically at least three feet (3’) away from the piping with the top of the anode even with or lower than the elevation of the buried piping. See Drawing No. GCS 50-20-801, Vertical Installation Anode and Test Station, for recommended anode installation method.

INSTALLATION AND OPERATION OF GAS BURNING APPLIANCES AND EQUIPMENT 8.1 Customer’s Responsibility

This section of this handbook is included to provide general information regarding safe installation and operation of gas burning appliances and equipment. Whereas LG&E will not knowingly provide gas service to an unsafe installation or operation, it is the installer’s and Customer’s responsibility to install and operate appliances and equipment safely.

8.2 Permits and Inspections 8.2.1 Installation of gas burning furnaces, boilers, space heaters, and other permanently installed equipment is

subject to permit and inspection by the local building inspection authority. 8.2.2 The installer has the responsibility of obtaining the necessary permits and post installation inspections. 8.3 Code Compliance

Appliances and equipment should be installed in accordance with the National Fuel Gas Code, NFPA 54, or other codes as applicable. The National Fuel Gas Code includes provisions for safe location, clearance from combustible materials, combustion air ventilation, and proper venting of combustion fumes.

8.4 Initial Startup of Appliances and Equipment

Upon initial startup, each gas appliance shall be checked for proper performance and operation, and shall be adjusted if necessary. Manufacturers’ written procedures shall be followed when available. At least the following operational tests shall be performed:

8.4.1 Test final gas connections and burner train for leaks.

Using leak detecting solution or a sensitive electronic gas detecting instrument, check all final pipe connections downstream of the manual valve on the house line, including the appliance control valve and burner train. Repair any leaks.

8.4.2 Check gas firing rate.

a. Check the input BTUH rate with the appliance operating at full capacity. b. Do not allow firing rate to exceed the nameplate input rating for the appliance. c. Adjust appliance pressure regulator or change orifices per manufacturers’ instructions if necessary.

Instructions for timing the gas meter to determine firing rate are in Section 9.4 of this Handbook.

8.4.3 Check primary air adjustment.

Visually observe flames for proper characteristics and adjust and secure air shutters if necessary.

8.4.4 Check controls and protective devices.

Gas valves, electronic ignition, high temperature limit controls, flame sensing devices, and other safety controls shall be checked in accordance with manufacturers’ instructions. Any defective controls must be properly repaired or replaced.

Page 73: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

58

8.4.5 Check chimney draft.

a. With appliance in normal operation for several minutes and with doors and windows closed, check for effective chimney performance.

b. Perform match test at draft hood relief opening. A lighted match passed directly beneath the opening

should continue to burn with flame and smoke drawn to the opening. If the match is extinguished, or the flame and smoke are blown away, combustion fumes are spilling out of the opening indicating that the chimney is not effectively venting.

c. Where two or more appliances are vented through a common flue, check all draft hoods. d. Do not continue to operate an appliance that is not properly venting. Corrections must be made for safe

operation.

METER INFORMATION 9.1 How to Read Your Meter

Your natural gas meter is an accurate automatic measuring instrument. It measures the natural gas used to operate all of your natural gas appliances (e.g., hot water heater, furnace, range, etc.) by counting the filling and emptying of the compartments inside the meter. The natural gas used is measured in units of hundred standard cubic feet. A standard cubic foot is the volume of gas at a specific pressure (i.e., (4) ounces (i.e., 0.25 psig)) and temperature (i.e., sixty degrees Fahrenheit (60ºF)). The amount of gas measured is displayed on the meter index. The meter index is located on the front of the meter and may consist of either dials or an odometer. It consists of a reading and test portion. The reading portion will be described in the “Reading Dial Type Index Meters” and “Reading Odometer Type Index Meters”. The test portion is used for the following four applications: Confirm that a meter is operable, Test a gas house line system that is in service for leakage at operating pressure, Calculate the rate of gas consumption for a gas utilizing device, and Enable the accuracy of the meter to be tested in a certified meter proving facility. Your consumption can be determined by subtracting your previous meter reading from your present meter reading. This amount will give you the volume of gas used in units of hundred cubic feet (CCF). Reading Dial Type Index Meters

Normally, an dial type index will have four (4) dials in a horizontal line with the dials labeled from left to right as “1 million,” “100 thousand,” “10 thousand,” and “1 thousand,”. These four dials are used in reading the meter. Also, the index will have two dials labeled “half foot” and “two foot”. The dials are used for meter tests and should be ignored in reading the meter. To read your dial type index meter, look at the four dials with their curved arrows. Read the dials from right to left as follows:

1. Read numbers that the dial pointers passed.

Read the “1-thousand” dial as 1. Read the “10-thousand” dial as 0. Read the “100-thousand” dial as 9. Read the “1-million” dial as 4.

Page 77: LGE Gas Handbook

Customer Gas Piping Handbook Fifth Edition - May 2011

2. When a dial pointer is between two numbers, always record the number that the pointer has passed,

which will always be the smaller number of the two numbers. 3. If a dial pointer is directly on a number, check the dial immediately to the right. The pointer on the

right dial must have reached or passed zero to record the number on the left dial. If the pointer on the right dial has not passed zero, use the smaller number from the left dial.

Following these guidelines, the correct reading for the meter dial shown above is 1094 hundred cubic feet (CCF): Reading Odometer Type Index Meters The odometer type index is a direct read. It reads like an odometer on a car. However, instead of measuring miles traveled, it measures the amount of natural gas used. Similarly, to a dial type index, it also will have two dials labeled “half foot” and “two foot”. The dials are used for meter tests and should be ignored in reading the meter. To read your odometer type index meter, read the number displayed. Each of the number would correlate to one of the four dials illustrated above.

Following these guidelines, the correct reading for the meter dials shown above is 1094 hundred cubic feet (CCF):

9.2 Meter Operability

To confirm that a meter is operable, place any gas utilizing device served by that meter into operation and observe the test dial. Movement of the hand should be apparent, the speed of which will depend upon the rate of consumption for the device.

9.3 Leak Test for A House Line System 9.3.1 To test for leaks in a house line system that is presently in service, perform the following steps:

a. Completely shut off all connected gas utilizing devices, including their pilot lights if so equipped. b. Shut off all manual valves preceding connected gas utilizing devices. c. Mark the position of the test hand on the meter index glass. A felt tip pen, wax pencil, etc., may be

used. d. Observe the test hand for a minimum of ten minutes; any movement indicates that a leak exists. e. Locate and identify leaks so that proper repair or replacement can be implemented. To locate gas

leaks, only use gas leak detecting solution or gas detecting instruments. Never use a match or open flame to locate gas leaks.

9.3.2 If a major leak is suspected, do not perform the above test. Call the LG&E Gas Emergency Service at

(502) 589-5511. 9.3.3 If you should shut off the service valve preceding the meter because of a suspected leak, do not turn it on

after the leak has been repaired. Notify LG&E. LG&E will confirm that the house line system is free from leaks and then turn on the gas.

9.4 Gas Consumption Test 9.4.1 To test the gas consumption and BTU input rate for a device, perform the following steps:

a. Turn off all appliances or devices not to be included in the test. For most accurate results, shut off their pilot lights.

b. Place the appliance to be tested into full operation. c. Observe the test dial. Using a stop watch or conventional watch, count the number of revolutions of

the test hand that occur in one minute, or time the number of seconds required for one or more complete revolutions.

d. Calculate the flow rate of gas using the following formula:

t

FNQ

3600

Where: Q = Flow rate of gas in cubic feet per hour (CFH)

N = Number of turns of the test hand F = Volume in cubic feet for one turn of the test hand (Most residential meters have a 1/2 cubic foot test dial.)

t = Measured time in seconds

Note: If the gas is being delivered at a pressure other than the standard pressure (i.e., 4 ounces), a multiplier must be applied. For assistance, consult the Gas Operations Center in your area.

e. To determine the BTUH input for the device being tested, multiply the above flow rate by one

thousand. While this value is an approximation, it is a conservative value because the BTU content for the natural gas delivered by LG&E is guaranteed to be a minimum of 1,000 BTU per standard cubic foot. Normally, the BTU content is slightly higher.

9.4.2 Upon completion of the test, return other appliances to normal operation.
