I. VENTILATION

The area in which the heating system is locatedmust have an adequate supply of air for bothcombustion and draft diverter dilution. Openbasements and below grade utility rooms or crawlspaces without storm windows or tight doors willgenerally permit adequate air infiltration.

if the heating system is located in a separate roomwith a tight door, ventilation must be provided to anopen area within the building or to the outside. Ifthe openings are within the building two open grillsmust be installed, one near the floor and one closeto the ceiling. The open (non-adjustable) grillsmust have a free area of at least one square inch(6.45cm) per 1,000 BTU of burner input.If the building is of unusually tight construction orhas a large exhaust fan installed, on a basement,crawl space or slab construction home, provisionsmust be made for an outside air supply that isducted into the furnace room. It must have apermanent (non-adjustable) opening of at least onesquare inch (6.45cm) of free area per 1,000 BTUinput. Consult the National Fuel Gas Code latestedition, or the CAN/CGA-B149 Installation Codes,for more detailed information.

With direct spark ignition system the burnerperforms well under slight or momentary back draftconditions. However, it is not intended foroperation under sustained reverse draft conditions.This condition is fairly common in buildings withlarge ventilating fans. The fans can create a sub-atmospheric pressure in the building causing adown draft in the chimney. This will causehazardous flue gas products to be drawn into thebuilding from the draft diverter. The conditionsmust be corrected promptly.

II. PREPARATION OF THE HEATINGAPPLIANCE

The heating appliance must be in good repairand have adequate capacity to heat thestructure.

Keep all materials, combustible or otherwise, atleast two feet (.61m) from the heating appliance.

Thoroughly clean the heat exchanger andinspect for cracks or other defects - the installermust determine if the appliance is safe toupgrade.

The combustion chamber must be free fromdeterioration and adequately sized.

Stainless steel chambers must be lined withceramic fiber material to prevent deterioration.

Coal Fired Units

To convert an appliance that was coal fired, thefollowing consideration need to be observed:

Select feed door or ash-pit door for burnermounting.

Ash-pit: Remove grates and install combustionchamber.

Feed Door: Fill bottom with suitable material(vertniculite, etc.), secure door.

Warm Air Furnaces

If combustion chamber upgrade is necessary,do not reduce the original height or outletconfiguration.

Boilers, Cast Iron & Steel, Steam or Hot Water

Inspect for leaks and repair any that are found.Check the ceramic or fire brick combustionchambers. Replace if not in good condition.NOTE - Do not remove the chamber from a drybase boiler. Clean the gauge glass on steamboilers so that all safety devices and controls areoperating according to the manufacturer'sspecifications.

NOTE - If the flue pipe length exceeds 10' (3.04m)or contains more than two elbows, use the nextsize larger flue pipe and draft diverter.

NOTE - Any reduction in the flue pipe diametermust be made at healing appliance flue outlet byuse of a fixed collar reducer. Flue pipe must be 24aa. or heavier steel.

NOTE - Where local codes permit, install a doubleacting barometric damper, rather than a draftdiverter. Less heated air is lost up the chimneywith a barometric damper than with a draft diverter.

WARNING: SPILL SWITCH

A device which will automatically shut off gas to theburner in the event of sustained backdraft isrequired. It shall be of the listed manual reset typeand installed and adjusted by a qualified servicetechnician in accordance with the manufacturer'sinstructions.

Method 2 - Same diameter pipe as the applianceflue collar and a neutral pressure adjuster. Ifdiameter of the flue pipe is greater than thediameters shown in Method 1 a neutral pressurepoint adjuster shall be installed between the fluecollar of the appliance and the relief opening of thedraft diverter. It shall be constructed so that it ispermanently locked in the adjusted position andcannot be changed accidently in a manner that willinterfere with the normal operation of the burner.5

Raure 2 illustrates a suggested method forconstructing this device. The neutral pressurepoint adjuster shall then be left in the fully openposition until after the burner rating has beenestablished.Figure 2

Remove adjuster, trimoff excess, slitremainder vertically.Bend segments inalternate directions.

Replace in flue pipe,recheck adjustments toascertain unchangedconditions. Fastenadjuster in place withsheet metal screws.

Scribe linearoundflue pipe.

^Trim off excess stock.

- Scribe lines.

No manually adjusted flue pipe damper shall be in-stalled on any Gas Conversion Installation. Thehorizontal run of flue pipe shall be pitched upward1/4" (.64cm) per foot or more. Number of elbowsmust be kept to a minimum to avoid excessiveresistance to flue gas flow. Secure all joints withsheet metal screws to avoid sagging or dis-placement. The flue pipe must be spaced at least6" (14.2cm) from combustible materials, 12"(30.5cm) if uninsulated. Flue pipe must be firmlycemented into the chimney opening. It must notextend beyond the inner wall. Where two or moreappliances use the same chimney, be sure not toenter the chimney with both flues at the same level.Under no circumstances should the flue pipe beconnected to the flue of any open fireplace. A draftDiverter must be CSA Certified (or one approvedby the local gas company) and installed in the fluepipe. The draft diverler should be the same size asthe flue pipe and located higher than the highestpart of the heating appliance.

Vertical draft diverters should have two flue pipediameters between the skirt and any surface underit. This distance may be reduced to one diameteron the horizontal or horizontal to vertical diverters.

Where the flue pipe passes through a combustiblepartition a ventilated thimble must be used. Thedraft diverter must be located in the same room asthe heating appliance.

On forced warm air furnaces where the flue outletis located on the suction side if the circulating airblower, make certain the flue pipe connection isfully sealed to prevent flue products from beingdrawn into the circulating air.

IV. CHIMNEYS

The chimney height is determined by the buildingroof line and surrounding trees and buildings. Itshould be at least two feet (5.1cm) higher than theroof ridge with no obstructions from adjacent treesand buildings. When two flues enter the samechimney, it is recommended that the higher BTUinput appliance flue enter at a lower point.

The internal construction of the chimney should becorrosion resistant tile, stainless steel or someother material that will withstand flue gas products.If the chimney is unlined, consult the local gascompany for their recommendations. Refer tofigure 4 on page 8 for chimney instructions.

Many prefabricated chimneys on either slabconstruction or basement homes, terminate nearthe ceiling level. During rainstorms it is commonfor water to run down the heating appliance fluepipe. Many warm air heating appliances have aflue outlet directly above the burner. There isalways a possibility that the water from the fluepipe will drain out upon the burner and its controls.This condition must be corrected by installing a capor rain shield on top of the chimney.

V. ELECTRICAL

All wiring should conform to the National ElectricalCode ANSI/NFPA 70 or, the Canadian ElectricalCode CSA C22.1, or the legally authorized code inyour area. Use multiple conductor wiring notlighter than 14 gauge for line voltage wiring. Theconversion burner must be grounded. A groundterminal is provided in the 4 x 4 (10.2cm x 10.2cm)field wiring box, maximum amperage draw 5.7amperes. See figure 5 on page 9 for wiringdiagram.

If an external electrical source is utilized, theconversion burner, when installed, must beelectrically grounded in accordance with localcodes or, in the absence of local codes, with theNational Electrical Code, ANSI/NFPA 70, or theCanadian Electrical code, CSA C22.1.

CAUTION: Label all wires prior to disconnectionwhen servicing controls. Wiring errors can causeimproper and dangerous operation.Verify proper operation after servicing.

Each burner has its own 30VA, 24 volt controltransformer. Under no circumstances should anyother electrical equipment be operated from thistransformer.

Locate the thermostat where it will sense thenatural air circulation within the building. Do notplace it in a location where it will be subjected tocold drafts from doors or windows or where it cansense the warm air from registers or radiators. It isnot recommended that a thermostat be installed onan outside wall, in front of a fireplace or at the baseof an open stairwell.

In addition to the thermostat each installation mustinclude an operating and/or high limit control asshown in the wiring diagram

NOTE: When the thermostat wires terminate onthe G2 primary control box'T1 terminals, the heatanticipator setting for the G2 burners is determinedby adding the primary control current 1o the gasvalve current. The result is the anticipator setting.(Example: .2 + .6 = .8 amps.)

If the thermostat wires are not terminated on theburner box "T" terminals, and these terminals areJUMPERED, you must then determine what thecontrolling device at the point where the thermostatwires terminate. Typically, this information can befound on the body or cover of the controllingdevice.

When the current draw cannot be determinedaccurately by the above method, measure thecurrent with an ampere meter using the 1 AMPscale. Connect the meter leads in series with oneof the thermostat-leads for the accurate reading.

Steam and vapor systems must also be protectedwith a low water cutoff to prevent firing a dry boiler.

The pipe diameter may be reduced one size if LPGgas is used. Use steel pipe and Malleable ironfittings for gas service lines. Provide rigid supportsfor the pipe. If the pipe size must be reduced usereducing couplings only. Avoid the use of reducingbushings. Remove all burrs and inspect the pipefor dirt or other foreign material.

A main manual gas cock is to be installedapproximately 5' (1.5m) above the floor level. A teeis located on the vertical drop at an appropriatelevel to attach the burner gas valve. The gas lineextends down to the floor with a cap on the end.This extension provides the required drip leg. Seefigure 6. If the gas pipe passes through a jacketedenclosure the union must be located inside thejacket so that the burner can be removed forservice. The manual gas cock is located outsidethe jacket. The gas valve used on all G2 burnershave a main line pressure tap on the inlet side ofthe gas valve.

Figure 6MAIN SHUT-OFF VALVE

( BY INSTALLER)

Piping must comply with local codes. When pipingLPG burners use pipe joint compound that isresistant to LP gas.

The appliance and its individual shutoff valve mustbe disconnected from the gas supply piping systemduring any pressure testing of that system at testpressures in excess of 1/2 PSIG (3.45kPa).

The appliance must be isolated from the gassupply piping system by closing its individualmanual shutoff valve during any pressure testing ofthe gas supply piping at tests pressures equal to orless than 1/2 PSIG (3.45kPa).A 1/8-inch (.32cm) NIPT plugged tapping,accessible for test gage connection, must beprovided immediately upstream of the gas supplyconnection to the conversion burner.

WARNING: Explosion Hazard! The control canmalfunction if it gets wet. Never try to use one thathas beenwet - replace it.

Never use a match or open flame for leakdetection. Use only soap solution.

VII. GAS ORIFICE SIZING AND BURNER HEADSELECTION

The gas input rate should be set to the rate deter-mined by the building heat loss calculations or bythe heating appliance labeled input rating. Do notexceed the maximum input of the heating applianceor the burner head firing range.

The input rate and the type of gas to be used mustbe determined by the installer. Once this has beendetermined, the proper burner head and orifice canbe obtained from your Adams distributor.Whenever the precise orifice is not known at thetime of purchase, the burner will be equipped andtested at the factory to fire natural gas at theminimum input range of the installed burner head.On the opposite end of the orifice spring inside thegas manifold will be the orifice that delivers theminimum rate for LP gas with the burner headselected. See figure 8 page 14 for installationdetails. The orifice that is inserted into themanifold first is the one that determines the inputrate with the gas being used.

The burner is designed for use with either Naturalor LP gases at 3.5" W.C. (.87kPa) manifoldpressure. The only burner adjustment that isrequired, in order to convert from one type of gasto the other, is the selection of the proper orifice forthe burner head range and the type of gas beingused. The following charts outline the head firingranges and orifice rates in thousands of BTU's perhour for the respective gas types at 3.5" W.C.(.87kPa) manifold pressure.

The inside diameter of the orifice can be enlargedwith a taper reamer to obtain a higher rate withinthe burner head firing range, or the desired orificecan be obtained from your Adams distributor.

All orifice sizes in the chart are approximate, theactual burner input rate will vary slightly with localheating values supplied. It is recommended thatinquiry be made of the gas supplier for the correctheating value. The actual firing rate can then bedetermined by following the instructions outlined inSection IX item 11.

VIII. ORIFICE CHANGE OUT PROCEDURE

It is not necessary to disassemble the burner tochange gas orifices. Figure 8 shows a detailedview of the change procedure. Simply remove theorifice cap and install the proper primary orifice onthe spring. Insert the spring assembly into themanifold and tighten the orifice cap. Do not over-tighten.

IX. INITIAL START UP AND ADJUSTMENT

1. Check aHjojQts for gas leaks. ReferenceSection IV Gas Piping for suggested methods.

NOTE: Care must be taken to prevent wetting theelectronic components during the leak test.

WARNING: Explosion Hazard! The control canmalfunction if it gets wet. Never try to use one thathas been wet - replace it.

2. It is important to purge the gas line on longsupply lines. Loosen the union figure 6 on page 10and allow the air to escape into the atmosphereuntil the gas starts flowing, then tighten the union.CAUTION - Purging excessive amounts of gas intothe atmosphere can be dangerous, particularly withLPG, which is heavier than air.

3. Apply a few drops of #20 SAE Oil to the motorbearings.

4. Make certain that the gas valve dial is turned toon. Air band if used should be set at zero and airshutter open to position 2 or less.

5. Turn on the burner power supply switch and setthe room thermostat above room temperature. Letthe burner run until flame is established or thecontrol locks out (45 seconds).

14

6. If the control locks out turn the main line powersupply switch off and back on. This action resetsthe control and another purge cycle can beperformed if desired.

7. Burner should now light off if gas line has beenpurged. NOTE: There is a 4 second trial forignition. If burner does not light off reset thecontrol by repeating step # 6.

8. The gas input for natural gas can be determinedby timing the gas meter. To vary the gas inputinstall the nearest size orifice then adjust thepressure regulator up or down for exact inputdesired. The manifold pressure is to be measuredat the pressure tap on the gas valve. NOTE: Donot exceed the gas valve manufacturersrecommended pressure adjustment range.9. Adjust the combustion air shutters (when required) until good combustion is obtained.NOTE: Always use combustion test equipmentwhen setting the burner. It is impossible tooptimized combustion with the "eyeball" method.Check the CO2 and the CO with instruments inorder to obtain the following recommended values:

After the final air adjustment is made lock thesettings to prevent tampering.

10. Gross Flue Gas Temperatures: 350F (175C)minimum for an outside chimney with threeexposed walls. 300F (147C) minimum for achimney centrally located within the structure. Ifthe gross stack temperatures exceeds 550F(285C) to 600F (312C) the appliance may beover-fired or the heat exchanger surfaces may bepartially blocked. Recheck the input and inspectthe appliance.

NOTE: Make certain all other gas appliances inthe home are turned off before clocking the gasmeter.

11. To determine the firing rate accurately,measure the time required for 1 cu. ft. of gas to be

consumed. Use the following formula to calculateBTU/HR input.

3600 X BTU/Cu. Ft. * No. seconds for 1 cu. ft. =BTU/Hr.

EXAMPLE: 3600 X 1000 - 20 = 180,000 BTU/Hr.(Nat. Gas)For subsequent normal starting and shutdownprocedure refer to instruction plate mounted on theburner.

X. BURNER CONTROL SYSTEM SEQUENCEOF OPERATION

1. Thermostat contacts close.

2. Step down transformer (120V to 24V) energizescoil in motor relay and motor starts.

3 When motor approaches full RPM, thecentrifugal switch contacts on the motor closesupplying 24 volts to the primary control.

4. After 45 seconds time delay 20 or more voltsare supplied to the primary control.

5. The contacts in relay, close supplying 120 voltsto the Ignition Transformer.

6. Arc is immediately established and 20 or morevolts supplied to the gas valve

7. The gas valve opens and flame is immediatelyestablished.

8. As soon as flame is established and 3 or moremicroamp signal is sent back to the PrimaryControl, the ignition relay drops out killing theignition arc. If the flame cannot be proven by thesignal strength in 4 seconds the control goes tolock out and turns both the ignition and gas valveoff. The burner motor will continue to operateduring lockout, if the thermostat or controllingcircuit is calling for burner operation.

15

9. The primary control is reset by either turning offthe power to the burner or turning down thethermostat below room temperature and resetting itback again above room temperature.

10. If during a firing cycle the burner loses flamefor any reason, other than power failure, theignition arc is re-established in 0.8 seconds or lessand the 4 second trial for ignition is initiated.

XI. THE GAS VALVE MOUNTING ASSEMBLY

The gas valve mounting plate assembly includesthe combination gas valve, gas manifold, eductortube and the valve mounting plate. This assemblyis removed as a unit by removing four screw in themounting plate and withdrawing the assembly fromthe blower housing. The 24 volt combination gasvalve serves these functions; manual main gasshutoff, main gas pressure regulation, automaticelectric gas shutoff. A redundant gas valve hastwo automatic electric gas shut off valves in thesame body for additional safety. The automaticshut off function is controlled by the motor relaywhich switches power through the motor centrifugalswitch.

NOTE: If it is necessary to replace a defective gasvalve, it can be done with a Honeywell 24 voltvalve. This valve is available with either a fast orstep opening regulation. DO NOT replace with aslow opening valve. Make sure that thereplacement valve is designed for use with DirectSpark Ignition Systems.

If the gas line pressure to the burner exceeds themaximum rated inlet pressure of 13" W.C. (3.2kPa), install an axillary gas pressure regulator,rated for main burner service, ahead of the gasvalve on the burner. Reduce the incoming gaspressure to between 5" W.C. (1.2kPa) to 10" W.C.(2.5kPa) for natural gas and 11" W.C. (2.7kPa) to13" W.C. (3.2kPa) for LPG.

The gas valve regulator is factory set for 3.5" W.C.(.87kPa) manifold pressure. If the rate must beslightly adjusted, remove the regulator cap and turnthe screw either clockwise or counterclockwise toincrease or decrease the manifold pressure notmore than +/- 0.3" W.C. (.07kPa).

When the gas valve mounting plate assembly isremoved from the housing during servicing, caremust be taken to relocate the "Z" dimension. Thisis accomplished by aligning the arrow on theaffixed label to the "Z" locator notch cut in the gasmounting plate, as outline in figure 9.

The "Z" dimension is determined by removing theburner head assembly and measuring the distancefrom the eductor tube to the face of the air tube.This should be 1.5" (3.81cm).

Figure 9

1.5-(3.W:M> -IV DIMENSIONBURNHWHHEADREMOVED

NOTE: When reinstalling the gas valve mountingplate assembly, be sure to insert the eductor tubeinto the centering ring located in the air tube. Thiscan be easily accomplished by looking under therear edge of the mounting late. You can observethe entry of the eductor tube into the centering ring.

XII. THE BLOWER MOTOR ASSEMBLY

The blower motor assembly includes the motor andthe blower wheel.

Occasional cleaning of the blower wheel and inletair damper may be required. Accumulation of lintand dirt around the shutters and band mayindicated cleaning is necessary. The appearanceof the flame can also indicate a lack of combustion

If the motor fails to operate, first check the motorrelay and determine if it is functioning and thatelectrical power is available to the motor beforedetermining the motor is defective.

BURNER CYCLES ERRATICALLY

1. Check for proper thermostat installation and location.

2. Check thermostat heat anticipator for correct setting.

3. Check low voltage circuit for bad wiring, electricalconnections and/or switches.

4. Check line voltage circuit for bad wiring, electricalconnections and/or switches.

NOTE: When the thermostat wires terminate onthe G2 primary control box "T" terminal, the heatanticipator setting value for the G2 burner isdetermined by adding the primary control current tothe gas valve current. The result is the anticipatorsetting. (Example: .2 + .6 = .8 amps.)

Set anticipator to correct value if adjustable type. Ifproper setting cannot be made, replace with compatiblethermostat.

If the thermostat wires are not terminated on theburner control box "T1 terminals, and theseterminals are JUMPERED, you must thendetermine what the correct anticipator setting is byinspecting the controlling device at the point wherethe thermostat wires terminate. Typically, this in-formation can be found on the body or cover of thecontrolling device.

When the current draw cannot be determinedaccurately by the above method, measure thecurrent with an ampere meter using the 1 ampscale. Connect the meter leads in series with oneof the thermostat leads for the accurate reading.
