A. The U.S. Consumer Product Safety Commission encouragesinstallation of carbon monoxide alarms. There can be varioussources of carbon monoxide in a building or dwelling. Thesources could be gas-fired clothes dryers, gas cookingstoves, water heaters, furnaces, gas-fired fireplaces, woodfireplaces.

Carbon monoxide can cause serious bodily injury and/ordeath. Carbon monoxide or "CO" is a colorless and odorlessgas produced when fuel is not burned completely or when theflame does not receive sufficient oxygen.

a.

Therefore, to help alert people of potentially dangerous carbonmonoxide levels, you should have a commercially availablecarbon monoxide alarm that is listed by a nationallyrecognized testing agency in accordance with UnderwritersLaboratories Inc. Standard for Single and Multiple StationCarbon Monoxide Alarms, ANSl/UL 2034 or the CSA 6.19-01Residential Carbon Alarming Devices installed andmaintained in the building or dwelling concurrently with thegas-fired furnace installation (see Note below). The alarmshould be installed as recommended by the alarmmanufacturer's installation instructions.

There can be numerous sources of fire or smoke in a buildingor dwelling. Fire or smoke can cause serious bodily injury,death, and/or property damage. Therefore, in order to alertpeople of potentially dangerous fire or smoke, you should havefire extinguisher and smoke alarms listed by UnderwritersLaboratories installed and maintained in the building ordwelling (see Note below).

Note: The manufacturer of your furnace does not test any alarmsand makes no representations regarding any brand or typeof alarms.

FrozenWater Pipe Hazard

WATER DAMAGE TO PROPERTY HAZARD

Failure to follow this caution may result in propertydamage.Do not leave your home unattended for long periodsduring freezing weather without turning off watersupply and draining water pipes or otherwiseprotecting against the risk of frozen pipes andresultant damage.

Your furnace is designed solely to provide a safe and comfortableliving environment. The furnace is NOT designed to ensure thatwater pipes will not freeze. It is equipped with several safetydevices that are designed to turn the furnace off and prevent it fromrestarting in the event of various potentially unsafe conditions.

If your furnace remains off for an extended time, the pipes in yourhome could freeze and burst, resulting in serious water damage.

If the structure will be unattended during cold weather you shouldtake these precautions.

1. Turn off the water supply to the structure and drain the waterlines if possible and add an antifreeze for potable water todrain traps and toilet tanks. Open faucets in appropriateareas.

2.

3.

-or-

Have someone check the structure frequently during coldweather to make sure it is warm enough to prevent pipesfrom freezing. Instruct them on a service agency to call toprovide service, if required.

-or-

Install a reliable remote sensing device that wilt notifysomebody of freezing conditions within the home.

Winter Shutdown

If you go away during the winter months and do not leave the heaton in your home, the plastic transition box and the condensate trapon the furnace must be protected from freeze damage.(SeeFigure 11 trough Figure 20)

1. Disconnect the 5/8"(15.9mm) OD rubber hose from the ventdrain fitting that is located downstream of the combustionblower. Insert a funnel into the hose and pour four(4) ouncesof sanitary type (RV) antifreeze into the condensate trap.Reconnect the 5/8"(15.9mm) OD rubber hose to the stub onthe vent drain fitting. Secure with the hose clamp.

2. Disconnect the 3/4" (15.9mm)OD rubber hose from thecondensate trap. Insert a funnel into the hose and and pourfour(4) ounces of sanitary type (RV) antifreeze into theplastic Transition box. Squeeze the hose together near theend and quickly reconnect the 3/4" (19.1mm) OD rubberhose to the stub on the condensate trap. Secure with thehose clamp.

When you return home, your furnace will be ready to start, as it isnot necessary to drain the antifreeze from the furnace.

Use a raised base if the floor is damp or wet at times.

Residential garage installations require:

• Burners and ignition sources installed at least 18"(457.2mm) above the floor.

8.

9.

Furnace must be located or physically protected frompossible damage by a vehicle.

If the furnace is to be suspended from the floor joists in abasement or a crawl space or the rafters in an attic, it isnecessary to use steel pipe straps or an angle iron frame toattach the furnace. These straps should be attached to thefurnace with sheet metal screws and to the rafters or joistswith bolts. The preferred method is to use an angle iron framebolted to the rafters or joists.

Local codes may require a drain pan under the entire furnaceand condensate trap when the furnace is installed in atticapplication.

This furnace may be used for construction heat provided that allthe following conditions are met:

The furnace is permanently installed with all electricalwiring, piping, venting and ducting installed according tothese installation instructions. A return air duct is provided,sealed to the furnace casing, and terminated outside thespace containing the furnace. This prevents a negativepressure condition as created by the circulating air blower,causing a flame rollout and/or drawing combustion productsinto the structure.

• The furnace is controlled by a thermostat. It may not be "hotwired" to provide heat continuously to the structure withoutthermostatic control.

Clean outside air is provided for combustion. This is tominimize the corrosive effects of adhesives, sealers andother construction materials. It also prevents theentrainment of drywall dust into combustion air, which cancause fouling and plugging of furnace components.

The temperature of the return air to the furnace ismaintained between 55° F (13° C) and 80° F (27° C), with noevening setback or shutdown. The use of the furnace whilethe structure is under construction is deemed to beintermittent operation per our installation instructions.

The air temperature rise is within the rated rise range on thefurnace rating plate, and the firing rate has been set to therating plate value.

The filters used to clean the circulating air during theconstruction process must be either changed or thoroughlycleaned prior to occupancy.

The furnace, ductwork and filters are cleaned as necessaryto remove drywall dust and construction debris from allHVAC system components after construction is completed.

After construction is complete, verify furnace operatingconditions including ignition, input rate, temperature riseand venting according to these instructions.

IndoorCombustionAir standard method permits indoor air to be used for combustion andventilation air.


Failure to follow this warning could result inpersonal injury or death.Most homes will require additional air fromoutdoors for combustion and ventilation. A spacewith at least 50 cubic feet per 1,000 BTUH (4.8 cubicmeters per kW) input rating or homes with tightconstruction may need outdoor air, suppliedthrough ducts, to supplement air infiltration forproper combustion and ventilation of flue gases.

Standard and Known-Air-lnfiltrati0n Rate Methods© NFPA & AGA

Indoor air is permitted for combustion and ventilation, if theStandard or Known-Air-Infiltration Rate Method is used.

The Standard Method may be used, if the space has no lessvolume than 50 cubic feet per 1,000 BTUH (4.8 cubic meters perkW) input rating for all gas appliances installed in the space. The

The Known Air Infiltration Rate Method shall be used if the

infiltration rate is known to be less than 0.40 air changes per hour(ACH) and equal to or greater than 0.10 ACH. Infiltration ratesgreater than 0.60 ACH shall not be used. The minimum requiredvolume of the space varies with the number of ACH and shall bedetermined per Table 2 or Equations 1 and 2. Determine theminimum required volume for each appliance in the space, andadd the volumes together to get the total minimum requiredvolume for the space.



An unconfined space or homes with tightconstruction may not have adequate air infiltrationfor proper combustion and ventilation of flue gases.

Most homes will require additional air.

An attic or crawl space may be considered a space that freelycommunicates with the outdoors provided there are adequateventilation openings directly to outdoors. Openings MUSTremain open and NOT have any means of being closed off.Ventilation openings to outdoors MUST be at least 1 squareinch of free area per 4,000 BTUH (5.5 cm2/kW) of total inputrating for all gas appliances in the space.

In spaces that use the Indoor Combustion Air Method,infiltration should be adequate to provide air for combustion,ventilation and dilution of flue gases. However, in buildingswith unusually tight construction, additional air MUST beprovided using the methods described in section titledOutdoor Combustion Air Method:

* Unusually tight construction is defined as Construction with:

1. Walls and ceilings exposed to the outdoors have acontinuous, sealed vapor barrier. Openings aregasketed or sealed and

2. Doors and openable windows are weather stripped and

3. Other openings are caulked or sealed. These includejoints around window and door frames, between soleplates and floors, between wall-ceiling joints, betweenwall panels, at penetrations for plumbing, electrical andgas lines, etc.

VentilationAirSome provincial codes and local municipalities require ventilationor make-up air be brought into the conditioned space asreplacement air. Whichever method is used, the mixed return airtemperature across the heat exchanger MUST not fall below 60°so that flue gases wilt not condense excessively in the heatexchanger. Excessive condensation will shorten the life of the heatexchanger and possibly void your warranty.

Failure to follow this warning could result inpersonal injury or death.Use methods described here to provide combustionand ventilation air.

Single Pipe (N9MP1 Models)This furnace is certified as a Category _V appliance. This furnacerequires ventilation openings to provide air for proper combustionand ventilation of flue gases. All duct or openings for supplyingcombustion and ventilation air must comply with the gas codes orin absence of local codes, the applicable national codes.

When the installation is complete, see the "Venting andCombustion Air Check" in this manual.

Dual Certified (NgMP2,NgMPDand *gMPDModels)This furnace is certified as a Category _V appliance. This furnacecan be installed as a direct vent furnace using outside air forcombustion or the furnace can use air from inside the structure forcombustion. The INLET air pipe is optional. If combustion aircomes from inside the structure, adequate make up air MUST beprovided to compensate for oxygen burned. See Confined SpaceInstallation in the Combustion and Ventilation Air chapter. Ifcombustion air is drawn from outside the structure, it MUST betaken from the same atmospheric pressure zone as the vent pipe.

Contaminated Combustion Air

Installations in certain areas or types of structures will increase theexposure to chemicals or halogens that may harm the furnace.

The following areas or types of structures may contain or haveexposure to the substances listed below. The installation must beevaluated carefully as it may be necessary to provide outside airfor combustion.

• Commercial buildings.

• Buildings with indoor pools.

• Furnaces installed in laundry rooms.

• Furnaces installed in hobby or craft rooms.

• Furnaces installed near chemical storage areas.

• Permanent wave solutions for hair.

• Chlorinated waxes and cleaners.

NOTE: 1) In Canada, all pipe, fittings & cements must conform toapplicable CSA standards or to local codes having jurisdiction.

2) Only use solvent cements that are marked for use withthe specific venting material.

3) ABS to PVC transition joints REQUIRE a specialsolvent cement that meets the requirements of ASTM D3138.

4) Refer to ASTM D2855 for general procedure to use forcementing plastic pipe and fittings.

NOTE: In order to create a seal that allows future removal of pipe,RTV sealant MUST be used on the inlet pipe where it joins to thefurnace.

NOTE: All vent piping MUST be installed in compliance with localcodes or ordinances, these instructions, good trade practices, andcodes of country having jurisdiction.

1. Determine the best routing and termination for the vent pipeand air inlet pipe by referring to all of the instructions andguidelines in this Section.

2. Determine the size required for the vent pipe and air inletpipe.

3. Loosely assemble all venting parts without adhesive (pipejoint cement) for correct fit before final assembly.

4. Furnace shall be installed so as to prevent the accumulationof condensate.

5. Use of vertical piping is preferred because there will besome moisture in the flue gases that may condense as itleaves the vent pipe (See Instruction For Horizontal Vents).

6. The vertical vent pipe MUST be supported so that no weightis allowed to rest on the combustion blower.

7. Exhaust vent piping or air inlet piping diameter MUST NOTbe reduced.

8. All exhaust vent piping from the furnace to terminationMUST slope upwards. A minimum of 1/4" per foot per(6.4mm per 304.8mm) of run is required to properly returncondensate to the furnace drain system.

9. Use DWV type long radius elbows whenever possible, asthey provide for the minimum slope on horizontal runs andthey provide less resistance in the vent system. If DWVelbows cannot be used, use two, 45° elbows when possible.On horizontal runs the elbows can be slightly misaligned toprovide the correct slope.

10. All horizontal pipe runs MUST be supported at least everyfive feet with galvanized strap or other rust resistantmaterial. NO sags or dips are permitted.

14


44001 102404

11. All vertical pipe runs MUST be supported every six feet(1 .Sm) where accessible.

12. The minimum vent length is 5' (1.5m) of PVC.

13. The piping can be run in the same chase or adjacent tosupply or vent pipe for water supply or waste plumbing. Itcan also be run in the same chase with a vent from another90+ furnace.

NOTE: In NO case can the piping be run in a chase wheretemperatures can exceed 140 ° F(60°C). or where radiatedheat from adjacent surfaces would exceed 140° F(60°C).

14. The vent outlet MUST be installed to terminate in the sameatmospheric pressure zone as the combustion air inlet.

15. The vent system can be installed in an existing unusedchimney provided that:

* Both the exhaust vent and air intake run the length of thechimney.

* No other gas fired appliance or fireplace (solid fuel) isvented into the chimney.

* The top of the chimney MUST be sealed flush or crownedup to seal against rain or melting snow so ONLY the pipingprotrudes.

* The termination clearances shown in Figure 8 & Figure 9are maintained.

16. Furnace applications with vertical vents requiring ventdiameter increaser fittings must have increaser fittingsinstalled in vertical portion of the vent. Condensate will betrapped in the vent if the vent diameter is increased prior tohaving an elbow turned upward. This could cause nuisancetripping of the pressure switch.

Combustion Air and Vent Piping InsulationGuidelinesNOTE: Use closed cell, neoprene insulation or equivalent. IfFiberglass or equivalent insulation is used it must have a vaporbarrier. Use R values of 7 up to 10' (3.1m), R-11 if exposureexceeds 10'(3.1 m). If Fiberglass insulation is used, exterior to thestructure, the pipe MUST be boxed in and sealed againstmoisture.

1. When the vent or combustion air pipe height above the roofexceeds 30" (762mm) or if an exterior vertical riser is usedon a horizontal vent to get above snow levels, the exteriorportion MUST be insulated.

2. When combustion air inlet piping is installed above asuspended ceiling, the pipe MUST be insulated withmoisture resistant insulation such as Armafiex or otherequivalent type of insulation.

3. Insulate combustion air inlet piping when run in warm,humid spaces.

SizingCombustionAir andVent PipeConsult Table 3 or Table 4 to select the proper diameter exhaustand combustion air piping. Exhaust and combustion air piping issized for each furnace Btuh size based on total linear vent length(on inlet or outlet side), and number of 90 ° elbows required. Two45° elbows can be substituted for one 90 ° elbow. The elbow orelbows used for vent termination outside the structure ARE

counted, including elbows needed to bring termination aboveexpected snow levels. The elbow inside the furnace on theN9MPD and *9MPD IS NOT included in the count.

CondensateDrainTrapThis furnace removes both sensible and latent heat from the

products of combustion. Removal of the latent heat results incondensation of the water vapor. The condensate is removed fromthe furnace through the drains in the plastic transition and the ventfitting. The drains connect to the externally mounted condensatedrain trap on the left or right side of the furnace.

The startup of a new furnace will involve a cycle or two of thefurnace to properly prime the condensate trap with water. Until thetrap is fully primed, some condensate wilt be pulled into thecombustion blower. The furnace may cycle on the pressure switchconnected to the plastic transition box due to condensate buildup.After the trap is primed, the condensate will start draining from thefurnace. The combustion blower will clear out any remainingcondensate in the blower housing through the vent fittingdownstream of the blower. Note that the condensate trap can alsobe primed by pouring water into the 1/2" (12.7mm) drain hose.Remove the1/2 " (12.7mm) ID drain hose from either the gutter orthe white PVC tee trap. Using a funnel pour eight (8) ounces (236ml) of water into 1/2" (12.7mm) ID drain hose. Water will flowthrough the drain hose and into the condensate drain trap. This willprime both the vent and the transition sides of the trap. Reconnectthe 1/2" (12.7mm) ID drain hose to the original component, eitherthe gutter or the PVC tee trap.

The condensate drain trap supplied with the furnace MUST beused. The drain connection on the condensate drain trap is sizedfor 3/4" (19.1mm) PVC or CPVC pipe, however alternate 1/2"(12.7mm) CPVC [nominal 5/8" (15.gmm) O.D.] or vinyl tubing witha minimum inner diameter (I.D.) of 5/8" (15.9mm) may also beused, as allowed by local codes. Alternate drain pipes and hosesmay be used as allowed by local codes.

The drain line must maintain a 1/4" (6.4mm) per foot downwardslope toward the drain. 1/4" (6.4mm) per foot is recommended.Installation of an overflow line is recommended when the 1/4"(6.4mm) per foot slope to the condensate drain cannot bemaintained. A drain tube retainer clip is included in the furnace toprevent kinking/buckling of the drain tube. The retainer clip shouldremain in the furnace (between the door switch plate and theblower shelf, Figure 10) during operation. See Figure 20 forproper routing and installation of the overflow.

Drain Tube Retainer Clip Location

DrainTube

BloweDoorrShelfSw,,oh

Representative drawing only, some models may vary in appearance.

DO NOT trap the drain line in any other location than at thecondensate drain trap supplied with the furnace.

FROZEN AND BURST WATER PIPE HAZARD

Failure to follow this caution may result in propertydamage.If a condensate pump is installed, a pluggedcondensate drain or a failed pump may cause thefurnace to shut down. Do not leave the homeunattended during freezing weather without turningoff water supply and draining water pipes orotherwise protecting against the risk of frozen pipes.

If possible, DO NOT route the drain line where it may freeze. Thedrain line must terminate at an inside drain to prevent freezing ofthe condensate and possible property damage.

1. A condensate sump pump MUST be used if required bylocal codes, or if no indoor floor drain is available. Thecondensate pump must be approved for use with acidiccondensate.

2. A plugged condensate drain line or a failed condensatepump will atlowcondensate to spill. If the furnace is installedwhere a condensate spill could cause damage, it isrecommended that an auxiliary safety switch be installed toprevent operation of the equipment in the event of pumpfailure or plugged drain line. If used, an auxiliary safetyswitch should be installed in the R circuit (low voltage)ONLY.

3. If the auxiliary switch in the condensate pump is used, thefurnace may shut down due to a blocked condensate line orfailed pump. To prevent frozen water pipes see the "FrozenWater Pipe Hazard" section in this manual.

CondensateDrainTrap FreezeProtectionSpecial precautions MUST be made if installing furnace in an areawhich may drop below freezing. This can cause improperoperation or damage to the equipment. If the the furnaceenvironment has the potential of freezing, the drain trap and drainline must be protected. Use 3 to 6 watt per foot at 115 volt, 40 ° F(4°C) self-regulating shielded and waterproof heat tape. Wrap thedrain trap and drain line with the heat tape and secure with the ties.Follow the heat tape manufacturer's recommendations.
