1. Safe Installation Requirements

FIRE, EXPLOSION, AND ASPHIXlATION HAZARD Improper adjustment, alteration, service,

maintanence or installation could cause serious injury, death and/or property damage.

Installation or repairs made by unqualified persons could result in hazards to you and others.

Installation MUST conform with local codes or, in the absence of local codes, with codes of all

governmental authorities having,jurisdiction. The information contained in this manual is intended for use by a qualified service agency that

is experienced in such work, is familiar with all precautions and safety procedures required in

such work, and is equipped with the proper tools and test instruments.

• This furnace is NOT approved for installation in mo- bile homes, trailers or recreation vehicles.

• Seal around supply and return air ducts.

• Install correct filter type and size.

• Unit MUST be installed so electrical components are pro- tected from direct contact with water.

Safety Rules

Your unit is built to provide many years of safe and dependable service providing it is properly installed and maintained. However,

abuse and/or improper use can shorten the life of the unit and create hazards for you, the owner.

The U.S. Consumer Product Safety Commission encourages installation of carbon monoxide alarms. There can be various

sources of carbon monoxide in a building or dwelling. The sources could be gas-fired clothes dryers, gas cooking

stoves, water heaters, furnaces, gas-fired fireplaces, wood fireplaces, and several other items.

NOTE: This furnace is design-certified by the CSA International (formerly AGA and CGA) for installation in the United States and

Canada. Refer to the appropriate codes, along with this manual, for proper installation.

• Use only the Type of gas approved for this furnace (see Rating Plate on unit). Overfiring will result in failure of heat

exchanger and cause dangerous operation. (Furnaces can be converted to L.P. gas with approved kit.)

• Install this furnace only in a location and position as speci- fied in "2. Installation"of these instructions.

• Provide adequate combustion and ventilation air to the fur- nace as specified in "3. Combustion and Ventilation Air" of

these instructions. Combustion products must be discharged outdoors. Con-

nect this furnace to an approved vent system only, as spe- cified in "4. Vent and Combustion Air Piping" of these

instructions. Never test for gas leaks with an open flame. Use a com-

mercially available soap solution made specifically for the detection of leaks to check all connections, as specified in "6. Gas Supply and Piping, Final Check"of these instruc-

tions. Always install furnace to operate within the furnace's in-

tended temperature-rise range with a duct system which has an external static pressure within the allowable range, as specified in "Technical Support Manual" of these in-

structions.

• When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space con- taining the furnace, the return air shall also be handled by a duct(s) sealed to the furnace casing and terminating out- side the space containing the furnace.

• A gas-fired furnace for installation in a residential garage must be installed as specified in "2. Installation"of these

instructions.

• This furnace is not to be used for temporary heating of buildings or structures under construction.

Carbon monoxide can cause serious bodily injury and/or death. Carbon monoxide or "CO" is a colorless and odorless

gas produced when fuel is not burned completely or when the flame does not receive sufficient oxygen.

Therefore, to help alert people of potentially dangerous ca rbon monoxide levels, you should have a commercially available carbon monoxide alarm that is listed by a nationally recog- nized testing agency in accordance with Underwriters Labora-

tories Inc. Standard for Single and Multiple Station Carbon Monoxide Alarms, ANSI/UL 2034 or the CSA 6.19-01 Resi-

dential Carbon Alarming Devices installed and maintained in the building or dwelling concurrently with the gas- fired furnace

installation (see Note below). The alarm should be installed as recommended by the alarm manufacturer's installation in-

structions.

There can be numerous sources of fire or smoke in a building or dwelling. Fire or smoke can cause serious bodily injury, death, and/or property damage. Therefore, in order to alert people of potentially dangerous fire or smoke, you should have

fire extinguisher and smoke alarms listed by Underwriters Lab- oratories installed and maintained in the building or dwelling

(see Note below).

Note: The manufacturer of your furnace does not test any alarms

and makes no representations regarding any brand or type of alarms.

To ensure safe and efficient operation of your unit, you should do the following:

Thoroughly read this manual and labels on the unit. This

will help you understand howyour unit operates and the haz-

ards involved with gas and electricity. Do not use this unit if any part has been under water. Im-

mediately call a qualified service technician to inspect the unit and to replace any part of the control system and any gas con-

trol which has been under water.

3. Never obstruct the vent grilles, or any ducts that provide air to the unit. Air must be provided for proper combustion and ventilation of flue gases.

FrozenWater PipeHazard

WATER DAMAGE TO PROPERTY HAZARD

Failure to protect against the risk of freezing could result in property damage and/or personal injury.

Do not leave your home unattended for long periods during freezing weather without turning off water

supply and draining water pipes or otherwise protecting against the risk of frozen pipes and resultant damage.

Your furnace is designed solely to provide a safe and comfortable living environment. The furnace is NOT designed to ensure that

water pipes will not freeze. It is equipped with several safety de- vices that are designed to turn the furnace off and prevent it from restarting in the event of various potentially unsafe conditions.

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

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

1. Turn off the water supply to the structure and drain the water lines if possible and add an antifreeze for potable water to

drain traps and toilet tanks. Open faucets in appropriate areas.

-or-

Have someone check the structure frequently during cold weather to make sure it is warm enough to prevent pipes from freezing. Instruct them on a service agency to call to provide service, if required.

-or-

3. Install a reliable remote sensing device that will notify some- body of freezing conditions within the home.

Winter Shutdown

If you go away during the winter months and do not leave the heat on in your home, the plastic transition box and the condensate trap on the furnace must be protected from freeze damage.(See Figure 9 trough Figure 18)

1. Disconnect the 5/8" OD rubber hose from the vent drain fit- ting that is located downstream of the combustion blower. Insert a funnel into the hose and pour four(4) ounces of sani- tary type (RV) antifreeze into the condensate trap. Recon- nect the 5/8" OD rubber hose to the stub on the vent drain

fitting. Secure with the hose clamp.

2. Disconnect the 3/4" OD rubber hose from the condensate trap. Insert a funnel into the hose and and pour four(4)

ounces of sanitary type (RV) antifreeze into the plastic Tran- sition box. Squeeze the hose together near the end and quickly reconnect the 3/4" OD rubber hose to the stub on the condensate trap. Secure with the hose clamp.

When you return home, your furnace will be ready to start, as it is not necessary to drain the antifreeze from the furnace.

2. Installation

CARBON MONOXIDE POISONING HAZARD Failure to properly vent this furnace or other

appliances could result in death, personal injury and/or property damage.

This furnace can NOT be common vented or connected to any type B, BW or L vent or vent

connector, nor to any portion of a factory-built or masonry chimney. If this furnace is replacing a

3reviously common-vented furnace, it may be

necessary to resize the existing vent and chimney to

3revent oversizing problems for the other

remaining appliance(s). See Venting and Combus- tion Air Check in Gas Vent Installation section. This

furnace MUST be vented to the outside.

Location and Clearances

Refer to Figure 1 or Figure 2 for typical installation and ba- sic connecting parts required. Refer to Figure 4 for typical horizontal direct vent installation and basic connecting parts required. Supply and return air plenums and duct are also required.

If furnace is a replacement, it is usually best to install the fur- nace where the old one was. Choose the location or evalu-

ate the existing location based upon the minimum clearance and furnace dimensions (Figure 3).

FROZEN AND BURST WATER PIPE HAZARD

Failure to protect against the risk of freezing could result in property damage and/or personal injury.

Special precautions MUST be made if installing furnace in an area which may drop below freezing. This can cause improper operation or damage to

equipment. If furnace environment has the potential

of freezing, the drain trap and drainline must be

protected. The use of electric heat tape or RV

antifreeze is recommended for these installations.

(See "Condensate Trap Freeze Protection Section")

Do NOT operate furnace in a corrosive atmosphere containing chlorine, fluorine or any other damaging chemicals. Refer to Combustion & Ventilation Air section,

Installation Requirements

1. Install furnace level.

2. This furnace is NOT to be used for temporary heat of buildings or structures under construction.

3. Install the vent pipes as short as practical. (See Gas Vent Installation section).

4. Do NOT install furnace directly on carpeting, tile or other com- bustible material other than wood flooring.

5. Maintain clearance for fire safety and servicing. A front clear- ance of 30" is minimum for access to the burner, controls and

filter. See clearance requirements in Figure 3 or.

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

7. Residential garage installations require:

• Burners and ignition sources installed at least 18" (457 mm) above the floor.

Furnace must be located or physically protected from pos- sible damage by a vehicle.

If the furnace is to be suspended from the floor joists in a base- ment or a crawl space or the rafters in an attic, it is necessary to use steel pipe straps or an angle iron frame to attach the furnace. These straps should be attached to the furnace with sheet metal screws and to the rafters or joists with bolts. The

preferred method is to use an angle iron frame bolted to the rafters or joists.

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

The furnace is permanently installed with all electrical wir- ing, piping, venting and ducting installed according to these

installation instructions. A return air duct is provided, sealed

to the furnace casing, and terminated outside the space

containing the furnace. This prevents a negative pressure condition as created by the circulating air blower, causing a flame rollout and/or drawing combustion products into the

structure.

• The furnace is controlled by a thermostat. It may not be "hot

wired" to provide heat continuously to the structure without thermostatic control.

Clean outside air is provided for combustion. This is to mini- mize the corrosive effects of adhesives, sealers and other construction materials. It also prevents the entrainment of drywall dust into combustion air, which can cause fouling and plugging of furnace components.

CARBON MONOXIDE POISONING HAZARD. Failure to follow safety warnings exactly could

result in serious injury, death, or property damage. Do NOT operate furnace in a corrosive atmosphere

containing chlorine, fluorine or any other damaging chemicals, which could shorten furnace life.

Refer to 3. Combustion & Ventilation Air section,

I • The temperature of the return air to the furnace must be

back or shutdown. The use of the furnace while the struc-

ture is under construction is deemed to be intermittent

operation per our installation instructions. The air temperature rise is within the rated rise range on the

furnace rating plate, and the firing rate has been set to the rating plate value.

The filters used to clean the circulating air during the construction process must be either changed or thoroughly cleaned prior to occupancy.

The furnace, ductwork and filters are cleaned as necessary

to remove drywall dust and construction debris from all

HVAC system components after construction is completed.

Installation Positions

This furnace can be installed in an upflow, horizontal (either left or right) or downflow airflow position. DO NOT install this furnace on its back. For the upflow position, the return air ductwork can be at-

tached to either the left or right side panel and/or the bottom. For horizontal and downflow positions, the return air ductwork must be attached to the bottom. The return air ductwork must never be at-

tached to the back of the furnace.

Furnace Installation Considerations

The installation of the furnace for a given application will dictate the position of the furnace, the airflow, ductwork connections, vent and combustion air piping. Consideration must be given to the follow- ing:

Condensate Trap and Drain Lines

The supplied condensate trap must be attached to the furnace side panel on either the left or right side. For horizontal installa- tions, the drain trap is vertically attached to the side panel below

the furnace. A minimum clearance of 6" below the furnace is re- quired for the condensate trap. Downward slope of the conden-

sate drain line from the condensate trap to the drain location must be provided. Adequate freeze protection of the drain trap and the drain line must be provided. See "Condensate Drain Trap"section

for further details.

Leveling

Proper leveling of the furnace must be provided to insure proper drainage of the condensate from the furnace. The furnace must be

level to within /4' from front to back and from side to side for upflow and downflow installations or top to bottom for horizontal installa- tions.

Vent and Combustion Air Connections

On the Dual Certified furnace, the vent and combustion air pipes attach to the furnace through the top panel for the upflow and hori-

zontal installations. For the downflow installation, the vent and combustion air pipes attach to the furnace through the alternate

locations on the furnace side panels. Note: On the Direct Vent furnace, the vent pipe attaches to the fur-

nace through the side panels. The combustion air pipe attaches to the top panel or to the alternate location on the side panel.

On the Single Pipe furnace, the vent pipe attaches to the furnace through the furnace side panels.

Note: Repositioning of the combustion blower is required for the vent pipe connection to the furnace through the "right side" panel. See "Vent and Combustion Air Piping"section for further details.

Horizontal Furnace Installation

This furnace can be installed horizontally in an attic, basement, crawl space, alcove, or suspended from a ceiling in a basement or

1 ,

utility room. See Figure 4. Do not install furnace on its back or in the reverse airflow positions as safety control operation will be ad- versely affected.

NOTE: 6" bottom clearance requiredfor condensatetrap.

If the furnace is to be suspended from the floor joists in a crawl space or the rafters in an attic, it is necessary to use steel pipe straps or an angle iron frame to rigidly attach the furnace to prevent movement. These straps should be attached to the furnace with sheet metal screws and to the rafters or joists with bolts. The pre- ferred method is to use an angle iron frame bolted to the rafters or

joists. (Take caution to allowdoor panels to be removed for mainte-

nance) If the furnace is to be installed in a crawl space, consult local

codes. A suitable concrete pad or blocks are recommended for crawl space installation on the ground.

NOTE: 6" bottom clearance required for condensate trap. Thirty (30) inches between the front of the furnace and adjacent

construction or other appliances MUST be maintained for service clearance.

Keep all insulating materials clear from Iouvered door. Insulating materials may be combustible.

The horizontal furnaces may be installed directly on combustible wood flooring or supports as long as all required furnace clear-

ances are met. See Figure 4. This furnace MUST NOT be installed directly on carpeting or tile or

other combustible material other than wood flooring or supports. For horizontal installation over a finished living space. A field fabri-

cated auxiliary drain pan with drain pipe is required to prevent damage by overflow due to blocked condensate drain.

3. Combustion & Ventilation Air

For Single Pipe Installation

CARBON MONOXIDE POISONING HAZARD.

Failure to provide adequate combustion and ventilation air could result in death and/or personal injury.

Use methods described here to provide combustion and ventilation air.

Furnaces require ventilation openings to provide sufficient air for proper combustion and ventilation of flue gases. All duct or open-

ings for supplying combustion and ventilation air must comply with the gas codes, or in the absence of local codes, the applicable na-

tional codes.

Combustion and ventilation air must be supplied in accordance with one of the following:

1. Section 8.3, Air for Combustion and Ventilation, of the National Fuel Gas Code, (NFGC), ANSI Z223.1-2002/NFPA 54-2002

in the U.S.,

2. Sections 7.2, 7.3, 7.5, 7.6, 7.7, and 7.8 of National Standard of Canada, Natural Gas and Propane Installation Code

(NSCNGPIC), CSA B149.1-00 in Canada,

3. Applicable provisions of the local building code.

This furnace can NOT be common vented or connected to any type B, BW or Lvent or vent connector, nor to any portion of a facto- ry- built or masonry chimney. If this furnace is replacing a previous- ly common-vented furnace, it may be necessary to resize the existing vent and chimney to prevent oversizing problems for the a. other remaining appliance(s). See "Venting and Combustion Air

Check"in this section, This furnace MUST be vented to the out- side. b.

When the installation is complete, check that all appliances have adequate combustion air and are venting properly. See Venting

And Combustion Air Check in "4. Gas Vent Installation"Section in this manual.

Outdoor Combustion Air Method

A space having less than 50 cubic feet per 1,000 BTUH input rating for all gas appliances installed in the space requires outdoor air for

combustion and ventilation.

Air Openings andConnecting Ducts

1. Total input rating for all gas appliances in the space MUST be considered when determining free area of openings.

Connect ducts or openings directly to the outdoors.

When screens are used to cover openings, the openings MUST be no smaller than 1/4" mesh.

The minimum dimension of air ducts MUST NOT be less than

When sizing a grille, louver, or screen use the free area of opening. If free area is NOT stamped or marked on grill or lou-

ver, assume a 20% free area for wood and 60% for metal. Screens shall have a mesh size not smaller than 1/4".

Requirements

1. Provide the space with sufficient air for proper combustion and ventilation of flue gases using horizontal or vertical ducts or openings.

2. Figure 5 illustrates how to provide combustion and ventilation air when two permanent openings, one inlet and one outlet, are

used.

One opening MUST commence within 12" of the floor and the second opening MUST commence within 12" of the ceiling.

CARBON MONOXIDE POISONING HAZARD.

Failure to supply adequate combustion air could result in death and/or personal injury.

Most homes will require additional air from outdoors for combustion and ventilation. A

space with at least 50 cubic feet per 1,000 BTUH input rating or homes with tight construction may need outdoor air, supplied through ducts, to supplement air infiltration for proper

combustion and ventilation of flue gases.

ume than 50 cubic feet per 1,000 BTUH input rating for all gas ap- pliances installed in the space. The standard method permits

indoor air to be used for combustion and ventilation air. The Known Air Infiltration Rate Method shall be used if the in-

filtration rate is known to be less than 0.40 air changes per hour (ACH) and equal to or greater than 0.10 ACH. Infiltration rates greater than 0.60 ACH shall not be used. The minimum required

volume of the space varies with the number of ACH and shall be determined per Table 2 or Equations 1 and 2. Determine the minimum required volume for each appliance in the space, and

add the volumes together to get the total minimum required vol- ume for the space.

The following requirements apply to the Standard Method and to the Known Air Infiltration Rate Method.

• Adjoining rooms can be considered part of a space, if there

are no closable doors between rooms. Combining spaces on the same floor level. Each opening

shall have a free area of at least 1" 2/1,000 BTUH (2,000 mm2/kW) of the total input rating of all gas appliances in the space, but not less than 100 in2 (0.06 m2). Once opening shall commence within 12" (300 ram) of the ceiling and the second opening shall commence within 12" (300 ram) of the

floor. The minimum dimension of air openings shall be at least 3" (80 ram).

Combining spaces on different floor levels. The volumes of spaces on different floor levels shall be considered communi- cating spaces if connected by one or more permanent open- ings in doors or floors having a free area of at least 2" 2/1,000 Btuh (4,400 mm2/kW) of total input rating of all gas ap- pliances.

1. Walls and ceilings exposed to the outdoors have a con- tinuous, sealed vapor barrier. Openings are gasketed or

sealed and

Doors and openable windows are weather stripped and

Other openings are caulked or sealed. These include

joints around window and door frames, between sole

plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines, etc.

Ventilation Air

Some provincial codes and local municipalities require ventilation or make-up air be brought into the conditioned space as replace- ment air. Whichever method is used, the mixed return air tempera-

ture across the heat exchanger MUST not fall below 60 ° so that flue gases will not condense excessively in the heat exchanger. Excessive condensation will shorten the life of the heat exchanger

and possibly void your warranty.

Venting and Combustion Air Check

NOTE: When an existing Category I furnace is removed or re- placed, the original venting system may no longer be sized to prop-

erly vent the attached appliances, and to make sure there is adequate combustion air for all appliances, MAKE THE FOL-

LOWING CHECK.

[_ 44001 1020 05

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each

appliance connected to the venting system being placed into operation, could result in carbon monoxide poisoning or death:

The following steps shall be followed for each appliance connected to the venting system being

placed into operation, while all other appliances connected to the venting system are not in operation:

1. Seal any unused openings in the venting system.

2. Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI

Z223,1/NFPA 54 or CSA B149, 1, Natural Gas and Propane Installation Code and these instructions. Deter-

mine that there is no blockage or restriction, leakage,

corrosion and other deficiencies which could cause an

unsafe condition.

3. As far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building.

4. Close fireplace dampers.

5. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as

range hoods and bathroom exhausts, so they are

operating at maximum speed. Do not operate a summer exhaust fan.

6. Followthe lighting instructions. Place the appliance being

inspected into operation. Adjust the thermostat so

appliance is operating continuously.

7. Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle. (Figure 6)

8. If improper venting is observed, during any of the above tests, the venting system must be corrected in

accordance with the National Fuel Gas Code, ANSI

Z223,1/NFPA 54 and/or CSA B149. 1, Natural Gas and Propane Installation Code.

9. After it has been determined that each appliance connected to the venting system properly vents when

tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas-fired burning appliance to their previous conditions of use.

4. Vent and Combustion Air Piping

CARBON MONOXIDE POISONING HAZARD.

Failure to properly vent this furnace could result in death and/or personal injury.

Use methods described here to provide combustion and ventilation air.

SinglePipe(N9MP1Models)

This furnace is certified as a category IV appliance. This furnace requires ventilation openings to provide air for proper combustion and ventilation of flue gases. All duct or openings for supplying combustion and ventilation air must comply with the gas codes or in absence of local codes, the applicable national codes.

When the installation is complete, see the" VentingandCombus- tion Air Checl(' in this manual.

Direct Vent (N9MP2 Models)

This furnace is certified as a category [V appliance. This furnace uses outside air for combustion ONLY, it MUST be taken from the

same atmospheric pressure zone as the vent pipe. See Confined Space Installation in the Combustion and Ventilation Air in this

manual.

Dual Certified (*9MPD Models)

This furnace is certified as a category [V appliance. This furnace can be installed as a direct vent furnace using outside air for com-

bustion or the furnace can use air from inside the structure for com- bustion. The INLET air pipe is optional. If combustion air comes

from inside the structure, adequate make u p air MUST be provided to compensate for oxygen burned. See Confined Space Installa- tion in the Combustion and Ventilation Air chapter. If combus-

tion air is drawn from outside the structure, it MUST be taken from the same atmospheric pressure zone as the vent pipe.

Contaminated Combustion Air

Installations in certain areas or types of structures could cause ex- cessive exposure to contaminated air having chemicals or halo-

gens that will result in safety and performance related problems and may harm the furnace. These instances must use only out-

door air for combustion. The following areas or types of structures may contain or have ex-

posure to the substances listed below. The installation must be evaluated carefully as it may be necessary to provide outdoor air

for 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.

• Chlorine based swimming pool chemicals.

• Water softening chemicals.

• De-icing salts or chemicals.

• Carbon tetrachloride.

• Halogen type refrigerants.

• Cleaning solvents (such as perchloroethylene).

• Printing inks, paint removers, varnishes, etc.

• Hydrochloric acid.

• Sulfuric Acid.

• Solvent cements and glues.

• Antistatic fabric softeners for clothes dryers.

• Masonry acid washing materials.

Vent and Combustion Air Piping Guidelines

This furnace is approved for venting with Schedule 40 PVC, CPVC, ABS, Cellular Core pipe fittings and SDR-26 PVC.

NOTE: All PVC, CPVC, ABS, and Cellular Core pipe fittings, sol- vent cement, primers and procedures MUST conform to American National Standard Institute and American Society for Testing and

Materials (ANSI/ASTM) standards.

• PipeandFittings-ASTMD1785, D2241,D2466, D2661, D2665, F-891, F-628

• PVC Primer and Solvent Cement - ASTM D2564

• Procedure for Cementing Joints - Ref ASTM D2855

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

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

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

3. Loosely assemble all venting parts without adhesive (pipe

joint cement) for correct fit before final assembly.

4. Use of vertical piping is preferred because there will be some moisture in the flue gases that may condense as it leaves the vent pipe (See Speciallnstruction ForHorizontal

Vents).

5. The vertical vent pipe MUST be supported so that no weight is allowed to rest on the combustion blower.

6. Exhaust vent piping or air inlet piping diameter MUST NOT be reduced.

7. All exhaust vent piping from the furnace to termination MUST slope upwards. A minimum of 1/4" per foot of run is

required to properly return condensate to the furnace drain system.

8. Use DWV type long radius elbows whenever possible, as they provide for the minimum slope on horizontal runs and they provide less resistance in the vent system. If DWV el- bows cannot be used, use two, 45 ° elbows when possible. On horizontal runs the elbows can be slightly misaligned to provide the correct slope.

9. All horizontal pipe runs MUST be supported at least every five feet with galvanized strap or other rust resistant materi- al. NO sags or dips are permitted.

10. All vertical pipe runs MUST be supported every six feet where accessible.

11. The minimum pipe run length is 2'.

12. The piping can be run in the same chase or adjacent to sup- ply or vent pipe for water supply or waste plumbing. It can

also be run in the same chase with a vent from another 90+ furnace.

NOTE: In NO case can the piping be run in a chase where temperatures can exceed 140 ° F. or where radiated heat from adjacent surfaces would exceed 140 ° F.

13. The vent outlet MUST be installed to terminate in the same atmospheric pressure zone as the combustion air inlet.

14. The vent system can be installed in an existing unused chimney provided that:

• Both the exhaust vent and air intake run the length of the chimney.

[_ 44001102005

• No other gas fired appliance or fireplace (solid fuel) is vented into the chimney

• The top of the chimney MUST be sealed flush or crowned up to seal against rain or melting snow so ONLY the piping protrudes.

• The termination clearances shown in Figure 7 & Figure 8 are maintained.

15. Furnace applications with vertical vents requiring vent di- ameter increaser fittings must have increaser fittings installed in vertical portion of the vent. Condensate will be trapped in the vent if the vent diameter is increased prior to

having an elbow turned upward. This could cause nuisance

tripping of the pressure switch.

Piping Insulation Guidelines

NOTE: Use closed cell, neoprene insulation or equivalent. If Fiber- glass or equivalent insulation is used it must have a vapor barrier. Use Rvalues of 7 upto 10', R-11 if exposure exceeds 10'. If Fiber- glass insulation is used, exterior to the structure, the pipe MUST be boxed in and sealed against moisture.

1. When the vent or combustion air pipe height above the roof exceeds 30", or if an exterior vertical riser is used on a hori-

zontal vent to get above snow levels, the exterior portion MUST be insulated.

2. When combustion air inlet piping is installed above a sus- pended ceiling, the pipe MUST be insulated with moisture resistant insulation such as Armaflex or other equivalent type of insulation.

3. Insulate combustion air inlet piping when run in warm, hu- mid spaces such as basements.

Sizing Combustion Air and Vent Pipe

Consult Table 3 or Table 4 to select the proper diameter exhaust and combustion air piping. Exhaust and combustion air piping is sized for each furnace Btuh size based on total lineal vent length (on inlet oroutlet side), and number of 90 ° elbows required. Two

45 ° elbows can be substituted for one 90 ° elbow. The elbow or el- bows used for venttermination outside the structure ARE counted,

including elbows needed to bring termination above expected snow levels. The elbow inside the furnace on the *9MPD IS NOT

included in the count.

CondensateDrainTrap

This furnace removes both sensible and latent heat from the prod- ucts of combustion. Removal of the latent heat results in con-

densation of the water vapor. The condensate is removed from the furnace through the drains in the plastic transition and the vent fit-

ting. The drains connect to the externally mounted condensate drain trap on the left or right side of the furnace.

The startup of a new furnace will involve a cycle or two of the fur- nace to properly prime the condensate trap with water. Until the

trap is fully primed, some condensate will be pulled into the com- bustion blower. The furnace may cycle on the pressure switch con-

nected to the plastic transition box due to condensate buildup. After the trap is primed, the condensate will start draining from the

furnace. The combustion blower will clear out any remaining con- densate in the blower housing through the vent fitting downstream

of the blower. Note that the condensate trap can also be primed by pouring water into the 1/2" drain hose. Remove the1/2 " ID drain hose from either the gutter or the white PVC Tee Trap. Using a fun- nel pour eight (8) ounces of water into 112" ID drain hose.Water will

flow through the drain hose and into the condensate drain trap. This will prime both the vent and the transition sides of the trap. Re-

connect the 1/2, ID drain hose to the original component, either the gutter or the PVC Tee Trap.

The condensate drain trap supplied with the furnace MUST be used. The drain connection on the condensate drain trap is sized for 3/4" PVC or CPVC pipe, however alternate 1/2" CPVC (nominal

5/8" O.D.) or vinyl tubing with a minimum inner diameter (I.D.) of 5/8" may also be used, as allowed by local codes. Alternate drain

pipes and hoses may be used as allowed by local codes.

The drain line must maintain a I/4" per foot downward slope toward the drain. 114"per foot is recommended. Installation of an overflow line is recommended when the 114" per foot slope to the conden-

sate drain cannot be maintained. See Figure 18 for proper routing and installation of the overflow.

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

FROZEN AND BURST WATER PIPE HAZARD Failure to do so could result in burst water pipes,

serious property damage and/or personal injury. If a condensate pump is installed, a plugged

condensate drain or a failed pump may cause the furnace to shut down. Do not leave the home

unattended during freezing weather without turning off water supply and draining water pipes or otherwise protecting against the risk of frozen pipes.

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

1. A condensate sump pump MUST be used if required by lo- cal codes, or if no indoor floor drain is available. The con-

densate pump must be approved for use with acidic condensate.

2. A plugged condensate drain line or a failed condensate pump will allow condensate to spill. If the furnace is installed where a condensate spill could cause damage, it is recom-

mended that an auxiliary safety switch be installed to pre- vent operation of the equipment in the event of pump failure or plugged drain line. If used, an auxiliary safety switch should be installed in the R circuit (low voltage) ONLY.

3. If the auxiliary switch in the condensate pump is used, the furnace may shut down dueto a blocked condensate line or failed pump. To prevent frozen water pipes see the "Frozen

Water Pipe Hazard" section on Page 4 of this manual.

Condensate Drain Trap Freeze Protection

Special precautions MUST be made if installing furnace in an area which may drop below freezing. This can cause improper opera- tion or damage to the equipment. If the the furnace environment has the potential of freezing, the drain trap and drain line must be protected. Use 3 to 6 watt per foot at 11 5 volt, 40 ° Fself-regulating shielded and waterproof heat tape. Wrap the drain trap and drain line with the heat tape and secure with the ties. Follow the heat tape manufacturer's recommendations.

(Opt L

Main Drain Line

The Tee Trap must be connected to the main condensate drain line as conceptually shown above. Different installations may require slightly different orientations. The following steps apply

to all installations.

2. The Tee Trap should be installed as close to the side or top of the furnace as practical. Minimize the distance between the inducer and the Tee Trap as much as possible.

3. An open tee is to be used at the Tee Trap discharge. The top end of the tee should be open to the atmosphere to elimi- nate potential air lock problems.

4. The drain line from the Tee Trap is to be connected to the furnace condensate trap drain line as shown above.

5. Condensate drain lines from a cooling coil may be con- nected downstream of the connection point of the Tee Trap

and Furnace Condensate Trap.

Important: Prime both traps with water before operation. Failure to prime the traps may result in discharge of flue gases from the condensate drain line and open tee for a period of

time, and may result in temporary lockout of the furnace upon start up. Main drain line construction is left to the discretion of the installer. It may be made of either ridged pipe or flexible

tube. Tube ID should NOT be less than 1/2,.

25-24-41N

Condensate Trap

Refer to Figure 9 through Figure 17 that corresponds to the installation position of the furnace for the application.

Preassemble the vent and combustion air piping from the furnace to the vent termination. Do not cement the pipe joints until the pipe preassembly process is complete.

Combustion Air Pipe Connection (Dual Certified or

Direct Vent)

Install the air intake coupling and gasket to the furnace with the four(4) screws.

Note: The air intake cou piing and gasket ca n be installed to the top panel to the alternate air intake locations on either the left or right side panels of the furnace.

For downflow installation, the air intake coupling and gasket must

be installed to the alternate air intake location on either the left or right side panels. Remove the 3" hole plug from the side panel and

relocate to the air intake hole in the top panel. Use four screws to seal the four(4) mounting holes in the top panel next to the hole plug. Drill four(4) 7/64" diameter holes in the casing using the air intake coupling as the template.

The air intake coupling is sized for 2" PVC pipe.

Install the combustion air pipe to the air intake coupling using RTV sealant to provide for future serviceability.

Vent Pipe Connection

Install the vent pipe grommet to the furnace panel. Locate the grommet in the furnace panel at a location directly away from the vent fitting on the combustion blower. The grommet snaps into the 3" hole plug from the furnace panel. NOTE: Depending on the installation position, the vent pipe grommet will be installed to the top panel or to the alternate location on the side panels. If needed, remove the 3" hole plug from the furnace panel and relocate to the open hole in the furnace panel. (See Figure 9 or Figure 18)

Install the vent pipe to the rubber coupling, the vent fitting or the PVC vent extension pipe. Securely attach using the clamp or PVC cement as required.

Note: The vent fitting MUST be installed with the air flow marking arrow pointed toward the vent pipe. (See Figure 19) Some installations require the vent fitting to be installed with a 5 ° to 10 ° downward slope. (See Figure 9 thru Figure 18)

Joining Pipe and Fittings

FIRE HAZARD Failure to do so could cause personal injury and/or

property damage. Observe all cautions and warnings printed on

material containers

Provide adequate ventilation and do NOT assemble near heat source or open flame. Do NOT smoke

while using solvent cements and avoid contact with

skin or e_es.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal property damage, injury or death.

Do NOT use solvent cement that has become

curdled, lumpy or thickened and do NOT thin.

Observe precautions printed on containers. For applications below 32° F., use only low temperature

type solvent cement. Poor joints may lead to

disconnected or leaking vent pipe joints allowing

carbon monoxide to enter the living space.

1. Cut pipe end square, remove ragged edges and burrs. Chamfer end of pipe, then clean fitting, socket and pipe joint of all dirt, grease, or moisture.

NOTE: Stir the solvent cement frequently while using. Use a natu- ral bristle brush or the dauber supplied with the cement. The prop-

er brush size is one inch.

2. After checking pipe and socket for proper fit, wipe socket and pipe with cleaner-primer. Apply a liberal coat of primer to inside surface of socket and outside of pipe. Do NOT al- low primer to dry before applying cement.

3. Apply a thin coat of cement evenly in the socket. Quickly ap- ply a heavy coat of cement to the pipe end and insert pipe

into fittings with a slight twisting movement until it bottoms out.

NOTE: Cement MUST be fluid while inserting pipe. If NOT, recoat pipe.

4. Hold the pipe in the fitting for 30 seconds to prevent the ta- pered socket from pushing the pipe out of the fitting.

5. Wipe all excess cement from the joint with a rag. Allow 15 minutes before handling. Cure time varies according to fit, temperature and humidity.

Connecting Vent Pipes and lermination

NOTE: Combustion air intake and vent MUST terminate in the same atmospheric pressure zone. If installation isin a cold climate

(sustained temperatures below 0°F), increase the minimum dis- tance between vent pipe and air intake from 8" to 18".

This furnace is approved for venting with Schedule 40 PVC, CPVC, ABS, Cellular Core pipe fittings and SDR-26 PVC.

NOTE: All PVC, CPVC, ABS, and Cellular Core pipe fittings, sol- vent cement, primers and procedures MUST conform to American National Standard Institute and American Society for Testing and Materials (ANSI/ASTM) standards.

Cut two holes. 21/2" for 2" pipe, 3" for 21/2 " pipe, or 31/2" for 3" pipe. Do NOT make the holes oversized, or it will be nec- essary to add a sheet metal or plywood plate on the outside

with the correct size hole in it.

2. Check hole sizes by making sure it is smaller than the cou- plings or elbows that will be installed on the outside. The couplings or elbows MUST prevent the pipe from being pushed back through the wall.

3. Extend vent pipe and combustion air pipe through the wall 3/4" to 1" and seal area between pipe and wall.

4. Install the couplings, nipple and termination elbows as shown and maintain spacing between vent and combustion

air piping as indicated in Figure 20 and Figure 21.

A metal shield is recommended 18" x 18" min. or 18" min. diameter around the vent termination at the exterior wall to protect the house

exterior materials from flue product or condensation (freezing) damage.

Using ExteriorRisers

1. Install elbows and pipe to form riser as shown in Figure 21.

2. Secure vent pipe to wall with galvanized strap or other rust resistant material to restrain pipe from moving.

3. Insulate pipe with Armaflex or equivalent moisture resistant closed cell foam insulation or Fiberglass insulation if boxed in and sealed against moisture.

should be sealed with a plumbing roof boot or equivalent flashing. The inlet of the intake pipe and end of the exhaust

vent must be terminated no less than 12" above the roof or snow accumulation level, and 12" away from a vertical wall

or other protrusion.

2. If the vent system is installed in an existing chimney make sure clearances shown in Figure 22 are maintained. Hori-

zontal section before the termination elbow can be ex- tended on the inlet air to provide necessary clearance.

Vent Termination Shielding

Under certain wind conditions some building materials may be af- fected by flue products expelled in close proximity to unprotected surfaces. Sealing or shielding of the exposed surfaces with a cor- rosion resistant material (such as aluminum sheeting) may be re- quired to prevent staining or deterioration. The protective material should be attached and sealed (if necessary) to the building before attaching the vent terminal.

Multi Vent Termination Clearances

When two (2) or more furnaces are vented near each other, each furnace must be individually vented.

Two (2) vent terminations may be installed as shown in Figure 23, Figure 24, Figure 25, Figure 26, Figure 27 and Figure 28, but

the next vent termination must be at least 36" away from first 2 ter- minations. It is important that vent terminations be made as shown to avoid recirculation of flue gases.

could result in death, bodily injury and/or property

damage.

A flexible corrugated metal gas connector must be properly installed, shall not extend through the side

of the furnace,and shall not be used inside the furnace.

Black iron pipe shall be installed at the furnace gas control valve and extend a minimum of 2" outside

furnace casing.

4. Use black iron or steel pipe and fittings or other pipe ap- proved by local code.

ways use a new listed connector. Do not use a connector which NOTE: If local codes allow the use of a flexible gas connector, al- has previously serviced another gas appliance.

NOTE: The use of copper tubing for gas piping is NOT approved by the state of Massachusetts.

5. Use ground joint unions and install a drip leg no less than 3" long to trap dirt and moisture before it can enter gas valve.

6. Use two pipe wrenches when making connections to pre- vent gas valve from turning.

7. Install a manual shut-off valve external to furnace casing and tighten all joints securely.

FIRE OR EXPLOSION HAZARD A natural gas or LP gas leak ignited by an open flame

or spark could result in death, personal injury and/or property damage.

Natural gas is lighter than air and will rise. Liquified petroleum (LP) is heavier than air and will settle and

remain in low areas and open depressions. Thoroughly ventilate area and dissipate gas. Do

NOT use a match or open flame to test for leaks, or attempt to start up furnace before thoroughly ventilating area.

FinalCheck

1. The furnace and the gas valve must be disconnected from the gas supply piping system during any pressure testing of that

system at test pressures in excess of 1/2" PSIG. Close the manual shut-off valve before testing at such pressures.

2. When installation is complete, test all pipe connections for leaks with the gas pressure less than /2' PSIG to the gas

valve.

Apply a commercial soap solution to all joints to test for leaks. Correct any leaks indicated by bubbles.

Correct even the smallest leak at once.

Check for leaks at gas valve and orifice connections to the burner manifold along with the pilot tube connections to the

valve and pilot assembly while the furnace is operating.

NOTE: Design and install air distribution system to comply with Air Conditioning Contractors of Arnerica manuals andlor NFPA pam- phlets 90A and 90B or other approved methods that conform to lo- cal codes and good trade practices.

I. When furnace supply ducts carry air outside furnace area,

seal return air duct to furnace casing and terminate duct out- side furnace space.

2. Install air conditioning cooling coil (evaporator) on outlet side of furnace.

3. For furnaces installed without a cooling coil it is recom- mended that the outlet duct be provided with a removable

access panel. This panel should be accessible when the furnace is installed so the exterior of the heat exchanger can be viewed for inspections. The access panel MUST be sealed to prevent leaks.

4. If separate evaporator and blower units are used, install good sealing dampers for air flow control. Chilled air going through the furnace could cause condensation and shorten

the furnace life.

NOTE: Dampers (field supplied) can be either automatic or manu- al. Manually operated dampers MUST be equipped with a means to prevent furnace or air conditioning operation unless da roper is in the full heat or cool position.

CARBON MONOXIDE POISONING HAZARD.

Failure to follow this warning could result in death, personal injury and/or property damage.

Cool air passing over heat exchanger can cause condensate to form resulting in heat exchanger

failure.

Connections

NOTE: On upflow installations, return air can enter through either side, both sides, or the bottom. On horizontal or downflow installa-

tions the return air must enter through the knockout opening in the lower panel of the furnace. Return air can not enter through rear of the furnace. When the furnace is located in an area near or adja- cent to the living area, the system should be carefully designed with returns to minimize noise transmission through the return grille. Any blower moving a high volume of air will produce audible noise which could be obJectionable to when the unit is located very close to living areas. It is advisable to route the return air ducts un-

der the floor or through the attic.

I. For side connections using a 16" x 25" filter, cut out the em-

bossed area shown in Figure 34. This will provide a 14112,, x 22112 ,, approximate opening.

Embossed Area on Side of Furnace j_-

_'_ Furnace

" Bottom

NOTE: Furnaces with 5 TONS cooling rating require two(2) side returns or one side return with bottom return.

2. Bottom returns can be made by removing the knockout pan- el in the furnace base. Do NOT remove knock-out except for

a bottom return.

3. Installation of locking-type dampers are recommended in all branches, or in individual ducts to balance system's air flow.

4. Non-combustible, flexible duct connectors are recom- mended for return and supply connections to furnace.

5. If air return grille is located close to the fan inlet, install at least one, 90 ° air turn between fan and inlet grille to reduce

noise.

NOTE: To further reduce noise, install acoustical air turning vanes and/or line the inside of duct with acoustical material.

Sizing

Existing or new ductwork MUST be sized to handle the correct amount of airflow for either heating only or heating and air condi-

tioning.

Insulation

1. Insulate ductwork installed in attics or other areas exposed to outside temperatures with a minimum of 2" insulation and

vapor barrier.

2. Insulate ductwork in indoor unconditioned areas with a mini-

mum of 1" insulation with indoor type vapor barrier.

Filters

A Filter must be used:

Filters are not supplied with these furnaces, but can be purchased from dealer.

Use either filter type:

• Washable, high velocity filters are based on a maximum

air flow rating of 600 FPM.

• Disposable, Iowvelocity filters are based on a maximum

air flow of 300 FPM when used with filter grille.

NOTE: Disposable, low velocity filters may be replaced with wash- able, high velocity filter providing they meet the minimum size areas. Washable, high velocity filters can be replaced ONLY with same type and size.

Filter Installation using Optional Filter Rack

When installing or removing a bottom mounted filter, slide the two side filter clips to the back of the furnace BEFORE installing or re- moving. This will allow the filter to clear the front raised edge of the furnace. Insert filter into side clips first and push filter back until it is fully engaged into back clip. When filter is in place, slide clips back into place midway on filter as shown in Figure 36.

Bottom Mounted Filter Rack

CAUTION

If filters are only suitable for heating application, advise homeowner that filter size may need to be increased if air conditioning is added.

Addition Of Air Conditioning

When a refrigeration coil is used in conjunction with this unit, it must be installed on the discharge side of the unit to avoid con- densation on the heat exchanger. The coil installation instructions must be consulted for proper coil location and installation proce- dures. With a parallel flow arrangement, dampers must be installed to prevent chilled air from entering the furnace. If ma nual- ly operated dampers are used, they must be equipped with a means to prevent operation of either unit unless the damper is in full heat or full cool position.

A 3" clearance is required on the right side ofthe furnace in order to run the condensate drain line. Copper, iron or plastic tubing may be

used for the condensate drain line.

Downflow Furnace Installation Non- Combustible Floor Installation

Fabricate a plenum to the dimensions given in Table 11, for the fur- nace outlet. Plenum should be flanged, approximately 3/4" for sup- port.

Note: The three(3) screws in the top panel of the furnace next to the duct flange MUST be removed to provide serviceability of the primary heat exchangers in the downflow installation

1. Position plenum through the floor and set the furnace over the opening in the floor. If necessary, grout around the base

to seal air leaks between the base and the floor.

FIRE HAZARD

Failure to install unit on noncombustible subbase

could result in death, personal injury and/or

property damage.

Place furnace on noncombustible subbase on downflow applications, unless installing on non-

combustible floorinq.

;ubbase for Combustible Floor

NOTE: The three(3) screws in the top panel of the furnace next to the duct flange MUST be removed to provide serviceability of the primary heat exchangers in the downflow installation

Note: When using the subbase for combustible floors, the dis- charge air duct flanges on the furnace MUST be broken down to provide proper fit up to the subbase. Use duct pliers to bend the duct flanges flat onto the furnace casing. DO NOT bend the duct flanges inward (toward the heat exchangers) as air flow restric- tions may occur.

The Subbase for Combustible Floors MUST be used when a downflow furnace is set on a combustible floor, even when the fur-

nace is installed on a coil box.

1. Cut the opening in the floor according to Table 11. The hole in the floor must be cut to the dimensions listed in Table 11

since the base is equipped with locating tabs that center the base over the opening.

The opening in the base is 11/4 ', shorter and 11/8', narrower than the recommended size of the opening in the floor. This is done to maintain clearance between the floor and the plenum.

2. Fabricate the plenum to the dimensions given in Table 11. Note that the dimensions given are outside dimensions.

Adjust Pilot Burner

FIRE OR EXPLOSION HAZARD. Failure to turn OFF gas at shut off before

connecting manometer could result in death, personal injury and/or property damage.

Turn OFF gas at shut off before connecting manometer.

Startup

NOTE: Refer to the start-up procedures in the "User's Information Manual' or to the "Operating Instructions Label' on the furnace.

FIRE OR EXPLOSION HAZARD. Failure to correct hazard could result in death,

personal injury, and/or property damage. If any sparks, odors or unusual noises occur,

immediately shut OFF power to furnace. Check for

wiring errors or obstruction to blower.

GasSupplyPressure

Gas supply pressure should be within minimum and maximum val- ues listed on rating plate. Pressures are usually set by gas suppli-

ers.

The furnace has a pilot flame to light the main burner. The flame should surround /8' to /2' of the flame sensor. See Figure 42. To

adjust, remove cap from pilot adjusting screw on gas valve. Turn screw counterclockwise to increase or clockwise to decrease

flame as required. Replace adjusting screw cap.

Turn gas ON and remove adjustment screw cover on gas valve. Turn counterclockwise to decrease pressure and

clockwise to increase.

For altitudes up to 2000', set pressure to value shown in Table 6 or Table 8, _+0.3" (8ram) water column. For alti-

tudes of 2000' to 8000', see Section 5 for correct pressure setting.

44001 102005 E_

Allow the furnaceto run approximately 10 minutes then inspect the main burner and pilot flames. See Figure 43.

Check for the following (Figure 43):

• Stable and blue flames. Dust may cause orange tips or wisps ofyellow, but flames MUST NOT have solid, yellow

tips.

• Flames extending directly from burner into heat ex- changer.

• Flames do NOT touch sides of heat exchanger.

If any problems with main burner flames are noted, it may be nec- essary to adjust gas pressures, or check for drafts.

Main Burner

Face

Ifitisnecessarytochange speeds, refer to steps below.

Refer to Furnace WMng Diagramfor location of the heating and cooling speed taps located on the electronic fan control as well as location of unused blower motor speed leads.

Use the chart (Table 12) to determine the blower motor speed settings.

Blower Speed Chart

10-10-78

Temperature Rise Check

The blower speed MUST be set to give the correct air temperature rise through the furnace as marked on the rating plate. Tempera- ture rise is the difference between supply and return air tempera-

tures.

To check temperature rise,use the following procedure:

1. Place thermometers in supply and return air registers as close to furnace as possible, avoiding direct radiant heat from heat exchangers.

2. Operate furnace continuously for 15 minutes with all regis- ters and duct dampers open.

3. Take reading and compare with range specified on rating plate.

4. If the correct amount of temperature rise is NOT obtained, it may be necessary to change blower speed. A higher blower

speed will lower the temperature rise. A lower blower speed will increase the temperature rise.

* Med-High speed may not be provided on all models.

Change the heat or cool blower motor speed by removing the motor lead from the "Heat" or "coor' terminal and re-

place it with the desired motor speed lead from the "Un- used Motor Lead" location. Connect the wire previously

removed from the "Heat" or "coor' terminal to the vacated "Unused Motor Lead" terminal.

If the same speed must be used for both heating and cool- ing, remove the undesired motor speed lead from the "Heat" or "Cool" terminal and connect that lead to the open terminal at "Unused Motor Lead" location. Attach a jumper between the "Heat" and "Cool" terminals and the remaining motor speed lead.

Note: For motors with (4) speed leads, it will be necessa ryto tape off the terminal of the motor speed lead removed from the "Heat" or "Cool" terminal with electrical tape since an open terminal will not be available at the "Unused Motor

Lead" location.

ELECTRICAL SHOCK HAZARD Failure to do so could result in death and/or

personal injury. Turn OFF power to furnace before changing

speed taps.

NOTE: The speed taps that the manufacturer sets from the factory for this product are based on a nominal 400 CFM per ton cooling and the basic mid range on the temperature rise for heating.

Since the manufacturer cannot establish the static pressure that will be applied to the unit, it is the responsibility of the in-

staller dealer/contractor to select the proper speed taps for the application when the unit is installed.

REDUCED FURNACE LIFE HAZARD

Failure to properly set the air temperature rise may result in reduced furnace life.

Use ONLY the following blower motor speed taps for setting air temperature rise.

Blower Motor Speed Taps Model Sizes Hi (BLK) All

Med-Hi (O) All except 050F/J14 Med Lo (BL All except 075B/F12

and 100F/J14

and 125J/L20

Continuous Fan Operation

A terminal is provided on the electronic fan control located in the circulating blower compartment for operation of the continuous fan option. This connection is intended for the low speed motor tap, and has a lower contact rating (8 amps) than the heat and cool taps. When the low speed blower lead is connected to this termi- nal, this will provide low speed blower operation whenever the oth- er two speeds (Heat or Cool) are not energized.

Thoroughly check the system after modification to ensure the proper operation of the circulating air blower in all modes of opera-

tion.

Separate speed selections for Heat, Cool, and Continuous Fan

Connect low speed lead from circulating motor to the "Cont." ter- minal at the electronic fan control. The appropriate motor leads should already be connected to the "Heat" and "coor' terminals.

HeatingandContinuous BlowerSpeed the Same

If it is necessary to operate the heating speed and continuous blower speed using the same blower speed, connect ajumper be-

tween the "Heat" and "Cont." terminals on the electronic fan con- trol.

Note: There should be only ONE motor lead going to the "Heat" and "Cont." terminals.

9. Furnace Maintenance

FIRE, EXPLOSION, OR CARBON MONOXIDE HAZARDS

Failure to have the furnace inspected and maintained could result in fire, explosion, or carbon monoxide poisoning.

It is recommended that the furnace be inspected and serviced on an annual basis (before the heating

season) by a qualified service technician.

ELECTRICAL SHOCK, FIRE OR EXPLOSION HAZARD

Failure to follow safety warnings exactly could result in dangerous operation, serious injury, death or property damage.

Improper servicing could result in dangerous operation, serious injury, death or property damage.

• Before servicing, disconnect all electrical power to furnace.

• When servicing controls, label all wires prior to disconnecting. Reconnect wires correctly.

• Verify proper operation after servicing.

See "User's Information Manual" and the "Service Manual".

Vertical & Horizontal Termination

1. Determine the pipe diameters required for the installation from Table 13 and Table 14 and Figure 47.

2. Determine the best location for the termination kit. See Figure46 for vertical termination or Figure46 and

Figure 50 for horizontal termination. Roof termination is preferred since it is less susceptible to damage, has re- duced intake contaminants and less visible vent vapor• For side wall termination, consideration should be given to: 1) possible damage from the vapors to plants/shrubs, other equipment and building materials, 2) possible damage to the terminal from foreign objects, 3) wind effects that may cause recirculation of flue products, debris or light snowand

4) visible vent vapor•

3. Cut one 5" diameter hole through the structure for the NAHA001CV Kit or one 4" diameter hole for the

NAHA002CV Kit.

4. Dimension D may be lengthened to 60" max. or shortened by cutting the pipes to 12" rain. Dimension A will change ac- cording to D dimension• (See Figure 47)

1. Do not include the field supplied 45 ° elbow in the total elbow count,

2, If more than four elbows are required, reduce the length of both the inlet and the exhaust pipes five feet for each

additional elbow used.

3. Elbows are DWV long radius type for 2" and 3" vents.

NOTE: Feet of pipe is whichever pipe run is the longest, either inlet or outlet side.

If assembly needs to be extended to meet height or side wall thick- ness requirement, the two pipes supplied in the kit may be re-

placed by using the same diameter solid, single (no coupling connections) field supplied SDR-26 PVC (ASTM D2241) pipes.

Do not extend dimension D more than 60". (See Figure 47) Do not use field supplied couplings to extend the pipes.

Airflow restriction will occur and the furnace pressure switch may cause intermittent operation.

Partially assemble the concentric vent termination kit. Clean and cement the parts using the procedures for Join- ing Pipe and Fittings section of the manual. A) Cement the Y Concentric fitting to the 4" diameter kit pipe. (See

Figure 48) B) Cement the 3" rain cap to the 21/2" diameter kit part. (See Figure 48) NOTE: A field supplied stainless

steel screw may be used to secure the rain cap to the pipe instead of cementing when field disassembly is desired for cleaning (See Figure 48)

Rain Cap to Vent Pipe Assembly

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in death, personal injury and/or property damage.

When using the alternate screw assembly method,

drill a clearance hole in the rain cap and a pilot hole in the vent pipe for the screw size being used.

Failure to drill adequate holes may cause cracking of the PVC components, allowing flue gases to be

recirculated.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in death, personal injury and/or property damage.

Do not operate the furnace with the rain cap removed as recirulation of the flue gases may

occur. Water may also collect inside the larger combustion air pipe and flow to the burner enclosure.

6. Install the Y concentric fitting and the pipe assemblythrough the structure's hole. For vertical termination, install the parts through the field supplied roof boot/flashing. NOTE: Do not

allow insulation or other materials to accumulate inside the pipe assembly when installing through the structure's hole.

7. Securethe assemblyto the structure as shown in Figure 46 or Figure 50 using field supplied metal strapping or equiva-

lent material. NOTE: Ensure the termination height is above the roof sur-

face or anticipated snow level as shown in Figure 46 for vertical termination. Ensure the termination location clear-

ance dimensions are as shown in Figure 49 and Figure 50 for horizontal termination.
