SafetyRules

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.

A. 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.

Carbon monoxide can cause 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 carbon

monoxide levels, you should have a commercially available

carbon monoxide alarm that is listed by a nationally

recognized testing agency in accordance with Underwriters

Laboratories Inc. Standard for Single and Multiple Station

Carbon Monoxide Alarms, ANSI/UL 2034 or the CSA 6.19-01

Residential 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 instructions.

B. There can be numerous sources of fire or smoke in a building

or dwelling. Fire or smoke can cause 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

Laboratories 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.

C. To ensure safe and efficient operation of your unit, you should

do the following:

1. Thoroughly read this manual and labels on the unit, This

will help you understand how your unit operates and the

hazards involved with gas and electricity.

2. Do not use this unit if any part has been under water,

Immediately call a qualified service technician to inspect the

unit and to replace any part of the control system and any gas

control 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.

FrozenWaterPipeHazard

WATER DAMAGE TO PROPERTY HAZARD

Failure to follow this caution may result in property

damage.

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

devices that are designed to turn the furnace off and prevent it from

restarting in the event of various potentially unsafe conditions.

2. Installation

CARBON MONOXIDE POISONING HAZARD

Failure to properly vent this furnace or other

appliances could result in personal injury or death.

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

previously common-vented furnace, it may be

necessary to resize the existing vent and chimney

to prevent oversizing problems for the other

remaining appliance(s). See Venting and

Combustion Air Check in the Combustion &

Ventilation Air section. This furnace MUST be

vented to the outside.

2. If furnace is a replacement, it is usually best to install the

furnace where the old one was. Choose the location or

evaluate the existing location based upon the minimum

clearance and furnace dimensions (Figure 4).

CARBON MONOXIDE POISONING HAZARD.

Failure to follow this warning could result in

personal injury or death.

Do NOT operate furnace in a corrosive atmosphere

containing chlorine, fluorine or any other damaging

chemicals, which could shorten furnace life.

InstallationRequirements

1. Install furnace level.

2. This furnace is NOT to be used for temporary heat of

buildings or structures under construction.

3. Install furnace as centralized as practical with respect to the

heat distribution system.

4. Install the vent pipes as short as practical, and in

accordance to these instructions. (See Vent and

Combustion Air Piping section).

5. Maintain clearance for fire safety and servicing. A front

clearance of 24" (609.6mm) required and 30" (762mm)

recommended for access to the burner, controls and filter.

See clearance requirements in Figure 4.

6. Use a raised base for upflow furnace if the floor is damp or

wet at times.

7. For downflow installations, non combustible subbase must

be used under the furnace unless installation is on a non

combustible floor surface. This requirement applies even

when a coil box or cabinet is used.

8. For horizontal installations, line contact is permissible only

between lines formed by intersection of back and two sides

of furnace jacket, and building joists, studs or framing.

9. Residential garage installations require:

• Burners and ignition sources installed at least 18"

(457.2mm) above the floor.

• Located or physically protected from possible damage by

a vehicle.

10. Local codes may require a drain pan under the entire

furnace and condensate trap when the furnace is installed in

attic application.

This furnace may be used for construction heat provided that all the

following conditions are met:

• The furnace is permanently installed with all electrical

wiring, 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

minimize 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.

• The temperature of the return air to the furnace is

maintained between 55° F (13° C) and 80° F (27° C), with no

evening setback or shutdown. The use of the furnace while

the structure 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.

• After construction is complete, verify furnace operating

conditions including ignition, input rate, temperature rise

and venting according to these instructions.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal injury or death.

Do NOT operate furnace in a corrosive atmosphere

containing chlorine, fluorine or any other damaging

chemicals, which could shorten furnace life.

Refer to Combustion & Ventilation Air section,

Contaminated Combustion Air for combustion air

evaluation and remedy.

FurnaceInstallationConsiderations

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

following:

Specifications are subject to change without notice.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal injury or death.

Most homes will require additional air from

outdoors for combustion and ventilation. A space

with at least 50 cubic feet per 1,000 BTUH (4.8 cubic

meters per kW) 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.

Standard and Known-Air-Infiltration Rate Methods

Indoor air is permitted for combustion and ventilation, if the

Standard or Known-Air-Infiltration Rate Method is used.

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 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

volume for the space.

CARBON MONOXIDE POISONING HAZARD

Failure to supply additional air by means of

ventilation grilles or ducts could result in personal

injury or death.

The Standard Method may be used, if the space has no less

volume than 50 cubic feet per 1,000 BTUH (4.8 cubic meters per

Table 2 Minimum Space Volumes were determined by using the

following equations from the National Fuel Gas Code ANSI

Z223.1/NFPA 54-2006, 9.3.2.2:

1. For appliances other than fan-assisted appliances (such

as a draft hood-equipped water heater), calculate using the

following equation:

Required Volume other _21ft3 ( |°ther )

-- ACH 1000 BTUH

Required Volume other _59 m3 t! other )

-- ACH .293 kW

2. For fan-assisted appliances (such as this furnace),

calculate using the following equation:

Required Volume fan_ 15ft3 (!fen )

ACH 1000 BTUH

Required Volume fan _ .42 m3 ( ! fan /

ACH .293 kW

where:

!other=all appliances other than fan-assisted input in BTUH

!fan =fan-assisted appliance input in BTUH

ACH = air change per hour (percent of volume of space

exchanged per hour, expressed as a decimal)

3. For purposes of this calculation, an infiltration rate greater

than 0.60 ACH shall not be used in the equations above.

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 ctosable doors between rooms.

Combining spaces on the same story. Each opening shall

have a minimum free area of at least 1 in.2/1,000 BTUH (22

cm2/kW) of the total input rating of all appliances in the space

but not less than 100 in.2 (645 cm2). One opening shall

commence within 12 in. (304.8 mm) of the top, and one

opening shall commence within 12 in. (304.8 mm)of the

bottom, of the enclosure. The minimum dimension of air

openings shall not be less than 3 in (76.2 mm).

Combining spaces in different stories. The volumes of spaces

on different stories shall be considered as communicating

spaces where such spaces are connected by one or more

openings in doors or floors having a total minimum free area of

2 in.2/1,000 BTUH (44 cm2/kW) of total input rating of all

appliances.

An attic or crawl space may be considered a space that freely

communicates with the outdoors provided there are adequate

ventilation openings directly to outdoors. Openings MUST

remain open and NOT have any means of being closed off.

Ventilation openings to outdoors MUST be at least 1 square

inch of free area per 4,000 BTUH (5.5cm2/kW) of total input

rating 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 buildings

with unusually tight construction, additional air MUST be

provided using the methods described in section titled

Outdoor Combustion Air Method:

* Unusually tight construction is defined as Construction with:

1. Walls and ceilings exposed to the outdoors have a

continuous, 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 walt-ceiling joints, between

wall panels, at penetrations for plumbing, electrical and

gas lines, etc.

VentilationAir

Some provincial codes and local municipalities require ventilation

or make-up air be brought into the conditioned space as

replacement air. Whichever method is used, the mixed return air

temperature 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.

Ventingand CombustionAir Check

NOTE: If this installation replaces an existing furnace from a

commonly vented system, the original venting system may no

longer be sized to properly vent the attached appliances. An

improperly sized venting system may cause the formation of

condensate in the vent and the leakage or spillage of vent gases.

To make sure there is adequate combustion air for all appliances,

MAKE THE FOLLOWING CHECK.

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

Z228.1/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. Follow the 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 7)

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

Z228.1/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.

solvent cement that meets the requirements of ASTM D3138.

4) Refer to ASTM D2855 for general procedure to use for

cementing 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 the

furnace.

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. Furnace shall be installed so as to prevent the accumulation

of condensate.

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 Instructions For Horizontal

Vents).

The vertical vent pipe MUST be supported so that no weight

is allowed to rest on the combustion blower.

Exhaust vent piping or air inlet piping diameter MUST NOT

be reduced.

All exhaust vent piping from the furnace to termination

MUST slope upwards. A minimum of 1/4" per foot (6.4mm

per 304.8 mm) of run is required to properly return

condensate to the furnace drain system.

9. 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

elbows cannot be used, use two, 45° elbows when possible.

On horizontal runs the elbows can be slightly misatigned to

provide the correct slope.

10. All horizontal pipe runs MUST be supported at least every

five feet with galvanized strap or other rust resistant

material. NO sags or dips are permitted.

11. All vertical pipe runs MUST be supported every six feet

(1.8m) 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 to

supply 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.

16.

NOTE: In NO case can the piping be run in a chase where

temperatures can exceed 140 ° F(60°C). or where radiated

heat from adjacent surfaces would exceed 140° F(60°C).

14. The vent outlet MUST be installed to terminate in the same

atmospheric pressure zone as the combustion air inlet.

15. 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.

• 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 8 & Figure 9

are maintained.

Furnace applications with vertical vents requiring vent

diameter 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.

Combustion Air and Vent PipingInsulation

Guidelines

NOTE: Use closed cell, neoprene insulation or equivalent. If

Fiberglass or equivalent insulation is used it must have a vapor

barrier. Use R values of 7 up to 10' (3.1m), R-11 if exposure

exceeds 10' (3.1m). If Fiberglass insulation is used, exterior to the

structure, the pipe MUST be boxed in and sealed against

moisture.

Specifications are subject to change without notice.

440 01 105101

1. When the vent or combustion air pipe height above the roof

exceeds 30" (76.2mm), or if an exterior vertical riser is used

on a horizontal vent to get above snow levels, the exterior

portion MUST be insulated.

2. When combustion air inlet piping is installed above a

suspended 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,

humid spaces.

SizingCombustionAir and Vent Pipe

Consult Table3 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 or outlet side), and number of 90 ° elbows required. Two 45 °

elbows can be substituted for one 90 ° elbow. The elbow or elbows

used for vent termination outside the structure ARE counted,

including elbows needed to bring termination above expected

snow levels. The elbow inside the furnace on the *9MPX IS NOT

included in the count.

CondensateDrainTrap

This furnace removes both sensible and latent heat from the

products of combustion. Removal of the latent heat results in

condensation of the water vapor. The condensate is removed from

the furnace through the drains in the plastic transition and the vent

fitting. 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

furnace to properly prime the condensate trap with water. Until the

trap is fully primed, some condensate wilt be pulled into the

combustion blower. The furnace may cycle on the pressure switch

connected 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

condensate 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" (12.7mm) drain hose.

Remove the1/2 " (12.7mm) ID drain hose from either the gutter or

the white PVC tee trap. Using a funnel pour eight (8) ounces (257

mL) of water into 1/2" ID drain hose. Water wilt flow through the

drain hose and into the condensate drain trap. This will prime both

the vent and the transition sides of the trap. Reconnect the 1/2"

(12.7mm) 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" (15.9mm) O.D.] or vinyl tubing with a minimum inner diameter

(I.D.) of 5/8" (15.9mm) 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 1/4" (19.1 mm) per foot downward

slope toward the drain. 1/4" (19.1mm) per foot (304.8mm) is

recommended. Installation of an overflow line is recommended

when the 1/4" (19.1mm) per foot (304.8mm) slope to the

condensate drain cannot be maintained. A drain tube clip is

included in the furnace to prevent kinking/buckling of the drain

tube. The clip should remain in the furnace (between the door

switch plate and the blower shelf, Figure 10) during operation. See

Figure 20 for proper routing and installation of the overflow.

Representativedrawing only, some models may vary in appearance.

DO NOT trap the drain line in any other location than at the

condensate drain trap supplied with the furnace.

FROZEN AND BURST WATER PIPE HAZARD

Failure to follow this caution may result in property

damage.

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

local codes, or if no indoor floor drain is available. The

condensate pump must be approved for use with acidic

condensate.

A plugged condensate drain line or a failed condensate

pump will atlowcondensate to spill. If the furnace is installed

where a condensate spill could cause damage, it is

recommended that an auxiliary safety switch be installed to

prevent 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.

If the auxiliary switch in the condensate pump is used, the

furnace may shut down due to a blocked condensate line or

failed pump. To prevent frozen water pipes see the "Frozen

Water Pipe Hazard" Installation Section of this manual.

CondensateDrainTrap FreezeProtection

Special precautions MUST be made if installing furnace in an area

which may drop below freezing. This can cause improper

operation 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 115 volt, 40° F

self-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.

Connecting Tee Trap to Condensate

.........................................................................................................................................................Trap and 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.

1. 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.

2. 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

eliminate potential air lock problems.

3. The drain line from the tee trap is to be connected to the

furnace condensate trap drain line as shown above.

4. Condensate drain lines from a cooling coil may be

connected 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 rigid pipe or flexible tube.

Tube ID should NOT be less than 1/2, (12.7mm).

Connecting Vent and Combustion Air Piping

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal injury or death.

Cement or mechanically seal all joints, fittings, etc.

to prevent leakage of flue gases.

Refer to Figure 11 through Figure 19 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 coupling and gasket can be installed to the top

panel, or 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" (76.2mm) hole plug from the

furnace accessory bag and relocate to the open hole in the furnace

panel. Use four screws to seal the four mounting holes in the top

panel next to the hole plug. Drill four 7/64" (2.8mm) diameter holes

in the casing using the air intake coupling as the template.

The air intake coupling is sized for 2" (50.8mm) 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" (76.2mm) hole on 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" (76.2mm) hole plug from the loose parts bag and

relocate to the open hole in the furnace panel. (See Figure 11 or

Figure 20)

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 21)

Some installations require the vent fitting to be installed with

a 5° to 10° downward slope, (See Figure 11 through Figure 20)

FIRE HAZARD

Failure to follow this warning could result in

personal injury, death, 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 eyes.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal 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(0°C), use only low tempera-

ture 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

natural bristle brush or the dauber supplied with the cement. The

proper 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

allow primer to dry before applying cement.

3. Apply a thin coat of cement evenly in the socket. Quickly

apply 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

tapered 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.

ConnectingVent Pipes andTermination

(DirectVent)

NOTE: For direct vent applications, combustion air intake and vent

MUST terminate in the same atmospheric pressure zone. If

installation is in a cold climate (sustained temperatures 0°F and

belowfor 24ormoreconsecutivehours), increase the minimum distance

between vent pipe and air intake from 8" to 18".

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal injury or death.

Maintain a minimum of 36" (914.4mm) between

combustion air inlet and clothes dryer vent.

Terminate the combustion air intake as far as

possible from any air conditioner, heat pump,

swimming pool, swimming pool pumping, chlori-

nator or filtration unit.

1. Install all couplings, nipples and elbows using proper

procedures for Joining Pipe and Fittings and maintain

spacing between vent and combustion air piping as

indicated in Figure 22 through Figure 24.

44001 105101 Specifications are subject to change without notice.

2. Check hole sizes by making sure it is smaller than the

couplings or elbows that wilt 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" (19.1 mm) to 1" (25.4mm) and seat area between pipe

and wall.

4. Install the couplings, nipple and termination elbows as

shown and maintain spacing between vent and combustion

Under certain wind conditions some building materials may be

affected by flue products expelled in close proximity to

unprotected surfaces. Sealing or shielding of the exposed

surfaces with a corrosion resistant material (such as aluminum

sheeting) may be required to prevent staining or deterioration. The

protective material should be attached and sealed (if necessary) to

the building before attaching the vent terminal.

Specifications are subject to change without notice.

44001 105101

MultiVent TerminationClearances

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 26,

Figure 27, Figure 28, Figure 29, Figure 30 and Figure 24, but

Special Venting Requirements for Installations in Canada

Installation in Canada must conform to the requirements of CSA

B149 code. Vent systems must be composed of pipe, fittings,

cements, and primers listed to ULC S636. The special vent

fittings and accessory concentric vent termination kits and

accessory external drain trap have been certified to ULC S636

for use with those IPEX PVC vent components which have

been certified to this standard. In Canada, the primer and

cement must be of the same manufacturer as the vent system -

IPEX System 636, PVC/CPVC Primer, Purple Violet for Flue

Gas Venting and IPEX System 636(1)'M, PVC Cement for Flue

Gas Venting, rated Class IIA, 65 deg C. must be used with this

venting system - do not mix primers and cements from one

manufacturer with a vent system from a different manufacturer.

Follow the manufacturer's instructions in the use of primer and

cement and never use primer or cement beyond its expiration

date.

The safe operation, as defined by ULC S636, of the vent

system is based on following these installation instructions, the

vent system manufacturer's installation instructions, and proper

use of primer and cement. All fire stop and roof flashing used

with this system must be UL listed material. Acceptability under

Canadian standard CSA B149 is dependent upon full

compliance with all installation instructions. Under this

standard, it is recommended that the vent system be checked

once a year by qualified service personnel.

The authority having jurisdiction (gas inspection authority,

municipal building department, fire department, etc) should be

consulted before installation to determine the need to obtain a

permit.

Vertical & HorizontalTermination

Determine the pipe diameters required for the installation

from Table 4 and Figure 33.

Determine the best location for the termination kit. See

Figure32 for vertical termination or Figure36 for

horizontal termination. Roof termination is preferred since it

is less susceptible to damage, has reduced 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 snow and 4)

visible vent vapor.

GeneralDeratingRules

1. These furnaces may be used at full input rating when

installed at altitudes up to 2,000' (609.6m). When installed

above 2,000' (609.6m), the input must be decreased 2%

(Natural) or 4% (Propane) for each 1000' above sea level in

the USA. In Canada, the input rating must be derated 5%

(natural) or 10% (Propane) for each 1000' (304.8m) above

sea level. See Table 6 or Table 7 for required high altitude

input rate.

2. For operation with natural gas at altitudes above 2,000'

(609.6m), orifice change and/or manifold pressure

adjustments may be required for the gas supplied. First

consult your local gas supplier, then refer to Table 6 for

required pressure change and/or orifice change for high

altitudes.

3. For operation with Propane gas, gas orifices MUST be

changed and manifold pressure MUST be maintained as

per Table 7. Orifices can be ordered through our distributor.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal injury or death.

Do NOT draw return air from inside a closet or utility

room where furnace is located. Return air duct

MUST be sealed to furnace casing.

Installation

NOTE: Design and install the air distribution system to comply with

Air Conditioning Contractors of America manuals and/or NFPA

pamphlets 90A and 90B or other approved methods that conform

to local codes and good trade practices.

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

seal return air duct to furnace casing and terminate duct

outside furnace space.

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

side of furnace.

3. For furnaces installed without a cooling coil it is

recommended 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

manual. Manually operated dampers MUST be equipped with a

44001 105101

means to prevent furnace or air conditioning operation unless

damper is in the full heat or cool position.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in

personal injury or death.

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 installations 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 adjacent 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 under the

floor or through the attic.

1. For side connections using a 16" x 25" (406.4 x 635mm)

filter, cut out the embossed area shown in Figure 42. This

will provide a 141/2" x 221/2" (368.3 x 571.5mm)

approximate opening.

2. Bottom returns can be made by removing the knockout

panel in the furnace base. Do NOT remove knock-out

except for a bottom return.

Installation of locking-type dampers are recommended in all

branches, or in individual ducts to balance system's air flow.

Non-combustible, flexible duct connectors are

recommended 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

conditioning.

Insulation

1. Insulate ductwork installed in attics or other areas exposed

to outside temperatures with a minimum of 2" (50.8mm)

insulation and vapor barrier.

2. Insulate ductwork in indoor unconditioned areas with a

minimum of 1" (25.4mm) insulation with indoor type vapor

barrier.

Filters

A Filter must be used:

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

from the distributor.

Use either filter type:

• Washable, high velocity filters are based on a maximum

air flow rating of 600 FPM.

• Disposable, low velocity filters are based on a maximum

air flow of 300 FPM when used with filter grille.

• See Circulating Air Blower Data for additional data.

NOTE: Disposable, low velocity filters may be replaced with

washable, high velocity filter providing they meet the minimum

size areas. Washable, high velocity filters can be replaced ONLY

with same type and size.

AdditionOfAir Conditioning

When a refrigeration coil is used in conjunction with this unit, it must

be installed parallel with or on the discharge side of the unit to avoid

condensation on the heat exchanger. All furnaces are designed

with a break-away duct flange on the supply air side of the furnace.

This allows for installation in the horizontal right or downfiow

applications. The coil installation instructions must be consulted

for proper coil location and installation procedures. With a parallel

flow arrangement, dampers must be installed to prevent chilled air

from entering the furnace. If manually 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 of the furnace in order to

run the condensate drain line. Copper or plastic tubing may be

used for the condensate drain line.

DownflowFurnaceInstallation

Non-CombustibleFloor Installation

Fabricate a plenum to the dimensions given in Figure 4, for the

furnace outlet. Plenum should be flanged, approximately 3/4"

(19.1 mm)for support.

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.

CombustibleFloor Installation

FIRE HAZARD

Failure to install unit on noncombustible subbase

could result in personal injury, death, and/or

property damage.

Place furnace on noncombustible subbase on

downflow applications, unless installing on

non-combustible flooring.

The noncombustible subbase also must be used

on downflow application sin addition to a coil box

installation.

Subbase 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

discharge 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 restrictions

may occur.

The Subbase for Combustible Floors MUST be used when a

downflow furnace is set on a combustible floor, even when the

furnace is installed on a coil box.

1. Cut the opening in the floor according to Table 8. The hole in

the floor must be cut to the dimensions listed in Table 8

since the base is equipped with locating tabs that center the

base over the opening.

The opening in the base is 11/4" (31.8mm) shorter and 11/8"

(28.6mm) 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 8.

Note that the dimensions given are outside dimensions.

3. Set the base over the opening in the floor, centering it over

the opening. Fasten the base to the floor with screws or

nails. See Figure 47, Figure 48 and Figure 49.

4. Drop the plenum through the opening in the base. The

flange of the plenum should rest on top of the subbase.

Main BurnerFlameCheck

Allow the furnace to run approximately 10 minutes then inspect the

main burner. See Figure 52.

Check for the following (Figure 52):

• Stable and blue flames. Dust may cause orange tips or

wisps of yellow, but flames MUST NOT have solid, yellow

tips.

• Flames extending directly from burner into heat

exchanger.

• Flames do NOT touch sides of heat exchanger.

If any problems with main burner flames are noted, it may be

necessary to adjust gas pressures, or check for drafts.

NOTE: Flame sensor has a different orientation in all 050 models.

TemperatureRiseCheck

The blower speed MUST be set to give the correct air temperature

rise through the furnace as marked on the rating plate.

Temperature rise is the difference between supply and return air

temperatures.

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

registers 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.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in

personal injury or death.

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

installer dealer/contractor to select the proper speed taps for

the application when the unit is installed.

If it is necessary to change speeds, refer to steps below.

REDUCED FURNACE LIFE HAZARD

Failure to follow this caution may result in reduced

furnace life.

Use ONLY the blower motor speed taps insert

indicated in the Circulation Air Blower Data for

settin_ air temperature rise.

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

1. Refer to Furnace Wiring Diagram for location of the heating

and cooling speed taps located on the furnace control as

well as location of unused blower motor speed leads. Use

the chart (Table 9) to determine the blower motor speed

settings.

2. Change the heat or cool blower motor speed by removing

the motor lead from the "Heat" or "Cool" terminal and

replace it with the desired motor speed lead from the

"Unused Motor Lead" location. Connect the wire

previously removed from the "Heat" or "Cool" terminal to the

vacated "Unused Motor Lead" terminal.

3. If the same speed must be used for both heating and

cooling, 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.

44001 105101 Specifications are subject to change without notice.

Note: For motors with (4)speed leads, itwill be necessary to

tape off the terminal of the motor speed lead removed from

the "Heat" or "coor' terminal with electrical tape since an

open terminal wilt not be available at the "Unused Motor

Lead" location.

Continuous-Fan Operation using"G"

Energizing the "G" terminal on the furnace control provides

continuous fan operation. This is done by connecting the G

terminal of the thermostat to the G terminal on the furnace control.

When the FAN switch is turned from auto to ON the fan will operate

continuously at "HEAT" speed. EAC wilt be energized in this

mode.

NOTE: In heating, the fan will turn off during furnace ignition and

warm up then restart at heating speed.

Hard Wired ContinuousFan Operation

A terminal is provided on the furnace control board 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

10. Furnace Maintenance

taps. When the low speed blower lead is connected to this

terminal, this will provide low speed blower operation whenever

the other 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

operation.

Separatespeedselectionsfor Heat,Cool, and

ContinuousFan

Connect low speed lead from circulating motor to the "Cont."

terminal at the furnace control. The appropriate motor leads

should already be connected to the "Heat" and "coor' terminals.

If it is necessary to operate the heating speed and continuous

blower speed using the same blower speed, connect a jumper

between the "Heat" and "Cont." terminals on the furnace control.

Note: There should be only ONE motor lead going to the "Heat"

and "Cont." terminals.

FIRE, EXPLOSION, OR CARBON MONOXIDE

HAZARDS.

Failure to follow this warning could result in

personal injury, death and/or property damage.

It is recommended that the furnace be inspected

and serviced on an annual basis (before the heating

season) by a qualified service technician.

11. Sequence of Operation & Diagnostics

The following is the normal operating sequence.

Cooling(Y) Request:

24VAC signals applied to Y & G terminals of FCB (furnace control board)

• Cool motor speed is energized after 5 second Cool Fan On Delay time.

Y & G signals removed from FCB

• Cool motor speed is de-energized after 90 second Cool Fan Off Delay time.

ContinuousCirculatingFan(G) Request:

24 VAC signal is applied to G terminal of the FCB.

• Heat motor speed is energized without delay.

G signal removed from FCB.

• Heat motor speed is de-energized after 5 second delay.

NOTE 1) Furnace de-energizes the fan during the heat exchanger warm-up period on a call for Heating that occurs during a G request

unless a blower motor lead is connected to the Cont terminal on the FOB, in which case see NOTE 2).

NOTE 2) Heating or Cooling requests received during a Fan request cause the fan speed to change to the appropriate heat or cool

speed after the Fan on Delay time expires. The fan returns to continuous circulating speed after the selected Fan Off Delay time expires

following loss of the Heating or Cooling request.

ContinuousCirculatingFanHard-Wired (Cont) Request:

Field selected low speed motor tap installed on "CONT" terminal.

• Low speed is energized when power applied to furnace. Operates at this speed continuously while there are no other

blower demands from furnace control. Fan demands from furnace control for heat, cool or "G" will override hard-wired speed tap.

NOTE 3) EAC is NOT active for hard-wired mode but IS active for fan demands from furnace control for heat, cool and "G".

Heating(W) Request:

Heating (W) Request:

• 24 VAC signal applied to W terminal of FOB.

• Inducer motor turns on and the pressure switch(es) close(s).

• Following a 15 second prepurge delay, after the pressure switches closes, the igniter begins a 17 second warm-up.

• The gas valve is energized, the main burners light and flame is sensed.

• The igniter is de-energized after the main burners ignite.

• FOB will delay blower operation for the 30 seconds timed from the opening of the gas valve.

W signal removed from FCB.

• The gas valve de-energizes and the main burners go out.

• The inducer runs for a 15 second postpurge period.

• The fan stays at Heat speed.

• The fan de-energizes after the selected Heat Fan Off Delay time expires, timed from the gas valve de-energizing.

HUMIDIFIER - The 24V HUM is energized when the pressure switch closes on a call for heat. The 115V HUM (called HUM on Control)

is energized when the inducer is energized.

ELECTRONIC AIR CLEANER - EAC is energized when there isa blower speed call. It is NOT energized when blower operates in the

hard-wired continuous fan mode.

NOTE 4) If a new Heating request arrives while the control is waiting in the Heat Fan Off Delay time, the FCB will wait for the selected

Heat Fan Off Delay then start a new heating cycle as long as the heat call remains.

44001 105101 Specifications are subject to change without notice.

Heating Requestwith Gas ShutOff:

24 VAC signal applied to W terminal of FCB.

The FOB will attempt 4 cycles for ignition then go to soft lockout for 3 hours then try for ignition again as long as the heat call remains.

Power reset will clear lockout.

• Inducer motor turns on

• Following a 15 second prepurge delay, the igniter begins warm up.

• The igniter glows red-hot for 22 seconds, then turns off. The FOB flashes error code 6.

• The igniter stays off for 17 seconds, then begins to warm up again.
