cal components.

Use the following precautions during furnace installation and

servicing to protect the integrated control module from dam-

age. By putting the furnace, the control, and the person at

the same electrostatic potential, these steps will help avoid

exposing the integrated control module to electrostatic dis-

charge. This procedure is applicable to both installed and

non-installed (ungrounded) furnaces.

1. Disconnect all power to the furnace. Do not touch the

integrated control module or any wire connected to the

control prior to discharging your body’s electrostatic

charge to ground.

2. Firmly touch a clean, unpainted, metal surface of the

furnaces near the control. Any tools held in a person’s

hand during grounding will be discharged.

3. Service integrated control module or connecting wiring

following the discharge process in step 2. Use caution

not to recharge your body with static electricity; (i.e., do

not move or shu󰀪e your feet, do not touch ungrounded

objects, etc.). If you come in contact with an ungrounded

object, repeat step 2 before touching control or wires.

4. Discharge your body to ground before removing a new

control from its container. Follow steps 1 through 3 if

installing the control on a furnace. Return any old or

new controls to their containers before touching any

ungrounded object.

Location Requirements and Considerations

Your unit model type determines which installation proce-

dures must be used. For *M9S80 models, you must follow

instructions for Horizontal Left, Horizontal Right or Upow

installations only. These furnaces are not approved for Down-

ow installations.

*C9S80 models may be installed in the Downow position as

well as Horizontal Left & Horizontal Right positions.

WARNING

To prevent possible equipment damage, property damage,

personal injury, or death, the following bullet points must

be observed when installing this unit.

Follow the instructions listed below when selecting a furnace

location. Refer also to the guidelines provided in the Com-

bustion and Ventilation Air Requirements.

• Centrally locate the furnace with respect to the proposed

or existing air distribution system.

• Ensure the temperature of the return air entering the

furnace is between 55°F and 100°F when the furnace

is heating.

• Provisions must be made for venting combustion products

outdoors through a proper venting system. The length of

ue pipe could be a limiting factor in locating the furnace.

• Ensure adequate combustion air is available for

the furnace. Improper or insu󰀩cient combustion air

can expose building occupants to gas combustion

products that could include carbon monoxide. Refer to

Combustion and Ventilation Air Requirements section.

• The furnace must be level. If the furnace is to be set

on a oor that may become wet or damp at times,

the furnace should be supported above the oor on a

concrete base sized approximately 1-½” larger than the

base of the furnace.

• Ensure upow or horizontal furnaces are not installed

directly on carpeting, or any other combustible material.

The only combustible material allowed is wood.

• Exposure to contaminated combustion air will result in

safety and performance-related problems. Do not install

the furnace where the combustion air is exposed to the

following substances:

chlorinated waxes or cleaners

chlorine-based swimming pool chemicals

water softening chemicals

deicing salts or chemicals

carbon tetrachloride

halogen type refrigerants

cleaning solutions (such as perchloroethylene)

printing inks

paint removers

varnishes

hydrochloric acid

cements and glues

antistatic fabric softeners for clothes dryers

and masonry acid washing materials

• If the furnace is used in connection with a cooling unit,

install the furnace upstream or in parallel with the cooling

unit coil. Premature heat exchanger failure will result if

the cooling unit coil is placed ahead of the furnace.

• For vertical applications, the minimum cooling coil

width shall not be less than furnace width minus 1”.

Additionally, a coil installed above an upow furnace or

under a counterow furnace may be the same width as

the furnace or may be one size larger than the furnace.

Example: a “C” width coil may be installed with a “B”

width furnace.

• For upow applications, the front of the coil and furnace

must face the same direction.

• If the furnace is installed in a residential garage, position

the furnace so that the burners and ignition source are

located not less than 18 inches (457 mm) above the oor.

Protect the furnace from physical damage by vehicles.

• If the furnace is installed horizontally, the furnace access

doors must be vertical so that the burners re horizontally

into the heat exchanger. Do not install the unit with the

access doors on the “up/top” or “down/bottom” side of

the furnace.

• Do not connect this furnace to a chimney ue that serves

a separate appliance designed to burn solid fuel.

• Counterow installation over a noncombustible oor.

Before setting the furnace over the plenum opening,

ensure the surface around the opening is smooth and

level. A tight seal should be made between the furnace

base and floor by using a silicon rubber caulking

compound or cement grout.

• Counterow installation over a combustible oor. If

installation over a combustible oor becomes necessary,

use an accessory subbase (see Specication Sheet

applicable to your model for details). A special accessory

subbase must be used for upright counterow unit

installations over any combustible material including

wood. Follow the instructions with the subbase for proper

installations.

• Do not install the furnace directly on carpeting, tile, or

other combustible material other than wood ooring.

(NOTE: The subbase will not be required if an air

conditioning coil is installed between the supply air

opening on the furnace and the oor. The air conditioning

coil must be downstream from the heat exchanger of

the furnace.

flue gas must be supplied. Most homes require outside air be

supplied into the furnace area.

Improved construction and additional insulation in build-

ings have reduced heat loss by reducing air inltration and

escape around doors and windows. These changes have

helped in reducing heating/cooling costs but have created

a problem supplying combustion and ventilation air for gas

red and other fuel burning appliances. Appliances that pull

air out of the house (clothes dryers, exhaust fans, replaces,

etc.) increase the problem by starving appliances for air.

House depressurization can cause back drafting or improp-

er combustion of gas-red appliances, thereby exposing

building occupants to gas combustion products that could

include carbon monoxide.

If this furnace is to be installed in the same space with other

gas appliances, such as a water heater, ensure there is an

adequate supply of combustion and ventilation air for all ap-

pliances. Refer to the latest edition of the National Fuel Gas

Code NFPA 54/ANSI Z223.1 or CAN/CSA B149 Installation

Codes or applicable provisions of the local building codes

for determining the combustion air requirements for the ap-

pliances.

This furnace must use indoor air for combustion. It cannot be

installed as a direct vent (i.e., sealed com bustion) furnace.

Most homes will require outside air be supplied to the fur-

nace area by means of ventilation grilles or ducts connecting

directly to the outdoors or spaces open to the outdoors such

as attics or crawl spaces.

Category I Venting (Vertical Venting)

WARNING

To prevent possible personal injury or death due to asphyx-

iation, this furnace must be Category I vented. Do not vent

using Category III venting.

Category I Venting is venting at a non-positive pressure. A

furnace vented as Category I is considered a fan-assisted

appliance and the vent system does not have to be “gas

tight”. NOTE: Gas furnaces with induced draft blowers draw

products of combustion through a heat exchanger allowing,

in some instances, common venting with natural draft appli-

ances (i.e. water heaters). All installations must be vented

in accordance with National Fuel Gas Code NFPA 54/ANSI

Z223.1 - latest edition.

NOTE: The vertical height of the Category I venting system

must be at least as great as the horizontal length of the vent-

ing system.

WARNING

To prevent possible personal injury or death due to asphyx-

iation, common venting with other manufacturer’s induced

draft appliances is not allowed.

The minimum vent diameter for the Category I venting sys-

tem is as shown:

MINIMUM VENT

MODEL

Under some conditions, larger vents than those shown

above may be required or allowed. When an existing fur-

nace is removed from a venting system serving other appli-

ances, the venting system may be too large to properly vent

the remaining attached appliances.

Furnaces are shipped with the induced draft blower dis-

charging from the top of the furnace. (“Top” is as viewed for

an upow installation.) The induced draft blower on *M9S80

models can be rotated 90 degrees for Category I venting.

For furnaces installed vertically or horizontally, a four-inch

single wall pipe can be used to extend the induced draft

blower outlet ½” beyond the furnace cabinet. On *M9S80

furnaces installed upow or horizontally with left side down,

the draft inducer may be rotated to discharge from the right

side of the cabinet. When rotating the inducer a chimney

transition bottom kit (part # 4053501S) is needed for prop-

er alignment of the inducer outlet and the vent exit hole in

the side of the cabinet. The inducer may NOT be rotated on

*C9S80 model furnaces regardless of installation position.

THIS PRODUCT IS NOT DESIGNED FOR COUNTER-

CLOCKWISE INDUCED DRAFT BLOWER ROTATION.

Vent the furnace in accordance with the National Fuel Gas

Code NFPA 54/ANSI Z223.1 - latest edition.

WARNING

Never allow the products of combustion, including carbon

monoxide, to enter the return ductwork or circulation air

supply.

Masonry Chimneys

WARNING

Possibility of property damage, personal injury or death

damaging condensation can occur inside masonry chimneys

when a single fan-assisted Category I appliance (80% AFUE

furnace) is vented without adequate dilution air. Do not

connect an 80% furnace to a masonry chimney unless the fur-

nace is common vented with a draft hood equipped appliance

or the chimney is lined with a metal liner or Type B metal

vent. All installations using masonry chimneys must be sized

in accordance with appropriate venting tables. If an 80% fur-

naces common vented with a draft hood equipped appliance,

the potential for condensation damage may still exist with

extremely cold conditions, long vent connectors, exterior

chimneys, or any combination of these conditions. The risk

of condensation damages is best avoided by using masonry

chimney as a pathway for properly sized metal liner or Type B

metal vent.

Masonry Chimney Terminations

A masonry chimney used as a vent for gas red equipment

must extend at least three feet above the highest point

where it passes through the roof. It must extend at least two

feet higher than any portion of a building within a horizontal

distance of 10 feet. In addition, the chimney must terminate

at least three feet above any forced air inlet located within

10 feet. The chimney must extend at least ve above the

highest connected equipment draft hood outlet or ue collar.

damaged by heat from the burners or by the rotation of

the fan. Also conrm that wiring location will not interfere

with l ter removal or other maintenance.

IMPORTANT NOTE: To avoid possible equipment malfunc-

tion, route the low voltage wires to avoid interference with

lter removal or other maintenance.

WARNING

HIGH VOLTAGE!

To avoid risk of injury, electrical shock or death,

the furnace must be electrically grounded in

accordance with local codes or in their absence,

with the latest edition of the National Electric

Code.

To ensure proper unit grounding, the ground wire should run

from the furnace ground screw located inside the furnace

junction box all the way back to the electrical panel. NOTE:

Do not use gas piping as an electrical ground. To conrm

proper unit grounding, turn o󰀨 the electrical power and per-

form the following check.

1. Measure resistance between the neutral (white)

connection and one of the burners.

2. Resistance should measure 10 ohms or less.

This furnace is equipped with a blower door interlock switch

which interrupts unit voltage when the blower door is opened

for servicing. Do not defeat this switch.

Gas Supply and Piping

The furnace rating plate includes the approved furnace gas

input rating and gas types. The furnace must be equipped to

operate on the type of gas applied. This includes any con-

version kits required for alternate fuels and/or high altitude.

CAUTION

To prevent unreliable operation or equipment damage, the

inlet gas supply pressure must be as specified on the unit

rating plate with all other household gas fired appliances

operating.

Inlet gas supply pressures must be maintained within the

ranges specied in the following table. The supply pressure

must be constant and available with all other household gas

red appliances operating. The minimum gas supply pres-

sure must be maintained to prevent unreliable ignition. The

maximum must not be exceeded to prevent unit overring.

NOTE: Do not remove the gas valve inlet plug before the

gas line is installed. Replace if water or debris has been

introduced.

Natural Gas Minimum: 4.5" w.c. Maximum: 10.0" w.c.

Propane Gas Minimum: 11.0" w.c. Maximum: 13.0" w.c.

INLET GAS SUPPLY PRESSURE

NOTE: Adjusting the minimum supply pressure below the

limits in the above table could lead to unreliable ignition.

Gas input to the burners must not exceed the rated input

shown on the rating plate. Overring of the fur nace can re-

sult in premature heat exchanger failure. Gas pressures in

excess of 13 inch es water column can also cause perma-

nent damage to the gas valve.

At all altitudes, the manifold pressure must be within 0.3

inches w.c. of that listed in the Specication Sheet applica-

ble to your model for the fuel used. At all altitudes and with

either fuel, the air tempera ture rise must be within the range

listed on the furnace nameplate. Should this appliance be

converted to LP, refer to the instructions included in the fac-

tory authorized LP conversion kit.

High Altitude Derate

When this furnace is installed at high altitude, the appropri-

ate High Altitude orice kit must be applied. This is required

due to the natural reduction in the density of both the gas

fuel and combustion air as altitude increases. The kit will

provide the proper design certied input rate within the spec-

ied altitude range.

High altitude kits are purchased according to the installation

altitude and usage of either natural or propane gas. Consult

the furnace Specication Sheet for appropriate kits.

Do not derate the furnace by adjusting the manifold pressure

to a lower pressure than specied on the furnace rating plate.

The combination of the lower air density and a lower manifold

pressure will prohibit the burner orice from drawing the prop-

er amount of air into the burner. This may cause incomplete

combustion, ashback, and possible yellow tipping.

In some areas the gas supplier may articially derate the

gas in an e󰀨ort to compensate for the e󰀨ects of altitude.

If the gas is articially derated, the appropriate orice size

must be determined based upon the BTU/ft

content of the

derated gas and the altitude. Refer to the National Fuel Gas

Code, NFPA 54/ANSI Z223.1, and information provided by

the gas supplier to determine the proper orice size.

A di󰀨erent pressure switch may be required at high altitude

regardless of the BTU/ft

content of the fuel used. Consult

the furnace Specication Sheet for pressure switch.

WARNING

Possible property damage, personal injury or death may

occur if the correct conversion kits are not installed. The

appropriate kits must be applied to ensure safe and proper

furnace operation. All conversions must be performed by a

qualified installer or service agency.

Consult the furnace Specication Sheet for appropriate

manufacturer’s kits for propane gas and/or high altitude in-

stallations. The indicated kits must be used to insure safe

and proper furnace operation. All conversions must be per-

formed by a qualied installer, or service agency.

Propane Gas Conversion

WARNING

Possible property damage, personal injury or death may

occur if the correct conversion kits are not installed. The

appropriate kits must be applied to ensure safe and proper

furnace operation. All conversions must be performed by a

qualified installer or service agency.

This unit is congured for natural gas. The appropriate man-

ufacturer’s propane gas conversion kit must be applied for

propane gas installations.

If converting to LP gas, it is recommended that an LPLP0* kit

also be installed. The use of this kit will prevent the furnace

from ring when the LP gas supply pressure is too low to

support proper combustion.

Gas Valve

This unit is equipped with a 24 volt gas valve controlled

during furnace operation by the integrated control module.

As shipped, the valve is congured for natural gas. The valve

is eld convertible for use with propane gas by replacing the

regulator spring with a propane gas spring from an appro-

priate manufacturer’s propane gas conversion kit. Taps for

measuring the gas supply pressure and manifold pressure

are provided on the valve.

The gas valve has a manual ON/OFF control located on the

valve itself. This control may be set only to the “ON” or “OFF”

position. Refer to the lighting instructions label or Startup

Procedure & Adjustment for use of this control during start

up and shut down periods.

Gas Piping Connections

When sizing gas lines, be sure to include all appliances

which will operate simultaneously.

The gas piping supplying the furnace must be properly sized

based on the gas ow required, specic gravity of the gas,

and length of the run. The gas line installation must comply

with local codes, or in their absence, with the latest edition of

the National Fuel Gas Code, NFPA 54/ANSI Z223.1.

To connect the furnace to the building’s gas piping, the in-

staller must supply a ground joint union, drip leg, manual

shuto󰀨 valve, and line and ttings to connect to gas valve.

In some cases, the installer may also need to supply a tran-

sition piece from ½” pipe to a larger pipe size.

The following stipulations apply when connecting gas piping.

• Gas piping must be supported external to the furnace

cabinet so that the weight of the gas line does not distort

the burner rack, manifold or gas valve.

• Use black iron or steel pipe and ttings for the building

piping.

• Use pipe joint compound on male threads only. Pipe

joint compound must be resistant to the action of the

fuel used.

• Use ground joint unions.

• Install a drip leg to trap dirt and moisture before it can

enter the gas valve. The drip leg must be a minimum of

three inches long.

• Use two pipe wrenches when making connection to

the gas valve to keep it from turning. The orientation of

the gas valve on the manifold must be maintained as

shipped from the factory.

• Install a manual shuto󰀨 valve between the gas meter and

unit within six feet of the unit. If a union is installed, the

union must be downstream of the manual shuto󰀨 valve,

between the shuto󰀨 valve and the furnace.

• Tighten all joints securely.

• Connect the furnace to the building piping by one of the

following methods:

– Rigid metallic pipe and ttings.

– Semi-rigid metallic tubing and metallic ttings. Alu-

minum alloy tubing must not be used in exterior loca-

tions.

– Use listed gas appliance connectors in accordance

with their instructions. Connectors must be fully in the

same room as the furnace.

– Protect connectors and semi-rigid tubing against

physical and thermal damage when installed. Ensure

aluminum-alloy tubing and connectors are coated to

protect against external corrosion when in contact

with masonry, plaster, or insulation, or subjected to re-

peated wetting by liquids such as water (except rain

water), detergents, or sewage.

Gas Piping Checks

Before placing unit in operation, leak test the unit and gas

connections.

WARNING

To avoid the possibility of explosion or fire, never use a

match or open flame to test leaks.

Check for leaks using an approved chloride-free soap and

water solution, an electronic combustible gas detector, or

other approved testing methods.

WARNING

To prevent property damage or personal injury due to fire,

the following instructions must be performed regarding gas

connections, pressure testing, location of shutoff valve and

installation of gas piping.

NOTE: Never exceed specied pressures for testing. Higher

pressure may cause gas valve failure.

Disconnect this unit and shuto󰀨 valve from the gas supply

piping system before pressure testing the supply piping sys-

tem with pressures in excess of ½ psig (3.48 kPa).

This unit must be isolated from the gas supply system by

closing its manual shuto󰀨 valve before pressure testing of

gas supply piping system with test pressures equal to or less

than ½ psig (3.48 kPa).

Propane Gas Tanks and Piping

A gas detecting warning system is the only reliable way to

detect a propane gas leak. Rust can reduce the level of

odorant in propane gas. Do not rely on your sense of smell.

Contact a local propane gas supplier about installing a gas

detecting warning system. If the presence of gas is suspect-

ed, follow the instructions on Page 3 of this manual.

All propane gas equipment must conform to the safety stan-

dards of the National Board of Fire Underwriters, NBFU

Manual 58.

For satisfactory operation, propane gas pressure must be

10 inch WC at the furnace manifold with all gas appli ances

in operation. Maintaining proper gas pressure depends on

three main factors:

1. Vaporization rate, depending on temperature of the

liquid, and “wetted surface” area of the con tainer or

containers.

2. Proper pressure regulation (Two-stage regulation is

recommended for both cost and e󰀩ciency).

3. Pressure drop in lines between regulators, and between

second stage regulator and the appliance. Pipe size

will depend on length of pipe run and total load of all

appliances.

Complete information regarding tank sizing for vaporiza tion,

recommended regulator settings, and pipe sizing is avail-

able from most regulator manufacturers and propane gas

suppliers.

Use a pipe thread compound that is approved for natural

gas and LP Gas.

A duct system must be installed in accordance with Stan-

dards of the National Board of Fire Underwriters for the In-

stallation of Air Conditioning, Warm Air Heating and Ventilat-

ing Systems. Pamphlets No. 90A and 90B.

A closed return duct system must be used, with the return

duct connected to the furnace. NOTE: Ductwork must nev-

er be attached to the back of the furnace. For installations

requiring more than 1800 CFM, use a bottom return or two

sided return. Supply and return con nections to the furnace

may be made with exible joints to reduce noise transmis-

sion. To prevent the blower from inter fering with combustion

air or draft when a central return is used, a connecting duct

must be installed between the unit and the utility room wall.

A room, closet, or alcove must not be used as a return air

chamber.

When the furnace is used in connection with a cooling unit,

the furnace should be installed in parallel with or on the

upstream side of the cooling unit to avoid condensa tion in

the heating element. With a parallel ow arrange ment, the

dampers or other means used to control the ow of air must

be adequate to prevent chilled air from entering the furnace

and, if manually operated, must be equipped with means to

prevent operation of either unit unless the damper is in the

full heat or cool position.

When the furnace is installed without a cooling coil, it is rec-

ommended that a removable access panel be provided in

the outlet air duct. This opening shall be accessible when

the furnace is installed and shall be of such a size that the

heat exchanger can be viewed for visual light inspection

or such that a sampling probe can be inserted into the air

stream. The access panel must be made to prevent air leaks

when the furnace is in operation.

When furnace duct(s) supply air outside the space contain-

ing the furnace, a return air duct must terminate in the same

space as the supply duct and be sealed to the furnace casing.

When the furnace is heating, the temperature of the return

air entering the furnace must be between 55°F and 100°F.

Checking Duct Static

Refer to your furnace rating plate for the maximum ESP (ex-

ternal duct static) rating.

Total external static refers to static pressure created by all

components external to the furnace cabinet. Cooling coils,

lters, ducts, grilles, registers must all be considered when

reading your total external static pressure. The supply duct

pressure must be read between the furnace and the cool-

ing coil. This reading is usually taken by removing the “A”

shaped block o󰀨 plate from the end on the coil; drilling a

test hole in it and reinstalling the block o󰀨 plate. Take a duct

static reading at the test hole. Tape up the test hole after

your test is complete. The negative pressure must be read

between the lter and the furnace blower.

Too much external static pressure will result in insu󰀩cient air

that can cause excessive temperature rise. This can cause

limit switch tripping and heat exchanger failure.

To determine total external duct static pressure, proceed as

follows:

4. With clean lters in the furnace, use a manometer to

measure the static pressure of the return duct at the

inlet of the furnace. (Negative Pressure)

5. Measure the static pressure of the supply duct. (Positive

Pressure)

6. The di󰀨erence between the two numbers is .4” w.c.

Example:

static reading from return duct = -.1” w.c.

static reading from supply duct = .3” w.c.

total external static pressure on this system = .4” w.c.

NOTE: Both readings may be taken simultaneously and

read directly on the manometer if so desired. If an air

conditioner coil or Electronic Air Cleaner is used in con-

junction with the furnace, the readings must also include

these components, as shown in the following drawing.

7. Consult proper tables for the quantity of air.

If the total external static pressure exceeds the maximum

listed on the furnace rating plate, check for closed dampers,

registers, undersized or poorly laid out duct work.

Filters - Read This Section Before Installing The

Return Air Ductwork

Filters must be used with this furnace. Discuss lter main-

tenance with the building owner. Filters do not ship with this

furnace, but must be provided by the installer. Filters must

comply with UL900 or CAN/ULCS111 standards. Damage or

repairs due to the installation of the furnace without lters is

not covered under the warranty.

Upright Installations

Depending on the installation and/or customer preference,

di󰀨ering lter arrangements can be applied. Filters can be

installed in the central return register or a side panel external

lter rack kit (upows), or the ductwork above a downow

furnace. As an alternative, a media air lter or electronic air

cleaner can be used as the primary lter.

Horizontal Installations

Filters must be installed in either the central return register

or in the return air duct work.

Circulation Air Filters

Figure 6 Figure 7

Figure 8 Figure 9

Figure 10

One of the most common causes of a problem in a forced

air heating system is a blocked or dirty lter. Circulating air

lters must be inspected monthly for dirt accumulation and

replaced if necessary. Failure to maintain clean lters can

cause premature heat exchanger failure.

A new home may require more frequent replacement until all

construction dust and dirt is removed.

24 Volt Thermostat Wiring

Important Note: Wiring routing must not interfere with circu-

lator blower operation, lter removal or routine maintenance.

Low voltage connections can be made through either the

right or left side panel. Thermostat wiring entrance holes

are located in the blower compartment. The following gure

shows connections for a “heat/cool system”.

This furnace is equipped with a 40 VA transformer to facili-

tate use with most cooling equipment. Consult the wiring di-

agram, located on the blower compartment door, for further

details of 115 Volt and 24 Volt wiring.

Fossil Fuel Applications

This furnace can be used in conjunction with a heat pump

in a fossil fuel application. A fossil fuel application refers to

a combined gas furnace and heat pump installation which

uses an outdoor temperature sensor to determine the most

cost e󰀩cient means of heating (heat pump or gas furnace).

A heat pump thermostat is required to properly use a sin-

gle-stage furnace in conjunction with a heat pump. Refer to

the fossil fuel kit installation instructions for additional ther-

mostat requirements.

Strictly follow the wiring guidelines in the fossil fuel kit instal-

lation instructions. All furnace connections must be made

to the furnace two-stage integrated control module and the

“FURNACE” terminal strip on the fossil fuel control board.

Twinning

Two furnaces of the same model may be twinned. The in-

tegrated control board has a 3/16” terminal labeled “TWIN”

located beside the low voltage thermostat connection strip.

Twinning allows simultaneous operation of two furnaces and

forces the indoor blower motors of each furnace to operate

synchronously into a common duct system. Using the twin-

ning function will require only eld installed wiring with no

external kits or parts. The staging and speed tap options

must be set the same on both furnaces.

NOTE: Each furnace must be connected to it’s own 115 VAC

power supply. The L1 connection to each furnace must be in

phase (connected to circuit breakers on the same 115 VAC

service panel phase leg). To verify that the furnaces are in

phase, check from L1 to L1 on each furnace with a voltme-

ter. If the furnaces are in phase, the voltage between both

furnaces will be ZERO.

115 Volt Line Connection of Accessories (Humidifi-

er and Electronic Air Cleaner)

The furnace integrated control module is equipped with line

voltage accessory terminals for controlling power to an op-

tional eld-supplied humidier and/or electronic air cleaner.

The accessory load specications are noted in the chart:

Humidifier

1.0 Amp maximum at 120 VAC

Electronic Air Cleaner

1.0 Amp maximum at 120 VAC

Turn OFF power to the furnace before installing any acces-

sories. Follow the humidier or air cleaner manufacturers’ in-

structions for locating, mounting, grounding, and controlling

these accessories. Accessory wiring connections are to be

made through the 1/4” quick connect terminals provided on

the furnace integrated control module. The humidier and

electronic air cleaner hot terminals are identied as HUM H

and EAC H. The humidier and electronic air cleaner neutral

terminals are identied as NEUTRAL. All eld wiring must

conform to applicable codes. Connections should be made

as shown.

If it is necessary for the installer to supply additional line

voltage wiring to the inside of the furnace, the wiring must

conform to all local codes, and have a minimum temperature

rating of 105°C. All line voltage wire splices must be made

inside the furnace junction box.

The integrated control module humidier terminal (HUM

H) is energized with 115 volts whenever the induced draft

blower is energized. The integrated control module electron-

ic air cleaner terminal (EAC H) is energized with 115 volts

whenever the circulator blower is energized. This terminal

can also be used to provide 115 volt power to a humidier

transformer. The remaining primary transformer wire would

be connected to the Line N on the control board.

WARNING

To avoid electric shock, injury or death, discon-

nect electrical power before performing any

maintanence. If you must handle the igniter, handle

with care. Touching the igniter element with bare

fingers, rough handling or vibration could damage

the igniter resulting in premature failure. Only a

qualified servicer should ever handle the igniter.

Annual Inspection

The furnace should be inspected by a qualied installer, or

service agency at least once per year. This check should be

performed at the beginning of the heating season. This will

ensure that all furnace components are in proper working or-

der and that the heating system functions appropriately. Pay

particular attention to the following items. Repair or service

as necessary.

• Flue pipe system. Check for blockage and/or leakage.

Check the outside termination and the connections at

and internal to the furnace.

• Heat exchanger. Check for corrosion and/or buildup

within the heat exchanger passageways.

• Burners. Check for proper ignition, burner ame, and

ame signal.

• Wiring. Check electrical connections for tightness and/

or corrosion. Check wires for damage.

• Filters.

Filters

CAUTION

To ensure proper unit performance, adhere to the filter

sizes given in the recommended Minimum Filter Size Table or

Specification Sheet applicable to your model.

Filter Maintenance

Improper lter maintenance is the most common cause of in-

adequate heating or cooling performance. Filters should be

cleaned (permanent) or replaced (disposable) as required.

Filter Removal

Depending on the installation, di󰀨ering lter arrangements

can be applied. Filters can be installed in either the cen-

tral return register or a side panel external lter rack (upow

only). A media air lter or electronic air cleaner can be used

as an alternate lter. Follow the lter sizes given in the Rec-

ommended Minimum Filter size table to ensure proper unit

performance.

To remove lters from an external lter rack in an upright up-

ow installation, follow the directions provided with external

lter rack kit.

Horizontal Unit Filter Removal

Filters in horizontal installations are located in the central

return register or the ductwork near the furnace.

To remove:

1. Turn OFF electrical power to furnace.

2. Remove filter(s) from the central return register or

ductwork.

3. Replace lter(s) by reversing the procedure for removal.

4. Turn ON electrical power to furnace.

Media Air Filter or Electronic

Air Cleaner Removal

Follow the manufacturer’s directions for service.

Burners

Visually inspect the burner ames periodically during the

heating season. Turn on the furnace at the thermostat and

allow several minutes for ames to stabilize, since any dis-

lodged dust will alter the ames normal appearance. Flames

should be stable, quiet, soft, and blue (dust may cause or-

ange tips but they must not be yellow). They should extend

directly outward from the burners without curling, oating, or

lifting o󰀨. Flames must not impinge on the sides of the heat

exchanger ring tubes.

Induced Draft and Circulator Blowers

The bearings in the induced draft blower and circulator blow-

er motors are permanently lubricated by the manufacturer.

No further lubrication is required. Check motor windings for

accumulation of dust which may cause overheating. Clean

as necessary.

Flame Sensor (Qualified Servicer Only)

Under some conditions, the fuel or air supply can create a

nearly invisible coating on the ame sensor. This coating

acts as an insulator causing a drop in the ame sense sig-

nal. If the ame sense signal drops too low the furnace will

not sense ame and will lock out. The ame sensor should

be carefully cleaned by a qualied servicer using steel wool.

Following cleaning, the ame sense signal should be as in-

dicated in the Specications Sheet.

Flue Passages (Qualified Servicer Only)

The heat exchanger ue passageways should be inspected

at the beginning of each heating season.

Before Leaving an Installation

• Cycle the furnace with the thermostat at least three

times. Verify cooling and fan only operation.

• Review the Owner’s Manual with the homeowner and

discuss proper furnace operation and maintenance.

• Leave literature packet near furnace.

Repair and Replacement Parts

• When ordering any of the listed functional parts, be sure

to provide the furnace model, manufacturing, and serial

numbers with the order.

• Although only functional parts are shown in the parts

list, all sheet metal parts, doors, etc. may be ordered

by description.

• Parts are available from your distributor.
