I mportant facts
Your furnace must have adequate surrounding airflow for
efficient combustion and safe ventilation. Do not enclose
it in an airtight room or “seal” it behind solid doors.
Tominimizethepossibilityofseriouspersonalinjury,fire,
furnace damage, or improper operation;
carefully follow
these safety rules:
• Keep the area around your furnace free of combustible
materials, gasoline, and other flammable liquids and
vapors.
3
• Do not cover the furnace, store trash or debris near it, or
in any way block the flow of fresh air to the unit.
• Combustion air must be clean and uncontaminated with
chlorineorfluorine.Thesecompoundsarepresentinmany
products around the home, such as: water softener salts,
laundrybleaches,detergents,adhesives, paints, varnishes,
paint strippers, waxes, and plastics.
Make sure the combustion air for your furnace does not
contain any of these compounds. The combustion air dur-
ingremodelingmustbefreshanduncontaminated.Ifthese
compounds are burned in your furnace, the heat exchang-
ers and metal vent system may deteriorate.
• A furnace installed in an attic or other insulated space
mustbekeptfreeandclearofinsulatingmaterial.Examine
the furnace area when installing the furnace or adding
more insulation. Some materials may be combustible.
NOTE:
Do not use this furnace if any part has been under
water. Immediately call a qualified service technician to
inspect the furnace and to replace any part of the control
system and any gas control which has been under water.
NOTE:
The qualified installer or agency must use only
factory-authorized replacement parts, kits, and accesso-
ries when modifying this product.
This furnace contains safety devices which must be man-
ually reset or replaced. If the furnace is left unattended for
an extended period of time, have it checked periodically
for proper operation. This precaution will prevent prob-
lems associated with no heat, such as frozen water pipes,
etc. See “BeforeYou Request a Service Call” section in
this manual.
Safety considerations
Installing and servicing heating equipment can be hazard-
ousduetogasandelectricalcomponents.Onlytrainedand
qualified personnel should install, repair, or service heat-
ing equipment.
Untrained personnel can perform basic maintenance func-
tions such as cleaning and replacing air filters. All other
operations must be performed by trained service person-
nel. Observe safety precautions in this manual, on tags,
and on labels attached to the furnace and other safety pre-
cautions that may apply.
Recognize safety information: This is the safety-alert
symbol .When you see this symbol on the furnace and
in instructions or manuals, be alert to the potential for per-
sonal injury.
Understand the signal words — DANGER, WARNING,
andCAUTION.Thesewordsareusedwiththesafety-alert
symbol. DANGER identifies the most serious hazards
which
will result in severe personal injury or death.
WARNING signifies hazards which could result in per-
sonalinjury ordeath.CAUTIONisused to identifyunsafe
practices which would result in minor personal injury or
product and property damage.
Starting your furnace
Insteadofacontinuouslyburningpilotflame,yourfurnace
uses an automatic hot surface ignition system to light the
burners each time the thermostat signals the furnace to
start. Follow these important safeguards:
• Neverattempttomanuallylighttheburnerswithamatch
or other source of flame.
4
• Read and follow the operating instructions on the fur-
nace, especially the item that reads as follows:
Wait 5 minutes to clear out any gas. Then smell for gas,
includingnear the floor.If you smell gas,
STOP! Follow
“B” in the safety information above on this label. If you
don't smell gas, go to the next step.
• If a suspected malfunction occurs with your gas control
system, such as the burners do not light when they should,
refer to the shutdown procedures on the furnace, or in the
next section, to turn off your system, then call your dealer
as soon as possible.
•
Check Air Filter: Before attempting to start your fur-
nace, be sure the furnace filter is clean and in place. (See
the maintenance section of this manual.) Then proceed as
follows:
WARNING
Should overheating occur, or the gas valve fail
to shut off the gas supply, turn off the manual
gas valve (See Fig. 6) to the furnace BEFORE
turning off the electrical supply. A failure to
follow this warning could result in a fire or ex-
plosion, and personal injury or death.

delay of approximately 45 sec, the furnace blower is
switched on.
NOTE:
Ifthemainburnersfailtoignite,thefurnacecontrol
system will go through 3 more ignition cycles. Then, if
burners fail to ignite, the system will lockout. If lockout
occurs, or the blower doesn't come on—shut down your
furnace and call your dealer for service.
12. Set your thermostat to the temperature that satisfies
your comfort requirements. SUGGESTION: Setting
the thermostat back a few degrees—and compensat-
ing for the difference with warmer clothing—can
make a big difference in your fuel consumption on
extremely cold days. The few degrees at the top of
your thermostat “comfort level” are the most costly
degrees to obtain.
When the room temperature drops below the temperature
selectedon thethermostat,the furnace willbeswitched on
automatically. When the room temperature reaches the
degree selected on the thermostat, the furnace will be
switched off automatically.
Some thermostats have a “fan” mode with 2 selections:
AUTO or ON. When set on AUTO, the furnace blower
cycles on and off, controlled by the thermostat. In the ON
position, the furnace blower runs continuously except for
a 45-sec delay at the “call for heat.” This keeps the tem-
perature level in your home more evenly balanced. It also
continuously filters the indoor air.
Shutting down your furnace
Should you ever suspect a malfunction in your furnace,
you will need to turn the furnace off. The following pro-
cedures must be followed:
1. Set your room thermostat to the lowest temperature
setting. (See Fig. 16.)
2. Close the external manual gas valve. (See Fig. 6.)
3. Turn OFF the electrical power to your furnace.
(See Fig. 17.)

4. Remove the control access door on your furnace.
(See Fig. 8.) Removal of the blower access door is not
required.
5. Turn the control knob or switch on the gas valve to the
OFF position. (See Fig. 18 or 19.)
6. Replace the control access door. (See Fig. 13.)
7. If the furnace is being shut down because of a mal-
function, call your dealer as soon as possible.

Performing routine maintenance
With the proper maintenance and care, your furnace will
operateeconomically and dependably.Basic maintenance,
which can easily be accomplished by someone who
follows the directions, is found on this and the following
pages. However, before beginning maintenance, follow
these safety precautions:
Filtering out trouble
Adirtyfilterwillcauseexcessivestress on the furnace and
can cause it to overheat and automatically shut down.The
furnace filter should be checked every 3 or 4 weeks and
cleaned if necessary.
If your furnace filter needs replacing, be sure to use the
same size and type of filter that was originally supplied.
UsetheFurnaceFilterTableonthe nextpageandcompare
your furnace size with the proper filter size.
The air filter is normally located in the blower compart-
ment. If the filters have been installed in another location,
contactyour dealer for instructions.To inspect, clean,and/
or replace the air filter(s), follow these steps:

WARNING
Turn off electrical power supply to your furnace
before removing the access doors to perform ser-
vice or maintenance. A failure to follow this warn-
ing could result in personal injury or death.
CAUTION
Although special care has been taken to minimize
sharp edges, be extremely careful when handling
parts or reaching into the furnace.
CAUTION
Never operate your furnace without a filter in
place. Doing so may damage the furnace blower
motor. An accumulation of dust and lint on inter-
nal parts of your furnace can cause a loss of effi-
ciency.

Combustion area and vent system
Inspect the combustion area and vent system before each
heating season.An accumulation of dirt, soot, or rust can
mean a loss of efficiency and improper performance.
Buildups on the main burners can cause faulty firing. This
“delayed ignition” is characterized by an alarmingly loud
sound. If your furnace makes a loud noise when the main
burners are ignited, shut down the furnace—call your ser-
vicing dealer.
Use your flashlight and follow these steps for inspecting
the combustion area and vent system of your furnace:
1. Turn off the gas and electrical supplies to the furnace
and remove the access doors. (See Fig. 6, 7, and 8.)
2. Carefully inspect the gas burner (see Fig. 23) for dirt,
rust, or scale. Then inspect the inducer, vent connec-
tion area, and the vent pipe for rust.
NOTE:
If dirt, rust, soot, orscale accumulations are found,
call your servicing dealer. DO NOT OPERATE THE
FURNACE.
3. Inspect the vent pipe for a sag, holes, or a disconnec-
tion. A horizontal vent pipe must slope upward away
from the furnace. If rusty joints or seams, or signs of
water leakages are found call your dealer for service.

4. Replace the access doors and restore gas and electrical
supplies to the furnace. Be sure bottom door flange is
insideofthefurnacecasing.(SeeFig.13,14,15,and22.)

If not (or if you suspect some other malfunction), call
your servicing dealer.
Before you request a“service call”
Before you call for service,check for several
easily solved problems:
• Check for sufficient airflow surrounding the furnace.
Check the air filter for dirt. Check for blocked return-air
or supply-air grilles. Be sure they are open and unob-
structed. If this isn't the cause, call your servicing dealer.
WARNING
If holes caused by deterioration are found—or
holes in the vent pipe—or if the vent pipe is ob-
structed or is not connected—toxic fumes can es-
cape into your home. DO NOT OPERATE YOUR
FURNACE. Call your dealer for service. A failure to
follow this warning could result in personal injury
or death.

If your furnace isn’t operating at all, check the following
list for easily solved problems:
• Is your thermostat set above room temperature? Is the
HEAT mode selected?
• Is the electrical power supply switch ON? Is the blower
access door firmly in place?Are any fuses blown? (There
is a 3-amp automotive type fuse on the furnace control
board.) Has a circuit breaker tripped?
• Isthemanualshutoffvalveinthegassupplypipeleading
tothefurnaceopen?Doesthe leverpointinthesame direc-
tion that the pipe runs (open)? Or is it at right angles
(closed)?
NOTE:
Before proceeding with the next checks, turn OFF
the electrical power supply to the furnace. Remove the
access doors.
• Is the control knob or switch on the gas valve turned to
the ON position? If this or the preceding check shows an
interruption in the gas supply, make sure the gas has not
been shut off for safety reasons. If nothing else seems to
be wrong, follow the startup procedures found on pages 3,
4, and 5 of this user’s manual.
• If for some reason the vent is blocked, the draft safe-
guard switch or blocked vent shutoff switch (when used)
will shut off the furnace. Reset the switch by pushing the
button located on the switch. (See page 2 for switch
location.)
If the switch trips a second time, turn off the furnace and
call for service.
• If your furnace still fails to operate, call your servicing
dealerfor troubleshooting and repairs.Tellyour dealer the
model and serial numbers for your furnace. (You should
havethemrecordedonpage8ofthisbooklet.)Byknowing
exactly which furnace you have, the dealer may be able to
offer suggestions over the phone, or save valuable time
through knowledgeable preparation for the service call.
Regular dealer maintenance
In addition to the type of routine maintenance you might
be willing to do, your furnace should be inspected regu-
larly by a properly trained service technician. An annual
inspection (or biennial inspection, at least) should include
the following:
1. Inspection of all combustion product passages—
including the burners, heat exchanger, inducer, and
vent pipe.
2. Inspection of all combustion air and ventilation air
passages and openings.
3. Close check of all gas pipes leading to (and inside of)
your furnace for leaks.
4. Inspection, cleaning, and lubrication (when required)
of the blower motor and wheel.
NOTE:
Refer to the unit Service Procedures for blower
motor oiling information. When required, the motor
should be oiled by a qualified service technician. (Wrong
oil type or excessive oil is detrimental to the motor.)
5. Routine inspection and cleaning/replacement of the
air filter.
6. Inspection of all supply- and return-air ducts for
obstructions, air leaks, and insulation. Any problems
found should be resolved at this time.
7. Inspection of furnace installation for proper support
and any obvious deterioration of the furnace. The sup-
port must be sound and without sags, gaps, cracks,
etc., around the furnace base so as to provide an air
seal between the support and furnace.
8. A check for loose connections attaching individual
components. Inspection of all electrical wiring and
their connections.
9. Operational check of the furnace itself to determine
working condition. Repair or adjustment should be
made at this time.
Ask your servicing dealer for further details about an eco-
nomical service contract that covers seasonal inspections.
