WELCOME TO A NEW GENERATION OF
COMFORT
Congratulations! In light of rising energy costs, this deluxe gasfired, condensing furnace is one of the soundest investments to
day’s homeowner can make.
Your new furnace is truly a triumph of technology in home heat
ing. The design employs two heat exchangers to ‘"squeeze” out
the maximum amount of heat from the fuel consumed. In fact,
your new furnace is so efficient, over 90%* of the heat generated
during combustion is captured and delivered inside your home.
That’s more than a 33%* increase in heating efficiency over con
ventional furnaces.
This unit is not only one of the most energy-efficient furnaces
you can buy today, it is also one of the safest and most depend
able. We are proud of the technological advances incorporated
into this furnace design. With only minimal care, your new fur
nace will deliver many years of money-saving home comfort and
enjoyment. Spend just a few minutes with this manual to learn
the operation of your new furnace and the small amount of
maintenance it takes to help keep it opera ting at peak efficiency
year after year.
'The output capacity and any representations of efficiency for this furnace are based on stan
dard Department ofEner^ test pmeeduresi.

IMPORTANT FACTS
Your gas furnace uses air from outside the home for combus
tion and venting. It is not to be installed using in-house air.
Therefore, both pipes must terminate outside the structure.
These pipes must not be obstructed in any way.
NOTE: The qualified installer or agency must use only factory-
authorized replacement parts, kits, and accessories when modi
fying this product.
If the furnace is left unattended for an extended period of time,
have it checked periodically for proper operation. This precau
tion will prevent problems associated with NO HEAT, such as
frozen water pipes, etc., see “Before You Request a Service Call”
in this manual.
SAFETY CONSIDERATIONS
Installation and servicing of beating equipment can be hazard
ous due to gas and electrical components. Only trained and
qualified personnel should install, repair, or service heating
equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning and replacing air filters. All other operations
must be performed by trained service personnel. Observe safety
precautions in this manual, on tags, and labels attached to the
furnace and other safety precautions that may apply.
Recognize safety information: This is the safety-alert symbol
A. When you see this symbol on the furnace and in instruc
tions or manuals, be alert to the potential for personal injury.
Understand the signal word—DANGER, WARNING, or CAU
TION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies hazards
that could result in personal injury or death. CAUTION is used
to identify unsafe practices, which would result in minor per
sonal injury or product and property damage.
To minimize the possibility of serious personal injury, fire,
damage to your furnace, or improper operation, carefully follow
these safety rules:
• Keep the area around your furnace free of combustible mate
rials, gasoline, and other flammable liquids and vapors.
• Do not cover the furnace, store trash or debris near it, or in
any way block the flow of fresh air to the unit.
• A furnace installed in an attic or other insulated space must
be kept free and clear of insulating material. Examine the fur
nace area when installing the furnace or adding more insula
tion. Some materials may be combustible.
NOTE: Do not use this furnace if any part has been under wa
ter. 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.
STARTING YOUR FURNACE
Instead of a continuously burning pilot flame which wastes val
uable energy, your furnace uses an automatic hot surface igni
tion system to light the burners each time the thennosLat turns
your furnace on. Follow these important safeguards:
• Never attempt to light the burners manually with a match or
other source of flame.
AS6023
• Read and follow the operating instructions on the furnace.
4
• If a suspected malfunction occurs with your gas control sys
tem, such as the burners not lighting 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.
Page 7
WARNING
If overheating occurs, or the gas valve fails to shut off the
gas supply, turn OFF the manual gas valve (see Fig. 7) to
the furnace BEFORE turning OFF the electrical supply.
Failure to follow this warning could result in a fire or explo
sion, and personal injury or death.
• CHECK AIR FILTER: Before attempting to start your furnace,
be sure the furnace filter is clean and in place. (See the mainte
nance section of this manual.) Then proceed as follows:
STEPS FOR STARTING YOUR FURNACE
1. Set your room thermostat to the lowest temperature set
ting. (See Fig. 6.)
2. Close the external manual gas valve. (See Fig. 7.)
3. Turn OFF the electrical supply to the furnace. (See Fig. 8.)
8. Set the room thermostat to a temperature slightly above
room temperature. This will automatically signal the fur
nace to start. The inducer motor will start, and the hot sur
face ignitor will energize. When hot, the ignitor will have
an orange glow.
and wait 5 minutes. (See Fig. 9.)
9
A911S2
5. After waiting 5 minutes, turn the control knob on the gas
valve to the ON po.sition. (See Fig. 9.)
6. TUrn ON the electrical supply to the furnace. (See Fig. 10.)
7. Open the external manual gas valve. (See Fig. 11.)
11
A86035
9. After 30 to 58 seconds, the gas valve permits gas to flow to
the main burners where it is ignited. Hot flames begin to
warm the furnace’s heat exchanger. After a time delay of
approximately 60 seconds, the furnace blower is switched
on.
NOTE: If the main burners fail to ignite, the furnace control
system will go through three more ignition cycle.s. 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.
10. Set your thermostat to the temperature that satisfies your
comfort requirements. SUGGESTION; Setting the ther
mostat back a few degi'ees—and compensating for the dif
ference 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
selected on the thermostat, the furnace will be switched on
automatically. When the room temperature reaches the
degree selected on the thermostat, the furnace will be au
tomatically switched off.
Page 8
Some thermostats have a “fan” switch with two selections:
AUTO or ON. When set onAUTO, the hirnace blower cy
cles on and off, controlled by the thermostat. In the ON
position, the furnace blower runs continuously except for a
60 second 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 procedures must
be followed:
1. Set your room thermostat to the lowest temperature set
ting. (See Fig. 12.)
2. Close the external manual gas valve. (See Fig. 7.)
3. Thm OFF the electrical power to your furnace. (See Fig.
4. Tbrn the control knob on the gas valve to the OFF position.
(See Fig. 14.)
A WARNING
Tbrn OFF electrical power supply to your furnace before re-
movingtheaccess doors to service orperfoim maintenance.
Failure to follow this warning could result in personal in
jury or death.
A CAUTION
Although special care has been taken to minimize sharp
edges, be extremely careful when handling parts or reach
ing into the furnace.
FILTERING OUT TROUBLE
A dirty filter will cause excessive stress on the furnace blower
motor and can cause it to overheat and automatically shut
down. The furnace filter should be checked every 3 or 4 weeks
and cleaned if necessaiy.
A 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 internal parts of your furnace can cause
a loss of efficiency.
The air filter is normally located in the blower compartment be
fore the blower (See Fig. 16.) If thefilter(s) has been installed in
another location, contact your dealer for instructions. To in
spect, clean and/or replace the air filter(s), follow these steps:
If your furnace filter needs to be replaced, be sure to use the
same size and type of filter that was originally supplied. Use the
furnace filter table and compare your furnace size with the
proper filter size.
14
А9П82
5. If the furnace is being shut down because of a malfunction,
call your dealer as soon as possible.
A CAUTION
Furnace is not to be installed, operated, and then turned off
and left turned off in an unoccupied structure during win
ter. (See winterizing procedures in maintenance section).
PERFORMING ROUTINE MAINTENANCE
With proper maintenance and care, your furnace will operate
economically and dependably. Instructions for basic mainte
nance, which can easily be followed, are found on this and the
following pages. However, before beginning maintenance, fol

3. Bend the formed wire filter retainer to clear the furnace
flange at one side.
4. Pivot the filter retainer toward the blower. (See Fig. 16.)
5. Remove the filter from the furnace.
6. Inspect the filter. If torn, replace it.
7. Wash the filter (if dirty) in a sink, bathtub, or outside with
a garden hose. Always use cold tap water. A mild liquid de
tergent may be used if necessary. Spray water through the
filter in the opposite direction of airflow through the cross
mesh binding side. Allow filter to dry.
8. Reinstall the clean filter with the cross-mesh binding side
facing the furnace blower.
9. Replace blower door, reinstall 4 screws (see Fig. 17) and
turn OM electrical power to your furnace.
Inspect the gas burners for dirt, rust, or scale. (See Fig. 18.)
Then inspect the vent outlet area and vent pipe.
A CAUTION
If dirt, rust, soot, or scale accumulations are found, call
your dealer.
Do not operate your furnace.
3. Inspect the vent pipe for sag, holes, cracks, or dis
connection. Any horizontal vent pipe must slope upward,
away from the furnace; look for signs of water leakage.
17
A91185
COMBUSTION AREA AND VENT SYSTEM
Visually inspect the combustion area and vent system before
each heating season. Make sure that all PVC pipes leading into
the combustion area and vent are free from any cracks and sags.
Also check the combustion air intake and vent pipes on the out
side of your home for blockage.
When dirt, soot or rust is allowed to build up, your furnace can
suffer a loss of efficiency and perform improperly. Accumula
tions on the main burners can result in their firing out of nor
mal sequence. This delayed ignition will create an alarmingly
loud sound.
A CAUTlOÑ
If your furnace makes an especially loud noise when the
main burners light, shut down your furnace and call your
dealer.
Tb inspect the combustion area and vent system, you will need
a flashlight. Refer to Fig. 2, and proceed as follows:
1. Tarn OFF the electrical supply to your furnace.
2. Remove burner enclosure front.
A DANGER
If holes are found in the vent pipe, or if it has become dis
connected, toxic fumes can escape into your home. DO
NOT OPERATE YOUR FURNACE. Call your dealer for
service.
4. Reinstall the burner enclosure front.
5. If your furnace is free of the above conditions, restore elec
trical power to your furnace. (See Fig. 10.)
6. Start your furnace and observe its operation. Watch the
burner flames to see if they are bright blue. (See Pig. 19) If
you observe a suspected malfunction, or the burner ñames
are not bright blue, call your dealer.
HEADING SOUTH FOR THE WINTER?
DON’T FORGET YOUR FURNACE!
Since the furnace uses a condensing heat exchanger, some wa
ter will accumulate in the unit as a result of the heat transfer
process. Therefore, once it has been operated, it cannot be
turned off and left off for an extended period of time when tem
peratures will reach 32°F or lower, unless winterized. Follow
these procedures to winterize your furnace:
1. Mix a solution of equal amounts of ethylene glycol (Pres
tone II antifreeze coolant or equivalent) and water.
2. Tbm OFF electrical supply to furnace. (See Fig. 8.)
3. Disconnect drain tube from bottom of inducer vent outlet.
(See Pig. 20.)
4. Insert funnel in drain tube and pour antifreeze/water solu
tion into furnace until it is visible at point where conden
sate enters open drain. (See Fig. 21.)
5. Reconnect drain tube to vent outlet.

A CHECKUP CHECKLIST
Your furnace represents an important investment in your fam
ily’s comfort and your home’s value. To keep it in tip-top shape
and as a preventative to future problems, have a trained service
specialist give your furnace a professional check-up annually.
The following checklist can be used as a guideline to proper
service:
• Inspect all flue gas passages, burners, heat exchangers, cou
pling box(es), and inducer assembly.
• Inspect all combustion and ventilation air passages and
openings, including combustion air and vent pipe terminations
outside the structure.
• Check gas pipe.s leading to and inside of your furnace for
leaks.
• Inspect, clean, and lubricate the blower motor and wheel as
required.
NOTE: If oil ports are provided, refer to the unit Service and
Maintenance Instructions for blower motor oiling information.
The motor must be oiled by a qualified service technician.
• Inspect and change or clean air fiiter(s) if necessary.
• Inspect all supply- and return-air ducts for obstructions, air
leaks, and insulation. Remedy any problem when necessary.
• Inspect electrical wiring, connections, and component.^ for
loose connections.
• Perform an operational checkout to determine whether your
furnace is working properly and if it requires adjustments.
• Inspect all condensate tubes and connections, condensate
trap assembly, and drain for leaks. The condensate removal
system should be cleaned annually by a qualified service
agency; refer to the Service and Maintenance Instructions for
further information.
• Examine the physical support of the furnace; the support
should be sound with no cracks, sagging, gaps, etc. around the
base.
• Check the furnace for any obvious signs of deterioration.
• Your servicing dealer offers an economical service agreement
that covers seasonal inspections; ask for details.
BEFORE YOU REQUEST A
SERVICE CALL
If your furnace is not operating or not performing properly, you
may save the expense of a service call by checking a few things
yourself before calling for service.
FOR INSUFFICIENT AIRFLOW:
• Check for dirty air filter(s).
• Check for blocked return-air or supply-air grilles throughout
your home; ensure they are open and unobstructed.
If problem still exists, call your dealer for service.
WHEN FURNACE FAILS TO OPERATE:
Follow this checklist step by step, advancing to the next one
only if furnace fails to start.
• Cheek thermostat for proper temperature (set above room
temperature).
• Is the thermostat switch on HEAT?
• Check fuses and circuit breakers. Is electrical supply on?
• Is the manual shut-off valve in gas supply pipe in open posi
tion? (Follow startup procedures if you open gas valve.)
NOTE: Tlirn OFF the electrical power supply before continuing
with checklist.
• Is the control knob on gas valve in ON position? (Follow
startup procedures If you must reset knob to ON.)
If your furnace still fails to operate, call your service
representative.
