WELCOME TO A NEW
GENERATION OF COMFORT
Congratulations! In light of rising energy costs, the Infinity ICS
Gas-Fired, Modulating Condensing Furnace is among the wisest
investment today's homeowner can make.
Your new furnace is truly a triumph of technology in home
heating. A revolutionary design employs two heat exchangers to
maximize the amount of heat from the fuel consumed. In fact,
your new furnace is so efficient, up to 95%* of the heat generated
during combustion is captured and delivered inside your home.
That is more than a 33%* increase in heating efficiency over
conventional furnaces.
These are among the most energy-efficient furnaces you can buy
today. They also are among the safest and most dependable. We
are proud of the technological advances incorporated into the
design of these furnaces. With only minimal care, your new
furnace 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 operating at peak efficiency
year after year.
*The output capacity and any representations of efficiency for this furnace
are based on standard U.S. Department of Energy test procedures.

SAFETY CONSIDERATIONS
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 personal iniury.
Understand the signal words: DANGER, WARNING, and
CAUTION. DANGER identifies the most serious hazards which
will result in severe personal iniury or death. WARNING signifies
hazards which could result in personal iniury or death.
CAUTION is used to identify unsafe practices which may result
in minor personal iniury or product and property damage. NOTE
is used to highlight suggestions which will result in enhanced
installation, reliability or operation.
To minimize the possibility of serious personal iniury, fire,
furnace damage, or improper operation; carefully follow these
safety rules:
• Your gas furnace uses air from outside the home for
combustion and vents flue gas to the outdoors. It is not
to be installed using indoor air for combustion. The
vent pipe nmst terminate outside the structure and must
not be obstructed in any way. The air-intake pipe must
terminate outside the structure or in a well ventilated
area that is isolated from the living space and the garage
(e.g. well ventilated attic or crawlspace). Do not block
or obstruct air openings on furnace or spaces around
furnace.
A92182
Fig. 4 - Combustible Materials
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 furnace area when the furnace is installed
or when insulation is added. Some materials may be
combustible.
This furnace contains SAFETY DEVICES which must
be MANUALLY RESET. If the furnace is left
unattended for an extended period of time, have it
checked periodically for proper operation. This
precaution will prevent problems associated with no
heat, such as frozen water pipes, etc. See "Before You
Request a Service Call" section in this manual.

Keep the area around your furnace clear and free of
combustible materials, gasoline, and other flammable
liquids and vapors.
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal
iniury/death or property damage.
Do not keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.
FIRE AND UNIT OPERATION HAZARD
Failure to follow this warning could result in personal
iniury/death or property damage.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct the
openings on the furnace, air openings to the area in which the
furnace is installed, and the space around the furnace.

BEFORE STARTING YOUR
FURNACE
Examine the furnace installation monthly to determine that:
1. All flue gas carrying areas external to the furnace (i.e.
chinmey, vent connector) are clear and free of obstructions.
2. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
3. The return-air duct connection(s) is physically sound, is
sealed to the furnace casing, and terminates outside the space
containing the furnace.
4. The physical support ofthe furnace is sound without sagging
cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.

6. The burner flames are in good adjustment. (See Fig. 5.)
STARTING AND SHUTTING DOWN
YOUR FURNACE
FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Should the gas supply fail to shut off or if overheating
occurs, turn off the manual gas valve to the furnace
BEFORE turning off the electrical supply. (See Fig. 8.)
• CHECK AIR FILTER: Before attempting to start
your furnace, be sure the furnace filter is clean and in
place. See "Performing Routine Maintenance" section
in this manual. Then proceed as follows:
Steps For Starting Your Furnace
1. Set your room thermostat to the lowest temperature setting.
(See Fig. 7.)
2. Close the external manual gas valve. (See Fig. 8.)
A92330
Instead of a continuously burning pilot flame which wastes
valuable energy, your furnace uses an automatic, hot surface
ignition system to light the burners each time the thermostat starts
your furnace. Follow these important safeguards:
• Never attempt to manually light the burners with a
match or other source of flame.
A92319
Fig. 6 - Do Not Light Burner with Match
• Read and follow the operating instructions on inside of
main furnace door, especially the item that reads as
follows:
Wait 5 minutes to clear out any gas. Then smell for gas,
including near the floor. If you smell gas, STOP!
Follow "B" in the safety information above on this
furnace 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 inside of
main furnace door, or in the "Shutting Down Your
Furnace" section and call your dealer as soon as
possible.

3. Turn OFF electrical supply to the furnace. (See Fig. 9.)
4. Remove main furnace door. (See Fig. 10.)
5. The gas valve will have a control switch to turn off and on.
Turn the control switch on the gas control to the OFF
position and wait 5 minutes. (See Fig. 11.) Then smell for
gas, including near the floor. If you smell gas, STOP! Follow
"B" on furnace label. If you don't smell gas, go to next step.
6. After waiting 5 minutes, turn the control switch on the gas
control to the ON position. (See Fig. 12.)
