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.
A05097
Fig. 1 - Infinity ICS Variable Capacity Furnace
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.

PERFORMANCE
HAZARD
Failure to follow this caution may result in product damage.
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.
A05099
Fig. 19 - Remove
Furnace
Door
A dirty air filter will cause a loss of airflow in your duct system.
When excessive loss of airflow occurs, the furnace may cycle on
its safety controls. If this condition is left unattended, the furnace
will eventually lock out. It is recommended that the furnace air
filter be checked every 3 or 4 weeks and cleaned if necessary.
If installed with factory-specified disposable media filter, check
or replace filter before each heating and cooling season. Replace
disposable media filter at least once a year.
The air filter is normally located in the blower compartment or
in the factory-supplied filter cabinet attached to the side or
bottom of the furnace casing. If air filter has been installed in
another location, contact your dealer for instructions. To inspect,
clean, and/or replace the air filter(s), follow these steps:
1. Turn off electrical supply to furnace. (See Fig. 17.)

2. Remove door/access panel.
