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.
