WELCOME TO TODAY'S GENERATION
OF COMFORT
Congratulations! In light of rising energy costs, a 90+% AFUE
Condensing Gas Furnace from Carrier Corporation is among the
soundest investments 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
"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.
This furnace is among the safest, most dependable,
energy-efficient furnaces you can buy today. We are proud of the
technological advances incorporated into the design of this furnace.
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.
