is among
ICS
the wisest
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 tn help keep it operating
at peak efficiency
year after year.
