WELCOME TO A NEW
GENERATION OF
COMFORT
Congratulations! In light of rising
energy costs, the 345MAV Multipoise
Condensing Gas Furnace is among the
soundest investments today’s home-
owner can make.
Your new furnace is truly a triumph
of technology in home heating. A
revolutionary design employs 2 heat
exchangers to “squeeze” out the maxi-
mum amount of heat from the fuel con-
sumed. In fact, your new furnace is so
efficient, 90%* 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.
The furnace is among the most energy-
efficient furnaces you can buy today. It
is also among the safest and most
dependable. We are proud of the tech-
nological 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 Department of
Energy test procedures.
