outdoors into the combustion chamber and combustion gases are
discharged directly to the outdoors through tubes mounted to the
rear of the furnace.
The furnace heat exchanger is built of heavy gauge steel treated
for corrosion resistance. The fan at the top, forces air down along
the front, back and sides of the heat exchanger where it is
discharged into the room. The furnace cabinet is also constructed
of heavy gauge steel and has a powder-coat paint finish.
The furnace controls are located behind an access door on the
lower front of the furnace. All models are equipped with American
