DESCRIPTION

These high efficiency, compact units employ induced com-
bustion, reliable hot surface ignition and high heat transfer
aluminized tubular heat exchangers. The units are factory
shipped for installation  in upflow or horizontal applications.

These furnaces are designed for residential installation in a
basement, closet, alcove, attic, recreation room or garage
and are also ideal for commercial applications. All units are
factory assembled, wired and tested to assure safe depend-
able and economical installation and operation.

These units are Category I listed and may be common vented
with another gas appliance as allowed by the National Fuel
Gas Code.

WARRANTY

20-year limited warranty on the heat exchanger.

10-year heat exchanger warranty on commercial applica-
tions.

5-year limited parts warranty.
