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
