These high efficiency, compact units employ induced combustion, reli- able hot surface ignition and high heat transfer aluminized tubular heat exchangers. The units are factory shipped for installation in upflow or horizontal applications and may be converted for downflow applica- tions.

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 dependable and economical installation and oper- ation.

These units are Category IV listed and may not be common vented with another gas appliance as allowed by the National Fuel Gas Code.
