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