These furnaces are designed for residential installation in a basement,
closet, alcove, attic, recreation room, or garage. All units are factory
assembled, wired, and tested to ensure safe, dependable, and eco-
nomical installation and operation.
These units are Category IV listed and may not be common vented with
another gas appliance as allowed by the National Fuel Gas Code.
