These high efficiency, compact units employ induced combustion, reli-
able hot surface ignition, and high heat transfer tubular heat exchang-
ers. 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 ensure safe, dependable, and economical installation and
operation.
These units are Category IV listed and can not be common vented with
another gas appliance as allowed by the National Fuel Gas Code.
