The GMS8/GDS8 multi-position gas furnaces features a patented aluminized steel tubular heat exchanger and high-efficiency hot surface ignition system. These furnaces are run-tested for heating or combination heating/cooling applications. With a heavy-gauge, reinforced, wrap-around insulated steel cabinet and durable baked enamel finish, these units can be installed in a utility room, closet, alcove, basement or attic. (Not intended for use in mobile homes.)
