Product Overview
This direct-vent counterflow wall furnace by Williams Furnace Company is a highly efficient indoor heating unit that, operating at 40,000 BTU, works to safely distribute heat throughout any indoor space at minimal cost. It has a standing pilot and includes a thermostat and blower. It is an ideal heating solution for homes, apartments, offices, and schools. Conveniently compact - just 11 3/4 inches deep and requiring less than one square foot of floor space, it can be flush mounted or recessed into an exterior wall. With an added side outlet kit, it can even be used to heat a second room.
This unit is a direct-vent counterflow furnace, which means it utilizes outdoor air to ensure an even floor-to-ceiling heat. This heater is a great option for garages, workshops, and even bedrooms. This Direct-vent furnace must be installed on an exterior (outdoor) wall and vent horizontally out the rear of the unit. This allows the unit to draw in fresh outdoor air as well as eliminate exhaust. This also allows for doors and windows to remain closed because no interior air is used for combustion.
Counterflow furnaces operate by way of an internal blower system that, coupled with an efficient heavy-duty motor, quietly warms the air drawn from outside and and disperses heat through the bottom of the unit. Because warm air naturally rises, the heat delivered at the floor level becomes evenly disbursed throughout the entire room, for consistently comfortable interior temperatures. All wiring and controls are easily accessible from the front of the unit.
