Williams Comfort Products CDV156C Direct Vent Wall Furnace

Product Description

The WILLIAMS COMFORT PRODUCTS CDV156C is a direct vent wall furnace rated at 15000 BTU/h input and 10000 BTU/h output, delivering a 67% AFUE efficiency rating on liquid propane fuel. Built with a steel cabinet finished in eggshell white, this unit mounts directly to an exterior wall and draws combustion air from outside while exhausting flue gases through a single-side termination. A 9-inch supply opening distributes heated air into the conditioned space. Licensed HVAC technicians install this unit in residential applications where space heating is needed without a central duct system.

The CDV156C is suited for residential supplemental or primary space heating in rooms that lack access to a central forced-air system. Its direct vent design makes it appropriate for tight or well-sealed spaces where indoor air quality and combustion safety are concerns. The single-side vent configuration simplifies wall penetration in standard wood-frame or masonry construction. The unit ships ready for liquid propane service and is domestically manufactured.

Shut off the propane supply and verify zero pressure at the appliance before beginning any connection work.
