The DVAG30N Direct Vent Wall Heater from Ashley Hearth Products makes the perfect solution for zoned heating. The space saving direct vent furnace design mounts to an exterior wall and the adjustable vent assembly adjusts to fit walls from 4-1/2 in. to 10 in. thick. For clean, comfortable heat when and where you want it, the gas flame is completely sealed inside, away from all contact with room air. Air necessary for combustion is drawn into the chamber from outside through the vent and combustion products are vented directly to the outside. Only clean, gentle heat, in continuous circulation is delivered into the room. Windows and doors stay closed because no room air is used for combustion. The DVAG30N direct vent natural gas wall heater is designed to heat up to 825 sq. ft. and has a 25,000 BTU input.
