Transform your home into a cozy sanctuary with the 17,000 BTU Direct Vent Propane Wall Heater. This efficient heating solution will banish the chill, providing warmth and comfort for you and your loved ones. Say goodbye to cold corners and hello to a snug, inviting atmosphere. This industry-leading wall furnace keeps your living or workspace warm with a direct vent wall heater that disperses pure, gentle heat, in continuous circulation. The space-saving direct vent furnace design mounts to an exterior wall. When installing wall thickness cannot be less than 4.5 inches and cannot exceed 10.00 inches. The gas flame with matchless Piezo lighting 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. Windows and doors can stay closed because no room air is used for combustion. For additional safety, the pilot has a built-in pressure regulator that completely stops the flow of gas in the event the pilot is extinguished. This wall furnace is designed to heat up to 570 square feet and has a 17,000 BTU input. This model is only for propane gas installations and is incompatible with natural gas. Add some coziness to your home with the Direct Vent Propane Wall Heater.
