This 55,000 BTU counterflow direct-vent furnace delivers powerful, consistent warmth for larger rooms, giving you the performance of a propane gas heater with efficient floor-to-ceiling circulation. The counterflow blower draws warm air from the ceiling and moves it down toward the floor, helping equalize temperatures throughout the space for more balanced comfort. Designed for installation on an exterior wall, the heater discharges all combustion by-products outdoors through a horizontal vent, creating a clean and reliable gas wall heater solution for homes, garages, workshops, or basements. Because the unit requires no electricity, it continues operating during outages and serves as a dependable indoor heater during harsh winter conditions. With a 77% AFUE rating, the furnace supports efficient operation, while the included blower and optional outlet kits expand your ability to direct heat to multiple rooms. A soft-white, powder-coated finish blends easily with most interiors and keeps the heater looking clean through everyday use. Safety features such as intermittent pilot ignition, automatic controls, and a resettable vent-limit switch support confident operation, making this system a practical choice for high-capacity gas heaters for indoor use that deliver long-term comfort and performance.
