Trane A801X080BM4SC 80 Percent Afue Gas Furnace 80000 Btu Multipositional Upflow Downflow Horizontal

Product Description

The Trane A801X080BM4SC is a single-stage, multipositional gas furnace rated at 80,000 BTU input capacity and 80 percent AFUE efficiency. It is designed for residential forced-air heating systems and can be installed in upflow, downflow, or horizontal left/right orientations, making it adaptable to a wide range of installation layouts. The furnace operates on 120/1/60 voltage with 24-volt low-voltage control and features an integrated furnace control board with digital display, setup and diagnostic functions, and storage of the last six fault codes. All electrical connections use Molex connectors. A four-speed direct-drive blower motor handles airflow for both heating and cooling modes. Licensed HVAC technicians perform installation and service.

The A801X080BM4SC is suited for residential applications where a single-stage, non-condensing gas furnace is specified. Its multipositional cabinet design accommodates upflow, downflow, and horizontal installations, giving installers flexibility in equipment room, closet, attic, and crawlspace placements. The open vestibule design provides a full 34-inch high access area for ease of service. The cabinet width of 17.5 inches is compatible with industry-standard evaporator coils and accessories, making it a practical choice for split-system configurations where a matched or compatible cooling coil is installed above or below the unit.
