Trane A801X080BM4SD Single Stage Gas Furnace 80000 Btu 80% Afue Multi-positional

Product Description

The Trane A801X080BM4SD is a single-stage, induced-draft gas furnace rated at 80,000 BTU input capacity and 80% AFUE efficiency. Part of the RunTru by Trane RT Series, this unit is built for residential forced-air heating systems where straightforward, reliable performance is the priority. The cabinet measures 17.5 inches wide and 28.75 inches deep, making it well-suited for standard residential installations. It operates on a 120/1/60 electrical supply with 24-volt low-voltage control and uses a high-efficiency motor with multi-speed capability. A licensed HVAC technician is the appropriate installer for this equipment.

The A801X080BM4SD is designed for multi-positional installation, meaning it can be configured for upflow, downflow, horizontal left, or horizontal right airflow depending on the application. This flexibility makes it a practical choice for residential new-construction installs and equipment replacements in a variety of mechanical room layouts, including basement, closet, attic, and crawlspace installations. The 4-way installation capability reduces the need for multiple SKUs across different job types.
