Product Description

The Trane A801X120DM5SD is a single-stage, non-condensing natural gas furnace rated at 120,000 BTU/h input with 80% AFUE efficiency. Part of the RunTru by Trane RT Series, it features a constant torque ECM blower motor and a 4-way multi-positional cabinet that installs in upflow, downflow, horizontal left, or horizontal right configurations. Nominal airflow capacity is 2,000 CFM with a 9-tap control transformer motor. The 24-volt control circuit is standard. Licensed HVAC technicians install this unit in residential forced-air heating systems where straightforward single-stage operation and installation flexibility are the primary requirements.

The multi-positional design accommodates a wide range of mechanical room layouts, attic installs, crawlspace horizontals, and basement upflow configurations. It operates on natural gas and is certified for both natural and LP gas service. Select models with a T in the 12th digit of the model number meet California low-NOx emissions requirements at less than 40 ng/J. The cabinet measures 34 inches high by 24.5 inches wide by 28.75 inches deep, fitting standard residential air handler spaces.
