Product Description

The Trane A801X100CM5SA is a single-stage, multi-position induced-draft gas furnace rated at 100,000 BTU/h input capacity and 80% AFUE. It is designed for residential heating applications where dependable performance and installation flexibility are priorities. The multi-position design supports upflow, horizontal-left, horizontal-right, and downflow orientations, allowing installation in a range of mechanical room and closet configurations. Licensed HVAC technicians install this furnace as part of a split-system or packaged heating setup. The 80% AFUE rating means 80 cents of every fuel dollar is converted to usable heat.

This furnace is suited for medium to large residential buildings requiring a high-input heating source. Its single-stage gas valve delivers consistent heat output throughout each call for heat. The multi-positional cabinet makes it adaptable for basement, attic, closet, or crawlspace installations where duct routing and equipment orientation vary. A 24-volt control circuit interfaces with standard residential thermostat wiring and compatible air handler accessories.
