Trane A801X100CM5SC Gas Furnace 100000 Btu/h 80% Afue Single Stage Multi-position

Product Description

The Trane A801X100CM5SC is a single-stage, induced draft gas furnace rated at 100,000 BTU/h input and 80% AFUE. It is designed for multi-position installation, supporting upflow, downflow, horizontal left, and horizontal right configurations. The unit runs on a 120/1/60 power supply with 24-volt control and uses a high efficiency motor to move conditioned air through residential duct systems. An integrated furnace control board handles setup, status, and diagnostics with a digital display and stores the last six fault codes for quick troubleshooting. Licensed HVAC technicians install and service this unit.

This furnace is suited for residential forced-air heating applications where installation space, orientation requirements, or load demands vary by job. The 21-inch cabinet width follows industry standard dimensions, and the approximately 28.75-inch depth is compatible with industry standard evaporator coils and accessories. The open vestibule design stands 34 inches high, giving technicians clear access to components during installation and service. The cabinet meets ASHRAE 193 air leakage requirements at 1.4% or less, supporting system efficiency at the rated AFUE.
