Goodman ad9t801005cx Gas Furnace 100K Btu 80 Afue Two Stage

Product Description

The GOODMAN ad9t801005cx is a downflow and horizontal-configuration gas furnace rated at 80 AFUE, designed for residential and light-commercial forced-air heating systems. It delivers 100,000 BTU/h input at high fire and 80,000 BTU/h output, stepping down to 70,000 BTU/h input and 56,000 BTU/h output at low fire through its two-stage gas valve. The multi-speed ECM blower motor moves up to 2,221 CFM at high-fire heating mode, supporting up to 5-ton cooling configurations. The unit runs on 115 volts, single-phase, 60 Hz power and carries ANSI certification. Licensed HVAC technicians handle installation of this furnace in new-construction and replacement applications.

This furnace is configured for downflow and horizontal installation, making it suited for installations where supply air is directed downward or horizontally, such as closet, alcove, or crawl-space applications. The low-NOx burner design supports use in air-quality-regulated markets. With a 21-inch width, 33-3/8-inch height, and 28-inch depth, it fits within standard equipment clearances for residential and light-commercial builds. The two-stage gas valve allows the system to modulate between low-fire and high-fire operation, reducing short-cycling and improving comfort and efficiency across varying load conditions.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the International Fuel Gas Code (IFGC) and all applicable local codes. Shut off gas supply and disconnect electrical power before beginning any service or installation work. Verify that flue venting, gas line sizing, and electrical circuit protection match the unit requirements, including a minimum circuit ampacity of 15.32 amps and a maximum overcurrent protection of 20 amps. Do not exceed the published temperature rise range of 20 to 50 degrees F at high fire.
