Goodman ad9t800603bx 80 Afue Two Stage Gas Furnace

Product Description

The GOODMAN ad9t800603bx is an 80 AFUE, two-stage, downflow and horizontal gas furnace rated at 60,000 BTU/h high-fire input capacity. It uses a multi-speed ECM blower motor and a Low NOx burner, making it a fit for residential and light-commercial applications where emissions compliance is required. The two-stage gas valve allows the unit to run at reduced fire (42,000 BTU/h input) during mild demand and ramp to full capacity when needed. Licensed HVAC technicians handle installation, as this unit involves gas piping, electrical connections, and venting work under local mechanical codes.

The ad9t800603bx is configured for downflow and horizontal installation, matching applications where supply air flows downward through the furnace or is discharged horizontally. At 17.5 inches wide, it fits a standard platform or alcove sized for that cabinet width. The unit is rated for 3-ton nominal cooling capacity (36,000 BTU/h), so it pairs with a matching 3-ton cooling coil in a split system. High-fire airflow reaches approximately 1,207 CFM to support full system air delivery. Single-phase, 115-volt, 60 Hz power feeds the unit with a minimum circuit ampacity of 8.7 amps and maximum overcurrent protection of 15 amps.

Compatibility

Designed as a downflow and horizontal installation gas furnace for residential and light-commercial split systems requiring a 3-ton nominal cooling match and a 17.5-inch cabinet width. Compatible system pairings and coil models should be confirmed against current Goodman and Amana product documentation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the National Fuel Gas Code (NFPA 54), local mechanical codes, and the manufacturer installation instructions. Shut off gas supply and disconnect electrical power before servicing or connecting the unit. Proper venting must be installed per the appliance category and local jurisdiction requirements. Verify temperature rise falls within the rated range of 30 to 60 degrees F at high fire before completing startup.
