General Electric NF97D090M4CR Modulating Gas Furnace 90000 Btu

Product Description

The General Electric NF97D090M4CR is a modulating downflow gas furnace rated at 90,000 BTU/h output with a 97% Annual Fuel Utilization Efficiency (AFUE) rating. Modulating burner operation adjusts heat output in small increments to match the actual load of the conditioned space, reducing short-cycling and improving comfort consistency. Compatible with R454B refrigerant systems in paired cooling applications, this furnace is suited for installation in a C-cabinet downflow configuration. Licensed HVAC technicians install this unit in residential or light-commercial forced-air heating systems where high-efficiency performance and modulating control are specified.

This furnace is designed for downflow duct configurations where supply air is discharged through the bottom of the cabinet. The 97% AFUE rating means nearly all fuel consumed is converted to usable heat, making it appropriate for projects requiring compliance with high-efficiency energy codes. At 3 tons of rated cooling airflow capacity, it supports matched split-system cooling with refrigerants including R454B. It is a fit for new construction and replacement installations in residential forced-air applications where modulating heat output is required.

Key Features

• 97% AFUE rating for high-efficiency fuel utilization in residential gas heating
• 90,000 BTU/h heating capacity suitable for mid-to-large residential spaces
• Modulating burner operation reduces on-off cycling and improves temperature consistency
• Downflow cabinet configuration directs conditioned air through the base for slab or crawlspace installs
• Compatible with R454B refrigerant in matched split-system cooling applications
• 3-ton airflow capacity for pairing with appropriately sized cooling equipment

Compatibility

Designed as an OEM modulating downflow gas furnace for residential forced-air heating systems requiring a C-cabinet configuration with R454B-compatible matched cooling equipment.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer instructions. Shut off the gas supply and disconnect electrical power to the system before beginning any service or installation work. Venting must be configured to meet applicable codes, including proper sizing and material for a 97% AFUE condensing furnace, which requires PVC or equivalent approved vent material for flue and combustion-air piping. Verify that the thermostat and control wiring are compatible with modulating furnace operation before startup.
