Ge NF80D070S3AR Gas Furnace 80% Afue 70000 Btu 3 Ton

Product Description

The GENERAL ELECTRIC NF80D070S3AR is a single-stage, downflow gas furnace rated at 80% AFUE with a 70,000 BTU/h heating capacity. It uses a constant torque blower motor and is factory-configured for R454B refrigerant system compatibility in matched cooling applications. The unit operates on natural gas and is designed for residential forced-air heating systems. Licensed HVAC technicians install this furnace as a primary heating appliance in new construction or replacement projects where a downflow cabinet orientation is required by the duct configuration.

This furnace is suited for residential applications requiring a downflow installation, typically in homes where the air handler sits above the duct plenum or in closet-style installations. The 3-ton cooling tonnage rating matches it to appropriately sized cooling coils. The single-stage gas valve delivers consistent, straightforward heat output, making it a practical fit for standard-load residential projects. The R454B refrigerant designation indicates compatibility with modern low-GWP refrigerant systems when paired with a matched coil and condensing unit.

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 before beginning any service or replacement work. Downflow furnaces require a correctly sized plenum and floor opening; verify duct dimensions and clearances before setting the unit. Venting must comply with applicable fuel-gas codes, including National Fuel Gas Code (NFPA 54) requirements for flue size and combustion air supply.
