General Electric nf80d070s3a Downflow Gas Furnace 70K Btu

Product Description

The GENERAL ELECTRIC nf80d070s3a is an 80% AFUE single-stage downflow gas furnace rated at 70,000 BTU/h with a 3-ton cooling coil cabinet (A Cab). It delivers reliable forced-air heating in residential applications where ductwork is routed below the unit. The downflow configuration directs conditioned air downward through the supply plenum, making it the correct choice for installations on main floors with duct systems running through a crawlspace or slab. Licensed HVAC technicians handle installation and commissioning of this equipment.

The nf80d070s3a is designed for residential downflow installations where an A-cabinet evaporator coil is paired for combined heating and cooling. The 80% AFUE rating means 80 cents of every fuel dollar converts to usable heat, meeting minimum federal efficiency standards for non-weatherized gas furnaces. The single-stage gas valve operates at full fire only, providing straightforward control logic compatible with standard single-stage thermostats. This unit suits typical residential homes requiring a mid-range heating capacity.

Key Features

• 80% AFUE efficiency rating meets federal minimum standards for non-weatherized furnaces
• 70,000 BTU/h heating capacity suited to mid-size residential applications
• Single-stage operation simplifies thermostat wiring and control integration
• Downflow airflow configuration for installations requiring downward supply discharge
• A-cabinet (A Cab) chassis accommodates standard A-coil evaporator for split-system cooling

Compatibility

Designed as an OEM-style downflow gas furnace for residential split-system heating and cooling applications requiring an A-cabinet coil configuration and 70,000 BTU/h single-stage heating capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the manufacturer instructions, local mechanical codes, and IFGC requirements. Shut off gas supply and disconnect electrical power before any service or installation work. The downflow orientation requires a combustible-floor base or listed sub-base when installed over combustible flooring. Verify gas supply pressure, flue venting, and electrical supply voltage and ampacity before commissioning.
