General Electric nf80u070t3ar Gas Furnace 70000 Btu/h 80 Afue

Product Description

The GENERAL ELECTRIC nf80u070t3ar is a two-stage, upflow and horizontal-flow gas furnace rated at 70,000 BTU/h output with 80 percent AFUE efficiency. Two-stage operation means the burner runs at a lower fire setting during mild conditions and steps up to full capacity when the load demands it, reducing short-cycling and improving comfort. The A cabinet designation indicates a specific width profile sized to fit standard residential duct systems. Licensed HVAC technicians install and commission this unit in accordance with local mechanical codes and the manufacturer's instructions.

This furnace is suited for residential forced-air heating applications where upflow or horizontal discharge configurations are required. The A cabinet footprint fits utility closets, alcoves, and attic horizontal installations common in single-family and light commercial residential construction. A 3-ton rated airflow capacity matches the unit to typical 2.5-to-3-ton cooling coil assemblies when used in a combination heating and cooling system. The two-stage burner is well suited for climates with extended periods of moderate cold, where single-stage units tend to over-cycle.

Key Features

• 80 percent AFUE rating meets federal minimum efficiency standards for non-weatherized gas furnaces
• Two-stage burner reduces short-cycling and supports more even temperature distribution throughout the structure
• Upflow and horizontal installation orientations supported within the same cabinet
• A cabinet width profile designed to fit standard residential duct openings
• 3-ton airflow capacity for compatibility with matched cooling coil assemblies

Compatibility

Designed as an OEM-style residential gas furnace for upflow and horizontal forced-air duct systems requiring an A cabinet form factor with 70,000 BTU/h heating capacity and 80 percent AFUE.

Installation Notes

Installation must be performed by a licensed HVAC contractor in compliance with the International Fuel Gas Code (IFGC), local mechanical codes, and the manufacturer's installation instructions. Shut off the gas supply and disconnect electrical power before servicing or replacing any furnace components. Proper venting using approved flue pipe materials and clearances is required for safe operation of an 80 percent non-condensing appliance. Do not attempt to modify the gas valve, burner orifices, or blower assembly without specific manufacturer guidance.
