General Electric nf80u070v3a Gas Furnace 70K Btu 80% Afue

Product Description

The GENERAL ELECTRIC nf80u070v3a is a two-stage, 80% AFUE upflow and horizontal-flow gas furnace rated at 70,000 BTU/h and 3 tons of airflow capacity. It uses a variable-speed motor to match heating output to demand, reducing short-cycling and improving comfort across different load conditions. The heat exchanger is crimped rather than welded, a construction method associated with consistent joint integrity at production volume. Insta-Position Technology allows the unit to be repositioned in the field without requiring additional parts, giving installers flexibility during rough-in. This furnace is installed by licensed HVAC technicians in residential forced-air systems.

The nf80u070v3a is designed for residential upflow or horizontal-flow installations where an 80% AFUE gas furnace is required by code or project specification. The unit ships at 130 pounds, with a net installed weight of 120 pounds. Its overall footprint measures 14.5 inches wide, 28.5 inches deep, and 33 inches tall, making it suitable for utility closets, basements, attics, and crawlspace horizontal installations where clearance allows. Pre-formed flanges on the cabinet simplify duct connection during installation.

Key Features

• Variable-speed motor adjusts airflow to match system demand
• 80% AFUE efficiency rating meets standard residential efficiency requirements
• Insta-Position Technology allows field repositioning without additional components
• Crimped heat exchanger construction for consistent joint integrity
• Pre-formed cabinet flanges simplify duct connection at the jobsite

Compatibility

Designed as an OEM-style residential gas furnace for upflow and horizontal-flow forced-air system applications requiring a 70,000 BTU/h, 80% AFUE, two-stage unit at 3 tons of airflow capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the appliance manufacturer instructions. Shut off gas supply and disconnect electrical power before beginning any service or installation work. Venting must be configured per the applicable fuel-gas code, such as the IFGC, using the correct vent category and connector materials for an 80% AFUE non-condensing appliance. Confirm all gas connections are leak-tested before commissioning the unit.
