General Electric nf80u110s5c Gas Furnace 110K Btu 80% Afue

Product Description

The GENERAL ELECTRIC nf80u110s5c is a single-stage, upflow and horizontal-flow gas furnace rated at 110,000 BTU/h output with 80% AFUE efficiency. It uses a constant torque motor for consistent airflow delivery across variable static pressure conditions. Pre-formed flanges and crimped heat exchangers are standard construction features. The unit ships in gray and is intended for residential or light-commercial forced-air heating systems. Licensed HVAC technicians handle installation and commissioning. At 153 pounds net weight, the cabinet requires a two-person lift for safe positioning.

This furnace is designed for upflow and horizontal installation orientations, giving installers flexibility in attic, closet, or utility-room applications. The Insta-Position Technology allows the unit to be configured for the required airflow direction without major field modification. At 5-ton system capacity and 110K BTU/h, it is sized for larger residential or small commercial applications where high heating output is required in a single-stage firing configuration.
