General Electric nf80u110t5c Gas Furnace 110K Btu 80% Afue

Product Description

The GENERAL ELECTRIC nf80u110t5c is a two-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 performance across varying static pressure conditions. The heat exchanger is crimped rather than welded, a construction method that reduces stress points and is integral to the long-term durability of the unit. Insta-Position technology and pre-formed flanges allow for faster field positioning during installation. This furnace is designed for installation by licensed HVAC contractors in residential and light-commercial applications where natural gas heating is required.

The nf80u110t5c is rated for 5-ton equivalent airflow capacity and is suited for upflow or horizontal-flow configurations, giving installers flexibility in equipment closets, utility rooms, attic spaces, and crawlspace-adjacent installations. The two-stage heating operation allows the furnace to run at a lower stage during mild conditions, reducing short-cycling and improving comfort distribution throughout the structure. Standard emissions classification makes it compliant for use in most jurisdictions without additional emissions equipment.

• Limited lifetime heat exchanger warranty with registration

Compatibility

Designed as an OEM-style upflow and horizontal-flow gas furnace for residential and light-commercial forced-air heating systems requiring a 5-ton, 110,000 BTU/h, 80% AFUE two-stage unit.

Installation Notes

Installation must be performed by a licensed HVAC contractor in accordance with local mechanical codes and IFGC requirements. Shut off gas supply and disconnect electrical power before beginning any service or installation work. Verify that venting, flue sizing, and combustion air provisions meet current code requirements for an 80% AFUE non-condensing furnace. Do not alter factory-crimped heat exchanger connections or pre-formed flange assemblies in the field.
