General Electric nf80u135s5dr Gas Furnace 135K Btu 5 Ton

Product Description

The GENERAL ELECTRIC nf80u135s5dr is a single-stage, upflow and horizontal-flow gas furnace rated at 80% AFUE and 135,000 BTU/h output capacity. Built in the D cabinet configuration, this unit is designed for larger residential or light commercial heating applications where a high-capacity, natural-draft or induced-draft furnace is required. The 80% AFUE rating meets federal minimum efficiency standards for non-weatherized gas furnaces. Licensed HVAC technicians typically size and install this unit as part of a complete forced-air heating system.

The nf80u135s5dr is suited for upflow or horizontal installation, giving installers flexibility in mechanical room, utility closet, or attic configurations. The D cabinet designation indicates a wider chassis, appropriate for systems requiring a 5-ton nominal airflow match. This furnace is intended for residential or light commercial forced-air systems where single-stage heating control and high BTU output are specified by the mechanical design.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and IFGC requirements. Shut off gas supply and disconnect electrical power before any service or connection work.
