General Electric nf80d110s5c Gas Furnace 110K Btu 80% Afue

Product Description

The GENERAL ELECTRIC nf80d110s5c is a single-stage downflow gas furnace rated at 110,000 BTU/h with 80% AFUE efficiency. It uses a constant torque motor for reliable, consistent airflow and features Insta-Position Technology for flexible installation orientations. Pre-formed flanges and crimped heat exchangers support a robust build intended for long service life. This furnace is installed by licensed HVAC technicians in residential and light commercial applications where a high-capacity downflow configuration is required.

The nf80d110s5c is designed for downflow installations, making it well suited for applications where supply air is delivered beneath the unit, such as homes with under-floor duct systems or platforms in utility rooms. With a 5-ton capacity and 110,000 BTU/h output, it is appropriate for larger residential spaces or small commercial buildings requiring substantial heating capacity at standard efficiency. The constant torque motor supports stable performance across varying static pressure conditions common in these systems.
