General Electric nf80u070s3br Gas Furnace 70000 Btu/h 80% Afue

Product Description

The General Electric nf80u070s3br is an 80% AFUE single-stage gas furnace rated at 70,000 BTU/h with a 3-ton blower capacity, designed for upflow and horizontal flow installations. It ships with the RDSC integrated control board factory installed, reducing field labor on startup. The constant torque motor supports efficient airflow management across varying static pressure conditions. Compatible with R410A and R454B refrigerant systems when applied in combination cooling configurations, the unit is built for residential forced-air heating applications and is sized for B cabinet installations. Licensed HVAC technicians handle installation and startup on this equipment.

The nf80u070s3br fits residential new-construction and replacement applications where an upflow or horizontal furnace orientation is required. The B cabinet width of 17.5 inches suits standard residential air handler closets and utility rooms. Single-stage heating operation pairs well with conventional thermostats and existing low-voltage wiring. The unit supports R410A and R454B compatible cooling coils when the system is configured as a split system. Emissions meet standard emissions classification for residential gas heating equipment.
