General Electric NF96D070S4B Downflow Gas Furnace 96% Afue

Product Description

The GENERAL ELECTRIC NF96D070S4B is a single-stage downflow gas furnace rated at 70,000 BTU/h with a 96% AFUE efficiency rating. Built for forced-air heating systems, this furnace delivers high-efficiency combustion suited to residential installations where the air handler discharges downward into the supply duct. At 4-ton capacity and 96% AFUE, it meets the efficiency thresholds required in many regional energy codes. Licensed HVAC technicians handle installation, sizing, venting, and gas line connection for this class of equipment.

This furnace is designed for downflow installations, making it appropriate for applications where the furnace sits above the conditioned space or in an attic platform configuration with ductwork routed downward. The single-stage burner operates at one fixed firing rate, providing straightforward control integration with standard thermostat systems. It is suited to residential new-construction and replacement projects requiring a high-efficiency gas furnace in a downflow cabinet configuration.

Key Features

• 96% AFUE rating for high-efficiency natural gas heating
• 70,000 BTU/h heating capacity
• Single-stage burner operation for simplified controls compatibility
• Downflow cabinet configuration for overhead or platform installations
• 4-ton rated airflow capacity

Compatibility

Designed as an OEM-style downflow gas furnace for residential forced-air heating systems requiring a single-stage, high-efficiency unit in a downflow cabinet configuration.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the International Fuel Gas Code (IFGC). Shut off the gas supply and disconnect electrical power before beginning any work on existing equipment. Proper venting must be confirmed for a 96% AFUE condensing furnace, which requires PVC flue and condensate drain connections. Do not operate the unit without verifying gas pressure, venting integrity, and all electrical connections are complete and correct.
