Oxbox J962V080CU4SA Gas Furnace 80000 Btu/h 96% Afue Two-stage Variable Speed Ecm Residential

Product Description

The Oxbox J962V080CU4SA is a residential gas furnace rated at 80,000 BTU/h with a 96% Annual Fuel Utilization Efficiency (AFUE) rating. It operates on a two-stage heating configuration and uses a variable-speed ECM blower motor to modulate airflow based on demand. These two design elements work together to reduce short-cycling, lower energy consumption, and maintain more consistent indoor temperatures. Licensed HVAC technicians install this unit as the indoor heating component of a split system, typically paired with a matched outdoor condensing unit and cased evaporator coil. The high AFUE rating means the furnace converts 96 cents of every fuel dollar into usable heat, making it a strong performer for residential heating loads.

The J962V080CU4SA is suited for residential split-system HVAC installations where a gas furnace serves as the air handler and primary heat source. It has been specified as a matched furnace component in Oxbox system combinations that include outdoor condensing units such as the J5AC3024A1000AA and J5AC3048A1000AA, as well as cased coil models including J5GXCC005AC6HUA, J5MXCC009AC6HCA, and J5MXCC017AC6HCA. These pairings cover 2-ton through 4-ton system configurations. The furnace is intended for upflow or compatible-position installation in typical residential mechanical rooms, closets, or utility spaces.

Compatibility

The J962V080CU4SA has been specified as the furnace component in matched Oxbox split systems alongside outdoor units J5AC3024A1000AA, J5AC3048A1000AA, and J5AC5048A1000AA, and cased coil models J5GXCC005AC6HUA, J5MXCC009AC6HCA, and J5MXCC017AC6HCA, covering 2-ton through 4-ton system configurations.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes, the National Fuel Gas Code (NFPA 54), and the manufacturer installation instructions. Shut off gas supply and disconnect electrical power before beginning any service or installation work. The ECM blower motor requires correct low-voltage control wiring to operate in variable-speed mode; verify thermostat and control board compatibility before startup. Do not operate the furnace before completing duct connections, verifying flue venting integrity, and confirming proper gas line pressure at the inlet.
