Oxbox J962V100CU5SA Two-stage Gas Furnace 100000 Btu 96% Afue Upflow Horizontal

Product Description

The Oxbox J962V100CU5SA is a two-stage, upflow and horizontal-right/left gas furnace rated at 100,000 BTU/h with 96% AFUE efficiency. It features a constant-torque ECM blower motor and a 21-inch cabinet width, making it well suited for residential forced-air heating systems where high efficiency and quiet, variable-output operation are required. The two-stage gas valve reduces output during mild conditions, cutting cycling losses and improving comfort. Licensed HVAC technicians install and commission this unit as part of a split system or dual-fuel configuration.

The J962V100CU5SA fits residential applications where upflow or horizontal-right/left airflow orientation is required. It has appeared as the gas furnace component in complete split systems paired with Oxbox condensers and cased evaporator coils, including configurations with R454B air conditioning equipment. It is also used in dual-fuel heat pump setups where the furnace serves as the backup heating source during low ambient conditions. Cabinet width of 21 inches suits standard C-cabinet installations common in closet or utility room placements.

Key Features

• 96% AFUE two-stage combustion reduces fuel consumption during partial-load heating cycles
• 100,000 BTU/h heating capacity for larger residential applications
• Constant-torque ECM blower motor supports variable airflow and reduces electrical draw compared to PSC motors
• Upflow and horizontal-right/left configuration provides flexible installation orientation
• 21-inch cabinet width fits C-cabinet cased coil pairings
• Compatible with dual-fuel heat pump system configurations as the backup gas heat source

Compatibility

The J962V100CU5SA has been used as the gas furnace component in Oxbox split systems alongside condensers including the J5AC3030A1000AA, J5AC3042A1000AA, and J5AC3048A1000AA, and with cased coils including the J5MXCC005AC6HCA and J5MXCC009AC6HCA. It has also been included in dual-fuel heat pump configurations with the J5HP5042A1000AA outdoor unit. Verify airflow, static pressure, and electrical requirements against the full system submittal before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local 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. Confirm flue venting is sized and routed per applicable codes for a 96% AFUE condensing furnace, including proper condensate drainage for the secondary heat exchanger. Do not operate the furnace without verifying gas pressure, heat exchanger integrity, and correct airflow direction for the chosen installation orientation.
