Oxbox J962V120DU5SA Gas Furnace 120000 Btu/h 96 Afue Two-stage Variable Speed Ecm Upflow Horizontal

Product Description

The Oxbox J962V120DU5SA is a two-stage, variable-speed gas furnace rated at 120,000 BTU/h with a 96% AFUE efficiency rating. It uses an ECM (electronically commutated motor) blower drive, which reduces electrical consumption compared to standard PSC motors while delivering consistent airflow across both heating stages. The furnace is configured for upflow and horizontal installation and fits a D-width cabinet footprint. Licensed HVAC technicians install this unit as the heating component in residential split systems, often paired with a matched outdoor condensing unit or heat pump.

The J962V120DU5SA is suited for residential gas heating applications where high efficiency and two-stage capacity control are priorities. Two-stage operation allows the furnace to run at a reduced firing rate during moderate demand, improving comfort and reducing short-cycling. The horizontal left and horizontal right installation flexibility makes it a practical choice for attic, crawlspace, and closet installations where upflow orientation is not possible. It operates on a 115V/1-phase/60 Hz electrical supply.

Key Features

• 96% AFUE two-stage gas heating for high-efficiency residential performance
• 120,000 BTU/h heating capacity for larger residential applications
• Variable-speed ECM blower motor reduces electrical draw and improves airflow control
• Upflow and horizontal left/right installation configurations supported
• D-width cabinet for compatibility with standard residential equipment openings
• 115V/1-phase/60 Hz electrical supply

Compatibility

The J962V120DU5SA has been paired in documented split-system configurations with Oxbox outdoor condensing units including R-454B models in 3.5-ton and 4-ton sizes. Designed as an OEM-style upflow/horizontal gas furnace replacement for residential split systems requiring a D-cabinet, two-stage, 120,000 BTU/h heating section.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the appliance manufacturer's instructions. Shut off gas supply and disconnect electrical power before servicing or replacing any furnace components. The IFGC governs gas piping connections and venting requirements; verify vent category and flue pipe sizing before installation. ECM motor systems require correct low-voltage control wiring and a compatible thermostat to operate properly across both heating stages.
