Oxbox J801V100CM5SEB Single Stage Gas Furnace 100000 Btu 80% Afue Ecm Motor C Cabinet Multi-positional

Product Description

The Oxbox J801V100CM5SEB is a single-stage, multi-positional gas furnace rated at 100,000 BTU/h output with 80% Annual Fuel Utilization Efficiency (AFUE). Designed for residential forced-air heating systems, this unit runs on natural gas and uses an ECM (electronically commutated motor) blower motor to deliver quieter, more energy-efficient airflow compared to standard PSC motors. The C-cabinet width of 21 inches fits a range of residential installations. Licensed HVAC technicians install and commission this furnace as part of a complete heating or heating-and-cooling system.

This furnace is built for upflow, downflow, and horizontal right or left airflow configurations, making it adaptable to attic, basement, closet, and crawlspace installations. The single-stage burner operation provides straightforward, reliable heating for residential applications where variable-capacity control is not required. The unit replaces the earlier J801V100CM5SEA in the same product family, giving technicians a direct drop-in successor for ongoing projects and warranty replacements.

Key Features

• 80% AFUE rated efficiency on natural gas — meets minimum federal efficiency standards for residential furnaces
• ECM blower motor at 1/2 horsepower with 5 speed modes for improved airflow control and reduced electrical draw
• Multi-positional installation: upflow, downflow, horizontal left, and horizontal right
• C cabinet at 21 inches wide accommodates standard residential duct configurations
• Single-stage operation for straightforward thermostat integration and reliable ignition sequencing
• Centrifugal metal blower wheel, 11-3/16 inches diameter, for durable air movement

Compatibility

The J801V100CM5SEB is the direct replacement for J801V100CM5SEA. It is designed for residential gas heating applications and is compatible with standard low-voltage thermostat controls and split-system cooling coils that match the C-cabinet width. Verify duct sizing and static pressure requirements against the unit specifications before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with ANSI Z223.1 / NFPA 54, local mechanical codes, and the manufacturer installation instructions. Shut off gas supply and disconnect electrical power before any service work on the unit or duct connections. Vent sizing and termination must comply with the applicable code for the vent diameter used; this unit supports 3-inch or 4-inch vent pipe. Do not modify burner orifices, gas valve settings, or blower speed configuration outside of the published setup procedure.
