Weatherking W801CA075521ZSA Gas Furnace 80% 75000 Btu Ecm

Product Description

The WEATHERKING W801CA075521ZSA is an 80% AFUE single-stage residential gas furnace with a constant torque electronically commutated motor (ECM). It delivers 75,000 BTU/h of heating output using natural gas. The aluminized steel heat exchanger resists corrosion and thermal fatigue, and is removable for straightforward field serviceability. The 34-inch low-profile cabinet is designed for installations where vertical clearance is limited. Direct spark ignition (DSI) provides reliable, consistent ignition. Licensed HVAC technicians typically handle installation and commissioning of this equipment.

This furnace is rated for residential applications and is configured for upflow or horizontal airflow orientation. The integrated control board includes dip switches for simplified system setup, a 7-segment LED display for diagnostics, and a QR code for quick access to product documentation from a mobile device. It is suited for new construction and retrofit installations in homes requiring a medium-capacity single-stage heating system with ECM blower performance.

Compatibility

Designed as an OEM-style replacement or new-installation furnace for residential gas heating systems requiring an upflow or horizontal configuration at 75,000 BTU/h and 80% AFUE.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer instructions. Shut off the gas supply and disconnect electrical power before servicing or replacing any components. Venting must comply with applicable fuel gas code requirements for 80% non-condensing appliances, typically using B-vent or single-wall metal vent as permitted. Verify thermostat wiring and dip switch settings on the integrated control board before startup.
