Weatherking W801T0753A17DZSNAS Downflow Gas Furnace 75K Btu

Product Description

The WEATHERKING W801T0753A17DZSNAS is a single-stage, downflow natural gas furnace rated at 75,000 BTU/h with 80% AFUE efficiency. It is equipped with an electronically commutated motor (ECM) for variable-speed blower operation, which improves airflow consistency and reduces electrical consumption compared to standard PSC motors. This furnace is designed for residential forced-air heating systems where the air handler is positioned above the ductwork and conditioned air is discharged downward. Installation and commissioning are typically performed by a licensed HVAC technician.

This furnace is sized for applications requiring approximately 3 nominal tons of cooling coil compatibility, making it well suited for mid-size residential installations. The downflow configuration is commonly used in homes with crawl-space or slab-on-grade duct systems, utility closets, or alcove installations where a bottom-discharge layout is required. The single-stage gas valve delivers full rated capacity on every call for heat, providing straightforward, reliable operation.
