Weatherking W802W0754A17UHSBAS Gas Furnace 75000 Btu

Product Description

The WEATHERKING W802W0754A17UHSBAS is a natural gas forced-air furnace rated at 75,000 BTU/h with 80% AFUE efficiency. It uses a two-stage burner and an ECM variable-speed blower motor to deliver consistent heat output while reducing energy consumption compared to single-stage, PSC-motor units. At 17 inches wide, the cabinet fits standard upflow and horizontal installations in residential applications. Licensed HVAC technicians install and commission this unit. The two-stage operation allows the furnace to run at a lower first stage under mild conditions, minimizing short-cycling and improving comfort and air distribution across the conditioned space.

This furnace is designed for upflow and horizontal configurations, making it suitable for installations in basements, utility closets, attics, or crawlspace-adjacent air handlers where horizontal discharge is required. The 75,000 BTU/h output targets mid-to-large residential structures and is nominally matched to 4-ton cooling systems when installed as part of a split system. Natural gas supply is required. This unit is intended for residential heating applications where an 80% AFUE non-condensing gas furnace meets local code requirements.

Key Features

• 80% AFUE efficiency rating meets minimum federal efficiency standards for non-condensing gas furnaces
• Two-stage gas valve reduces short-cycling and improves temperature uniformity
• ECM variable-speed blower motor lowers electrical consumption and supports better humidity control
• Upflow and horizontal configuration supports multiple installation orientations
• 17-inch cabinet width fits standard residential furnace openings
• Nominally matched to 4-ton cooling capacity for split-system installations

Compatibility

Designed for upflow and horizontal residential gas furnace installations requiring a 75,000 BTU/h, 80% AFUE, two-stage ECM unit with a 17-inch cabinet width. No specific compatible model numbers or replacement part numbers were provided in the product data.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the National Fuel Gas Code (NFPA 54 / ANSI Z223.1), applicable local mechanical codes, and the manufacturer installation instructions. Shut off gas supply and disconnect electrical power before beginning any service or installation work. Flue venting must be sized and configured for a Category I 80% non-condensing appliance using B-vent or approved single-wall metal vent per local code requirements. Confirm gas supply pressure, thermostat low-voltage wiring, and all duct connections before startup.
