Weatherking W962W1155A24M4SBAS Gas Furnace 115000 Btu

Product Description

The WEATHERKING W962W1155A24M4SBAS is a multi-position, two-stage natural gas furnace rated at 115,000 BTU/h input with 96% AFUE. That high-efficiency rating means the unit extracts nearly all usable heat from combustion, keeping fuel costs down and satisfying modern efficiency codes in most jurisdictions. The two-stage gas valve and variable-speed blower work together to deliver consistent comfort at reduced fire on mild days and full capacity when outdoor temperatures drop. This furnace is installed by licensed HVAC technicians in residential and light-commercial forced-air heating systems.

The W962W1155A24M4SBAS is sized at 5 nominal tons of airflow capacity, making it appropriate for larger residential applications or small commercial spaces requiring high-BTU output with matched air distribution. The multi-position design allows installation in upflow, downflow, or horizontal orientations, giving installers flexibility when working with existing ductwork layouts or new construction builds. The unit runs on natural gas and is built around a constant-CFM blower strategy that maintains airflow targets across varying static pressure conditions.

Key Features

• 96% AFUE rating for high-efficiency natural gas combustion
• 115,000 BTU/h input capacity suited for large residential or light-commercial loads
• Two-stage gas valve reduces fuel consumption and cycling on mild days
• Multi-position configuration supports upflow, downflow, and horizontal installations
• Constant-CFM variable-speed blower maintains airflow across varying duct static pressure
• 5-ton nominal airflow capacity matches high-capacity cooling coil installations

Compatibility

Designed as an OEM-style replacement or new-installation furnace for forced-air natural gas heating systems requiring a multi-position, two-stage, high-efficiency unit at 5-ton nominal airflow capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the International Fuel Gas Code (IFGC), local mechanical codes, and the manufacturer installation instructions. Shut off the gas supply and disconnect electrical power before servicing or connecting the unit. Verify flue venting is sized and routed correctly for a 96% AFUE condensing furnace, as this unit requires a properly pitched PVC condensate drain and approved intake and exhaust venting. Do not operate the furnace without all panels secured and a confirmed gas-tight connection at the supply line.
