Williams 8941 Conversion Kit

The Williams 8941 Natural Gas to LP Conversion Kit is a critical genuine OEM component package engineered for field-converting specific gas-fired heating equipment. This kit is specifically designed for Williams 30038 Series Direct Vent Furnaces with a 30,000 BTU rating. To ensure field compatibility, verify the manufacture date of the host unit via the serial number; this kit is compatible with Williams Furnace Company heaters manufactured after 2013. For older units, the internal manifold and valve configurations differ, and this kit will not provide the necessary combustion characteristics for safe operation.

When performing a Williams furnace gas conversion, using OEM-spec parts like the 8941 ensures the correct orifice sizing and regulator adjustments required to maintain proper manifold pressure. This transition from Natural Gas to Liquid Propane is essential for installations where local utility infrastructure is unavailable. As a veteran-grade HVAC replacement part, it guarantees that the burner flame profile and heat exchanger thermal transfer remain within original design parameters after the fuel source switch.

Key Benefits for Technicians

• Maintains Combustion Efficiency: Prevents sooting and incomplete combustion by providing precision-drilled orifices sized for 30,000 BTU LP applications.
• Direct Fit Compatibility: Specifically matched to the 30038 Series valve train, reducing troubleshooting time during installation.
• OEM Reliability: Built with factory-validated materials to ensure long-term pressure regulation stability without drifting.
• System Integrity: Preserves the original heating performance and air-to-fuel ratio oversight intended by the manufacturer.

Common Questions Regarding the Williams 8941

How do I verify if my furnace was made after 2013?
Check the serial number on the rating plate. The first two digits represent the manufacturing week, and the third and fourth digits represent the manufacturing year. If the third and fourth digits are 13 or higher, this kit is compatible.

Can I use this kit on a 22,000 BTU or 40,000 BTU model?
No, this LP gas conversion kit is calibrated specifically for the 30,000 BTU flow rate. Using it on different BTU ratings will result in improper combustion, potentially causing high carbon monoxide levels or equipment damage.

Does this kit include the gas valve regulator spring?
Yes, this genuine Williams 8941 kit includes the necessary components to convert the gas valve and the burner orifice for a complete fuel transition.
