Williams 7720 Conversion Kit
When transitioning a 50,000 BTU Williams Forsaire furnace from natural gas to liquid propane, using the Williams 7720 conversion kit (Part #50086) is the standard for maintaining proper manifold pressure and orifice sizing. This Williams gas conversion kit is engineered for specific compatibility with Williams 50086 series dual-wall counterflow furnaces manufactured after 2013. For technicians in the field, this kit provides a complete set of OEM HVAC replacement parts, including the necessary burner orifices and a pressure regulator spring to recalibrate the gas valve for the higher energy density of propane. Ensuring a natural gas to LP conversion with original equipment components is the best way to safeguard the burner’s ignition characteristics and thermal throughput. Proper installation of this liquid propane conversion kit requires verifying the furnace’s serial number—where the third and fourth digits denote the manufacturing year—to confirm the 7720 kit matches the internal valve assembly requirements.
Key Benefits of the Williams 7720 Conversion Kit- Engineered Compatibility: Specifically designed for 50,000 BTU 50086 series Forsaire furnaces.
- Complete Component Set: Includes main burner orifices and regulator springs for a precise LP transition.
- Optimal Performance: Re-calibrates gas flow to maintain factory-spec heating output on propane fuel.
- After-2013 Optimization: Tailored for modern Williams valve assemblies and ignition systems.
Is the 7720 kit compatible with furnaces made before 2013?
No, this specific kit is optimized for units manufactured from 2013 onward. For older units, check the serial number to find the appropriate legacy conversion part.
Does this kit include a pilot orifice?
Yes, the 50086 series conversion requires a specific pilot orifice adjustment or replacement included in the kit to ensure consistent flame sensing and ignition.
Can I use this for other BTU ratings?
This kit is strictly calibrated for 50,000 BTU models; using it on lower or higher capacity burners will cause improper gas-to-air ratios and potential safety hazards.
This item is not eligible for free shipping.
