Resideo 396021 Conversion Kit

The Resideo 396021 Conversion Kit is a field-proven solution designed to convert two-stage gas valves from natural gas to liquid propane (LP). Specifically engineered for compatibility with VR820xQ, VR830xQ, VR820xN, and VR830xN series gas controls, this kit enables precise pressure regulation within an 8" to 11" WC adjustment range. As a direct replacement for part number 90-396021, it ensures seamless integration during system retrofits or fuel conversions. The kit includes a high-tension regulating spring, a durable O-ring, and a precision adjustment screw, necessitating the reuse of the existing cap screw from the original valve assembly. Technicians rely on this LP conversion kit for its consistent manifold pressure delivery and robust seal integrity in demanding heating applications. Utilizing this OEM-grade hardware ensures that the burner orifice and valve modulation maintain peak combustion efficiency across both stages of operation, preventing common ignition issues associated with improper fuel mixtures.

Common Questions

Can I use this kit on a single-stage gas valve?
No, the 396021 is specifically designed for two-stage gas valves. Using this on a single-stage valve will result in improper pressure regulation and potential safety hazards.

Are there any parts I need to retain from the original setup?
Yes, you must reuse the existing cap screw from the gas valve being converted, as it is not included in this kit.

What is the difference between 396021 and 90-396021?
These parts are functionally identical and interchangeable; the variation in part numbers is due to regional packaging or legacy numbering systems.
