Honeywell 396221 Conversion Kit

The Honeywell 396221 Conversion Kit is a critical field component for technicians needing to transition single-stage gas valves from natural gas to LP (liquid propane). Engineered for a precise 8" to 12" adjustment range, this kit is specifically compatible with the Honeywell VR8200, VR8300, SV9500, and SV9600 families, including popular series like the VR8205S and VR8215T. This assembly, often labeled as 396221/U, ensures the manifold pressure is properly regulated for propane’s higher BTU content. The kit includes a high-tensile regulator spring, a replacement adjustment screw, and a vital O-ring to maintain a gas-tight seal. Professionals should note that while this kit supports standard and slow opening gas valves, it is not for use with step-opening valves or two-stage systems. Correct installation requires re-using the existing cap screw to finish the assembly and verifying pressure settings with a manometer to ensure safe combustion cycles.

• Universal Compatibility: Fits a wide range of Honeywell and Resideo VR-series combination gas controls.
• Precise Pressure Control: Features an 8-12 inch water column (WC) adjustment range for stable LP gas delivery.
• Simplified Installation: Includes the core LP gas conversion parts needed to modify the regulator without replacing the entire valve.
• Industrial Durability: Components are built to handle the corrosive properties of liquid propane in high-cycle environments.

• Is the 396221/U different from the 396221? No, they are technically identical; the "/U" suffix simply denotes universal packaging for retail and wholesale distribution.
• Can I use this for a 2-stage furnace? No, this kit is exclusively designed for single-stage natural gas to LP conversions and will not function with two-stage or step-regulator valves.
• Does this kit include the orifices? This specific kit contains the regulator conversion components (spring and screw). Burner orifices must be sized according to the appliance manufacturer’s BTU ratings and altitude charts.
