Resideo 393691 Conversion Kit

Professional-grade Honeywell 393691 conversion kits are engineered for the field conversion of single-stage gas valves from natural gas to liquefied petroleum (LP/Propane). This technical kit is essential for equipment transitions, featuring a specialized red regulator spring that achieves a precise LP gas pressure manifold adjustment range between 8" and 12" WC. The package includes the critical natural gas to LP conversion components: the regulator spring, O-ring, adjustment screw, and protective cap screw, ensuring a hermetic seal and reliable pressure regulation.

Compatibility is strictly limited to single-stage combination gas controls. The 393691 is validated for use with Honeywell VR8200, VR8300, VR8104, VR8204, VR8304, VR8205 (standard only, excluding VR8205S), VR8305, VR4200, VR4300, VR4204, VR4304, VR4205, and VR4305 series. It is designed specifically for standard and slow opening gas valves. Note that this kit is not compatible with step-opening valves or two-stage systems. The 393691/U model is the universal trade equivalent, sharing identical technical specifications and performance characteristics with the base 393691 part number.

• Precise Pressure Management: Specifically calibrated to maintain an 8" to 12" adjustment range for stable LP combustion.
• Comprehensive Component Matching: Includes all necessary hardware—O-ring, spring, and adjustment screw—for a complete regulator swap.
• Broad Series Compatibility: Fits a wide range of industry-standard VR8200 and VR8300 series valves found in residential and light commercial equipment.
• Direct OEM Replacement: Ensures factory-spec performance when converting Honeywell/Resideo controls.

Can I use the 393691 kit on a step-opening valve?
No. Step-opening valves require a different regulation profile. This kit is strictly for standard and slow-opening single-stage valves.

What is the difference between 393691 and 393691/U?
There is no technical difference. The "/U" designation indicates universal packaging for trade distribution, but the components and specifications are identical.

Is this kit suitable for 2-stage furnaces?
No. This kit is designed only for single-stage combination gas controls. Two-stage valves require a multi-stage conversion kit to handle high and low fire settings.
