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)

It serves as the primary communication hub between the thermostat and high-voltage components

Enhanced Combustion: Helps achieve the proper fuel-to-air ratio

Diagnostic Reliability: Prevents common failure modes where the blower runs at maximum speed incorrectly during low-demand cycles
