Resideo 394588/u Lp to Natural Gas Conversion Kit

Product Description

The RESIDEO 394588/u is a single-stage LP-to-natural-gas conversion kit designed for use with Resideo and Honeywell gas valve assemblies in residential and light-commercial heating applications. The kit allows a qualified HVAC technician to convert a compatible gas valve from liquefied petroleum (LP) operation to natural gas operation without replacing the entire valve body. It includes a regulator spring, o-ring, adjustment screw, and cap screw. The pressure regulator setpoint adjusts from 3 inches water column (WC) to 5 inches WC, covering the standard natural gas delivery range for most residential furnace and boiler installations.

This conversion kit is intended for use in residential and light-commercial gas heating systems where an existing compatible gas valve must be reconfigured for natural gas service. It is applicable to standard and slow-opening valve configurations. It is not suitable for step-opening valve configurations. Licensed HVAC technicians and gas-line service professionals perform this conversion as part of fuel-source changeover work on forced-air furnaces, boilers, and similar gas-fired appliances.
