Ao Smith 100112338 Gas Control Valve Kit Lp Gas

Product Description

The AO SMITH 100112338 is a replacement gas control valve kit configured for liquid propane (LP) fuel systems. The gas control valve is a primary safety and regulation component in a water heater, managing gas flow to the burner assembly and integrating thermostat and pilot functions in a single unit. This kit is intended for licensed plumbers and HVAC technicians performing service or warranty replacement on LP gas water heaters. It restores factory-level gas regulation and safety shutoff function when the original valve has failed or been condemned.

This kit is used in liquid propane water heater applications where the original gas control valve has reached end of service life or has been identified as faulty during a service call. LP gas systems operate at different inlet pressures and orifice sizing than natural gas units, making fuel-type-specific replacement essential. This part is designated as a direct replacement component for applicable AO SMITH water heater installations.

Key Features

• Configured specifically for liquid propane (LP) gas service
• Replacement-grade component restoring OEM gas regulation function
• Integrates gas flow control, thermostat, and pilot safety functions typical of combination valve designs
• Designed for straightforward swap-out during field service calls

Compatibility

Designed as an OEM-style replacement gas control valve for AO SMITH liquid propane water heaters requiring a direct valve kit substitution.

Installation Notes

Installation should be performed by a licensed plumber or qualified gas technician in accordance with local codes and the IFGC. Shut off the LP gas supply at the tank or service valve and allow the unit to cool before beginning any valve replacement work. Verify that the replacement valve is rated for LP gas before installation, as natural gas and LP valves are not interchangeable. Leak-test all connections with an approved gas leak detection solution after installation and before restoring power or relighting the pilot.
