Product Description

The A.O. SMITH 100109217 is a natural gas control valve kit designed for use in gas-fired water heater systems. The control valve regulates gas flow to the burner assembly, enabling safe ignition, temperature control, and shutdown functions. This kit serves as a direct OEM-style replacement for the original component, restoring proper operation to systems that have experienced valve failure or degradation. Installation is typically performed by a licensed plumber or gas technician following local codes and manufacturer guidelines.

This kit is intended for residential and light-commercial gas water heater applications running on natural gas. It is suited for service calls where the existing control valve has failed to maintain set temperature, shows signs of gas valve malfunction, or has been flagged during inspection. The kit format provides the components needed for a complete valve replacement in a single package.
