This Rheem component is a pilot assembly designed to ignite the gas in a water heater. It is an integral part of the ignition system, providing a reliable and consistent flame to initiate the heating process. The assembly includes a thermocouple and thermopile, which are safety devices that detect whether the pilot light is on. If the pilot light goes out, these components signal the gas valve to shut off, preventing unburned gas from accumulating. This Rheem pilot assembly is compatible with select models of Rheem water heaters and is made from durable materials for long-lasting performance.
