The Keating 22770 Thermopile provides a dependable millivolt power source to support safe ignition and operation in compatible gas-powered equipment. Designed with a 36-inch, two-lead configuration, this thermopile generates between 250 and 750 millivolts by converting heat from the pilot flame into electrical energy through a series of connected thermocouples. This small electrical output powers millivolt gas control systems, allowing burners and safety valves to function without an external power supply. By delivering consistent voltage to the control circuit, it helps maintain reliable ignition performance, supports stable burner operation, and contributes to overall equipment safety and efficiency in commercial kitchen environments.
