Description
The Weil McLain 510-811-640 Natural Gas Pilot Assembly W/Bracket & Thermocouple is an ignition and flame sensor that initiates and maintains pilot flame operation in gas-fired heating equipment. It operates by directing a controlled flow of natural gas to the pilot burner, where it is ignited, while the integrated thermocouple monitors flame presence and signals the gas valve to remain open for safe operation. In HVAC systems, it is used in boilers and gas heating units to support reliable ignition and continuous flame supervision. It includes a mounting bracket for secure positioning and supports safe combustion.
