Description
The Weil McLain 511-724-254 Screw-In Natural Gas Thermocouple 30″ is a sensor that is installed in heating appliances to sense the existence of a pilot flame. It produces a small electrical signal when there is heat, and the gas valve can only be left open when there is a flame. This thermocouple is used in domestic and commercial gas-fired boilers, furnaces, and water heaters. In the HVAC systems, it is used to maintain the operation of the system by making sure that the gas does not reach unlit burners, which maintains the necessary ignition and combustion control.
