The Jade Range 8800000012 Thermopile provides a reliable millivolt power source to support safe ignition and operation in compatible gas equipment. Manufactured by Jade Range, this 36-inch thermopile features a two-lead design and produces an output range of 250–750 millivolts. It works by converting heat from the pilot flame into a small electrical current through a series of thermocouples connected together. This generated voltage powers the gas control system, allowing the burner to operate without an external electrical supply. Its dependable heat-to-electric conversion helps ensure steady ignition performance, supports safe gas flow control, and contributes to consistent equipment operation.
