The Fire By Design 12" Field Serviceable Thermopile Replacement for Pilot Burner Assembly TP12-FS is a high-quality replacement component for the AWEIS primary pilot burner assembly. Available in multiple sizes, this hot surface igniter allows for simple, reliable ignition of your fuel source. A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel.

Thermocouples operate by measuring the temperature differential from their junction point to the point at which the thermocouple output voltage is measured. When a closed circuit consists of more than one metal and has a difference in temperature between junctions and transitions between metals, a current is generated as if there were a difference in potential between the hot and cold junctions.
