The Williams Comfort Products P043801 Pilot Generator/Thermopile Thermocouple is a part of gas powered HVAC systems that creates millivoltage power to operate gas valves without external electricity. The pilot generator used is a thermopile type compatible with many Williams Comfort Products wall furnaces and room heaters. This converts the pilot flame's heat to electrical energy and in itself it is working safely and has a long life. Its main features include energy efficiency, safety and dependable performance and therefore is suitable for maintaining constant heating in residential or light commercial applications with pilot ignition systems.
