For easy installation and reliable performance, Honeywell thermopile generators are the brand of choice. The Honeywell Q313A thermopile generator features a push-in clip, split nut and adapter assembly for easy pilot burner installation. And it’s available in a variety of lead lengths to help you meet the needs of most millivolt heating applications.

Q309, Q340, and Q390 Thermocouples generate a thermoelectric current that senses a pilot flame on gas-fired heating systems. The pilot flame heats the tip of the thermocouple, producing a temperature differential between it and the base. This temperature difference generates a small amount of DC power, measured in millivolts.

Q335 Thermocouple is a quick dropout thermocouple used in conjunction with the Q313 Thermopile Generator in the Q382 Pilot Burner. The flame in the pilot burner is directed toward the thermocouple and the thermopile. As long as pilot flame is present, the millivolt output from the thermocouple keeps the safety valve in the gas control open, allowing the main gas to flow to the appliance on demand. The millivolt output from the thermopile energizes the operator in the valve on demand.

Q313 Thermopile Generator contains multiple thermocouples connected in series to increase the millivoltage output. The power generated is sufficient to operate an automatic millivolt gas control system, independent of any outside power source.
