The Q390A thermocouples sense the pilot flame on standing pilot gas-fired heating systems. The pilot flame heats the tip of the thermocouple, producing a temperature differential between it and the base to generate 30 millivolts. Push-in clip, split nut, or adapter assembly available (depending on model) for easy pilot burner installation.
