The Maid O Mist 48” Replacement Thermocouple is for gas furnaces, boilers and water heaters that operate on 30 millivolt systems. Our 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.
These replace products that include push-in, clamp-in and screw-in burners. This item is very durable and made from heavy gauge copper and the connections are thick gauge steel. This item will provide maximum durability. The installation is simple and includes positive positioning features.
