Thermocouples generate a small millivolt signal from the heat of a pilot flame, holding open a gas valve safety seat. This unit ships with the necessary fitting for connection to a standard gas valve port, making it a direct service replacement for technicians working on residential and light commercial heating equipment.\u003c\/p\u003e\u003cp\u003eThis thermocouple is suited for gas furnaces, boilers, water heaters, and other standing-pilot gas appliances that rely on millivolt-based flame safety circuits. The 30-inch lead length provides enough reach to route cleanly from the pilot assembly to the gas valve in typical cabinet configurations, reducing the need for extensions or adapters during service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-inch lead length accommodates standard pilot-to-valve routing in residential and light commercial equipment\u003c\/li\u003e\n\u003cli\u003eIncludes fitting for direct connection to gas valve thermocouple port\u003c\/li\u003e\n\u003cli\u003eMillivolt output holds gas valve safety seat open during normal pilot operation\u003c\/li\u003e\n\u003cli\u003eService replacement design for standing-pilot gas appliance systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a service replacement thermocouple for standing-pilot gas appliances including furnaces, boilers, and water heaters that accept a standard threaded thermocouple fitting at the gas valve.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed gas technician or qualified HVAC-R service professional in accordance with local codes and the appliance manufacturer instructions. Always shut off the gas supply and allow the appliance to cool before removing the existing thermocouple. Hand-tighten the fitting at the gas valve, then snug with a wrench — do not overtighten, as thermocouple fittings are brass and can be damaged. After installation, verify pilot flame engulfs the thermocouple tip fully and that the gas valve holds before returning the appliance to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Length\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting\u003c\/strong\u003e: Included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HEATCONTROLLERMARS72230\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MARS-72230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HEAT CONTROLLER","offers":[{"title":"Default Title","offer_id":51524842815794,"sku":"MARS-72230","price":31.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72230.jpg?v=1785459333","url":"https:\/\/voomisupply.com\/products\/heatcontrollermars72230-mars-72230-thermocouple-30-in","provider":"Voomi Supply","version":"1.0","type":"link"}
