{"product_id":"121-712","title":"121-712","description":"The Mercury Flame Sensor is a critical safety component designed for high-performance heating systems and gas-fired appliances. This precision-engineered sensor rod acts as a primary flame verification tool, ensuring that the burner has successfully ignited before allowing the gas valve to remain open. By detecting the heat generated by the pilot or burner flame, it provides the necessary signal to maintain system operation; if no flame is detected, it triggers an immediate safety shutdown to prevent the accumulation of unburned gas. Ideal for HVAC technicians and property owners, this replacement part resolves common furnace issues such as short-cycling, ignition failure, or burners that extinguish shortly after lighting. Built to withstand extreme temperatures, it ensures the reliable and efficient operation of your commercial or residential heating equipment.\u003cbr\u003e\nType: Flame Sensor Rods\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used primarily in gas furnaces, commercial heating units, and industrial HVAC systems as a safety flame-proving device.\u003cbr\u003e\nSpecifications: High-temperature resistant construction, mercury-actuated switching for reliable flame detection, designed for direct integration with gas control valves.","brand":"BCFurnace","offers":[{"title":"SENSOR,FLAME MERCURY \/ 121-712","offer_id":50217108504861,"sku":null,"price":1587.39,"currency_code":"CAD","in_stock":true},{"title":"SENSOR,FLAME MERCURY \/ S1-3098-156","offer_id":50217108537629,"sku":null,"price":1587.39,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/121-712","provider":"BCFurnace","version":"1.0","type":"link"}
