As long as the flame is present, the thermocouple stays hot and produces voltage, which tells the gas valve that it is safe to allow gas to flow. If the flame goes out, the thermocouple cools quickly, the voltage drops, and the gas control valve shuts off the gas supply to prevent unburnt gas escaping — a crucial safety function on natural gas appliances.\u003c\/p\u003e\n\u003ch3 data-start=\"833\" data-end=\"855\"\u003eUniversal Design\u003c\/h3\u003e\n\u003cp data-start=\"856\" data-end=\"1165\"\u003eBeing \u003cstrong data-start=\"862\" data-end=\"875\"\u003euniversal\u003c\/strong\u003e means this thermocouple is made to fit a wide range of natural gas appliances rather than a single specific model.
