On a millivolt heater the valve also holds the circuit that the thermocouple energizes, which is why a failing valve can look like a pilot problem, a thermostat problem or an ignition problem depending on how it fails.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGetting the right one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eGas valves are specific to the fuel and the connection size. This is the natural gas valve at 1\/2 inch, and a propane heater needs its own part. Check the rating plate on the heater for both the model and the fuel before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReplacing a gas valve means breaking a live gas connection and leak testing the result. That is licensed work. Have a qualified gas technician fit it and verify the pilot, the safety circuit and the main burner before the heater goes back into service.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48627595870420,"sku":"RAY-151-3568","price":303.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_0b72d864-e7fa-4376-9cf0-26bd9d13c49e.jpg?v=1788724052","url":"https:\/\/www.activepoolsupply.com\/products\/1-2-natural-gas-combination-valve","provider":"Active Pool Supply","version":"1.0","type":"link"}
