It is the genuine Pentair part, printed on the valve as 073998.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNatural gas only\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eGas valves are fuel specific. This one is for natural gas. If the heater runs on propane, or has been converted, the valve is a different part number and this one is not a substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich heaters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOur source material does not agree with itself on the model range. One reference lists the valve for MiniMax heaters 120 through 400, another files it under MiniMax Plus 150 through 400. Both point at the same family of heaters, but the safe move is to read the model number and BTU rating off the data plate on your heater and check it against the Pentair parts breakdown for that exact model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOn an intermittent ignition heater, the gas valve is what opens on a call for heat once the control has proved the ignition sequence. When a heater sparks but never lights, or lights and drops out, the valve is on the short list of causes along with the igniter, the pressure switches and the control board. Changing it means breaking a gas union and leak testing the joint afterwards, which is licensed work in most places. Have a qualified gas technician do the swap.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628957020372,"sku":"PUR-151-4903","price":289.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_a85762f4-e866-495f-ab8c-350337e20b89.jpg?v=1788758489","url":"https:\/\/www.activepoolsupply.com\/products\/natural-gas-valve-iid","provider":"Active Pool Supply","version":"1.0","type":"link"}
