This kit is designed specifically for the Model 300 output rating and is not interchangeable with conversion kits for other MasterTemp output models. Have a licensed gas technician verify the gas supply pressure and regulator compatibility for LP operation before the conversion is performed.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-03 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53912384897299,"sku":"460755","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN460755_0.jpg?v=1772793849","url":"https:\/\/poolaroo.com\/products\/pentair_460755","provider":"Poolaroo","version":"1.0","type":"link"}
