It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe cover closes the top of the burner chamber. If it is warped, cracked or corroded, combustion gases can escape and the airflow through the burner is disturbed, which shows up as poor ignition, soot or a heater that runs rough. Replacing the cover restores the seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the 125 size cover only; larger MasterTemp and Max-E-Therm heaters use different parts. Check the build date on the heater rating plate and count the lid bolts. Nine bolts and a date after 11\/16\/13 confirms the match. Gaskets are not included and are available as a separate Pentair kit.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625021354196,"sku":"PUR-151-4441","price":428.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/pentair_474958.jpg?v=1788662450","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-474958-combustion-chamber-cover-for-max-e-therm-heater","provider":"Active Pool Supply","version":"1.0","type":"link"}
