Raypak lists it for the 206A, 266A and 336A pool heaters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat refractory does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRefractory is the insulating wall that stands between the burner flame and the rest of the heater. It holds heat where it belongs, in the combustion chamber and against the heat exchanger, and it keeps that heat off the cabinet and the components around it. Every time the heater fires, the refractory takes the full swing from cold to combustion temperature and back.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThat heat cycling is what eventually breaks it up. Crumbling edges, cracks running through a panel, or pieces sitting loose in the bottom of the chamber all mean the refractory is no longer doing its job. Left alone, a heater running with broken refractory puts heat into places that were never meant to see it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChecking the fit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe panels measure 17 in high, 14-1\/4 in wide and 1 in thick, so you can measure what you pull out. The parts diagram this refractory appears on covers the 206A, 266A, 336A and 406A, while the part listing itself calls out the 206A, 266A and 336A. Match part number 010088F to your heater before ordering.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48625748017364,"sku":"RAY-151-0088","price":199.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_afe92119-c69f-4f35-97f0-33f49a8fba4a.jpg?v=1788691482","url":"https:\/\/www.activepoolsupply.com\/products\/refractory-common-left-right-both-sides","provider":"Active Pool Supply","version":"1.0","type":"link"}
