The source lists its input as 336,000 BTU in the model description and 333,000 BTU in the product copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the ASME build\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eASME construction is what commercial pools and many public and municipal installations are required to use. It is a heavier specification than a standard residential heater, matched here with a digital control set and intermittent ignition rather than a standing pilot.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBronze and cupro-nickel\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe header is bronze and the heat exchanger is cupro-nickel. That pairing is chosen for water that is aggressive: heavily chlorinated pools and salt systems both shorten the life of a plain copper exchanger, and this combination is built to last in those conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProTek Shield\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRaypak adds a ProTek Shield module that is designed to absorb the corrosion that would otherwise reach the heat exchanger. It is meant to erode: visible wear on the shield is a sign the protection is working, and the module is built to be swapped out without major disassembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the 0 to 2000 ft elevation natural gas version. The source also references a related model, C-R336A-EN-X, part 010200, so order by the model number on your specification rather than by BTU alone.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48625785176276,"sku":"BR336AENX","price":5002.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7797bdad-b962-41bc-bb3a-43c3ae38a6e7.png?v=1788692329","url":"https:\/\/www.activepoolsupply.com\/products\/raypak-heater-336k-btu-natural-gas-asme-digital-iid-bronze-header-cupro-nickel-heat-exchanger-b-r336a-en-x","provider":"Active Pool Supply","version":"1.0","type":"link"}
