The size sets how much fuel reaches the flame, which is why orifices are matched to both the fuel type and the heater size. Damaged, corroded or previously drilled orifices upset that metering and show up as poor flame, sooting or a heater that will not hold its temperature rise.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch the fuel\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the natural gas kit. Hayward supplies a separate part for propane, so check the rating plate on the heater before ordering. Orifice replacement and any fuel conversion is work for a licensed gas technician, who can verify manifold pressure and combustion once the kit is fitted.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634388709588,"sku":"HAY-151-0017","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_af3aea93-bfa1-447b-8c8a-f51d78278f34.jpg?v=1788829014","url":"https:\/\/www.activepoolsupply.com\/products\/natural-gas-burner-orifice-kit-fd","provider":"Active Pool Supply","version":"1.0","type":"link"}
