It is ASME rated, which is what most commercial specifications and inspectors ask for on a public pool. And the exchanger is the high performance, heavy duty cupro nickel build, which holds up better where water chemistry runs hard on plain copper. On a commercial pool that gets shocked, corrected and pushed harder than a home pool, that difference shows up in the service life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eControls and firing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eControl is digital with electronic ignition, so there is no standing pilot burning fuel between cycles and nothing to relight after a windy night. It is Low NOx rated, which matters in the regions that now require it on new gas installations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlanning the installation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe cabinet measures 23.02 inches wide, 32.61 inches deep and 28.15 inches high. Water connections are 2 inch, the gas connection is 3\/4 inch, and the heater is rated to 120 gpm of flow. Electrically it wants 120\/240 VAC, 60 Hz, single phase. Gas heater installation is licensed work, and a commercial ASME heater is not an install to attempt without one.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48646279725268,"sku":"PUR-15-0778","price":3427.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_bd4ed300-2138-44fc-ad2a-8ea8d0436cd3.png?v=1788987722","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-mastertemp-461020-digital-iid-heavy-duty-asme-natural-gas-low-nox-heater-250k-btu","provider":"Active Pool Supply","version":"1.0","type":"link"}
