Bronze headers and an ASME-certified copper fin-tube heat exchanger take the place of the polymer headers used on the residential model, for pools and spas where an ASME heater is required, typically commercial sites. Item 017372 is the natural gas, copper version for sea level to 2,000 ft.\u003c\/p\u003e\n\u003cp\u003e✅ \u003cstrong\u003eMade for:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFuel: natural gas only.
