It is model B-R207A-EN-X, Raypak part 017709.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the ASME rating is for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eASME certification is a construction and inspection standard for the pressure vessel inside the heater. Commercial, municipal and institutional pools are frequently required to run an ASME rated heater, and no amount of residential equipment will pass that inspection. If the specification calls for ASME, it is not a preference.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCupro-nickel and bronze\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe exchanger and headers are where a pool heater dies. Copper and cast iron do fine on well balanced residential water, but low pH, high sanitizer and heavy bather load eat them. Cupro-nickel tubes with bronze headers are the combination specified when the water or the duty is harder than average, which is the usual reason to buy this build rather than the standard one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is a natural gas appliance.
