The heat exchanger on this model is listed as copper. Electronic ignition removes the standing pilot, so the heater is not burning gas between cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRead this before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eASME model MasterTemp heaters do not come with tubes and unions, and those parts are no longer available to buy separately. That makes this the right heater only if you are replacing a previous Pentair ASME unit and already have the hookups in place. If you are not certain, check what is on the pad before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA gas heater of this size needs a correctly sized gas line, proper venting and a qualified installer.
