Product details
The Pentair MasterTemp 460775 is the 400,000 BTU natural gas commercial pool heater in ASME configuration, with electronic ignition, Low NOx operation and a digital temperature control.
Commercial output
At 400,000 BTU this is full commercial capacity, sized for large volumes of water and for the short recovery times a commercial schedule demands. 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.
Read this before you order
ASME 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.
Installation
A gas heater of this size needs a correctly sized gas line, proper venting and a qualified installer. Confirm those before the heater arrives, since it ships by freight.
