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.

Questions and answers

What people ask about this product, answered by our pool techs.

Does this heater come with tubes and unions?
No. The ASME MasterTemp models do not include them and Pentair no longer sells them. Only order this model if you already have the hookups from your previous Pentair ASME heater.
What fuel does it run on?
Natural gas. The propane version is a different Pentair part number.
Why choose the ASME model?
ASME rating is what commercial and many public installations require. Check your local code and inspection requirements before choosing between ASME and the standard model.
What heat exchanger does it have?
Copper, as listed by the manufacturer for this model. Pentair builds other MasterTemp variants with a cupro nickel exchanger under different part numbers.
