Questions and answers

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

What is the difference between EC-462026 and 460732?
Both are Pentair's MasterTemp 250 for natural gas. Pentair keeps part numbers that begin with EC- for online sale and sells 460732 through dealers. This listing is EC-462026.
Where is the manual for the Pentair MasterTemp 250?
Under Downloads on this page, as the Owners Manual. It is Pentair's MasterTemp Installation and User's Guide, part number 472592, which covers the 175,000 to 400,000 BTU models in natural gas and propane, the HD and ASME versions included.
What do the ERR codes on a MasterTemp 250 mean?
Each one names the safety device that opened. ERR PS is the water pressure switch, which means no water is flowing through the heater. ERR HLS is the high limit switch, ERR AFS the air flow switch, ERR IGN a failed ignition and ERR SFS a stack flue temperature above 480 degrees F. What to check for each is in our pool heater error code guide.
Is EC-462026 the natural gas or the propane MasterTemp 250?
Natural gas. Pentair builds each MasterTemp 250 for one fuel, and the propane version is a separate part number.
Does the MasterTemp 250 have a pilot light?
No. It lights with a hot surface igniter on each call for heat, so there is no standing pilot to keep lit or relight.
