PENTAIR · 474953
400 ASME HD 9-Bolt Heat Exchanger Kit
Pentair 474953 is listed as the 400 ASME HD heat exchanger kit in the MasterTemp water-system replacement-parts table.
Compatibility and selection
The MasterTemp table places this HD kit in the new 9-bolt tub-design group dated November 16, 2013 onward. Verify the heater identification, HD specification and tub design before ordering.
What to check before replacement
The catalog separately identifies the standard 400 ASME kit as 474956. Do not select this HD kit solely by matching a 400 rating or assume interchangeability with an older assembly. The group lists the lid, nine nut/washer sets and silicone tube along with numbered assembly components. This is a replacement assembly, not a complete heater, fuel-conversion kit or blanket certification of the installed system.

Common ordering questions
How do I confirm the correct replacement?
The MasterTemp table places this HD kit in the new 9-bolt tub-design group dated November 16, 2013 onward. Verify the heater identification, HD specification and tub design before ordering.
Does the 400 rating alone establish compatibility?
No. Match the exact ASME and HD designation, heater model, manufacturing generation and 9-bolt tub design. The catalog identifies different kits for different assemblies; it does not make this kit universal.
