The water heater being grounded has nothing to do with the GFCI requirement. GFCI is for protecting people not equipment.

I get that. But the WH is permanently installed. No different than a cord connected dishwasher or garbage disposal. And it's UL listed and that listing covers the printed manufacture requirement for no GFCI/AFCI. In fact IMO, plugging it into a GFCI or AFCI is actually violating the listing.
By swapping out the receptacle to a single, we avoid convenient use by a homeowner. Not many people will intentionally unplug their water heater! BTW, that receptacle was for a former HW circulator pump.

The install manual for this UL listed product specifically says no GFCI or AFCI! What am I supposed to do?
BTW, this is my personal garage but this will be inspected as it's part of a California title 24 compliance.
I also think some of you are forgetting how a GFCI works and how it offers protection. It works by sensing a greater than 5ma of imbalance between hot and neutral. Such as using an un-grounded or defectively grounded metal power tool outside on wet ground or concrete. A properly grounded appliance does not need nor is benefited by an GFCI. A GFCI is for protection from faulty appliance grounds.

Buy a different manufacturers unit. I have been through this with some commercial units and there is no reason they can't build a better product. We use GFCI's on construction sites for all kinds of tools with very few problems.

True, but you are forgetting why NEC requires GFCI protection in certain locations. They took out exceptions several years ago for dedicated appliance receptacles partly because people were plugging in multioutlet adapters and such and using that non protected outlet for other uses anyway.
A water heater is not required to be GFCI protected. A 15/20 amp 120 volt receptacle in a garage is regardless of what it may be intended to supply. If you don't want to GFCI protect it hard wire it. If there is no fault in the appliance there should be no reason for the GFCI to trip in the first place.
