Sump pump gfi protecting water heater power vent

I'm in Pennsylvania, where we have adopted a "statewide" code. (sarcasm intended)
Anyway, per builders' specs, we have been installing a gfi recep for the sump pump, and protecting the power vent on the water heater with that gfi. Now, after a long time of working in this development, we failed inspection because of it.
Is this a recent change or something the inspector just discovered in the code book?
Thanx.

I'd bet that he doesn't want that power vent for a fossil fueled appliance on a GFCI that's powering a sump pump.

Code reference or would this be in the manufacturer's instructions?
If I were researching that issue I'd start with the fuel gas code, then mechanical code, etc.

Of course having a model number to view the installation manual would be quicker.

OP: can we get a model # for this appliance?

I did a little digging online and it seems some installation manufacturers want dedicated non-GFCI branch circuit and others are arguing the NEC requires the GFCI in an unfinished basement. But aren't dedicated circuits exempt? Or are they?

Almost all the exemptions have been removed.

Under the current NEC the sump pump would not be exempt from the GFCI requirements in unfinished basements.

My feelings - no code violation unless instructions of either appliance call for dedicated circuit, but that may not be too likely.

But absence of hot water is a good indicator that the sump pump probably doesn't have power as well.

If you don't want GFCI protection on either of those appliances then you either need to direct wire them (if they have that option), or place them in an area that doesn't require GFCI protection for receptacles that are in that area.

OP Here
The pump instructions say nothing about requiring its own circuit, and neither does the power vent.
If his was the first house we did for this inspector, I wouldn't have an issue. Same inspector, new requirement. This is what I hate most about my job anymore. The inconsistencies by the inspectors. Not just agencies, but the same inspector. I have a call in for him for the code reference but I haven't heard back yet.

Yep, I would just pick up that sump pump and put it in another room, probably dryer in there too and it shouldn't run as much!:p

I think the concern on the table here is the power vent on the fossil fuel burning appliance. CO will kill and it happens.

Can we get a model number on the power vent?

IIRC, when I installed a dedicated circuit for my clothes washer and put it on a GFCI breaker, the inspector said that because it was a dedicated circuit I needn't have bothered with the GFCI, but this was back in 2006 in NJ; don't know if it's changed since.

As Iwire stated most exceptions allowed under 2005 and earlier codes are gone.
