Does a Navian Water heater 120 volt Gas type. Need to be GFCI I have only a Arc fault in stock. Arc faults are mandatory in Residential I believe now.

But I don't have any combination Arc/gfci in stock. Need to finish.
 
Where is the heater located. The basement crawl space, closet etc.

Is this tankless? Most tank water heaters don't need electrical power.
 
The location and if it’s plugged in determines if it needs GFCI. My Navion tankless gas uses 120V for the controls
 
If the water heater has a spark igniter it might trip an AFCI or AFCI/GFCI breaker.
Good point but as Tom stated the protection is based on the location of the receptacle. What do you do if the room requires AFCI and GFCI protection? I'm thinking that these new units will still work fine. My tankless HWH is plugged into a GFCI receptacle with no issues. You might be on to something with AFCI protection.
 
I have seen very few gas tank water heaters that did need power. Some needed power to accessory motors but most don't need it--at least around here.
Same here if it uses a chimney for the exhaust flue connection and doesn't a have a power vent.

I was assuming we were talking tankless since the OP said it was 120V. When you said tank, I went to electric in my mind. That's why I said I never saw a tank heater that didn't need power. I guess our thoughts were going in different directions.
 
Looks like the moderator's are having a haha moment. :)
If this unit has a cord cap to plug into a receptacle, then it's subject to location requiring GFI
