The PRV is located on the outside on all water heaters is standard safety with the same as a house HWH, it is the same PRV. Your saying because of the outlet being lower than the top there is an air bubble that in essence can never be purged. You do have to purge up to that point though otherwise you can crack the tank if turning on prematurely. The air bubble you speak of does not negate the need for the pressure relief valve. That is all I was trying to say.
Sorry for the confusion.... I should have been more clear on that.
