I have a GE Power Vent, Model GG50T06PVT natural gas water heater. I plan on going on vacation for two to three weeks and I will shut the water off to the house at the main shutoff. I also plan to turn the power off to my GE natural gas water heater.

Thus, my question is: Will shutting off the water and electric to my natural gas water heater for two to three weeks cause any potential issues? Also, will I have any potential issues upon returning from vacation and turning the water and electric back on to the water heater?

Thanx
