Water Heaters - Moving Gas Hot Water Heater

I recently converted to gas and have a new 50 gallon HWT. The tank is located in a utility room that appears to have been an old carport at one time (i.e. sitting on a foam pad, approx 2 inches thick sitting on concrete.)

I wish to remodel this room with the end result being a framed sub floor sitting on top of this old concrete pad and I need to move the HWT. Two questions.

One - the tank currently vents directly out the roof via vent pipe. Does this vent pipe have to be completely verticle, or can it angle? I'd rather not have to cut a new hole in my roof to move the vent pipe three feet.

Two - I have read other threads here about moving HWT's and this doesn't appear to be rocket science. Turn off gas at tank, turn off power, drain, and disconnect and move. Is that basically it, or am I over simplifying?

You can use 45 degree fittings in the vent however they have to keep a vertical rise. No 90 degree fittings are permissable. You seem to have the installation down pretty good. I would still check with local code office to make sure you are doing everything to code. Phone call is cheaper than tearing it back out or causing injury to family members. Good luck.

Thanks for the venting information - I plan to check everything out with the local code guys prior to doing anything crazy.

Thats always the best idea. Aside from the fact that codes are there for a reason, it's easier to do it right the first time.
