I just finished installing a new GAS water heater in my garage. I am wondering if it matters if it is right up against the wall.
It's sitting on a stand (18" requirement) to keep it off the floor. I also have two earthquake straps holding it in place. I finished hooking everything up and soldering my pipe for the overflow drain (it runs into a wall and then outside) and then I went to put on some insulation and I realized I didn't leave any space at the back of the water heater. I can't even get my hand between water heater and the wall.
It's right up against the wall. I can't for the life of me remember if the old one was also that close but I'm wondering if it's safe to have it that close or if I need to drain it and try to shove it out 1-2" away from the wall. Because it's on the stand I can probably only move it 1" away or so.
I was trying to figure out if it will be possible to move it with everything attached because I hate to have to unhook everything. It's got the flexible tubing pipes at the top and the copper drain pipe has at least 1" of give to it. The vent at the top might be the only tricky part.
Not sure if anyone knows if there needs to be a gap between the wall and the gas water heater, I do know I didn't move the stand at all and it was right up against the wall with the last water heater.
On the plus side the new one is working beautifully.
Thank you for the help.
