Gas Heater

If you are going to have a gas heater to your pool or spa you need to include special information for the permit and you also need a special inspection.

I wasn't home when they dug the hole, I wonder how the machine looked like that made that kind of hole. The gas line have to be buried deeper than the electric lines and the plumbing.
Make sure before you get your permit where you going to have the heater. If you like to change some gas lines it counts as a change of plane and you have to fill in more paper, get an additional permit and it will cost you some extra dollars.
