The gas pipe for the stove is 4 inchs away from the wall. The stove is also sticking out 4 inches. I went in the crawl and looked it looks like if I loosen the holding brackets and move it a bit I can get it done with out having to run new pipe.

I thought move it with out applying any pressure or stress drill a new hole and remount the holding brackets or clamps which are nailed in to the top of crawl. It seems simple if I have to get a plumber to do it I'll have to pay perhaps for something I could do myself.

I thought give it a try and be gentle and see if it will work before I hire someone. If I need to modify I'm for sure going to get someone. I don't see any harm in seeing if I can just adjust the angle a bit and re do the supports. The run is about 20 feet and the pipe seems like it has a fair amount of play to adjust the little I need to make it right.

You know it being a gas line I want to be sure before I proceed. Was looking for input. I don't know is there a code that you need to be licensed when working with gas lines. It does look like it would not be much to make the adjustment and drill the hole and move the stove back and connect to the stove.

Gas has the potential to cause serious injury and damage. Be very careful trying to bend a black iron gas pipe 4" although a 20 ft. piece does have some flex. You need to be very sure you are not loosening a fitting or cracking a nipple. An approved way would to go back to a connection fitting, install a 45 degree street ell, a 3 1/2" nipple and another 45 degree straight ell and continue with the old pipe. Pipe dope everything and test for leaks after installation. This would bring the up nipple to the wall and a new hole could then be cut in the floor. DO NOT ATTEMPT THIS IF YOU ARE UNSURE HOW TO DO OR IF YOUR LOCAL GOV'T REQUIRES A PERMIT!! Where is the shut off valve for the stove?

When it comes to rigid gas piping, offset fittings (90s, 45s) are really the only way to go. As ma0641 suggested, there is some give in a 20 footer, but putting any stress at all on it could cause the threads to crack/leak. A couple 90s and a three inch nipple should get you where you need to be, but you will have to test the system. May be best to hire this done. Shouldn't take a plumber, gas fitter to long, and will let you sleep better at night. Overall, gas is the last job for a do it yourselfer, as it is one of the most potentially deadly systems in the home if not done correctly. I wish I could walk you through this, but I need to be able to sleep at night too ;). Good luck and I hope all turns out well for you.
