1) Does this sounds good?
2) How long can I run flexible hose (I'm in Pennsylvania)
3) How do I disconnect an elbow to start the process?
I am new to plumbing...
Gas and threaded pipe is a lousy (difficult) place to start plumbing.
Gas pipe needs to be sized according to how many fixtures using what amount of gas are on the line. So what size is the line you want to tap off of, and what fixtures are already on it?
Given that you can tap off the line you have two options to get that elbow out.
The first is you need to to to the end of the line and un -thread everything before the elbow in order to unthread the elbow.
The other option is to cut the pipe with a sawzall Cut say 4" away from the elbow. This will allow you to remove that length. You then remove and re-thread pipe you sawzalled. Then get a left/right coupling and 4" left right nipple. One half of the coupling and one half of the nipple have reverse threads. Thread the pipe you cut back into place, then thread the coupling on the end of it. Now thread the tee onto the line you didn't cut. Now put the nipple between the tee and the coupling with the reverse threads pointing into the coupling. You can then make it up (be 100% sure both sides catch at the same time). Spinning it one way will tighten both ends.
You can not use flexible pipe unless you are certified to install it, you must use black threaded pipe.
Gas lines are usually a job best left for a professional plumber because of the inherent risk of working on a gas line, the risk of a leak causing injury, death, and/or property damage, liability and insurance issues, and the expense of proper equipment.
