Hello, are there any references on suggested sequences of fittings to connect a capped 1 in. gas pipe (see the image) to a gas stove? This pipe is about 2 ft. tall, inside the wall, and hasn't been used for a while. What I have thought of was putting an elbow, 5 in. nipple and another elbow (all with 1 in. thread) to get the pipe outside the wall and U-turned downwards; then put a reducer bushing to switch to 1/2 in. thread for connection to the stove through gas ball valve, steel gas connector, flare fitting etc. Would this many fittings be acceptable or there are special fittings to minimize the number of joints? Would appreciate any suggestions. Thanks.

It also looks like that whoever hooks up the gas range has to break the drywall next to where the cap is to free some space for rotation of 1 in. elbow, because the pipe itself does not give in any direction.

If you remove the cross blocking, you will probably be able to move the pipe. Look at the floor notch. Then use a 1 >1/2" IP reducer, a 1/2 street ell and a 1/2"IP to flare fitting gas valve. Pipe dope or YELLOW Teflon tape on the 3 threads.

If this is a new range make sure you use the pressure regulater that comes packed with it. In this area after you are out of the wall in 1/2 pipe with value you can hook up to range with flexible stove connecter

Hi Harum
Whomever does this job should remove the 2"x4" that holds the pipe in place now, install the reducing 90 (1"x1/2") and then stub out of the wall with a short nipple and cap for now (until sheetrocked/drywalled). These fittings inside the wall should then be tested properly and inspected by a local plumbing/gas inspector. Remember to hang the pipe again after the reducing elbow, nipple and cap are installed.
I don't know of any states that require residential regulators anymore (as they are installed on the main gas supply before/after the gas meter) and I don't know of any stoves that send them with the new stove, but I suppose it should be checked... just in case!
Finally, of utmost importance after installation of the stove will be to install the ANTITIP device (see image) that is supplied with all gas stoves/ranges. These antitip devices save lives so do be sure to install it, OK?
Good luck!
