You need to see the local LPG supplier as they have regulations that have to be met before they will fill your tank. They'll give you a free copy. If there's no local building codes then your done but you do have to meet local codes as well if any.

NO code allows for burried CU pipe. Why? We just had a good expalnation two weeks ago. A appartment owner decided to install a "no parking " sign but failed to follow codes when installing his gas line. You got, it he drove the sign stake right thru the gas pipe. Theres no longer a 8-plex standing there as it burnt them down.

Code calls for machine wraped steel pipe with 300mil wraped joints, can be black or galvanized pipe. The reason for this all soil has nitric acid in it and it will eat thru the pipe in a few years. Pipe run has to be pressure tested at 10psi for 20 minutes without ANY pressure loss and the testing gauge has to read 0 to 20psi in 1psi incraments.

Too many codes to list here for a "internet install" but it's not that costly to meet gas codes rather than mickey mouse the piping in.

Remember Your dealing with your familys life and you better get it correct the first time as sometimes there's no second chance.

I never consider a comments arguring. For as long as I can remember soft CU can't be used underground gas but can be used for tank to main line or shut off to appliance at one time. Here now they require a approved UL rated flex and gas valve at the appliance. I know about 1990 or so they changed underground to include galvanized pipe as they changed the way the galvanize was applied to the pipe so it didn't flake off inside the pipe.

You got my interest on the CU install tho so I'll do some more checking. I'm not keeping up with all the code changes like I used too. I've never seen a supplier make that kind of mistake so it must be approved.
