Unless the code have changed lately this is incorrect. Copper is not approved by code for natural gas and have not been for several years. LP gas however as far as I know of is still approved to be used surrounded by copper. The size of the line from reservoir to home may be too small but that can be rectified next to a second stage regulator at the home and run 10 pounds pressure from tank to house regulator inlet.

They wont mislead you and will give it to you straight. Now I'm speaking of the National fuel gas code. If your state have outlawed copper Id like to know and if you can find out, why.
