Dear Andrew;
There are screwed joints in this piping system that is buried in the walls and ceiling since 1920. Is this a correct statement? You will have to hire a certified gas contractor , who is familiar with local codes.

He may have to repipe the gasline using copper tubing or stainless steel tubing like “Tracpipe” (niffty stuff) only joints are at either end.

Best regards An old gasfitter,
