Is there a CODE that states where the street side main gas turn off should be located within the home?? I could not find anything about location. My situation is that we want to put our manifold on the middle wall of basement to save on the length of our CSST runs. The 1” line enters the sill plate, runs 19’ through a bay and then elbows down to a shut off valve, then tees into the manifold. Should there be a shut off installed between the first length of pipe running inside the bay?
