ive done a few newer (<2 yr) old homes recently and have seen quite a bit of this CSST stuff. said houses will have a rigid black pipe main coming into the house and then CSST branch off to H20 tank and gas logs.
i cant seem to find any specific requirements for proper installations. (ie, size, length, how to properly secure, which appliances can use it, etc…) can anyone point me in the right direction? is this something that is different per city?
