Hello All, I need a little help in finding out about allowable fitting location on gas piping. I looked in the NFPA54 book and could not find what I needed.
I have a job that has a union in the middle of a gas pipe in crawl space . I know you need a union near an appliance (after the service valve) to connect it. I remember reading that a union cannot be installed in the middle of a gas pipe accessible or not. I'm looking for the wording in the Fuel gas code but I'm not having any luck. Does anyone know what chapter or section I need to look for this information?
Thanks in advance.
