I have a costumer inquiring about installation of two gas lanterns framing the entrance of their driveway. I was wondering if any one has any experience installing these? I imagine i would have to hire a licensed plumber to tap into the gas line, but after that could i do the rest of the installation? Is there a specific type of gas line used for direct burial to run to the lanterns? Where do you searched for rules and regulations for your state? Does anyone know of a website relating to gas installations? Any help would be greatly appreciated.
