This company tells you they will do an installation one way, and then actually do it another. I had a propane tank and gas line installed at my home. A gas range was also to be connected. The inside installation was such that my gas range could not be pushed back against the back wall and stuck out so far that a kitchen drawer would not open properly. The outside installation was also totally unacceptable and was not up to code. I had to bring in a licensed plumber to correct their mess and fix the outside properly and professionally.
