Shipment of product and advice on what to buy was good. But when I received the product and called about the placement of the gas line as gas source was on left side and gas line on right side. I was told that most are made with gas connection on right side and I need to route a longer flexible gas line to the right side. I hired a plumber and the plumber took one look and reversed the gas connection so it can be hooked up to the left side. How could their tech guy not know this very basic fact.
