Lew, check with your local building code. I had a gas stove put in my kitchen with a new gas line, well, an illegal fitting was used for the connection, no sealant was used and to boot, it was only on hand tight. When I had a gas fireplace installed in the basement, the gas fitter pointed this all out to me. The store shose service I used originally was out of business by then, good riddance, people like that don't deserve their jobs. As a former firefighter, you know not to mess with natural gas and propane. Look into it to make sure.
