My gas stove is falling apart. I found basically the same gas oven used, but a few years newer than my current stove. I am going to pick it up tomorrow. I was wondering if it would be all right for me to hook up the gas line. Is it as simple as turning off the gas line, unscrewing the hose and screwing it back onto the new stove? Or do I need to have PSEG (the gas company) come hook it up?
