To hook up a gas stove, place the appliance near the gas cock, wrap tape around the pipe threads, join the connector with the gas line, apply a street elbow, secure the connector nuts and check for leaks. The connector should be clearly marked for use with a gas range.
Begin by shutting off the gas cock, ensuring that the lever is pointed at a right angle from the pipe. Use Teflon pipe-joint tape to wrap the pipe threads twice in a clockwise direction, then wrap the unbeveled end of the end connector fitting in the same tape before screwing it to the gas line. A black gas line should never be connected to the nuts of a corrugated tube, as this can cause a leak.
Carefully screw a street elbow onto the gas port before screwing on the other end fitting of the connector. While securing the tube against the fitting, tighten the nuts on each of the two connector fittings. When the range is in place, the connector tube should not be kinked into sharp corners, which can eventually break. Lastly, spray a soapy water solution or a leak detector on the joints after turning the gas on and lighting the burners briefly. If the solution begins to bubble, the joint is leaking gas and must be adjusted.
