Natural gas burns cleanly. When combusted, it creates heat, but no carbon monoxide, soot, or other contaminants to the air we breathe. Even so, be sure that gas appliances have adequate ventilation--there should be air vents both in the ceiling and the floor of the area where gas appliances are located.

This is the main gas line. Modern gas lines have a length of flexible pipe connecting the main gas line to the appliance. The gas is turned off when the handle on the main gas line is perpendicular to the pipe. A one-quarter turn (90 degrees) of the faucet handle makes it parallel to the pipe opens the gas line to the appliance. There's usually only one way to turn the handle. Look at the control knob on the unit. Usually it's a round knob with lettering that indicates three positions: off, pilot, and on. These three settings are critical to our operation. A marker arrow should be located somewhere next to the knob on the appliance itself. This marker indicates which setting you've selected on the knob. Locate the pilot light fixture. It's usually a small metal pipe that originates at the gas line and is located next to the burner unit. Sometimes it looks like metal cylinders, with a small pipe that looks something like a candle wick. It's usually located on the right side of the burner as you'e looking at it from the front. If you're lucky, it may even be labeled. Notice that you'll have access to the pilot light fixture either from the wall of the appliance (through a hole or removable panel), or by reaching up from the bottom. Sometimes there'll be just enough access to put in a match held with your fingertips. Have your equipment handy. Flashlight, matches, and wrench should all be within easy reach. Having another person around to assist is a great idea. Step 4
