Gas burners require a properly balanced mix of gas and air to burn efficiently. You can adjust the air intake by moving a plate or sleeve over an opening on the front end of each burner. To tell if this air shutter needs adjusting, look at the flame. A weak blue inner flame with a yellowish tip indicates too little air; a harsh blue inner flame, too much. A well-balanced flame has a distinct blue-green inner flame and an orange outer flame. The color may differ with bottled gas. Ask your technician to show you what a good flame looks like. To adjust the air intake, loosen the screw on the air shutter and gradually move the sleeve or plate to allow less or more air to enter. Newer burners with fixed shutters rarely need adjustment, if they do then hire a pro.
