Air Shutter Adjustment

The efficiency of the burners depends upon a delicate balance between the air supply and the volume of gas. When this balance is disturbed, poor operating characteristics and excessive gas consumption will occur.

An air shutter on the front of each burner controls the air-gas mixture. With natural gas, the air shutter will be approximately 50% open. On propane (LP) the air shutter will be approximately 90% open.

If the flame is soft, lazy, or yellow:

There is not enough primary air. To correct this condition:

1.Rotate the air shutter open until the burner flame begins to lift from the burner, then close the shutter slightly.
