BURNER ADJUSTMENTS

BURNER ADJUSTMENTS

When using 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 and the air shutter needs to be opened up. In the event this does not solve the situation, check the burner for obstructions and clear as necessary. If the flame is lifting off the burner, there is too much primary air and the air shutter needs to be closed down (Diagram #5).

If grates, hot tops or oven bottoms have been removed, be sure to recheck flame adjustments with these items in place as the flame characteristics may change and additional adjustments may be necessary. Always recheck burner flames after the grates, hot tops and oven bottoms are in their proper place.
