K. Air Shutter Adjustment
The air shutter is used to fine-tune the flame as necessary.
The air shutter is shipped in the fully open position.
Allow the unit to operate 15-20 minutes before making any
adjustments to the air shutter. This will give the flame time
to reach its height and color before making adjustments.
The air shutter control bolt adjusts the amount of air that
mixes with the gas as it enters the burner pan.
To adjust the air shutter, remove the screw from the control
panel
.
Rotate forward and lift off.
