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.

Moving the shutter bolt to the right closes the air shutter. Moving the shutter bolt to the left, will open the air shutter.

Opening the air shutter causes flames to become shorter and blue. Closing the air shutter creates taller orange/ yellow flames.

After adjustment, tighten wing nut to lock in place.

Note: Do not close so much as to cause a sooty flame. Improper adjustment can cause sooting in the firebox and/or on the outside of a house with a horizontal termination.
