Flame Appearance -

Air Shutter Adjustment

WARNING: AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.

The air shutter setting at the burner orifice can be adjusted to achieve the desired flame appearance. The shutter is set in the mid-range at the factory, however, you will want to adjust it if a fuel conversion kit has been installed or if the flame pattern is not as desired. The adjustment stem is located under the firebox, directly behind the gas control valve. Generally, flame appearance is a matter of preference, however most people enjoy a warm yellowish flame.

Too much air - the appliance will generate a flame that is blue and transparent, or an “anemic” flame.

Not enough air - the burner will generate very long yellow flames resulting in soot. Sooting produces black deposits on the logs, on the inside walls of the appliance, and potentially on the exterior termination cap.

Sooting is caused by incomplete combustion in the flames and lack of combustion air entering the air shutter opening. Open the shutter setting to allow more air.

To adjust the air shutter:

1.Locate and loosen the adjustment stem wingnut protruding from the bottom of the firebox, directly behind the gas valve. See fig. 26.

2.Push the stem back to decrease air, or pull it forward to increase air. Make adjustments in small increments (1/8”) and allow the burner to “ settle in” for a few minutes before making another one. Small shutter adjustments can produce dramatic changes to flame characteristics.

4.Re-tighten the wing nut when the desired flame appearance has been achieved.
