The air shutter on the burner tube controls the primary combustion air. It is set to the closed position at the
factory for natural gas fuel. For liquid propane, See “Propane Conversion” on page 13. Some adjustment
may be necessary to obtain desired flame and to eliminate carbon deposits. Evaluate flame appearance after
the fireplace has reached operating temperature. See Figure 29 for proper flame pattern.
Open primary air if the window glass and firebox have carbon accumulation and/or the flames are long, dark
and stringy. The shutter may also be opened to lessen the flame height.
Burner Flame Adjustment
NOTE:
Proper air shutter setting is required.
The flame should be just orange and “lazy”. It should NEVER be set to create sooting on internal parts
and window glass. Allow the fireplace to run for 30 minutes before evaluating flame appearance.
