The air shutter on the burner tube controls the primary combustion air to the gas burner and
is pre-set closed at the factory for natural gas fuel. Some adjustment may be necessary to
obtain desired fl ame and to eliminate carbon deposits. Evaluate fl ame appearance after the
fi replace has reached operating temperature. See Fig. #17 for proper fl ame pattern.
Open primary air shutter if the logs, glass, and fi rebox have carbon accumulation and / or
the fl ames are long, dark and stringy. The shutter may also be opened to enhance the Ember
Material glow and lessen the fl ame height.
Caution: Burner area may be hot!
Turn off the fi replace and allow the unit to cool before proceeding.
