The air shutter on the burner tube controls the primary combustion air to the gas burner
and is preset 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. #29 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.
