PRIMARY AIR SHUTTER
BURNER FLAME ADJUSTMENT
The air shutter on the burner tube controls the primary com-
bustion 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. #13 for proper fl ame pattern.
Open primary air 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 pro-
ceeding.
To Adjust:
(See Fig. # 12)
1) Open and remove window frame and set aside. See
"Window Frame Removal" section found in the Installation
and Operating Instructions manual.
2) Remove the log set and set aside.
3) Loosen the screw in the Primary Air Shutter.
4) Rotate the shutter to increase or decrease the amount of
primary air.
Caution: Proper air shutter setting is a must.
The fl ame should be just orange and “lazy”. It should NEVER
be set to create sooting on internal parts and glass.
