This appliance has an air shutter that
has been factory set open according
to the chart below:
Closing the air shutter will cause a
more yellow fl ame, but can lead to carboning. Opening
the air shutter will cause a more blue fl ame, but can cause
fl ame lifting from the burner ports. The fl ame may not ap-
pear yellow immediately; allow 15 to 30 minutes for the fi nal fl ame color to be established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED INSTALLER!
Access plate and gasket must be re-installed after adjustment.
The alternate access is to remove the glass media, media tray and burner from the appliance and then adjust the
air shutter.
NOTE: When removing the media tray make sure the glass media are away from the center of
the screen, exposing the burner, before lifting media tray out.
When replacing burner, absolutely no glass can be in cup surrounding the orifi ce.
HINT:
If glass falls into cup and
surrounds the orifi ce, insert a clean bag into a vacuum cleaner and vacuum out glass media. Replacement glass
media can be ordered from Wolf Steel Ltd.
