Both fi replace models have air shutters that have been factory set
open according to the chart below:
These settings are for (maximum) horizontal termination. Adjust-
ment may be required depending on fuel type, vent confi guration
and altitude.
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
appear yellow immediately; allow 15 to 30 minutes for the fi nal fl ame
colour to be established.
Air shutter adjustment must only be done by a qualifi ed
installer!
The alternate access is to remove the glass, glass ember tray and
burner from the fi replace and then adjust the air shutter.
The front of the fi replace becomes very hot during operation.
Let the fi replace cool completely before conducting service.
NOTE: When removing the glass ember tray make sure the glass
embers are away from the center of the screen, exposing the burner,
before lifting glass ember 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 embers or
replacement glass embers can be ordered from Wolf Steel Ltd.
