7.1 VENT RESTRICTION
7.2 PILOT BURNER ADJUSTMENT
Vertical terminations running longer than fi fteen feet may display a
very active fl ame. When this is not desirable, a vent restrictor could
be installed. This restrictor plate will reduce the velocity of the exhaust
gases, slowing down the fl ame pattern and creating a more traditional
appearance.
A. Remove the glass viewing door and logs.
B. Secure the restrictor plate as described.
C. Replace logs and viewing door.
Line up the holes on the vent restrictor with the holes on the bracket
attached to the roof of the fi rebox.
Secure the vent restrictor into position using the two screws supplied.
