RESTRICTOR ADJUSTMENT
Adjust the restrictor to achieve the desired flame appearance on any top venting configuration with 6 ft (1.83 m)
of vertical pipe or more. Vertical terminations may display an active, compact flame. If this appearance is not
desirable, the restrictor may need to be adjusted. Allow 15 minutes of burn time before making any adjustments.
Adjust the restrictor as shown in this manual.
