12.2.2 Vent Restriction
WARNING: To avoid property damage or personal injury, allow
the fireplace ample time to cool before making any adjustments.
WARNING: Improper vent installation may cause the burner
flames to lift or “ghost.” Perform a visual check on flame
appearance after restrictor adjustment to ensure proper
performance.
Vertical terminations may display an active, compact flame.
To achieve desirable flame appearance, the vent exit may be
restricted by the restrictor plate (included in components packet).
This fireplace is shipped with the restrictor located in the fireplace
baffle set in the open position. Follow the tables below to adjust
the restrictor to desired flame appearance. Allow the fireplace
to burn for 15 minutes before making any adjustments to the
restrictor setting.
