ADJUSTMENT
Burner Flame Adjustments
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
restriction adjustment to ensure proper performance.
Vertical terminations may display an active, compact flame. If
this appearance is not desirable, a restrictor plate may need to be
installed or modified after vent termination installation. Access to the
vent exit for restriction can be reached through the fireplace baffle.
