Damper Adjustment
The Casco and Camden fireplaces both come with an adjustable damper that can limit the flow of
intake air. This damper is located behind the air deflector at the rear of the inner firebox. Sometimes
on installations that involve vertical venting configurations over 10 feet in height, the intake air tends
to accelerate down the vent causing hectic flame action. This damper can be closed partially to
reduce the speed of the intake air and thus calm the flames to a more natural look. Over-closure of
this damper could cause an insufficient air supply to the fire, which would result in flames that cause
soot. See “Damper Position” on page 19 for optimum damper position.
To adjust the damper, loosen the two screws that hold the air deflector in place. Slide the damper
down to a position that will reduce the air speed entering the appliance, using the bend tab at the
bottom edge of the damper. This might take a few adjustments to obtain the best flame appearance.
Because removal of the media, burner and burner tray are necessary for damper adjustment, you
may put the burner and tray in place without fastening the screws to test the intake airflow. Once the
damper is fastened in its adjusted position, return the burner and tray into place and fasten with the
appropriate screws. Position the media as instructed in this manual.
