The Bristol and Bedford 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.
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.
