Damper/Air Shutter - Pacific energy BRISTOL Installation And Operating Instructions Manual

The Bristol and Bedford replaces both come with an adjustable damper that can limit the ow of intake air.
This damper is located behind the air de ector at the rear of the inner rebox. Sometimes on installations that
involve vertical venting con gurations over 10 feet in height, the intake air tends to accelerate down the vent
causing hectic ame action. This damper can be closed partially to reduce the speed of the intake air and
thus calm the ames to a more natural look. Over-closure of this damper could cause an insufficient air supply
to the re, which would result in ames that cause soot.
To adjust the damper, loosen the two screws that hold the air de ector 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 ame 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 air ow. 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.
