INSTALL THE DAMPER

Once the Damper and the associated Broan or BEST exhaust

devices are installed, the installer should confirm that the Damper

opens and closes in conjunction with signals from the exhaust

devices(s) as intended.
A qualified HVAC contractor should also ensure the proper

operation and venting of all combustion equipment in the home.

SYSTEM OPERATION

Regular maintenance is necessary to ensure the proper operation

of the Damper system. Failure to conduct such routine maintenance

can jeopardize the ability of the Damper to introduce fresh air into the

home. Regular maintenance should include the following activities:
• Clean the outside bird screen to ensure it is free from debris and

open to allow fresh air to enter.

• Clean or replace the interior filter(s) which serve to filter fresh air

before it enters the home.

• Maintain a clear opening at the outdoor end cap, which means

preventing the buildup of snow, leaves, or vegetation at the end

cap.

• During regular HVAC maintenance, have the mechanical contrac-

tor inspect the Damper system for proper operation.

Install the damper as shown. Make sure damper flap is in a vertical

position when closed and power is off. The set screw can be used

to adjust the damper opening - thereby balancing the inside and

outside air pressure when the range hood exhausts at high speed.
