Installation
STEP 10
Install Damper
• Position the damper over the damper adapter and secure using the screws provided.
STEP 11
Connect Ductwork
• Attach ductwork to damper. Secure the ductwork with duct tape to make joints are secure and air- tight.
• Do not install the duct tape too tightly as this may prevent the damper aps from opening which will overwork the motor
and cause improper functioning of the unit.
• Fasten all connections with sheet metal screws and tape all joints with certied aluminum or foil tape. Use caulking to
seal exterior wall or roof opening around the cap.
