STEP 12
Connect Ductwork
•
Attach ductwork to damper. Secure the ductwork with duct tape to make sure joints are secure and air- tight.
•
Do not install the duct tape too tightly as this may prevent the damper flaps 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 certified aluminum or foil tape. Use caulking to
seal exterior wall or roof opening around the cap.
