3.3 Ducting Connection
- Attach the damper to the exhaust outlet on the top or rear of the range hood.
- Connect the duct pipe to the range hood's exhaust outlet. Use the 6-inch adapter if your existing ductwork is 6 inches.
- Route the ducting to the exterior of the building, ensuring minimal bends for efficient airflow. Seal all duct connections with appropriate duct tape.
