Installing Ductwork
Your new range hood will operate at the highest efficiency if the number of elbow
and the length of the duct are kept to a minimum. The back draft damper flap
attached to the damper frame assembly, which is supplied with the hood, does not
impede airflow significantly. You may leave this in place even if you install a wall
or roof cap with another back draft damper.
