Preparation for Duct Connection
1. Remove the appropriate ducting knockout by inserting a screwdriver under one
end and prying it up. Then snip or break the attachment points.
2. Install the damper assembly to the range hood with the 4 screws supplied.
3. If discharge is vertical through a rectangular duct, remove the knockout in
section B only.
4. If the vertical discharge is through a 7" round duct, remove knockout sections
"A" and "B".
5. Mount the round collar over the opening on the hood by using 2 shorter
screws. Allow the bottom edge of the 7" duct to be inserted into the collar.
Installing Ductwork
Your new Haier range hood will operate at the highest efficiency if the number of
elbows and the length of the duct are kept to a minimum. Also, ensure the back
draft damper flap is attached to the damper frame assembly, which is supplied
with the hood, does not impede airflow significantly. This may be left in place
even if you install a wall or roof cap with another back draft damper.
