NOTE: Distances over 24” are at the installer and user discretion.
1 ] Determine whether hood will discharge vertically (3¼” x 10”, 3¼” x 14” or 7” round),
or horizontally (3¼” x 10” or 3¼” x 14” only).
2 ] Decide where the ductwork will run between the hood and the outdoors.
3 ] Choose a straight, short duct run to allow the hood to perform most efficiently. Long duct
runs, elbows and transitions will reduce the performance of the hood. Use as few of them as
possible. When possible, use at least 2 foot straight runs before any turns. Larger ductwork
may be required for best performance with longer duct runs.
4 ] Install wall cap or roof cap (sold separately); ensure there is no leak in house insulation.
Connect metal ductwork to cap and work back towards the hood location. Use 2” metal foil
duct tape to seal the joints between ductwork sections.
