Install Ductwork (Ducted Installations Only)
NOTE: Distances over 30” 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 ] The ducting from this fan to the outside of the building has a strong effect on the air flow,
noise and energy use of the fan. Use the shortest, straightest duct routing possible for best
performance, and avoid installing the fan with smaller ducts than recommended. Insulation
around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing
ducts may not achieve their rated airflow. Refer to the table on next page to help you plan the
most efficient installation..
NOTE: To use 6” round ducting, install a 3¼” x 10” to 6” round transition (not included). The
performances may be affected.
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.
