• Your venting system must vent to the outdoors either horizontally through the back
wall(13) or vertically through the roof(14).
(refer to Fig. 5/Fig. 6/Fig. 7).
• Use 6 in. round metal ductwork for this Range Hood.
• The total duct length should not be more than 35 ft. Calculate the total effective length
of the ductwork by using the table below. For each fitting use the table to see its straight
duct equivalent.
• Fasten all ductwork with sheet metal screws and tape all joints with certified duct tape.
• If you must turn the path of the ductwork using elbows, keep the number of elbows to a
minimum for best performance. Use no more than
three
90 degree elbows. Ensure that
there is a minimum of 25.6 in. of straight vent between each elbow. Use elbows as far
away from the range hoods exhaust opening as possible.
• Cap the exterior of the duct with a wall cap (15) or roof cap (16). Never use (4 in.)
laundry-type wall caps. Use caulking to seal exterior wall or roof opening around the cap.
• The venting system must have a damper. If the roof or wall cap has a damper, do not
use the damper supplied with the range hood.

If using recirculating mode, ignore this section.
For recirculating mode, air will vent out of the front vent
holes. (17 in Fig. 8)
