Pre-Installation (continued)
6 . For ducted installations, adjust old duct work or install included
new duct work, as necessary, by following these guidelines:
-
Your venting system must vent to the outdoors either
horizontally through the back wall (4) or vertically through
the roof (5) .
-
A straight, short duct run will allow the hood to perform
most efficiently. Long duct runs, with elbows and
transitions will reduce the performance of the range hood .
Use as few of them as possible .
-
Use round metal duct work with a uniform diameter of
6 in . (152 mm) (included) . Larger ducting may be required
for best performance with longer duct runs .
-
Before making cuts, make sure there is proper clearance
within the ceiling or wall for the exhaust vent.
-
Fasten all connections between pieces of duct with sheet
metal screws and tape all joints with certified duct tape.
- Cap the exterior of the duct with a wall cap (6) or roof
cap (7) .
