STEP 3 - INSTALL DUCTWORK
IMPORTANT:
•
An island range hood exhausts vertically up through the ceiling and out the roof.
•
Exhaust air must not be discharged into a ue that is used for exhausting fumes
from other appliances.
•
Exhaust air cannot be discharged into an attic space or a garage.
1. Plan where the ductwork will run between the range hood and the outside.

2. A short straight duct run will produce the most airow. Longer lengths and
elbow ducts will reduce the eciency of the blower.
3. Install a roof cap outside your home.
4. Connect a 6" metal duct to the cap and work backward toward the hood.
5. Ensure connections are completely sealed with duct tape.
STEP 4 - INSTALL CROSS BRACING
1. In the ceiling, install cross-braces between the ceiling joists.
NOTE: The bottom of the cross braces must be level to ensure that the island
hood hangs level.
