Installing the hood
IMPORTANT
We recommend that two people carry
out the installation. Pay attention to the
procedure described in the assembly
instructions.
Preparation
• The vent hood should be on site before final
framing and wall finishing. This will help to
accurately locate the duct work and electrical
service.
• Installation will be easier if the vent hood is
installed before the cooktop and countertop are
installed.

Ductwork and wiring locations:

• Determine the exact location of the vent hood.
• Plan the route for venting exhaust to the outdoors.
• Use the shortest and straightest duct route
possible.
For satisfactory performance duct run should
not exceed 100' equivalent length for any duct
configurations.
• Refer to "Ductwork installation guidelines" chart
to compute the maximum permissible length for
duct runs to the outdoors (fig.
Ducting installation guidelines
• For safety reasons, ducting should vent directly
outdoors (not into an attic, underneath the house,
into the garage or into any enclosed space).

Keep duct runs as short and straight as possible.
Duct fittings (elbows and transitions) reduce air
flow efficiency.
Back to back elbows and „S" turns give very
poor delivery and are not recommended. A short
straight length of duct at the inlet of the remote
blower gives the best delivery.
Transition to duct from the integral blower or
remote duct transition as close to the downdraft
as is possible.
• In order of preference, use
Use of flexible metal round duct: Limit use to short
lengths and do not crush when making corners.
• Install a wall cap with damper or roof cap at the
exterior opening. Order the wall or roof cap and
any transition needed in advance.
• Use 6" rounded metal duct (5" optional) only.
