Safety clearances Ventilation line
• , WARNING
RISK OF FIRE
Grease deposits in the grease filter can catch fire.
The given safety clearance must be observed to
avoid heat buildup. Observe the specifications for
your cooking appliance, tf gas and electric cooktops
are used together, the largest given clearance
applies.
The appliance may only be installed directly next to
a cabinet or wall on one side. The wall or cabinet
clearance must be at least 2" (50 mm).
The clearance between the shelf on the cooktop and the
bottom of the extractor hood may not be less than 24"
(610 mm) in the case of electric cooktops and 30" (760
mm) in case of gas or combined ranges.
If the installation instructions for the gas cooking
appliance specify a larger distance, this must be taken
into account.

Note: The device manufacturer does not assume any
warranty for complaints attributable to the pipe section.
o The ventilation opening and the exhaust air ducts must
be made according to the local circumstances.
o The device achieves its optimum performance by
means of a short, straight exhaust air pipe and as
large a pipe diameter as possible.
o As a result of long rough exhaust air pipes, many pipe
bends or too-small diameters, the optimum extraction
performance is not achieved and fan noise is
increased.
The pipes or hoses for laying the exhaust air line must
consist of non-combustible material.
Smooth the connection area of the pipes before
installation.
o Seal the connection points of the pipes appropriately.
Round pipes
An inner diameter of O 8" (200 mm) is recommended.
Flat ducts
The inner cross-section must correspond to the diameter
of the round pipes.
O 8" (200 mm) approx. 50.3 inches 2 (324 cm 2)
o Flat ducts should have no sharp deflections.
o Use sealing strip for deviating pipe diameters.
Checking the wall
o The wall must be level, vertical and adequately load-
bearing.
o The depth of the bore holes must be the same length
as the screws. The wall plugs must have a secure grip.
o The enclosed screws and wall plugs are suitable for
solid brickwork. Suitable fasteners must be used for
other structures.
Fan operation
Note: Ventilation may not exit through an already
operational smoke or exhaust chimney, nor a duct used
for ventilating furnace installation areas.
o If the ventilation is intended to pass through a smoke
or exhaust that is not in operation, the responsible
area heating inspector must give approval.
o If the ventilation passes through an external wall, use a
telescope wall sleeve.
