Exhaust air mode
9 WARNING
Risk of death
Risk of poisoning from flue gases that are
drawn back in. The exhaust air must not be
conveyed into a functioning smoke or exhaust
gas flue or into a shaft that is used to ventilate
installation rooms that contain heating
appliances. If the exhaust air is to be conveyed
into a non-functioning smoke or exhaust gas
flue, you must obtain the consent of the
heating engineer responsible.
If the exhaust air is conveyed through the outer wall,
a telescopic wall box should be used.
Ventilation line
Note: The appliance manufacturer does not assume
any warranty for complaints attributable to the pipe
section.
▯ The appliance achieves its optimum
performance by means of a short, straight
exhaust air pipe and as large a pipe diameter as
possible.
▯ As a result of long rough exhaust air pipes, many
pipe bends or pipe diameters that are smaller
than 6” (150 mm), 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.
Round pipes
An inner diameter of 6” (150 mm), but at least 4 _”
(120 mm), is recommended.
Flat ducts
The inner cross-section must correspond to the
diameter of the round pipes.
dia. 6” (150 mm) approx. 27^ sq in (177 cm
2
)
dia. 4 _” (120 mm) approx. 26_ sq in (113 cm
2
)
▯ Flat ducts should have no sharp deflections.
▯ Use sealing strip for deviating pipe diameters.
Preparing the ceiling
▯ The ceiling must be flat, horizontal and
adequately load-bearing.
▯ The depth of the bore holes must be the same
length as the screws. The wall plugs must have a
secure grip.
▯ The enclosed screws and wall plugs are suitable
for solid brickwork. Suitable fasteners must be
used for other structures (e.g. plasterboard,
porous concrete, poroton bricks).
▯ The max. weight of the extractor hood is 50kg.
