Safe operation is possible only when the
partial vacuum in the place where the heat-
producing appliance is installed does not
exceed 4 Pa (0.04 mbar). This can be
achieved when the air needed for
combustion is able to enter through
openings that cannot be sealed, for
example in doors, windows, incoming/
exhaust air wall boxes or by other technical
means.
In any case, consult your responsible
Master Chimney Sweep. He is able to
assess the house's entire ventilation setup
and will suggest the suitable ventilation
measures to you.
Unrestricted operation is possible if the
vapour extractor hood is operated
exclusively in the circulating-air mode.
Danger of death!
Risk of poisoning from flue gases that are
drawn back in. If installing a ventilation
system in a room with a heat-producing
appliance connected to a chimney/flue, the
electricity supply to the hood must be
equipped with a suitable safety switch.
General information
Exhaust air mode
Note: The exhaust air must not be conveyed into a functioning
smoke or exhaust gas flue or into a shaft which is used to
ventilate installation rooms which contain heat-producing
appliances.
Before conveying the exhaust air into a non-functioning
■
smoke or exhaust gas flue, 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.
Exhaust duct
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.
Risk of fire!
Grease deposits in the grease filter may
catch fire. The specified safety distances
must be observed in order to prevent an
accumulation of heat. Observe the
specifications for your cooking appliance. If
gas and electric hobs are operated
together, the largest specified distance
applies.
Only one side of the appliance may be
installed directly next to a high-sided unit or
a wall. The distance between the appliance
and wall or high-sided unit must be at least
50 mm.
Risk of injury!
Components inside the appliance may
■
have sharp edges. Wear protective gloves.
The appliance may fall from the wall if it is
Risk of in jury!
■
not attached properly. All fastening
components must be fixed firmly and
securely in place.
Risk of in jury!
The appliance is heavy. To move the
■
appliance, 2 people are required. Use only
suitable tools and equipment.
Risk of electric shock!
Components inside the appliance may have
sharp edges. These may damage the
connecting cable. Do not kink or pinch the
connecting cable during installation.
Danger of suffocation!
Packaging material is dangerous to
children. Never allow children to play with
packaging material.
Because of long rough exhaust air pipes, many of which are
■
pipe bends or have diameters smaller than 150 mm, the
optimum extraction performance is not achieved and fan
noise is increased.
The pipes or hoses for laying the exhaust duct must consist
■
of non-combustible material.
Round pipes
An inner diameter of 150 mm, but at least 120 mm, is
recommended.
Flat ducts
The inner cross-section must correspond to the diameter of the
round pipes.
Ø 150 mm approx. 177 cm
Ø 120 mm approx. 113 cm
Flat ducts should have no sharp deflections.
■
Use sealing strip for deviating pipe diameters.
