: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 which 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.
:Warning
Danger of death!
Risk of poisoning from flue gases that are
drawn back in.
Always ensure adequate fresh air in the room
if the appliance is being operated in exhaust
air mode at the same time as room air-
dependent heat-producing appliance is being
operated.
Room air-dependent heat-producing
appliances (e.g. gas, oil, wood or coal-
operated heaters, continuous flow heaters or
water heaters) obtain combustion air from the
room in which they are installed and discharge
the exhaust gases into the open air through an
exhaust gas system (e.g. a chimney).
In combination with an activated vapour
extractor hood, room air is extracted from the
kitchen and neighbouring rooms - a partial
vacuum is produced if not enough fresh air is
supplied. Toxic gases from the chimney or the
extraction shaft are sucked back into the living
space.
■ Adequate incoming air must therefore
always be ensured.
■ An incoming/exhaust air wall box alone will
not ensure compliance with the limit.
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.
:Warning
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.
:Warning
Risk of injury!
■ Components inside the appliance may have
sharp edges. Wear protective gloves.
Risk of injury!
■ The appliance may fall down if it has not
been properly fastened in place. All
fastening components must be fixed firmly
and securely.
Risk of injury!
■ The appliance is heavy. To move the
appliance, 2 people are required. Use only
suitable tools and equipment.
Risk of injury!
■ Changes to the electrical or mechanical
assembly are dangerous and may lead to
malfunctions. Do not make any changes to
the electrical or mechanical assembly.
