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.

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.
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.
Risk of injury!
Components inside the appliance may
■
have sharp edges. Wear protective gloves.
The appliance may fall down if it has not

Risk of electric shock!
Components inside the appliance may

■
the appliance from the power supply. The
appliance must only be connected to a
protective contact socket that has been
correctly installed. If the plug can no
longer be reached after installation, an
energy-isolating device in the phases must
be provided in the permanent electrical
installation in accordance with the
installation regulations. The permanent
electrical installation must only be wired
by a professional electrician. We
recommend installing a residual-current
circuit breaker (RCCB) in the appliance's
power supply circuit.
