information
Impor t ant saf et y informat i on
Read these instructions carefully. Only then
will you be able to operate your appliance
safely and correctly. Retain the instruction
manual and installation instructions for future
use or for subsequent owners.
Check the appliance for damage after
unpacking it. Do not connect the appliance if it
has been damaged in transport.
The appliance can only be used safely if it is
correctly installed according to the safety
instructions. The installer is responsible for
ensuring that the appliance works perfectly at
its installation location.
Only a licensed professional may connect
appliances without plugs. Damage caused by
incorrect connection is not covered under
warranty.
The surfaces of the appliance are easily
damaged. Avoid damaging them during
installation.
For the installation, observe the currently valid
building regulations and the regulations of the
local electricity and gas suppliers.
: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.
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.
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.
