: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. 
:Warning – 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.
Risk of electric shock! 
■ It must always be possible to disconnect 
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.
