Important notes on exhaust air operation
WARNING
Danger of poisoning from recirculated exhaust gases! Do not operate
the appliance in extract air mode if it is operated together with a room
air-dependent fireplace and sufficient air circulation is not
guaranteed.
Room air-dependent fireplaces such as gas, oil, wood or coal heaters, boilers or
instantaneous water heaters draw the air from the room and lead it outdoors through
an exhaust pipe or chimney. In extract air mode, air is extracted from the kitchen and
neighbouring rooms. Without sufficient supply air, negative pressure is created. Toxic
gases from the chimney or exhaust pipe can be sucked back into the living rooms.
• Make sure that sufficient fresh air supply is guaranteed and that the air can
circulate.
• A supply air/exhaust air wall box is not sufficient to ensure compliance with the
limit value.
Safe operation is only possible if the negative pressure at the location of the fireplace
does not exceed 4 Pa (0.04 mbar). This can be achieved if the air required for
combustion can flow in through non-closable openings in doors and windows in
conjunction with a supply air / exhaust air wall box. In any case, have a master
chimney sweep advise you and assess the entire ventilation system of the house. If
necessary, they can tell you the necessary measure for ventilation.
If the cooker hood is used exclusively in recirculation mode, operation is possible
without restriction.
Important note on dismantling the unit
• Disassembly is the same as installation/assembly in reverse order.
• Have a second person help you during disassembly to avoid injury.
