SAFETY INSTRUCTIONS
Important notes about the extraction mode
WARNING
Risk of poisoning from exhaust gases sucked back. Never
operate the device in extraction mode simultaneously with
an open flue appliance when there is not adequate airflow
guaranteed.
Open flue combustion equipment (for example, gas, oil, wood or coal-fired
heaters, tankless water heaters, water heaters) pulls combustion air from the
room and runs it through an exhaust pipe or chimney to the outside. In the
extraction mode, indoor air is removed from the kitchen and the adjacent
rooms - without sufficient air intake this creates a vacuum. Toxic gases from the
chimney or extraction flue can thereby be sucked back into the living spaces.
• Always ensure that a sufficient supply of fresh air is guaranteed and that the
air can circulate.
• An air supply / extractor box alone does not ensure compliance with the
limit value.
Safe operation is only possible when the negative pressure in the room where
the appliance is located does not exceed 4 Pa (0.04 mbar). This can be achieved
when the air required for combustion can flow through openings that are not
closable, for example in doors, windows, in conjunction with an air supply/
extractor box or through other technical measures. In any case, consult a
qualified chimney sweep who can assess the entire ventilation of your house and
propose appropriate measures for adequate ventilation.
If the hood is used exclusively in the recirculation mode, unrestricted operation is
possible.
WARNING
Fire hazard from flying sparks. Only install equipment on a
fireplace for solid fuels (for example, wood or coal), if a closed,
non-removable cover is available.
