about
the
extractio
n 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 run 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.
