KITCHEN VENTILATION
A normal cooker hood is installed over the kitchen stove. The hood should be used only
when cooking. It is still necessary to install an extract vent, connected into the general
ventilation system. The extract air volume should be 20 l/s. The cooker hood should not be
connected to the Fenix ventilation unit.
If needed the cooker hood can be connected to the Fenix ventilation unit exhaust air duct,
for instance in high-rise buildings where it is difficult to install a separate duct for the
cooker hood. Use of separate cooker hood or a combination of a cooker hood and an
extractor is recommended to ensure sufficient suction effect.
