Choose a venting mode:
EXTRACTION-AIR MODE
NOTES:
•
Sufficient air is needed for proper combustion and exhaustion of gases
through the flue (chimney) of fuel burning equipment to prevent back
drafting. Ductless fans must always be vented to the outdoors.
•
When assessing the air pressure, the entire ventilation system in the house/apartment
must be taken into account, e.g. hob and/or gas cooker, this rule does not apply.
•
Government regulations must be observed for the conveyance of
exhaust air. If the extractor hood is used in circulating air mode with
activated carbon filter, there are no operating restrictions.
•
If you choose extraction-air mode,install check valve on the vent hole.
