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.
•
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, there are two methods for ventilation,
including 'horizontal ventilation' and 'vertical ventilation'. Please use tool to
take out the cover before using and installing check valve on the hole.
•
The square air check valve for horizontal ventilation is not supplied.
