GB 8
The discharge opening may in no case be connected to a
duct that is also being used for other purposes.
Bear in mind any local regulations concerning the ventilation
of gas appliances.
We advise the use of as large a discharge duct as possible.
A duct with a smaller diameter will have a low extraction
capacity and produce higher noise levels.
Bends produce resistance. Make sure that the duct has a
smooth run and has as few bends as possible. Draw the
flexible pipe out as far as possible.
The discharge stump has a diameter of 125 mm. It is best if
the discharge pipe also has this diameter.
The extractor hood is fitted with a Volume control valve
(VCV). This must be configured according to the extraction
capacity of the central ventilation. This is done using plates.
Both plates are fitted as standard and the VCV is set to a
capacity of 120 m
3
per hour. Sliding down and removing one
plate provides a capacity of 150 m
plates provides an extraction capacity of 180 m
3
per hour. Removing both
3
per hour.
