duct of minimum 4.5 metres and maximum 6 metres long
Kalfire W90/47S
Connection to a Ø300 flue duct is only possible with a chimney
duct of a minimum 4.5 metres and a maximum 6 metres long.

5.5 Mounting the damper (optional)

The fireplace is standardly delivered without a damper. an
external damper can be used to influence the draught (suction)
in the flue. if there is too much suction in the flue, we advise you
to use a damper. You can test whether a damper is necessary
while checking the fireplace. pay extra attention to this aspect,
if the flue is longer than 7 metres. normally, the fireplace can be
controlled well using the secondary air regulation.

Points for attention:
•
Make sure that the position of the damper is visible for the
end user. for this purpose, most of the operating knobs
have a position indication (open = auf or +, Closed = Zu or -).
•
Check the functioning of the damper before completing the
installation of the fireplace.
•
Make sure that the end user is familiar with how the
damper functions.
