3.7 Mounting the damper
The Kalfire W is delivered as standard without a damper. A damper
can be used to influence the degree of draught (suction) in the
flue. With the Kalfire W an external damper can be added. If there
is too much suction in the flue, we advise you to use a damper.
The amount of draught can be tested when you ignite the fire to
test the operation of the appliance. Pay extra attention to this
aspect, if the flue is longer than 7 metres. Normally the Kalfire W
can be controlled well using the air regulation (see section 5.3).
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 way the damper
functions.
