Despite flexible connector installation, the fire damper
must be installed in the construction support so that its
weight does not affect damper’s installation position both
during normal operation and in case of fire.
It is recommended not to compress flexible connectors in
the installation phase.
Flexible connector must be at least 100mm long and in
order that possible duct thermal expansions are balanced.
Take care that the flexible connector does not interfere
with opening / closing movement of the blade.
Refer to the section Technical data p. 9 for blade expo-
sition values.
