exceeded, i.e. the rotation axis of the fire damper’s blades cannot be outside the wall (off the wall surface). In the
case of space dividing elements with a thickness comparable to that of a fire damper, it is recommended that the fire
damper be installed in such a manner that its axis divides the thickness of the space dividing element precisely in
half. The built-in fire damper has to be coaxially connected to a ventilation duct. When installing a fire damper, be
sure that you do not damage its body, and in particular do not subject it to any stress. A fire damper cannot function
as a “structural element” of a duct or ventilation system in which it has been installed. It is unacceptable to drill
through the fire damper’s housing, screw in bolts/screws and other elements that pierce through the housing towards
the interior of the fire damper. Having connected the fire damper to a ventilation duct, check again if it works correctly.
When installing the mcr WIP type fire dampers, ensure in particular that the thermal release (fusible component) is
not damaged. It should not be exposed to high temperature (fire, welders, soldering irons), which causes its actuation
(it is a component that has been designed to be used once only and will not be replaced under warranty). Similarly,
the intumescent seals installed in the housing of the fire damper should not be exposed to high temperature.
Expansion of the seals makes it impossible to close the fire damper. After the installation has been completed, clean
thoroughly the fire damper and ensure that no debris has been left inside, as it could affect its correct operation.
