INSTALLATIONS
The FDC25 / FDC40 fire damper is always tested in standardized support frames (both
in a rigid wall and in a flexible wall) in accordance with EN 1366-2: 2015 table 3/4/5. The
results obtained are valid for all similar support frames which have a thickness and / or
density and / or fire resistance similar or greater than the one on the test.
The duct connected to the fire damper must be supported or hung in such a way that
the damper does not carry its weight. The damper must not support any part of the
surrounding construction or wall which could cause damage and consequent damper
failure. It is recommended to connect the damper to a flexible connection on either end
of the damper.
The damper driving mechanism can be placed on either side of the wall, however it
needs to be placed so that it ensures an easy access during inspection.
• Mounting is possible with the blade axis in horizontal or in vertical position.
• The installation must comply with the tests that were performed during certification.
• Avoid any obstruction of the moving blade by the connected ducts.
• The class of air-tightness is maintained in case the installation of the damper is made
in accordance with the technical manual.
• Operating temperature: 50 °C max.
• For indoor use only.
The gap in the installation opening between the fire damper and the wall/ceiling can be
increased by up to 50 % of the gap area, or decreased to the smallest dimension that is
shown in the table:
Installation in both, vertical and horizontal axis of rotation of the dampers blade is
acceptable (with the axis angle 0 - 360°).
The fire damper must be installed into a fire partition structure in such a way that the
damper blade in its closed position is located inside this structure (except for installation
with MF1 installation frame).
To help you find the suspension plane, a bendable hinge is provided on the damper body
and the red tape is placed on the casing to mark the location of the wall limit. This does
not apply for Applique/ MF1/ MF2 kit installations.
Check the operation of the fire damper before commencing the installation!
