• The installation must comply with the installation manual and the classification report.
• Axis orientation: see the declaration of performance.
• Avoid obstruction of adjoining ducts.
• Product installation: always with closed damper blade.
• Verify if the blade can move freely.
• Please observe safety distances with respect to other construction elements. The operating mechanism must also remain accessible: allow for a clearance of 200 mm around the housing.
• The air tightness class will be maintained if the damper is installed according to the installation manual.
• Rf-t fire dampers are always tested in standardised constructions according to EN 1366-2. The achieved results are valid for similar supporting constructions with a fire resistance, thickness and density equal or superior to the supporting construction used during the test.
• If the wall thickness exceeds the minimum thickness specified in our installation instructions, the following conditions apply to the sealing depth: - For flexible walls and sandwich panel system walls, the seal must always be applied over the full depth of the wall. - With rigid walls, rigid floors and plaster block walls, the minimum sealing depth as indicated in our installation instructions (often equal to the minimum wall thickness) is sufficient. Apply the seal at the height of the damper blade (from the wall limit indication).
• When installing a fire damper in a flexible metal stud wall, some installation methods do not require reinforcing profiles around the wall opening from a fire protection point of view (see below). Always follow the general instructions of the manufacturer of these wall systems when building this type of wall.
• The damper must remain accessible for inspection and maintenance.
• Schedule at least 2 visual checks each year.
