The opening in the wall around the duct in which the fire damper cartridge is mounted, is sealed with 2 layers of 50 mm-thick stone wool panels with fire resistant coating on one side (type PROMASTOP-CB 50 / PROMASTOP-CB/CC 50 / HILTI CFS-CT B).
3
The joints on these 2 layers must be installed staggered and covered all around the edge with coating (type PROMASTOP-CC / HILTI CFS-S-ACR).

5
The duct is coated with a layer (>1,5 mm) of endothermic coating (type PROMASTOP-CC / HILTI CFS-CT) on a width of 100 mm at the side the open damper blade exceeds.
6
The duct in which the damper is inserted doesn't need be centered in the opening (with max dimensions duct + 600 mm). The maximal distance between the damper and the edge of the opening is 400 mm.

General remarks

  • Verify if the blade can move freely.
  • The fire damper cartridge must remain accessible for inspection and maintenance.
  • Please observe safety distances with respect to other construction elements.

Product-specific remarks

  • The installation must comply with the installation manual and the classification report.
  • The results obtained in standardised supporting structures according to EN 1366-2 also apply to similar supporting structures with a fire resistance, thickness and density equal to or greater than the supporting structure of the test.
