Installation 3. SOFT - in the Ceiling
Using Mineral Wool filing
1.The supporting construction opening must be prepared as shown on picture. Opening surfaces must be even and
cleaned off. The opening dimensions are driven by the nominal dimensions of the damper with added clearance. The
opening will be with the dimensions of W1 and H1.
2.Mount the hanger plates (A2) on the damper body only on the side which will be flush with the upper ceiling surface.
3.Insert the damper into the middle of the opening so that the damper blade is in the ceiling. On the previously
mounted hanger plates and if there on the prepared connecting duct.
4.Place the hanger plates (A2) flush with the damper body and the supporting construction from below.
5.From both sides of the supporting construction, fix the hanger plates the supporting construction and to the damper
with at least 6 screws per each hanger.
6.Fill in the area between the ceiling and the damper with mineral wool (F2) with a density of at least 100 kg/m3
thoroughly but in such a way that will not deform the body of the damper.
7.All the gaps around the filling and ceiling surface area at least 100 mm from the damper body must be covered by
fire resistive coating (F10).
8.Damper connections to duct and connection with overlap boards must be filled with coating (F5).
9.Check the functionality of the damper.
Installation Distances
According to the EN 1366-2 standard, the minimum distance from the wall or ceiling to the damper body is 75 mm.
For multiple crossings through a fire resistive wall, the minimum distance between two damper bodies is 200 mm.
This applies for distances between the damper body and a nearby foreign object crossing the fire resistive wall.
