Installation 3. SOFT - in the Wall
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 flexible wall opening must be reinforced as per the standards for plasterboard walls. 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.Insert the damper as per the “Manipulation of S-BM2” section into the middle of the opening so that the damper
blade is in the wall. For damper widths greater than 600 mm, it is recommended to use a duct support inside the
damper during installation to avoid any damage caused to the damper housing by the weight of the filling.
For battery assembly:
a .Add the first layer of filling at the bottom of the opening - can be very thin.
b. Place the damper(s) on top while fixing them to the sides with screws (F11).
c. Stack the individual dampers on top of each other with caulk (F5) between them and fix together with screws
(F12) and to the wall with screws (F11) as depicted in fixing layout.
3.Fill in the area between the wall 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 duct/damper.
4.All the gaps around the filling and ceiling surface area at least 40 mm from the damper body must be covered by fire
resistive coating (F10).
5.Damper connections to duct and connection with overlap boards must be filled with coating (F5).
6.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.
