S-BM2
Installation 1. WET - in the Wall
Using Plaster/Mortar/Concrete Filling
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 a thin layer)
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 gypsum plaster or mortar or concrete filling (F1) while paying
attention to prevent the fouling of the damper’s functional parts, which could limit its correct functionality. The best
way is to cover the functional parts during installation. To prevent seepage of the filling material, use of boards is
recommended. First, let the plaster or mortar or concrete filling harden and then perform the next steps.
4.After the filling hardens, remove the duct support from inside of the damper.
5.If needed, uncover and clean the damper after installation.
6.Damper connections to duct and connection with overlap boards must be filled with coating (F5)
7.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.
