Installation 1 - Wet
Using Plaster/Mortar/Concrete Filling
1. The supporting construction's opening must be prepared as depicted in the Opening and Wall Preparation section.
Opening surfaces must be even and cleaned off. The flexible wall opening must be reinforced as per the standards
for plasterboard walls.
2. The opening dimension D1 is driven by the nominal dimensions of the damper with added clearance.
3. Insert the closed damper into the middle of the opening so that the damper blade is in the wall. Use the bendable
hanger (2) to secure the damper against the wall using a suitable screw (F1).
4. Avoid any damage or bend to the damper housing from the weight of the filling.
5. Fill in the area between the wall and the damper with plaster, mortar or concrete filling (F2)
Note: Prevent the fouling of the damper’s functional parts, which could limit its correct functioning. The best way is to
cover the functional parts during installation. The seepage of the filling material can be prevented by using plaster
boards. However, these are not required for wet installation.
6. If necessary, uncover and clean the damper after installation.
7. Check the damper’s functionality
Installation Distances
According to the standard EN 1366-2, the minimum distance from the wall or ceiling to the damper body is 75 mm. For
multiple crossings through a fire resistant wall the minimum distance between two damper bodies is 200 mm. This
applies for distances between the damper and other nearby objects crossing the fire resistive wall.
