Installation 3 - Soft
Installation in a Soft Crossing with Fire Resistive Coating
With this installation we recommend using a flexible connection (see accessory FCR) due to thermal expansion of
connected ducts during a fire. Install the compensator so that the flexible part has a minimum distance of 50 mm from
the edge of a damper‘s blade in open position.
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. Prepare mineral wool installation segments with the thickness of the opening height (F3).
4. Apply a suitable fire resistive coating (F4) onto the damper at the place of its future placement; assemble and glue
the filling of the future installation with the same fire resistive coating.
5. 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).
6. Avoid any damage or bend to the damper housing from the pressure of filling insertion.
7. Apply fire resistive coating (F6), at least 2 mm thick and 100 mm wide, onto the exposed filling and wall edges
evenly from both sides of the wall. Do not apply this layer in the place where the mechanism, inspection openings
or manufacturer's label are located.
8. If necessary, uncover and clean the damper after installation.
9. Check the damper’s functionality.
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 needs to be 200
mm. This applies for distances between the damper and other nearby objects crossing the fire-resistive wall.
