1. DEVICE INSTALLATION INSTRUCTION
Before installing the fire damper check it for damage during transport or storage.
Check if the damper is able to open and close (full open and close position). In the case of
WKZ-O dampers open the damper with the actuator key. Full opening and closing shall be smooth (not
irregular). Do not pull the damper blade in order to open/close the damper. It may cause permanent
damage to the device, which is not covered by the warranty.
Before the installation verify the gap between the bottom blade and the inside part of the body
under the blade and also between upper blade and the inside part of the body above the blade. The
gap size can not be less than 4 mm.
Before the installation secure the damper with a foil or other material to protect it against dirt
and consequently damage to the elements of the damper.
To maintain EIS240 declared resistance, insulation and smoke leakage, the damper should be
mounted in walls, which were tested and rated as EI240.
It is acceptable to use WKZ-O dampers in walls with other fire resistance rating but in such a
case it should be kept in mind that EI fire resistance rating of the whole WKZ-O damper installation is
equal to the fire resistance rating of the lowest rated element of the system.
Ducts made of flammable or non-flammable materials can be connected to the fire damper. The
ducts must be installed in such a way that, in the event of fire, they do not transfer the load to the fire
damper. Duct lengthening in the event of fire can be compensated by supports and elbows.
NOTE: The distance between fire dampers and between fire dampers and structural members must be
provided in accordance with EN 1366-2 test standard:
a) min. 200 mm between the fire dampers installed in separate ventilation duct systems,
b) min. 75 mm between the fire damper and the structural element (wall/ceiling).

2. INSTALLATION TECHNOLOGY –RIGID WALL STRUCTURE
1. Make an opening in the wall - 230 [mm] (acceptable 210 ÷ 250 [mm]) greater than the dimension
B and 100 [mm] (acceptable 80 ÷ 120 [mm]) greater than the dimension H, i.e. B+230 i H+100.
2. Insert the closed damper into the assembly opening and support or suspend it so that the
actuator cover on the side of the thermal release is flush with the wall surface. The damper
should be protected against possible undesirable stresses, which could lead to deflection of the
body, e.g. by using assembly struts.
3. After setting the damper as described, fill the space above and below the actuator housing with
the native material of the wall, and then fill the gap between the damper and the wall with
cement mortar, cement-lime mortar or concrete.
4. After the mortar has dried (approx. 48 hours), remove the struts, supports or suspensions which
were used to install the damper. Check the correct operation of the damper, then leave the
damper in the open position.
5. Secure the fire passage with a GKF 15x150 [mm] board band on both sides of the building
partition, then cover the flanges with PROMASTOP-CC Liquid or PROMASTOP-E Coating.
