INSTALLATION TECHNOLOGY
Before installing the fire dampers, make sure that there are no damage, during transport or storage, that could block
the baffle.
Check that the baffle can be opened and closed (full opening and closing position). To open fire dampers WKP-O use
the actuator key.
The opening and closing must proceed smoothly (not stepwise).
Do not pull by baffle to open or close fire damper, it may cause permanent damage, not covered by the warranty.
Before installation verify dimensions of the gap between bottom blade and inside part of the housing under the blade,
and between top blade and inside part of housing above blade. The dimension of the gap cannot be lower than 4 mm.
Before installing, secure the fire damper, by dust and dirt, using a foil or other screening material. It can prevent
components of fire damper by damage.
Dampers to preserve of the declared resistance, insulation and smoke leakage EIS120, EIS90, should be installed on
wall, which was classified as EIS120, EIS90.
It is allowed to install WKP-O dampers in wall with other fire-resistance, should be remembered that fire-resistance in
this situation is resistance of lowest classified (in this regard) element in this system.
Ducts made of flammable and non-flammable materials can be connected to the damper. Ducts should be installed
that they cannot load the damper during fire. Ducts lengthening during fire can be compensated by support and knee.
ATTENTION: Distance between fire dampers or fire damper and construction elements must be compatible with
standard 1366-2:
a. Minimal 200 mm between fire damper, which are installed in different ventilating wires,
b. Minimal 75 mm between fire damper and construction element (wall/ceiling).

I. INSTALLATION TECHNOLOGY –RIGID WALL
a. 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, that is B+230 and H+100.
b. For the dampers which have height H=200 mm and H=300 mm installation opening should have height H+160
[mm] (acceptable 140÷180 [mm]).
c. Put the closed fire damper into the installation opening and support or suspend, in this way that the axis of the fire
damper baffle matches the axis of the wall, and ensure a concentricity of fire damper and installation opening. The
damper should be protected against possible undesirable stresses, which could lead to deflection of the housing,
e.g. by using assembly struts.
d. After setting the fire damper as described, fill the gap between the fire damper and the wall with cement, cement-
lime mortar or concrete.
e. After drying of the mortar (approx. 48 hours), remove used supports or suspensions, check the fire damper
correct operation and leave it in fully open position.
In order to avoid filling the holes above and below the actuator housing, the opening for the WKP damper can be made
as shown in the figure below.

II. INSTALLATION TECHNOLOGY - PROMADUCT CHANNEL
After setting the fire damper as described, and build it in wall, duct made of PROMATECT-L500 boards with 50 mm
thickness must be installed. The band around the duct must be made by PROMATECT-L500, with 50 mm thickness and
60 mm width. Connection of damper and the wall, and damper with the band must be made by K84 glue. The sides of
the duct and the band must be connected by using 4,2x90 –4,8x120 screws.

III. INSTALLATION TECHNOLOGY –STRUCTURES THICKER THAN 125 mm
In rigid walls, with thickness less than or equal to 125 mm, WKP-O fire dampers are installed in this way that an axis
of the fire baffle matches the axis of the wall, and ensure a concentricity of fire damper and installation opening.
In case when wall have more than 125 mm thickness: WKP-O fire dampers are installed in this way that the damper
border is flush with the wall surface (Fig. 6).

IV. INSTALLATION TECHNOLOGY –LIGHT WALL
a. Make an opening in the wall with the dimensions 230 [mm] (acceptable 210 ÷ 250 [mm]) greater than the
dimension B and 100 [mm] (acceptable 80 ÷ 120 [mm]) greater than the heigh H, That is B+230 i H+100.
b. For the dampers which have height H=200 mm and H=300 mm installation opening should have height H+160
[mm] (acceptable 140÷180 [mm]).
c. Make a frame of two layers of GKF boards 15 mm thick and the width relative to the width of opening, mounting
by screws remembering to carefully seal the contact edges with a mastic: Hilti Firestop Coating CP 673,
Promastop-Coating, Promaseal-Mastic or Soudal Firesilicone B1 FR.
d. Put the closed fire damper into the installation opening and support or suspend, in this way that an axis of the
fire baffle matches the axis of the wall, and ensure a concentricity of fire damper and installation opening.
e. After setting the fire damper as described, fill the gap between the fire damper and the wall with non-flammable
mineral wool of high density, 100 kg/m3 or more.
f. Seal the place of filling with mineral wool using the sealing compounds given in pts.2
g. Mount collar, both side of wall, made of GKF boards, 15 mm thick and 150 mm wide, using screws,
h. After mounting the collar, remove the supports or suspensions, check the fire damper correct operation and
leave it in open position.
