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 KTS-O-S 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.
During KTS-O-S damper test, to opening use a key, mounted on housing.
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, EIS60, EIS30, should
be installed on wall, which was classified as EIS120, EIS90, EIS60, EIS30.
It is allowed to install KTS 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. min. 200 [mm] between fire damper, which are installed in different ventilating wires,
b. min. 75 [mm] between fire damper and construction element (wall/ceiling).

I. INSTALLATION TECHNOLOGY - CEILING
a. Make an opening in the ceiling with the 70 [mm] (acceptable 60 ÷ 100 [mm]) greater than the nominal
dimensions of the damper: DN+70.
b. Put the damper into the installation opening and support or suspend it in order to maintain the imposed
dimension of the building i.e. the damper embossing must be on boundary of the building, and installation
opening axis must coincide with fire damper axis.
c. After setting the fire damper as described, mounting the mounting brackets, fill the gap between the fire
damper and the ceiling with cement, cement-lime mortar or concrete.
d. After drying of the mortar (approx. 48 hours), remove used supports or suspension, check the fire damper
correct operation and leave it in fully open position.

II. INSTALLATION TECHNOLOGY –RIGID WALL
a. Make an opening in the wall with the 70 [mm] (acceptable 60 ÷ 100 [mm]) greater than the nominal
dimensions of the fire damper: DN+70.
b. Put the damper into the installation opening and support or suspend it in order to maintain the imposed
dimension of the building i.e. the damper embossing must be on boundary of the building, and installation
opening axis must coincide with fire damper axis.
c. After setting the fire damper as described, fill the gap between the fire damper and the wall with cement,
cement-lime mortar or concrete.
d. 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.

III. INSTALLATION TECHNOLOGY –FLEXIBLE WALL
a. Make an opening in the wall with the 70 [mm] (acceptable 60 ÷ 100 [mm]) greater than the nominal
dimensions of the fire damper: B=DN+70 and H=DN+70.
b. Put the damper into the installation opening and support or suspend it in order to maintain the imposed
dimension of the building i.e. the damper embossing must be on boundary of the building, and installation
opening axis must coincide with fire damper axis.
c. 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/m3or more.
d. Seal the place of filling with mineral wool using the sealing compounds: Hilti Firestop Coating CP 673,
Promastop-Coating, Promaseal-Mastic or Soudal Firesilicone B1 FR.
e. Mount collar, both side of wall, made of GKF boards, 12,5 [mm] thick and DN+ 350 [mm] wide, using screws
(with the hole for the damper cutted out). For easy assembly, the collar can be made of two parts.
f. After mounting the collar, remove the supports or suspensions, check the fire damper correct operation and
leave it in open position.

IV. INSTALLATION TECHNOLOGY –HIGH WALL THICKNESS CONSTRUCTION
Figure 11. Installation method of fire dampers KTS in high wall thickness constructions
In rigid and flexible wall construction and in ceiling with thickness less or equal to 150 [mm], KTS fire dampers are
mounted in such a way that the damper installation limit, i.e. 52 [mm], is maintained and the damper embossing must
be on boundary of the building.
Whereas in case of walls and ceilings with thickness higher than 150 [mm]: the KTS fire dampers are mounted in such
a way, that the damper installation limit i.e. 215 [mm], is maintained and the damper flange must be on boundary of
the building (as in figure 11).

V. INSTALLATION TECHNOLOGY –INSTALLATION AWAY FROM WALL
CONSTRUCTION (SILICATE BOARDS)
a. Make an opening in the wall with the dimensions 100 [mm] greater than the nominal dimensions of the fire
damper, i.e. DN+100.
b. Push the ventilation duct into the installation opening and support or suspend it so that the channel and opening
alignment are maintained.
c. Mount the damper to ventilation duct, additionally support or suspend it.
d. On the mineral wool coverage section, apply 1 [mm] PROMASTOP Coating (made by PROMAT) layer.
e. The PROMASTOP Coating layer has to be applied on fire barrier in the place where the wool was sealed on both
sides, with a size about DN + 300.
f. Wrap the ventilation duct and the damper at the appropriate length of mineral wool with high density at least
100 kg/m3.
g. When the mineral wool is mounted, check correct functionality of the damper, then leave it in the open position.
