Installation manual of KTS-O-(E)S type fire dampers in building barrier
Version: 3.1
INSTALLATION MANUAL OF KTM, KTS-O-(E)S TYPE FIRE DAMPERS
1. Prior to the installation, fire dampers should be checked whether there has been no
damage to the dampers during transportation or storage.
2. Check whether the damper blade could be opened and closed (fully open and closed
position). To open fire dampers KTS-O-E use the actuator key. The full opening and
closing must proceed smoothly (not stepwise).
The fire dampers, to maintain declared EIS120 fire resistance class, should be installed in
walls which are verified and classified as EI120.
It is allowed to use KTS fire dampers for different fire resistance class walls (EI30, EI60,
EI90), however it must be understood that the fire resistance class EI of the whole finished
installation is corresponding to the least classified element in the installation.
INSTALLATION TECHNOLOGY
a) Vertical barrier (wall) figure 1
Variant I (without using pos. 1 ÷ 5)
1. Make an opening in the wall with the minimal size DN+70 [mm]
2. Put the fire damper into the installation opening to the depth of flange. The fire
damper should be suspended or supported it in such way that axis of the fire damper
should coincide with the axis of the installation opening (coaxiality).
3. After setting the fire damper in accordance to the guidelines, fill the gap between
the fire damper and the wall with cement and lime mortar or concrete. In place of
cement and lime mortar and concrete, the fire protective mortar e.g. PROMASTOP
MG III made by PROMAT may be used.
4. After drying of the mortar, remove used supports and suspensions which were used
during installation of the fire damper.
Variant II – Recommended by SMAY company
1. Make an opening in the wall with the minimal size DN+70 [mm]
2. Install the mounting plate pos. 1 to the fire damper using M6 screws pos. 2,3,4.
3. Make holes for the rawlbolts pos. 5according to the drawing.
4. Put the fire damper into the installation opening to the depth of flange in the way
that axis of the fire damper should coincide with the axis of the installation opening
(coaxiality) and screw it by means of rawlbolts pos. 5.
5.
After setting the fire damper in accordance to the guidelines, fill the gap between
the fire damper and the wall with cement and lime mortar or concrete. In place of
cement and lime mortar and concrete, the fire protective mortar e.g. PROMASTOP
MG III made by Promat can be used.
