The dampers are installed into square or rectangular (KP series) and round (PL series) air ducts of ventilation systems, and the
apertures of ventilation shafts, division walls and fire partitions.
The installation of the dampers into ventilation systems must be carried out in consideration of the air flow direction.
While installing electrically actuated dampers provide for sufficient space for the actuator inspection.
When preparing the fire-safety dampers for installation the damper casing must be fitted with wooden spreader bars to prevent
deformation, torsional twisting or geometry perturbation of the casing which may result in flap jamming and, eventually, loss of the
damper functionality.
Following the damper installation into the shaft, wall or ceiling filler structure section and upon complete curing (immobilization) of the
mortar make sure to remove the wooden spreader bars. The damper must open and close freely without excessive friction.
To install the dampers into the apertures of wall or ceiling slabs fill up the gaps between the damper casing and the aperture. The gaps
are filled with fire-resistant mortar.
The damper design enables its attachment to air ducts and other ventilation system components by means of flanges as well as its
installation into filler structures. Under any installation scenario the mating structure fire-resistance level must be upgraded by using extra
fire insulation to at least match that of the filler structure of the respective fire-safety zone.
KP DAMPER INSTALLATION
The dampers can be installed in any position into vertical and horizontal channels of fire-protection structures. The damper installation
openings must be made in such a way so as to prevent the transfer of loads caused by the fire-protection structures to the damper casing.
The adjoining air duct must be suspended in such a way so as to prevent the transfer of air duct load to the damper flange. There must
be at least 350 mm of unrestricted clearance for accessing the control elements. Make sure to arrange an inspection hole. While carrying
out the installation mind size K. When two or more dampers are installed into the same fire-protection separation structure the distance
between the two adjacent dampers must be at least 200 mm.
The damper must be installed in such a way that the damper flap lies in the fire-protection divider structure plane while closed. If
such installation is not possible, the damper casing part between the fire-protection separation structure and the damper flap must be
insulated with a suitable material pursuant to the applicable standards.
The damper control mechanism must be protected against damage and contamination. Avoid damper casing deformation during the
embedding. After the installation the flap must not catch against the damper casing while opening or closing.
Fire-safety dampers can be integrated into a tight wall structure – e.g. made of conventional concrete work of minimum width
W = 100 mm or into a plasterboard wall of the necessary fire resistance class or into a tight ceiling structure – e.g. made of conventional
concrete of minimum width W = 150 mm.
The recommended values for construction openings are given below.
