Installation of Square fire dampers PK-I-S-EI90S and
120S into the wall
To seal between the wall and the fire damper Rockwool
with a min. density of 80-100 kg/m
3
can be used. Once
the fire damper is properly secured into the wall, cover
plates made of calcium-silicate can be used to close or
finish the wall openings (fig. 12).
Cover plates are not a part of fire damper and are
delivered as damper accessories, which must be
indicated and specified at the order.
Cover plates are fire resistant mastic Intumex MA.
From one side of the wall cover plates are mounted
together with the damper to the wall opening.
The entire opening between the fire damper and the
wall in the full depth of the wall around the fire damper
must be filled perfectly with Rockwool of Density 80-
100 kg/m
3
.
Once the above two procedures are fulfilled, then after
the opening from the other side of the wall can be
closed with cover plates to secure and finish the
installation.
A minimum opening diameter of Ød + 60 mm is
required for each size of fire damper for it to be
properly imbedded into wall cross section. Outer
diameter of cover plates for closure are normally Ød +
X as standard (see fig. 12a).
Metal anchors are used to fasten the cover plates to
the wall or ceiling made of concrete, bricks or building
blocks. All anchors should have a minimum length of
70 mm and to accommodate a screw diameter no less
than 5 mm.
After the installation is completed, the damper’s
operation must be tested (see operating manual).
X= 200 mm for dimensions PK-I-R/ Ø100 to Ø 560 mm
X= 300 mm for dimensions PK-I-R/ Ø630 to Ø 1000
mm
Outer diameter of scabs is stated by the ratio Ød + X (see fig.
12a).
For suspending the scabs to the wall or ceiling are used
metal anchors for given building construction (concrete,
bricks, porous concrete, etc.) with the depth of screw in min.
70 mm and with screw diameter for min. 5 mm.
