Installation of fire damper into rigid
building elements (walls and
intermediate floors) with fire
classification EI 60 (Fig. 1 and Fig. 4)
1.
Installation opening in the rigid wall or intermediate floor
must comply with the dimensions given in the table below.
Installation of fire damper into flexible
building elements (gypsum board walls
or similar) with fire classification EI 60
(Fig. 2 and Fig. 3)
1. Installation opening in the flexible wall must comply with
the dimensions given in the table below.
2. The fire damper blade must be closed during installation.
NOTE! The blade supports may not be removed
before completed grouting.
3. Place the fire damper centrally in the opening. Fire
damper positioning:
a.
The fire damper must be placed so that the blade is cen-
trally inside the opening in the intermediate floor or wall.
b. The marking (1) on the actuator side shall align with
the building element surface.
c. The damper axle can be placed in any position (Ø100
- Ø400) or in horizontal position when mounted in the
wall (Ø500 - Ø1000).
4. Support the damper properly in the opening. Fasten the
damper with the angle brackets (2), 1-4 pcs depending
on damper size. Use Ø5mm screws suitable for rigid
construction to lock the position.
5. Completely fill the gap M between the damper and the
building element using incombustible, rock based, fine-
grained gypsum or concrete cast. Protect the damper
whilst infilling.
6. Remove the blade supports (4) when finished grouting
(Ø500 - Ø1000).
2. The fire damper blade must be closed during installa-
tion. NOTE! The blade supports may not be removed
before completed grouting.
3. Place the fire damper centrally in the opening. Fire
damper positioning:
a. The fire damper must be placed so that the blade is
centrally inside the opening in the wall.
b. The marking (1) on the actuator side shall align with
the building element surface.
c. The damper axle can be placed in any position (Ø100
- Ø400) or in horizontal position when mounted in the
wall (Ø500 - Ø1000).
4. Support the damper properly in the opening. Fasten the
damper with the angle brackets (2), 1-4 pcs depending
on damper size. Use Ø5mm screws or anchors suitable
for flexible construction to lock the position.
5. Completely fill the gap S between the fire damper and
the wall opening on both sides by using fire-resistant
mass, e.g. Silacoll 100. The depth of the filling must cov-
er the total thickness of the boards (Figure 3).
6. Remove the blade supports (4).
7. Check the functioning of the fire damper and proper move-
ment of the blade. Clean the damper, if necessary. Place
plastic covers on the openings and keep them covered, until
ducts are connected to the damper.
8. To reset the fuse mechanism: Turn the handle towards the
OPEN position until the mechanism clicks and the blade
locks into position.
9. Manual function testing of the motorized fire damper can be
performed with the tool delivered with the
actuator. When connected to a power supply, function testing
is done by using the switch of the thermal trip (3). NOTE! If
you open the damper blade manually with the tool, be sure
to release the damper back to the closed position before
switching on power.
10. Connect ducts to the damper according to the instructions
provided by the designer and the manufacturer. Access
panel should be placed next to the fire damper to enable
necessary cleaning and inspection. Suspend the ducts
according to instructions from the manufacturer and ensure
that the ductwork does not cause any load on the damper
installation.
11. If the fire damper is used as an air transfer or air terminal
device, it must be equipped with a protective grille. The dis-
tance between the grille and the damper blade in the open
position must be at least 30 mm. In case of large fire damp-
ers, an extension piece must be installed between the grille
and the damper blade. A circular duct of suitable length can
be used as an extension piece.
12. When dampers are to be mounted next to one another, the
distance between the dampers should be ≥200mm (Fig. 4).
