Options 1 and 2
1. Create a hole, corresponding to the damper’s nominal
dime 50 mm, in the building element.
If installing in plasterboard, a steel reinforcement frame
of 45x45 must be used.
2. The damper is secured flat and tight using fire-retardant
sealant between the damper and wall/joist structure
with all fastening lugs, which are opened out.
Screw Ø 5 mm with a minimum length of 45 mm to be
used when mounting in drywall. The screw is pulled
through the reinforcement stud.
3. Check that the gap between the damper and the wall
is 25 mm all the way round. Sealing is carried out by
caulking with mineral wool, min 40 kg/m
3
.
4. Fit the cover frame against the substrate with suitable
fixings. Now fasten the frame on the damper with steel
blind rivets Ø 5 mm through the pre-punched holes in
the mounting frame. Fit with blind rivets from inside out.
Ensure that the damper blade runs freely.
Building element (wall or joist structure) in fire resistance class EI90.
Damper’s fire resistance class: EI90 (ve ho i <–> o) S.

Option 1 Option 2
5. When using a Fire damper as a transfer-air or end
device, a non-combustible louvre intended for the
damper must be mounted on the non-connected sides
of the damper.
The minimum distance between the damper blade in
the open position and the louvre is 50 mm.
6. Connect the actuator device to the control unit and
carry out a function check.
7. Install the duct system according to applicable require-
ments. Ensure that connecting ducts systems do not
affect dampers during fire loading.
• The shortest distance between dampers must be
200 mm.
• The shortest distance to wall/floor must be 75 mm.
• The damper shaft must be mounted horizontally.
