Suspension for rigid floor installation
Suspension systems are required for the dry mor-
tarless installation of the fire damper with mineral
wool in floor slabs. Fire dampers can be suspended
from solid ceiling slabs using adequately sized
threaded rods. Load the suspension system only
with the weight of the fire damper. Ducts must be
suspended separately.
Installations
INSTALLATION
Damper blade must be closed during installation!
1. Suspension strut should be connected with drop
rods (8/10 mm) to the floor slab above. It is used
to support the damper and ease the installation.
2. When using L profile fixation, support steel C
profile with 50 mm high peace of aerated
concrete or similar rigid material. Not necessary
if connecting rods directly to damper.
3. Damper casing is fixed to suspended and sup-
ported steel C profiles by two self tapping screws
4.8 x 16 (make sure that it doesn’t interfere with
damper blade) with L profile hanger (detail A)
fixed to steel C profiles by M8 screw and nut.
Position of selftapping screws is trough the
middle of damper casing.
4. To finish the installation please follow the steps
(2. - 4.) from page 29.
