FIRE DAMPER - FD
Possible damper orientations
Suspension for
mortarless ceiling
installation
Suspension systems are required for the Fire
Batt/
Weichschott installation of the fire damper with
mineral wool in floor ceiling 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.
1. Suspension strut should be connected with drop
rods (8/10 mm) to the ceiling slab above. It is used to
support the damper and ease the installation.
2. Support steel C profiles by 90 mm high peace of
aerated concrete or similar rigid material.
3. Suspend the fire damper to the steel C profiles.
Close the space between casing and floor/ceiling with
Firestop board (Firebatt) 2x50 mm
(minimum density of 140 kg/m
3
) and
coat the casing.
Damper blade must be closed
during installation!
Test the operation of the damper blade!
