Suspension for
mortarless floor
installation
Damper blade must be closed during installation!
Suspension systems are required for the dry mortarless
installation of the fire damper with mineral wool in
floor slabs. Fire dampers can be suspended from solid
floor 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
(8/10mm) to the floor. It is used to support the damper
and ease the installation.
2. Support steel C profiles by 90 mm high piece of
aerated concrete or similar rigid material.
3. Suspend the fire damper to the steel C profiles.
Close the space between casing and floor with Firestop
board (Firebatt) 2x50mm (
≥
140 kg/m3) and coat the
damper casing.
Test the operation of the damper blade!
Ensure that the damper is sufficiently supported!
