Suspension for rigid ceiling installation
Suspension systems are required for the dry
mortarless installation of the fire damper with
mineral wool in 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.

similar rigid material. Not necessary if connecting
rods directly to damper.

supported steel C profiles by two self tapping
screws 4.8 x 16 (make sure that it doesn’t

M8 screw and nut. Position of selftapping
screws is trough the middle of damper casing.
