6.3 Vertical installation
Fire dampers can be suspended by using threaded rods and a mounting profiles. Load the
suspension system depend on weight of the fire damper.
Damper can be suspended from the ceiling construction or supported above the ceiling con-
struction.
Damper assembly procedures must be done so as all load transfer from the fire separating
constructions to the damper body is absolutely excluded. Back-to-back air-conditioning piping
must be hung or supported so as all load transfer from the back-to-back piping to the damper is
absolutely excluded.
Threaded rods longer than 1,5 m require fire-resistant insulation.
