8.2 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
construction.
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.
