The duct must be suspended on both sides of damper after national rules.
■
Duct between fire damper and fire separating construction must be suspended by using threaded rods and mounting profiles, or another
anchoring system according national standards.
■
The dampers inspection holes are covered by insulation and therefore it's necessary to make an inspection hole on the connecting duct.
■
Load the suspension system depend on weight of the fire damper and duct system
■
Max. length between two suspension systems is 1500 mm.
■
Damper assembly procedures must be done so as all load transfer from the fire separating constructions to the damper body is absolutely excluded.
■
If the threaded rod is located inside the duct insulation, distance between threaded rod and duct is max 30 mm.
■
If the threaded rod is located outside the duct isolation, distance between threaded rod and isolation is max. 40 mm.
■
The insulation boards are fastened to the duct.
■
Reinforcing frame VRM2-B must be used for this kind of installation always. VRM2-B is not a part of the Fire damper and must be ordered
separately for each installation case!
