■
For connection of following duct
■
Minimum and maximum distance between the wall and fire damper is unlimited
■
When installing the insulation, follow the ISOVER manufacturer's instructions
■
The damper and the duct must be suspended separately
■
The duct must be suspended on both sides of damper acc. to national rules
■
Duct between fire damper and fire separating construction must be suspended by using threaded rods and mounting profiles, or another
mounting system acc. to national standards
■
Load of the suspension system depends on weight of the fire damper and duct system
■
Max. distance between two suspension systems is 1500 mm
■
Duct at the point of penetration must be fixed to the fire separation structure
■
Following air-conditioning duct must be suspended or supported so that all load transfer from the following duct to the fire damper is absolutely
excluded. Adjacent duct must be suspended or supported, as required by the duct suppliers
■
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
