2. The control mechanism has to be protected (covered) against damage and pollution during installation
process.
3. Min. gap for installation (installation opening) is 25 mm (circular dimension
Ø
D + 50 mm or square
dimension AxB + 100 mm).
4. Installation gap must be filled by approved material perfectly in all the installation space volume
(installation gap).
5.
The distance between the fire damper and the construction (wall, ceiling) must be minimum 75 mm
according to EN 1366-2. In case that two or more dampers are supposed to be installed in one fire
separating construction, the distance between the adjacent dampers must be at least 200 mm according
