1.) All fire dampers has to be closed during installation process.
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).
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
to EN 1366-2 paragraph 13.5.
6.) Installation openings.

8. The fire damper can be integrated into a solid or gypsum wall construction or into solid ceiling
construction. Damper blade has to be inside of construction (labelled with BUILD IN EDGE on the
damper body).
7.) Placement of the openings in the wall.
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.
