INSTALLATION IN LIGHTWEIGHT PARTITION
WALLS WITH METAL POSTS
LIGHTWEIGHT PARTITION WALLS WITH
PANELLING ON BOTH SIDES AND WALL
THICKNESS W ≥ 100 MM
Installation in lightweight partition walls with metal posts
and panelling on both sides (gypsum-bonded wall boards;
wall thickness ≥ 100 mm) according to classification to EN
13501-2 or comparable national standards.
Installation and mounting aids on site must be removed.
Wet installation of a fire damper, complete mor-
tar lining
The minimum distance of BKA-Ü from one another must be
at least 200 mm.
The minimum distance to adjacent components must be
(due to the design) at least 90 mm from the wall and at least
80 mm from the ceiling. The actual minimum distance may
slightly differ from the distances mentioned therein and
must be executed and adapted as a function of the wall con-
nection type.
Further information to be considered: see page 7 Minimum
distances or projecting ends.
Figure 14: Metal posts with required exchange parts for
wet installation (dimensions without reveal)
*When using a reveal (pos. 20; circumferential 12.5 mm), the
opening dimensions (see Figure 14) must increased by 25 mm.
Mounting information:
In the overlap area of the exchangeable profiles, they must be
riveted, crimped or screwed once on both sides. These con-
nections are only for fastening the individual metal profiles
during mounting.
