INSTALLATION DETAILS
Installation in solid walls
Installation of the ERK-MB-V in solid walls (shaft walls, shafts,
ducts and fire walls) made of, for example concrete, masonry ac-
cording to EN 1996 or DIN 1053; solid plaster board walls
according to EN 12859 or DIN 18163; apparent density ≥ 450
kg/m³ and wall thickness W ≥ 100 mm.
The distance to adjacent components (wall/solid ceiling) is at
least 75 mm.
The smoke extraction blade dampers can be installed next to each
other or about each other without clearance (max. 2 pieces) (see p.
9-11, additional mounting kit required).
Position of the blade damper axles: horizontal or vertical position
possible.
Wet installation
Circumferential gaps "s" must be completely filled with mortar
of category M10 according to EN 998-2 (previously: MG III ac-
cording to DIN 1053) or fire protection mortar of suitable
grades. The minimum gap size s
min
is ≥ 10 mm; maximum gap
size s
max
≤ 50 mm.
The mortar lining must be executed such that it is permanent
and, for example no mortar breaks occur. The information
given by the mortar manufacturer must be observed.
If the smoke extraction blade damper is installed during the
construction of the wall, the gaps "s" can be omitted.
The mortar bed depth must be executed in the minimum wall
thickness and may not be less than 100 mm. When performing
a mortar lining or direct installation, make sure that the hou-
sing is not pressed toward the inside (reinforcement). If
necessary, a statically active lintel must be provided.

Circumferential gap (at least 10 to ≤ 50 mm) with mortar of ca-
tegory M10 in accordance with EN 998-2 (previously: MG III
according to DIN 1053) or fire protection mortar of suitable gra-
des.
