Wet installation (mortar lining)
If the fire damper is installed by means of mortar lining, it
must be completely filled with mortar of class M 10 to M
15 according to EN 998-2 or fire protection mortar of
corresponding grades or with concrete or plaster mortar
suitable for the wall or ceiling type.
If the fire damper is installed during the assembly of
the
wall/ceiling, the annular gap dimensions can be
smaller than specified.
The mortar bed depth must not be less than 130 mm.
The mortar lining must be executed such that it is perma-
nent. The information given by the mortar manufacturer
must be observed.
INSTALLATION IN SOLID WALLS
Installation in solid walls (shaft walls, shafts, ducts and fire
walls) made of, for example, concrete; masonry according
to EN 1996 or DIN 1053; solid plaster wall boards according
to EN 12859; apparent density ≥ 450 kg/m³ and wall thick-
ness W ≥ 100 mm.
Installation positions
for large wall thicknesses
*) The mortar bed depth is always at least 130 mm.

The minimum distance of fire dampers from one another
must be at least 200 mm.
The minimum distance from adjacent components
(wall/solid ceiling) is at least 75 mm.
