Installation with installation kit
For installation without a mortar-mix, the installation
kit TQ can be used (only FKR-EU in spigot construc-
tion).
The installation kit is assembled on the fire damper
at the factory. Fixing to the wall / ceiling slab is car-
ried out according to the respective installation
details.
The installation is carried out centred in the installa-
tion opening.
For installation near the floor or ceiling, professio-
nally shorten the cover plate of the installation kit on
one side.
Fixing to the wall / ceiling slab is carried out
according to the respective installation details.
Installation with fire batt
The distance from the operating side flange to the
wall or ceiling has to be 370 mm for the spigot con-
struction and
Flange construction 342 mm.
Fire batt systems consist of two layers of mineral
wool slabs, gross density
≥
140 kg/m³.
Apply fire-resistant sealant to the cut faces of the
mineral wool slabs and fit them tightly into the instal-
lation opening. Seal any gaps between the mineral
wool slabs and the installation opening, gaps
between the cut faces of cut-to-size pieces, and
gaps between slabs and the fire damper by applying
fire-resistant sealant or coating. Use only sealant or
coating that is suitable for the fire batt system.
Apply ablative coating to the mineral wool slabs,
joints, transitions and any imperfections on the
coated mineral wool slabs; coating thickness
≥
2.5 mm.
Fix fire dampers on both sides of the wall, see
.
If the wall/ceiling is fairly thick, you must use addi-
tional layers of mineral wool slabs on side A.
Fire batt systems are not suitable for use below flex-
ible ceiling joints.
