Installation with installation block / installation kit
For installation without mortar-mix, installation
blocks or installation kits can be used:
–
in walls and ceiling slabs: ER, TQ / TQ2
–
on walls: WA / WA2
–
remote from walls and ceiling slabs: WE / WE2
If required, the installation kits must be assembled
by others in accordance with the planned use.
The installation kits are fixed according to the instal-
lation details. In lightweight partition walls, the fixing
screws must always be screwed into the metal sup-
port structure / wood support structure. The dry wall
screws must be long enough so that the damper can
be firmly fastened.
Installation block ER, installation kit TQ / TQ2
–
The installation block and the installation kits are
always installed centred in the installation
opening.
–
Circular installation opening ER:
Æ
D1, see
–
Square installation opening TQ / TQ2:
DN + 110 mm
–
If specified in the installation details, the cover
plates of the installation kits TQ / TQ2 can be
proficiently shortened on one side for installation
near the ceiling and floor.
Installation kit WE / WE2
–
Installation is carried out on sheet steel ducts
without any openings, with fire-resistant clad-
ding.
–
If Promat building materials are used, the wall /
ceiling connections must be clad in accordance
with this manual and the supplementary installa-
tion manual WE / WE2. Fittings must be config-
ured according to Promat® specifications.
–
If building materials from Paroc are used, the
wall connections must be made according to this
manual. Fittings must be configured according
to Paroc specifications.
–
Enough clear space is required to attach the
installation kit to the fire damper.
–
Fire dampers remote from walls and ceiling
slabs must be suspended or fixed.
Suspension systems with L
≥
1.5 m require fire-
resistant insulation. This is done with panel
materials or mineral wool insulation according to
the respective manufacturer's specifications.
–
For more installation details and for components
to be provided by others, see the supplementary
installation manual WE / WE2.
Installation with fire batt
The distance from the operating side spigot to the
wall has to be 215 mm for installation into fire batt
systems.
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.
Depending on the selected installation situation and
fire resistance duration, the fire damper casings
must be partially coated, thickness
≥
2.5 mm. The
actuator and release unit must not be coated.
Permitted alternatives:
–
Mineral wool strips > 1000 °C,
> 80 kg/m³, thickness = 20 mm
–
Sleeves (can be ordered separately)
–
Elastomer foam strips (flame-resistant, non-drip-
ping)
The following applies in Germany: For notes on
the use of elastomeric foams, see
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.
