5.14 Fixing the fire damper
5.14.1
General
For installation remote from walls and ceilings and
installation with fire batt and fire protection block bull-
head, the fire dampers must be suspended with steel
threaded rods. The rods have to be fixed to the ceiling
slab; the required fire resistance must not be compro-
mised. Use only fire-rated steel anchors with suitability
certificate. Instead of anchors, you can use threaded
rods and secure them using nuts and washers. Secure
the threaded rods above the ceiling using steel nuts and
washers. Threaded rods up to 1.50 m long do not
require any insulation; longer rods do require insulation
(according to Promat® work sheet 478, for example).
Load the suspension system only with the weight of the
fire damper, ducting must be suspended separately.
For weights [kg] of FKRS-EU fire dampers see
.
In addition to the fixing systems described in this
manual, you may also use fixing systems that have
been approved by accredited testing institutes. This
applies in particular to the fire damper installation near a
wall or in a corner (when angle sections or mounting
plates are used).
