5.14 Fixing the fire damper
5.14.1 General
For installation with fire batt, the fire dampers must be
suspended with steel threaded rods (M10 – M12).
The rods have to be fixed to the ceiling slab; the
required fire resistance must not be compromised. 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.

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).
