Refer to the section Construction supports characteristics for further
information.
Comply with the minimum distances indicated on section Minimum
distances .
Wall opening
A opening must be provided in the wall as indicated in the table and
in the drawing
Damper positioning
Connect fire damper to the galvanized steel duct as indicated in the
drawing.
Between fire damper and wall the maximum distance is 1000 mm.
The maximum length of the part of duct connected to the damper
is 2100 mm
The fire damper has to be fixed and suspended from the ceiling as
indicated in the drawing.
The hanging structure is composed by:
– 2 C-shaped steel profiles 10x41x41x41x10 mm
– 2 M10 threaded rods
– 4 M10 nuts
Position the threaded rods 135 mm from the connection between
fire damper and duct and at a distance of 50 mm from the side of
the damper.
Filling
Fill the space between the damper and the wall using Fire Batt
(Weichschott) sealing made from two rock wool panels with mini-
mum thickness of 50 mm and minimum density of 140 kg/m³.
Cover the duct over its entire length and fire damper with 2 rock
wool panels 50 mm thick and with a density of 140 kg/m³.
The panels must be covered externally with endothermic varnish
type PROSTOP E PASTE or HILTI CFS-CT (minimum thickness of 1 mm)
and with an internal perimeter sealant type PROMOSTOP E PASTE or
HILTI CFS-S ACR (minimum thickness of 1 mm).
Fix first layer of rock wool panel to the duct with screws Ø5 X 60 mm
and washers 40 X 40 mm, and the second one with screws Ø5 X 120
mm and washers 40 X 40 mm.
