Installations within vertical light wall (gypsum blocks wall)
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
In case of paired installation refer to the section Fire dampers pairing
for further information
Damper positioning
Position the damper in the opening so that the side of the closing
mechanism extends as indicated in the table and in the drawing.
Filling
It is not necessary to insert any material, but simply cover the gap
between the damper and the wall by applying on both faces of the
wall a layer of plasterboard, to a total minimum thickness of 12,5 mm
per side, to make a frame 100 mm wide.
