Dimensions of installation opening
■
The fire damper can be integrated into a solid wall
construction made e.g. of normal concrete/masonry,
porous concrete with minimum thickness 100 mm or into
solid ceiling construction made e.g. of normal concrete
with minimum thickness 150 mm.
■
The fire damper can be integrated into a gypsum wall
construction with fire classification EI120 or EI 90.
■
The fire damper can also be integrated outside the wall
construction. Duct and the damper part between the wall
construction and the damper blade (labelled with BUILT
IN EDGE on the protective covering) must be protected
with fire-fighting insulation.

If damper is installed outside a construction it is necessary
to use reinforcing frame VRM2-B
