Flexible Wall Subframe
When installing the fire dampers in the flexible walls it
is necessary to make a metal subframe onto which the
damper will be fixed with screws. Subframe should be
prepared according to the drawings below.
Support for Installation with Mortar
In fire damper installations with mortar, it may be
necessary to use wooden supports to prevent the casing
from deforming while mortar is setting.
Before filling the gap between wall and fire damper, close
the damper blade and install the wooden supports as
seen in the drawings below.
Place the wooden support as close as possible to the fire
damper blade!
Ensure that the damper is sufficiently supported!
