Wall penetration for direct mounting
As the wall end cover fitting cannot be used for direct mounting in the cor-
ner of a room, the wall end cover described below can be created there
instead. The precondition for this is that the wall penetration is smaller
than the duct opening.
See Fig. 75:
Close off the wall penetration carrying the cables
insulation system, e.g. PYRO SIT
sistance class of the wall determines which insulation must be used.
Close off the butt of the fire protection duct on the wall with a calcium
silicate strip
remaining gap between the duct surface and the calcium silicate strip with
mineral wool and seal it with filler (min. thickness 2 mm).

Wall cover with calcium silicate strip
This procedure is also possible with dry/lightweight construction walls. In
this case, fasten the calcium silicate strip to the dual-planked dry con-
struction wall with quick construction bolts and also seal the residual gaps
with mineral wall and filler.
