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:

using an approved
insulation system, e.g. PYRO SIT

NG or PYRO PLUG

Mini. The fire re-
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
1
(50 mm wide, 30 mm thick), e.g. OBO KSI. Plug the
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.
