Installation distances between BM-R90 fire protection
collars eg to external systems
The distance to external, tested systems (inspected and
approved) must be at least 50 mm between partitioned
sections.
If two Wavin BM-R90 feedthroughs are installed next to each
other, the distance between the pipes must be at least 100
mm in the case of special partitioned sections (sloping pipes,
partition via sleeve/socket or for ceiling installations). In the
case of straight pipes without sleeve/ socket in the partition
area, the collar casings can adjoin each other (distance 0 mm).
III. Wall installation
Minimum wall specifications: wall must be at least 100 mm
thick, made from concrete, aerated concrete, lime sandstone
or lightweight partition walls (two-layer panelling on both
sides with 12.5 mm plasterboard panels and mineral wool
infill). The pipe must be clamped on both sides at a distance
of ≤ 50 cm. For wall feedthroughs, a collar should always be
fitted on both sides of the wall.
Wrap insulating mat around the pipe. Open the collar and
position it around the pipe, whilst hooking in the push-in
fastening. Fill the remaining gap with cement or concrete (see
general recommendations (4)). Hold the collar firmly against
the ceiling and mark the positions of the mounting holes.
Rotate the collar and drill holes.
Insert plugs and fix the collar using screws and washers.
(Mounting the collar using the washers, plugs and screws
provided).
Repeat the steps described for the second collar required on
the opposite side.
