FLEXIBLE CONNECTING PIECE TYPE FS
Figure 14: Flexible connecting piece type FS
•
Flexible connecting piece consisting of profiled connection
flanges (galvanised sheet steel) with elastic intermediate
piece made of polyester fabric PVC-coated on both sides,
standard flammable according to EN 13501-1, with welded
lip seals (sealing degree C according to EN 13180 / EN
1507; temperature-resistant from -20° to 80°C). Flexible
part of the connecting piece (polyester fabric) must have a
length l
min
of 100 mm when mounted, this gives an instal-
lation dimension of approx. L=160 mm.
•
The required equipotential bonding must be carried out
on-site according to the VDE or local regulations. The fire
dampers must not be subject to mechanical stress under
any circumstances.
•
Flexible ventilation ducts made of steel or aluminium can
be used instead of the flexible connection pieces.
•
Flexible spigot must be installed in the scrapped state. This
may reduce the free cross section. An extension piece may
be necessary.
•
For H ≥ 400, observe table 2 page 4.
