Firestop Wrap Strip
Opening
1.Clean the plastic pipes or insulated pipe penetration.
Expansion of the intumescent material during a fire acts
to close the plastic pipe or pipe penetration. Very dirty
pipes with, for example, remains of mortar, may lead to
a delay in this closing action.Soiled plastic pipes or
insulated pipe penetrations should, therefore, be cleaned
in the area where the CP 648-E Firestop Wrap Strip is to
be installed.
Application of firestop system
2.Tightly wrap the required number of strips continuously
around the penetrant, and hold in place with tape.
3.Push the Hilti Wrap Strip into the opening until it is flush
with the substrate surface unless otherwise required by
the UL or cUL system. It may be required by the UL or
cUL system to clamp, wire or use a Hilti Retaining Collar
to secure the wrap strip in place for some applications.
4.If the UL or cUL system requires a cold smoke seal, then
apply the proper amount of Hilti FS-ONE sealant in the
opening over the wrap strip.
5.For maintenance reasons,a penetration seal can be
permanently marked with an identification plate and
fastened in a visible position next to the seal.
