product label for safe usage and health information.
•	Instructions below are general guidelines — always
refer to the applicable drawing in the UL Fire
Resistance Directory or Hilti Firestop Systems Guide
for complete installation information
Opening
1.	Clean the opening. Penetration and penetration
supporting structures must be installed in
compliance with local building and electrical
standards.
Application of Firestop Blocks
2a.If no penetrations are located, build up Firestop
Block CFS-BL, firmly seated, within opening.
2b.If penetrations are located, build up Firestop Block
CFS-BL, firmly seated, while cutting blocks with a
knife to suit the placed penetrations.
3.	Finish building up Firestop Blocks until entire
opening is filled.
4.	Completely fill cable spaces, gaps between blocks
and pipes, and joints with FS-ONE Firestop Sealant
(as required).
5.	For maintenance reasons, a penetration seal could
be permanently marked with an identification plate.
In such a case, mark the identification plate and
fasten it in a visible position next to the seal.
Re-installing cables or other penetrations
•	Remove or cut the block from the seal.
• 	Install the penetrant and re-lay the block in
compliance with the approval. Fill gaps and spaces
with FS-ONE Firestop Sealant (as required).
Single cables can be run through joints between
blocks or a hole can be drilled through a block using
a sharpened piece of metal pipe or tubing.
Not for use
•	In wet rooms, outdoors or exposed to the weather
or UV radiation (can be done only after applying an
additional silicone coating, i.e. CP 601S).
Storage
•	Store only in the original packaging in a location
protected from moisture and direct sunlight
