INSTRUCTIONS FOR USE
Firestop Foam CFS-F FX is approved as a permanent firestop seal for indoor
applications. The foam can be used to form a firestop seal around cables,
cable trays, combustible / non-combustible pipes passing through medium-sized
openings in fire compartment walls and ceilings.
The approval must be observed. For industrial use only. The European
Technical Approval and the technical data sheet can be obtained via your
local Hilti contact. Store in unopened container in a dry place.
Read these instructions and safety precautions before using the product.
Expiry date: See date printed on the manifold (DD / MMM / YY).
Use of the foil pack after this date is not permissible!
Transport and storage: Store in a cool, dry, dark place at a temperature of
+5°C to +25°C / +41°F to +77°F.
Foil pack temperature: Must be between +10°C and +35°C / +50°F and +95°F
during application.
Base material temperature: Must be between 0°C and +40°C / 32°F and
+104°F during application.
Installation instructions: The operations to be carried out are illustrated in
pictograms 1 – 7 / 
3
Clean the opening to be sealed. The material around the opening must be dry,
in sound condition and free from dust or grease.

Check the foil pack holder for damage and ensure that it functions correctly. Slide
the foil pack into the holder. Caution: Never use damaged foil packs and / or
damaged or badly soiled foil pack holders.
Remove the cap. Screw the mixing nozzle all the way onto the foil pack and
tighten it securely. Check that the black mixing element is in place inside the
nozzle! Do not use damaged mixing nozzles. Do not, under any circumstances,
modify or tamper with the mixing nozzle. The foil pack should only be used
together with the mixing nozzle supplied. A new mixing nozzle must be used with
each new foil pack.
Insert the holder containing the foil pack into the dispenser: Press the
release button on the dispenser, pull the piston rod back as far as it will go and
then insert the holder containing the foil pack into the dispenser.
The foil pack opens automatically when dispensing begins. Never pierce a hole in
the foil pack! This will cause the system to malfunction.
Discard the unevenly mixed initial quantity: The foam dispensed by the first
stroke of the dispenser must be discarded, e.g. in the empty outer packaging
material.
INSTALLATION INSTRUCTIONS

After approx. 10 minutes (at 23°C) the foam becomes hard and it can then be cut.
Note
After hardening, any projecting foam can be trimmed off to the specified minimum
depth. Trimmed-off scraps of hardened foam can be placed in the next opening
and fresh foam applied around these.

Apply the firestop foam in the opening to be sealed. The mixed components
of the foam react and begin to expand approx. 30 seconds after application (at
23°C). Fill the opening completely with firestop foam, including gaps between
individual cables, etc.
Note
It is generally best to begin in the middle of the opening, building up the foam by
working from bottom to top. In openings with access from only one side, begin
at the rear and work toward the front. The foam will harden in the mixing nozzle
during pauses (i.e. >1 minute at 23°C; >20 seconds at 35°C). The mixing nozzle
must then be changed. Release the pressure from the piston rod before changing
the mixing nozzle. Use formwork made from an air-permeable material (e.g.
perforated cardboard) when filling openings in ceilings.
Recommendation: Residues in the foil pack should be completely dispensed. The
remaining firestop foam can then be used for the next opening.
The foam can be shaped or smoothed by hand (if necessary) after approx. 5
minutes (at 23°C). Wear protective gloves!
Subsequent installation of cables or pipes
Additional cables or pipes can be installed in the opening without difficulty. Do
not exceed the approved maximum number and size of cables or pipes.
1.  The cable or pipe may be pushed directly through the foam. Where necessary,
use a suitable tool (screwdriver or drill bit, etc.) to make a hole in the foam
before pushing the cable or pipe through. Do not damage existing cables.
2.  Seal any remaining gaps carefully with Firestop Foam CFS-F FX.
Additional instructions The firestop foam is not suitable for outdoor
applications. The firestop foam is sensitive to UV light and is not weather-
resistant. Do not allow the hardened foam to remain in contact with standing
water.

Figure 3
Aperture framing
Where the required seal thickness tA is higher than the wall or floor thickness tE, a
support frame (E
1) made from material of class A1 or A2 according to EN 13501-1
(e.g. gypsum board) shall be installed to support the Hilti Firestop Foam CFS-F FX
as illustrated in figure 1.
The frame may be installed inside the opening, its depth being minimum the
seal thickness t
A, in case of a penetration seal in a wall centred in relation to the
wall. Alternatively a frame made from gypsum board may be fixed to the wall or
floor around the opening (width w
A ≥ 50 mm for wall applications, wA ≥ 75 mm for
floor applications, total thickness wall plus frame ≥ seal thickness t
A). The frame
must be fixed by minimum 2 metal screws per side of the frame with a maximum
distance of 150 mm between the screws. In case of a penetration seal in a wall
the frame shall be installed on both sides so that the penetration seal is centred in
relation to the wall.
SEAL THICKNESS
For some floor applications a pipe sleeve (F) can be casted into concrete floor
made from PVC-pipes, diameter 75 mm – 110 mm, with 200 mm length mounted
flush to the bottom side of the floor as illustrated in figure 2.
Aperture framing: In case of a flexible wall with no insulation between the
panels, an insulation that does not fill the space between the linings completely,
an insulation of a density of less than 100 kg / m
3
or an insulation made from glass
wool, an aperture framing has to be installed. It has to be made from material
used to construct the wall, i.e. studs and boards with a minimum board thickness
of 12.5 mm, as illustrated in figure 3.

ADDITIONAL COMPONENTS FOR PIPE PENETRATIONS
In some cases of plastic pipes and metal pipes with combustible insulations
(reaction to fire class B to E according to EN 13501-1) a Hilti Firestop Bandage
CFS-B (see ETA-10 / 0212) is wrapped around the pipe.
The bandage is positioned with half of its width (62.5 mm) within the seal (central
marking line at the surface of the seal) and fixed with wire. For necessary number
of layers of the bandage see the relevant chapter (special care has to be taken
to use the correct position when the required Hilti Firestop Foam CFS-F FX seal
thickness is higher than the wall or floor thickness).
TYPE OF INSULATION FOR PIPES
The following types of foamed elastomeric insulation products may be used as
pipe insulation:
Manufacturer Product designation
Armacell International GmbH
Armaflex AF (CE marked according to EN 14304), Armaflex SH,
Armaflex Ultima, Armaflex HT
NMC Group Insul-Tube (nmc), Insul-Tube H-Plus (nmc)

L’Isolante K-Flex
L’Isolante K-Flex HT, L’Isolante K-Flex ECO, L’Isolante K-Flex ST,
L’Isolante K-Flex H, L’Isolante K-Flex ST Plus
Named material may be used in make of an insulation hose, bandage / wrap
or plates. If a protect insulation DP is used, it should be made from the same
elastomeric material as the thermal pipe insulation itself.

ADDITIONAL ATTRIBUTES
Hilti Firestop products are comprehensively tested and individually tailored to
the technical requirements of a building’s mechanical and electric installations.
In addition to their superior behaviour in passive fire protection, Hilti Firestop
products also meet the requirements in building technology that continue to gain
significance and also help the designer and installer in meeting these additional
requirements. The assessment of fitness for use has been made in accordance
with EOTA ETAG N
