IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage a sprin-
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.
General
Description
The TYCO®Model CC2 Combusti-
ble Concealed Sprinklers are fast re-
sponse, upright, specific application
sprinklers designed to provide pro-
tection of specific light hazard com-
bustible, as well as non-combustible,
concealed spaces requiring sprinkler
protection. The CC2 Sprinklers com-
ply with the criterion for the protection
of combustible concealed spaces as
described in NFPA 13.
The Model CC2 Sprinklers are de-
signed for installation on BlazeMas-
ter®CPVC wet pipe systems and steel
wet pipe or dry pipe sprinkler systems
(refer to the respective Design Criteria
sections). They provide the following
features as compared to the 2.8K-fac-
tor Model CC1 Sprinklers described
on Technical Data Sheet TFP630:
• Can be used on steel dry pipe
sprinklersystems.
• Increasedspacingfrom10ft.(3,1

• Increasedcoverageareafrom100
ft2(9,3m2)to144ft2(13,4m2).
The effectiveness of the Model CC2
Sprinklers in combustible concealed
spaces was clearly evident during the
full scale fire testing for this product.
Concealed spaces between floors, as
well as low pitch attics (slope of 2:12
or less) are inherently shallow. Stan-
dard spray sprinklers, by design, have
an umbrella like spray pattern that
poses a difficult challenge when trying
to achieve effective coverage within a
shallow space. The Model CC2 Com-
bustible Concealed Space Sprinklers
have addressed the difficult “above
ceiling” fire challenge for both wet
pipe and dry pipe sprinkler systems.
NOTICE
The Model CC2 Combustible Con-
cealed Sprinklers described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the National Fire Protection Asso-
ciation, in addition to the standards of
any other authorities having jurisdic-
tion. Failure to do so may impair the
performance of these devices.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
Contact the installing contractor or
manufacturer with any questions.

The glass bulb contains a fluid that ex-
pands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter
the glass bulb allowing the sprinkler to
activate and flow water.

NOTE: In order to be considered
“non-combustible insulation-filled sol-
id wood or composite wood joist con-
struction,” the insulation (including in-
sulation provided with a combustible
vapor barrier), must completely fill the
pockets between the joists to the bot-
tom of the joists, and the insulation
must be secured in place with metal
wire netting. The metal wire netting is
intended to hold the insulation in place
should the insulation become wetted
by the operation of the CC2 Sprinklers
in the event of a fire.
Concealed Space Area (CPVC Pipe)
The area of the concealed space is
not limited; however, for both Fig. 2
and Fig. 3, where CPVC pipe is be-
ing utilized, draft-curtains or full height
walls must be provided at 1000 ft2(93
m2) areas. This draft curtain shall be
at least 1/3 the depth of the concealed
space or 8 inches (200 mm), whichev-
er is greater, and be constructed us-
ing a material that will not allow heat
to escape through or above the draft
curtain.
Concealed Space Size (CPVC Pipe)
The depth of the concealed space is
36 inches (915 mm) maximum to 12
inches (305 mm) minimum.
System Type (CPVC Pipe)
Light hazard, wet pipe system
Minimum Distance Between CC2
Sprinklers (CPVC Pipe)
The minimum distance between sprin-
klers is 7 Ft. (2,1 m).
NOTE: Minimum spacing does not
apply to any additional sprinklers
required for protection of Blaze-
Master CPVC that is offset over an
obstruction.

NOTE: The minimum resulting flow for
the 4.2K is 11.1 gpm, and the minimum
resulting flow for the 5.6K is 14.8 gpm.
Therefore, for coverage areas less
than the maximum permitted cover-
age area of 144 ft2, the 4.2K may pro-
vide a hydraulic advantage. The use of
the CC1 sprinkler having a K-factor of
2.8, minimum operating pressure of
10 psi, and resulting minimum flow of
9.5 gpm may provide a further hydrau-
lic advantage for yet smaller coverage
areas. The CC1 is described in Tech-
nical Data Sheet TFP630.
Obstructions (CPVC Pipe)

Use Of UL Listed BlazeMaster
CPVC Piping With Model CC2
Sprinklers
Only BlazeMaster CPVC product may
be used in concealed spaces requir-
ing automatic sprinklers, when used
in conjunction with Model CC2 Sprin-
klers. In order to use the BlazeMaster
CPVC product for wood truss or bar
joist construction, the horizontal run of
pipe must be a maximum of 6 Inches
(150 mm) above the ceiling or noncom-
bustible ceiling insulation, or 1/3 the
depth of concealed space (as mea-
sured from the top surface of the ceil-
ing to the bottom of the deck above),
whichever is smaller (Fig. 2). For insu-
lation filled solid wood or composite
wood joist construction, the horizon-
tal run of pipe must be a maximum
of 6 Inches (150 mm) above ceiling or
non-combustible ceiling insulation,
or 1/3 the depth of concealed space
(as measured from the top surface of
the ceiling to the bottom surface of
the joist insulation above), whichever
is smaller (Fig. 3). The CPVC piping
can then be used to supply the Model
CC2 Sprinklers, as well as the sprin-
klers below the ceiling. Unless modi-
fied by this Technical Data Sheet, all

1 inch (DN25) or larger pipe, a hanger
must be located at the truss nearest a
sprig for purposes of restraint. If using
3/4 inch (DN19) piping, all sprigs over
12 inches (305 mm) must be laterally
braced using methods described in
the NFPA standards.
Where the CPVC must be offset up
and over an obstruction and the pipe
exceeds the allowed horizontal posi-
tioning requirements specified above
as well as shown in Figure 2 and 3, ad-
ditional Model CC2 Sprinklers are to
be installed as shown in Figure 2 and

Concealed Space Size (Steel Pipe)
The minimum and maximum con-
cealed space depth is as follows:
For unobstructed wood truss con-
struction or concealed spaces of un-
obstructed bar joist construction (Fig.
4) the depth of the concealed space
is 36 inches (915 mm) maximum to 12
inches (305 mm) minimum.
For solid wood joist construction (Fig.
5), solid wood or composite wood joist
construction filled with non-combus-
tible insulation (Fig. 6), or obstruct-
ed wood truss construction (Fig. 7),
the maximum depth of the concealed
space is 54 inches from bottom of up-
per deck to top of ceiling, and the min-
imum depth is 6 inches from the bot-
tom of the upper deck joists to the top
of the ceiling joists.
System Type (Steel Pipe)
Light hazard, wet or dry pipe system
using steel pipe.
NOTES: Use of the 4.2K sprinklers in
dry pipe systems is permitted by section
8.3.4.3 of NFPA 13 (2007 edition) where
piping is corrosion resistant or internally
galvanized.

Installation
The Model CC2 Sprinklers must be
installed in accordance with this
section.
General instructions
The CC2 Sprinklers are to be installed
upright and with their frame arms in-line
with the pipe run (reference Figures 1 - 9,
as applicable).
Do not install any bulb type sprinkler if the
bulb is cracked or there is a loss of liquid
from the bulb. With the sprinkler held
horizontally, a small air bubble should be
present. The diameter of the air bubble is
approximately 1/16 inch (1,6 mm) for the
175° F (79° C) temperature rating.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 ft.-lbs. (9,5 to 19,0 Nm). Higher levels
of torque may distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler.
The Model CC2 Sprinklers must only
be installed in the upright position
with the deflector parallel to the up-
per deck. With pipe thread sealant ap-
plied to the pipe threads, use only the
W-Type 6 (End A) Sprinkler Wrench
(Fig. 9) for installation of the Mod-
el CC2 Sprinklers by applying the
wrench to the sprinkler wrench flats
only.
Care and
Maintenance
The Model CC2 Sprinklers must be
maintained and serviced in accor-
dance with this section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, permission to shut-
down the affected fire protection sys-
tems must be obtained from the prop-
er authorities and all personnel who
may be affected by this action must
be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb. (Ref. Installa-
tion Section).
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and devic-
es in compliance with this document,
as well as with the applicable stan-
dards of the National Fire Protection
Association (e.g., NFPA 25), in addition
to the standards of any other authori-
ties having jurisdiction. Contact the in-
stalling contractor or sprinkler manu-
facturer with any questions.
It is recommended that automatic
sprinkler systems be inspected , test-
ed, and maintained by a qualified In-
spection Service in accordance with
local requirements and/or national
codes.
