Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb allowing the sprinkler to acti-
vate and flow water.
Design
Criteria
Design criteria is provided as follows:
• 200°F (93°C), Model CC3 Combusti-
ble Concealed Sprinklers with CPVC
pipe and horizontal slope above
sprinklers not exceeding 2:12. See
Page 2.
• 200°F (93°C), Model CC3 Combus-
tible Concealed Sprinklers with steel
pipe and horizontal slope above
sprinklers not exceeding 2:12 See
Page 4.
• For the installation of Model CC3
Combustible Concealed Sprinklers
installed with baffles at 2000 ft²
(186 m²), the design of the system
should be 6 sprinklers or 1000 sq. ft.,
whichever is greater.
Design Criteria,
CPVC Pipe
Area of Use (CPVC Pipe)
Horizontal (slope not exceeding 2:12)
combustible concealed spaces of:
• Unobstructed wood truss construc-
tion or unobstructed bar joist con-
struction. See Figure 2.
• Non-combustible, insulation-filled
solid wood or composite wood joist
construction. See Figure 3.
NOTE: In order to be considered
“non-combustible insulation-filled
solid wood or composite wood joist
construction,” the insulation (includ-
ing insulation provided with a combus-
tible vapor barrier), must completely fill
the pockets between the joists to the
bottom 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 Model CC3
Sprinklers in the event of a fire.
Concealed Space Area (CPVC Pipe)
The area of the concealed space is not
limited; however, for both Figure 2 and
Figure 3, where CPVC pipe is being uti-
lized, draft curtains or full height walls
must be provided at 1000 ft² (93 m²)
areas. In addition, the 5.6K sprinkler is
UL Listed for a 2000 ft² (186 m²) draft
curtain area for solid wood open truss
construction on edge or on face.
This draft curtain shall be at least 1/3
the depth of the concealed space or 8
in. (200 mm), whichever is greater, and
be constructed using a material that
will not allow heat to escape through
or above the draft curtain.
For information about antifreeze com-
patibility and approved configurations,
see the Technical Data section.
Concealed Space Size (CPVC Pipe)
The depth of the concealed space is
60 in. (1524 mm) maximum to 6 in. (152
mm) minimum.
System Type (CPVC Pipe)
Light hazard, wet pipe system

Minimum Distance Between Model
CC3 Sprinklers (CPVC Pipe)
Minimum sprinkler spacing is 7 ft
(2,1 m)
NOTE: Minimum spacing does not
apply to any additional sprinklers
required for protection of CPVC pipe
that is offset over an obstruction.
Deflector Position (CPVC Pipe)
• 1-1/2 in. to 4 in. (40 to 100 mm) below
upper deck for wood truss construc-
tion or bar joist construction. See
Figure 2.
• 1-1/2 in. to 4 in. (40 to 100 mm) below
solid wood or composite wood joists.
See Figure 3.
Minimum Distance Away From
Trusses (CPVC Pipe)
4-1/2 in. (114 mm)
Remote Area (CPVC Pipe)
The remote area is 1000 ft² (93 m²)
NOTE: The remote area does not
include any additional sprinklers
required for protection of CPVC pipe
that is offset over an obstruction.
Required Minimum Density
(CPVC Pipe)
0.10 gpm/ft² (4,1 mm/min)
Minimum Operating Pressure
(CPVC Pipe)
7 psi (0,48 bar)
Obstructions (CPVC Pipe)
See Figure 8 in this data sheet for
obstructions rules.
Use of UL Listed BLAZEMASTER
CPVC Pipe with Model CC3
Sprinklers
BLAZEMASTER CPVC product may
be used in concealed spaces requir-
ing automatic sprinklers, when used
in conjunction with Model CC3 Sprin-
klers. In order to use the BLAZEMAS-
TER CPVC product for wood truss or
bar joist construction, the horizon-
tal run of pipe must be a maximum
of 6 in. (150 mm) above the ceiling or
noncombustible ceiling insulation,
or 1/3 the depth of concealed space
(as measured from the top surface of
the ceiling to the bottom of the deck
above), whichever is smaller, see Figure
2. For insulation-filled solid wood or
composite wood joist construction,
the horizontal run of pipe must be a
maximum of 6 in. (150 mm) above
ceiling or non-combustible ceiling
insulation, or 1/3 the depth of con-
cealed space (as measured from the
top surface of the ceiling to the bottom
surface of the joist insulation above),
whichever is smaller, see Figure 3. The
CPVC pipe can then be used to supply
the Model CC3 Sprinklers, as well as
the sprinklers below the ceiling. Unless
