Design Criteria,
CPVC Pipe
CC2 Temperature Rating
(CPVC Pipe)
175°F (79°C)
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 (Ref. Figure 2).
• Non-combustible, insulation-filled
solid wood or composite wood joist
construction (Ref. Figure 3).
NOTE: In order to be considered
“non-com bustible insulation-filled
solid wood or composite wood joist
construction,” the insulation (includ-
ing insulation pro vided with a combus-
tible vapor bar rier), must completely fill
the pockets between the joists to the
bottom of the joists, and the insulation
must be se cured 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 op eration 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 Figure 2 and
Figure 3, where CPVC pipe is being util-
ized, 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 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.
Concealed Space Size (CPVC Pipe)
The depth of the concealed space is
36 in. (915 mm) maximum to 12 in.
(305 mm) minimum.
System Type (CPVC Pipe)
Light hazard, wet pipe system
Minimum Distance Between Model
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
obstruc tion.
Maximum Distance Between Model
CC2 Sprinklers (CPVC Pipe)
12 ft (3,7 m)
Maximum Coverage Area (CPVC
Pipe)
144 ft² (13,4 m²)
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 (Ref.
Figure 2)
• 1-1/2 in. to 4 in. (40 to 100 mm) below
solid wood or composite wood joists
(Ref. 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 pro tection of BLAZE-
MASTER CPVC that is offset over an
obstruction.
Required Density (CPVC Pipe)
0.10 gpm/ft² (4,1 mm/min)
Minimum Operating Pressure
(CPVC Pipe)
7 psi (0,48 bar)
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 coverage
area of 144 ft², the 4.2K may provide
a hydraulic advantage. The use of the
CC1 sprinkler having a K- factor of 2.8,
minimum operating pres sure of 10 psi,
and resulting minimum flow of 9.5 gpm
may provide a further hydraulic advan-
tage for yet smaller coverage areas.
The CC1 is described in Technical Data
Sheet TFP630.
Obstructions (CPVC Pipe)
See Figure 8 in this data sheet for
obstructions rules.
Use of UL Listed BLAZEMASTER
CPVC Piping with Model CC2
Sprinklers
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 BLAZEMAS-
TER CPVC product for wood truss or
bar joist construction, the horizontal
run of pipe must be a maximum of 6 in.
(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 ceiling
to the bottom of the deck above),
whichever is smaller (Ref. Figure 2).
For insulation filled solid wood or com-
posite wood joist construction, the
horizontal run of pipe must be a maxi-
mum of 6 in. (150 mm) above ceil ing
or non-combustible ceiling insula tion,
or 1/3 the depth of concealed space
(as measured from the top sur face of
the ceiling to the bottom sur face of
the joist insulation above), whichever
is smaller (Ref. Figure 3). The CPVC
piping can then be used to sup ply the
Model CC2 Sprinklers, as well as the
sprinklers below the ceiling. Un less
modified by this Technical Data Sheet,
all other guidelines of the “BLAZEMAS-
TER — Installation Instruc tions & Tech-
nical Manual” must be met. When using
