Design Criteria,
CPVC Pipe
Area of Use (CPVC Pipe)
Horizontal (slope not exceeding 2 in 12)
combustible concealed spaces of:
• Wood truss construction or bar joist
construction (Ref. Figure 2)
• Non-combustible insulation filled
solid wood or composite wood joist
construction (Ref. 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 CC1 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. 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 which 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
CC1 Sprinklers (CPVC Pipe)
6 ft (3,1 m). Minimum spacing does
not apply to any additional sprinklers
required for protection of BLAZE-
MASTER CPVC that is offset over an
obstruction.
Maximum Distance Between Model
CC1 Sprinklers (CPVC Pipe)
10 ft (3,1 m)
Maximum Coverage Area
(CPVC Pipe)
100 ft² (9,3 m²)
Deflector Position (CPVC Pipe)
1-1/2 in. to 4 in. (40 to 100 mm) below
upper deck for wood truss construction
or bar joist construction (Ref. Figure 2).
1-1/2 in. to 2 in, (40 to 50 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)
The remote area does not include any
additional sprinklers required for pro-
tection of BLAZEMASTER CPVC that
is offset over an obstruction.
Required Density (CPVC Pipe)
0.10 gpm/ft² (4,1 mm/min)
Minimum Operating Pressure
(CPVC Pipe)
10 psi (0,7 bar)
Obstructions (CPVC Pipe)
All obstruction criteria per NFPA for
standard spray sprinklers apply (Ref.
Figure 8), unless modified by this tech-
nical data sheet.
UL Listed Use of BLAZEMASTER
CPVC Piping with Model CC1
Sprinklers
BLAZEMASTER CPVC product may
be used in concealed spaces requir-
ing automatic sprinklers, when used in
conjunction with Model CC1 Sprinklers.
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 in. (150
mm) above the ceiling or non-combus-
tible 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 (Ref. 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-combusti-
ble 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 insula-
tion above), whichever is smaller (Ref.
Figure 3). The CPVC piping can then
be used to supply the Model CC1
Sprinklers, as well as the sprinklers
below the ceiling. Unless modified by
this Technical Data Sheet, all other
guidelines of the “BLAZEMASTER —
Installation Instructions & Technical
Manual” must be met. When using 1
in. (DN25) or larger pipe, a hanger must
be located at the truss nearest a sprig
for purposes of restraint. If using 3/4
in. (DN19) piping, all sprigs over 12
in. (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,
additional Model CC1 Sprinklers are to
be installed as shown in Figure 2 and
3 to protect the BLAZEMASTER CPVC
product.
A minimum lateral distance of 18 in.
(460 mm) must be maintained between
the CPVC pipe and heat pumps, fan
motors, and heat lamps.
