1 in. (DN25) or larger pipe, a hanger 

must be located at the truss nearest a 

sprig for pur poses 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 Figures 2 and 3, 

additional Model CC2 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.

Design Criteria, 

Steel Pipe

CC2 Temperature Rating 

(Steel Pipe)

175°F (79°C)

Area of Use (Steel Pipe)

Horizontal (slope not exceeding 2:12) 

combusti ble concealed spaces of:
•  Unobstructed wood truss construc-

tion or unobstructed bar joist con-

struction (Ref. Figure 4)

•  Solid wood joist construction (Ref. 

Figure 5) where the upper deck and 

ceiling joists may have a maximum 

depth of 12 in. (300 mm) and typical 

on center joist spacing of minimum 

16 in. (400 mm)

•  Non-combustible insulation filled 

solid wood joist or wood composite 

joist construction (Ref. Figure 6)

•  Obstructed wood truss construction 

(Ref. Figure 7)

NOTE: In order to be considered “non-

combustible insulation filled solid wood 

joist or composite wood joist con-

struction”, the insulation (including 

insulation provided with a combusti-

ble 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 CC2 Sprinklers 

in the event of a fire.

Concealed Space Area (Steel Pipe)

The area of the concealed space is not 

limited; however,
•  for unobstructed wood truss con-

struction or con cealed spaces of 

non-combustible, unobstructed 

bar joist construction (Ref. Figure 

4) 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.

•  for solid wood joist construction (Ref. 

Figure 5) and obstructed wood truss 

construction (Ref. Figure 7), blocking 

must be provided in each upper deck 

and ceiling joist channel at a max-

imum 32 ft (9,75 m) intervals. This 

blocking shall be installed to the full 

depth of the joists and be installed 

so as to not allow heat to escape 

through or above the blocking. The 

blocking must be constructed using 

a non-combustible material or the 

joist construction material.
Draft curtains must protrude below 

the joist a minimum of 6 in. (150 

mm) or 1/3 the space, whichever is 

greatest, and run parallel with the 

joist spaced at 31 ft (9,4 m) width 

maximum to limit the area to a max-

imum of 1000 ft² (93 m²). The draft 

curtain may be constructed of 1/4 

in. (6,4 mm) plywood to prevent 

heat from escaping beyond the 

area.

•  for non-combustible, insulation-filled 

solid wood joist or composite wood 

joist construction (Ref. Figure 6), 

the requirement for draft curtains or 

blocking does not apply.

Concealed Space Size (Steel Pipe)

The minimum and maximum concealed 

space depth is as follows:
For unobstructed wood truss construc-

tion or concealed spaces of unob-

structed bar joist construction (Ref. 

Figure 4) the depth of the concealed 

space is 36 in. (915 mm) maximum to 

12 in. (305 mm) minimum.
For solid wood joist construction (Ref. 

Figure 5), solid wood or composite 

wood joist construction filled with non-

combustible insulation (Ref. Figure 6), 

or obstructed wood truss construction 

(Ref. Figure 7), the maximum depth of 

the concealed space is 54 inches from 

bottom of upper deck to top of ceiling, 

and the minimum depth is 6 inches 

from the bottom 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.

Minimum Distance Between Model 

CC2 Sprinklers (Steel Pipe)

7 ft (2,1 m)

Maximum Distance Between Model 

CC2 Sprinklers (Steel Pipe)

12 ft (3,7 m)

Maximum Coverage Area (Steel 

Pipe)

144 ft² (13,4 m²)

Deflector Position (Steel Pipe)

1-1/2 in. to 4 in. (40 to 100 mm) below 

upper deck for wood truss construction 

or concealed spaces of non-combusti-

ble bar joist construction (Ref. Figure 4)
1-1/2 in. to 2 in. (40-50 mm) below 

solid wood joist (Ref. Figure 5) or top 

chord of a wood truss that has a depth 

greater than 4 inches
1-1/2 in. to 4 in. (40 to 100 mm) below 

non-combustible insulation filled solid 

wood joists or composite wood joists 

(Ref. Figure 6)

Remote Area (Steel Pipe)

The remote area for wood truss con-

struction or bar joist construction (Ref. 

Figure 4) or solid wood joist construc-

tion (Ref. Figure 5) is 1000 ft² (93 m²) 

for wet or dry pipe systems.
The remote area for non-combusti-

ble insulation filled solid wood joist 

or wood composite joist construction 

(Ref. Figure 6) is to be calculated per 

the requirements of NFPA 13.

Required Density (Steel Pipe)

0.10 gpm/ft² (4,1 mm/min)

Minimum Operating Pressure (Steel 

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 cov erage 

area of 144 ft

²

, the 4.2K may provide 

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 hydraulic advan-

tage for yet smaller coverage areas 

when designing wet pipe systems. The 

CC1 is described in Technical Data 

Sheet TFP630.

Obstructions (Steel Pipe)

See Figure 8 in this data sheet for 

obstructions rules.
