CPVC piping may also be used exposed to provide wet system, vertical or angled, sprigs to Attic Upright
Sprinklers where:
The exposed portion of an angled sprig is a maximum length of 3'-0" (0,9 m), with the sprig being supported adjacent to the Attic
•
Upright Sprinkler, and vertical restraint is provided on the horizontal pipe runs with CPVC hangers.
Maximum exposed length on a sprig of 10'-0" (3,1 m), with a maximum lateral distance for the Attic Upright Sprinkler of 12" (305
•
mm) off of the centerline of the sprig. Sprig must also be supported at the swing joint to the Attic Upright Sprinkler.
Minimum 6" (153 mm) deep of non-combustible insulation extending 12" (305 mm) on each side of the pipe centerline for the
•
CPVC branchline feeding the Attic Upright Sprinklers.
If the CPVC branchline is installed inside the ceiling joist, the joist channel must be covered or filled with a minimum of 6" (153
•
mm) deep non-combustible insulation on top of the branchline feeding the Attic Upright Sprinkler sprigs.
Additional non-combustible insulation can be added to reduce the exposed length of the sprigs being used with the Attic Upright
•
Sprinklers.
Installed with a minimum lateral distance of 18" (458 mm) from any device that produces and releases heat, i.e attic furnace,
•
kitchen or bathroom exhaust fan, flue vents, heat lamps, and other such devices.
Insulation requirements are provided solely for fire protection purposes and not for freeze protection.
Non-combustible insulation being used needs to be verified for chemical compatibility with the BlazeMaster
piping at www.lubrizol.com
Obstruction criteria:
Refer to Figures 8 and 9.
Refer to Section 10.2.7.2.1.3 of NFPA 13, 2019 for requirements if installed on greater than 2-1/2" diameter piping.
Hydraulic Requirements:
Minimum design pressure:
7 psi
Minimum design density:
0.10 gpm/sq. ft.
For individual areas requiring more than four Attic Upright Sprinklers, the maximum area of the attic protected by Attic Upright Sprinklers
is 3,000 ft (279 m
) in any single area. In order to be considered a single area, the areas protected by the Attic Upright Sprinklers
2
must be separated by a minimum of 15'-0" (4,6 m), having that separation being protected by V-BB, V-SD, V-EP, or V-HIP sprinklers.
The design area shall include the most hydraulically demanding sprinklers, and in certain cases may require more than one set of
calculations to verify the systems design.
Refer to the Technical Data Sheets for the Model V-BB (Form No. F_042915), V-SD (Form No. F_043015), V-EP (Form F_011719),
and V-HIP (Form No. F_092116) Specific Application Attic Sprinklers for more information regarding hydraulic requirements
of Attic Upright Sprinklers.
