Maximum distance of V-HIP sprinkler between other sprinklers along branchline:
6'-0" (1,83 m) - Center to center from V-BB, V-SD, and V-HIP Sprinklers.
10'-0" (3,05 m) - Center to center from Attic Upright Sprinklers.
Flow shaper position below peak, ridge, or deck:
For all roof pitches as per the listing from 4:12 – 12:12 the maximum flow shaper distance down is 22" (560 mm), and the minimum
flow shaper distance down is 16" (405 mm).
Minimum distance from truss:
6" (152 mm) from nearest edge of the truss.
Maximum distance from center line of the ridge:
6" (152 mm) on either side of the center line.
Draft curtains:
Where used to allow Attic Upright Sprinkler installation shall be constructed to contain heat, may be constructed of minimum ½"
(13 mm) plywood or equivalent.
Use of UL Listed CPVC BlazeMaster
Can be used to supply the sprinklers protecting the floor below the combustible concealed space when covered with 6" (152 mm) of
non-combustible insulation over the horizontal or vertical piping, and extending 12" (304 mm) on both sides of the center line of the
piping. If the piping is located in the joist, the width of the joist channel must be entirely covered to 6" (152 mm) above the top of the
piping. The area above the piping must be protected with the Model V-HIP's, V-BB's, V-SD's, or the Attic Upright Sprinklers.
Listed CPVC BlazeMaster
the following requirements, and in accordance with Figure 6:
Risers are vertical and protected by V-BB, V-SD, or V-HIP sprinklers located a maximum of 12" (304 mm) away from the riser centerline.
•
Model V-HIP, V-BB, or V-SD sprinklers are mounted directly to the branchline.
•
•
Model V-HIP, V-BB, or V-SD sprinklers are installed on arm-overs a maximum of 6" (152 mm) laterally from the center line of the branch line.
Model V-HIP, V-BB, or V-SD sprinklers are installed on vertical sprigs attached to the branchline.
•
•
Model V-HIP, V-BB, or V-SD sprinklers are installed on angled sprigs a maximum of 6" (152 mm) laterally from the centerline of the branchline.
Installed with a minimum lateral distance of 18" (456 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 needs to be verified for chemical compatibility with the CPVC piping at

Refer to Sections 8.8.5.2.1.3 and 8.8.5.2.1.7 of NFPA 13, 2016 for requirements if installed on greater than 2-1/2" (64 mm) diameter
piping.
Hydraulic requirements:
Viking V-HIP sprinklers must be calculated in accordance with the following figures and guidelines.
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 system's design.
The following figures cover hydraulic requirements for Viking V-HIP, V-BB, and V-SD sprinklers, when installed with Attic Upright (or
Standard Spray) Sprinklers.
Refer to figures-unless otherwise noted, all figures portray a 60' (18,3 m) roof span:
