Draft Curtains:
Where used to allow Attic Sprinkler installation shall be constructed to contain heat, may be constructed of ½” plywood.
Asymmetrical Slopes:
Refer to Figure 4.
Use of UL Listed CPVC Blazemaster Piping (Wet Systems Only):
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 Viking Model V-BB’s, V-SD’s, or the Attic Upright Sprinklers.
Listed CPVC Blazemaster piping may also be used exposed to feed wet systems using Viking V-SD sprinklers in accordance with the
following requirements, and in accordance with Figure 5:
•
Risers are vertical and protected by V-SD or V-BB sprinklers located a maximum of 12” away from the riser centerline.
•
Model V-SD or V-BB sprinklers are mounted directly to the branchline.
•
Model V-SD or V-BB sprinklers are installed on arm-overs a maximum of 6” (152 mm) laterally from the center line of the branch line.
•
Model V-SD or V-BB sprinklers are installed on Vertical Sprigs attached to the branchline.
•
Model V-SD or V-BB 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” (457 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 CPVC piping at

Obstruction Criteria:
Refer to Figures 6—12
Refer to Sections 8.8.5.2.1.3 and 8.8.5.2.1.7 of NFPA 13, 2013 for requirements if installed on greater than 2-1/2” diameter piping.
Hydraulic Requirements:
Viking V-SD 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 systems design.
The following figures cover Hydraulic Requirements for Viking V-SD Sprinklers only, and when installed with Standard Spray Sprinklers.
For areas using Viking V-BB Sprinklers and/or Viking Attic Upright Sprinklers refer to the applicable data sheets.
