B. Installation Instructions
Viking sprinklers are manufactured and tested to meet the rigid requirements of approving agencies. They are designed to be
installed in accordance with recognized installation standards NFPA 13, NFPA 13R, and NFPA 13D, and any associated TIAs.
Deviation from the standards or any alteration to the sprinklers or cover plate assemblies after they leave the factory including,
but not limited to: painting, plating, coating, or modification, may render the sprinklers inoperative and will automatically nullify the
approval and any guarantee made by Viking.
The use of residential sprinklers may be limited due to occupancy and hazard. Residential fire protection systems must be designed
and installed only by those who are completely familiar with the appropriate standards and codes, and thoroughly experienced in
fire protection design, hydraulic calculations, and sprinkler system installation.
Before installation, be sure to have the appropriate sprinkler model and style, with the correct K-Factor, temperature rating, and
response characteristics. Viking residential sprinklers must be installed after the piping is in place to prevent mechanical damage.
Keep sprinklers with protective caps or bulb shields contained within the caps or shields during installation and testing, and any time
the sprinkler is shipped or handled.
1a. For frame-style sprinklers, install escutcheon (if used), which is designed to thread onto the external threads of the sprinkler*.
*Refer to the appropriate sprinkler technical data page to determine approved escutcheons for use with specific sprinkler models.
1b. For flush and concealed style sprinklers: Cut the sprinkler nipple so that the ½" or 3/4" (15 mm or 20 mm) NPT** outlet of the
reducing coupling is at the desired location and centered in the opening** in the ceiling or wall.
**Size depends on the sprinkler model used. Refer to appropriate sprinkler data page.
