How do I use the included installation hardware?
Viking provides a 3/4" pipe guide with each VK480 concealed pendent fire sprinkler. This guide helps installer keep the correct distance between the sprinkler and the face of a finished wall.
Simply slide the looped end over a vertical 3/4" CPVC pipe before connecting the sprinkler head (or any end fittings). Then, use the included screws to attach the guide to a stud (2-by-4), ensuring that the center of the fitting and the centerline of the sprinkler are no further than 6" apart. Then, finish the installation in accordance Viking's instructions, attaching the sprinkler and cover plate to the pipe with a threaded CPVC elbow.
