DO NOT
install Style VS1 Dry Sprinklers into any threaded elbow, thread-by-thread
coupling, or fitting that interferes with thread penetration. The inlet of the Style VS1
Dry Sprinkler
SHALL NOT
bottom out in the fitting. Use a sample fitting to confirm
proper engagement.

To ensure unobstructed flow during operation, the Style VS1 Dry Sprinkler shall be
installed into a fitting that will prevent water and debris from accumulating at the
dry sprinkler’s inlet.

Verify that the exposed minimum barrel length in the heated space is measured
and maintained in accordance with the table below.
In a heated space, if a portion of the Style VS1 Dry Sprinkler extends
into an unheated space, it shall be installed with a continuous downward
slope along the entire length from the inside wall to the outlet end of the
dry sprinkler. No localized low points shall be present along the length of
the sprinkler in the unheated space. Refer to the drawing above.
