Data
The Model GB-LO 17/32 Horizontal Sidewall Sprinklers are U.L. Listed for Extended
Coverage applications in light hazard occupancies only.
The Central Model GB-LO 17/32
Horizontal Sidewall Sprinkler must be
installed according to current NFPA
13 Standards. Deviations from these
requirements and standards or any
alteration to the sprinkler itself will
void any warranty made by Central
Sprinkler Company. In addition,
installation must also meet local
government provisions, codes and
standards as applicable.
The system piping must be
properly sized to ensure the minimum
required flow rate at the sprinkler.
Check for the proper model, style,
orifice size and temperature rating
prior to installation. Install sprinklers
after the piping is in place to avoid
mechanical damage, replace any
damaged units. Wet pipe systems
must be protected from freezing; refer
to the Central Bulletins on the Model
H-1 Dry Horizontal Sidewall
Sprinklers for use in dry pipe sprinkler
installations.
Upon completion of the installation,
the system must be tested per
recognized standards.
In the event of a thread leak,
remove the unit, apply new pipe joint
compound or tape and reinstall.
Installation Sequence
Step 1. The unit must be installed in
the horizontal position.
Step 2. Use only a non-hardening
pipe joint compound or Teflon* tape.
Apply only to the male threads.
Step 3. Hand tighten the sprinkler
into the fitting. Use the appropriate
Central sprinkler wrench to tighten
the unit into the fitting. A leak-tight
joint requires only 7-14 ft-lbs.
