The Central Model ESLO-20 GB Very
Extra Large Orifice Upright Automatic Glass
Bulb Sprinkler is specifically designed for
Extended Coverage/Ordinary Hazard for all
Groups as defined by NFPA 13. The ESLO-
20 GB is acceptable for installations in
unobstructed and non-combustible
obstructed construction consisting of
solid steel or concrete beams*. The
ESLO-20 GB is Listed for an 18" (457.2 mm)
commodity clearance from the deflector, as
standard sprinklers are per NFPA 13.
They are intended for use, as all extended
coverage sprinklers are, with hydraulically
designed systems and using the flows and
pressures as shown in this brochure. All
spacing is rounded up to the next higher
category. For example. 17'-6" x 15'-0" (5.3 x
4.6 m) spacing would be calculated at the
Listed 18' x 18' (5.5 x 5.5 m) flow and
pressure.
The advantage of the ESLO-20 is its
ability to cover large areas, up to 400 square
feet (37.2 m
2
) , with pressures that compare
to 1⁄2" (15 mm) standard sprinklers spaced at
their maximum of 130 square feet (12.1 m
2
) .
For example, the ESLO-20 can cover 18' x
18' (5.5 x 5.5 m) spacing or 324 square
feet (30.1 m
2
) with less pressure than is
required with 1⁄2" (15 mm) sprinklers at 130
square feet (12.1 m
2
) . (20.0 vs. 21.3 (1.4 bar
vs. 1.5 bar
)
The Model ESLO-20 GB Sprinkler
incorporates a specially designed deflector
that provides a much greater area of
coverage than most commercial sprinklers.
The Model ESLO-20 GB incorporates the
latest in heat-responsive glass bulb technol-
ogy. The operating mechanism consists of a
3 mm liquid-filled frangible capsule that is
only 2.0 cm (20 mm) in length.
Operation: The glass bulb capsule
operating mechanism contains a heat-
sensitive liquid that expands upon applica-
tion of heat. At the rated temperature, the

Installation
All Central Model ESLO-20 GB
Upright Automatic Glass Bulb Sprin-
klers must be installed according to
current NFPA 13 Standards and
these installation instructions. Devia-
tions 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.
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 sprinkler must be
installed in the upright 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 a Central
Sprinkler Wrench, to tighten the unit
into the fitting. A leak-tight joint
requires only 7 to 14 ft.-lbs. (9.5 to 19.0
Nm) of torque; a tangential force of 14
to 28 lbs. (62.3 to 124.5 N) delivered
through a 6" (150 mm) handle will
deliver adequate torque. Torque
levels over 21 ft.-lbs. (28.6 Nm) may
distort the orifice seal, resulting in
leakage.
The sprinkler shall be oriented so
the frame arms are parallel with the
branch line pipe for upright sprinklers.

operated. Replace any sprinkler
exhibiting corrosion or damage;
always use new sprinklers of the
same type and temperature rating as
replacements.
Because the discharge pattern is
critical to protection of life and
property, nothing should be hung or
attached to the sprinkler unit that
would disrupt the pattern. Such
obstructions must be removed. In the
event that construction has altered
the original configuration, the system
must be investigated and the protec-
tion level maintained.
Do not attempt to replace sprinklers
without first removing the fire protec-
tion system from service. Be certain
to secure permission from all authori-
ties having jurisdiction, and notify all
personnel who may be affected
during system shutdown. A fire
watch during maintenance periods is
a wise precaution.
To remove the system from service
mode, first refer to the system
operating guide and valve instruction.
Drain water and relieve pressure in
the pipes. Remove the existing unit
and install the replacement, using
only the special sprinkler wrench. Be
certain to match model, style, orifice,
and temperature rating.
A fire protection system that has
been shut off after an activation
should be returned to service immedi-
ately. Inspect the entire system for
damage and replace or repair as
necessary. Sprinklers that did not
operate but were subjected to corro-
sive elements of combustion or
excessive temperatures should be
inspected, and replaced if need be.
The Authority Having Jurisdiction will
detail minimum replacement require-
ments and regulations.
Guarantee: Central Sprinkler Com-
pany will repair and/or replace any
products found to be defective in
material or workmanship within a
period of one year from the date of
shipment. Please refer to the current

Care &
Maintenance
Sprinklers must be handled care-
fully. They must not be transported
or stored where ambient temperature
may exceed 100°F/38°C. For best
results, store them in a dry, cool
location in the original shipping
package.
Do not install sprinklers that have
been dropped or visibly damaged.
Sprinklers must never be painted,
coated, plated, or altered in any other
way from manufactured condition or
they may not function properly. Any
sprinklers altered in such manner
must be replaced.
The owner is responsible for the
proper operating condition of all fire
protection devices and accessories.
The NFPA standard 25 entitled,
“Inspection, Testing and Maintenance
of Water-Based Fire Protection
Systems” , contains guidelines and
minimum maintenance requirements.
Furthermore, the local Authority
Having Jurisdiction may have addi-
tional regulations and requirements
for maintenance, testing, and inspec-
tion that must be obeyed.
It is advisable to have sprinkler
systems inspected regularly by a
qualified inspection service. Length of
time between such inspections can
vary due to accessibility, ambient
atmosphere, water supply, and site
activity.
Do not attempt to reassemble or
otherwise reuse a sprinkler that has
