The Central Model ELO-16 GB FR Extra
Large Orifice Upright, Pendent and Recessed
Pendent Glass Bulb Automatic Sprinklers are
designed for Extended Coverage spacing in
Ordinary Hazard occupancies per NFPA 13
with very low pressure required.
The ELO-16 GB FR (upright and pendent)
is the first extended coverage ordinary hazard
sprinkler ever Approved by Factory Mutual.
As with any project that requires Factory
Mutual Approval, always consult the F.M.
Guidelines for their specific requirements.
The Model ELO-16 GB FR incorporate a
specially designed deflector that provides a
much greater area of coverage than most
commercial sprinklers. The extra large orifice
allows this greater area of coverage, while
requiring much lower pressure.
The ELO-16 GB FR are intended for use,
as all extended coverage sprinklers are, with
hydraulically designed systems and using the
flows and pressures as shown in this bro-
chure. All spacing is rounded up to the next
higher category. For example, 17'-6" x 15'-0"
(4.4m x 3.8m) spacing would be calculated at
the Listed 18' x 18' (5.5m x 5.5m) flow and
pressure.
Operation: The glass bulb capsule
operating mechanism contains a heat-
sensitive liquid that expands upon application
of heat. At the rated temperature, the
frangible capsule ruptures, thereby releasing
the orifice seal. The sprinkler then discharges
water in a pre-designed spray pattern to
control or extinguish the fire.
Installation Limitations:
• Unobstructed or non-combustible
obstructed construction*
• Minimum hydraulic design area of 5
heads or 1500 sq. ft., whichever is
greater.
• Minimum spacing between sprinklers is
12' (3.7m) for upright and 12'-6" (3.81m)
for pendent.
* WEB members of open WEB trusses must not exceed
1" (25 mm) diameter. Maximum ceiling slope of 2"
per foot (158 mm/m) .

Extended Coverage Ordinary Hazard Recessed Pendent Installation
All Central Model ELO-16 GB FR
Automatic Glass Bulb Sprinklers must
be installed according to current NFPA
13 Standards and these installation
instructions. 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.
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.
Note: Central's Model 65 or 401 escutcheon may be used. When using
Central's Model 65 escutcheon, the face of R.C. is to protrude 1/8"
±1/16" (3.2mm ±1.6mm) beyond the finished ceiling line.

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 should 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
System” , 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 reassembly or
otherwise reuse a sprinkler that has
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, additional
sprinklers should be installed to
maintain the protection level.
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 the 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 the model, style,
orifice, and temperature rating.
A fire protection system that has
been shut off after an activation
should be returned to service immedi-
Installation Sequence
Step 1. For Recessed Pendent
Sprinklers, the face of the sprinkler
fitting should be installed a nominal 3⁄4"
(±3⁄8")/ 19.1mm (±9.5mm) behind the
ceiling line. Adjustments are made via
the push-on escutcheon.
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
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 upright sprinklers shall be
oriented so the frame arms are parallel
with the branch line pipe per NFPA.
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.
