The Central Model ELO LH Extra Large
Orifice Recessed Pendent and Pendent
Automatic Glass Bulb Sprinklers are
specifically designed for Extended
Coverage/Light Hazard as defined by
NFPA 13. They are Listed as Quick
Response, up to 20' x 20' (6.1 m x 6.1 m)
spacing. The ELO LH is Listed for
smooth flat horizontal ceilings as are all
Extended Coverage Light Hazard
Sprinklers.
The ELO LH provides the maximum in
design flexibility as it has a minimum
separation of only 11'-0" (3.3 m) and is
Listed for flows and pressures associated
with 16' x 16' (4.9 m x 4.9 m) , 18' x 18'
(5.5 m x 5.5 m) and 20' x 20' (6.1 m x 6.1
m) spacing.
They are intended for use with hydrauli-
cally designed systems using the flows
and pressures as shown in this literature.
For the purpose of determining the correct
flow and pressure to use in the hydraulic
calculations, all spacing is rounded up to
the next higher category. For
example,17'-6" x 15'-0" (5.2 m x 4.6 m)
spacing would be calculated at the Listed
18' x 18' (5.5 m x 5.5 m) flow and
pressure.
The advantage of the ELO LH is the
ability to cover large areas, up to 400
square feet (372 m
2
) , with pressures that
compare to 1⁄2" (15 mm) standard
sprinklers spaced at their maximum of
225 square feet (20.9 m
2
) . For example,
the ELO LH can cover 20' x 20' (6.1 m x
6.1 m) spacing or 400 square feet (372
m
2
) with less pressure than is required
with 1⁄2" (15 mm) sprinklers at 225 square
feet (20.9 m
2
) . (12.3 vs. 16.1 psi (0.8 vs.
1.1 bar) )
The Model ELO LH Sprinkler incorpo-
rates a specially designed deflector that
provides a much greater area of coverage
than standard commercial sprinklers. The
two (2) piece recessed escutcheon
assembly provides for 3⁄4" (19.1 mm) of
field adjustment.

Design Requirements — Light Hazard Extended Coverage Applications
Density .1 GPM/ft2- NFPA 13 All Editions
Design
Data
All Central Model ELO LH Re-
cessed Pendent and Pendent Auto-
matic Sprinklers must be installed
according to the current NFPA 13
Standard 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.
Wet pipe systems must be
protected from freezing.
Upon completion of the installation,
the system must be tested per
recognized standards.
The Model ELO LH incorporates the latest in heat-responsive glass bulb
technology. The operating mechanism consists of a 3 mm (76.2 mm)
liquid-filled frangible capsule that is only 20 mm in length.
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 the fire.
In the event of a thread leak,
remove the unit, apply new pipe joint
compound or tape, and reinstall.
Installation Sequence
Step 1. For Pendent and Recessed
Pendent sprinklers, the face of the
sprinkler fitting should be installed a
nominal 3⁄4" (±3⁄8") (20 mm (±9.5 mm))
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 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.
Installation
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 loca-
tion 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
operated. Replace any sprinkler
Caution: Minimum spacing between pendent and recessed
pendent sprinklers is 11'-0" (3.3 m).

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
