The Recessed, Flush, and Extended
Escutcheons for the ELO-16 GB Dry
Pendent Sprinklers are separable two-
piece designs which allow installation of
the sprinklers and pressure testing of
the fire protection system prior to
installation of a suspended ceiling. They
also permit removal of suspended
ceiling panels without having to first
shut down the fire protection system
and remove the sprinklers.
Operation: When the ELO-16 GB Dry
Pendent Sprinkler is in service, water is
prevented from entering the assembly
by the Plunger Assembly, a Plug & O-
ring in the Inlet (Spool) of the Sprinkler.
The glass Bulb contains a fluid which
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass Bulb, and the Bulb Seat is
released. The GuideTube drops,
allowing the Plug & O-ring to withdraw
from the Inlet, which then allows the
sprinkler to activate and flow water.
WARNING
The ELO-16 GB Dry Pendent Sprinklers
described herein must be installed and
maintained in compliance with this
document, as well as with the applicable
standards of the National Fire Protec-
tion Association, in addition to the
standards of any other authorities
having jurisdiction. Failure to do so may
impair the integrity of these devices.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
The ELO-16 GB Dry Pendent Sprinklers
must only be installed in fittings that
meet the requirements of the Design
Criteria section.
General
Description
The Central Model ELO-16 GB, 11.2
K-factor Standard Response Extended
Coverage Ordinary Hazard, Dry
Pendent Sprinklers are decorative glass
bulb automatic sprinklers designed for
use
where pendent sprinklers are
required on dry pipe systems that are
exposed to freezing temperatures
(e.g. sprinkler drops from unheated
portions of buildings), or
where sprinklers and/or a portion of
the connecting piping may be
exposed to freezing temperatures
(e.g. sprinkler drops from wet
systems into freezers), or
where pendent sprinklers are used on
systems that are seasonably drained
to avoid freezing (e.g. vacation resort
areas).
The ELO-16 GB Dry Pendent Sprinklers
are available in a wide range of
operating temperatures and order
lengths.
The ELO-16 GB Dry Pendent Sprinklers
are listed for use in ordinary hazard
occupancies, with a standard response
thermal sensitivity at spacings up to 16'
x 16' (4,9 x 4,9 m). When used in
ordinary hazard occupancies, the ELO-
16 GB Dry Pendent Sprinklers may be
installed in unobstructed and non-
combustible obstructed construction.
The ELO-16 GB Dry Pendent Sprinklers
are intended for use in fire sprinkler
systems designed in accordance with
the standard installation rules recog-
nized by the applicable Listing or
Approval agency (e.g., UL Listing is
based on NFPA 13 requirements). They
OBSOLETE

The Model ELO-16 GB Dry Pendent
Sprinklers are UL and ULC Listed & NYC
Approved (MEA 120-97-E) as standard
response sprinklers for use in ordinary
hazard occupancies, in accordance with
current NFPA standards and the design
parameters set forth in Table 1 of this
Data Sheet.
The minimum lateral spacing between the
ELO-16 GB Dry Pendent Sprinkers, to
prevent cold soldering, is 14'-4" (4.34 m).
The ELO-16 GB Dry Pendent Sprinklers
are to be installed in the 1 inch NPT outlet
of a malleable iron threaded tee fitting per
ANSI B16.3 or cast iron threaded tee
fitting per ANSI B16.4 with the end
sprinkler fitting on a branch line to be
plugged as shown in Figure 3. Only use
maximum 2-1/2 inch size reducing tee's
for dry pipe sprinkler systems.
NOTES
Do not install the ELO-16 GB Dry Pendent
Sprinklers into any other type fitting
without first consulting the Technical
Services Department. Failure to use the
appropriate fitting may result in: failure of
the sprinkler to properly operate due to
formation of ice over the inlet Plug or
binding of the inlet Plug; or, insufficient

The ELO-16 GB Dry Pendent Sprinkers
must be installed in accordance with the
following instructions:
NOTES
The ELO-16 GB Dry Pendent Sprinkers
must only be installed in fittings that meet
the requirements of the Design Criteria
section.
Refer to the Design Criteria section for
other important requirements regarding
piping design and sealing of the clearance
space around the Main Tube.
Installation
engagement of the inlet pipe threads with
consequent leakage.
In the case of a dry pipe sprinkler system
subject to freezing, the use of a fitting of
other than the types specified may result
in failure of the sprinkler to properly
operate due to the formation of ice over
the Inlet.
Branch, cross, and feed main piping
connected to Dry Sprinklers and subject to
freezing temperatures must be pitched for
drainage in accordance with the minimum
requirements of the National Fire
Protection Association for dry pipe
sprinkler systems.
When Dry Sprinklers are to be used in wet
pipe sprinkler systems protecting areas
subject to freezing temperatures (e.g.,
sprinkler drops into freezers), consider-
ation must be given to the appropriate
length of the sprinkler that will prevent
freezing of the water in the connecting
pipes due to conduction.
When Dry Sprinklers penetrate a ceiling
into an area subject to freezing, the
clearance space around the Main Tube
must be completely sealed in order to
prevent the leakage of moist air into the
freezing area which might result in the
formation of condensate around the
Frame, Deflector, Bulb Seat, or Bulb.
Failure to prevent the formation of
condensate could result in the build-up of
ice around the releasing components and,
consequently, either an inadvertent
operation of the sprinkler or impaired
operation due to reduced thermal
sensitivity.

Step 2. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 3. Wrench tighten the sprinkler by
wrenching on the Main Tube with a pipe
wrench whenever the casing is readily
accessible. Otherwise, use a W-Type 8
Sprinkler Wrench (Ref. Figure 3). The
wrench recess of the W-Type 8 is to be
applied to the sprinkler wrench flats (Ref.
Figure 1 & 2).
Step 4. After a suspended ceiling has
been installed or the finish coat has been
applied to a fixed ceiling (as applicable),
slide on the outer piece of the Escutcheon
until it comes in contact with the ceiling.
Do not lift the ceiling panel out of its
normal position.
Do not install any bulb type sprinkler if the
bulb is cracked or there is a loss of liquid
from the bulb. With the sprinkler held
horizontally, a small air bubble should be
present. The diameter of the air bubble is
approximately 1/16 inch (1,6 mm) for the
155
° F/68 ° C to 3/32 inch (2,4 mm) for the
286
° F/141 ° C rating.
A leak tight 1 inch NPT sprinkler joint
should be obtained with a torque of 20 to
30 ft.lbs. (26,8 to 40,2 Nm). Higher levels
of torque may distort the 1 inch NPT
sprinkler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.

The ELO-16 GB Dry Pendent Sprinklers
must be maintained and serviced in
accordance with the following instructions.
NOTES
Absence of the outer piece of an escutch-
eon, which is used to cover a clearance
hole, may delay the time to sprinkler
operation in a fire situation.
Before closing a fire protection system
main control valve for maintenance work
on the fire protection system which it
controls, permission to shut down the
affected fire protection systems must be
obtained from the proper authorities and
all personnel who may be affected by this
action must be notified.
It is recommended that the piping
connected to Dry Sprinklers be periodi-
cally checked to assure that proper pitch
and drainage is in accordance with the
minimum requirements of the National
Fire Protection Association if the piping is
subject to freezing temperatures.
A Vent Hole is provided in the Bulb Seat
(Ref. Figure 4) to indicate if the Dry
Sprinkler is remaining dry. Evidence of
leakage from the Vent Hole is an indica-
tion that there may be weepage past the
O-ring seal and, therefore, it is an
indication that the sprinkler needs to be
removed for determining the cause of
leakage (e.g. an improper installation or an
ice plug). The fire protection system
control valve must be closed and the
system drained before removing the
sprinkler.
Sprinklers which are found to be leaking or
exibiting visible signs of corrosion must be
replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
tures will exceed 100°F/38°C and they
must never be painted, plated, coated or
otherwise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced if
they cannot be completely cleaned by
wiping the sprinkler with a cloth or by
brushing it with a soft bristle brush.
Care must be exercised to avoid damage
- before, during, and after installation.
Sprinklers damaged by dropping, striking,
wrench twist/slippage, or the like, must be
replaced. Also, replace any sprinkler that
has a cracked bulb or that has lost liquid
from its bulb (ref. Installation Section).
