standard corrosion tests of the
applicable approval agencies, the
testing is not representative of all
possible corrosive atmospheres.
Consequently, it is recommended that
the end user be consulted with respect
to the suitability of these corrosion
resistant coatings for any given
corrosive environment. The effects of
ambient temperature, concentration of
chemicals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will
be exposed.
Operation:
Model ELO-231 - A fusible alloy is
sealed into a bronze actuating rod
(center strut) by a stainless steel ball.
When the alloy melts at its rated
temperature, the ball is forced upward
into the center strut, releasing the two
ejectors and operating the sprinkler.
Model ELO-231 BV & ELO-231 BVQR -
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, which then allows the
sprinkler to activate & flow water.
WARNINGS
The Model ELO-231, ELO-231 BV &
ELO-231 BVQR Intermediate Level
Sprinklers described herein must be
installed and maintained in compli-
ance with this document, as well as
with the applicable standards of the
National Fire Protection 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.

General
Description
The Central Model ELO-231, ELO-231
BV & ELO-231 BVQR, 11.2 K-factor
Upright & Pendent Intermediate Level
Automatic Sprinklers are designed for
use in sprinkler systems having
sprinklers at multiple elevations in the
same area. Intermediate Level
Sprinklers are primarily designed for
use in rack storage sprinkler systems,
where their thermally sensitive
elements must be sheilded from the
water spray of higher elevation
sprinklers which could operate earlier
during a fire. Intermediate Level
Sprinklers are also used in applica-
tions such as beneath open gridded
catwalks.
The upright version of the Intermedi-
ate Level Sprinkler is created using an
upright Model ELO-231, ELO-231 BV
or ELO-231 BVQR Standard Spray
Sprinkler and a separate head guard/
water sheild assembly (WSG-2). The
pendent version is created using a
pendent Model ELO-231, ELO-231 BV
or ELO-231 BVQR Standard Spray
Sprinkler and a separate water sheild
(WS-2) that is threaded on the 3/4"
NPT of the sprinkler prior to installing
the sprinkler into the fitting.
If there is a possibility that the Model
ELO-231, ELO-231 BV or ELO-231
BVQR Standard Spray Sprinkler may
be exposed to mechanical damage, a
head guard assembly (G-2) can be
added to the Sprinkler.
These sprinklers are available with
wax, lead, or polyester coatings, as
applicable. These coatings may be
utilized to extend the life of copper
alloy sprinklers beyond that which
would otherwise be obtained when
exposed to corrosive atmospheres.

Installation
The Model ELO-231, ELO-231 BV &
ELO-231 BVQR Intermediate Level
Automatic Sprinklers
must be installed
in accordance with the following
instructions.
NOTES
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

rating.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 ft.lbs. (9,5 to 19,0 Nm). A maximum
of 21 ft.lbs. (28,5 Nm) of torque is to be
used to install 1/2 inch NPT sprinklers.
A leak tight 3/4 inch NPT sprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). A
maximum of 30 ft.lbs. (40,7 Nm) of
torque is to be used to install 3/4 inch
NPT sprinklers. Higher levels of torque
may distort the sprinkler inlet with
consequent leakage or impairment of
the sprinkler.
If the wax coating on a wax coated
sprinkler is damaged during installation,
refer to Data Sheet 3-7.0 or 3-8.0 for
guidelines on the proper repair
proceedures.
Upright Sprinklers
Step 1. Upright sprinklers must be
installed only in the upright position. The
deflector is to be parallel to the ceiling,
roof, or mounting surface, as applicable.
Step 2. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 3
Sprinkler Wrench (Ref. Fig. 3). The W-
Type 3 Sprinker Wrench is to be applied
to the wrench
Pendent Sprinklers
Step 1. Pendent sprinklers must be
installed only in the pendent position.
The deflector is to be parallel to the
ceiling, roof, or mounting surface, as
applicable.
Step 2. If applicable, thread the WS-2
Water Shield onto the sprinkler threads
with the stamped marking toward the
deflector and just to the end of the
threads. There should be an 1/8 inch
(3,2 mm) gap between the plate and the
Sprinkler Wrench Flat.
Step 3. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 4. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 3
(Ref. Fig. 3). The Combination Wrench
is to be applied to the wrench flats only.
Step 5. Rotate the WS-2 Water Shield
clockwise (looking up) so that it
engages with the sprinkler threads.
Head Guards
Step 1. After the sprinkler has been
installed, gently spread the two base
sections of the G-2 or WSG-2 Head
Guard and slide the guard around the
sprinkler head so the base of the guard
is located between the sprinkler threads
and the wrench flats of the sprinkler.
Step 2. Fasten the two horizontal
retaining clips (Ref. Fig 1 & 2) in place,
over the proper vertical rib of the guard.
Make sure this action results in a tight fit
between the clip and the rib. If not, bend
the clip slightly and repeat the proce-
dure until a tight fit is obtained.
Step 3. If installing the G-2 Head Guard
on a pendent sprinkler with the WS-2
Water Shield, turn the water shield
clockwise on the sprinkler thread until it
"bottoms out" against the base of the
wire guard.

Products
The Model ELO-231, ELO-231 BV &
ELO-231 BVQR Intermediate Level
Sprinklers
must be maintained and
serviced in accordance with the
following instructions.
NOTES
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system it
controls, permission to shut down the
affected fire protection systems must be
obtained from the proper authorities. All
personnel who may be affected by this
action must be notified.
Sprinklers which are found to be leaking
or exhibiting 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 or overheated solder
type sprinklers must be replaced. Glass
bulb 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).
Frequent visual inspections are
recommended to be initially performed
for wax, lead, and/or polyester coated
sprinklers, after the installation has
been completed, to verify the integrity of
the wax and/or lead coating. Thereafter,
annual inspections per NFPA 25 should
suffice; however, instead of inspecting
from the floor level, a random sampling
of close-up visual inspections should be
made, so as to better determine the
exact sprinkler condition and the long
term integrity of the wax, lead, and/or
polyester coating, as it may be affected
by the corrosive conditions present.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards of
the National Fire Protection Association
(e.g., NFPA 25), in addition to the
standards of any other authorities
having jurisdiction. The installing
contractor or sprinkler manufacturer
should be contacted relative to any
questions.
