General
Description

The 11.2 K-factor, Series ELO-231B,
Standard Response, Standard Cover­age, Upright and Pendent Sprinklers
(Ref. Figure 1) are automatic sprin­klers of the frangible bulb type. They
are “standard response - spray sprin­klers” that produc e a hemispherical
water distribution pattern below the
deflector.

The 11.2 K-factor, ELO-231B Sprin­klersweresubjectedtofullscale,high­piled storage, fire tests to qualify their
use in lieu of 5.6 or 8.0 K-factor stand­ard spray sprinklers for the protection
of high-piled sto ra ge .

Higher flow rates can be achieved at
much lower pressures with the 11.2
K-factor, ELO-231B Sprinklers —
making their use highly advantageous
in high density applications, such as
the protection of high-piled storage.

Wax or lead coatings can be used to
extend the life of the copperalloy com­ponents used in Series ELO-231B
sprinklers beyond that which would
otherwise be obtained when exposed
to corr osiv e atmospheres. Although
wax, lead, and polyester coated sprin­klers have passed the standard corro­sion tests of the applicable approval
agencies, the testing is not repre-

IMPORTANT

Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal­lation of sprinkler systems and com­ponents. Improper handling and in­stallation can permanently damage
a sprinkler system or its compo­nents and cause the sprinkler to fail
tooperateinafiresituationor cause
it to operate prematurely.

mospheres.Consequently,itisrecom­mendedthattheenduserbe 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 chemicalto which the sprin­klers will be exposed.

An upright intermediate level version
of the Series ELO-231B Sprinklers for
in-rack applications can be obtained
by utilizing the Series ELO-231B Up­right Sprinkler with the WSG-2 Guard
& Shield, and a pendent intermediate
level version of the Series ELO-231B
Sprinklers can be obtained by utiliz­ing the Series ELO-231B Pendent
SprinklerwiththeWS-2Shield.Ifthere
is a possibility of the pendent interme­diate level version being exposed to
mechanical damage, a G-2 Guard can
be added.

WARNINGS

The 11.2 K-factor, Series ELO-231B
Upright and P endent Sprinklers de­scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica­ble standards of the National Fire Pro­tection Association, in addition to the
standardsof any other authorities hav­ing jurisdiction. Failure to do so may

impair the performance of these de­vices.

The owner is responsible for maintain­ing their fire protection system and de­vices in proper operating condition.
The installing contractor or manufac­turer should be contacted with any
questions.

Installation of Series ELO-231B Pen­dent Sprinklers in recessed escutch­eons will void all spr inkler warranties,

fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and water to flow.

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
shouldbe present. The diameter of the

A leak tight 3/4 inch NPT sprinklerjoint
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 sprinklers with
3/4 NPT connections. 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 may be used
to install sprinklers with 1/2 NPT con­nections. Higher levels of torque may
distort the sprinkler inlet and cause
leakageor impairment of the sprinkler.

Do not attempt to make-up for insuffi­cient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Readjust the position of the
sprinkler fitting to suit.

The Series ELO-231B Upright and
Pendent Sprinklers must be installed
in accordance with the following in­structions.

Step 1. Pendent sprinklers a re to be

installed in the pendent position, and
upright sprinklers are to be installed in
the upright position.

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. Figure 2),
except that an 8 or 10 inch adjustable
Crescent wrench is to be used for wax
coated sprinklers. With reference to
Figure 1 , the W-Type 3 Sprinkler
Wrench or the adjustable Crescent
wrench, as applicable is to be applied
to the wrench fla t s .

When installing wax coated sprinklers
with the adjustable Crescent wrench,
additional care needs to be exercised
to prevent damage to the wax coating
on the sprinkler wrench flats or frame
arms and, consequently, exposure of

Page4of6

TFP342

bare metal to the corrosive environ­ment. The jaws of the wrench should
be opened sufficiently wide to pass
over the wrench flats without damag­ing the wax coating. Before wrench
tighteningthe sprinkler, the jaws ofthe
wrench are to be adjusted to just con­tact the sprinkler wrench flats. After
wrenchtightening the sprinkler,loosen
the wrench jaws before removing the
wrench.

After installation, the sprinkler wrench
flats and frame arms must be in­spected and the w ax coating re­touched (repaired) whenever the coat­ing has been damaged and bare metal
is exposed. The wax coating on the
wrench flats can be retouched by gen­tly applying a heated 1/8 inch diameter
steel rod to the areas of wax that have
been damaged, to smooth it back over
areas where bare metal is exposed.

NOTES

Only retouching of the wax coating ap­plied to the wrench flats and frame
arms is permitted, and the retouching
is to be perf or med only at the time of
the initial sprinkler installation.

The steel rod should be heated only to
the point at which it can begin to melt
the wax, and appropriate precautions
need to be taken, when handling the
heated rod, in order to prevent the
installer from being burned.

If attempts to retouch the wax coating
with c omplete coverage are unsuc­cessful, additional wax canbe ordered
in the form of a wax stick (the end of
which is color coded). Only the correct
color coded wax is to be used, and
retouching of wrench flats and frame
arms is only permitted at the time of
initial sprinkler installation. With the
steel r od heated as previously de-

scribed, touch the rod to the area re­quiring additional wax with the rod an­gled downward, and then touch the
wax stick to the rod approximatel y
one-half inch away from the area re­quiring retouching. The wax will melt

and run down onto the sprinkler.

Care and
Maintenance

Series ELO-231B Sprinklers must be
maintained and serviced in accord­ance with the following instructions:

NOTES

Before closing a fire protection system
control valve for maintenance work on
the fire protection system that it con­trols, permission to shut down the af­fected fire protection system must be
obtained from the proper authorities
and all personnel who maybe affected
by this action must be notified.

Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.

Automatic sprinklers must never be
painted, plated, coated or otherwise
altered after leaving the factory. Modi­fied sp rinklers 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 to the sprinklers — before,during,
and after installation. Sprinklers dam­aged by dropping, striking, wrench
twist/slippage, or the like, must be re­placed.Also, replace anysprinklerthat
has a cracked bulb or that has lost
liquid from its bulb (ref. Installation
Section Note).

Frequent visual inspections are rec­ommendedtobeinitiallyperformedfor
corrosionresistantsprinklers,after the
installation has been completed, to
verify the long term potential integrity
of the sprinkler coatings. Thereafter,
annual inspecti ons 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 o f the
corrosion resistant coating, as it may
beaffected by the corrosive conditions
present.

The owner is responsible for the in­spection, testing, and maintenance of
their fire protection system and de­vices in compl ianc e 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.

It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
code.
