General
Description
The 11.2 K-factor, Series ELO-231,
Standard Response, Standard Cover-
age, Upright and Pendent Sprinklers
(Ref. Figure 1) are automatic sprin-
klers of the fusible solder type. They
are “standard response - spray sprin-
klers” that produce a hemispherical
water distribution pattern below the
deflector.
The 11.2 K-factor, ELO-231 Sprinklers
were subjected to full scale, high-piled
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 storage.
Higher flow rates can be achieved at
much lower pressures with the 11.2
K-factor, ELO-231 Sprinklers — mak-
ing 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 copper alloy com-
ponentsusedinSeriesELO-231sprin-
klers beyond that which would other-
wise be obtained when exposed to
corrosive atmospheres. Although wax
and lead coated sprinklers have
passed the standard corrosiontests of
the applicable approval agencies, the
testing is not representative of all pos-
sible corrosive atmospheres. Conse-
quently, it is recommended that the
end user be consulted with respect to
the suitability of these corrosion resis-
tant coatings for any given corrosive
environment. The effects of ambient
temperature, concentration of chemi-
cals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemicalto which thesprinklerswill be
exposed.
An upright intermediate level version
of the Series ELO-231 Sprinklers for
in-rack applications can be obtained
by utilizing the Series ELO-231 Up-
right Sprinkler with the WSG-2 Guard
& Shield, and a pendent intermediate
level version of the Series ELO-231
Sprinklers can be obtained by utiliz-
ing the Series ELO-231 Pendent
Sprinklerwith theWS-2Shield.If there
is a possibility of the pendent interme-
diate level version being exposed to
mechanical damage, a G-2 Guard can
be added.

Operation
A fusible alloy is sealed into a bronze
actuating rod (center strut) by a stain-
less steel ball. When the alloy melts at
its rated temperature, the ballis forced
upward into the center strut, releasing
the two ejectors and operating the
sprinkler.
Installation
The Series ELO-231 Sprinklers must
be installed in accordance with the fol-
lowing instructions:
NOTES
A leak tight 3/4 inch NPTsprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). A maxi-
mum 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 ob-
tained 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 con-
nections. Higher levels of torque may
distort the sprinkler inlet and cause
leakage or impairment of the sprinkler.
Do not attempt to make-up for insuffi-
cient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Readjust the position of the
sprinkler fitting to suit.
The Series ELO-231 Upright and
Pendent Sprinklers must be installed
in accordance with the following in-
structions.
Step 1. Pendent sprinklers are to be
installed in the pendent position, and
upright sprinklers are to be installed in
the upright position.
Step 2. With pipe thread sealant ap-
plied 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 flats.
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
bare metal to the corrosive environ-
ment. The jaws of the wrench should
be opened sufficiently wide to pass
over the wrench flats without damag-
ing the wax coating. Before wrench
tightening the sprinkler, the jaws of the
wrench are to be adjusted to just con-
tact the sprinkler wrench flats. After

the wrench jaws before removing the
wrench.
After installation, the sprinkler wrench
flats and frame arms must be in-
spected and the wax coating re-
touched (repaired) whenever the coat-
ing has been damaged and bare metal
is exposed. The wax coating on the
wrench flats can be retouched by gen-
tly 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 ap-
plied to the wrench flats and frame
arms is permitted, and the retouching
is to be performed 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 complete coverage are unsuc-
cessful, additional wax can be 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 rod heated as previously de-
scribed, touch the rod to the area re-
quiring additional wax with the rod an-
gled downward, and then touch the
wax stick to the rod approximately
one-half inch away from the area re-
quiring retouching. The wax will melt
and run down onto the sprinkler.
Care and
Maintenance
Series ELO-231 Sprinklers must be
maintained and serviced in accord-
ance with the following instructions:
NOTES
Before closing a fire protection system
control valve for maintenance work on
the fire protection system that it con-
trols, permission to shut down the af-
fected fire protection system must be
obtained from the proper authorities
and all personnelwho may be 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 be
painted, plated, coated or otherwise
altered after leaving the factory. Modi-
fied or over-heated sprinklers must be
replaced.
Care must be exercised to avoid dam-
age to the sprinklers — before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed.
Frequent visual inspections are rec-
ommendedtobeinitiallyperformedfor
corrosion resistant sprinklers,after the
installation has been completed, to
verify the long term potential integrity
of the sprinkler coatings. Thereafter,
annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating, as it may
be affected by the corrosive conditions
present.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer 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.
