Product Description
The Reliable Model G4 XLO-QR ECLH/ECOH Concealed
sprinkler is an Extended Coverage Sprinkler for use in Light
Hazard and Ordinary Hazard occupancies with a coverage
area of up to 400 square feet (37.2 m2) per sprinkler.
The use of extended coverage sprinklers can provide lower
installation costs by requiring fewer sprinklers, less piping and
reduced labor. The larger K-factor 11.2 (160 metric) provides
for reduced pressures to achieve the required flow compared
with smaller K-factor sprinklers.
The G4 XLO-QR ECLH/ECOH can eliminate the need for
precise cutting of drop nipples. The Push-on/Thread-off cover
plate assembly provides up to 1/2” (13 mm) of adjustment to
allow the cover to fit accurately against the ceiling. The fire
protection system need not be shut down when adjusting or
removing the Push-on/Thread-off cover plate assembly.

Design Criteria
G4XLO-QR ECLH/ECOH sprinklers are to be installed ac-
cording to the design criteria shown in this Bulletin, NFPA 13,
and all other local codes and ordinances. Flows and pres-
sures, as shown in the Flow Requirements chart on page 2
of this Bulletin, must be selected based on the spacing and
hazard classifications.
The following criteria also apply:
• Minimum sprinkler spacing is 9 ft (2.75 m).
• Sprinklers have a minimum flow requirement for each
spacing as shown in the Flow Requirements chart on
page 2.
• Sprinklers are only to be used in systems hydraulically
designed per NFPA 13.
• Deflector to commodity clearance shall be a minimum
of 18 inches (457 mm).
• Sprinklers shall be installed in unobstructed construc-
tion as defined in NFPA 13.
• Sprinklers can be installed under a sloping ceiling not
exceeding 2 inches (50.8 mm) of rise in 12 inches
(304.5 mm).
• Maximum working pressure is 175 psi (12.1 bar) at the
sprinkler.

Installation
Do not install the MODEL G4
XLO-QR ECLH/ECOH in ceilings
which have positive pressure in
the space above. After installa-
tion, inspect all sprinklers to en-
sure that both the gap between
the cover plate and ceiling and
the 4 drive slots in the cup are
open and free from any air flow
impediment.
After a 25 /
8” (67 mm) diameter
hole is cut in the ceiling, the
Maintenance
Model G4XLO-QR ECLH/ECOH sprinklers should be in-
spected and maintained in accordance with NFPA 25. Do
not clean sprinklers with soap and water, ammonia or any
other cleaning fluids. Remove dust by using a soft brush
or gentle vacuuming. Replace any sprinkler or cover plate
assembly, which has been painted (other than factory ap-
plied) or damaged in any way. A stock of spare sprinklers
should be maintained to allow quick replacement of dam-
aged or operated sprinklers. Prior to installation, sprin-
klers should be maintained in their original cartons and
packaging until used to minimize the potential for damage
to sprinklers that would cause improper operation or non-
operation. Once operated automatic sprinklers and cover
plates cannot be reassembled and reused. New sprin-
klers of the same size, type and temperature rating must
be installed. A cabinet of replacement sprinklers should
be provided for this purpose.
Model G4 Wrench
sprinkler is to be installed with the Model G4 Wrench.
When installing a sprinkler, the wrench is first positioned
into the sprinkler/cup assembly until two wrench tangs
fully engage drive slots in the top of the cup. The sprin-
kler is then tightened into the pipe fitting. When inserting
or removing the wrench from the sprinkler/cup assembly
care should be taken to prevent damage to the sprin-
kler. DO NOT WRENCH ON ANY OTHER PART OF THE
SPRINKLER/CUP ASSEMBLY.
A protective cap is provided to protect the drop down
deflector from damage which could occur during con-
struction before the cover plate is installed. The cap is
factory installed inside the sprinkler cup. Remove the
cap to install the sprinkler, then replace the cap until the
cover plate is installed.
THE MODEL G4 XLO-QR ECLH/ECOH SPRINKLER
MUST BE INSTALLED ONLY WITH A 135°F RATED
MODEL G4/G5 COVER PLATE WHICH HAS BEEN
LISTED WITH THE SPRINKLER.
