Product Description
The Reliable Model GXLO sprinkler is a center strut, solder
in compression, extra large orifice sprinkler that has been de-
signed for storage and non-storage applications. The Model
GXLO sprinkler is available in either an upright or pendent con-
figuration. The Model GXLO sprinkler is available with either
3/4-inch NPT or ISO 7-R3/4 threads. The Model GXLO Upright
is optionally available with either 1/2-inch NPT or ISO 7-R1/2
threads for retrofit applications only.
Design Criteria
The Model GXLO sprinkler is intended for use as a standard
response standard spray sprinkler in hydraulically designed
sprinkler systems with a minimum pressure of 7 psi (0.5 bar) in
accordance with the area/density curves of NFPA 13 or in ac-
cordance with FM Property Loss Prevention Data Sheets.
The Model GXLO sprinkler is not a “Large Drop” or “ESFR”
sprinkler.

Installation
Reliable’s Model GXLO sprinkler must be installed according
to NFPA Standards or the appropriate Factory Mutual Loss Pre-
vention Data Sheets for all area/density methods of design as
well as requirements of the Authority Having Jurisdiction.
Model GXLO sprinklers must be installed with the Reliable
Model H sprinkler wrench. Any other type of wrench may dam-
age the sprinkler.
A leak tight joint should be obtained with a torque of 14 to
20 lb-ft (19 to 27 N-m) for ¾-inch NPT and ISO 7-R¾ thread
sprinklers. For ½-inch NPT and ISO 7-R½ thread sprinklers the
recommended installation torque is 8 to 18 lb-ft (11 to 24 N-m).
Do not tighten sprinklers over the maximum recommended in-
stallation torque, because it may cause leakage or impairment
of the sprinklers.

Maintenance
Model GXLO Sprinklers should be inspected and the sprinkler
system 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 which has been painted (other than fac-
tory applied) or damaged in any way. A stock of spare sprinklers
should be maintained to allow quick replacement of damaged
or operated sprinklers. Prior to installation, sprinklers should be
maintained in the original cartons and packaging until used to
minimize the potential for damage to sprinklers that would cause
improper operation or non-operation.
