Product Description
Model G5 series sprinklers are standard coverage, flat plate
concealed sprinklers designed for installation in accordance with
NFPA 13 and FM Global Property Loss Prevention Data Sheets. All
Model G5 series sprinklers use a fusible-link operating element.
The sprinklers are offered with a standard Model G5 cover plate,
a Model G5 cover plate with a quick-response (QR) gasket, or a
Model G5 cover plate with a standard-response (SR) gasket. Model
G5 sprinklers with a gasketed cover plate are intended for use in

Installation
Model G5 series sprinklers are intended to be installed in
accordance with NFPA 13, FM Global Property Loss Prevention
Data Sheets, and the requirements of applicable authorities
having jurisdiction. Model G5 series sprinklers must not be
installed in ceilings with positive pressure in the space above.
Ensure that the 4 slots in the cup are open and unobstructed
following installation.
Model G5 series sprinklers are shipped with a wrench-able
protective cap that should remain on the sprinkler until the
sprinkler system is placed in service following construction.
Model G5 series sprinklers can be installed without removing
the wrench-able protective cap using the Model W3 wrench.
Alternatively, Model G5 series sprinklers can be installed using
the Model FC wrench by temporarily removing the protective cap
during installation of the sprinkler. The use of any other wrench
to installed Model G5 series sprinklers is not permitted and may
damage the sprinkler.
Bulletin 034

Replace any sprinkler or cover plate which has been painted (other
than factory applied). Properly installed Model G5 cover plates will
have an air gap that is required for proper operation, do not seal
the gap or paint the cover plates. Model G5 series sprinklers have
holes in the cup that must remain unobstructed.
Replace any sprinkler which has been damaged. A stock of spare
sprinklers should be maintained to allow quick re-placement
of damaged or operated sprinklers. Failure to properly maintain
sprinklers may result in inadvertent operation or non-operation
during a re event.

Ordering Information
Specify the following when ordering.
Sprinkler
• Model [G5-28] [G5-42] [G5-56] [G5-56 300]
[G5-80] [G5-80F]
• Temperature Rating [165°F (74°C)] [212°F (100°C)]
• Threads [NPT or ISO 7-1]

• Model [G5, G5 QR Gasket, G5 SR Gasket]
• Finish (See Table I)
Sprinkler Wrench
• Model W3
• Model FC
P/N 9999970421
Fully insert the Model W3 wrench over the cap until it reaches
the bottom of the cup, or the Model FC wrench over the sprinkler
until the wrench engages the body. Do not wrench any other
part of the sprinkler/cup assembly. The Model W3 and FC
wrenches are designed to be turned with a standard 1/2” square
drive. Tighten the sprinkler into the tting after applying a PTFE
based thread sealant to the sprinkler’s threads. Recommended
installation torque is specied in Table J.
Installation Torque Table J
Sprinkler Threads
Recommended Installation
Torque (min. – max.)
ft.lb N.m
½” NPT or ISO7-1R1/28-18 11-24
¾” NPT or ISO7-1R3/414-20 19-27
Do not exceed the maximum recommended torque. Exceeding the
maximum recommended torque may cause leakage or impairment
of the sprinkler. Use care when inserting or removing the wrench
from the sprinkler to avoid damage to the sprinkler.
Install the cover plate by hand, pushing and then turning the cover
in the clockwise direction until it is tight against the ceiling. For
Model G5 QR Gasket and Model G5 SR Gasket cover plates, the
gasket should be attached to the flange of the cover plate skirt
only. Do not glue the gasket in place or allow the gasket to overlap
both the cover plate and the flange of the skirt.
Maintenance
Reliable Model G5 series sprinkler should be inspected and the
sprinkler system maintained in accordance with NFPA 25, as well
as the requirements of any Authorities Having Jurisdiction.
Prior to installation, sprinklers should remain in the original cartons
and packaging until used. This will minimize the potential for
damage to sprinklers that could cause improper operation or non-
operation.
Do not clean sprinklers with soap and water, ammonia liquid or any
other cleaning fluids. Remove dust by gentle vacuuming without
touching the sprinkler.
