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

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

May 2022

Page 8 of 9

www.reliablesprinkler.com

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]

Cover Plate

• 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.
