The Model G4-300 Concealer®is designed for use where

aesthetic appearance is important. It can be used at work-

ing pressures up to 300 psi (20,7 bar). The Model G4-300

Concealer®is a UL Listed Standard Response Concealed

sprinkler intended for use in accordance with NFPA 13.

Product Description

The Reliable Model G4-300 Concealer®uses the proven

Model G fusible element in a standard style sprinkler frame

with a drop down deflector. This assembly is recessed into

the ceiling and concealed by a flat cover plate. The cover

plate and sprinkler cup assemblies are attached using a

strong threaded engagement. This threaded engagement

provides ½” (13mm) of cover adjustment. The cover plate

is attached to the skirt using an ordinary temperature clas-

sification solder. This result in strong cover plate assembly

with an ordinary temperature rating, and an intermediate

temperature sprinkler which can be installed in 150°F (66°C)

environments. When the temperature at the ceiling rises, the

solder holding the cover plate fuses, allowing the release of

this part and thus exposing the sprinkler inside to the rising

ambient temperature.

Application

The Reliable Model G4-300

Concealer®is a versatile stan-

dard response concealed

sprinkler. It provides the best

form of fire protection while

offering an attractive appear-

ance and ½” (13mm) of cover

adjustment for ease of installation. The small diameter cover

plate is easily and positively attached and blends into the

ceiling, concealing dependable fire protection; an automatic

sprinkler system.

Installation

Refer to Figures 1, 2, and 3

Do not install the G4-300 Concealer®in ceilings which have

positive pressure in the space above.

After a 25/8” (67mm) diameter hole is cut in the ceiling, the

sprinkler is easily installed with the Model G4 Wrench. The

wrench has drive tangs which insert into the cup slots. When

installing a sprinkler the wrench is first positioned into the

sprinkler/cup assembly until the wrench tangs engage the

drive slots in the top of the cup (there are two sets of drive

slots in the cup). The sprinkler is then tightened into the pipe

fitting. When inserting or removing the wrench from the sprin-

kler/cup assembly care should be taken to prevent damage

to the sprinkler. DO NOT WRENCH ON ANY OTHER PART

OF THE SPRINKLER/CUP ASSEMBLY. Final adjustment of

the cover is made by hand turning the cover in the clockwise

direction until it is tight against the ceiling.

A protective cap is provided to protect the drop-down

sprinkler deflector from damage which could occur during

construction before the cover plate is installed. The cap is

factory installed inside the sprinkler cup. Remove cap to

install sprinkler, then re-install cap until the cover plate is in-

stalled.

Maintenance

The Model G4-300 Concealed Sprinklers should be in-

spected 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 any sprinkler

that has been painted (other than factory applied) or dam-

aged in any way. A stock of spare sprinklers should be main-

tained to allow quick replacement of damaged or operated

sprinklers. Prior to installation, sprinklers should be main-

tained in the original cartons and packaging to minimize the

potential for damage to sprinklers that would cause improper

operation or non-operation.

Note: Paint or any other coat-

ings applied over the factory

finish will void all approvals

and warranties.
