Product Description
The Reliable Model G6-80 Concealed Quick Response Ex-
tended Coverage Horizontal Sidewall Sprinkler is an attractive,
concealed sprinkler assembly that utilizes a push-on/pull-off
cover plate assembly. The sprinkler assembly is shipped with
a protective cap.
The flat cover plate is attached to the skirt using 135°F (57°C)
ordinary temperature classication solder. The sprinkler is in-
stalled into the sprinkler tting using the Model G6 Sprinkler
Wrench.
When the ambient temperature rises, the solder holding the
cover plate melts, allowing the release of this part and thus ex-
posing the sprinkler inside to the rising ambient temperature.
The Model G6-80 utilizes a Quick Response soldered link.
Quick-response sprinklers are designed to apply water to a re
sooner than standard-response sprinklers of the same temper-
ature rating.
The Model G6-80 sprinkler is listed for a maximum service
pressure of 175 psi (12,0 bar).
Application and Installation
The Model G6-80 sprinkler is intended for installation in light
hazard occupancies in accordance with NFPA 13. This sprin-
kler is especially well-suited for use in non-corrosive environ-
ments in student dormitories, hotels, hospitals and care facili-
ties.
Model G6-80 Concealed Horizontal Sidewall sprinklers utilize
a sprinkler assembly with spring loaded deployable deflector
feature. The assembly is completed by the installation of the
attractive, 135°F (57°C) push-on/pull-off cover plate assembly,
which provides ¼” (6.3mm) of adjustment.
Apply a PTFE - based thread sealant to the sprinkler threads.
After a 2 5/8” (66.7mm) diameter hole is cut in the wall, the
sprinkler is installed and properly oriented with the Model G6
Wrench, as follows:
Do not remove factory installed plastic protective cap since it
is sized to t inside the G6 wrench. Note that the sprinkler can
only mate when the sprinkler’s deflector orientation tab (Fig. 1)
is aligned with wrench’s key-way. The G6 Wrench has a bubble
level pad and TOP to assist the installer in properly orienting
the sprinkler. Final leveling can be done after leak proof joint is
obtained with a minimum to maximum torque of 14 to 20 ft-lbs
(19 to 27 N.m). Do not attempt to compensate for improper
rough in dimensions of tting by over tightening the sprinkler
assembly, but readjust the sprinkler tting instead. Leave the
protective cap on to assure sprinkler protection while the wall is
plastered, wallpapered or painted.
Concealed cover plate/cup assemblies are listed only for use
with specic sprinklers. The use of any other concealed cover
plate/cup assembly with the Model G6-80 Horizontal Sidewall
Sprinkler or the use of this dedicated concealed cover plate as-
sembly on any sprinkler with which it is not specically listed will
void all guarantees, warranties, listings and approvals.

Maintenance
Model G6-80 Concealed Sprinklers should be inspected and
maintained in accordance with NFPA 25. Do not clean sprin-
klers with soap and water, ammonia or any other cleaning flu-
ids. Remove dust by using a soft brush or gentle vacuuming.
Replace any sprinkler or cover plate assembly, which has been
painted (other than factory applied) or damaged in any way. A
stock of spare sprinkler and cover plate assemblies should be
maintained to allow quick replacement of damaged or operated
sprinklers. Prior to installation, sprinklers should be maintained
in their original cartons and packaging until used to minimize
the potential for damage to sprinklers that would cause improp-
er operation or non-operation.
