Product Description
The Reliable Model KFR-CCS Combustible Concealed
Space Sprinkler is an upright, special sprinkler designed to
provide protection of specific light hazard combustible and
noncombustible concealed spaces requiring sprinkler protection.
The Model KFR-CCS Sprinkler utilizes a fast response solder-
link fusible element that has demonstrated response times in
laboratory tests which are five to ten times faster than standard
response sprinklers. This feature enables the sprinkler to apply
water to a fire much faster than standard response sprinklers of
the same temperature rating.
Application
The Model KFR-CCS sprinkler is specifically listed for the
protection of horizontal combustible concealed spaces up to 36”
deep as described in NFPA 13 and as detailed in this bulletin.
In addition, the Model KFR-CCS sprinkler is specifically listed for
the protection of horizontal combustible concealed spaces with
wood truss and bar joist construction up to and including 60”
(900 mm) deep.
Installation
Model KFR-CCS Sprinklers are to be installed in the upright
position with their frames arms parallel to the pipe. When
installing the Model KFR-CCS sprinkler use only the Reliable
Model W2 installation wrench. Usage of any other type of
installation wrench may damage the sprinkler and will void
the manufacturer’s warranty. Damaged sprinklers must be
immediately replaced. A leak tight ½” NPT (R1/2) sprinkler joint
can be obtained with an installation torque of approximately 8 -18
ft-lbs (10.8 – 24.4 N
.
m) after application of an appropriate thread
sealant. Do not tighten sprinklers over these recommended limits.
Doing so may cause leakage and/or premature operation.

Maintenance
Reliable Model KFR-CCS series sprinklers 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.
Replace any sprinkler which has been painted (other than factory
applied). A stock of spare sprinklers should be maintained to
allow quick replacement of damaged or operated sprinklers.
Failure to properly maintain sprinklers may result in inadvertent
operation or non-operation during a fire event.
