• Any time copper piping is used in
any part of a fire sprinkler system,
the copper piping must be installed
in conformance with all applica-
ble standards and requirements
for copper piping, including: NFPA
13, 13D, 13R and 25, ASTM B813,
ASTM B828, and Copper Develop-
ment Association (CDA). Any solder-
ing in any part of a sprinkler system,
either internally or externally, must
be done with use of only an ASTM B
813 approved flux. Residual flux must
be thoroughly REMOVED from both
the interior and exterior surfaces of
the piping before installing the sprin-
kler heads. The use of improper flux,
or the failure to thoroughly remove
proper flux, may result in corrosion of
the sprinkler head or stress cracking,
which in turn may cause the sprin-
klers heads to develop leaks, oper-
ate unexpectedly, or not operate
properly.
• Do not allow solvent cement from
CPVC piping installation to get into
the bore of the sprinkler. Dried sol-
vent cement can negatively affect the
operation of the sprinkler by prevent-
ing the flow of water, increasing the
activation pressure of the sprinkler,
and causing deterioration of the seal
from solvent and chlorine attack.
• Use di-electric unions when installing
sprinklers in systems that utilize both
copper and steel piping as galvanic
reactions can occur due to dissimilar
nature of the metals causing leakage
and performance concerns with the
metallic components installed into
the system.
• Dry Type Sprinklers must be installed
in the appropriately sized outlet
or run of malleable or ductile iron
threaded tee fittings that meet the
dimensional requirements of ANSI
B16.3 or cast iron threaded tee fit-
tings that meet the dimensional
requirements of ANSI B16.4 with
the end sprinkler fitting on a branch
line to be plugged. Failure to use the
appropriate fitting may result in: fail-
ure of the sprinkler to properly oper-
ate due to formation of ice over the
inlet Plug or binding of the inlet Plug;
or, insufficient engagement of the
inlet pipe threads with consequent
leakage.
• Branch, cross, and feedmain piping
connected to Dry Type Sprinklers
and subject to freezing tempera-
tures must be pitched for drainage
in accordance with the minimum
requirements of the National Fire
Protection Association for dry pipe
sprinkler systems. Failure to appro-
priately pitch the system piping for
drainage can result in ice formation
at the Dry Type Sprinkler Inlet that
may cause the sprinkler to fail to acti-
vate in a fire or cause the sprinkler to
activate prematurely.
• When Dry Type Sprinklers are to be
used in wet pipe sprinkler systems
protecting areas subject to freezing
temperatures (e.g., sprinkler drops
into freezers), consideration must
be given to the appropriate length of
the sprinkler that will prevent freezing
of the water in the connecting pipes
due to conduction. When the tem-
perature surrounding the wet pipe
sprinkler system is maintained at a
minimum temperature of 40°F (4°C),
the following are the minimum rec-
ommended lengths between the face
of the sprinkler fitting and the out-
side surface of the protected area
(that is, lengths exposed to a min-
imum ambient temperature of 40°F
(4°C): 12 inches (300 mm) when the
temperature within the protected
area is -20°F (-29°C); 18 inches (450
mm) when the temperature within the
protected area is -40°F (-40°C); and
24 inches (600 mm) when the tem-
perature within the protected area
is -60°F (-51°C). For protected area
temperatures between those given
above, the minimum recommended
length from the face of the fitting to
the outside of the protected area
may be determined by interpolating
between the indicated values. Fail-
ure to provide sufficient length may
cause the sprinkler to fail to activate
in a fire or cause the sprinkler to acti-
vate prematurely.
• When Dry Type Sprinklers penetrate
a ceiling or wall into an area sub-
ject to freezing, the clearance space
around the Sprinkler Casing must be
completely sealed in order to pre-
vent the leakage of moist air into the
freezing area which might result in
the formation of condensate around
the Frame, Deflector, Bulb Seat, or
Bulb. Failure to prevent the forma-
tion of condensate could result in
the build-up of ice around the releas-
ing components. This could result in
inadvertent operation of the sprinkler
or impaired operation due to reduced
thermal sensitivity.

Packaging Sheet’ that is enclosed
