3. PRODUCT DESCRIPTION
The Viking Standard Response Dry
Sidewall Sprinkler is a thermosensitive
glass-bulb spray sprinkler, suitable for
use in areas subject to freezing. It is
designed for dry systems and preaction
systems where it is necessary to prevent
water or condensation from entering the
supply nipple before the sprinkler oper-
ates. It may also be installed in spaces
subject to freezing and supplied from a
wet system in an adjacent heated area.
The assembly features a sealed brass inlet
and a durable, threaded steel barrel with an
electrodeposited epoxy base coating. The
sprinkler is of the Model M design with a 5
mm glass bulb and horizontal sidewall de-
flector. The Viking Standard Response Dry
Horizontal Sidewall Sprinkler is available in
several finishes and temperature ratings to
meet design requirements.
The seal at the threaded end of the as-
sembly is held in place by force transmit-
ted from the compression screw, through
the glass bulb and internal parts, onto a
special sealing spring. During fire condi-
tions, the heat-sensitive liquid in the glass
bulb expands, causing the glass to shat-
ter, releasing the internal parts to open the
waterway. Water flowing through the
sprinkler orifice strikes the sprinkler de-
flector, forming a uniform spray pattern to
extinguish or control the fire.
The Viking Standard Response Dry Hor-
izontal Sidewall Sprinkler may be in-
stalled with the barrel exposed (refer to
Figure 4 on page 102 d), or with one of
two escutcheon styles:
•For recessed installations, a recessed
style escutcheon with up to 5/8" (15,8
mm) adjustment (see Figure 1 on page
102 b), is available.
•For standard installations, the sprinkler
is available with an adjustable, sur-
face-mounted escutcheon, finished to
allow up to 2" (50,8 mm) of adjustment
(see Figures 2 and 3 on page 102 c).
Both escutcheon styles slide over the
sprinkler deflector, allowing installation
of the escutcheon after the wall finish is
applied.
Viking Standard Response Dry Horizon-
tal Sidewall Sprinklers are available in
1/4" (6,35 mm) increments for the re-
cessed style, and in ½" (12,7 mm) incre-
ments for the adjustable standard es-
cutcheon style, and the plain barrel
style, installed with no escutcheon.
These sprinklers may be ordered in min-
imum lengths from 1-1/2" (38,1 mm) for
the adjustable standard style, 3" (76,2
mm) for the plain barrel style, and 3-1/4"
(82,5 mm) for the adjustable recessed
style. They have listings and approvals
with a maximum length of 45-1/2" (1 156
mm) for the adjustable standard style*,
47" (1 194 mm) for the plain barrel style*,
and 47-1/2" (1 207 mm) for the adjust-
able recessed style*.
* Lengths over the standard length are available, with
no approvals, on a “made-to-order” basis:
•Recessed Dry HSW up to 65-1/2” (1 664 mm).
•Adjustable Standard Dry HSW up to 63-1/2” (1
613 mm).

5. ORDERING INFORMATION
For proper shipment, specify model, fin-
ish, temperature rating, escutcheon
type, and length (“A” Dimension. Dry
horizontal sidewall sprinklers are or-
dered in specific lengths noted as the “A”
dimension (see Figures 1 through 4).
The “A” dimension is the distance from
the face of the fitting (tee) to the finished
surface of the wall in which it is to be in-
stalled. The dry horizontal sidewall
sprinkler must be ordered and manufac-
tured specifically for one of three styles
of installation: with the adjustable re-
cessed escutcheon (see Figure 1), with
the adjustable standard escutcheon (see
Figures 2 and 3), or with the plain barrel
(see Figure 4). For limits of adjustment for
the recessed escutcheon, see Figure 1.
Details and limits of adjustment for the
standard escutcheon style, with 2" (50,8
mm) of adjustment, are shown in Figure 2.
6. INSTALLATION
WARNING: Viking sprinklers are manu-
factured and tested to meet the rigid re-
quirements of approving agencies. The
sprinklers are designed to be installed in
accordance with recognized installation
standards. Deviation from the standards
or any alteration to the sprinkler after it
leaves the factory including, but not lim-
ited to: painting, plating, coating, or modifi-
cation, may render the sprinkler inopera-
tive and will automatically nullify the ap-
proval and any guarantee made by Viking.
A. Viking sprinklers are to be in-
stalled in accordance with the lat-
est edition of Viking technical
data, the latest standards of NFPA,
FM Global, Loss Prevention Coun-
cil, Assemblee Pleniere, VdS or
other similar organizations, and
also with the provisions of gov-
ernmental codes, ordinances, and
standards, whenever applicable.
The use of dry horizontal sidewall
sprinklers may be limited due to
occupancy and hazard. Refer to
the AHJ prior to installation.
B. Sprinklers must be handled with care.
They must be stored in a cool, dry place
in their original container. Never install
sprinklers that have been dropped,
damaged in any way, or exposed to
temperatures in excess of the maxi-
mum ambient temperature allowed (re-
fer to Table 1). Such sprinklers
should be destroyed. Never install
any glass-bulb sprinkler if the bulb is
cracked or if there is a loss of liquid from
the bulb. If a glass bulb lacks the ap-
propriate amount of fluid, it should be
set aside and returned to Viking (or
an authorized Viking distributor) for
analysis as soon as possible. If the
sprinkler is not returned to Viking, it
should be immediately destroyed.
C. Viking Standard Response Dry Hori-
zontal Sidewall Sprinklers are not in-
tended for use in corrosive environ-
ments. Use only sprinklers listed for
corrosive environments when sub-
ject to corrosive atmospheres.
WARNING: Viking dry sprinklers are
to be installed in the 1" outlet or run of
malleable or ductile iron threaded tee
fittings that meet the dimensional re-
quirements of ANSI B16.3 (Class
150), or cast iron threaded tee fittings
that meet the dimensional require-
ments of ANSI B16.4 (Class 125),
even at branch line ends. The
threaded end of the dry sprinkler is de-
signed to allow the seal to penetrate
and extend into the fitting to a prede-
termined depth. This prevents con-
densation from accumulating and
freezing over the sprinkler seal.
1. DO NOT install the dry sidewall
sprinkler into a threaded elbow,
coupling, or any other fitting that
could interfere with thread penetra-
tion. Such installation will dam-
age the brass seal.
2. DO NOT install the dry sidewall sprin-
kler into a coupling or fitting that will
allow condensation to accumulate
above the seal, when located in an
area subject to freezing.
3. NEVER try to modify the dry horizon-
tal sidewall sprinkler. The sprinklers
are manufactured for specific “A” di-
mensions and cannot be modified.
D. The sprinkler must be installed after
the piping is in place to prevent me-
chanical damage. Keep sprinklers with
protective caps or bulb shields con-
tained within the caps or shields during
installation and testing, and any time
the sprinkler is shipped or handled.
1. Before installing the sprinkler, make
certain the “A” dimension is correct
and the sprinkler is the appropriate
model and style, orifice size, and
temperature rating.

2. Apply a small amount of pipe-joint
compound or tape to the male
threads only, taking care not to al-
low a build-up of compound over the
brass inlet and seal. NOTE: Sprin-
klers with protective caps or bulb
shields must be contained within
the caps or shields before applying
pipe-joint compound or tape.
3. Install the dry sidewall sprinkler on the
piping using the special dry sprinkler
wrench only, while taking care not to
damage the sprinkler. DO NOT use
a pipe wrench on the barrel of the
dry sidewall sprinkler. A pipe wrench
may damage the barrel finish.
4. To install the escutcheon for the ad-
justable standard style dry horizontal
sidewall sprinkler, refer to Figure 3.
E. After installation, the entire sprinkler
system must be tested. The test must
be conducted to comply with the in-
stallation standards.
Make sure the sprinkler has been prop-
erly tightened. If a thread leak occurs,
normally the sprinkler must be re-
moved, new pipe-joint compound or
tape applied, and then reinstalled. This
is due to the fact that when the joint seal
is damaged, the sealing compound or
tape is washed out of the joint.
F. Remove plastic protective sprinkler
caps and bulb shields AFTER the
wall finish work is completed where
the sprinkler is installed and there
no longer is a potential for mechani-
cal damage to the glass bulbs. To re-
move the bulb shields, simply pull the
ends of the shields apart where they are
snapped together. To remove caps,
turn the caps slightly and pull them off
the sprinklers. SPRINKLER CAPS
AND BULB SHIELDS MUST BE RE-
MOVED FROM SPRINKLERS BE-
FORE PLACING THE SYSTEM IN
SERVICE!
G. Wet pipe systems supplying dry hori-
zontal sidewall sprinklers must be
provided with adequate heat. Refer
to appropriate installation standards.
7. MAINTENANCE
NOTICE: The owner is responsible for
maintaining the fire-protection system and
devices in proper operating condition. For
minimum maintenance and inspection re-
quirements, refer to the appropriate NFPA
standard that describes care and mainte-
nance of sprinkler systems. In addition,
the AHJ may have additional mainte-
nance, testing, and inspection require-
ments that must be followed.
A. The sprinklers must be inspected on a
regular basis for signs of corrosion,

mechanical damage, obstructions,
paint, etc. The frequency of inspec-
tions may vary due to corrosive atmo-
spheres, water supplies, and activity
around the device.
B. Sprinklers that have been field painted,
caulked, or mechanically damaged
must be replaced immediately. Sprin-
klers showing signs of corrosion shall
be tested and/or replaced immediately
as required. Installation standards re-
quire sprinklers to be tested and, if nec-
essary, replaced after a specified term
of service. Refer to the installation stan-
dards (e.g., NFPA 25) and the AHJ for
the specified period of time after which
testing and/or replacement is required.
Never attempt to repair or reassemble
a dry sprinkler. Sprinklers that have op-
erated cannot be reassembled or
re-used, but must be replaced. When
replacing sprinklers, use only new
sprinklers.
C. The sprinkler discharge pattern is criti-
cal for proper fire protection. Nothing
should be hung from, attached to, or
otherwise obstruct the discharge pat-
tern. All obstructions must be immedi-
ately removed or, if necessary, addi
-
tional sprinklers installed.
D. When replacing existing sprinklers, the
system must be removed from service.
Refer to the appropriate system de-
scription and/or valve instructions.
Prior to removing the system from ser-
vice, notify all AHJs. Consideration
should be given to employment of a
fire patrol in the effected area.
1. Remove the system from service,
drain all water, and relieve all pres-
sure on the piping.
2. Using the special dry sprinkler
wrench, remove the old sprinkler
and install the new unit. Care must
be taken to ensure that the replace-
ment sprinkler is the proper model
and style, with the appropriate “A”
dimension, orifice size, and temper-
ature rating. Follow instructions in
section 6. INSTALLATION.
3. Place the system back in service and
secure all valves. Check for and re-
pair all leaks.
E. Sprinkler systems that have been
subjected to fire must be returned to
service as soon as possible. The en-
tire system must be inspected for
damage, and repaired or replaced as
necessary. Sprinklers that have been
exposed to corrosive products of
combustion or high ambient temper-
atures, but have not operated, should
be replaced. Refer to the AHJ for
minimum replacement requirements.
