1. DESCRIPTION
Viking Frame Style Spray Nozzles are small, directional spray
nozzles for use on water spray systems. They are thermosensitive
glass bulb style nozzles, however they may be ordered OPEN
(glass bulb and pip cap assembly removed) for use on deluge
systems.
These Frame Style Spray Nozzles are available in various
finishes, temperature ratings, orifice sizes, and spray pattern
discharge angles to meet design requirements. When spraying,
the nozzles discharge a cone-shaped spray pattern. The deflector
determines the included angle of spray pattern discharge. A
special ring provides uniform distribution throughout the spray
pattern.
Other features include the small frame, which allows proper nozzle 60° 90° 120° 150°

DESIGN CRITERIA
(Also refer to the Approval Chart on page 3.)

cULus Listing Requirements:

Frame Style Spray Nozzles are small, directional spray nozzles for use on water spray systems. Refer to the installation standards, such as NFPA 13, for
minimum water supply requirements, nozzle pressure, and installation guidelines.

IMPORTANT: Always refer to Bulletin Form No. F_091699 - Care and Handling of Sprinklers. Viking frame style spray nozzles
are to be installed in accordance with the latest edition of Viking technical data, the appropriate standards of NFPA, FM
Global, LPCB, APSAD, VdS or other similar organizations, and also with the provisions of governmental codes, ordinances,
and standards, whenever applicable.

The Approval Chart on page 3 shows listings and approvals of Frame Style Spray Nozzles for use on water spray systems and
water based deluge systems. The chart shows listings and approvals available at the time of printing. Other approvals are in
process. Check with the manufacturer for any additional approvals.
A. Spray nozzles are to be installed in accordance with the latest edition of Viking technical data, the latest published
standards of NFPA, FM Global, LPCB, APSAD, VdS or other similar organizations, and also with the provisions of
governmental codes, ordinances, and standards whenever applicable. The use of Frame Style Spray Nozzles may be
limited due to occupancy and hazard. Refer to the Authority Having Jurisdiction prior to installation.
B. Frame Style Spray Nozzles are installed on fixed fire protection systems, such as deluge systems, where total flooding is
required.
C. Handle sprinklers and spray nozzles with care. They must be stored in a cool, dry place in their original shipping container.
Never install a sprinkler or spray nozzle that has been dropped, damaged, or exposed to temperatures exceeding the maximum
ambient temperature allowed (refer to Table 1 on page 2).
D. Never install any glass-bulb sprinkler if the bulb is cracked or if there is a loss of liquid from the bulb. A small air bubble should
be present in the glass bulb. Any sprinkler with a loss of liquid from the glass bulb or damage to the fusible element should be
destroyed immediately.
E. Corrosion-resistant sprinklers and spray nozzles must be installed when subject to corrosive atmospheres. When installing
corrosion resistant nozzles, take care not to damage the corrosion resistant coating.
F. Spray nozzles must be installed after the piping is in place to prevent mechanical damage.
G. Sprinklers and spray nozzles must be protected from mechanical damage. Where open sprinklers are used, care must be taken
to prevent foreign materials from entering the orifice. Foreign materials may accumulate and restrict or plug the waterway and
may prevent proper operation of the spray nozzle.
H. Before installing, be sure to have the appropriate sprinkler model and style, with the correct K-Factor, temperature rating, and
response characteristics. When installing automatic (closed) Frame Style Spray Nozzles, proceed to paragraphs I, J, and K below.
1. When installing open Frame Style Spray Nozzles: Hydrostatic testing must be completed prior to spray nozzle installation. Install
plugs in place of spray nozzles for test purposes only. In areas where leakage during testing must be prevented, system piping
may be air tested prior to testing with water. Refer to the appropriate installation standard and the Authority Having Jurisdiction.
When hydrostatic testing is complete, verify that all test plugs have been removed. Proceed to paragraphs I and K below.
Omit paragraph J.
I. For Automatic (closed) and Open Frame Style Spray Nozzles: Before installing, be sure to have the appropriate model and
style, with the correct orifice size, temperature rating, and response characteristics. Frame Style Spray Nozzle deflectors are
identified with the U.S. K-Factor, spray angle, and temperature rating.
1. Apply a small amount of pipe-joint compound or tape to the external threads of the spray nozzle only, taking care not to allow
a build-up of compound inside the inlet.
2. Install the nozzle on the fixed piping, using the special sprinkler/spray nozzle wrench only. Take care not to over-tighten or
damage the spray nozzle operating parts. DO NOT use the deflector to start or thread the unit into a fitting.
J. For automatic (closed) spray nozzle installations: After installation, the entire fixed pipe system must be tested. The test
must be conducted to comply with the installation standards. Make sure the spray nozzle has been properly tightened. If
a thread leak occurs, normally the unit must be removed, 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.
In areas where leakage during testing must be prevented, system piping may be air tested prior to testing with water. Refer to
the appropriate installation standard and the Authority Having Jurisdiction.

K. For Automatic (closed) and Open Frame Style Spray Nozzles: Spray nozzles must be protected from mechanical damage.
Where open spray nozzles are used, care must be taken to prevent foreign materials from entering the orifice. Foreign materials
may accumulate and restrict or plug the waterway and may prevent proper operation of the spray nozzle. Wet pipe systems
must be provided with adequate heat. When installing Frame Style Spray Nozzles on dry systems, refer to the Installation
Guides and the Authority Having Jurisdiction.

5. OPERATION
During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the bulb to shatter, releasing the pip cap and
sealing spring assembly. Water flowing through the orifice strikes the special deflector to direct a specific spray pattern toward the
surface covered.

6. INSPECTIONS, TESTS AND MAINTENANCE

NOTICE
Refer to NFPA 25 for Inspection, Testing, and Maintenance requirements. The owner is responsible for maintaining
the fire protection system and devices in proper operating condition. For minimum maintenance and inspection
requirements, refer to recognized standards such as those produced by NFPA, LPC, and VdS which describe
care and maintenance of sprinkler systems. In addition, the Authority Having Jurisdiction may have additional
maintenance, testing and inspection requirements which must be followed.

A. Sprinklers and spray nozzles must be inspected on a regular basis for corrosion, mechanical damage, obstructions, paint, etc.
Where open spray nozzles are installed, verify that foreign materials (such as dust, dirt, etc.) do not restrict or plug the waterway.
Frequency of inspections may vary due to corrosive atmospheres, water supplies, and activity around the device.
B. Sprinklers or spray nozzles that have been filed painted, caulked, or mechanically damaged must be replaced immediately.
Sprinklers showing signs of corrosion shall be tested and/or replaced immediately as required. Installation standards require
sprinklers to be tested and, if necessary, replaced after a specified term of service. Refer to NFPA 25 and the Authority
Having Jurisdiction for the specified period of time after which testing and/or replacement is required. Never attempt to repair
or reassemble a sprinkler. Sprinklers that have operated cannot be reassembled or re-used, but must be replaced. When
replacement is necessary, use only new sprinklers with identical performance characteristics.
C. The sprinkler discharge pattern is critical for proper fire protection. Therefore, nothing should be hung from, attached to, or
otherwise obstruct the discharge pattern. All obstructions must be immediately removed or, if necessary, additional sprinklers
installed.
D. When replacing existing sprinklers, the system must be removed from service. Refer to the appropriate system description and/
or valve instructions. Prior to removing the system from service, notify all Authorities Having Jurisdiction. Consideration should
be given to employment of a fire patrol in the affected area.
1. Remove the system from service, drain all water, and relieve all pressure on the piping.
2. Use the special sprinkler wrench to remove the old sprinkler by turning it counterclockwise to unthread it from the piping.
3. Install the new sprinkler unit by following the instructions in section 4. INSTALLATION. Care must be taken to ensure
that the replacement sprinkler is the proper model and style, with the correct K-Factor, temperature rating, and response
characteristics. A fully stocked spare sprinkler cabinet should be provided for this purpose.
E. Place the system back in service and secure all valves. Check for and repair all leaks. Sprinkler systems that have been
subjected to a fire must be returned to service as soon as possible. The entire 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
temperatures, but have not operated, should be replaced. Refer to the Authority Having Jurisdiction for minimum replacement
requirements.

USE THE FOLLOWING PRECAUTIONS WHEN HANDLING WAX-COATED SPRINKLERS

Many of Viking’s sprinklers are available with factory-applied wax coating for corrosion resistance. These sprinklers MUST receive
appropriate care and handling to avoid damaging the wax coating and to assure satisfactory performance of the product.
General Handling and Storage of Wax-Coated Sprinklers:
• Store the sprinklers in a cool, dry place (in temperatures below the maximum ambient temperature allowed for the sprinkler temperature rating. Refer
to Table 1 below.)
• Store containers of wax-coated sprinklers separate from other sprinklers.
• Protect the sprinklers during storage, transport, handling, and after installation.
• Use original shipping containers.
• Do not place sprinklers in loose boxes, bins, or buckets.
Installation of Wax-Coated Sprinklers:
Use only the special sprinkler head wrench designed for installing wax-coated Viking sprinklers (any other wrench may damage
the unit).
• Take care not to crack the wax coating on the units.
• For touching up the wax coating after installation, wax is available from Viking in bar form. Refer to Table 1 below. The coating MUST be repaired after
sprinkler installation to protect the corrosion-resistant properties of the sprinkler.
• Use care when locating sprinklers near fixtures that can generate heat. Do not install sprinklers where they would be exposed to temperatures exceed-
ing the maximum recommended ambient temperature for the temperature rating used.
• Inspect the coated sprinklers frequently soon after installation to verify the integrity of the corrosion resistant coating. Thereafter, inspect representative
samples of the coated sprinklers in accordance with NFPA 25. Close up visual inspections are necessary to determine whether the sprinklers are being
affected by corrosive conditions.
