Product Description
Model F3QR56 Dry sprinklers are quick-response, stan-
dard coverage sprinklers with a nominal K-Factor of 5.6 (80
metric). Available in Dry Pendent or Dry Horizontal Sidewall
configurations, Model F3QR56 Dry sprinklers all use a 3 mm
glass bulb operating element. See the Temperature Rat-
ings table in this Bulletin for available temperature ratings.
Model F3QR56 Dry sprinklers are intended for installation
on wet-pipe, dry-pipe, or preaction sprinkler systems in ac-
cordance with NFPA 13, FM Property Loss Prevention Data
Sheets, and other applicable installation standards.
Model F3QR56 Dry sprinklers are available with a vari-
ety of escutcheon options as illustrated in Figs. 1 through
3 and Figs. 5 through 9. In addition, Model F3QR56 Dry
Pendent sprinklers are also available with the Model CCP
conical concealed cover plate as illustrated in Fig. 4. Avail-
able sprinkler, escutcheon, and cover plate finishes are
identified in the Finishes table in this Bulletin. The Model F1
escutcheon, Model FP escutcheon, and Model CCP cover
plate are the only recessed escutcheons and cover plate
listed for use with Model F3QR56 Dry sprinklers; the use of
any other recessed escutcheon or cover plate with Model
F3QR56 Dry sprinklers will void all guarantees, warranties,
listings and approvals.

Inlet fittings are available with 1” NPT, ISO 7-1R1, 3/4” NPT,
or ISO7-1R3/4 threads. Sprinklers with 3/4” NPT and ISO7-
1R3/4 inlet fittings are intended primarily for replacement of
existing 3/4” or ISO7-1R3/4 inlet dry sprinklers, but may also
be used in new installations.

Installation Instructions
Model F3QR56 Dry sprinklers must only be installed in the
following fittings:
1. The side outlet of an ANSI B 16.3 class 150 (malleable
or ductile) or ANSI B16.4 class 125 (cast) iron pipe
tee
2. The run outlet of an ANSI B 16.3 class 150 (malleable
or ductile) or ANSI B16.4 class 125 (cast) iron pipe
tee, with the side outlet plugged (wet-pipe systems
only)
3. Spears Manufacturing Company Brass Thread In-
sert Style or Special Reinforced Plastic Thread Style
Listed adapter or tee (wet-pipe systems only) (gasket
sealed outlets shall not be used)
4. Any Listed CPVC sprinkler adapter or tee only in ac-
cordance with Fig. 11 and upon verification that the
CPVC adapter or tee does not interfere with the sprin-
kler’s inlet (wet-pipe systems only) (gasket sealed
outlets shall not be used)
Model F3QR56 Dry sprinklers must not be installed into el-
bows, welded outlets, or gasket sealed outlets. Installation of
the Model F3QR56 Dry sprinkler is not recommend in cop-
per pipe systems, as this may reduce the life expectancy of
the sprinkler.
In all dry-pipe system installations, the Model F3QR56 Dry
sprinkler must be installed with protrusion into the fitting in
accordance with Fig. 1 through Fig. 9 in this Bulletin. Do not
install Model F3QR56 Dry sprinklers with the standard (long)
inlet fitting into CPVC fittings that have an internal obstruc-
tion (see Fig. 11); this will damage the sprinkler, the fitting,
or both. Model F3QR56 Dry sprinklers are available with a
short “PL” inlet fitting for installation on CPVC fittings of wet-
pipe sprinkler systems only.
Model F3QR56 Dry sprinklers connected to wet-pipe sys-
tems must be installed with the Exposed Minimum Barrel
Length required by Fig. 10 located in a Heated Area.
An orange protective clip is factory installed on the sprin-
kler to protect the glass bulb thermal element from dam-
age. The clip should remain in place during installation of
the sprinkler and be removed when the sprinkler system is
placed in service. Sprinklers with 3/4” NPT and ISO7-1R3/4
inlets are supplied with a protective cap on the inlet that
must be removed before installation.
Use the following steps for installation:
1. Cut a hole in the wall or ceiling directly in-line with
the outlet of the fitting. See the Installation Data table
for the recommended hole diameter based on the es-
cutcheon or cover plate option selected.
2. Apply pipe joint compound or PTFE tape to the male
threads of the sprinkler’s inlet fitting.
3. Install the sprinkler in the fitting using the installation
wrench specified in the Installation Data table. The
Model F3 and F3R wrenches are designed to be in-
serted into the groves in the sprinkler’s wrench boss
as shown in Fig. 12. The Model XLO2 wrench is de-
signed to fit into the cup and engage the wrench boss
as shown in Fig. 13. Do NOT wrench any part of the
sprinkler assembly other than the wrench boss. When
inserting or removing the wrench from the sprinkler,
care should be taken to prevent damage to the sprin-
kler. The sprinkler is then tightened into the pipe fitting
to achieve a leak free connection. The recommended
minimum to maximum installation torque is 22 - 30 lb-
ft (30 – 40 N-m) for 1” NPT and ISO7-1R1 sprinklers,
and 14 - 20 lb-ft (19 – 27 N-m) for 3/4” NPT and ISO7-
1R3/4 sprinklers.
3a.Alternatively, where access to the outer tube of
the sprinkler is available, the Model F3QR56 Dry
sprinkler may be installed using a pipe wrench.
The pipe wrench shall only be permitted to inter-
face with the galvanized steel outer tube portion of
the sprinkler (Item #8 in Fig. 16). Do NOT wrench
any other portion of the sprinkler assembly. A pipe
wrench can install the sprinkler into the fitting with
a large amount of torque; consideration should be
given to the need for future removal of the sprin-
kler because the installation torque will have to be
matched or exceeded to remove the sprinkler. The
recommended minimum to maximum installation
torque is 22 - 30 lb-ft (30 – 40 N-m) for 1” NPT
and ISO7-1R1 sprinklers, and 14 - 20 lb-ft (19 – 27
N-m) for 3/4” NPT and ISO7-1R3/4 sprinklers.
4. Standard and Model HB escutcheons can be in-
stalled by slipping the escutcheon over the can until
the escutcheon is seated against the ceiling or wall.
Model F1 escutcheons are installed by pressing the
escutcheon onto the collar until the escutcheon is
seated against the ceiling or wall. The Model FP es-
cutcheon is installed by pressing or threading the es-
cutcheon into the cup by hand; the escutcheon can
be tightened against the ceiling or wall by turning the
escutcheon in a clockwise direction and removed by
turning the escutcheon in a counter-clockwise direc-
tion. To install the Model CCP cover plate, first remove
the protective clip. Install the Model CCP cover plate
on the sprinkler by pressing or threading the cover
plate into the cup by hand; the cover plate can be
tightened against the ceiling by turning the cover
plate in a clockwise direction and removed by turning
the cover plate in a counter-clockwise direction.
5. Remove the orange protective clip when placing the
sprinkler system in service.

Maintenance
The Model F3QR56 Dry Sprinklers should be inspected
and the sprinkler system maintained in accordance with
NFPA 25. Do not remove the factory applied thermally sen-
sitive wax fillet between the bulb supporting cup and the
wrenching boss. Do not replace this wax with a substitute
substance.
An Alternate substance may interfere with proper operation
of the sprinkler. Do not clean sprinklers with soap and water,
ammonia or any other cleaning fluids. Remove dust by us-
ing a soft brush or gently vacuuming. Replace any sprin-
kler which has been painted (other than factory applied) or
damaged in any way. A stock of spare sprinklers should be
maintained to allow quick replacement of damaged or op-
erated sprinklers. Prior to installation, sprinklers should be
maintained in the original cartons and packaging until used
to minimize the potential for damage to sprinklers that would
cause improper operation or non-operation.
