*CAUTION*
RELIABLE DRY PENDENT AND DRY HORIZONTAL SIDEWALL SPRINKLERS MAY BE INSTALLED IN A LISTED
CPVC SPRINKLER FITTING, ONLY UPON VERIFICATION THAT THE FITTING DOES NOT INTERFERE WITH THE
SPRINKLERS INLET.
Do not install dry sprinklers with standard inlets into CPVC fittings that have an internal obstruction; this will damage
the sprinkler, the fitting, or both.
Short inlet (“PL”) versions of Reliable dry sprinklers are available that may or may not be compatible with fittings
having internal obstructions in existing installations. Sprinklers with the short inlet (“PL”) should only be installed in
CPVC fittings of wet‑pipe systems.
In all cases, verify sprinkler and fitting dimensions prior to installation to avoid interference.

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 Insert
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
accordance with Fig. 11 and upon verification that
the CPVC adapter or tee does not interfere with the
sprinkler’s inlet (wet‑pipe systems only) (gasket sealed
outlets shall not be used)
Model F3QR56 Dry sprinklers must not be installed into
elbows, welded outlets, or gasket sealed outlets. Installation
of the Model F3QR56 Dry sprinkler is not recommend in
copper 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 obstruction
(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
systems 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 sprinkler
to protect the glass bulb thermal element from damage. 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 ISO 7‑1R
3/4inlets
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 escutcheon
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 inserted into
the groves in the sprinkler’s wrench boss as shown
in Fig. 12. The Model XLO2 wrench is designed 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 sprinkler. 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 ISO 7‑1R1 sprinklers, and 14‑20 lb‑ft (19 –
27 N‑m) for 3/4" NPT and ISO 7‑1R
3/4sprinklers.
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 interface
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 sprinkler
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
ISO 7‑1R1 sprinklers, and 14‑20 lb‑ft (19 – 27 N‑m)
for 3/4" NPT and ISO 7‑1R
3/4sprinklers.
4. Standard and Model HB escutcheons can be installed
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 escutcheon is installed
by pressing or threading the escutcheon 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 direction. 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
sensitive 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 using a soft brush or gently vacuuming. Replace any
sprinkler 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
operated 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.
