Installation Instructions
Model F3QR80 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. 9 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 F3QR80 Dry sprinklers must not be installed into
couplings, elbows, welded outlets, or gasket sealed outlets.
Installation of the Model F3QR80 Dry sprinkler is not recom-
mend in copper pipe systems, as this may reduce the life
expectancy of the sprinkler.
In all dry-pipe system installations, the Model F3QR80 Dry
sprinkler must be installed with protrusion into the fitting in
accordance with Fig. 1 through Fig. 7 in this Bulletin. Do not
install Model F3QR80 Dry sprinklers with the standard (long)
inlet fitting into CPVC fittings that have an internal obstruction
(see Fig. 9); this will damage the sprinkler, the fitting, or both.
Model F3QR80 Dry sprinklers are available with a short “PL”
inlet fitting for installation on CPVC fittings of wet-pipe sprin-
kler systems only.
Model F3QR80 Dry sprinklers connected to wet-pipe sys-
tems must be installed with the Exposed Minimum Barrel
Length required by Fig. 8 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.
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 F3R wrenches are designed to be inserted into
the groves in the sprinkler’s wrench boss as shown
in Fig. 10. The Model XLO2 wrench is designed to fit
into the cup and engage the wrench boss as shown
in Fig. 11. Do NOT wrench any part of the sprinkler
assembly other than the wrench boss. When insert-
ing 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).
3a. Alternatively, where access to the outer tube of
the sprinkler is available, the Model F3QR80 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. 12). 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).
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.
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 di-
rection 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.
