Installation Instructions
When used on wet pipe systems, Reliable Model F3QR56
dry sprinklers may be installed in ductile or malleable cast iron
threaded tees, or CPVC tees and adapters upon verification
that the sprinkler inlet fitting does not interfere with the interior
of the fitting (see Figure 12).
When used on dry pipe systems, Reliable Model F3QR56
dry pendent sprinklers MUST ONLY BE installed in the outlets
of ductile or malleable cast iron threaded tees on horizontal pipe
such that the inlet of the sprinkler protrudes above the bottom
level of the pipe.
When used on dry pipe systems, Reliable Model F3QR56
dry sidewall and dry upright sprinklers may be installed in duc-
tile or malleable cast iron threaded tees, or CPVC tees and
adapters upon verification that the sprinkler inlet fitting does not
interfere with the interior of the fitting (see Figure 12).
DO NOT install Reliable dry sprinklers into elbows or cou-
plings, welded outlets, mechanical tees, or gasket sealed CPVC
fittings.
Dry sprinklers connected to wet pipe systems must be in-
stalled as indicated in Figure 11 and as required by NFPA 13
with the Exposed Minimum Barrel Length 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 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 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 Mod
-
el F3R wrench is designed to be inserted into the groves
in the sprinkler’s wrench boss as shown in Fig. 13. The
Model XLO2 wrench is designed to fit into the cup and
engage the wrench boss as shown in Fig. 14. 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 dam-
age 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 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 sprin-
kler 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. 15). Do NOT wrench any other por-
tion of the sprinkler assembly. A pipe wrench can in-
stall 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 instal-
lation 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 installed
by slipping the escutcheon over the can until the es-
cutcheon 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 cov-
er 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.
