Installation Instructions
When used on wet pipe systems, Reliable Model G5-56
dry pendent sprinklers may be installed in ductile or malleable
cast iron threaded tees, or CPVC tees and adapters upon veri-
fication that the sprinkler inlet fitting does not interfere with the
interior of the fitting (see Figure 3).
When used on dry pipe systems, Reliable Model G5-56 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.
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 2 and as required by NFPA 13 with
the Exposed Minimum Barrel Length located in a heated area.
DO NOT install the Reliable Model G5-56 dry pendent sprin-
kler in ceilings that have positive pressure in the space above.
The following steps must be followed for
installation:
1. Cut a 2
5
/
8
-inch (67mm) diameter hole in the ceiling directly
in-line with the outlet of the tee.
2. Apply pipe joint compound or Polytetrafluoroethylene
(PTFE) tape to the threads of the sprinkler’s inlet fitting.
3. A protective cap is provided to protect the drop-down
sprinkler deflector from damage which could occur during
construction before the cover plate is installed. The cap is
factory installed inside the sprinkler cup. Remove the cap
to install sprinkler, Step 4, then reinstall cap until the cover
plate is installed.
4. Install the sprinkler in the tee using the Model FC wrench.
The Model FC wrench has a socket drive which is inserted
into the sprinkler’s cup and around the body of the sprinkler
prior to installation of the sprinkler. Do NOT wrench any of
the part of the sprinkler/cup assembly. The sprinkler is then
tightened into the pipe fitting to achieve a leak free connec -
tion. The recommended minimum to maximum installation
torque is 22-30 lb-ft (30 – 40 N-m). When inserting or re-
moving the wrench from the sprinkler/cup assembly, care
should be taken to prevent damage to the sprinkler. Rein-
stall the protective cap following installation of the sprinkler,
until the cover plate is installed.
a. Alternatively, where access to the outer tube of the
sprinkler is available, the Model G5-56 Dry sprinkler
may be installed using a pipe wrench. The protec-
tive cap should not be removed to install the sprin-
kler with a pipe wrench. The pipe wrench shall only
be permitted to interface with the steel outer tube
portion of the sprinkler (Item #8 in Fig. 4). Do NOT
wrench any other portion of the sprinkler/cup as-
sembly. A pipe wrench can install the sprinkler into
the fitting with a large amount of torque; consider -
ation should be given to the need for future removal
of the sprinklers 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).
5. To install the cover plate, remove the protective cap and in-
stall the cover plate by hand turning the cover in the clock-
wise direction until it is tight against the ceiling. For Model
G4 /G5 QR Gasket and Model G4 /G5 SR Gasket cover
plates, the gasket should be attached to the flange of the
cover plate skirt only. Do not glue the gasket in place or
allow the gasket to overlap both the cover plate and the
flange of the skirt.
