General
Description
The GRINNELL G-FIRE Figure 522
Sprinkler Outlet is an economical alter-
native to welded pipe outlets on steel
pipe. The Figure 522 Sprinkler Outlet
may be used with full lengths of pipe
and eliminates threading and welding,
decreasing waste and installation time.
The Figure 522 Sprinkler Outlet may be
used in wet pipe, dry pipe, and deluge
systems.
The 1/2 in. and 3/4 in. nominal outlet
sizes are intended for use in fire pro-
tection systems leading to a direct con-
nection to a sprinkler only. The 1 inch
nominal outlet size is intended for use
in fire protection systems leading to a
direct connection to a sprinkler or a
connection to system piping. These fit-
tings should be used for hydraulically
calculated systems only.
NOTICE
Never remove any piping component
nor correct or modify any piping defi-
ciencies without first de-pressurizing
and draining the system. Failure to do
so may result in serious personal injury,
property damage, and/or impaired
device performance.
It is the designer’s responsibility
to select products suitable for the
intended service and to ensure that
pressure ratings and performance
data are not exceeded. Material and
gasket selection should be verified to
be compatible for the specific applica-
tion. Always read and understand the
installation instructions.
The GRINNELL G-FIRE Figure 522
Sprinkler Outlet described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the Approval agency, in addition to
the standards of any other authorities
having jurisdiction. Failure to do so
may result in serious personal injury
or impair the performance of these
devices.
The owner is responsible for main-
taining their mechanical system and
devices in proper operating condition.
The installing contractor or device man-
ufacturer should be contacted with any
questions.

Installation
The GRINNELL G-FIRE Figure 522
Sprinkler Outlets are to be installed in
accordance with this section.
Step 1. Select hole size from Table A.
The hole must be drilled on the pipe
center-line. Remove any sharp or
rough edges from the hole or upper
housing contact area. The gasket-
seating surface on the pipe should
be examined to verify all loose debris,
dirt, chips, paint and any other foreign
material such as grease are removed.
Verify that the gasket grade is correct
for the application intended. Refer to
Technical Data Sheet TFP1895 for
additional gasket information.
Step 2. Check for proper gasket posi-
tioning in the housing. The alignment
tabs on the gasket should fit into the
recesses of the housing. Check sealing
surface for cuts or imperfections that
would affect sealing. For Wet Based
applications, no lubricant is required.
When used for Dry Pipe and Freezer
applications, use a petroleum-free
silicon based lubricant.
Step 3. With one nut and bolt removed
and the other nut threaded out flush
with the end of the screw, swing the
housing over the hole in the pipe.
Step 4. Verify that the housing outlet
locating collar is positioned in the hole.
Insert the other bolt into the housing
and rotate the nuts clockwise until
finger tight. Verify that the bolt heads
are fully seated in the housing.
Step 5. Alternate when tightening
nuts until properly torqued to between
15 - 20 lb-ft (20 - 27 N·m) with even
gaps between the bolt pads. Uneven
tightening can cause the gasket to
pinch or bind. Over torquing can
damage the product or thin wall pipe
and will not increase sealing efficiency.

NOTES:
a. Proper hole preparation is required for effective sealing and performance. Check the pipe seal surface
within 5/8 in. (15.88 mm) of the hole to be certain it is free from conditions that would affect proper gasket
sealing. Remove any sharp or rough edges from the hole or upper housing contact area that might affect
assembly, proper seating of the locating collar, or ow from the outlet. Check gasket grade to be certain it is
suitable for the service. The use of threaded products other than steel pipe, such as dry pendants, etc. may not
be compatible with the female threaded outlet on the Mechanical Tee. Always conrm compatibility by
contacting GRINNELL Products.
