Installation Instructions

PROTECTION DEVICES
PROTECTION IS REQUIRED WHEN THE CSST
TUBING IS CONCEALED, CONSTRAINED AND
WITHIN 3 INCHES OF A POTENTIAL THREAT.
PRO-FLEX
®
must be protected where puncture threat exist.
Install protection devices, i.e. striker plates as shown, to pro-
tect the installed tubing from penetrations by drill bits, nails,
screws and in those areas where the tubing is concealed
and will not be free to move to avoid such puncture threats.
Shielding is defined as 3" (76.2mm) x 7" (177.8mm) protect-
ed area shall be around support points. (when tubing is
within 3" (76.2mm) of an interior surface, shielding is
required a minimum of 5" (127mm) beyond the support. A 2
x 4 will always require protection because any and all clear-
ance holes for tubing will be less than 3" (76.2mm) away
from the 2 x 4 area. Protection/Shielding is required 5"
(127mm) beyond the support area when points of penetra-
tion are less than 3" (76.2mm) from any surface such as
studs, edge of a joist. Refer to figures 4-10, 4-11.
Long Unsupported Vertical Tubing Rugs (over 3 ft.) within a Hollow
Interior Wall Partition. Shielding Required at Support Area When
Points of penetration are Less than 2" From any Wall Surface.
When the exterior wall is finished before the installation of
the gas tubing and a striker plate cannot be installed, a
protective schedule 40 steel pipe sleeve shall be placed
around the tubing. The sleeve shall be secured to the sill or
stud, be at least 1/2in. (12.7mm) larger in its internal diame-
ter than the O.D. of the CSST, and extend no more than 4 in.
(100 mm) above the sill or beyond the stud. A striker plate
shall also be placed on the accessible side of the sill or stud
as required.
Install Floppy-Flex
™
, strip wound steel conduit, which is
another protection device, which can and should be used at
points of support such as gas outlet terminations, short
tubing runs and where tubing is routed horizontally between
studs. Strip wound (Floppy-Flex
™
) is required along the
length within a wall partition when tubing cannot be
displaced a minimum of 3" (76.2mm) or if distances between
supports are less than 2 ft.
NOTE: The ID of the conduit (Floppy-Flex
™
) must be at least 1/2" larger than
the OD of the CSST Tubing.
Long Unsupported V
ertical Tubing Run (over 3 ft.) from a Termination Outlet
Within a Wall Partition. Shielding Required At Termination Outlet and Along
Tubing Length That Is Non-supported and Cannot Be Displaced a Minimum of
3 in. in the Direction Away From Potential Penetration.

Where Finished Exterior Wall Does Not Permit Installation of
Striker Plate, Protective Sleeve is Required.
