Troubleshooting Fitting Assembly and Correcting Leaks
Step 1: Gradually tighten tting until leak stops.
Step 2: If leak does not stop after reaching maximum torque, stop,
open the assembly and check for:
a. Proper tting assembly. Make sure the gasket is installed in the
base of the parallel thread of the tting. If it was not, install the gas-
ket, repeat assembly steps, and test for leaks again. Gaskets cannot be reused:
if it was installed, replace it with a new gasket and continue to step 2b.
b. Obstructing material in assembly. If dirt, shavings, jacket remnants, etc. are
found, remove material and reassemble, checking for leaks again.
c. Integrity of assembly pieces. If the retainer ring or the gasket are cracked,
misshapen or otherwise damaged, replace them and repeat assembly.
Note: DO NOT use sealant tape or pipe dope on parallel threads.
WARNING!
Improper installation or operation of the
system may result in re, explosion, or
asphyxiation. Only the components provided

may result in poor system performance and
serious bodily injury or property damage.

1: Cut pipe to length. Route CSST through structure to the desired loca-
tion of the termination ange. Bend tubing as required so it exits the structure
in desired direction of the termination plate. Cut the excess CSST so about 2” of
tubing extends beyond the wall.
2: Remove pipe jacket. Using a utility knife, strip the yellow tubing jack-
et back 2 valleys from the end of the tubing. Also remove the yellow warning
label from the tting assembly. DO NOT USE A TUBE CUTTER.
3: Place ange. Slide the termination ange over the tubing with the
threaded end pointing toward the end of the tubing. DO NOT SECURE THE
FLANGE.
4: Place retainer ring. Place the retainer ring in the rst valley of the tubing.
Being careful to not dent the tubing, clamp the retainer ring in place by applying
gentle pressure 360° around the ring. It should t tightly and not easily spin around
the tubing.
5: Flange assembly. Pull termination ange toward end of tubing so it
catches on the retainer ring, ensuring that the retainer ring and ange are ush.
The base of the ange should be parallel with tubing corrugation. DO NOT use
sealant tape or pipe dope on parallel threads between ange and tting.
Hold the tting on the NPT thread and attach to termination ange by turning
the ange counter-clockwise onto the tting. Hand tighten.
6: Tighten assembly. Complete tightening with two wrenches to 62 lb.
ft. torque, holding the tting xed with one wrench while turning the ange
counter-clockwise with the other. Push the assembly back ush to the wall and
secure with screws.
