Fitting Assembly
Termination Fitting Assembly (Parts 11-464-XXX)
Step 5 Place tting and assemble ange
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,
being sure the tubing and ange do not
move. Hand tighten.
Step 6 Tighten the ange assembly
Complete tightening with two wrenches
to suggested torque values in Table 4.3 (p.
26), holding the tting xed with one
wrench while turning the ange count-
er-clockwise with the other, being sure that
the tubing does not rotate. Push the assem-
bly back ush to the wall and secure with
screws.
Troubleshooting Fitting Connections
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 gasket, 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) Check for any obstructing material (dirt, shavings, jacket, etc.) in assembly. Remove
material and reassemble, checking for leaks again.
c) Integrity of assembly pieces. If the retainer ring or the gasket are cracked, misshap-
en or otherwise damaged, replace them and repeat assembly.
Note: DO NOT use sealing solution on parallel thread (gasket end) of tting assembly.
Gaskets cannot be reused, and must be replaced if tting assembly is disassembled.
HOME-FLEX® Stainless Steel Manifold Installations
HOME-FLEX® Stainless Steel Manifold ports must be supported with pliers or a wrench when
attaching ttings or pipe to avoid warping of the manifold under torque. Be sure to rmly
hold and support ports, both inlet and outlet, with pliers or wrench when threading and
tightening pipe or ttings into ports and when threading the manifold on to pipe.
Manifolds are to be mounted securely to a supportive structure using one-inch metallic pipe
straps (or similar) to complete installation (see strapping in Figure 4.24 on page 34).
