is not supported independent of the building structure or gas piping system, HOME-FLEX®
tubing cannot be used to connect directly to the meter.
Connection by Special Termination Fitting
Do not use HOME-FLEX® CSST as a direct connection if the meter must be supported by the
piping system. If the meter is supported by the building structure, common practice is to
route the CSST system to a termination ange mounted to the exterior of the building, and
to connect the meter to the termination ange with rigid pipe. Alternatively, rigid pipe can
be used to penetrate the building, with an attachment to HOME-FLEX® inside the structure.
(Figure 4.14)
Direct Connection
If a direct connection from HOME-FLEX® to an independently supported gas meter is permit-
ted by the local utility, the connection should include an extra 3-6" of length to allow for
building settling and meter movement. Exposed sections of CSST are to be wrapped with
self-bonding silicone tape, especially if the building is of masonry construction. For direct
connections through masonry construction, a PVC sleeve is required, and also recommended
for wood frame construction. (Figure 4.15)
Note: Check with the local servicing utility prior to directly connecting HOME-FLEX® to the
gas meter as utilities regulate connections to meter attachments.

Termination Fittings with Appliance Connectors
The HOME-FLEX® termination ange tting is designed to service moveable appliances and
quick-connect devices at oor and hallow wall piping outlets (Figure 4.16) in combination
with a HOME-FLEX® Flexible Appliance Connector or similar approved device. The termina-
tion outlet minimizes the need
for concealed ttings and makes
the installation of gas connec-
tions for moveable appliances
easy. The ange plate should be
securely fastened in place during
rough-in of the structure. It may
be attached to a brace spanning
between wall studs or directly to
the oor.
As an alternative to the special
termination ange, a termination
