HOME-FLEX CSST 31
Meter connections
4.5 Meter connections
Natural gas meters are generally structurally supported independent of the building struc-
ture and piping system. When the gas meter is independently supported, HOME-FLEX® can,
in some localities, be used to connect the meter to the building gas system. If the gas meter
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.

Direct Connection
If a direct connection from HOME-FLEX® to an independently supported gas meter is per-
mitted 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)
