Section 4: Installation Practices
4.4.2 Steel Conduit
At termination points not covered by the ANSI standard,
floppy steel conduit (heavy wall) shall be installed as additional
protection (Fig. 4-54 and 4-55). FlashShield™ requires a
minimum of six inches of conduit and supplies precut conduit
in one foot lengths. Floppy Steel conduit should not be used
in place of hardened steel striker plates when passing through
structural members.
4.5 Meter
e gas piping for the meter stub-out is usually subject to local requirements such as size, location, and material type. It is
always important to confirm local code and utility requirements. FlashShield recommends the use of 1/2" CSST or greater
as the minimum trunk line size. Size 3/8" should not be used for trunk lines. is will allow for the addition of future gas
appliances and minimize the opportunity for whistling.
a) Unsupported Meters – Meters that depend on
the service supply line and/or the house piping
for support shall not be directly connected to the
FlashShield™ CSST. As shown in the Figures 4-56
and 4-57, a rigid connection point is created using
a FlashShield™ termination fitting, Gastite® designed
stub-out or rigid pipe components.
b) Self-Supported Meters – Meters that are independently
supported with a bracket can be directly connected
to the FlashShield™ CSST as shown in Figure 4-58.
If practical, direct FlashShield™ CSST connections
shall include a 3 to 6 inch loop of tubing (as shown)
to accommodate differential settling and meter
movement. No mechanical protection of the tubing
is required for outdoor meter connections; however,
ensure that the local utility supports this practice
as some utilities have regulations specifying meter
attachments. Ensure that any exposed sections (jacket
removed) of the stainless tubing at the fitting are
wrapped with tape. is is especially important with
masonry constructions.
c) Electrical bonding connections made at the gas meter must comply with Section 4.10 of this guide.
