Installation Practices
Any HOME-FLEX® tubing run vertically up the side of a building must be protected in accor-
dance with "Outdoor Installation Issues" in Section 4.3.
Outdoor Appliances: Barbecue Grills, Gaslights, and Heaters
As with movable indoor appliances, movable barbecue grills,
heaters, and other appliances should not be directly attached
to HOME-FLEX® CSST. An approved outdoor appliance con-
nector should be used to make the connection from the
appliance to the piping system at a special termination
ange, a steel nipple, or a quick-connect device as described
in Section 2.6 (p. 6). Always follow manufacturer’s instal-
lation instructions. (Figure 4.19)
Non-movable outdoor appliances, such as
xed barbecues, gas lights, or heaters can be
directly connected with HOME-FLEX® so long
as such connections are permissible by local
code. On a deck, the outdoor portion of the
tubing run must be supported against the
sides of joists. If the deck elevation is below
the building foundation, exposed tubing
must be routed through a protective water-
tight nonmetallic conduit. Underground tubing runs must follow the guidelines in Section
4.9 (p. 33). The exposed end of conduit must be sealed to prevent foreign objects (dirt,
water, pests, etc.) from entering. (Figure 4.20 and Figure 4.21)
Fireplace Installations
Most gas replaces and gas logs are con-
sidered xed appliances which can be
directly connected with HOME-FLEX®
without a special termination ange (ANSI
Z24.50). Direct delivery of gas is approved
for decorative and heat generating re-
places and for gas logs used in masonry
and pre-fabricated replaces. (Figure 4.22)
DO NOT use HOME-FLEX® CSST to connect
gas log lighter or gas wands for use in all-
fuel (wood burning) replaces. For gas log
lighter installations in all-fuel replaces,
HOME-FLEX® must be terminated at the
