Installation Guide

HOME-FLEX CSST 33
Appliance connections
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 permissi-
ble by local code. On a deck, the outdoor
portion of the tubing run must be support-
ed against the sides of joists. If the deck
elevation is below the building founda-
tion, exposed tubing must be routed through a protective water-tight nonmetallic conduit.
Underground tubing runs must follow the guidelines in Section 4.9 (p. 36). The exposed
end of conduit must be sealed to prevent foreign objects (dirt, water, pests, etc.) from enter-
ing. (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
to the key valve for decorative and heat
generating replaces and for gas logs
used in masonry and pre-fabricated re-
places. (Figure 4.22)
DO NOT use HOME-FLEX® CSST to con-
nect gas log lighter or gas wands for use
in all-fuel (wood burning) replaces. For
gas log lighter installations in all-fuel re-
places, HOME-FLEX® must be terminated
at the key valve or another location outside the replace. The nal attachment to the lighter
should be made using black steel pipe.
Should HOME-FLEX® need to be installed through masonry materials in the replace con-
struction, the yellow jacket should remain intact and the HOME-FLEX® tubing should be
routed through a nonmetallic sleeve appropriate for the application. Sleeves are not required
for routing through ceramic liner in heat generating replaces. Spaces between the jack-
et and penetration at interior and/or exterior locations can be caulked. The jacket can be
removed inside the rebox.
Attachment to the HOME-FLEX® system is usually made at the replace shut-o valve, often
located in the control area beneath the burner unit or at the side of the log set. HOME-FLEX®
can be run into the lower control area without removal of the polyethylene jacket. If the re-
