Installation Practices
Outdoor Appliances: Barbecue Grills, Gaslights,
and Heaters
As with movable indoor appliances, movable bar-
becue grills, heaters, and other appliances should
not be directly attached to HOME-FLEX® CSST. An
approved outdoor appliance connector should
be used to make the connection from the appli-
ance 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 installation instructions. (Figure
4.20)
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 non-metal-
lic conduit. Underground tubing runs must follow the
guidelines in Section 4.9 (p. 31). The exposed end of con-
duit must be sealed to prevent foreign objects (dirt, water,
pests, etc.) from entering. (Figure 4.21 and Figure 4.22)
Fireplace Installations
Most gas replaces and gas logs are consid-
ered xed appliances which can be directly
connected with HOME-FLEX® without a spe-
cial termination ange (ANSI Z24.50). Direct
delivery of gas is approved for decorative
and heat generating replaces and for gas
logs used in masonry and pre-fabricated re-
places. (Figure 4.23)
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 key valve or another location outside the replace. The nal attach-
ment 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
