Appliance connections
like an attic or garage, the gas piping can be connected directly to the appliance shut-o
valve without installing a special termination ange or exible appliance connector. (Figure
4.15)
Pad-Mounted Equipment
Gas equipment like pool heaters, generators, heat pumps, and gas air conditioners that are
mounted on concrete pads should connect to the HOME-FLEX® system at a termination
tting with either black steel pipe or an approved outdoor appliance connector. Direct con-
nection of HOME-FLEX® to pad-mounted equipment is allowed when the CSST is securely
supported and protected from physical damage, so long as such practice is permissible by
local and state codes. Any exposed tubing should be wrapped with self-bonding silicone
tape, sealing the tting connection.
Roof Top Equipment
Special mechanical protec-
tion of HOME-FLEX® tubing
is not required for roof-
mounted equipment unless
the tubing may be subject
to physical or environmen-
tal damage in the location.
It is recommended that the
tubing be covered to pro-
tect it from the elements.
HOME-FLEX® tubing should penetrate the roof within 6 feet of the equipment location,
whenever possible. Long runs of tubing on the roof should be supported with nonmetallic
blocks at the intervals specic in Table 4.2, and raised above the roof at the height dictated by
local code. (Figure 4.17)
In addition to nonmetallic blocks, HOME-FLEX®
can be supported with a strut or channel running
from block to block. This provides a secure, dam-
age resistant track for the CSST and allows for the
block spacing to be set at every 8 feet. The chan-
nel run should be a ⁄" galvanized shallow
channel with splice plates at joints and bends.
HOME-FLEX® tubing should be rmly attached to
each block with metallic clamps designed for the
strut, or other appropriate fastener. Black UV resis-
tant cable ties can be used at intermediate points
to ease the rolling out of HOME-FLEX®. Blocks should be
attached to the roof surface in compliance with the roong
manufacturer’s instructions. (Figure 4.18)
Any HOME-FLEX® tubing run vertically up the side of a build-
ing or on a rooftop must be protected in accordance 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 appli-
ance connector should be used to make the connection
from the appliance to the piping system at a special termi-
nation ange, a steel nipple, or a quick-connect device as
described in Section 2.6 (p. 6). Always follow manufac-
turer’s installation instructions. (Figure 4.19)
