Section 4: Installation Practices
S . I P
4.1 General Provisions
a) Precautions must be taken to ensure any exposed FlashShield™ CSST is not damaged or abused during building
construction. All tubing, fittings and hardware should be stored in a clean, dry location prior to installation.
b) Open ends of the tubing are to be temporarily plugged or taped closed prior to installation to prevent entrance of dirt,
dust or other debris.
c) e protective plastic jacketing should be kept in place as much as possible to protect the tubing from corrosive threats.
Contact with chemicals containing chlorides must be followed by a thorough rinse and wipe dry. is includes fluxes used
to solder copper tubing, acid based cleaners used to wash masonry, and some bubble test solutions.
d) Protect tubing from contact with sharp objects. When installing in, through, or around sharp metal structuring (i.e. metal
studs, sheet metal, I-beams, and fireplace enclosures) non-metallic gromets or tubing should be used to prevent any direct
contact which could subject tubing to damage.
e) Avoid stressing the tubing or fittings with tight bends, kinks, twists, stretching or repetitive bending. Refer to Table 4-1
below for the recommended minimum bend radius for FlashShield™ CSST (Fig. 4-1).

1-1/4" 37 3.0" 5.0"
1-1/2" 48 3.0" 5.0"
2" 60 4.0" 6.0"
f) Supporting FlashShield™ CSST - Tubing shall be supported in a workmanlike manner with pipe straps, bands or hangers
suitable for the size and weight of the tubing, at intervals not to exceed those shown in Table 4-3. A proper support is one
which is designed as a pipe hanger, does not damage the tubing during installation, and provides full support. “J” Hooks may
not be used as they may damage the FlashShield™ CSST. Zip ties/cable ties are not to be used as a primary support but may
be used to organize or bundle FlashShield™ CSST. See Table 4-5 for supporting FlashShield™ CSST in a rooftop application.
g) FlashShield™ CSST must be rigidly terminated with a FlashShield™ or XR3 series fitting. is can be achieved by
terminating with a rigidly mounted fitting or by terminating with a fitting threaded onto a rigid gas-piping component.
