Section 4: Installation Practices
4.6.4 Special Applications
a) Roof Mounted Equipment (Fig. 4-68) – FlashShield™ Flexible Gas Piping can be used in an outdoor rooftop application.
When used in this application FlashShield™ is to be supported off the surface of the roofing material. is support allows
for adequate drainage on the roof, product protection from snow, and is commonly required by code.
When FlashShield™ Flexible Gas Piping is installed in an outdoor rooftop application the following requirements must
be met:
1. Support materials will be selected to provide an adequate anchoring point that addresses the lightweight flexible nature
of FlashShield™. is can be accomplished through either the weight of the support or adhering the support to the roof
materials. e support materials must also be selected to be non-damaging to the roofing material. (Check with roof
material manufacturer for approved adhering methods and non-damaging materials/installations.)
2. It is also important to select the appropriate metal pipe clamps or straps to firmly affix the tubing to the support.
3. e supports shall lift the tubing at least 3" from the surface of the roof, higher as required by code or local conditions.
(Check with local code officials to determine height requirements as defined by the local code or conditions).
4. Support spacing will follow the recommendations as outlined in Table 4-5 below.

FlashShield™ shall penetrate roofing in the manner and using the materials as defined by the roofing manufacturer in order
to maintain the manufacturer’s warranty (Figures 4-69 and 4-70). When passing through the deck FlashShield™ must be
properly terminated or pass through an appropriate fixed conduit (Figures 4-71 and 4-72). NOTE: As roofing manufacturers
generally have proprietary penetration systems and require trained installers, it is extremely important to obtain approval and
instructions from the roofing manufacturer prior to performing any work. Failure to do so can result in voiding the roofing
warranty.
Lengths of FlashShield™ CSST
which run vertically up the side
of the building shall be protected
in accordance with the General
Provisions section of these
guidelines, Section 4.3.6.
