UL Listed Fuels Below are the listed fuels that have been tested under UL 971 and are warranted for use with the FlexWorks piping system. 100% ASTM Reference Fuel No. 2 100% ASTM Reference Fuel C 85% Reference Fuel C — 15% MTBE 70% Reference Fuel C — 30% Ethanol 85% Reference Fuel C — 15% Methanol WARNING: FlexWorks piping is not warranted for above ground transmission of flammable liquids due to the possible exposure to fire. 1.2.2 Global Certifications FlexWorks single, FlexWorks double and Vent flexible piping currently carry the following approvals: Kiwa IP ERA LSCDA LNEC/DGE EMPA FTZU SEV STK TUV PUFO PTB TUKES 1.3 Piping Applications OPW-FCS's flexible supply piping can be direct buried underground or installed inside a flexible conduit. • Pressure System Supply Piping • Vent Piping • Suction System Supply Piping • Remote Fill Lines • "Marina Supply Piping *Properly designed applications, such as under dock marina applications may be allowed with special approval and war- ranty restrictions. Other above ground applications containing flammables must have prior written approval and authorization from OPW-FCS for warranty coverage. All installation practices shall comply with the installation instructions contained within this and other OPW-FCS product manuals. WARNING: Flex piping is not warranted for above ground transmission of flammable liquids due to the possible exposure to fire. 1.4 Operating Pressures and Temperatures OPW-FCS flexible piping and its associated fitting systems have a minimum five to one (5:1) safety factor from maximum rated operating pressure for the primary pipe. The product fluids transferred should not exceed the maximum operating pressures indicated on each pipe size. For suction systems the pipe is capable of withstanding 29" mercury vacuum. The maximum temperature rating of OPW FCS's flexible piping is 125°F (52°C).

Refer to the OPW-� FCS Product Price List for pipe diameters and packaging specifications. CAUTION: Do not use knives or razor blades to open carton as damage to piping could occur. 2.0 SPECIFYING FLEXIBLE PIPING OPW-FCS's flexible piping systems offers a variety of piping options for underground fuel delivery applications. Prior to specifying the type of piping required, read section 6 of this manual entitled "Pre -installation Planning". 2.1 Flex Supply Piping FlexWorks flexible supply piping is designed for direct burial as well as indirect burial within flexible ducting for future replacement capabilities. OPW-FCS's supply piping is totally bonded multi -layer composite construction. The inner-most barrier layer is smooth, which enhances hydraulic flow efficiency, and is virtually impervious to gasoline, alcohol blends and a wide variety of other fuels and chemicals. The exterior of the pipe also has a barrier layer to protect the outer wall of the pipe from chemical and microbial attack. OPW-FCS's flexible supply piping is available in both single wall and double wall in continuous lengths. 2.1.1 FlexWorks Single A UL® listed single wall flexible supply piping system that is designed for installation within Access piping. This piping features an enhanced construction that meets the new UL971 standard. 2.1.2 FlexWorks Double A UL listed double wall flexible supply piping system that is designed for . installation within Access (piping. The outer y containment jacket " includes inner stand-off ribs to create a small interstitial space which allows for optimum fluid - migration, continuous =f monitoring and easy periodic testing. This piping features an enhanced construction that meets the new UL971 standard.
