2 General Rules for Underground Polyethylene Pipe in Propane Applications: For Outdoor Applications For Below Grade/Underground Applications For LP Gas Vapor Service Maximum Pressure of 30 psig Does Not Require a Dielectric Union Above Grade Ends of Polyethylene Shall be Terminated with an Approved Riser

3 Flexible & Semi-Rigid Anodeless Risers

4 40+ years of plastic transitions Sizes 1/2 CTS (.090 wall) through 2 IPS (.216 wall) Flexible & Semi-Rigid options Customizable lengths for both rigid and flexible sections Multiple finish options for corrosion resistance

Features & Benefits The simple design can be installed with one flat jaw wrench extending the life of protective coatings commonly flawed/removed by pipe wrenches.

5 Features & Benefits The simple design can be installed with one flat jaw wrench extending the life of protective coatings commonly flawed/removed by pipe wrenches. Bi-Directional Seal/Ferrule assembly can t be installed improperly where some competitors multiple internal components MUST have proper order and orientation to function properly. No torque requirements!! All X-Risers incorporate the bottoming or positive stop design. Simply tighten the compression nut until it is metal-tometal and you are done. With the swage collar design there is no need for a weep hole which exposes the PE to both UV rays and water Chicago Fittings products are CNC machined providing a high quality product with the most precise threads and design flexibility

6 Design Philosophy It s our feeling at Chicago Fittings, that both LP Gas and Natural Gas systems should have as few joints as possible, and joints should be located above ground wherever possible. The X-Riser with an integral service head adapter accomplishes both of these criteria. The use of an X-Riser removes a minimum of two (2) joints per riser when compared to that of a standard pigtail style riser. In addition, those joints, buried below ground are now moved to a single above grade joint and should a leak occur, it would vent to atmosphere rather than migrating below ground in the path of least resistance. The use of this system eliminates the requirement of an underground stab coupling and/or fused joints. In other words, gas is distributed from tank to building with a solid (jointless) underground pipe. Combining this philosophy with the long list of features & benefits of the Sealastic sealing technology makes the X-Riser the most reliable, safest and most cost effective method for tank to building and main to meter systems.

9 Getting Started. Prior to doing ANY work, contact your local locating service to identify any existing utilities or other potential hazards Trench between Tank and Building a minimum of 12 (per NFPA) Lay Polyethylene into trench leaving plenty of excess material at either end for proper terminations

11 BODY SEAL/FERRULE ASSEMBLY SWIVEL NUT

12 USE APPROVED PIPE DOPE

19 MAKE UP GAP BETWEEN SHOULDERS AFTER HAND TIGHTENING

20 FULLY BOTTOMED

21 Finishing up. Pressure/Leak test per NFPA 54 and/or local/municipal requirements Light Backfill Install Tracer Wire (min. AWG 14) or Tape must be installed for locating purposes Shall not be in direct contact with polyethylene pipe Each end shall be brought above ground at the building wall or riser Final Backfill

Pigtail Notables Typically Requires Two (2) Joints to be Buried at the Bottom of Each Riser Typically Requires a Stab Coupling Requires a Chamfering Tool May Require a Bridging Device or Anti-Shear
