Pipe shall be supported sufficiently to prevent sagging. InstallationPipe and fittings shall be installed according to current installation instructions as delivered in print or documented online at . An on-site installation seminar shall be conducted by GF personnel who are certified to conduct said seminar. Seminar topics shall include all aspects of product installation (storage, set up, support spacing, fusion process, mechanical joint process, testing procedure, etc.). At the conclusion of the installation seminar, all installers will be given a certification test and, upon successful completion of said test, will be issued a certification card verifying they have met the requirements of the manufacturer with regards to knowledge of proper product installation and testing methods.Only the following GF Piping Systems fusion units and joining methods may be used to install the Fuseal? PP and Fuseal 25/50? PVDF Waste Piping system:For Electrofusion Installation: MSA-250SE or Electro Plus? Fusion MachineFor mechanical joint (Fuseal Fast-Lock): Contractor shall use either an electric / cordless drill or a standard ratchet with an 8mm or 10mm socket driver for Fast-Lock? fitting installation. Piping ends shall not be grooved when installing this system. Installer shall ensure that all pipe and fittings used for the special waste piping system are components of the same system. No mixing of various manufacturers’ pipe and or fittings shall be allowed. Acceptable manufacturers are GF Piping Systems LLC or approved equal.Pipe/Valve Hangers and SupportsNon-Restrictive Horizontal Pipe ClampsPlastic pipes shall be supported at distances recommended by the manufacturer according to load, material, temperature, pipe wall thickness and diameter.Plastic pipe supports shall be constructed of an exterior metal supporting bracket of gauge 7 or gauge 11 thickness, depending on size, and an independent plastic insert sleeve sized to allow not more than ?" annular space between supported pipe and sleeve. Only insert sleeves of the indicated size shall be used for the corresponding supported pipe and sleeve. Only insert sleeves of the indicated size shall be used for the corresponding supported pipe. Supports shall be affixed using appropriate mounting bolts, nuts and washers to 12 gauge rolled structural steel channel, 1 5/8" inch by 1 5/8" minimum, or mounted to structurally sound surfaces suitable to accept mounting hardware.Non-Restrictive Saddle Hangers Pipe SupportsSaddle type hangers shall be constructed from 12 gauge rolled structural steel channel, 1 5/8 inch x 1 5/8 inch minimum, strut or stronger as required suitable to support an exterior metal supporting bracket and an independent plastic insert sleeve sized to allow not more than 1/4 inch annular space between supported pipe and sleeve.Non-Restrictive Clevis Hangers Pipe SupportsClevis type hangers shall be constructed of an exterior metal supporting bracket and an independent plastic insert sleeve sized to allow not more than ? inch annular space between supported pipe and sleeve. Only insert sleeves of the indicated size shall be affixed to an independent clevis hanger bracket with means to be mounted using all thread rod with appropriate nuts and washers and sized per MSS-SP-5.Non-Restrictive Vertical Pipe SupportsVertical supports shall be mounted similarly to horizontal support with the addition of 35 durometer cushion strips mounted to both sides of plastic insert sleeve.Thermal Compensating Valve SupportsValves shall be supported at distances as recommended by manufacturers and/or according to load, material, temperature, pipe wall thickness and diameter.Plastic valve supports shall be a two piece construction, with a primary supporting mounting bracket designed to be structurally attached to a flat surface or a steel strut support of 40mm (1 5/8 inches) width with slots to accept mounting hardware and a second, interlocking valve sliding bracket with suitable slots to affix and mount the valve. When assembled, the valve sliding bracket shall be interlocked with the mounting bracket to allow linear movement along a plane that is in-line with the installed pipe.Location of the sliding valve support along the mounting bracket shall take into consideration the installation and operating system temperatures to gain maximum valve support throughout an anticipated temperature cycle of the piping system. If equal temperature changes are anticipated (above and below installation temperature) or if conditions are unknown, sliding valve support shall be mounted midway along mountain bracket.All valve supports shall be of a two-piece, interlocking construction, manufactured of UV resistant materials and designed to provide full valve support while allowing for linear movement when subjected to thermal expansion or contraction forces acting on the installed piping system. The valve mounting bracket shall provide means of valve attachment without restricting valve movement when affixed to valve mounting support bracket.ManufacturerAll supports and hangers specified above shall be Stress Less? Pipe and Valve Support system as manufactured by GF Piping Systems LLC or approved equal.TestingThe system shall be tested in accordance with all local plumbing codes. All sections of the piping system shall be tested subject to the requirements of the inspectional authority having jurisdiction. Suggested Fuseal, Fuseal 25/50 and Fuseal Fast-Lock testing covers a maximum of 30 foot head of water (approx. 15 PSI ) for fusion system, 10 foot head (5 PSI) for mechanical joint. Systems are not to be tested with air or any other gas, unless done so in a manner acceptable to or presented by GF Piping Systems LLC personnel. Electrofusion joints may be pressure tested 10 minutes after fusion is completed. Fast-Lock? mechanical joint fittings may be pressure tested immediately after assembly.Fuseal PP and PVDF electrofusion joined pipe and fitting systems may be installed for conveyance of pumped discharge up to 50 PSI.Fuseal Fast-Lock? mechanical joint fittings may be installed for installations where piping system is conveying pumped discharges to 35 PSI. Consult your local GF representative for more information. ................
