Specifications
The pipe shall be made from NSF listed Type 1, flame retardant polypropylene conforming to ASTM D4101, with a maximum average flame spread of zero seconds and a maximum extent of burning of 13 mm, in accordance with ASTM D635. Matched fittings shall be made from NSF-listed flame retardant polypropylene with an average maximum burn time of 80 seconds and maximum extent of burning of 20 mm in accordance with ASTM D635.
If NFRPP pipe is specified, it shall be made from NSF 14 listed and CSA certified Schedule 40 PP as manufactured by IPEX. The pipe shall comply with ASTM F1412 and the material used shall comply with the material requirements of ASTM D4101.
Fittings shall be NSF listed and have an integral heavy gauge, nickel/chrome electrical resistance wire molded in place in the fitting body. Copper wire elements, loose wire, or other loose joint components, are prohibited. Fittings shall be Enfield or approved equal.
Connections between polypropylene pipe and fittings shall be made using the Enfield™ joint. All joints shall have a fusion cycle controlled by a microprocessor-operated, waterproof, Enfusion control unit equipped with input and output voltage sensors, ambient temperature sensors to automatically adjust fusion time, and audible alarms to indicate cycle interruptions and completion of the joining process.
The unit shall be capable of fusing multiple joints and with a minimum capability of eight 2″ joints with the same fusion time as a single joint. Connections between polypropylene and other piping materials shall be made using Enfield adapters according to the manufacturer’s (IPEX) recommendations. All electrofusion machines shall be third-party certified by UL and CSA.
Installation and testing shall be in accordance with the contract drawings, the manufacturer’s recommendations, and the local plumbing codes. Testing with compressed air is prohibited.
The entire system shall be installed free of stress and in proper alignment. Horizontal supports shall provide a wide bearing area and be free of burrs or sharp edges. Support spacings shall be in accordance with the manufacturer’s recommendations and local plumbing codes.
Vertical piping has riser clamps on each floor. Pipe supports should be installed so that horizontal piping is in uniform alignment and with a uniform slope of at least 1/8″.
