VERSIWELDO Certified <br /> TPO PIPE SEALS Fabricated <br /> Accessory <br /> Installation <br /> 1. Cut pipe seal between the two raised "ribs"to the <br /> desired diameter as illustrated on the flange of the <br /> pipe seal. (Do not cut off both raised "ribs"). <br /> 2. Pull pipe seal over pipe until base flange is in contact <br /> with the membrane. (Application of heat to the top <br /> portion of the pipe seal may be necessary to allow <br /> installation over the pipe). <br /> IF <br /> 3. Mark pipe around the top of the TPO Pipe Seal. <br /> 4. Pull TPO Pipe Seal upwards on pipe until mark on the <br /> pipe is visible. <br /> — 5. Install Water Cut-off Mastic below mark which <br /> indicates the top of the installed TPO Pipe Seal. <br /> 6. Pull TPO Pipe Seal back down over pipe and into <br /> Overview position. <br /> 7. Heat weld the TPO Pipe Seal base flange to deck <br /> Let Versico simplify your next VersiWeld TPO installation membrane(the hand-welder temperature setting <br /> with TPO Molded Pipe Seals.TPO Pipe Seals are injection should be between 5 and 6). <br /> molded, pre-formed flashings for pipes 3/4"(19.0 mm)to 8" 8. Install a stainless steel universal clamping ring to <br /> (203.2 mm)in diameter.TPO Pipe Seals are packaged in provide constant compression of the sealant. <br /> boxes of eight and come with universal stainless steel <br /> clamping rings. REVIEW CURRENT VERSICO SPECIFICATIONS AND DETAILS <br /> FOR SPECIFIC INSTALLATION REQUIREMENTS. <br /> VersiWeld TPO Molded Pipe Seals are part of the <br /> Certified Fabricated Accessory(CFA)program. Certified Precautions <br /> Fabricated Accessories are the only factory-fabricated <br /> TPO accessories that meet the stringent quality tolerances 1. Remove all lead and other flashing. <br /> required to be included in a Versico warranted <br /> roofing system. 2. Temperature of pipe must not exceed 160°F(71°C). <br /> 3. When used with mechanically attached membrane, <br /> Features and Benefits install a minimum of four fastening plates around <br /> pipe penetrations. Position fastening plates around <br /> • Provides a reliable method of waterproofing round the penetration so the plates are covered by the <br /> pipe penetrations pipe seal flange.A minimum 11/2-inch wide weld <br /> must be maintained around the outer edge of the <br /> • Provides a substantial labor savings compared to flange beyond the plates. If fastening plates cannot <br /> field fabricating from non-reinforced flashing be installed in a manner to allow a minimum 11/2-inch <br /> • Provides more consistent appearance than field- weld,the plates must be placed outside the TPO Pipe <br /> fabricated pipe flashings Seal flange and covered with a reinforced VersiWeld <br /> • Double-ribbed cutting guide provides easier, overlay. <br /> smoother and straighter cuts 4. Store pre-molded pipe seals in a cool, shaded area <br /> • Rib design also keeps the clamp in the proper and cover with light-colored, breathable,waterproof <br /> position for the life of the roofing system tarpaulins.TPO Pipe Seals or membrane that has been <br /> exposed to the weather prior to use must be prepared <br /> with Weathered Membrane Cleaner prior to hot-air <br /> welding. <br /> V ERSICO _ A SINGLE SOURCE FOR SINGLE-PLY ROOFING <br /> `_' <br /> ROOFING SYSTEMS Versico, PO Box 1289, Carlisle, PA 17013 <br /> Tel: 800.992.7663 Fax: 717.960.4036 Web: www.versico.com <br />
