PART 3: EXECUTION

3.01 preparation

A. The contractor will confirm the correct size supports has been chosen.

3.02 INSTALLATION

  1. Install the supports in accordance to manufacturer’s recommendations
  1. Clear roof-surface of loose gravel and ballast in large enough area enabling base to sit flat on roof-surface.
  1. Contact roof system manufacturer as to requirements of separator sheet between each support and the installed roof system.
  1. Placement recommendations;
  1. The following are to be used as minimum recommendations. For specific requirements, the installer should contact the project engineer.
  2. For pipe diameters of 2” to 5” – space supports at a maximum distance of 10’ apart.
  3. For pipe diameters of 1 ½” – space supports at a maximum distance of 8’ apart.
  4. For pipe diameters less than 1 ½” – space supports at a maximum distance of 6’ apart.
  5. Along with the above noted spacing recommendations, one additional support should be placed at every union and source and along with one at side of junctions.
  1. If required to adhere to the roof surface use proper adhesion.
  2. For modified, built-up and TPO roof systems, use an NP 1 type sealant.
  3. For EPDM roof systems, use seam tape.
  4. For PVC roof systems, weld a PVC slip sheet to the surface and adhere the PipeGuard with an NP 1 type sealant to the slip sheet.

PART 4: MAINTENANCE

4.01 RECOMMENDATION

A.  On a semi-annual basis, a visual inspection of the installed PipeGuards should be made.

B.  Inspect for the following;

1.  PipeGuard has not disengaged from pipe.

2.  PipeGuard sitting flat on the roof surface.

3.  Proper placement spacing as outlined in 3.02 - D.

C. Adjust PipeGuards to comply with above noted sections.
