Installation Instructions

1. Clean and dry the roof surface thoroughly.

2. Cut the cone to match the pipe’s outer diameter for a snug fit.

3. Position the flashing so the base conforms to the roof’s corrugation profile.

4. Secure the base with corrosion-resistant screws (Class 3 or 4) spaced evenly around the perimeter.

5. Apply a compatible neutral-cure sealant to the outer edge if required.

6. For retrofit applications, split the cone carefully, fit around the pipe, and reseal securely.
