    1. Choose the appropriate size. If necessary trip the opening to to about 20% smaller than the pipe diameter.
    2. Wrap the retrofit around the pipe and install all snap rivets to seal the flange.
    3. Press the flashing down, bending it to conform to the roof profile or roof irregularities. A blunt tool will help press the flashing into tight roof angles.
    4. Apply a silicone sealant between the flashing base & the roof.
    5. Use fasteners to complete sealing. For UPC installation, fastener spacing may not exceed 1½".
    6. Install the supplied cable tie at the upper-most part of the flashing & apply sealant to any gaps.
