Trim the rubber boot (using scissors or a utility knife), cutting along the marked measurement lines. See Figure 10.18. Use the 150 mm line for SLP, 210 mm for DVP.

Lubricate pipe or flue with water and slide the flashing down. It may be necessary to trim the top shingles around the base of the rubber boot to ensure a good fit.
