Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is required that putty tape be used between the flashing and the roof. The flashing must be secured to the roof using #8 x 3/4" screws and then sealed with roof coating to prevent leakage through the screw holes. A roof coating must also be applied around the perimeter of the flashing to provide a proper seal.
Storm Collar Installation
Place storm collar over pipe and slide down until it is snug against the open edge of the flashing (see Figure 14). Apply waterproof caulk around the perimeter of the collar to provide a proper seal.

Chase installations
Instructions for chase installations are included with the chase style termination chosen. In a multiple chase installation, be sure to provide adequate distance between terminations to prevent smoke spillage from one termination to another. Terminations be separated a minimum of 24" center to center and stacked at a minimum vertical height difference of 18" (see Figure 16).
Note: If a decorative shroud is to be installed, contact the manufacturer for specifications.
