Disassemble Vent Sections; Install Metal Roof Flashing - Heat & Glo Everest Owner's Manual

D. Disassemble Vent Sections
• Rotate either section (see Figure 10.9) so the seams
on both pipe sections are aligned as shown in Figure
10.10.
• Pull carefully to separate the pieces of pipe.

Figure 10.10 Align and Disassemble Vent Sections
E. Install Metal Roof Flashing
• See minimum vent heights for various pitched roofs
(Figure 10.11) to determine the length of pipe to extend
through the roof.
• Slide the roof fl ashing over the pipe sections extending
through the roof as shown in Figure 10.12.

NOTICE: Failure to properly caulk the roof fl ashing and
pipe seams may permit entry of water.
• Caulk the gap between the roof fl ashing and the outside
diameter of the pipe.
• Caulk the perimeter of the fl ashing where it contacts the
roof surface. See Figure 10.12.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
