Vertical Termination Requirements - Heat & Glo TRUE-36G-IFT Installation Manual

D. Vertical Termination Requirements
Install Metal Roof Flashing
• See minimum vent heights for various pitched roofs
(Figure 7.9) to determine the length of pipe to extend
through the roof.
• Slide the roof 昀氀ashing over the pipe sections extending
through the roof as shown in Figure 7.10.
Note: When installing a silicone or EPDM pipe 昀氀ashing boot
on a metal roof, it is recommended to put a bead of 100%
silicone sealant where the boot contacts the vent pipe to
prevent the entry of water. Follow the manufacturer's recom-
mendations when installing the boot.

NOTICE: Failure to properly caulk the roof 昀氀ashing and
pipe seams could permit entry of water.
• Caulk the gap between the roof 昀氀ashing and the outside
diameter of the pipe.
• Caulk the perimeter of the 昀氀ashing where it contacts the
roof surface. See Figure 7.10.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
