Can someone please explain the difference in these pictures?? I understand chimney height requirements but am confused about fuel vents and flue pipes minimum height.
One picture shows 3 feet, one says 2 feet, and the chart shows 1 foot.
Also chapter 3 of the inspecting roofing course says “It is a common mistake to apply chimney termination-height requirements (3-2-10 rule) to fuel vents, which cause vents to extend above roofs much higher than needed.” The rules seems conflicting. Any help would be appreciated.
