Installation Instructions Model TLC All-Fuel Chimney
Chart 2 - CHIMNEY HEIGHT ABOVE THE ROOF
Requirement #1: The code requires that the chimney must extend at least 3 feet above the highest point of
the roof that it penetrates.
Requirement #2: The chimney must also be 2 feet above any roof, wall, or other obstruction within a
horizontal distance of 10 feet.
The following chart is provided to assist you in determining the minimum chimney height required above the roof.
You may need to add to this height, as nearby buildings, trees, and other parts of the house roof could interfere
with airflow over and around the top of the chimney and affect its performance. If you think a nearby obstacle
could affect draft, you might want to install one or more additional lengths.
