CHIMNEY HEIGHT REQUIREMENTS
(Above the Roof Line)
Major building Codes specify a minimum chimney height
above the roof top. These specifications are summarized
in what is known as the "Ten Foot Rule". This rule states:
If the horizontal distance from the side of the chimney to
the peak of the roof is 10 feet or less, the top of the chim-
ney must be at least 2 feet above the peak of the roof, but
never less than 3 feet in overall height above the highest
point where it passes through the roof. See Figure 9.
If the horizontal distance from the side of the chimney to
the peak of the roof is more than 10 feet, a chimney
height reference point is established on the surface of the
roof a distance of 10 feet from the side of the chimney in a
horizontal plane. The top of the chimney must be at least
2 feet above this reference point, but never less than 3
feet in height above the highest point where it passes
through the roof.
These chimney heights are necessary in the interest of
safety and do not ensure smoke-free operation. Trees,
buildings, adjoining roof lines, adverse wind conditions,
etc., may create a need for a taller chimney should smok-
ing occur.
DETERMINING THE NUMBER OF CHIMNEY
SECTIONS REQUIRED
To determine the chimney components needed to com-
plete your particular installation, follow the below steps:
1. Determine the total vertical height of the fireplace
installation. This dimension is measured from the
base of the firebox assembly to the point where the
smoke exits the terminal cap.
2. Subtract the height of the firebox assembly (41
from the overall height of the fireplace installation.
3. Refer to the chart on the right to determine what com-
ponents must be selected to complete the fireplace
installation.
4. Determine the number of firestop spacers, stabilizers,
roof flashing, etc. required to complete the fireplace
installation.
