A. Chimney Requirements
Vertical distances are measured from the base of the re-
place.
• Minimum overall straight height is 6 ft 4 in. if the replace
is freestanding and a minimum of 10 ft from a combustible
structure. See Figure 3.2.
• Chimney must extend 2 ft (.6 m) above any portion
of the roof within 10 ft (3 m) of the chimney. Refer to
Figure 6.1.
To determine the chimney components needed to complete
your particular installation, follow the steps below:
• Determine the total vertical height of the fireplace
installation. This dimension is measured from the base of
the replace assembly to the point where the smoke exits
the termination cap.
• Subtract the effective height of the replace assembly from
the overall height of the replace installation (measured
from the base of the fireplace to the bottom of the
termination cap).
• Refer to Table 5.1 to determine what components must
be selected to complete the replace installation.
• Determine the number of ceiling restops, stabilizers,
roof flashing, etc. required to complete the fireplace
installation.
