Vertical distances are measured from the base of the fire-
place.
• Minimum overall straight height is 10 ft. if the fireplace is
freestanding and a minimum of 10 ft from a combustible
structure.
• Chimney must extend 2 ft (.6 m) above any portion of the
roof within 10 ft (3 m) of the chimney. 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 fireplace assembly to the point where the smoke exits
the termination cap.
• Subtract the effective height of the fireplace assembly from
the overall height of the fireplace 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 fireplace installation.
• Determine the number of ceiling firestops, stabilizers,
roof flashing, etc. required to complete the fireplace
installation.
