A. Chimney Requirements
Vertical distances are measured from the base of the
fi
re-
place.
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
fi
replace assembly to the point where the smoke exits
the termination cap.
• Subtract the effective height of the
fi
replace assembly from
the overall height of the
fi
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
fi
replace installation.
• Determine the number of ceiling
fi
restops, stabilizers,
roof flashing, etc. required to complete the fireplace
installation.
Table 5.1
