Determine the chimney components needed to complete
your particular installation:
• Measure the total vertical height of the fireplace
installation from the base of the fireplace assembly to
the approximate location of the bottom of the termination
cap.
• Subtract the effective height of the fireplace assembly
(see Figure 4.1) from the total vertical height to determine
the overall height of the chimney installation.
• Create a schematic for your application similar to Figure
4.1 showing components required (referring to Table 4.1).
• Install a ceiling firestop whenever the chimney penetrates
a floor/ceiling.
NOTICE:
A maximum of two offset and return may be
used.
