Vertical distances are measured from the base of the re-
place as shown in Figure 8.2
To determine the chimney components needed to complete your
particular installation, follow the steps below:
• Determine the total vertical height of the replace 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 replace to the bottom of the termination cap, 13 ft.
(4m).
• Refer to Table 8.1 to determine what components must be
selected to complete the replace installation.
• Determine the number of ceiling firestops, stabilizers, roof
ashing, etc. required to complete the replace installation.
