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.

Note: A maximum of two pairs of offsets and returns may be used.
