Figure 9. Connector rise
Figure 10. Suggested venting system constructions
Connector Rise: Connector rise is the length of the pipe connecting the
top of the draft hood to the system breeching above. The diameter of this
pipe varies depending upon BTU input, chimney height and the length of
the connector. Fig.9 (Dim. "B") shows the location of this pipe in a typical
application. Table 2a depicts the proper diameter (Dim. "C") of the connec-
tor rise depending upon its total length (top of the draft hoods to the
breeching above).
