Chimney components required to complete installation:
Calculated offset 12 + 9 = 21
Closest possible offset 21%
Chimney components required for offset:

Total height — offset rise = chimney components needed.
21 ft. — 39 in. (3*3" or 3') = 18 ft. height.
From the Vertical Installation Chart Table 2 the sections required are:
1 - F12-8 1 - F18-8 and 3 - F48-8.
