Note #1: In Vent Option #1, the 80/125mm concentric straight section (P/N 101162-01) shown in Table 7.4a may be used
between the boiler and the rst 80/125 x 60/100 reducing elbow. If this is done, the overall maximum vent length is still
restricted to that shown for Vent Option #1 in Table 7.1 above.
