* 6 in / 8 in Vent System:
Horizontal vent pipe size 6 in (150 mm)
Vertical vent pipe size 8 in (200.00 mm).
Length between vertical vent pipe and last horizontal vent collector pipe = 3 ft 4 in (1.00 m).
For calculating other lengths between the last collector and the shaft, the length of the vertical height must be reduced by this additional length
and by the numbers of bends according to the table.
