5.14.3.5 Installing the 87° elbow, 80/125 mm diameter
A Offset B Length of the air pipe
▶ Measure the offset (A), e.g. with 400 mm.
▶ Use this value from the table to determine the length of the air pipe (B) = 200 mm.
◁ From that, the corresponding flue pipe length is calculated as 200 + 40 = 240 mm
