Pipe lengths in the B23P installation
Note
The maximum pipe length (straight pipe only) corresponds to the maximum permitted flue gas pipe length without
any elbows. If elbows are used, the maximum pipe length must be reduced in accordance with the dynamic flow
characteristics of the elbows. Elbows must not be connected directly after one another as this method dramatically
increases pressure losses.
