Calculation example
Pipe Pipe lengths
Flue gas outlet L1 + L2 + L3 + 2x2 m
Air supply L4 + L5 + L6 + 2x2m
Note:
The total pipe length is: sum of the straight pipe lengths + sum of the replacement pipe
lengths of bends/knees amounts to a total of 25 meters. If this value is less than the
maximum permitted pipe length, the flue gas outlet meets the requirements on this point.
