Lengths of the air/flue gas pipes

The maximum lengths (Lmax) given in the table are valid for pipes in
which the horizontal sections do not exceed one metre in total. For each
additional metre of horizontal pipe, a multiplication coefficient of 1.2 must
be applied when calculating the total length L. The total length L is
calculated by adding the lengths of the straight air/flue gas pipes and the
equivalent lengths of the other components.
Always ensure that L is less than Lmax.
Important
For the list of flue gas system accessories and the equivalent
lengths, refer to the current price list.
