MAXIMUM FLUE LENGTH = 7 m *
The flue length is the total length of the flue

The total length is calculated by summing
the lengths of all the straight section AND
the equivalent lengths of each bend (see

Ø 80/125 x 90° bend = 0.8 m
Ø 80/125 x 45° bend = 0.5 m
* If a flue length of above 7 metres is
required, use the Twin Pipe system.
