The coupling and connection methods may vary depending on
the manufacturer. It is not permitted to combine pipes, coupling
and connection methods from different manufacturers. This also
applies to roof terminal and common shared flue ducts.
The materials used must comply with the prevailing regulations
and standards.

4.5.4
Length of the flue and air supply pipes
The maximum length of the flue and air supply vary per appliance type.
Consult the relevant chapter for the correct lengths.
If a boiler is not compatible with a specific flue system or diameter, it is
indicated with "-" in the table.
When using bends, the maximum flue length (L) must be shortened
according to the reduction table.
Use approved flue reducers for adaptation to another diameter.
The boiler also supports other flue lengths and diameters than those
specified in the tables. Contact us for more information.
