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.
