Parallel flues - The maximum permissible length should be reduced by the equivalent length of each bend. (Note: for a parallel installation this means that changes in direction amount to bends ( in the supply duct and in the flue). - The maximum length also applies if a parallel installation has different supply and flue duct lengths (B2, ). - ombined flues () shall be fitted with a condensate drain. Further information on the flue gas discharge materials can be found in the Installation Manual. Note: horizontal flue runs must be installed with a fall of at least mm per metre.
