C Further information on the specific flue discharge materials can be found in the installation manual. C Concentric flues It is not permitted to use more than the specified number of bends, even when the duct is shorter than the maximum length. A bend is equivalent to a 90 bend. Parallel flues - he 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). - he maximum length also applies if a parallel installation has different supply and flue duct lengths (B2, C). - Combined flues (C) shall be fitted with a condensate drain. Note: horizontal flue runs must be installed with a fall of at least mm per metre.
