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 45° bend is equivalent to a 90° bend. Parallel flues - The maximum permissible length should be reduced by the equivalent length of each bend. (Note: for a parallel installation this means that 3 changes in direction amount to 6 bends (3 in the supply duct and 3 in the flue). - The maximum length also applies if a parallel installation has different supply and flue duct lengths (B23, C53). - Combined flues (C43) shall be fitted with a condensate drain. Note: horizontal flue runs must be installed with a fall of at least 5 mm per metre.
