For each component, tables 4 - 5 provide an “equivalentloss in linear metres”, depending on the positionof installation of the component (with air intake or flueextraction, vertical or horizontal).The loss is called “equivalent length” since it is comparedto the loss of one metre of flue (defined as equal to 1).For example, a bend at 90° of Ø80 in flue extraction hasan equivalent loss of 2 linear metres, i.e. it has a lossequal to that of 2 linear metres of flue length.1KWMA84U5330fig. 182. After completely defining the layout of the system of splitflues, add up the losses in equivalent metres, dependingon the installation position, of all the components andaccessories in the system.1KWMA82U3. Check that the total calculated loss is less than or equalto 55 equivalent metres, i.e. the maximum permissiblefor this model of boiler.For complete flue options please contact ferroli orcheck our comprehensive flue manual.1KWMA83WTable 3Ref.DescriptionEquivalentloss42241815Vertical air pipe Ø80Vertical flue pipe Ø8018 m24 m1KWMR54A5180 Ø vertical flue Kit12 mTotal54 mfig. 19Cod. 3540F441 - 03/2007 (Rev. 01)19
