Bends should be viewable from both directionswhere the inspection hatch cannot be positioned at the bend.Where suitable access is not provided the appliance must NOT becommissioned and must be disconnected from the gas supply.Additionally the entire flue and all flue seals must be installed inaccordance with the requirements of BS5440:▪ Check if the condensate trap is filled with water and correctlyconnected to the boiler.▪ All flue joints are correctly made, unstressed and adequatelysupported.▪ All parts of the flue can be visually inspected. Ensure suitableaccess where flue is positioned within voids.6.8.12 Flue gas materials (C63) available on themarketThe properties of the combustion determine the choices for the fluematerial. The standards EN 1443 and EN 1856‑1 provide thenecessary information for choosing the flow material by means of asticker including an identification string. The identification stringcontains the following information:0000PY: 2017EN 14471 : 2013 T120 H1 W 1/2 O(00) LE E U00000PY: 2017EN 14471 : 2013 T120 H1 W 1/2 O(00) LE E U0bcdefaa CE markingb In case of metal, the standard must comply to EN 1856‑2.In case of plastic, the standard must comply to EN 14471The identification string needs to contain the following information:c Temperature class: T120d Pressure class: Pressure (P) or high pressure (Hi)e Resistance class: Wet (W)f Resistance class in case of fire: EDimensions C63 of the flue system (external dimensions in mm)Parallel Concentric 80/125 Concentric 60/100Flue pipe Air inlet Flue pipe Air inletØ80(+0.3 / –0.7)Ø80(+0.3 / –0.7)Ø125(+2 / –0)Ø60(+0.3 / –0.7)Ø100(+2 / –0)WARNINGFlue materials of different markings must NOT becombined.6.8.13 About securing the flue systemCAUTION▪ These regulations are typical for both concentric andparallel flue systems.▪ The flue system MUST be secured to a solid structure.▪ The flue system should have a continuous fall back tothe boiler (1.5°~3°). Wall terminals MUST be installedlevelled.▪ Only use accompanying brackets.▪ Every elbow MUST be secured by using the bracket.Exception at connecting on boiler: if the length of thepipes before and after the first elbow are ≤250 mm, thesecond element after the first elbow has to contain abracket. The bracket MUST be positioned on theelbow.▪ Every extension MUST be secured per meter with abracket. This bracket MUST not be clamped around thepipe ensuring free movement of the pipe.▪ Make sure that the bracket is locked into the correctposition depending on the position of the bracket on thepipe or elbow.▪ Do NOT mix flue parts or clamps of different suppliers.
