7.6.13 About securing the flue system
CAUTION
▪ These regulations are typical for both concentric and parallel flue systems.
▪ The flue system MUST be secured to a solid structure.
▪ The flue system should have a continuous fall back to the boiler (1.5°~3°). Wall
terminals MUST be installed levelled.
▪ Only use accompanying brackets.
▪ Every elbow MUST be secured by using the bracket. Exception at connecting on
boiler: if the length of the pipes before and after the first elbow is ≤250mm, the
second element after the first elbow has to contain a bracket. The bracket MUST
be positioned on the elbow.
▪ Every extension MUST be secured per meter with a bracket. This bracket MUST
not be clamped around the pipe ensuring free movement of the pipe.
▪ Make sure that the bracket is locked into the correct position depending on the
position of the bracket on the pipe or elbow.
▪ Do NOT mix flue parts or clamps of different suppliers.
