7- FLUES
7.1- Flue Sizes
Flue gas connections between the boiler and the flue terminal must be made using original components
specially designed for the condensing boiler to ensure that the device operates efficiently and correctly.
Flue gas pipes and fittings of non-condensing boilers can not be used for exhausting gases from
condensing boilers. In the horizontal concentric flues, the exhaust gas pipe (the inner pipe) facing
outwards should be inclined upward and the fresh air pipe (outer pipe) should be inclined downward.
When the original flue set is installed parallel to the ground, the exhaust gas pipe is automatically
inclined upwards.
Equivalent length for each 90° elbow: 1 m
Equivalent length for each 45° elbow: 0.5 m
7.2- Flue Types
The terminals for the supply of combustion air and for the evacuation of combustion products shall not
be installed on opposite walls of the building. Information for C43 flue type is given below.
