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.
