8-CONNECTIONS
8.1 Flue Connections
8.1.1 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 boiler 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.
