4.9 Flue Connection
In order to ensure that the appliance functions correctly and efficiently,
the flue connection between the boiler and the flue terminal must be
made using original components specifically designed for condensing
boilers.
Traditional flue components cannot be used for conveying exhaust
fumes from condensing boilers, nor vice versa.
• Below suggestions must be taken into consideration for flue installation:
- Horizontal air intake pipes must slope downwards by 3° at the wall towards
atmosphere to prevent the entry of rain water, dust or impurities to the pipe.
For horizontal flue gas pipes, situation is different. Flue gas pipes must
slope upwards by 3° to facilitate the flow of condensate water in flue back
to combustion chamber, to prevent the stalactite formation by freezing in
winter and the risk of drop and hurting to walking people (Figure 20). In case
of horizontal concentric flues, flue gas pipe (inner pipe) must slope upwards
whereas air intake pipe (outer pipe) must slope downwards. Horizontal
concentric flue set must be installed parallel to floor. After installation
horizontally, flue gas pipe stands slopped upwards by itself as a result of
special design (Figure 21).
