- In case of a vertical flue pipe
installation, a condensate trap
is fitted at the base of the flue
installation and connected into
drainage system (see Figure 22).
Shaft Connection
Connect the flue to the shaft according
to the following specification:
• Do not allow the flue gas to
protrude inside the shaft; instead
terminate it before it reaches the
shaft.
• The flue gas must be perpendicular
to the opposite wall of the shaft
(see Figure 23).
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 30). 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 31).
