The diagrams of Figure 9 show a few exam-
ples of the permitted exhausts configura-

2.6.2 Connection to existing flues
The ø 80 or ø 60 exhaust pipe can also be
connected to existing flues. When the boiler
runs at low temperature, it is possible to use
standard flues provided that:
- The flue is not be used by other boilers.
- The interior of the flue is protected to pre
-
vent a direct contact with condensation
from the boiler. The products of combu-
stion must be conveyed through a flexible
or rigid plastic pipe around 100 to 150
mm in diameter, and condensation must
be siphoned off at the foot of the pipe. The
