Condensation
Direct connection of the flue gas outlet to structural ducts is not
permitted because of condensation.
If condensate from a plastic or stainless steel pipe section can flow back
to an aluminium part in the flue gas outlet, this condensate must be
discharged via a collector before it reaches the aluminium.
Newly installed aluminium flue gas pipes with longer lengths can
produce relatively larger quantities of corrosion products. Check and
clean the siphon more often in this case.

Requirements for the electrical connections
Establish the electrical connections in accordance with all local and
national current regulations and standards.
Electrical connections must always be made with the power supply
disconnected and only by qualified installers.
The boiler is completely pre-wired. Never change the internal
connections of the control panel.
Always connect the boiler to a well-earthed installation.
The wiring must comply with the instructions in the electrical diagrams.
Follow the recommendations in this manual.
Separate the sensor cables from the 230 V cables
Make sure the following requirements are met when connecting the cables
to the CB and SCB connectors:
Tab.17 PCB connectors
Wire cross section
Stripping length
Tightening torque
solid wire: 0.14 – 4.0 mm² (AWG 26 – 12)
stranded wire: 0.14 – 2.5 mm² (AWG 26 – 14)
stranded wire with ferrule: 0.25 – 2.5 mm² (AWG 24 – 14)
8 mm
0.5 N⋅m

Water quality and water treatment
The quality of the heating water must comply with the limit values in our
Water quality instructions. The guidelines in these instructions must be
followed at all times. In many cases, the boiler and central heating system
can be filled with normal tap water and water treatment will not be
necessary.
