Condensed water forms during combustion. The condensed
water discharge pipe routes this condensed water to the
waste water connection via a tundish.
▶
Use PVC or another material that is suitable for draining
the non-neutralised condensed water.
▶
Only use corrosion-resistant piping material for removing
condensate.
▶
If it cannot be guaranteed that the materials are suitable,
install a system for neutralising the condensed water.
▶
Connect the condensed water discharge pipe
(1)
to a
suitable drain siphon
(2)
.
▶
Ensure that the condensed water in the drain line is
drained properly.

Solar connection
5.5.1
General information
Caution.
Risk of voltage surge.
Overvoltage may damage the solar plant.
▶
Earth the solar circuit to provide equipo-
tential bonding and overvoltage protec-
tion.
▶
Secure earthing pipe clamps to the solar
lines.
▶
Connect the earthing pipe clamps to a
busbar using 16 mm
²
copper cable.
Note
If there is a fault in the solar system or if the solar
system is connected at a later point, this unit can
be used without being connected to the solar cir-
cuit.
In this case, set diagnostics code d.200 to 1.
▶
Ensure that the heat insulation of the lines is sufficient to
prevent excessive heat losses.
–
The outside lines are exposed to the weather and ul-
traviolet radiation and are pecked by birds, making
them particularly vulnerable; select effective protec-
tion against these risks.
▶
Maintain a minimum downward gradient in order to guar-
antee automatic draining of the solar circuit.
–
Minimum downward gradient that is to be maintained:
4 %
▶
Solder all of the pipelines.
▶
Do not use plastic pipes.
▶
Only use press connections if the temperature that is
permitted by the manufacturer is 200 °C.
Conditions
: The building has a lightning conductor.
▶
Connect the solar collectors to the lightning conductor.
5.5.2
Material for the solar pipes
Caution.
Risk of material damage caused by mech-
anical deformation or burst lines.
Due to the extremely high temperatures that
the solar fluid can reach from time to time,
plastic lines (e.g. PE pipe) may deform or
burst.
▶
Do not use plastic lines.
▶
It is preferable to use copper pipes.
Selecting a suitable line diameter has a great influence on
the solar system's efficiency. The system works with a hose
with an internal diameter of 8 mm.
5.5.3
Maximum length of the solar pipes
Note
To prevent energy losses, the hydraulic lines must
be provided with heat insulation that complies with
the applicable thermal insulation regulations.
