4 Installation
Concentric systems made of plastic (diameter - 80/125
mm) are combined with the appliance as flue pipes. The
most suitable system depends on the specific installa-
tion and application conditions (see also the installation
manual 83 44 49 for the flue pipes).
• Mount the flue pipes consulting the installation manu-
al contained in the scope of delivery of this appliance.
4.7 Condensate
discharge
The condensate generated during combustion is led
from the condensate discharge pipe to the waste water
connection via a draining funnel.
Caution!
The condensate discharge pipe may not be con-
nected tight to the waste water line.
• Connect the supplied condensate discharge hose (1) to
the pre-installed draining funnel (2).
The draining funnel also serves to drain off any heating
water that may be escaping at the safety valve.
If the condensate discharge line needs to be extended
during installation, only use DIN 1986/EN 12056 compli-
ant drain pipes.

4.8 Electrical
connection
Danger!
Risk of fatal electric shock from touching live
connections. Always switch off the power sup-
ply to the boiler first. Only once this is done
may you carry out the installation.
There is continuous operating voltage at the
power supply terminals L and N even when the
main switch is switched off.
4.8.1 Mains
connection
Caution!
Supplying power to false plug terminals of the
Pro E system can destroy the electronics.
Only connect the mains supply to the terminals
that are marked as being for that purpose.
The rated voltage of the mains must be 230 V; at rated
voltages above 253 V and under 190 V, functional im-
pairments are possible.
The mains supply must be connected via a fixed connec-
tion and a separator with a contact opening of at least
3 mm (e.g. fuses, circuit breakers).
4.8.2 Connecting
controllers
Mounting is to be carried out as instructed in the rele-
vant installation manual. The necessary connections to
the boiler‘s electronics (e.g. when using external control-
lers, external sensors or similar devices) are to be per-
formed as follows:
• Take off the front casing of the appliance and lift the
electronics box (1) forward.
• Unclip the back cover (2) of the electronic box from its
fixings (3) and lift it up.
• Guide the connecting cables of each of the compo-
nents to be connected through the cable routes (4) lo-
cated on the bottom of the appliance to the left.
