Danger!
Risk of poisoning from leaking flue gas!
If the device is operated with an empty
condensate siphon, there is a risk of poisoning
from the escaping flue gases. Be absolutely
certain, therefore, to fill the siphon before
starting up.
Connecting the condensate drain
The chimney drainage line is run on a slope using suita-
ble plastic or stainless steel piping with a minimum
cross-section of DN 20. The condensate water piping to
the waste outlet is also installed at an angle using a
DN 25 pipe (plastic or stainless steel) and must go to
the nearest waste water outlet. The take-off from the
boiler is effected by means of a ø 21 mm plastic pipe.
The discharge point must remain visible.

Note!
For boilers up to 200 kW:
If required, a neutralisation device with
condensate feed pump from the range of
Vaillant accessories can be connected.
For boilers above 200 kW:
If required, an in-line neutralisation device from
the range of Vaillant accessories can be
connected.

Danger!
Risk of fatal electric shock from live connec-
tions!
The electrical installation must be carried out
by an electrical specialist, who is responsible
for complying with the existing standards and
guidelines. All electrical work must be in ac-
cordance with the Electricity at Work Act and
BS 7671.
Danger!
Risk of fatal electric shock from live connec-
tions!
•
Always switch off the power supply to the
appliance first. Only after this can the instal-
lation be carried out. Continuous voltage is
present on the L and N terminals, even when
the main switch is turned off.
Danger!
Risk of fatal electric shock from live connec-
tions!
Mains and low-voltage cables (e.g. sensor wir-
ing) must be run separately from each other.
Use the divided cable channel on the left hand
side section for this.
a
Caution!
Access to the main switch (4) (see Fig. 2.2)
must be guaranteed at all times and must not
be covered or blocked, so that the appliance
can be switched off in the event of a malfunc-
tion.
To simplify the wiring, the appliance is equipped with
System ProE connectors and is ready for connecting.
The mains cable and all the other connecting cables
(e.g. from the room thermostat) can be connected to
the System ProE plugs that have been provided in each
case.
