Danger!
Risk of poisoning from leaking flue gas!
If the device is operated with an empty conden-
sate 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) 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 gas-fired condensing boilers up to 200 kW:
If required, a neutralisation device with conden-
sate feed pump from the Vaillant range of ac-
cessories can be connected.
For gas-fired condensing boilers above 200 kW:
If required, an in-line neutralisation device from
the Vaillant range of accessories can be con-
nected.

Danger!
Risk of fatal electric shock from live connec-
tions!
The electrical installation must be carried out
by an authorised qualified electrician, who is re-
sponsible for complying with the existing
standards and guidelines. All electrical work
must be in accordance 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. Voltage is continuously
present on the L and N terminals of the tur-
quoise coloured plug, 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, Fig. 2.2) must be
guaranteed at all times and must not be cov-
ered or blocked, so that the appliance can be
switched off in the event of a malfunction.
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.

Danger!
Danger of death from electric shock!
The fan is connected to a 230 V/50 Hz supply.
The connection should be wired as follows:
• Open the front flap by lifting the silver handle strip.
• Unscrew the screw above the multi-function operating
panel.
• Pull the front casing in the upper section towards you
and lift it in order to remove it.
• Hinge the electronics box forward.
• Unhitch the rear part of the electronics box cover and
hinge it upwards.
• Pass the cables through the cable entry in the rear
wall of the appliance and through the unit into the
electronics box.
