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 dis­
charged via a collector before it reaches the aluminium.
With longer lengths of aluminium flue gas outlet pipes, relatively large
quantities of corrosion products flowing back out of the outlet pipes to­
gether with the condensate must be taken into account the first time.
Clean the siphon of the appliance regularly or install an extra conden­
sate collector above the unit.
Make sure that the flue gas outlet pipe towards the boiler has a sufficient
gradient (at least 50 mm per metre) and that there is a sufficient conden­
sate collector and discharge (at least 1 m before the outlet of the boiler).
The bends used must be larger than 90° to guarantee the gradient and a
good seal on the lip rings.

S Insertion depth 25 mm
Assembly
1. Fit the flue gas outlet pipe and the air supply pipe to the boiler.
2. Fit the successive flue gas outlet pipes and air supply pipes seam­
lessly together.
Caution
The pipes must not be resting on the boiler.
Fit the horizontal parts sloping down towards the boiler, with a
gradient of 50 mm per metre.

Danger of electric shock
The following components of the boiler are connected to a 230 V
power supply:
Electrical connection to circulating pump.
Electrical connection to gas combination block.
Electrical connection to fan.
Control unit.
Ignition transformer.
Power supply cable connection.
The boiler has a three-wire mains lead (lead length 1.5 m) and is suitable
for a 230 VAC/50 Hz power supply with a phase/neutral/earth system. The
boiler is not phase sensitive. The power supply cable is connected to the
X1 connector. A spare fuse can be found in the housing of the control unit.
