17 Siphon/neutralisation/condensate
pump
For standard fuel oil EL (sulphur content > 50 ppm),
neutralisation of the condensate is required.
The neutralisation box must be filled with water
prior to commissioning! This checks whether
all connections are assembled in a sealed way.
Operating the device with a leaking connection
from the neutralisation box carries a risk of waster
damage from the leaking condensate.
Observe the neutralisation box installation
instructions.
Note
If low sulphur fuel oil EL (sulphur content < 50 mg/kg) is used, it
may be possible to forego neutralisation of the condensate after
consultation with the lower water authority.
The condensate may only be drained in drain lines in
accordance with Code of Practice DWA-A251.
Neutralisation is still required if the condensate has not been
mixed with sufficient non-domestic waste water (at least 20 times
the volume of the expected amount of condensate).
After removal of the cover, connect the supplied trap to the
connectors on the combustion chamber pan.
The sealing plugs located on the trap sealing
plugs must be removed before assembly of
the trap, so that the condensate can freely flow
through the trap. Otherwise, this leads to an
operating fault.
With a flexible trap drain hose, form a connection from to the
on-site drain with a continuous slope (condensate drain level
from trap 260 mm).
When using a condensate pump, route the flexible trap drain
hose into the condensate pump and form a connection there to
the on-site drain.
The trap must be filled with water prior to
commissioning. Operating the appliance with
an empty trap presents a risk of poisoning or
asphyxiation due to the escape of flue gases.
Undo the trap, remove and fill until water runs
out of the drain hole on the side. Refit the trap
and ensure the gasket seals tightly.
If condensate is directly routed to the on-site drain, ventilation
must be provided so that the drain pipe cannot affect the boiler.
