Condensate drain connection
Connect the trap supplied to the connector on the combustion
chamber pan.
Note:
Fill the trap with water prior to commissioning.
If condensate is directly routed to the drain pipe, ensure ventila-
tion, so that the drain pipe cannot affect the condensing boiler.
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.
The condensate must only be routed through pipes that are
resistant.
Observe the relevant instructions if you install a neutralising
system (accessory).
Condensate pump
When using a condensate pump, the alarm output can be con-
nected at connection E1. Set the boiler parameter HG13 to "2".
The alarm output switches the appliance OFF if condensate
cannot be pumped out correctly.
