Ignition electrode
The replacement of the electrode is only necessary when the electrode is worn off. This
can be checked by measuring the ionisation current. The minimum ionisation current has
to be higher the 4µA on full load.
If the viewing glass is damaged the complete electrode must be replaced.
Replacement goes as follows:
-

remove the electrical connections of the electrode;

-

press the clips on both sides of the electrode to both sides and remove the complete
electrode;

-

remove and replace the gasket;

Refitting of the components is done in reverse order.

Siphon and condensate tray
-

first remove the condensate cup;
Check this for pollution. If there is no sign of strong pollution it is not necessary to clean
the condense tray. If there is a strong pollution in the cup it is necessary to remove
and clean the condensate tray;

-

check the O-rings of the cup as well as those from the pipe and replace if necessary;

-

clean both part by flushing it with clean water;

-

grease the O-rings again with acid free O-ring grease to make fitting easier;

-

if there is a leak at the siphon cup or tray the complete siphon unit has to be replaced
by S4421200;

-

remove the plug from the flue gas sensor if present;

-

turn the two short clamping rods ¼ turn and remove them by pulling them forward; Note
the right turning direction  (red indicator);

-

lift the flue gas pipe out of the condensate tray;

-

press the condensate tray carefully downwards and remove it by pulling it forward;

-

replace the gasket between condensate tray and heat exchanger by a new one;

-

clean the condensate tray with water and a hard brush;

-

check the condensate tray for leaks.

Refitting is done in reverse order.
Note thate the gasket of the condensate tray seals completely.

Make sure that during refitting of the clamping rods they are put in the right
position. They should be turned vertically.

Alway replace all removed gaskets of dismantled parts during the
maintenance activities.

Put the boiler into
operation and check
the CO

 (see page 30).

Replace the secure
screws A, B, C, D
and E in the quick-
release fasteners
after the
maintenance
activities.
