– remove the four screws (3) and remove the front panel (4)
from the combustion chamber (6) working carefully so as not
to damage the gasket or the panel insulation

Cleaning the burner

The burner does not require any particular maintenance simply
dust it with a soft brush.
4.3.3

Checking the ignition/detection electrode

Check the state of the ignition/detection electrode and replace
if necessary. Check the measurements as per the drawing
whether the ignition/detection electrode is replaced or not.
m
CAUTION
The position of the electrode is essential for the correct
detection of current ionization.
After having cleaned the heat exchanger and the burner:
– remove any carbon residue using a vacuum cleaner
– check that the gasket and the insulation of the front panel (6)
of the combustion chamber and the gasket (13) of the front
panel (4) of the sealed chamber are all integral. If they are
not, replace them
– refit the panels (6) and (4) securing them with fastening
screws.

Final operations

After having cleaned the heat exchanger and the burner:
– remove any carbon residue using a vacuum cleaner
– check that the gasket and the insulation of the front panel (6)
of the combustion chamber and the gasket (13) of the front
panel (4) of the sealed chamber are all integral. If they are

Checks

4.4.1

Checking the smoke duct

It is recommended that the user checks that the combustion air
inlet duct and smoke outlet duct are integral and airtight.
4.4.2

Checking the expansion vessel pressure

It is recommended that the expansion vessel on the water side
is drained and that the prefilling pressure is not less than 1 bar .
If this is not the case, pressurize it to the correct value (see
sectionExpansion vessel".
Once the checks described above have been completed:
– refill the boiler as described in section "REFILL operations"
– start the boiler up and carry out a smoke analysis and/or
measure the combustion efficiency.
– refit the front panel securing it with the two screws which
were removed previously
