MAINTENANCE
7.1 - MAIN FEATURES
If the boiler is correctly adjusted, it needs very little maintenance. It only needs to be checked once a
year and, if necessary, be cleaned. See the Annual Maintenance Schedule in Table 7-1 at the end of
this section. any case the frequency of the cleaning depends on the cleanliness of the air for the
combustion. Dust presence in the air will find its way into the combustion chamber, will increase
resistance, and will result in a reduced heat input and consequently a reduced output.
Before washing the boiler body sections, check the
boiler input and the CO
2
percentage. If the actual
input (with the correct CO
2
) is within 5% of the
value shown in paragraph 1.5, the boiler does not
need to be cleaned. The operation then can be
limited to the cleaning of the condensate drain.
NOTE:
A reduction of the input can be caused by the obstruction of the flue outlet or of the air intake.
Check, first of all, that this is not the reason.
Disassembly
1. Switch off power and gas supply and
verify that the gas cock is fully closed.
2. Unscrew the union at the gas inlet.
3. Remove the front, rear and top panels of the
boiler.
4. After the removal of
“B”
screws, remove the
cover
“A”
of the fan chamber.
5. Remove the diaphragms
“C”
from the bottom of
the fan chamber to get access to the screws
securing the burner covers.
6. Using a 13 mm socket wrench, remove the
screws
“D1 – D2 – D3 – D4”,
securing the
burner covers.
