Servicing schedule
We recommend that periodical service is made
by qualified technical personnel according to
the frequency stated by national rules in force.
As much as the dust present in the air will be sucked inside the
combustion chamber, the smoke side resistance will increase,
which, nally, will result in a reduced heat input (and conse-
quently a reduced output).
efore cleaning the boiler body sections, check the boiler input
and the CO
2
percentage (see 3.24).
Note! A reduction of the input can be caused
by the obstruction of the evacuation duct or
oftheairintake.Check,rstofall,thatthis
is not the reason.
If the actual input (with the correct CO
2
) is within 5% of the
value shown in the chapter 3.24, the boiler does not need to
be cleaned.The operation then, can be limited to the cleaning
of the siphon.
- Act on the two closing hinges (on both sides) to remo-
ve the cover

tion left and right.
