CLEANING AND MAINTENANCE

Carry out the cleaning of the generator in
the following way:
– Remove the electricity supply to the boi-
ler and close the gas supply cock.
– Dismantle the casing as described in
point 4.6.
– Dismantle the burner - gas manifold
group (fig. 27).
– To clean direct a stream of air towards
the inner part of the burner to blow out
any dust that has accumulated.
– Then clean the heat exchanger removing
dust and combustion deposits.
– In cleaning the heat exchanger and that
of the burner, chemical products or steel
brushes must never be used.
– Make sure that the top perforated part
of the burners is free of encrustations.
– During the assembly and disassembly of
the burner it is recommended that
attention be paid to the ignition and

4.7. 1
To carry out the verification of combustion
in the boiler, turn the selector and stop on
the position ( ) until the yellow led (
starts to flash intermittently (fig. 29).
From that moment the boiler will start
functioning in heating mode at the maxi-
mum power (20,000 - 25,000 kcal/ h),
with switching off at 80°C and restarting
at 70°C.
Before activating the chimney sweep func-
tion make sure that the radiator valves or
eventual zone valves are open.
The test may be carried out also during hot
water functioning.
To do so it is enough, after having activated
the chimney sweep function, to take some
hot water from one or more cocks; after a
few minutes the request of the D.H.W. sen-
sor is activated and it automatically swit-
ches on the led (
Even in this condition the boiler functions at

the maximum temperature always with the
primary controlled between 80°C and 70°C.
During the entire duration of the testing the
hot water cocks must remain open.
After verifying the combustion the boiler
should be switched off by placing the selec-
tor on the OFF position; then return the
selector to the desired function.
ATTENTION:
After about 15 minutes the chimney
sweep function automatically deactivates.
