REMOVAL OF OUTER CASING

It is possible to completely disassemble
the shell for an easy maintenance of the
boiler following these simple instructions
(fig. 27):
– Remove the two screws locking the front
panel to the sides.
– Pull the front panel (5) forwards so as to
release it from the slot-in pins located on
the sides.
– Unscrew the two screws fixing the instru-
ment panel to the sides.
– Unscrew the four screws fixing the sides
to the instrument panel support.
– Push the sides (3) and (4) upwards, sli-
ding them out of their slots.
4.4 CLEANING AND
MAINTENANCE
Preventive maintenance and checking of
efficient operation of equipment and safety
devices must be carried out exclusively by
authorized technical personnel.
During maintenance operations the
authorised technician must check that
the syphened drip is full of water (this
check is of importance particularly when
the generator has been out of use for a long
period of time). Filling is done via the special
opening (fig. 28).
4.4. 1

Chimney sweep function

To carry out the verification of combustion
in the boiler, turn the selector and stop on
the position ( ) until the orange led (
starts to flash intermittently (fig. 29).
From that moment the boiler will start func-
tioning in heating mode at the maximum
power, with switching off at 80°C (176 °F)
and restarting at 70°C (158°F).
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
Fig. 28
or more taps; after a few minutes the
request of the hot-water service feeler is
activated and it automatically switches on
the led ( ).
Even in this condition the boiler functions at
) the maximum temperature always with the
primary controlled between 80°C (176 °F)
and 70°C (158°F).
During the entire duration of the testing the
hot water taps must remain open. After
verifying the combustion the boiler should
be switched off by placing the selector on
the (OFF) position; then return the selector
to the desired function.
ATTENTION: After about 15 minutes the
chimney sweep function automatically
deactivates.
