1.4 Switching on and off
Ignition
Check that any external system shut-off valves are open. Open the gas cock ahead of the generators, turn
the main switch ON and press the ignition keys on the control panel. The boiler will run a self-test cycle
of approx. one minute, after which it is ready for operation. The burner switches on and off completely
automatically depending on system heat demands.
Switching off
In case of prolonged idle periods, close the gas cock ahead of the generators and disconnect the power
supply. In this case, also the boiler antifreeze protection, which switches on the burner for system tempera-
tures below 5°C, is deactivated.
Dangers of freezing
The best protection during extremely cold periods is to keep the boiler and users working so that
the entire system is involved. Alternatively, add antifreeze fluid to the system water, in the amount
recommended by the supplier according to the presumed minimum ambient temperature.
1.5 Anomalies
In case of operation problems or anomalies, the control unit of the single boiler shell activates flashing of
the corresponding display (with fault identification code) and a 230Vac output (to which a visual or acoustic
signalling device can be connected. See the electrical connections section).
Faults marked with the letter
“F”
cause temporary shutdowns that are automatically reset as soon as the
value returns within the generator’s normal working range.
Faults marked with the letter
“A”
cause a permanent generator shutdown resettable by the user. To restore
operation, press the
key (reset).
If the problem persists, or for any other trouble, refer to the “troubleshooting” section in this manual for
further details and, if necessary, request the intervention of Qualified Personnel or the assistance centre.
In case of appliance fault and/or poor operation, switch it off, and do not make any attempt to repair
it or directly intervene. Contact authorized and professionally qualified personnel.
