1.3.4. Shut-down due to inadequate air/flue gas draught
Should the boiler shut down due to air intake and/or flue gas discharge ducts malfunction, no. 4 LED (pic. 1) starts flashing. Should that
happen, contact an authorized Service Centre or qualified personnel for service.
1.3.5. Shut-down due to fan malfunction
Fan operation is constantly monitored and in case of malfunction the burner is turned off and no. 3 and no. 8 LEDs (pic. 1) start flashing
simultaneously.
The above status continues until correct fan operation is restored.
Should the boiler not re-start and still remain in the above status, contact an authorized Service Centre or qualified personnel for service.
1.3.6. Flow alarm
Should flow temperature rise above 85°C, no. 7 LED (pic. 1) start flashing and the burner is turned off.
Normal boiler operation will be restored once flow temperature decreases below 85°C.
1.3.7. Alarm due to failure of temperature probes
Should the temperature probes malfunction, the following LEDs turn on:
- no. 2 and no. 8 LEDs start flashing simultaneously when flow probe malfunction occur;
- no. 2 LED start flashing when DHW probe malfunction occur (KC);
- no. 2 and no. 8 LEDs start alternatively flashing when external cylinder probe malfunction occur (KR equipped with external cylinder).
Contact an authorized Service Centre or qualified personnel for service.
1.3.8. Alarm due to remote control malfunction
Should the boiler receive incorrect information from the OpenTherm remote control (optional equipment), or should it not receive any
(due to remote control malfunctioning, or incorrect connection between the boiler and the remote control), no. 2 and no. 8 LEDs start
flashing simultaneously.
Contact an authorized Service Centre or qualified personnel for service.
1.4. Maintenance
Have the boiler routinely serviced, following the schedule described in the relevant section of this manual.
Appropriate boiler maintenance ensures efficient operation, environment preservation, and safety for people, animals and
objects.
Qualified personnel only are to service the boiler.
Manufacturer recommends Customers to contact authorized Service Centre for maintenance and repairs; they are best qualified
to implement such procedures.
1.5. Notes for the user
The user may only access boiler parts that can be reached without using technical equipment and/or tools: the user is not authorized to
remove boiler casing and operate on any internal part.
No one, including qualified personnel, is authorized to modify the boiler.
The manufacturer shall not be held responsible for damage to people, animals, or property due to tampering or improper intervention to
the boiler.
Should the boiler be left inactive for a long time and power main supply disconnected, the pump might need to be un-blocked.
Such servicing includes boiler casing removal and access to boiler internal parts, therefore only qualified personnel may perform it.
Pump blockage may be avoided by adding filming additives suitable for multi-metal systems to water.
