Safety warnings for maintenance

Maintenance of the boiler must be performed at least once a year and should be planned in advance with the Technical
⚠
Assistance Service.
⚠
Dispose of cleaning waste in accordance with the current local regulations
In some conditions, such as turning the boiler on and off or inappropriate use, the combustion products can contain small
soot particles that build up in the smoke evacuation system. This can reduce the cross-section of the smoke duct and pose
⚠
a fire risk. The smoke evacuation system must be inspected and cleaned at least once a year.
The maintenance operations must be carried out when the boiler is cold and with the electrical power supply disconnected.
Before completing any maintenance operation, adopt the following precautions:
• Make sure that all boiler parts are cold.
• Make sure that the ashes are completely cold.
• Always operate with equipment that is appropriate for maintenance.
• When maintenance is finished, re-install all of the dis-assembled parts before restarting operation.
��
The quality of the pellet, the boiler operating mode and combustion control can affect maintenance activity frequency.

Cleaning

��
Perform the cleaning operations so as to guarantee correct boiler operation.
Boiler cleaning is very important to prevent: poor combustion, deposits of ash and unburnt products in the brazier, reduced thermal
efficiency.
The table below lists the necessary cleaning operations required for correct stove operation.
��
It is recommended in the early periods of use of the boiler, or of a new type of pellet, to carry out cleaning operations
frequently, so as to be able to assess the exact frequency of intervention.
Cleaning the ash drawer
The ash drawer must be cleaned every 30 days, (de-
pending on the amount of time the boiler is used and
what type of pellet is used).
