Automatic cleaning system

The main characteristic of this model is the automatic cleaning of the firepot. Consequently there is no more need to clean the firepot
periodically or at every start of the boiler.

! IMPORTANT

Cleaning the fume extractor and combustion chamber

The combustion chamber must be cleaned at least once a year, removing all combustion residuals from the internal fume pipes
and flueways. To carry out this operation, it is necessary to remove the boiler top cover, the heating chamber cover and the bottom
inspection door, undoing the respective fixing screws, then clean the turbulators and internal fume pipes.
Also, make sure to clean the fume extractor located at the back of the bottom fume manifold accessed through the inspection door
opening behind the ash box.
Every 3-4 months clean the inside walls of the combustion chamber and top fume manifold using suitable equipment (brushes) and
replace the vermiculite walls if necessary.
Every 1800 hours of operation or 2000 Kg pellet by means of a message 'SERVICE DUE', the boiler signals the need for extraordinary
maintenance (not under warranty) to be performed by qualified personnel who will carry out complete cleaning and reset the message.
Any knocking or forcing can damage the fume extractor, making it noisy during
operation; therefore it is advisable to have this operation carried out by qualified personnel.

Cleaning the air flow meter

The air flow meter (it measures the flow of combustion air) installed inside the inlet pipe requires periodical internal cleaning every 3-4
months, using suitable equipment (blowing compressed air or suitable brushes).

Cleaning the flue - flue connection

The flue connection must be cleaned at least once a year or whenever necessary.
Cleaning requires the suction and removal of the residuals in all the vertical and horizontal sections as well as the bends from the
unit to the flue.
It is advisable to also clean the flue every year, to ensure correct and safe evacuation of fumes.

Cleaning the exchanger with turbulator-shaker device

The fume ducts inside the heating chamber must be cleaned at least once every 2-3 days by operating the two knobs repeatedly with
an upward and downward movement.
