CLEANING
Cleaning the brazier - brazier holder
Remove the brazier and the ash deposited in the combustion chamber and brazier holder. A suitable vacuum cleaner may be used for
this purpose. This operation must be carried out daily, especially in case of accumulated unburnt matter, to ensure perfect combustion
conditions, since the brazier holes allow the flow of combustion air.
Also make sure the secondary air holes in the side pipes of the brazier holder are free of any combustion residuals and ash.
When necessary, clean the fire door glass for visually checking the flame inside the combustion chamber.
Brazier dirty
The brazier must rest on the brazier holder and precisely on the entire ring band without air gaps.
Cleaning the ash container
The ash container is located directly under the brazier - brazier holder. To clean it, open the ash door and remove the ash
and any combustion residuals using a suitable vacuum cleaner.
The door must be closed after cleaning. The ash container can be cleaned every 2-3 days depending on boiler use.
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.
