5.2 Cleaning the ash container
The ash container is located directly under the brazier - brazier holder. To clean it, open the fire door and remove the
ash and any combustion residuals using a suitable vacuum cleaner.
Close the door after cleaning. The ash container can be cleaned every 2-3 days depending on stove use.
5.3 Cleaning the glass
The glass can be cleaned using a damp cloth and specific non-abrasive detergents.
Special slots between the glass, glass stops and fire door at the top and bottom allow air to circulate on the inside
surface of the glass. These slots must be kept clean of any deposits of ash and dust. Therefore periodically clean all
around the glass, on the inside and outside of the door.
5.4 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 stove top cover, the heating
chamber cover and the bottom inspection door, undoing the relevant fixing screws, then clean the turbulators and
internal fume pipes. Also, make sure to clean the fume extractor located under the bottom fume manifold accessed
through the inspection door opening.
Every 3-4 months clean the inside walls (insulating-refractory) of the combustion chamber using suitable equipment
(brushes) and replace the vermiculite wall if necessary.
Every 1800 hours of operation or 2000 Kg pellet, by means of a message 'SERVICE DUE', the stove 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.
5.5 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).
5.6 Cleaning the ceramic surfaces
The ceramic tiles are handicraft products and therefore may have minor surface imperfections such as tiny spots or
slight colour differences. It is advisable to use a soft dry cloth to clean the ceramic surfaces; the use of detergents
could highlight any flaws.
5.7 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 stove to the flue.
It is advisable to also clean the flue every year, to ensure correct and safe evacuation of fumes.
5.8 Cleaning the exchangers with turbulator-shaker device
The fume ducts inside the heating chamber must be cleaned
at least once a day by operating the two knobs repeatedly with
an upward and downward movement.
Carry out this operation with the stove off and cold.

shaker device in heating stove operation
