Cleaning the fume extractor and combustion chamber
5.4
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, and the heating
chamber cover, undoing the fixing screws, then clean the turbulators and internal fume pipes.
Also make sure to clean the fume extractor located under the chamber, accessed by removing the ash pan.
Every 3-4 months clean the inside walls of the combustion chamber using suitable equipment (brushes) and
replace the vermiculite wall if necessary.
Every 1800 hours of operation, 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.
Cleaning the air flow meter
5.5
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 ceramic surfaces (ceramic models)
5.6
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.
Cleaning the flue - flue connection
5.7
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.
Cleaning the exchangers with turbulator-shaker device
5.8
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.
