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
baffles and flueways. To do this, remove the cover and the top front panel of the stove. Remove the cast iron
exchanger by undoing the fixing screws then clean the baffles and the chamber.
Also make sure to clean the fume extractor located under the chamber, accessed by removing the inspection port
located on the front lower part of chamber.
Every 3-4 months clean the inside walls (insulating-refractory) of the combustion chamber using suitable
equipment (brushes) and replace them 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.
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 (ceramic models)
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 depending on stove use and the
type of installation.
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.
For any maintenance or end of season cleaning, COLA recommends contacting an authorised service
centre, which will also check the wear on the stove's internal components.
