Cleaning The Ash Container; Cleaning The Fume Extractor And Combustion Chamber; Cleaning The Air Flow Meter; Cleaning The Flue - Flue Connection - Cola DOMUSFIRE C17 Manuel D'installation, D'utilisation Et D'entretien

5.2 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.

5.3 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 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.

5.4 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).

5.5 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.

5.6 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.
- Do this with the boiler off and cold.
- At the end of the operation make sure the turbulators are in the rest position on the lowest level.
RH - LH control knobs of the turbulator-
shaker device in boiler operation low
position.
