8.3.2. CLEANING THE ASH CONTAINER

Clean the ash container as follows:
Step Action
1 Open the ash door.
2 Remove the ash and any combustion residuals using a suitable vacuum cleaner.
3 The door must be closed after cleaning.
The ash container can be cleaned every 2-3 days depending on boiler use.

8.3.3. 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.
Clean the combustion chamber as follows:
Step Action
Remove the boiler top cover, the heating chamber cover and the bottom inspection
1
door, undoing the respective fixing screws.
2 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.

8.3.4. CLEANING THE AIR FLOW METER

There is an air flow meter (it measures the flow of combustion air) inside the inlet pipe that
requires periodical internal cleaning every 3-4 months, using suitable equipment (blowing
compressed air or suitable brushes).

8.3.5. 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.
