10. MAINTENANCE AND CLEANING
Before performing any maintenance always disconnect power to the boiler and wait for the appliance to
reach room temperature.
Never drain the water from the system unless absolutely unavoidable.
Periodically check operation of the flue exhaust device and/or pipe.
Do not use flammable substances (petrol, alcohol, solvents, etc.) to clean the boiler.
Do not leave containers of flammable materials in the room where the boiler is installed!
Careful maintenance ensures cost savings and safety.
10.1. Weekly cleaning
Remove any combustion residues from all parts of the top furnace (top door).
Using the special triangular brush supplied, clean the triangular passages in the bottom heat exchange
area (bottom door).
Remove the ash from the rear smokebox through the side doors.
Open the top door, remove the stainless steel grid plate (4) and use a steel brush to remove
combustion residues.
WARNING: the presence of combustion residues on the grid plate (4) after 8-20 hours of operation indicates
poor quality pellets have been used, containing a large amount of soil or bark (resins, etc.) or other non-
combustible material.
These types of residue cause considerable ignition and combustion problems if not frequently removed from
the grid plate (4), therefore it’s strongly recommended to use good quality and certified pellets.
Vacuum up any ash residues from the draught tube.
Clean the photocell glass (1).
Clean the inspection window (7).
10.2. Monthly maintenance
Clean any deposits from the fan blades. Normally compressed air or a light brush ensure perfect
cleaning. For more stubborn deposits, always proceed delicately to avoid unbalancing the fan and
making it noisier and less efficient.
Lubricate the motor’s head bearing.
Periodically check the condition of chimney and the draught.
Clean the flue gas probe.
A Make sure the primary air duct is not blocked by combustion residues or ash. Unscrew the screws
that adjust air flow (6), open the duct and vacuum up the ash.
