6.11 - MAINTENANCE 

Danger!
Before performing any maintenance, 
make sure the boiler and its components 
have cooled down. 

 

Warnings 

Never drain water from the system, even partially, unless 
absolutely necessary.

Periodically check the proper operation and integrity of 
the fl ue gas exhaust pipe and/or device.

Do not clean the boiler and/or its parts with easily 
fl ammable substances (e.g. petrol, alcohol, etc.).
Do not leave fl ammable substances in the room where 
the boiler is installed.

Do not clean the boiler room while the boiler is running.

IMPORTANT

Use brushes and a vacuum cleaner to 
clean the heat stove; if rags are used, 
make sure they are all recovered.
Keep screws and nuts oiled and protect 
them with grease.

CLEANING AND ROUTINE MAINTENANCE OF 

THE WOOD-FUELLED BOILER

Every day

-  Remove the ashes from the lower cradle.
-  Shake down, with the scraper supplied with the boiler, 

the embers so that the ashes, accumulated in the fi re 
bed will fall down through the slots in the grate. This 
operation will help to avoid the grate from becoming 
obstructed and the subsequent bad operation of the 
boiler. This operation has to be done when the fl ame 
dies down, before loading wood.

Every week

-  Remove carefully all the residues of combustion 

accumulated in the fi rewood storage compartment.

-  Use the supplied brush to clean the triangular ducts 

in the furnace.

-  Remove the ashes contained in the smoke chamber 

from the side doors using a scraper.

-  Make sure that the slots in the grate are not 

obstructed: if they are, clear them up using the poker.

-  If the boiler continues to operate badly, even after 

having cleaned it as described above, the cause can 
be attributed to bad distribution of the secondary air.

In this case: 
1) check the adjustment of the air setting, according to 

the instructions given in the paragraph “Combustion 
air adjustment”.

2) make sure that the two secondary air supply holes 

that come through the grate are not obstructed: if 
they are, use a 

soft brush

 to clean out each duct.

Every month 

Check by-pass operation.
When the loading door is open the by-pass allows 
the fan to start up automatically, extracting the fl ue 
accumulated in the wood storage compartment, and 
sending it to the chimney.
The bypass, in conclusion, allows the smoke to be 
discharged to the chimney without escaping from the 
loading door when loading the wood or during lighting.

UNSCHEDULED MAINTENANCE OF WOOD-FUELLED 
BOILER

At the end of each heating season, perform a general 
cleaning of the boiler by removing all the ashes from 
the fi rewood storage compartment. 
During summer, keep the boiler doors closed.

Cleaning the fan

ATTENTION: 
This operation is reserved for qualifi ed 
personnel as incorrect maintenance 
could jeopardise operation of the boiler.
