Boiler body maintenance
Danger!
Before performing any maintenance on the
boiler, make sure the boiler and its compo-
nents have cooled down.
Warnings
- Never drain water from the system, even partially, unless
absolutely necessary.
-
Periodically check the proper operation and integrity of the
flue gas exhaust pipe and/or device.
-
If work or maintenance is performed on the structures near
the flue gas pipes and/or flue gas exhaust devices and their
accessories, switch the appliance off and, when the work is
over, check their efficiency.
-
Do not clean the boiler and/or its parts with easily flammable
substances (e.g. petrol, alcohol, etc.).
- Do not leave containers with flammable substances in the
room where the boiler is installed.
-
Do not clean the boiler room while the boiler is running.
-
At the end of each heating period, inspect the boiler to keep
the system in perfect efficiency.
Thorough maintenance always enhances energy saving and
safety.
IMPORTANT
Clean with brushes and a vacuum cleaner; if you
use any rags, make sure you collect all these.
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 fire 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 flame dies down, before loading wood.
Every week
- Remove carefully all the residues of combustion accumulated
in the firewood 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 in-
structions 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 in the manner described in par. 3.15.4
and its perfect tightness when the door is closed.
Every year
