5.5.2 Air adjustment issues
1) If there is too much primary air,
there will be a large amount ash
and small pieces of coal coming
down. If the flame is too fast, dry,
has a cold colour and produces
noise. The boiler uses up lots of
wood.
2) If there is not enough primary air,
the flame will move slowly, flicker, be
easily influenced by gusts of wind
and the draught of the chimney, it
will be very small, it will not be able
to touch the lower cradle, thereby
generating little ash.
3) If there is too much secondary air,
the flame will be small, tending
towards a bluish colour and appear
very clear.
4) If there is not enough secondary air,
the flame will be large, it will touch
the lower cradle and will fill up the
entir e lower chamber. Mor e
importantly, it will be red and not
look clear at all.

WARNINGS

CORROSION OF THE FLUE GAS
CIRCUIT
Flue gases are full of water vapour due
to the combustion process and the
use of fuel full of water. If they come in
contact with relatively cold surfaces
(wit h a minimum t emperatur e of
about 60-70°C), the water vapour
condenses and by combining with
other combustion products it results
in corrosion of metal parts.
Check f or any signs of f lue gas
condensation on a dail y basis
(blackish liquid on the floor behind
the boiler).
In this case you need to use a drier
kind of wood. Check t he f lue gas
temperature in reduced mode and
increase the operating temperature.
To check the room temperature it is
therefore necessary to install a mixer
val ve. Cor r osion due t o f lue gas
condensation is not covered by the
warranty, as it is due to the wood's
moisture content and the boiler's
management.
WARNINGS DURING USE
Whenever the air is adjusted, wait 5-
10 minutes before going ahead with
the next adjustment. Once you have
established the optimal adjustment, at
the end of the day check the furnace
surfaces – these must be white.
There must only be a few unburnt
embers in the accumulated ash. If
there is too much primary air, there
will be embers and small pieces of coal
in the ash, the flame will move quickly,
will be dry, have a cold colour and
produce noise and the output will be
too high (5.5). If there is not enough
primary air, there will be a small flame
moving slowly and it will move a little
amount of ash and the output will be
too low. If the flame is dark orange,
there is not enough secondary air and
the surfaces of the furnace will not be
white. If the flame is small and blue,
there is t oo much secondar y air.
Slowly open the top loading door. If
despite this warning, there are some
puffs of air, use slightly damp large
pieces of wood. Make sure the boiler
does not stop for a long period of time
(reduce the primary air - 5.5) and
that any foreign bodies (nails, metal
parts) are not obstructing the hole of
the refractory burner.

MAINTENANCE

Caution! Before conducting any work
on the boiler, make sure the boiler
itself and its components have
cooled down.
Warnings! Never bleed out water
from the system, not even partially,
unless you need to do so for absolutely
imperative reasons.
Periodically check the conduit and/or
flue gas discharge device are intact
and in good working order. Do not
clean the boiler and/or its parts with
highly flammable substances (e.g.
petrol, alcohol, etc.). Do not leave
containers with flammable substances
in the room where the boiler has been
installed. Do not clean the heating
system when the boiler is in operation.
IMPORTANT: Use swabs and
aspirators to clean the equipment. If
you use any cloths, make sure you
don't leave any of them inside the
equipment. Keep screws and nuts
lubricated and protect them with
grease.
5.7. 1 Routine cleaning and maintenance
of the boiler (fig. 11)
ON A DAILY BASIS
- Remove the deflector (A) from the
drying and gasification chamber.
- Remove the layer of embers so that
the ash accumulated in the wood
storage area goes down through the
refract or y burner slot. This will
pr event t he slo t fr om being
obstructed, which would affect the
boiler's operation.
- Put back the deflector (A) by placing
it at the centre of the slot.
ON A WEEKLY BASIS
- Accurately remove from all surfaces
any combus tion
accumulated in the wood storage
area.
- Use a swab to clean the flue gas
ducts of the combustion chamber.
- Remove the ash from the ash tray
(B).
- Make sure the refractory burner slot
is not obstructed: if so, clear it by
using a fire poker.
- If the malfunction persists even after
t he equipment is cleaned as
described above, this may due to a
poor distribution of the secondary
air. In this case:
1) check the notches of the air
supply outlets (pos. P - pos. S) based
on the indications reported in the
paragraph "Adjusting primary and
secondary combustion air" (5.5).
2) make sure the secondar y air
supply holes of the burner (C) are not
obstructed: in this case, pass a long
soft brush through each duct.
- Make sure the refractory burner and
the deflector (A) are positioned
correctly in place.
Caution! The refractory burner and
the deflector are subject to wear: we
therefore recommend checking them
every year to prevent an anomalous
operation of the boiler.
ON A MONTHLY BASIS
Check the operation of the bypass
device (D). The bypass is a direct
passage between the wood storage
area and the chimney. When the
loading door is opened and the fan
s t ar ts aut omatically, it allows t o
collect the flue gases accumulated in
the wood storage area and send them
to the chimney. The bypass device
basically allows the flue gases to be
dischar ged t owar ds the chimney
without coming out from the top door
dur ing switch-on and
operations.
