Pump breakdown:
If the circulator stops, the system goes into alarm and
stops (Er01, Er04).
Ignition failed:
The system has 1 ignition attempt, if it is not successful
the boiler goes into a safe state then in BLOCK (Er12). Before each igni-
tion, the brazier self cleans, in case of self
-
cleaning failure the system will
go into error Er25.
Electrical protection:
The system is protected with a 4 A fuse that is
located on the back of the stove. To replace it, extract the tray next to the
switch only after disconnecting the power cable from the power supply,
replace the broken fuse and reinsert the tray, if the new fuse immediately
breaks, contact a technician.
Exhaust fume safety:
If there are any anomalies with the smoke expul-
sion from the system, an alarm will go off and the system will block (Er02).
Pellet safety:
If the temperature inside the pellet tank exceeds the safety
level, the system blocks (Er01). The reinstatement is automatic,
Water temperature safety:
In case the water temperature in the boiler
exceeds the safety level, the system goes into block (Er01). The reinstate-
ment is manual and must be carried out by a qualified technician by pres-
sing the reset button behind the boiler.
Water pressure safety:
The pressure of the system is controlled by an
electronic pressure transducer and must be in between 0.2 bar (200 mbar)
and 2,8 bar (2800 mbar), se non sono rispettate le condizioni, il sistema va
in blocco (Er09 o Er10), if these conditions are not complied with the sy-
stem goes into block (Er09 or Er10). If the system goes over 3 bar, an
automatic safety valve opens and releases the excessive pressure. To
regulate the pressure within the function range, adjust the discharge valve
behind the boiler or on the radiator.
Power failure:
If there is a short power failure in the power supply, the
system will go into BLOCK (Er15). If the lack of electricity is not brief, the
boiler could release a small quantity of smoke in the room, if the air intake
has not been correctly connected to the outside.
This is caused by the
scarce draw of the chimney flue and does not represent any risk for
one
’
s safety.
When the power comes back, the system switches itself off.
Warning: In the case the chimney catches fire, call the fire brigade.
MINIMUM SAFETY DISTANCES
Keep fuels and flammable substances at an adequate distance from the
stove. For minimum distances from flammable materials, one can refer to
the products identification plate located on the back of the stove.
Caution: Some models could have minimum safety distances diffe-
rent from dimensions shown below, therefore it is strongly recom-
mended checking always the idenditication plate located on the back
of the stove to make sure the values of minimum safety distances.
Connecting to a system with zone valves
Leave at least one zone always open. We recommend installing an anti
-
condensation valve at 55 °C (mandatory in the case of direct connection
to the system).
WARNING: the boiler must be installed on a properly sized system
to dispose of the power generated by the appliance. For the sizing
of the system it is recommended to rely on a thermo technician.
To dissipate excess heat, the boiler must be connected to at least two
radiators. The system drain valve and the safety valve are on the back of
the boiler, they must both be connected to a drain well according to the
regulations in force.
Hot water production kit (optional)
On the boiler it is possible to install a kit on board of the
appliance for the production of hot water. This optional
feature provides unmatched comfort because everything
is completely automatic and controlled by the control unit.
Note:
The kit must be connected to the hydraulic system
in accordance with its input and output indications, the maximum admis-
sible pressure is 2 bars (this operation must be carried out by a qualified
technician).

term non
-
use conditions
If the hydro stove has not been used for a long period of time, it is rec-
ommended to contact a qualified technician to carry out the following
operations:
-
Apply adequate antifreeze according to the area where it is located
-
Place the switch in the
1
position
-
Close all the valves of the heating and domestic water system
Operating Conditions
The boiler has been designed to be used in ordinary environments, whe-
re there is no danger of fire or explosion. The disposal of combustion
waste must be carried out in accordance with the applicable legal provi-
sions.
When using the boiler, the settings of the safety devices or the fixed
guards can not be changed. The control devices must be regulated by
qualified technicians.
Maintenance of the boiler must be carried out by specialized companies
in the maintenance of heating appliances, which will subject it to all the
checks required by current regulations.
Use wood pellets with a diameter of 6mm, average
length of 30mm, with humidity characteristics in com-
pliance with the EN PLUS
-
UNI EN 14961
-
2 standard,
class A1. Store the fuel in a cool, dry place away from
heat sources.
Caution: The boiler modified or equipped with special
applications must undergo a new conformity check. The incorrect
connection of the boiler to the chimney and failure to comply with
the provisions regarding the construction of the ventilation ope-
nings can cause serious dangerous situations.
Residual risks
Some parts, for example the smoke outlet, during operation may be very
hot to the touch and cause burns. The electrical parts can cause serious
damage, do not touch these parts without having disconnected the
mains cable from the mains.
SAFETY DEVICES
Breakage of the exhaust fan:
If for any reason the fan breaks, a safety
measure intervenes and blocks the pellet flow (Er02), an alarm goes off
and stops the stove
’
s function.
Breakage of the auger motor:
If the auger motor stops feeding pellet,
the system still continues to function on minimum levels then an alarm
goes off and the stove blocks (Er12, Er03).
Note:
The stove can be installed close to a not flammable material wall,
as long as electronic devices and electrical connections will be accessi-
ble and there will be enough space for maintenance
