Operating area
For proper functioning and a good temperature distribution,
the stove shoul be positioned in a location where it is able
to take in the air necessary for combustion of the pellet
(about 40 m3/h must be available), as laid down in the
standard governing the installation and in accordance with
local national standards.
The volume of the room must not be less than 30 m3.
The air must come in through permanent openings made
in walls (in prossimity to the stove) which give onto the
outside, with a minimum cross-section area of 100 cm2.
These openings must be made in such a way that it is not
possible for then to be obstructed in any way. Alternatively,
the air can be taken from rooms adjacent to the one which
needs ventilating, as long as they are provided with an air
intake from the outside, and are not used as bedrooms or
bathrooms, and provided there is no fire risk such as there
is for example in garages, woodsheds, and storerooms,
with particular reference to what is laid down in current
It is not permissible to install the
thermostove in bedrooms, bathrooms,
or in a room where another heating
appliance is installed (fireplace, stove etc.) which
does not have its own independent air intake.
Locating the thermostove in a room with an
explosive atmosphere is prohibited.
The floor of the room where the thermostove is
to be installed must be strong enough to take its
weight. If walls are flammable, maintain a minimum
distance of 10 cm at the rear (A), of 40 cm at the
side (B) and 150 cm at the front.
If the room contains objects which are believed to
be particularly delicate, such as drapes, sofas and
other furniture, their distance from the thermostove
should be considerably increased.
40 cm
100 cm2
Connection to the external air intake
It is essential that at least as much air must be able to
flow into the room where the thermostove is installed as
is required for proper combustion in the appliance and for
the ventilation of the room.
This can be effected by means of permanent openings in
the walls of the room to be ventilated, which give onto the
outside, or by single or collective ventilation ducts.
For this purpose, on the external wall near the thermostove,
a hole must be made with a minimum free cross-section of
100 cm2. (equivalent to a round hole of 12 cm diameter or
a square hole 10x10 cm) protected by a grille on the inside
and the outside.
The air intake must also: communicante directly with the
room where the thermostove is installed be protected by
a grille, metal mesh or suitable guard, as long as this does
not reduce the area below the minimum.
Be positioned in such a way as to be impossible to
In the presence of wood floors, install a
floor protection surface in compliance
with the rules in force in the country
It is not compulsory to connect the air
intake directly with the stove (so that it
draws air directly from outside), but it is
essential at all events to ensure an airflow of 50
cubic metres per hour by the use of a hole of the
dimensions given. See standard UNI 10683.
Connection to the flue pipe
The flue pipe must have internal dimensions not larger
than 20x20 cm, or diameter 20 cm. In the event of larger
dimensions, or of the flue pipe being in poor condition ( for
example cracks, poor insulation, etc.), it is advisable to fit
a stainless steel pipe of suitable diameter inside the flue
pipe throughout its length, right up to the top.
Check with suitable instruments that there is a draught
between 6 Pa and 10 Pa. This type of connection ensures
the evacuation of the fumes even in the event of a
temporary power cut.
At the bottom of the flue pipe, provide an inspection cap
to allow periodic checking and cleaning, which must be
done annually. Make a gas-tight connection to the flue
pipe, using pipes and connectors as recommended by us.
You must ensure that a windproof cowl should be fitted
which complies with the standards in force
Connection to an external flue with insulated or
double-wall pipe
The only type of pipe which is permissible is insulated
(double-walled) stainless steel, smooth on the inside,
fixed to the wall. Flexible stainless steel pipe must not be
used. At the bottom of the flue pipe, provide an inspection
cap to allow periodic checking and cleaning, which must
be done annually. Make a gas-tight connection to the flue
pipe, using pipes and connectors as recommended by us.
You must ensure that a windproof cowl should be fitted
which complies with the standards in force.
Check with suitable instruments that there is a draught
between 6 Pa and 10 Pa.
Connection to the flue pipe
For proper functioning, the connecting pipe between the
stove and the chimney or flue duct must have a slope of
not less than 3% in the horizontal stretches, the length of
which must not exceed 2 metres and the vertical distance
between one tee connector and another (change of
direction) must not be less than 1,5 m.
Check with suitable instruments that there is a draught
between 6 Pa and 10 Pa. At the botton of the flue pipe,
provide an inspection cap to allow periodic checking and
cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes
and connectors as recommended by us. You must ensure
that a windproof cowl should be fitted which complies
with the standards in force.

Distance to objects
Avoid contact with combustible materials (example:
wooden beams) and in any case provide for their insulation
with flame retardant material. In case of pipe penetrations
through roofs or walls is recommended to use special
kits crossing, certificates, are available commercially. In
the event of a chimney fire, turn off the stove, disconnect
from the network and never open the door. Then call the
The thermostove should be inspected on all sides, so you
have to keep a distance of at least 40 cm at the back and
sides. It is also recommended to keep the pellets and all
flammable materials at a suitable distance
40 cm
The chimney cap
The chimney cap must respect the following requirements:
• It must have the equivalent diameter and internal form
of the flue.
• It must have a useful outlet diameter of not less than
double that of the flue.
• The chimney cap on the roof or that remains in contact
with the outside (for example, in case of open lofts or attics), must be covered with elements in brick or tile and
must, in any case, be well insulated.
• It must be constructed to prevent rain, snow, and extraneous bodies from entering the flue and so that the
discharge of the products of combustion is not inhibited
by wind from any quarter or strength (wind-proof chimney cap).
• The chimney cap must be positioned in such a way as
to guarantee the adequate dispersion and dilution of the
products of combustion and in any case, must be out of
the reflux zone. This zone has different dimensions and
forms according to the angle of inclination of the roof so
it is necessary to adopt minimum heights (Fig. 2).
• The chimney cap must be a wind-proof type and must
be above the ridge.
• Eventual structures or other obstacles that are higher
than the chimney cap must not be too close to the
chimney cap itself.

Preliminary checks
Before switching on the pellet stove, make sure that the
pellet hopper is full, the combustion chamber is clean, the
glass door is closed, the power supply plug is connected
and the switch on the back is set to “1.”
Starting the thermostove
Press button for a couple of seconds until the thermostove starts.
“FAN” will be displayed on the
upper display and “ACC” on the
lower one. During this phase the
unit will carry out a diagnosis
(around 20 seconds) on the fume
extraction system.
“LOAD WOOD ”, is the next phase,
which indicates pellets should
be fed. The glow plug will heat
up to light the fire.
When the fume temperature is
50º C (approx. 10 minutes), the
thermostove will confirm the
ignition: “FIRE” will be shown on
the upper display and “ON” on
the lower one.
After this phase, which lasts
around 5 minutes, the heating
power (es. “p06”) and the room
temperature (es. “25C”), will be
simultaneously shown on the
upper display, and the system
delivery water temperature will
be shown on the lower display.
If the flame does not start up correctly within 10 minutes,
the thermostove jams: you will read the words “ALAR” on
the upper display and the words “NO ACC ”: blinking on the
lower display.
Wait 10 minutes until the cooling phase is completed,
open the door, empty the brazier and start a new light-up.
In case of repeated ignition lock-outs, while pellets
are fed regularly, there may be a problem caused by a
failing electric glow plug. In this case, while you wait for a
technician, the pellet boiler stove can be manually started
by using solid fuel cubes (firelighters).
Manual starting procedure:
• open the door;
• take a solid fuel cube and place it inside the brazier
together with some pellets;
• light a match and set fire to the solid fuel inside the

the thermostove will start working regularly.
Do not unplug the power plug to turn off
the thermostove; wait until the automatic
shutdown cycle finishes: the continuous
operation of the fumes extraction fan is normal
and may indicate that the stove is still hot. In the
event of low temperatures, it might happen that
the stove starts the smokes fan and circulator for
some minutes in order to prevent ice formation
on the pipes of the system. in the event there is a
power drop, the main board will exhaust the smokes
residuals as soon as the power supply is back on.
In order to do that, the main board will increase
the speed and show the words “COOL FIRE ” on the
display. As soon as the cooling phase has been
completed, the stove will automatically start up
working as it was set before the power drop.
Room sensor
Internal room sensor
Position of the probe internal environment
Only when the laying is finished recommended to check
that the probe is lifted from its surroundings and away
from the structure of the hot thermostove, to prevent it
from detecting incorrect temperatures.
The room probe is located at the back of the thermostove.
When using the internal thermostat, you should always
set a slightly higher temperature a few degrees (eg 22 °
C, if you want to 20 °C environmental) because the probe
is affected, however, the influence of the hot thermostove
Example of operation:
If the room temperature detected by the sensor and
highlighted on the control panel is 15° C and the set
temperature is 20 ° C, the stove will follow a pre-established
ramp up to the 5 th power and to the achievement of the
target leads to the heater is minimum power. Once 20°
C is reached, it will go into standby mode et displays
the word “ECO-STOP”. When the room temperature drops
below the value set on the control panel (for example
18° C) and a sufficient shut down time has elapsed,
the thermostove will come back on automatically and
continue running until again reaching 20° C.
Regardless of the operation of the external thermostat,
the stove is equipped with an internal thermostat that
works in the following way:
Thermostove modulation turned on
The thermostove, when the set temperature is reached,
will modulate its output to the minimum, that is, until there
is again power demand. If despite the reduced power
operation, in the modulation mode, the water temperature
continues to rise to over 15° C of the set temperature and
remains so for an interval of at least 60 minutes, the stove
will turn off. Across the display will show “STOP-FIRE”.
The subsequent automatic restart will occur as soon as
the water temperature drops below 15° C above the set
water temperature.
External room sensor
Position of the probe external room sensor
The external thermostat is not included with the
thermostove and is borne by the user.
The thermostove can also be controlled in temperature
by a thermostat external environment. It is placed in a
median position with respect to the local installation and
ensure a better match between the heating temperature
required and that actually provided by the same.
Connect the two wires of the cable coming from the wall

If you enable this functionality the thermostove, when the
set temperature is reached, The thermostove will stabilize
at minimum power for a time T1 which can be from a
minimum of 1 minute, to a maximum of 30 minutes. If
by this time there is a further request of temperature, the
thermostove will automatically turn off and the display will
show the message “STOP-FIRE T ECO OFF”.
The thermostove will automatically turn on only if there
is a demand from the thermostat temperature. When the
temperature drops below the value set on the thermostat
(eg 18 ° C), the heater turns back on automatically until
again reaching 20° C.
All the operations of automatic reignition, and in the case of lowering
the ambient temperature of hot water

off using the power button, the stove does not
perform automatic re-ignition upon temperature
variation or if there is a demand for hot water. It is
recommended that, in the presence of the kit for
the production of domestic hot water, to disable
the ECO-STOP mode to shorten the response
time to the hot water demand.
Plumbing system connection
The connection of the stove to the
plumbing system must be made ONLY by
specialized personnel who are capable of
carrying out installation properly, in compliance
with current standars in the country of installation.
The manufacturer will not be held responsible for
damage to persons or things in the event of failed
operation if the aforementioned warning is not
complied with.
There are 2 different types of systems:
- Closed vessel system
- Open vessel system.
Closed vessel system
This product has been designed and built to work with
closed vessel systems. In general, the closed vessel
system has the following expansion as the expansion
vessel pre-loaded. In addition to the expansion device,
the closed vessel system must be provided in accordance
with current Italian UNI 10412-2 (2009) by:
• safety valve
• thermostat control of the circulator
• device alarm sounds
• temperature Indicator
• pressure indicator
• audio alarm
• automatic adjustment
• safety thermostat with manual reset
• circulation system
Open vessel system
The open vessel system is a more secure system that
does not require the addition of further securities. The
fireplace stoves, wood boilers and stoves necessarily
require use of an open vessel system. A plant run open
vessel, connected to a thermoproduct, may provide for
circulator mounted on the return, in this way the system
would work at lower temperatures to the advantage of a
longer life. While working under optimal conditions, the
pump mounted on the back can push the water through
the tube pan on safety and can make it back in the system
through the inlet pipe causing a phenomenon of oxygen
that is highly damaging to life of the boiler.
To prevent this phenomenon, it is possible to apply the
following measures:
• lower the speed of the pump so as to reduce the
• hold, if possible, the tray a little lower and raise the
maximum allowed the safety tube
• perform the separation between the safety pipe and the
discharge pipe, not at an angle of 90 ° but with a curved
Diagram connection kit without hot water
The pressure relief valve (C) must always be connected
to a water drain pipe. The tube must be capable of
withstanding high temperature and pressure.

The thermostove can also be equipped with a full
kit for the production of domestic hot water.
This kit comprises:
- a plate heat exchanger
- a three-way diverter valve
- water flow switch
- pipes and unions for connection
A plate heat
The kit is preassembled by the manufacturer’s task is to
heat the domestic water from the water line of the dwelling.
In the moment in which there is request for opening a hot
water tap, the flow switch commands the diverter valve to
convey the hot water contained inside of the thermostove
towards the plate heat exchanger.
In the case in which the heater is turned off and there is
demand for sanitary water, the heater after 30 seconds
from the request, it automatically starts the ignition
process to heat the water inside the boiler and then to
heat the sanitary water.
Directions for use
If the installation of the thermostove provides interaction
with another existing system complete with a heater
(gas boiler, gas boiler, oil boiler, etc..) consult qualified
personnel who can then answer the compliance of the
system, as envisaged by the law in force.
These are as helpful as the supply and return piping

Filling the thermostove funding of healt kit
Once all the water connections, proceed to check pressure
seal by filling the thermostove. During this operation, any
air in the system is released from the automatic vent

Flushing the system
In accordance with the UNI-CTI 8065 is strongly
recommended to wash the entire system before
connecting it in order to get rid of residues and
deposits. After flushing the system to protect it against
corrosion and deposits, it is recommended the use of
Upstream from the stove, always install shutters so as
to disconnect it from the plumbing system should it be
necessary to move it, or when it requires routine and/or
special maintenance. Connect the stove using hoses so
that the stove is not too strictly connected to the system,
and to allow slighht movement.
The filling pressure of the system when cold must be
1 bar.
During operation, if the system pressure drops (due to
evaporation of dissolved gases in the water) to values
lower than the minimum indicated above, the user must
use the filling tap to bring the pressure back up to its
normal pressure.
For proper operation of the stove when hot, the pressure
in the boiler must be 1,5 bar.
Water Characteristics
The characteristics of the water used to fill the system are
very important to prevent the build-up of mineral salts and
the formation of incrustations along the pipes, in the boiler
and in the heat exchangers.
Therefore, please get your plumber’s advice concering:
• Hardness of water circulating in the system, to prevent
problems of incrustation and limescale, especially in the
domestic water heat exchanger (>25° French).
• Installation of a water softener (if water hardness > 25°
• Filling the system with treated water (demineralised).
If you have very extensive system, with a large amount of
water, or which require frequent refilling, it is recommended
the installation of water softening system. It ‘should
be noted that the encrustations drastically reduce
performance because of their low thermal conductivity.

If the flame does not light up during the switching on or if
the smokes temperature does not reach a suitable value in
the foreseen time gap, the thermostove switches off and
you will read the words “Alar No Acc” on the display.
Press the key “On/Off” to reset the alarm. Wait until the
cooling phase is completed, clean the brazier and start a
new light-up.
Switching off while working
The thermostove suddenly switches off while working (for
example because it has run out of pellets in the tank or
because the motor reducer for pellets loading got broken).
The thermostove continues working until the pellets left
in the brazier ends. You will then read the words “Alar
No Fire” on the display and the stove switches off. Press
the key “On/Off” to reset the alarm. Wait until the cooling
phase is completed. Clean the brazier and start a new
These alarms remind you that the brazier must be
cleaned and installed correctly before switching on
the thermostove.
System pressure safety
The system pressure is checked electronically and needs
to be between 0,5 and 2,3 bar. If this is not the case, the
pellet boiler stove signalises an alarm and shows the
words “Alar Press” on the display.
Press” on the display. Check the system pressure keeping
the key
pressed for some seconds. You will read the
bar value on the display.
The safety valve keeps anyway the value under 2,5 bar
letting the exceeding water flow out automatically.
There is no power supply
In the event of a power drop longer than one minute, the
thermostove can exhaust some smoke in the room: this
causes no risks.
As soon as you have the power supply again, the
thermostove will have the words “Cool Fi re” on
the display. After completing the cooling phase, the
thermostove will start up again automatically according to
the previous settings.
Do not attempt to start the thermostove
before the required time or it may get
blocked. If this occurs, switch off the
switch on the back of the pellet boiler stove for 1
minute, set it on again and wait 10 minutes before
starting the thermostove again.
The power socket where the thermostove
is connected should be fitted with “earth
connection complying with regulations in
force.” The Manufacturer shall not be held responsible for damage to things or people resulting from
negligent installation.
Intervention in case of danger
In case of fire, disconnect the power supply, use a fire
extinguisher in accordance with, and if necessary, call the
fire department and then contact an authorised qualified
technical assistance
Maintenance and cleaning
All cleaning of all parts must be carried out with the stove completely cold and unplugged to
avoid burns and thermal shock. The stove does not need much maintenance if used with certified
quality pellet. The need for maintenance varies depending on the conditions of use (switching on

Daily control
The thermostove requires a simple and thorough cleaning
in order to ensure a more efficient performance and
smooth operation.
While cleaning the inside of the thermostove, to prevent
the escape of ashes, you can start the fan flue exhaust.
To enable this feature, you must press the button
then .
The display shows “PUL STUF” (cleaning thermostove).
To stop the fan, simply press and hold the button or wait
for completion of a cleaning cycle (255 seconds).
Clean the grate using the appropriate tool from the ash
and any incrustation which could obstruct the passage
of air. In the case of depletion of pellets in the tank may
accumulate unburned pellets in the burn pot.
Always empty the residuals from the grate before each
start. Remember that only a brazier located and clean
properly can ensure ignition and optimal operation of your
thermostove. When positioning the crucible, carefully
check that the ends of the pads completely adhere to
their home and that the hole with pipe dedicated to the
passage of the resistance.
There should be no residual combustion in the contact
zone between the edges of the crucible and the support
surface on the door crucible.
The decreased or absent cleaning can
cause misfire and cause damage to the
thermostove and the environment (possible emissions of soot and unburned). Do not pour
the pellets may be present in the brazier to misfire.
Cleaning exchanger - stove off
Fouling act as insulation and the thicker they are, the
lower the heat that is transmitted to the water and to the
structure generally. Therefore very important to perform
the cleaning of the tube bundle, said exchanger also, to
prevent the fouling of the same and prevent clogging and
jamming of the cleaning device. Pull and push quickly for
5-6 times the lever so that the springs can remove the
soot deposited on the pipes.
Cleaning of painted pats
Do not clean the painted parts with wet rags when the
unit is in operation or hot to prevent thermal shock to the
paint which may cause it to detach. Do not use abrasive or
aggressive products or materials. Clean with damp cotton
or paper towels. The silicon paints used by manufacturer
possess technical characteristics that make them resistent
to very high temperatures. There is however a physical
limit (380° - 400°) beyond which the paint begins to fade or
(over 450°) to vitrify; it may then flake and detach from the
steel surface. If this happens, it means that temperatures
have been reached that are far above those at which the
unit should operate properly.
Do not use abrasive materials or harsh.
Clean with damp cotton or paper towels.
Check every 7 days
Check every 2/3 days
Cleaning the ash collection compartment.
Clean and empty the ash tray being careful with hot ash.
The ash must be completely cold for a vacuum cleaner to
be used to remove it. Only if the ash is completely cold,
you can also use a canister vacuum cleaner suitable for
picking up particles of a certain size.
Clean bottom ash from the fallen debris during operation.
You can access the ash pan by loosening the two wing
nuts that hold the drawer inspection. Remove the tray,
empty and clean the wall and only the corners with a
suction device or with dedicated tooling. Then mount the
drawer and tighten the two knobs being careful to restore
the tightness, very important during operation.
Cleaning ash and combustion chamber including the
spark plug lead
Cleaning the glass
For cleaning the ceramic glass, the use of a dry brush
is recommended, or if it is very dirty, the special spray
detergent, applying a small quantity then cleaning with a
Do not use abrasive products and do not
spray the cleaning product on the glass of
the painted parts or on the gaskets of the
fire door (ceramic fibre cord).
Cleaning of stainless steel and satin-finish surfaces
Normally these surfaces do not need to be treated, but
if they do, avoid cleaning them with abrasive materials.
For surfaces in stainless and satin brushed steel we
recommend cleaning with a paper towel or a clean dry
cloth moistened with a detergent based on non-ionic
surfactants (<5%) A spray glass cleaner may be used.
Avoid contact with skin cleanser and eyes.
In case this happens, sprinkle with plenty
of water and contact the nearest medial
Check every 60/90 days
Cleaning the interior baffle / smoke fan compartment.
Inside the compartment where there is the ash tray,
there is a second cover, fixed by the cockerels, which
gives access to the compartment at the base of the duct
dedicated to the flue and the wall of the fume extractor
fan. Use a suction device for thorough cleaning of the
cabinet. Check the integrity of the seal in ceramic fiber.
Cleaning battifiamma
The thermostove is provided with two elements in vermiculite:
the bottom of the combustion chamber and the battifiamma.
Check every year
Compartment ventilation flue gas cleaning
Remove the fixing screws and remove the smoke fan for
cleaning of the same. Perform the task with the greatest
care not to bend the fan blades.
Vermiculite is a mineral from a variety of uses in industry
and construction for its insulating properties, thermal
and acoustic properties. In this case, the vermiculite is
used to avoid unnecessary heat dispersions. Because
of its fragility, it is recommended to handle with extreme
care battifiamma during the cleaning of the combustion
chamber and clean it only with a soft, dry cloth.
Clean flue
Clean the flue system especially near the fittings to “T”,
curves and any horizontal sections. Is necessary to check
and remove any deposit of ash and soot before the same
clogging the passage of smoke.
Cleaning the exchanger
Lift the upper door that covers the tube by unscrewing the
screws. Pull out the 16 soft brush and wipe with a clean
16 exchanger tubes.
Shutting the thermostove down
In the period when the thermostove is out of use it
must be disconnected from the electricity mains. For
greater safety, especially if there are children around, we
recommend removing the power cable from the rear of the
Perform cleaning after removing the springs inserted
in each pipe. The operation is simple by removing the
springs from the horizontal pin to which they are attached.
To do this, the horizontal pin can be pulled through a hole
in the wall of the thermostove body.
Before placing the thermostove in storage, you should
remove all pellets from the hopper with a vacuum cleaner
with a long extension. If the fuel is left in the hopper, it may
get damp, stick together, and be difficult to light at the
beginning of the next season.
If pressing the main switch (located on the back of the
stove) does not make the control panel display light up, it
could mean that the service fuse needs replacing.
On the rear of the stove there is a fuse holding
compartment which is located underneath the supply
socket. With a screwdriver open the cover of the fuse
holding compartment, and replace the fuse if necessary
(3,15 AT delayed type). Plug the unit back in and press the
main switch.
Now the upper section to the heat exchanger is free
from any encumbrance so as to allow a perfect cleaning.
Once a year is also recommended to clean the upper
compartment of the exchanger. To make a proper cleaning
is recommended to suck the ash, remove all horizontal
joints with a screwdriver, then again suck the ash.
We recommend that an annual maintenance service
is carried out, preferably under a programmed service
contract. The essential part of this service is a visual and
functional check on the following components:
• reduction motor
• smoke expulsion fan
• smoke sensor
• heat-exchanger fan
• ignition sparkplug
• resettable pellet thermostat
• room temperature sensor
• pressostat
• motherboard
• fuse protecting panel - motherboard
The transaction can be completed with a screwdriver by
removing the wall of the thermostove and removing all
horizontal joints.
These operations must be performed by a
qualified technician, or the user who will
take responsibility in the event of damage
during maintenance.
Perform this maintenance heater cold and in the
absence of electricity. If such maintenance is
performed by an authorized service center is the
responsibility of the customer.
Surface cleaning
Following the cleaning of the upper compartment of
the exchange section, store the upper closure cover.
This cover must be closed, as well as with normal screws,
with webbing in ceramic fiber rope to ensure the watertight
closure of the thermostove.
This general cleaning should be carried out at the end
of the season in order to facilitate the general removal
of all residues of combustion, without waiting too long,
because with time and humidity these residues can
become compacted.
Check the seal of the ceramic fiber gaskets on the door of
the thermostove.
Then clean the flue system especially near the fittings to
“T” and any horizontal sections.
For your safety, the frequency of cleaning
the smoke discharge system must be
determined on the basis of how the
thermostove is used.
In case of failure or inadequate cleaning of the heater
may have function problems such as:
• poor combustion
• blackening of the glass
• clogging of grate with accumulation of ash and pellets
• ash deposit and excessive deposits on the heat exchanger resulting in poor performance.
The check of electromechanical components must be
performed only by qualified personnel with technical
knowledge of electricity and combustion.
The thermostove is a product by heating, presents the
external surfaces particularly hot.
For this reason, we recommend extreme caution when
operating in particular:
• Do not touch the thermostove body and the various
components, do not approach the door, it could cause burns;
• Do not touch the exhaust fumes;
• Do not perform any type of cleaning;
• Do not dump the ashes;
• Do not open the ash tray;
• Be careful that children do not come close.
All cleaning of all parts must be carried out with the stove
completely cold and the plug disconnected.
To clean the surfaces, use a rag dampened with water or
with water and a neutral detergent.
The use of aggressive detergents or
thinners can damage the surfaces of the
thermostove. Before using any detergent it
is advisable to try it on a small section out of sight
or contact the Authorized Assistance Centre for
information regarding the product.
Warnings for cleaning
All cleaning of all parts must be carried out with the stove
completely cold and the plug disconnected.
Before effecting any maintenance operation or cleaning
on the stove, take the following precautions:
• be sure that all parts of the stove are cold
• be sure that the ashes are completely cold;
• be sure that the general switch is in the “OFF” position;
• be sure that the plug is pulled out of the socket to avoid
accidental contact;
• Once the maintenance phase is completed check that
everything is in order as per before the intervention (the
brazier is placed correctly).
Any kind of tampering or unauthorized substitution of
non-original of the thermostove can be hazardous to the
safety of the operator and relieves the manufacturer from
any civil or criminal liability. Use only original spare parts.
Replace a worn before failure promotes the prevention of
injuries resulting from accidents caused by the sudden
failure of the components.
After 1300 hours of operation of the
heater will appear on the lower display
the word “SERV”, please contact your
Authorized Service Center for cleaning and
routine maintenance.
Follow carefully the following cleaning
instructions. Failure to follow these
instructions could create problems with
the operation of the thermostove.
Problems and solutions
All repairs must be carried out exclusively by a specialised technician, with the stove completely
cold and the electric plug pulled out. Is prohibited from any unauthorized modification to the
device and the replacement of parts with other non-original. The operations marked in bold type
must be carried out by specialised personnel.
