06. INSTALLATION
In compliance with the current regulations for installation, the pellet heating stove should be installed in a ventilated place with air that is sufficient to ensure correct
combustion and therefore good operation. The room must have a volume no less than 20 m³. In order to ensure good combustion (40 m³/h of air) there must be a
"combustion air intake" that reaches an external wall or a wall of an adjacent room with an external air intake (Ø 80 mm minimum diameter). The adjacent room
must not be a bedroom or bathroom, or contain any fire risks, such as storerooms, garages, combustible materials stores, etc. These air intakes must be made in
such a way as to avoid being blocked internally or externally, and should be covered with a grille, metal net or suitable protection, as long as the minimum diameter
is not reduced.
When it is operational, the pellet heating stove can cause a negative pressure in the room where it is installed. Therefore there should not be in the same room
other naked flame devices, with the exception only of type c stoves (watertight) unless they are fitted with their own air flow.
They must not be positioned close to curtains, armchairs, furniture or to other flammable materials.
They must not be installed in explosive or potentially explosive environments which may become explosive due to the presence of machinery, materials or dust
that can cause greenhouse gas emissions or which can easily ignite with sparks. Before starting to install the pellet heating stove, bear in mind that all the finishes
or any beams in flammable material must be positioned at a safe distance and outside the area of irradiation of the stove itself. Also bear in mind that to avoid
compromising correct operation of the appliance it is essential to create a recirculation of air inside its housing, which prevents overheating. This is possible by
respecting minimum distances and by creating ventilation holes.
06.1 HYDRAULIC CONNECTION
Remove the sides to better position the stove and to make the hydraulic connections.
They are fixed with quick-release clips.
The cooking stove is internally equipped with all the components for safety: automatic vent valve,
3 bar safety valve, expansion tank, stove safety thermostat, water pressure sensor.
It is however ADVISABLE to install an anti-condensation valve and a pressure gauge to read the
pressure. Remember to discharge the hydraulic system before switching on the appliance. It is advisable
to use hoses that connect the appliance to the hydraulic system, as in the case of
ordinary or extraordinary maintenance, movement is facilitated. It is also advisable to install a dirt
separator as
the electronic pump could capture the dirt of the system and become jammed.
See the INSTALLATION WARNINGS chapter for the distance between the hydraulic connections
and the size.
The system pressure must range from 0.5 to 2.5 bar. Upon exceeding of these thresholds
the WATER PRESSURE alarm will activate which will cause the product to shut down. The
recommended pressure is 1.5 bar
ELECTRICAL CONNECTION
The electrical connection must be performed by qualified personnel who install circuit breakers upstream of the appliance.
Special attention should be paid when the operation is a supplementary action and all equipment must operate as planned.
Avoid installations with electric cables that run close to fume pipes or hot components that are suitably insulated.
The voltage is 230 V while the frequency is 50 Hz.
The electrical system, at the connection point, must be have a ground connection as required by EEC Regulation 73/23 and EEC 93/98.
EXTERNAL THERMOSTAT
In this product it is possible to install an external thermostat. This operation may only be performed by authorised personnel. Use a 2-pole cable with everyday
double insulation. Connect the two poles to the connector of the TERM pin electronic board. Enabling the external thermostat by bringing to room temperature, T-
ON will be present when the thermostat prompts and T-OF when the thermostat is satisfied. If the thermostat is closed, the appliance works at the set heat output.
If the thermostat is activated, the appliance will work in the MODULATE state until it is switched off; if it is on STAND-BY, it is active.

07. METHOD OF USE
07.1 HYDRO MODE
In this mode, the cooking stove uses the heat generated from pellets to heat the home hydraulic system. The cooking stove should be positioned in this manner:
The lever of the Hydro/Oven adjustment must be completely extracted while the Oven adjustment must be turned anti-clockwise until it is completely positioned. In
this case, the heat output of the stove is regulated based on the temperature of the water in the stove or the ambient temperature or by an external thermostat.
11

07.2 OVEN MODE
In this mode the cooking stove uses the heat generated from pellets to heat the top plate and the oven. The cooking stove adjustments should be positioned in this
manner:
The lever of the Hydro/Oven adjustment must be completely inserted while the Oven adjustment must be turned clockwise until it is completely positioned. In this
case, the heat output of the stove is regulated according to the oven temperature.
ATTENTION: whenever the hydro/oven mode is changed, the board will emit a sound and a message will appear on the
display to remind you to reposition the upper adjustment.

FOR THE INSTALLER:
There are 3 standby modes:
Mode 1:
WITH RESPECT TO THE AMBIENT PROBE AND THE TEMPERATURE OF THE WATER.
Having set the water temperature, commence operation of the stove.
1- With the room set reached, the stove goes into stand-by
2- With the air set not reached, the stove is working.
Nearing Set Water, the stove goes into modulation and remains in modulation.
It goes into stand-by only when the Set Air is reached.
It comes back on when the stove is below the Set Air.
THE ENVIRONMENT PROBE HAS PRIORITY.
Mode 2:
WITH RESPECT ONLY TO THE WATER TEMPERATURE.
Having set the water temperature, commence operation of the stove.
Nearing the Set Water, the stove goes into modulation and when it is passed the Set goes into modulation and then stand-by.
Below Water Set the stove comes on again and resumes operation.
The stove in no way considers the temperature measured by the ambient probe of the same stove.
WATER TAKES PRIORITY
Mode 3:
WITH RESPECT TO THE THERMOSTAT AND TO THE TEMPERATURE OF THE WATER.
Having set the water temperature, commence operation of the stove.
1- With the thermostat open the stove goes into modulation then stand-by.
2- With the thermostat closed the stove is working.
Nearing Set Water, the stove goes into modulation and remains in modulation. It only goes into stand by mode when the thermostat opens the contact. It
turns on when the thermostat closes the contact.
The stove in no way considers the temperature measured by the ambient sensor of the same stove.
THE THERMOSTAT TAKES PRIORITY
Menu 06 – MODE BUZZER:
Set it to “OFF” to disable the buzzer.
Menu 07 – LOAD INITIAL:
This function is important if the stove is new or if the stove is off due to the absence of pellets in the hopper.
INITIAL IGNITION MUST BE PERFORMED BY AUTHORISED PERSONNEL ONLY, NOT BY THE PURCHASER.
CONTACT THE ASSISTANCE CENTRE TO ARRANGE FOR THE SPECIALIST TECHNICIAN TO BE SENT OUT.
Use this function to load pellets for a period of 90 seconds when the stove is switched off and cold. Start with button P1 and stop with button P4. The initial load is
enabled only if the product is in the Off status.

This function displays the current status of all the devices connected to the stove. A few examples are included in the following pages. The following will be
displayed: status time, including switching on and off, work, etc. pellet loading and output, the fume temperature and the fume rpm, the card temperature and the
water pressure.
Menu 09 – SETTINGS TECHNIC:
Menu for technicians, installers only.
Menu 10 – SELECET MODE (only visible in Oven mode):
In this menu it is possible to choose whether to heat the oven with pellets or with the electric heating element (in case you have purchased a cooking stove with
heating element and bulb). The cooking stove is equipped with a 1200 W electric heating element. Entering the menu it is possible to choose between THERMO-
S mode and STATIC mode:
THERMO-S mode: the cooking stove heats the oven using pellets. It is able to adjust its output according to the set temperature of the oven SET which in this
case varies from 80°C to 250°C. The actual stove output and status will be shown on the display
16

STATIC mode: the cooking stove is turned off. In this case the oven will be heated by the electric heating element inside it. The output of the heating element
varies according to the oven SET which in this case varies from 80°C to 230°C. It is also possible to set the oven SET to OFF in order to keep the heating element
off. The wording STATIC OVEN will appear on the display.
09. USER FUNCTIONS
Standard functioning of a control board properly installed on a forced air pellet stove is described below with reference to the functions available to users.
Stove ignition
Ensure that there are pellets in the hopper, that the burn pot is correctly positioned and free from any combustion residues and then close the door.
To turn on the stove, press button P4 for a few seconds. The display shows that the stove is on.
Start-up phase
The stove performs all the steps of the start-up phase according to the parameters concerning its levels and times. The display will show the wording START, as
there is no pellet loading but the exhaust blower is in operation.LOAD PELLET state will occur where the pellets are being loaded into the burn pot. Once the pellets
have started to burn and the fume temperature is increased, the display will show FLAME LIGHT, a transition phase between ignition and operating output.
Ignition fault
If the fume temperature has not reached the minimum permitted value after a predefined time, at a rate of 2°C/min, the cooking stove goes into alarm status.
If there are unburned pellets inside the burn pot, it is necessary to empty the burn put before switching on the stove again. Pellet waste and potential bursting inside
the combustion chamber will thus be avoided.
If the pellets have begun to burn but the alarm state persists, wait until all the pellets are burning and then switch on again.
Check that there are pellets inside the hopper.
Stove working in Hydro Mode
At the end of the start-up phase, if no problems occurred, the stove enters its normal working mode.
Changing set room temperature
Press button P2 to change the set room temperature. The display shows the current SET temperature value.
Changing set stove temperature
Press button P1 to change the set room temperature. The display shows the current SET temperature value. The stove temperature range varies from 50°C to
75°C.
External thermostat/chrono-thermostat use
If you want to use an external programmable thermostat, connect it to the TERM clamps (connector CN7 pin 7-8).
•External thermostat
•External chrono-thermostat
The stove external thermostat is enabled when the contact is closed with stove on.
Room temperature reaches the set value (SET temperature)
When the room temperature has reached its set value, heat output is automatically brought to its minimum value, (MODULAZIONE) status. The word MODULAT-
will appear on the display.
If the STAND-BY mode has been activated, the stove switches off with a delay equal to a predefined time and after reaching the temperature SET. Re-ignition
occurs after occurrence of the following condition: The environment decreases by 2°C with respect to that of SET.
The stove temperature reaches the set temperature (SET temperature)
The same situation is obtained when the stove temperature reaches the same level as that set. The modulation status is evident and, if enabled, STAND-BY status.
The stove is working in Oven Mode operation
Once the start-up phase has been successfully completed, the stove switches to work mode which represents normal operation.
All the caloric output of the pellets is transmitted to the cooking stove plate and to the oven.
Changing the oven temperature setting
To change the oven temperature, simply press the buttons P1 and P2. The display shows the current SET temperature value. If the stove is in THERMO-S mode,
the heat output will vary based on the temperature of the oven. If it is in STATIC mode, the heating element will vary its output according to the oven temperature.
When the oven mode is active, the stove will never go into STAND-BY.
17

CAUTION:
In THERMO-S mode it is possible that the cooking stove will need to dispose of the heat produced by the pellet also through the hydraulic system. In this case,
when the water temperature reaches a pre-set threshold, the SMALTIRE message will appear on the display. It will therefore be necessary to dispose of the water
heated by the pellet through a radiator or in any case from the hydraulic system.
Cleaning the burn pot
During normal operation in work mode, the "CLEANING FIRE-POT" mode is activated at set intervals.
Stove switch off
Hold down P4 button for approx. 2 seconds to switch off the stove. The Auger tube stops immediately and the exhaust blower reaches its maximum speed value.
The CLEANING FINAL phase is performed.
Stove switched off
The display will show the word OFF. The exhaust blower stops.
Stove re-ignition
It will not be possible to restart the stove until the fume temperature has fallen below a predetermined value and the 10-minute safety time has elapsed.
What happens if…:
The pellets do not ignite:
In the event of failed ignition, the NO LIGHTIN- alarm message is displayed.
