4 STOVE USE
4.1 Introduction
The pellet stove has the advantage of combining heat from a wood flame with the convenience of automatic
management of temperature and the possibility of weekly programming of lighting and shutdown.
For safe and reliable use, observe the following:
▪
when lighting the stove the first time, unpleasant odours may be created, therefore ensure good ventilation
of the room, especially during the first period of operation;
▪
the hopper must only be filled with pellets, without allowing the bag to come into contact with the hot
surfaces of the stove;
▪
do not put any type of fuel other than recommended wood pellets in the hopper;
▪
the unit must not be used as a waste incinerator;
▪
the stove must work only with the fire door always closed;
▪
the fire door seals should be checked periodically to ensure air tightness;
▪
to ensure efficient and correct operation, it is necessary to clean the brazier whenever pellets are loaded;
▪
when lighting the stove for the first time, make sure to allow it to get hot gradually without overheating;
▪
during lighting, operation and shutdown, the stove may creak a little due to the heat expansion.
4.2 Control panel
The control of the stove occurs through the use of a control panel provided with four buttons and an LCD display.
The panel allows activation and deactivation, adjustment during operation and the setting of management programs
and maintenance (ref. fig.4.2).
4.3 Lighting
Before lighting of the stove, check the following points:
−
make sure to have read and understood the instructions in the manual;
−
the hopper must be filled with pellets;
−
the combustion chamber must be clean;
−
the brazier must be completely free, clean of any combustion residuals and properly positioned in the
brazier holder;
−
check the hermetic closure of the fire door and ash drawer;
- At first lighting, remove from the stove firebox and glass any components which could burn
(instructions/label).
- Any lightings done after long idle periods require complete cleaning of the combustion chamber and the
removal of any pellets left in the hopper, in being damp fuel no longer suitable for combustion.
To light the stove, press button P4 on the panel for a few seconds. The message START will appear on the LCD
display. This phase is automatic and is managed completely by the electronic control, without any possibility to
intervene on the parameters.
The stove carries out the startup phases in sequence according to the procedure defined by the parameters,
reaching the work condition. After a certain time, if the fume temperature has not reached the minimum permissible
value, the stove goes in alarm status.
- Do not use flammable liquids to light the unit.
- In case of persistent failed lighting, contact the Service Centre.
4.4 Work
After the startup phase, the stove goes to WORK mode, which is normal operation. The heating power can be
adjusted by pressing button P2 and then buttons P1 and P2 from the maximum value of 5 to a minimum value of 1.
The stove automatically adjusts the ventilation of hot air according to the set power.
In addition to the power, also the room temperature can be adjusted. Press button P1 and with buttons P1 and P2
make the desired setting, from a maximum value of 40 °C to a minimum value of 7 °C.
- Make sure to check the pellet level in the hopper so that the flame does not go out due to lack of fuel.
- Make sure the unit is off when loading pellets.
- The pellet hopper cover must always remain closed, to be opened only during fuel loading.
- The bags of pellets must be kept at least 1.5 m away from the stove.
When the SET temperature is reached, the corresponding symbol lights up on the display.
If STANDBY mode is activated, the stove shuts down after a delay of several minutes. Restart occurs after the room
temperature falls below the set value by a few degrees (default 2 °C).
If STANDBY mode is not activated, or if the fume temperature has reached the set maximum value, the LCD display
shows the message MODULATE and the stove activates the flame modulation without any intervention by the user.
