3.4 Overheating - pellet hopper temperature safety thermostat
3.5 Safety against flare-back in the pellet chute
The solutions preventing flare-back are:
►
negative pressure in the combustion chamber see par. 3.2.
►
the siphon shape of the pellet chute.
►
the hopper temperature safety see par. 3.4.
3.6 Overcurrent protection device
The unit is protected against overcurrent by 2A fuses on the power supply of the main stove switch located at the
back.
3.7 Power failure safety
In case of brief power failures, the stove relights automatically.
A temporary power failure does not limit stove safety and the hopper temperature does not reach high values
(< 85°C), given the small quantity of pellets burning in the brazier.
This anomaly can result in some smoke briefly escaping into the room, which does not involve any risk.
Do not tamper with the safety devices.
3.8 Fume extractor fan failure
If the fume extractor fan stops for any reason, the electronic controller instantly stops the pellet feed, displaying the
message 'AL 4 FAN FAIL'.
4 STOVE USE
The stove has the advantage of combining heat from a wood flame with the convenience of automatic control of
temperature and the possibility of programming lighting and shutdown.
4.1 Introduction
For safe and reliable use:

when lighting the first time, unpleasant odors 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; make sure the bag does not come into contact with the hot
surfaces of the insert;

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 insert must work only and exclusively 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 insert for the first time, make sure to allow it to get hot gradually without overheating;

during lighting, operation and shutdown, the insert may creak a little due to the heat expansion.
The insert is operated using a remote control provided with seven buttons and an LCD display. The remote control
enables insert lighting and shutdown, adjustment during operation and the setting of management programs.
The insert also has a button control panel, which can be used instead of the remote control if necessary, allowing
only some functions.
Given fig. 4.1 – 4.2 is the radio remote control and control panel with the main functions of the buttons.
A temperature probe is connected to a safety thermostat above the pellet chute
which automatically interrupts the pellet supply in case of excessive heating
> 85°C. In this case the extractor and/or fans continue working, allowing the stove
to cool down rapidly. The fault is displayed on the control panel with a message 'AL
7 THERMAL SAF'. In case of activation, proceed as follows:
Allow the stove to cool down for at least 45 minutes.
Reset the thermostat by pressing the button near the switch on the back of the
stove, after unscrewing the protection cap
(figure opposite).
Restart the stove normally.
