Procedure to turn off the pellet boiler stove



Pellet feeding will stop immediately but the pellet boiler stove will continue working until the accumulated heat is fully consumed, turning itself off automatically after approx. 30 minutes.

REMARKS: The pellet boiler stove is fitted with an automatic device that allows cleaning the brazier after a given period of time: when this time is detected, the stove fire automatically reduces and ‹27.(+4'Œis shown on the display. After some minutes, the pellet boiler stove will start working regularly.

WARNING Do not unplug the power plug to turn off the pellet boiler stove; 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 - although switched off - 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.

Failure on electrical devices Failed light-up 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 stove switches off and you will read the words ‹#J?P0M#AAŒ on the display. ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ cooling phase is completed, clean the brazier and start a new light-up. Switching off while working The stove 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 stove continues working until the pellets left in the brazier ends. You will then read the words ‹#J?P0M(GPCŒ on the display and ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ alarm. Wait until the cooling phase is completed. Clean the brazier and start a new light-up.

These alarms remind you that the brazier must be cleaned and installed correctly before switching on the stove.

Smokes exhaust safety A mechanical depressor checks the correct depression for a proper smokes exhaust. On the contrary, if the flue is obstructed, the pellet boiler stove switches off and you will read the words ‹#J?P&CN(?GJŒ on the display. Pellets temperature safety In the rare event there is a too high temperature in the tank, the thermostat for pellets safety with manual reset creates an alarm #J?P5GA(?GJ stopping the pellet boiler stove. You need to reset the system working on the device placed on the back of the stove (Pict. 5)

Water temperature safety In the event the water temperature exceeds a limit value of 100°C, the thermostat for water safety lets the stove switch off. You will read the words ‹#J?P5GA(?GJŒon the display. Once you have waited a minimal time required for water cooling, you need to reset the thermostat placed on the back of the stove (fig. 5). Manual reset thermostat

There is no power supply In the event of a power drop longer than one minute, the pellet boiler stove can exhaust some smoke in the room: this causes no risks. As soon as you have the power supply again, the pellet boiler stove will have the words ‹%MMJ(GPCŒ on the display. After completing the cooling phase, the stove will start up again automatically according to the previous settings.

CAUTION! do not attempt to start the pellet boiler stove 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 stove again.

Electrical safety In the event of an electrical shock (lightning), the pellet boiler stove is protected by a fuse 2,5 A 250V which is placed on the back of the stove near the cable for power supply. Extract its box and replace the fuse.

CAUTION! the power socket where the pellet boiler stove 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.



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. 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.
