11-FIRST START-UP WARNINGS BEFORE IGNITION GENERAL WARNINGS Remove any objects that may burn from the product brazier and from the glass (manual, various adhesive labels or any polystyrene). Check that the brazier is positioned correctly and rests properly on the base. The first ignition may not be successful as the feed screw is empty and does not always manage to load the brazier with the required amount of pellets in time to light the flame.

13-MENU ENTRIES AND OPERATION h - Pellet Recipe This function is for adapting the stove to the type of pellet in use. As there are many types of pellets available on the market, operation of the stove can vary considerably according to the quality of the fuel. When the pellets clog up the brazier due to excess loading of fuel or when the flame is always high even at low power, or when the flame is low, it is possible to decrease/increase the amount of pellets in the brazier: The available values are:...

14-SAFETY DEVICES SAFETY DEVICES The product is fitted with the following safety devices PRESSURE SWITCH Monitors pressure in the smoke duct. It is designed to shut down the pellet feed screw in the event of an obstructed flue or significant back-pressure (from wind) SMOKE TEMPERATURE PROBE Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset...
15-ALARMS ALARM SIGNALLING When an operating condition other than the one expected for regular stove operation occurs, an alarm is triggered. The reason for the alarm is shown on the control panel. The sound signal is not enabled for alarms A01-A02 in order not to disturb the user when there is an absence of pellets in the hopper during the night.
15-ALARMS ALARM RESET To reset the alarm, press and hold key 1 (ESC) for a few seconds. The stove checks whether or not the cause of the alarm is ongoing. In the first case, the alarm continues to be displayed, in the second case it turns OFF. If the alarm persists, contact a service centre.
Page 18
15-ALARMS PRESSURE SWITCH CHECK (A21/A05) This check must only be carried out by a licensed operator. During commissioning and at each periodic maintenance operation, or in the event of an A21 (or A05) alarm trip not justified by unforeseen openings/obstructions, check that the pressure switch signal is in order: Switch on the device and set it to minimum power.
16-RECOMMENDATIONS FOR SAFE USE ONLY CORRECT INSTALLATION AND APPROPRIATE MAINTENANCE AND CLEANING OF THE APPLIANCE CAN GUARANTEE CORRECT OPERATION AND SAFE USE OF THE PRODUCT. We would like to inform you that we are aware of cases of malfunctioning of domestic pellet-fuelled heating products, mainly due to incorrect installation and use, as well as inadequate maintenance.
17-CLEANING EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER Only by properly servicing and cleaning the product is it possible to ensure its safety and correct operation. ATTENTION! All the cleaning operations of all parts must be performed with the product completely cold and unplugged. Disconnect the product from the 230V power supply before performing any maintenance operation The product requires little maintenance if used with certified good quality pellets.
17-CLEANING For the brazier to be cleaned properly, remove it from its housing completely and thoroughly clean all the holes and the grate on the bottom. If high quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of the component.
17-CLEANING PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN CLEANING THE HEAT EXCHANGER Half-way through the winter season, but especially at the end, the compartment through which the exhaust smoke passes will need to be cleaned. This cleaning process is mandatory in order to facilitate the general removal of all combustion residue, before it becomes very difficult to remove it due to moisture compacting it over time.
Page 23
17-CLEANING CLEANING THE EXCHANGER CLEANING THE UPPER COMPARTMENT Clean the upper exchanger when the stove is cold and without cladding. After removing the cap to clean the lower compartment “n” (see previous paragraph), use a stiff rod or a bottle brush to scrape the walls of the firebox (see arrow) to make the ash fall into the lower compartment.
Page 24
17-CLEANING PERIODICAL CHECK OF THE DOOR CLOSURE Make sure the door closure ensures a correct sealing action (with the “paper sheet” test) and that when the door is closed, the closing block (X in the figure) does not protrude from the sheet metal to which it is secured. For some products it will be necessary to disassemble the cladding to be able to assess the anomalous protrusion of the block when the door is closed.
17-CLEANING CLEANING THE SMOKE DUCT AND GENERAL CHECKS Clean the smoke outlet system, especially around the Tee fittings, elbows and any horizontal sections of the smoke duct. For information on periodically cleaning the flue, contact a skilled chimney sweep. Check the seal of the ceramic fibre gaskets on the door of the stove. If necessary, order new replacement gaskets from the retailer or contact an authorised service centre to carry out the operation.
17-CLEANING SHUTDOWN (end of season) At the end of each season, before switching the product off, it is recommended to remove all the pellets from the hopper with a vacuum cleaner with a long pipe. We recommend removing the unused pellets from the hopper because they can retain moisture. Disconnect any combustion air ducting that can lead to moisture inside the combustion chamber but, above all, ask the specialised technician to refresh the paint inside the combustion chamber with the special silicone spray paints (available at any store or Technical Assistance Centre) during the necessary annual end of season scheduled maintenance operations.
18-FAULTS/CAUSES/SOLUTIONS ATTENTION: All repairs must only be carried out by a specialised technician, with the product switched off and unplugged. ANOMALY POTENTIAL CAUSES SOLUTIONS The pellets are not fed into The pellet hopper is empty Fill the hopper with pellets. the combustion chamber.
