12-FIRST IGNITION WARNINGS BEFORE IGNITION GENERAL WARNINGS Remove any objects that may burn from the product 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.

12-FIRST IGNITION During the disposal phase of the residual heat, the fans operate at about 80% of their output and the speed cannot be varied. This is determined by the need for all the accumulated heat to be evacuated safely and quickly. The switch-off phase can last 15 - 30 minutes depending on the heat stored in the structure, determined by the duration and the operating regime of the product throughout the day.

14-MENU ITEMS 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-MENU ITEMS AND OPERATION EXTERNAL THERMOSTAT CONNECTION (optional) The room thermostat is not included with the stove and must be installed by a qualified technician. ATTENTION! The electrical wires must not come into contact with the hot parts of the stove. The temperature of the stove can also be controlled by an external room thermostat.

15-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).
16-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.

16-ALARMS Remembering that the draught recommended for the products to work properly is 10 Pa at maximum capacity and 5 Pa at minimum (according to the technical data sheet found in the user and maintenance manual), adjustments may be required in worse draught conditions (also due to the position of the flue in areas that are particularly subject to adverse weather such as prevailing winds, snow, northern exposure, etc.) so as to always guarantee the required negative pressure inside the hopper.

17-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.
18-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. CAUTION! All the cleaning operations of all parts must be performed with the product completely cold and the plug disconnected.
Page 23
18-CLEANING REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE SAFE IGNITION AND OPTIMAL OPERATION OF YOUR PELLET PRODUCT. IN CASE OF FAILED IGNITION AND AFTER ANY OTHER BLOCK STATE OF THE PRODUCT, IT IS ESSENTIAL TO EMPTY THE BRAZIER BEFORE EVERY RESTART 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.

18-CLEANING CLEANING THE STOVE CLADDING Below are a few indications to clean the metal cladding of the stove: • use only water, if necessary with the addition of neutral detergents (pH7) and characterised by light additives. • use only water on a cloth. There are electrical parts that could be damaged. •...

Page 26
18-CLEANING Use a flexible brush, approximately 1 m long, to scrape the walls of the firebox (see arrow - under plates “L” and “S” just removed) to make the ash fall into the lower compartment. Then thoroughly clean the lower exchanger, replace any gaskets if needed, and reassemble.

18-CLEANING CLEANING THE SMOKE EXPULSION SYSTEM 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.
Page 28
18-CLEANING TOP OUTLET CLEANING THE SMOKE BOX To remove ash from smoke box “A” remove the stove cladding (as indicated in the product manual), remove the four “x” screws, cap “V” and gasket “U”. Now, using the nozzle of a vacuum cleaner, remove any ash and soot that may have built up in box “A” (as indicated by the arrow).
Page 29
18-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.
Page 30
18-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.
19-TROUBLESHOOTING 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.
