  • Page 51 12-ALARMS If all the above checks are negative, it is likely that the depression inside the stove drops due to poor performance of the flue, especially when the machine is operating at minimum speed for a long time. In this case it is possible to make small adjustments that allow you to increase the operating speed of the smoke fan to increase the depression inside the product, or make it less sensitive to the intervention of the pressure switch by changing its position mechanically.

    13-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.

  • Page 53: 14-Cleaning

    14-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 the plug disconnected.
  • Page 54 14-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 good quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of the component.
  • Page 55 14-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 the humidity compacting it over time.
  • Page 56 14-CLEANING CLEANING THE EXCHANGER CLEANING THE UPPER COMPARTMENT Clean the upper exchanger when the stove is cold and without cladding. After removing the cap for lower cleaning “N” (see previous paragraph), use a stiff rod or a bottle brush to scrape the firebox walls (see arrow) so that the ash falls into the lower compartment. Then remove the upper Calorite plate “H”;...
  • Page 57 14-CLEANING Use a stiff rod or a bottle brush to scrape the firebox walls (see arrow - at the right and left of the firebox respectively) so that the ash falls into the lower compartment. Use a vacuum cleaner nozzle to vacuum up any remaining ash and dust on the exchanger (see arrow). Technical Dept.
  • Page 58 14-CLEANING In the upper section, too, remove the front panel “E” (see the instructions in the dedicated paragraphs) and insert the nozzle of the vacuum cleaner to remove any deposits of dust. Then thoroughly clean the lower exchanger, replace any gaskets if needed, and reassemble.
  • Page 59 14-CLEANING CLEANING THE SMOKE DUCT AND GENERAL CHECKS Clean the smoke extractor system, especially around the “T” joints, 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.
  • Page 60 14-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 tank with a vacuum cleaner with a long pipe. We recommend removing the unused pellet from the tank because it can retain humidity. Disconnect any combustion air ducting that can lead humidity 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 CAT) during the necessary annual end of season scheduled maintenance operations.
