    13-FIRST START-UP WARNINGS BEFORE IGNITION GENERAL WARNINGS Remove all parts that may burn from the brazier and 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.

    37-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.
  • Page 51 37-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.
  • Page 52 In the event of breakage it must be replaced. ATTENTION! Never let the stove work without the air filter fitted. MCZ cannot be held liable for any damage caused to the internal components if this requirement is not complied with.
  • Page 53 37-CLEANING PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN CLEANING THE HEAT EXCHANGER AND THE LOWER COMPARTMENT 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 54 37-CLEANING CLEANING THE EXCHANGER CLEANING THE UPPER COMPARTMENT Clean the upper exchanger when the stove is cold and without the cladding in question. 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 55 37-CLEANING Use a stiff rod or a bottle brush to scrape the walls of the firebox (see arrow - respectively to the right and to the left of the firebox) to make the ash fall into the lower compartment. Use a vacuum cleaner nozzle to vacuum up any remaining ash and dust on the exchanger (see arrow). Then thoroughly clean the lower exchanger, replace any gaskets if needed, and reassemble.
  • Page 56 37-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 57 37-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.
