  • Page 11: 2-Installation

    2-INSTALLATION The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the regulations in force in the country of installation. PELLETS Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders.
  • Page 12 2-INSTALLATION FOREWORD The installation position must be chosen according to the room, smoke extraction system and flue. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimneypot. The manufacturer declines all responsibility in the event of installations that do not comply with the laws in force, incorrect room air exchange, electrical connection non-compliant with the standards and inappropriate use of the appliance.
  • Page 13 2-INSTALLATION FOREWORD The Chimney Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides indications for installing an efficient and correct flue but is under no circumstances to substitute the regulations in force, which the qualified technician must be in possession of.
  • Page 14 2-INSTALLATION TECHNICAL CHARACTERISTICS Have the efficiency of the flue checked by an authorised technician. The flue must be sealed against flue gasses, in a vertical direction without narrowing, be made with materials impermeable to smoke, condensation, thermally insulated and suitable to resist normal mechanical stress over time (we recommend fireplaces made of A/316 or refractory material with insulated round section double chamber).

  • Page 16 2-INSTALLATION MAINTENANCE The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the efficient operation of the stove and, if large build-ups accumulate, can catch fire. The flue and chimneypot must be cleaned and checked by a qualified chimney sweep at least once a year.
  • Page 17 2-INSTALLATION EXTERNAL AIR INLET It is mandatory to provide an adequate external air inlet that supplies the combustion air required for the product to work properly. The flow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b).
  • Page 18 2-INSTALLATION In order to fully enhance the sealed features and heating performance of this Oyster appliance, and thus to avoid fitting a free air intake in the room, It is recommended to connect the air required for combustion directly to the external air intake through 060 mm piping with a maximum length of 3 linear metres, using the suitable “j”...

All the cleaning operations of all parts must be performed with the product completely cold and the plug disconnected.
  • Page 51 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 52 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 53 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 54 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).
  • Page 55 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. Technical Dept.
  • Page 56 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 57 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.
