  • Page 10: 2-Installation

    2-INSTALLATION The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the domestic regulations in force. 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 11 If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly. If the floor is made of wood, it is recommended to fit a floor protection sheet in compliance with the Standards in force in the country of installation.

  • Page 12 2-INSTALLATION FOREWORD This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides indications for installing an efficient and correct smoke flue but is under no circumstances to substitute the regulations in force, which the qualified technician must be in possession of.
  • Page 13 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 15 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 functioning of the heater 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 16 2-INSTALLATION EXTERNAL AIR INLET It is mandatory to provide an adequate external air intake 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 35: 10-First Start-Up

    10-FIRST START-UP GENERAL PRECAUTIONS Remove any objects that may burn from the brazier (manual, various adhesive labels or any polystyrene). Check that the brazier is positioned correctly and rests properly on the base. The first start-up may not be successful as the feed screw is empty and does not always manage to load the required amount of pellets in time to light the flame.
  • Page 36 10-FIRST START-UP If the flame fails to ignite despite a regular supply of pellets, check the slignment of the brazier, which must rest snugly into its seating. If no anomaly is found during this inspection, there may be a problem with the product components or installation may not be correct.

  • Page 54 16-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 the humidity compacting it over time.
  • Page 55 16-CLEANING CLEANING THE COMFORT AIR STOVES LATERAL EXCHANGER With the stove cold, remove the top “A” and the first ceramic “C” on the right and left side of the stove (see the specific pages in this manual to remove the ceramics). Then remove the two screws “r”, the seal “S” and the plate “T” and clean the lateral walls of the firebox with a rigid rod or a bottle brush so that the dirt falls on the lower compartment.
  • Page 56 16-CLEANING CLEANING THE LOWER COMPARTMENT At this point you can loosen the four screws ‘’x’’ , remove plate ‘’U’’ and seal ‘’Z’’ and then clean the lower compartment where all the dirt deposits of the previous cleaning have accumulated.

  • Page 57 16-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 58 16-CLEANING END-OF-SEASON SHUTDOWN 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. When not in use the appliance must be disconnected from the mains power supply. It is recommended to remove the power cable for additional safety, especially in the presence of children.
