  • Page 10 1-WARNINGS AND WARRANTY TERMS RULES FOR INSTALLATION The product is a boiler that uses wood pellets. Below is a list of the European regulations regarding the installation of the product: EN 303-5:2012: Solid fuel boilers, with manual or automatic loading, nominal thermal power of 500 kW - Terminology, requisites, tests and marking.

  • 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 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 12 2-INSTALLATION PRECAUTIONS REGARDING INSTALLATION IMPORTANT! Product installation and assembly must be carried out by qualified personnel. The product must be installed in a suitable place that allows easy access for it to be opened regularly and for routine maintenance to be performed.
  • Page 13 2-INSTALLATION POSITIONING AND RESTRICTIONS In the case of simultaneous installation with other heating appliances, provide appropriate air inlets for each one (according to the instructions of each product). The product cannot be installed (except for sealed or closed operation appliances with external ducted combustion air intake): •...
  • Page 14 2-INSTALLATION CONNECTION OF THE SMOKE EXHAUST DUCT When making the hole for the passage of the smoke discharge pipe, one must take into account the possible presence of flammable materials. If the hole must be made through a wooden wall or thermolabile material, the INSTALLER MUST first of all use the appropriate wall fitting (minimum diameter 13 cm) and suitably insulate the pipe of the product that passes through it using adequate insulating materials (1.3 - 5 cm thick with minimum thermal conductivity 0.07 W/m°K).
  • Page 15 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 16 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 18 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 chimney must be cleaned and checked by a skilled chimney sweep at least once a year.
  • Page 19 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).

    7-INITIAL START-UP GENERAL PRECAUTIONS Remove all components that could burn from the brazier and glass (manual, various adhesive labels and 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 the brazier in time for the fire to be regularly ignited.
  • Page 35 7-INITIAL START-UP This is absolutely normal as the structure is made of laminated steel and must not be considered a defect. It is extremely important to make sure the product is not immediately overheated and the temperature is increased gradually, initially using low power.
  • Page 36 7-INITIAL START-UP LOADING THE PELLETS Fuel is loaded by lifting the cover on the upper part of the product. Slowly pour the pellets into the hopper. Be careful as the cover could become very hot. LIFT THE COVER. INSERT THE PELLETS. No other type of fuel other then pellets, in compliance with above-mentioned specifications, is to be inserted into the hopper.
  • Page 37 7-INITIAL START-UP SAFETY PROCEDURE TO FOLLOW IF ANY SMOKE SPILLAGE IS SEEN WITHIN THE ROOM OR THE APPLIANCE SUFFERS FROM AN EXPLOSIVE IGNITION PLEASE TURN OFF THE APPLIANCE, VENTILATE THE ROOM AND CONTACT THE INSTALLER/ SERVICE ENGINEER IMIDIATLEY. User Training In ALL cases the installation and commissioning engineer MUST carry out a thorough handover of the appliance to the homeowner / end user.
