ATTENTION SURFACES CAN BECOME VERY HOT! ALWAYS USE PROTECTIVE GLOVES! During combustion, thermal energy is released that signifcantly increases the heat of surfaces, doors, handles, controls, glass, exhaust pipes, and even the front of the appliance. Avoid contact with those elements if not wearing protective clothing (protective gloves included).

FIRE SAFETY When installing the product, the following safety measures must be observed: a) In order to ensure sufition thermal insulation, respect the minimum safety distance from objects or furnishing components flammable and sensitive to heat (furniture, wood sheathings, fabrics. etc.) and from materials with flammable structure (see Picture 5- a).

The control regulation necessary in order to obtain nominal calorifc output is the following (see Cap. TECHNICAL DATA): Model nr. Mass of fuel hourly kg/h (A) Secondary Air (B) Prımary Air 4020 2,38 PRE-ADJUSTED PRE-ADJUSTED A – SMOKES control (Picture 7) (Conversion of the cooker function to the cooker, bake oven and heating function).
CHIMNEY POT The flue draught depends on the suitability of the chimney pot. It is therefore essential that, if built in a handcrafted way, the exit section is more than twice the internal section of the flue (Picture 2) . As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 3).

ALLOWED / NOT ALLOWED FUELS Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be loaded. The pieces of wood should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm. Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device, since these have a very high calorific value.
LIGHTING WARNING: After the first ignition you can smell bad odours (owing to the drying of the glue used in the garnitures or of the paint) which disappear after a brief using of the appliance. It must be ensured, in any case, a good ventilation of the environment. Upon the frst ignition we suggest loading a reduced quantity of fuel and slightly increasing the calorifc value of the equipment.
NORMAL OPERATION After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses and deformations (according to the instructions on paragraph TECHNICAL DESCRIPTION). You should always use the product with the door closed in order to avoid damages due to overheating (forge effect). The inobservance of this rule makes the warranty expire. For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearth must remain closed.
GLASS CLEANING Thanks to a specific inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with efcacy. Nevertheless this can never be avoided by using solid fuels ( particularly wet wood ) and it has not to be understood as a defect of the appliance. IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold device to avoid the explosion of the same.
PRODUCTS MADE OF NATURAL STONE (IF PRESENT) Natural stone has to be cleaned with very thin abrasive paper or with an abrasive sponge. DO NOT USEany cleanser or fluid. VARNISHED PRODUCTS (IF PRESENT) After some years of product use a change in the varnished details colour is totally normal. This is due to the considerable temperature range the product is subject to whenever in use and to the varnish ageing of time passing by.
