Chapter 3 WHAT IS THE PELLET? Pellets are realised by subjecting wood shavings i.e. the rejects of pure wood (without paint) sawmill, carpenter products and products from other activities connected to working and transforming wood, to very high pressures. This type of fuel is absolutely ecological as no glues are used to hold it together. In fact, the compactness of the pellets is guaranteed through time by a natural substance that is found in wood: lignin.
Chapter 4 SAFETY DEVICES FLUE EXHAUST BREAKAGE If the suction device stops, the electronic board immediately blocks the pellet supply. PELLET FEED MOTOR STOP If the motor reducer stops for any reason, the stove goes into alarm mode and the fumes motor continues to function in order to expel all combustion gas until the minimum cooling level is reached. DOOR MICRO SWITCH When the stove door is opened, a safety micro switch blocks fuel feeding.
Chapter 4 WATER OVERHEATING SAFETY VIA 100° C BULB When the temperature of the water inside the product is in proximity of 100°C, pellet feeding is blocked. If the bulb trips, restoration of the safety device is manual and must be performed by an authorised technician. The restoration of 100°C safety device is not under warranty unless the after-sales centre can show the presence of a faulty component.
Chapter 4 Adjustment automatic circuit breaker switch Automatic circuit breaker switch (block thermostat) Circulation system Expansion system* Safety dissipation system incorporated with the generator with thermal safety valve (self-activated), whenever the appliance does not have a temperature self-adjustment system. The temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from the flow connection.

Chapter 5 ASSEMBLY AND INSTALLATION INSTRUCTIONS The installation must be in compliance with: UNI 10683 (2005) heat generators fed with wood and other solid fuels: installation. The chimneys have to be in compliance with: UNI 9731 (1990) chimneys: classification based on thermal resistance. EN 13384-1 (2006) chimneys thermal and fluid-dynamics calculation method. UNI 7129 point 4.3.3 Fire Department dispositions, local rules and prescriptions. UNI 1443 (2005) chimneys: general requisites.
Chapter 5 SMOKE EVACUATION SYSTEMS Flue gas exhaust system independent from the appliance constituted by a fitting or smoke channel, chimney or individual flue and chimney cap. FORCED DRAUGHT Air circulation by means of the fan activated by electric motor. NATURAL DRAUGHT Draught which determinates in a chimney/flue for effect of the volume mass difference existing between smoke (hot) and surrounding atmosphere air, without any mechanical intake aid installed inside it or at its peak.
Chapter 5 CONNECTION TO THE SMOKE EVACUATION SYSTEM SMOKE CHANNEL OR CONNECTIONS To mount the smoke channels, non-flammable elements will have to be used, ideal for resisting fuel products and their eventual condensing. The use of flexible metal and asbestos cement pipes to connect the appliances to the flue is forbidden, even for pre-existing smoke channels. There must be continuity between the smoke channel and the flue so that the flue does not lean on the generator.
Chapter 5 It is forbidden to have other air supply channels and pipes for plant engineering, especially if over-sized, transit inside the smoke channels. The mounting of manual draught adjustment devices on forced draught appliances is forbidden.

Chapter 5 APPLIANCE CONNECTION TO THE FLUE AND FUEL PRODUCTS EVACUATION The flue must receive the discharge from only one heat generator. The direct discharge towards closed spaces is forbidden, even with clear sky. The direct discharge of the fuel products must be at roof and the smoke pipe must have the features provided in the “Chimney or individual flue” section.

Chapter 6 HYDRAULIC SYSTEM Certain concepts referring to Italian normative UNI 10412-2 (2006) are described in this chapter. As previously described, when installing, all national, regional, provincial and town council Standards in force provided by the country in which the appliance has been installed must be complied with. TYPE OF SYSTEM There are two different types of plant: Open vessel plant and closed vessel plant. The product has been designed and realised to work with closed vessel systems.
Chapter 6 SAFETY VALVES The load capacity of the safety valve must allow the discharge of a quantity of vapour, not lower than: Q / 0,58 [kg/h] where: Q is the useful outlet power to the generator water expressed in kilowatt. The diameter of the minimum net transversal section of the valve inlet must not be lower than 15 mm. The valve load pressure, equal to the calibration pressure, increased by the overpressure, cannot exceed the maximum exercise pressure of the heat generator.
Chapter 6 Where it is necessary to separate the individual heat generator from the expansion vessel or expansion vessels unit, a three-way tap must be applied on the connection piping between the generator and the vessel, in order to ensure, in every position, the connection of the generator with the expansion vessel or with the atmosphere. The expansion vessels, the connecting pipes, the bleed pipes and drain pipes must be protected from freezing, where this phenomenon occurs.

Display D2 to view the power set.
Chapter 7 BASIC INSTRUCTIONS The stove you have purchased uses pellet fuel. This type of material is obtained from natural waste from the machining of wood. By means of a special process that does not require the use of any binding agent and additive, the waste is compressed in industrial machinery under high pressure and they become solid wooden pellets. IT IS PROHIBITED TO BURN NON-PELLETISED RAW MATERIALS INSIDE OUR STOVES.
Chapter 7 WATER TEMPERATURE ADJUSTMENT The appliance can control the water temperature through a digital probe which automatically adjusts the machine functioning when nearing the desired temperature. When the stove is started and has entered normal functioning mode, display D1 will shows the water temperature. Adjust the desired water temperature using keys 2 and 3.
Chapter 7 PUMP FUNCTIONING The standard installation of the pump inside the product starts the water circulation when the temperature of the water inside the stove reaches approx. 60°C. The pump will always function to circulate the water inside the plant, unless the water returning to the stove is below 60°C. As soon as the product switches on, it is normal for the pump to function intermittently, given the thermal exchange with the plant.
