Binding agents % of pressed mass <2 2 <2 Not more than 20% of the pellet may have a length greater than 7.5 times its diameter D. The DIN prohibits the use of any added substance. However, this prohibition is not valid for small heating systems. DIN plus proposes the combination of the qualitative parameters proposed by standard DIN 51731 and by Austrian standard Önorm M 7135. The pellet, as also stipulated by current Italian legislation governing the commercial technology characteristics of fuels (DPCM 2.10.1995) must be produced exclusively with untreated wood chippings, with no other added materials. It is strictly prohibited to use any solid or liquid fuel other than the pellet to feed the stove. In order to optimise the use of the product we recommend using pellets which have been given a quality certificate by an authorised body. The use of pellets other than those directed by the installer may lead to heater malfunction and to the guarantee becoming invalid. ...

A high moisture content in the pellet may cause it to crumble into dust, that creates a greater accumulation of residue in the brazier area and blockage of the fuel feed system (auger). ...
2 INSTALLATION INS . For a correct installation of the heater and to prevent the uprising of possible problems during running the heater, we are supplying some simple recommendations for the installation – according to regulations UNI 10683, UNI 9615 , UNI 9731 , UNI‐CIG 7129 and following updating referred to domestic gas use units. 2.1 Indoor positioning Our product is a heater that draws air that is necessary for its combustion process directly from the environment to be heated. For this reason and for the even more important reason of safety for the people using it, the heater ...
Page 10
In compliance with the indications reported under regulation UNI 10683 , the air inlets must have the following features : 1.They must have a clear space of not less than 80 cm ; 2.They must be made at a height close to the floor; 3.They must be suitably protected by a wire mesh or grille in such a way that the minimum passage space is not and may not be reduced; 4.They must be placed in such a way that they are not obstructed in anyway. The correct inflow of fresh air may be guaranteed by using apertures ...
Page 11
Having placed the outermost overall part of the heater at a distance of 80 cm from combustible and/or flammable material, if this distance cannot be maintained it is useful to arrange for heat protection to be provided ( regulations UNI 7129 , UNI 10683) Do not get close to, and above all do not touch with flammable material the outer surfaces of the combustion chamber that, after continuous product use, may reach high temperatures . ...
2.2 Fume extraction flue features The main features characterising the fume extraction flue are given. They are based on what is set out in standards UNI 7129 and UNI 10683/98: ‐ Inspection valves (I); ‐ Minimum height of the pipe directly connected to the heater fume extraction outlet must be between 2 ‐ 3 m; ‐ If it is necessary to have a horizontal section, it is advisable to make it with a maximum length of 1.5 m and with an incline of 3 ‐ 5% in order to help the fumes to escape; ‐ Use of a cowl that is wind‐resistant and rain‐resistant in order to avoid a change in the slight condition of overpressure the flue is in, (it is strongly recommended not to use a horizontal section at the end of the flue). The reduction in pressure in the flue is necessary so as to help the normal flow of fumes ...
Page 13
Figure 2.3: Fume extraction flue In the room where the heat generator must be installed, there must be no fume‐ extraction hoods already in existence or installed, in order to avoid depressing the atmosphere. The air vents must not be closed. Keep the flue clean, performing a cleaning operation at least once a year; it is also advisable to clean both the flue cowl and the fume pipe connection. ...
2.2.1 Outside wall extraction One of the installation solutions that may be adopted is that of placing the pellet heater close to an outside wall of the room so that the fumes are extracted directly to the outside (figure 2.4). Hereafter please find some recommendations reported under regulation UNI 7129 referred to this particular plant: ‐ Always guarantee that there is an inspection valve (I) that will allow effective and periodic cleaning to be carried out, and any condensation formed to be eliminated; ‐ The cowl (T) must be strictly windproof and rainproof; ‐ Insulate the fume extraction flue appropriately in the section where it goes through the wall. The fume extraction flue that is completely outside must be made of double‐wall stainless steel in order to guarantee that there is both greater resistance to atmospheric agents and correct fume extraction temperature. ...
2.2.2 Roof extraction by means of a traditional flue Pellet combustion fumes may be extracted also using a pre‐existing traditional flue (figure 2.5), provided that it is made to standard (refer to standard UNI 10683). Below is a short list of some of the main features given in the standard that characterise a good chimney (C): ‐ Suitable insulation and proofing particularly in its outer section that is exposed to the weather; ‐ Uniform internal section (there must be no section restrictions); ‐ Made of material that is resistant to high temperatures, the action of combustion products and the corrosive action of any condensation formed; ...
Page 16
We recommend to follow indications reported under regulations UNI 9615 and 9731 referred to dimensions of the chimney ( C ) and however to avoid using sections smaller than 100 mm . In the case where there are larger sections, it is necessary to insert a steel pipe (A) inside the masonry one (C), as shown in figure 2.6. The steel flue pipe must be suitable insulated with a high temperature‐resistant rock wool or vermiculite material (B). Figure 2.6: Example of extraction flue connection. In the case of fire in the extraction flue or duct, switch off the heater immediately and disconnect it from the house mains power supply. ...

2.3 Connection to Central heating system In order to be able to operate, the heater must be suitably connected to a heating system. For this type of installation also, some simple suggestions are provided that will undoubtedly be helpful when installing the product (refer to regulation UNI 10412 and following up‐dating) The drainage cock is placed at the lowest point of the water circuit. We recommend to install the ball valve on the delivery water pipe and on the return water pipe ( please refer to the enclosed schematic drawing) . This will enable a quick and easy maintenance operation in case of need. All water heating installations should be designed, before product installation, and installed by a competent heating engineer in accordance with BS 5449: 1990; Code of Practice for Central Heating Systems for Domestic Premises. Further guidance is available from the following sources: BS EN 14336: 2004 Heating Systems in Buildings. Installation and commissioning of water based heating systems. BS EN 12828: 2003; Heating Systems in Buildings. Design of water based heating systems. BS EN 12831: 2003; Heating Systems in Buildings. Method for calculation of the design heat load. ...
The ball valve mounted on the inlet pipe must be open in normal system operating conditions in order to allow water to be added to the boiler. It may be closed when it is necessary to drain the system. The delivery and return pipes have a diameter of ¾". The correct functioning of the “ expansion box open ” requires that the expansion box is placed at a height not less than 7 meters in respect to the stove. The expansion vessel must be made of a covered vessel located above the highest point reached by the water in the system. The safety, inlet and outlet pipes must be protected from ice where this may occur. The safety pipe must allow the highest part of the generator to be in contact with the atmosphere ...

The cleaning operations described below must be carried out only when the heater is totally cold and disconnected from the household mains power supply. Disconnection from the household mains power supply is obtained by means of two simple operations: the first consists of turning off the switch placed at the back of the heater and the second of removing the product power cable (from the socket on the wall or from the rear of the apparatus). Figure 3.1: Pan grille The grille at the base of the pan (figure 3.1) is cleaned automatically during the heater extinguishing stage in order to ensure at all times the correct inflow of burning air in the combustion chamber. Should residue pellet accidentally remain, remove it by hand or with the ...

panel itself is dismounted by loosening the screw positioned right in front of the burning pot ; the opening of the tray system is reached by removing the wing screws . Once the cleaning process has been completed and all the ashes have been removed by vacuum or by using the specific brush delivered together with the stove, all trays must be replaced and well tightened . The above cleaning process should be achieved using the specific cleaning brush supplied with the stove or a vacuum cleaner. At the end of the winter, we recommend emptying the fuel tank of residue pellet and storing it according to the methods suggested in chapter one. We recommend a thorough cleaning of both the flue and the fume junction (at least once during the whole operating season) in order to prevent fire risks. 3.2 Yearly maintenance This paragraph, intended expressly for engineers and all specialised personnel required to work on our product, is aimed at providing useful instructions in order to perform the necessary work for keeping the apparatus operating at a high level of efficiency. Unscheduled maintenance of the system must be carried out by qualified personnel when the heater is cold and disconnected from the household mains power supply. ...

Figure 3.5. : Slide slits The slit will only be visible after its cover has been removed. Now it is possible to perform the cleaning, using the brush. Every 2 years it is necessary to clean the steel fan of the fume extractor and its housing. This part can be reached after having removed the side ceramic panels and after removing the four screws that hold the fan. The cleaning can be performed more easily with a vacuum cleaner. In this model the heat exchangers can be reached by means of the openings positioned at the rear of the stove. When replacing the covers of the side slits it will be necessary to remove the rear panel by loosening some screws. When replacing the parts and components , we would recommend the ...

In order to optimise the product using different quality pellets and different installation methods , the heater allows an appropriate method of operation of combustion and heating to be chosen according to 4 methods . the methods run from 1 to 4 . Each number corresponds to a ventilation receipt . For example method n. 1 is suitable for operating a clearer pellet and with a flue installed according to regulations ( lower ventilation required)‐ method n. 4 is suitable for a darker pellet and with a non standard flue ( more ventilation required). At last whereas you are not able to locate an efficient combustion method , the manipulation of the parameters can be carried out by qualified engineers from Vokera Ltd . The engineers will analyze the situation and they will recommend a suitable solution for the situation . For a correct operation of the heater , we recommend to set power 4 or 5 during lighting sequence and for the following few minutes of functioning .
