4 WARNINGS FOR USE IN SAFETY CONDITIONS ENGLISH FOREWORD These warning notes are aimed at ensuring the safe use of the components of heating systems for civil use and the production of hot water. They indicate how to act to avoid the essential safety of the components being compromised by incorrect or erroneous installation and by improper or unreasonable use. The warning notes provided in this guide also seek to make the consumer more aware of safety problems in general, using necessarily technical but easily understood language. The manufacturer is not liable contractually or extra contractually for any damage caused by errors in installation and in use, or where there has been any failure to follow the manufacturer s instructions. GENERAL WARNING NOTES The instruction booklet is an integral and essential part of the product and must be given to the user. Carefully read the warnings in the booklet as they contain important information regarding safe installation, use and maintenance. Keep the booklet to hand for consultation when needed. Equipment must be installed in accordance with current regulations, with the manufacturer s instructions and by qualified technicians. By the term qualified technicians is meant persons that are competent in the field of heating components for civil use and for the production of hot water and, in particular, assistance centres authorised by the manufacturer. Incorrect installation may cause damage or injury to persons, animals or things. The manufacturer will not in such cases be liable. After removing all the packaging make sure the contents are complete and intact. If in doubt do not use the equipment and return it to the supplier. The packaging materials (wooden crates, nails, staples, plastic bags, expanded polystyrene, etc.) must not be left within reach of children as they may be dangerous to them. They should also be collected and disposed on in suitably prepared places so that they do no pollute the environment. Before carrying out any cleaning or maintenance, switch off the equipment at the mains supply, using the system s switch or shut-off systems. If there is any fault or if the equipment is not working properly, de-activate the equipment and do not attempt to repair it or tamper with it directly. In such case get in touch with only qualified technicians. Any product repairs must only be carried out by BALTUR authorised assistance centres using only original spare parts. Failure to act as above may jeopardise the safety of the equipment. To ensure the efficiency and correct working of the equipment, it is essential to have periodic maintenance carried out by qualified technicians following the manufacturer s instructions. If the equipment is sold or transferred to another owner or if the owner moves and leaves the equipment, make sure that the booklet always goes with the equipment so it can be consulted by the new owner and/ or installer. For all equipment with optionals or kits (including electrical), only original accessories must be used. BURNERS This equipment must be used only for its expressly stated use: applied to boilers, hot air boilers, ovens or other similar equipment and not exposed to atmospheric agents. Any other use must be regarded as improper use and hence dangerous. The burner must be installed in a suitable room that has ventilation in accordance with current regulations and in any case sufficient to ensure correct combustion Do not obstruct or reduce the size of the burner air intake grills or the ventilation openings for the room where a burner or a boiler is installed or dangerous mixtures of toxic and explosive gases may form. Before connecting the burner check that the details on the plate correspond to those of the utility supplies (electricity, gas, light oil or other fuel). Do not touch hot parts of the burner. These, normally in the areas near to the flame and any fuel pre-heating system, become hot when the equipment is working and stay hot for some time after the burner has stopped. If it is decided not to use the burner any more, the following actions must be performed by qualified technicians: a) Switch off the electrical supply by disconnecting the power cable from the master switch. b) Cut off the fuel supply using the shut-off valve and remove the control wheels from their position. c) Render harmless any potentially dangerous parts. Special warning notes Check that the person who carried out the installation of the burner fixed it securely to the heat generator so that the flame is generated inside the combustion chamber of the generator itself. Before starting up the burner, and at least once a year, have qualified technicians perform the following operations: a) Set the burner fuel capacity to the power required by the heat generator. b) Adjust the combustion air flow to obtain combustion yield of at least the minimum set by current regulations. c) Carry out a check on combustion to ensure the production of noxious or polluting unburnt gases does not exceed limits permitted by current regulations. d) Check the adjustment and safety devices are working properly. e) Check the efficiency of the combustion products exhaust duct. f) Check at the end of the adjustments that all the adjustment devices mechanical securing systems are properly tightened. g) Make sure that the use and maintenance manual for the burner is in the boiler room. If the burner repeatedly stops in lock-out, do not keep trying to manually reset but call a qualified technicians to sort out the problem. The running and maintenance of the equipment must only be carried out by qualified technicians, in compliance with current regulations. 2 / 18

5 ELECTRICAL SUPPLY The equipment is electrically safe only when it is correctly connected to an efficient ground connection carried out in accordance with current safety regulations. It is necessary to check this essential safety requirement. If in doubt, call for a careful electrical check by a qualified technicians, since the manufacturer will not be liable for any damage caused by a poor ground connection. Have qualified technicians check that the wiring is suitable for the maximum power absorption of the equipment, as indicated in the technical plate, making sure in particular that the diameter of cables is sufficient for the equipment s power absorption. Adapters, multiple plugs and extension cables may not be used for the equipment s power supply. According to current safety regulations, an omnipolar switch with a contact opening gap of at least 3 mm is required for the mains supply connection. Extract the power cable external insulation as strictly necessary for the connection, in order to avoid that the cable comes into contact with metal parts. An ominpolar switch in accordance with current safety regulations is required for the mains supply connection. The electrical supply to the burner must have neutral to ground connection. If the ionisation current has control with neutral not to ground it is essential to make a connection between terminal 2 (neutral) and the ground for the RC circuit. The use of any components that use electricity means that certain fundamental rules have to followed, including the following: - do not touch the equipment with parts of the body that are wet or damp or with damp feet - do not pull on electrical cables - do not leave the equipment exposed to atmospheric agents (such as rain or sun etc.) unless there is express provision for this. - do not allow the equipment to be used by children or inexpert persons. The power supply cable for the equipment not must be replaced by the user. If the cable gets damaged, switch off the equipment, and call only on qualified technicians for its replacement. If you decide not to use the equipment for a while it is advisable to switch off the electrical power supply to all components in the system that use electricity (pumps, burner, etc.). Have qualified technicians check the following: a) that the feed line and the train comply with current law and regulations. b) that all the gas connections are properly sealed. Do not use the gas pipes to ground electrical equipment. Do not leave the equipment on when it is not in use and always close the gas tap. If the user of is away for some time, close the main gas feed tap to the burner. If you smell gas: a) do not use any electrical switches, the telephone or any other object that could produce a spark; b) immediately open doors and windows to create a current of air that will purify the room; c) close the gas taps; d) ask for the help of qualified technicians. Do not block ventilation openings in the room where there is gas equipment or dangerous situations may arise with the build up of toxic and explosive mixtures. FLUES FOR HIGH EFFICIENCY BOILERS AND SIMILAR It should be pointed out that high efficiency boilers and similar discharge combustion products (fumes) at relatively low temperatures into the flue. In the above situation, traditional flues (in terms of their diameter and heat insulation) may be suitable because the significant cooling of the combustion products in these permits temperatures to fall even below the condensation point. In a flue that works with condensation there is soot at the point the exhaust reaches the atmosphere when burning light oil or heavy oil or the presence of condensate water along the flue itself when gas is being burnt (methane, LPG, etc.). Flues connected to high efficiency boilers and similar must therefore be of a size (section and heat insulation) for the specific use to avoid such problems as those described above. ENGLISH GAS, LIGHT OIL, OR OTHER FUEL SUPPLIES General warning notes Installation of the burner must be carried out by qualified technicians and in compliance with current law and regulations, since incorrect installation may cause damage to person, animals or things, for which damage the manufacturer shall not can be held responsible. Before installation it is advisable to carry out careful internal cleaning of all tubing for the fuel feed system to remove any residues that could jeopardise the proper working of the burner. For first start up of the equipment have qualified technicians carry out the following checks: If you decide not to use the burner for a while, close the tap or taps that supply the fuel.

8 ENGLISH BURNER CONNECTION TO THE BOILER AND CONNECTION TO THE GAS PIPELINE The burner is equipped with a sliding connection flange on the combustion head. When connecting the burner to the boiler, it is necessary to correctly position the flange so that the combustion head enters the furnace to the extent specified by the boiler manufacturer. When the burner has been correctly connected to the boiler, proceed with connecting it to the gas pipeline (see 8780). The gas supply pipe must be suitably sized for the pipe length and gas supply according to the regulations in force. It must be perfectly airtight and should be properly checked before testing the burner. It is essential to install on this piping, near the burner, a suitable connector to allow an easy disassembly of the burner and/or the opening of the boiler door. FOR BURNER WITH DUNGS GAS VALVE model MB... The DUNGS valve mod. MB... valve incorporates a filter and a gas pressure stabilizer and, therefore, only a shut-off valve and an anti-vibration joint have to be fitted onto the gas supply pipeline (see 8871). Only if the gas pressure is higher than the minimum level permitted /400 mm A.C.), a suitable pressure reducer must be installed on the gas pipeline outside the heating plant. We recommend installing an elbow directly on the burner gas train before fitting the detachable coupling. This layout makes it possible to open the boiler door, if there is one, after the coupling itself has been opened (see 8871). HYDRAULIC CONNECTIONS (DIESEL FUEL) The burner tank connection pipe must be perfectly airtight. It is recommended to use copper or steel pipes of a suitable diameter (see tables and drawing). At the end of the rigid pipes, fuel shut-off gate valves must be installed. Filter, flexible hoses and connection nipples are supplied with the burner. The pump is provided with specific connections (see figure) to fit control instruments (manometer and vacuum gauge). For a safe and silent operation, the suction vacuum cannot exceed 4.6 m C.A., that is to say 35 cm Hg. Max. pressure on suction and return 1.5 bar.

10 GENERAL OUTLINE DIAGRAM OF HYDRAULIC CIRCUIT PREPARATION FOR DIESEL FUEL IGNITION ENGLISH Return Suction Foot valve Diesel fuel solenoid valve Diesel fuel pump pressure 12 bar. ELECTRICAL CONNECTIONS Nozzle 8502cmt18.tif Electric lines should be placed at an adequate distance from hot parts. We advise you to carry out all connections by using flexible electrical wire, with a section suitable for the available voltage and absorbed power. Maximum absorbed power = 600 VA Supply line minimum section = 1.5 mm 2 with 230V FURTHER INSTRUCTIONS TO START A MIXED BURNER Make sure the fitted nozzle, with a spray angle of 60, is suitable for the boiler capacity. The table shows the delivery values in kg/h of diesel fuel depending on nozzle size and pump pressure (generally 12 bar). Note that 1 kg diesel fuel provides 10,200 kcal. Make sure the combustion mouth enters the combustion chamber as required by the boiler manufacturer. Make sure that the return pipe to the tank has no clogging, e.g. closed gate valves, plugs, etc. Any obstacle would break the sealing element placed on the hose or on the pump shaft. Open the air venting device installed on the pump, loosening it by a few turns. Disconnect the wire powering the pump motor and connect it, temporarily, to the terminal No. X1.56 of the "input terminal board" to feed the pump motor. Close the switch on the burner and the main switch and make sure that rotation direction is correct. The pump motor is activated and starts the diesel fuel suction pump. When diesel fuel flows out of the air venting device, open the main switch to stop the motor. Restore the original connections to the corresponding terminals. The burner is now ready for diesel fuel operation. It is advisable to first carry out the start-up with liquid fuel, because in this case the delivery is conditioned by the used nozzle, whereas methane gas delivery can be varied as you like using the corresponding flow rate regulator. In the case of an automatic burner, the fuel change switch operates on a cyclic relay which activates the components for the use of both fuels (valves, pressure switches, pump etc.) thanks to an auxiliary relay. It takes about 10 seconds for the cyclic relay to carry out its program. It is therefore necessary to leave it in this position to for at least 10 seconds, after moving the fuel change switch from gas to diesel fuel or vice versa. This condition is necessary to allow the cyclic relay to carry out its program. If the switch is moved from a position to the other before the! period of 10 seconds, the cyclic relay stops in the middle of its program not allowing to use the burner with both gas and diesel fuel.

11 IGNITION AND ADJUSTMENT WITH DIESEL FUEL Make sure that motors (fan and pump) turn in the right direction. Make sure that the discharge of combustion products can take place freely (chimney gates should be open) and that there is water in the boiler. Open the combustion air regulator as necessary and open the air passage between the head and the disk by about a half, using the adjusting screw of the flame disk. Close the main switch and the burner switch to activate the burner and wait for it to start. The burner is therefore activated and carries out the preventilation phase. If the air pressure exceeds the value at which the air pressure switch has been set, the diesel fuel valve will be activated. With the burner on, adjust combustion air delivery, if necessary. The burner is equipped with a device which optimises combustion by decreasing and increasing the air flow between disk and head. The maximum smoke rate allowed is No 2 of Bacharach scale, with a carbon dioxide value (CO2) ranging from 10 to 13%. Usually, you need to decrease the air flow between disk and head when the burner works with reduced fuel delivery. The air flow must be proportionally larger when the burner works with an increased fuel delivery. Use the flame disk adjusting screw to adjust air flow. When modifying this position, it is necessary to check that ignition occurs correctly. IGNITION AND ADJUSTMENT WITH METHANE GAS In order to proceed with ignition, it is necessary to vent the air contained in the pipeline and to check, in case of a three-phase burner, that the motor rotates in the right direction. Then proceed as follows: Make sure that the discharge of combustion products can take place freely (chimney gates should be open) and that there is water in the boiler. Open the combustion air regulator as necessary and open the air flow between head and disk by one third using the adjusting screw of the flame disk. Use the regulators incorporated in the gas valves in such a way as to obtain the gas delivery presumed necessary. See the specific table for the gas delivery adjustment based! on the type of valves fitted on the burner page 15. Power the burner by turning on the main switch and the burner switch. The burner is therefore activated and carries out the preventilation phase. If the air pressure exceeds the value at which the air pressure switch has been set, the ignition transformer activates and, subsequently, the gas valves activate as well. The safety valve opens completely whereas the main valve that incorporates the adjustment elements opens in two stages. The first opening stage carries out the trigger flow rate and occurs instantaneously. The second opening stage occurs gradually and at the end of it, the burner is at the maximum flow rate permitted by the position set on the maximum flow rate regulator. On first switching on, repeated lock outs may occur due to: -- The gas piping not being vented of the air sufficiently, so that the gas flow is insufficient to ensure a stable flame. -- The lock out with flame present may be caused by flame instability, due to an incorrect air/gas ratio. This can be solved by changing the amount of air and/or gas supplied, so as to find the right ratio. This problem may also be caused by a wrong air/gas distribution in the combustion head. This can be solved using the combustion head adjusting device by further closing (loosening the adjusting screw) or opening (tightening the adjusting screw) the air flow between combustion head and gas diffuser. To adjust it, use the flame disk adjusting screw. With the burner running, adjust delivery to the value corresponding to the desired capacity (methane = 8550 kcal/m 3 ) by reading the meter. This flow rate can be changed using the regulator incorporated in the valve, as described above. Make sure that combustion is carried out correctly by means of the relative instruments. Maximum carbon oxide (CO) allowed = 0.1 % with carbon dioxide value (CO 2 ) ranging from 8 to 10%. After this adjustment, switch off the burner and start it again for a few times to check if ignition is correct. SAFETY CHECKS After adjustment, always check that: the burner stops "opening" thermostats and air and gas pressure switches. a "lock out occurs when obscuring the photocell (UV). To unlock, push the appropriate button. MAINTENANCE At the end of the heating season, it is good practice to clean the gas and diesel fuel filters, the combustion head (disk, insulators, nozzles), the combustion air passages and the photocell (UV). It is advisable to use wooden or plastic tools to clean nozzle passages. Nozzles should be replaced after 12 months use. UV PHOTOCELL Even the slightest greasiness will compromise the passage of the ultraviolet rays through the UV photocell bulb, thus preventing the sensitive internal element from receiving the quantity of radiation necessary for it to work properly. If the bulb is fouled with diesel fuel, fuel oil, etc., it must be properly cleaned. It should be pointed out that even by simply touching the bulb with fingers, it is possible to leave a slight greasiness which could compromise UV photocell operation. The UV photocell does not see daylight nor does it perceive the light of an ordinary lamp. Sensitivity can be checked with a flame (cigarette lighter, candle) or with the electric discharge between the electrodes of a common ignition transformer. To ensure proper operation, the UV cell current value should be sufficiently stable and should not drop below the minimum value required by the specific equipment; this value is indicated in the wiring diagram. It may be necessary to search for the best position by sliding (axial or rotational movement) the casing that contains the ENGLISH 9 / 18

12 ENGLISH photocell with respect to the fastening clamp. This can be checked by connecting a micro-ammeter, with a suitable scale, in series to one of the two UV photocell connection cables. Obviously the polarity (+ and -) must be respected. SPECIFICATIONS FOR PROPANE USE We wish to inform you of a number of considerations regarding the use of liquid propane gas (L.P.G.). Operating costs approximate assessment -- 1 m 3 of liquid gas in gaseous phase has a lower calorific power, of about 22,000 kcal. -- To obtain 1 m 3 of gas we need about 2 Kg or about 4 litres of liquid gas. This reveals that the use of liquid gas (L.P.G.) yields approximately the following equivalence: 22,000 kcal = 1 m 3 (in gaseous phase) = 2 kg of L.P.G. (liquid) = 4 l L.P.G. (liquid) from which the operating cost can be assessed. L.P.G. has a greater calorific value than natural gas, which means that to burn completely, L.P.G. requires higher quantities of combustion air. S a f e t y p r o v i s i o n s Liquefied petroleum gas (L.P.G.) in the gaseous phase has a greater specific weight than air (specific weight relative to air = 1.56 for propane), which means it does not disperse in air like natural gas, which has a lower specific weight than air (specific weight of natural gas relative to air = 0.60), but precipitates and spreads out at ground level (as if it were a liquid). In view of the above principle, the Italian Ministry of the Interior has set limitations to the use of liquid gas in a specific regulation. The most important concepts are listed below. If the burner is installed abroad, comply with the regulations currently in force in that country. -- Liquefied petroleum gas (L.P.G.) burners and/or boilers may be used only in premises located above ground level and certified toward free spaces. Installations using liquid gas are not allowed in underground or semi-underground premises. -- Premises where liquid gas is used must have ventilation openings which cannot be closed on their outside walls with a surface area measuring at least 1/15 of the surface area of the room, with a minimum of 0.5 m At least one third of the total opening ventilation surface area must be in the lower part of the outside wall, flush with the floor. Measures to be taken for liquid gas system to ensure correct, safe operation. Natural gasification, from a cylinder bank or tank, can be used only for systems having low power. Gas supply capacity on the basis of tank size and minimum outdoor temperature are shown in the table below, as an approximate indication only. B u r n e r The burner must be ordered specifically for use with liquid gas (L.P.G.) so that it is equipped with gas valves of sufficient dimensions to ensure correct ignition and gradual adjustment. The valve sizing is foreseen for a supply pressure of approximately 300 mm W.C. You are recommended to check the burner gas pressure using a water column manometer. Controlling combustion To limit consumption and avoid serious trouble, adjust combustion using the appropriate instruments. It is absolutely essential to check that the percentage of carbon monoxide (CO) does not exceed the maximum permitted value of 0,1 % (use a combustion analyser or other similar instrument). The warranty does not cover burners burning liquid gas (L.P.G.) in installations in which these measures have not been taken. 10 / 18

18 ENGLISH The DUNGS MB-DLE... gas valve unit is made up of: A safety valve which closes and opens rapidly (6). A main valve which opens in two stages (5). The first opening stage occurs rapidly (release) and can be adjusted unscrewing the knob (2) and inserting it overturned on the underlying adjusting pin. The + and - symbols on the valve head indicate the direction in which the knob should be turned to increase or decrease ignition output (first valve opening stage). Rotating in a clockwise direction, the initial delivery (ignition flame) can be reduced; rotating in an anti-clockwise direction, the initial delivery is increased. The complete stroke from zero to the maximum is slightly more than three turns (40% of the total opening), and viceversa. When the first opening stage has taken place, the valve continues to open slowly and takes 15 seconds to reach the maximum open position. To adjust the desired maximum delivery, loosen the locking screw (4) (the one with protruding head and not locked with paint seal) and turn knob (3). Turn in a clockwise direction to reduce delivery and in anti-clockwise direction to increase it. It should be pointed out that when the adjusting knob is turned, the end of stroke which limits valve opening moves; therefore, when the adjusting knob is completely turned to the - sign, the valve does not open and the burner does not ignite. To get ignition, it is necessary to turn the knob in an anti-clockwise direction towards the + sign. The complete stroke from zero to the maximum and vice versa is nearly six complete turns of the knob. This adjusting operation (for maximum and ignition output) must be carried out without forcing the corresponding end of stroke. The pressure stabiliser (10) can be adjusted (see table) using the screw which can be accessed sliding the cover (1) to one side. The complete stroke from the minimum to the maximum to the position and vice versa is about 80 turns. Do not force the end of stroke. Around the access opening there are arrows with symbols indicating the sense of rotation for pressure pressure (clockwise) or decrease (anti-clockwise). This stabiliser hermetically closes upstream and downstream when there is no flow. Different springs to obtain different pressure value from those described above are not foreseen. To adjust the pressure stabiliser, connect a water manometer to the rubber tube holder installed on the fitting (8) corresponding with stabiliser outlet. The inlet filter (12) can be accessed for cleaning removing one of the two side closing plates. Minimum pressure switch (14). To adjust, it remove the transparent cover and operate the black knob. The reference mark is a small rectangle on the yellow disk around which the adjusting knob rotates. At the inlet, a fitting (13) has been installed on the connection flange to measure the inlet pressure. At the connection flange outlet, there is also a fitting (7) to measure the outlet pressure. The side pressure fittings (9), indicated as Pe, are in communication with the inlet pressure. The side pressure fittings (8) indicated as Pa, are used to measure the pressure coming out of the stabiliser. It might be useful to know that the pressure coming out of the valve unit (to be measured at fitting 7), corresponds to the pressure regulated by the stabiliser and is reduced by the necessary pressure in order to overcome the crossing resistance of the main valve (5). It should be pointed out that the valve crossing resistances vary based on valve opening regulated by knob 3 with which the end of stroke moves. To adjust the pressure stabiliser, connect a water manometer to the rubber tube holder installed on fitting (8) corresponding to the stabiliser outlet (Pa). The holes of the pressure stabilizer bleed (11) should be free and to ensure a proper operation. SUGGESTIONS FOR ADJUSTING THE GAS VALVE Connect the water manometer to the pressure fitting Pa (indicated as n 8) to measure the pressure coming out of the stabiliser. Put the gas delivery regulators for ignition (2) and for maximum delivery (3) in the position presumed necessary for the desired delivery. Also open the combustion air regulator. Switch on the burner. With the burner on, operate under the cover (1) on the the adjusting screw of the gas and pressure stabiliser regulator and adjust pressure to the value considered necessary to obtain the desired output, when the maximum output regulator (3) is in the maximum opening position. It should be pointed out that, normally, the above conditions require about mm.w.c. Put the ignition flow regulator (2) in the position considered necessary to obtain ignition with the minimum possible delivery.
