Its sturdy heat-resistant cast iron components ensure a long service life and minimise maintenance costs. Detailed technical data are presented on page 3. To make use of all features of the burner, it is important to observe these instructions. IMPORTANT Keep this manual in a safe place for future reference. Read this manual carefully before starting to use your BeQuem 50 pellet burner. The output of the pellet burner depends on how much pellets can be fed into and burned in the combustion head during one hour. (This means burning of pellets of the usual kind, which approximately comply with the fuel specifications described in this manual). NOTE! The protective hood on top of the burner must not be removed, unless the device has been disconnected from electricity supply. Follow the recommendations for the use and maintenance of the burner contained in this manual. SHIPMENT, STORAGE AND UNPACKING Delivery The manufacturer has insured the burner in case of damages during transport from the factory to the first interim storage location. Upon delivery it is important to check the condition of the burner before the burner is taken into use. If any damage is found, the seller shall be notified thereof without delay for possible claims. Storage The burner can be stored outdoors protected from rain for a short period of time. However, it is advisable to store the burner indoors. Disposal of the package The transport cardboard box can be recycled. FUNCTIONAL DESCRIPTION Heating with the BeQuem 50 pellet burner resembles in many ways oil heating. The greatest difference is that when heated with solid fuel a certain amount of ash is produced, which must be removed periodically. Otherwise, the efficiency of the burner will be reduced.

OPERATING PRINCIPLE SAFETY AND ALARMS The BeQuem pellet burner is provided with automatic ignition, but it can be ignited manually, when necessary. The electric ignition system of the burner will only be activated in case the temperature of the boiler has dropped at least 8 C below the target temperature. During heating, the necessary ignition cycles take place by means of embers in the combustion head, saving electric energy. The burner and the incorporated feeding system operate automatically. The operation of the burner is controlled by a temperature sensor installed in the burner. The combustion head of the burner contains an accurately defined mixture of fuel and air, which ensures perfect combustion cost-effectively and environmentally friendly. The burner auger is over-pressurized during operation. The purpose of this is to reduce the risk of damage to the burner, e.g. if the draft through the burner is weak. Wooden pellets with a diameter of 8 millimetres are the recommended fuel for the burner. COMPATIBILITY OF THE BURNER AND THE BOILER The pellet burner can be installed in boilers, which meet certain requirements as regards the size of furnace, sufficient under-pressure and ash space. Required furnace size: Depth at least 430 mm measured form the insertion opening. Free height above the combustion head at least 350 mm to guarantee a sufficiently large combustion space for the flame. The boiler must have a sufficiently large ash space under the combustion head so that the ash removal interval is sufficiently long from the maintenance point of view and to ensure good operational reliability of the burner. Ash removal should be performed through a separate hatch to avoid the need to remove the burner for this task. For safety reasons the pellet heating centre and the fuel storage must be placed apart from each other to prevent possible accidents: any operation disturbances and damages caused by incorrect handling of the device will then be limited to the burner. The fuel storage must be built as a separate, fire-classified, confined space. Problems caused by faulty stopping of the system are indicated by a red light on the control panel. In addition, a text message appears on the display indicating what has caused the alarm. During every operating cycle, a small amount of pellets (approx. 150 g) is fed from the pellet storage via the external feeding system to the upper connection of the burner. To make it possible to dose an accurate and same amount of pellets during every cycle, the dosing is carried out by means of a separate dosing auger via the blocking feeder and burner auger to the combustion head. Because the burner auger feeds pellets forward three times faster compared with the speed at which pellets arrive at the auger, a safety zone is formed between the combustion head and the upper connection containing only single pellets. Even if a mains outage would occur in the system, the equipment had not been maintained correctly, or some of the parts of the equipment would have broken down, this safety zone will remain intact. Supply control auger Top feed connection Air lock Primary air tube Ingnitor tube In the furnace there must be a sufficient under-pressure, ( natural draft ), which allows burning of the pellets efficiently. As a guide value approx. 30 Pascal is suitable. Burner auger Fan ARITERM SWEDEN AB Installation, Operation & Maintenance - 2009.02.18-4/20
INSTALLATION Good planning saves time. Ensure immediately upon delivery from Ariterm that everything is included and undamaged. If possible plan in advance for on-site assembly. Any required adaptation of the complete docking plate is easier to do on site (home) than in a workshop. The boiler must use natural ventilation and have ample space above the combustion chamber or at least 300 mm. Exeption is possible in a number of boilers, but often in combination with a marginal reduction in efficiency. Always contact us for advice when unable to achieve the recommended measurements. The door opening must be at least 230 mm high and 225mm wide. The chimney must always be inspected at installation for airtightness, draught and risk of condensation. Draught regulators and insert tubes may need to be instaled. The recommended draught is 30 Pa. Boilers should always be installed so that variations in draught conditions do not affect boiler performance. This can be accomplished with devices such as installing a draught regulator. Space needed for installation: The open space in front of the boiler (including burner) must be at least 1,0 m, in order to facilitate usage and burner servicing. Any condensation should be checked by visual inspection of the chimney s upper reach during various weather conditions. In the event condensation runs through the flue, a condensation vessel should be installed in the lower part of the chimney in order to tap off the condensation water. Do not cover the combustion air intake. ELECTRICAL INSTALLATION The supply cable delivered with burner is connected to the burner. In addition, an over-temperature protection thermostat must be installed in the boiler (this must acquired separately). The connection is made in accordance with the wiring diagram annexed to this manual. Also the use of a safety switch (burner switch) is recommended. The other connection cable delivered with the burner is for boiler temperature and flue gas sensors. Work on the burner may only be carried out by a qualified serviceman. Make sure to cut the power supply to the burner before servicing. COMMISSIONING Before starting up the boiler, check the following: The heating pipework and the boiler are filled with water and the pressure is at least 0.5 bar. The possible flue gas damper has been opened The recirculation damper in the convection part of the boiler is in place The circulation pump is running The valves in the heating pipework have been opened The combustion air opening has been opened The safety valve is connected without obstructions to the boiler and is in good operational condition.

The fully assembled mounting plate and service rail. 1 Mount the secondary air tube, service rail and quick-release hand hold as shown in the photograph. 2 Electric cables should be installed such that they must be disconnected before the burne can be withdrawn from the boiler. Use the door frame as a template for drilling the four holes for the boiler s stud bolts in the docking plate. In some cases, the docking plate s outer dimension must be adapted to fit the boiler. It is easiest to use a circular saw. Mount the plate against the boiler frame with heat-resistence glass fibre reinforced sealing strip or furnace cement, which can easily be applied afterwards through the mounting plate opening. Tighten while making sure the plate is not deformed. Final tightening of the service rail is to be done only once the burner has been attached and secured to the mounting plate. The service rail is to be pressed up against the boilers guide pins and outer clamping bolts are to be securely tightened. Check that the burner is centred on the mounting plate s guide pins when it is pulled out and pushed in. It is a good idea to lubricate the guide arms.

START-UP IN OFF MODE START-UP IN OPERATING MODE Cold start of the burner (with electric ignition) Cold start of the burner takes place after the burner has been switched off at the control panel, a fault has occurred in the operation of the burner, or the mains voltage returns after a mains outage. The temperature of the boiler must be at least 8 C below the set value. Otherwise, the automatic control unit supposes that the burner is in the hot start mode and does not use the ignition resistor at all. If the external feeding system is empty of pellets, it must be refilled before switching on the burner. Switch on the control unit of the burner at the main switch so that the red light turns on. Press the arrow button to the right. The operation display of the burner must be OFF. Browse menu 1 by means of the arrow button forward, until the message AUGER EXTERNAL MANUAL OFF is displayed. Switch on the external auger by pressing the Plus button. When the auger is rotating, the remaining running time is indicated on the display. The external auger can be stopped before the set time elapses by pressing the Minus button before the drop tube begins to be filled with pellets. To switch on the burner, go forward to menu 1 by means of the arrow button, until OFF (+ON) appears on the display. Select ON by means of the Plus button. Then the burner motors starts, the burner gets fuel to be fed to the combustion head via the feed auger, and after 3 minutes also the fan and ignition resistor will be switched on. The optical sensor of the burner detects the moment when fuel has been ignited and switches off the ignition resistor. At the same time, the operation light turns green and the speed of the fan decreases. Feeding of fuel stops completely within three minutes in order to give time for the fuel to ignite in the combustion head. After this pellets are fed at low power for further five minutes. After a full stop lasting ten minutes (7 starts), the operation program switches on and controls the burner functions. Only until at this point the burner switches to the normal heating mode. In case the ignition fails, the red light will come on again and an alarm message appears on the display. Hot start and switching off A green light indicates that the burner is in operating mode. During operation, the temperature sensor of the boiler controls the start and stop functions of the burner. When the temperature of the boiler has dropped 5 C below the selected set value, the burner switches to medium power. If the temperature drops by further two degrees, the burner starts to operate at maximum power. The burner operates at maximum power, until the temperature has dropped four degrees below the set value, after which the burner starts to operate at medium power again. The red light indicates that the device has been switched off. (see Troubleshooting ). Switching off To switch off the burner, select the menu ON (OFF). Select OFF by means of the Minus button. When the burner is in OFF mode, a red light is illuminated on the control panel indicating that the power has been switched on. The maximum amount of cold start cycles is seven. The proceeding of these cycles can be followed on the display by selecting the menu option Operating mode. Don t make any adjustments on the burner or similar measures during the ignition cycle. Note! When the burner is switched on at the first time or, for some reason, it does not contain any pellets, a restart is sometimes required approx. after a 3 minutes running time.

SETTINGS CONTROL PANEL Adjusting combustion The boiler is delivered with factory settings, which in most cases are sufficient for proper, efficient combustion. The boiler s factory settings can be applied if negative pressure is 30 Pascal (Pa) in the flue. If combustion is poor anyway and the flue gases from the chimney are black or the ash is grainy, combustion can be adjusted to attain the desired end results. Adjustment is made with a flue gas analyser and should be carried out by a service technician authorised by Ariterm. Flue gas analysis shall be shown for carbon monoxide (CO) values under 200 ppm and excess air (O 2 ) 6-8%. The fan s air quantity and the feed percentage for the burner screw is adjusted in the following manner. The amount of pellets in the burner cup is set in the output menu by changing the percent figure for POWER HIGH AUGER and POWER LOW AUGER. The amount of air is set in the output menu by changing the percent figure for PO- WER HIGH FAN 1 and 2 and POWER LOW FAN 1 and 2.

TROUBLESHOOTING In case an alarm becomes active, this is indicated on the display of the control panel with a red light and a text message. This facilitates troubleshooting, because the user can see the cause of the problem. The alarm is acknowledged by selecting OFF on the control unit. The cause of the alarm must always be determined and the problem removed before the device is switched on again. The following checks and remedies are described in such an order that the most probable cause of the problem is given first. Problem Check Remedy All display segments are out. The red operation indication is on. The display reads: ALARM PELLETS NO. The burner is requesting fuel, but has not received it. that the fuses of the control unit of the burner are intact and the main switch has been turned ON. has the over-temperature protection tripped? that there are pellets in the fuel storage. Replace the defective fuse in the control unit or turn ON the power by means of the main switch. Note! Disconnect the device from electricity supply before replacing the fuse. The size of fuses F1 and F2 is 4A/230 V. If the cause of over-heating cannot be determined with certainty, contact an authorised technician. If the over-temperature protection of the boiler has tripped, put it back into operation by pressing the RESET button. Also check that the 3-phase current is correctly connected. Add pellets. Problem Check Remedy The red operation indication is on and the display reads: CONTROL EL. IGNITION or CONTROL OPTICAL MONITOR The cause of the problem is that the optical flame monitoring of the burner has not detected flame during a certain period of time. No fuel has entered into the combustion head. that the motor shaft rotates the auger and the motor of the external auger operates. (In most cases the default setting of the operating time of the external auger (30 seconds) is not long enough to bring sufficient amount of pellets to the burner. If the problem cannot be removed by means of the above checks and remedies, the operating time of the external auger may be too short. In such cases increase the operating time (see page 15, menu 3 -> Auger external time ). However, the operating time must not be so long that pellets accumulate into the drop tube.) that the flame guard and/or the combustion head is not full of ash and the flame guard has not over-heated or sooty. If the motor does not rotate, disconnect the power cable from the boiler and connect it directly to a mains socket by means of the additional cable provided. If the motor has been over-heated due to a blockage or for some other reason, the over-temperature protection of the motor may have been tripped. The motor will not start until it has been cooled down. Also check that there are no blockages in the auger. If there are problems with the motor, contact an authorised technician. Remove ash, clean the combustion head from loose ash and wipe the flame guard clean. If the flame guard becomes easily sooty, the cause may be incorrect settings or too low underpressure in the furnace. In such cases call a technician. that the inclination of the drop pipe is not too gentle. that the inclination of the external auger is not too steep (max 45 ) or feeding of fuel has not stopped, because pellets have been stuck in the silo. Shake the drop tube and change the inclination so that pellets will not get stuck. Adjust the auger into a more gentle angle and turn it back and forth a few times so that the pellets come loose. The feed opening of fuel must be located in the middle of the fuel store (applies to small week stores). ARITERM SWEDEN AB Installation, Operation & Maintenance - 2009.02.18-13/20
TROUBLESHOOTING Problem Check Remedy Problem Check Remedy The device has been stopped during a hot start. The device has been stopped during a cold start. Check that the pellets fed into the combustion head are whole. The fuel consists of pieces, the burner cannot keep up the embers. The reason for recurring stops may also be an excessive play in the blocking feeder, which makes it difficult to keep up the embers. Check the function of the ignition resistor, unless ignition does not succeed after two start attempts. If the cause of the operation cannot be determined with certainty or the ignition resistor must be replaced, contact an authorised technician. that the feed auger, blocking feeder and burner auger rotate and are not blocked, e.g. because of a foreign object. A possible foreign object in the pellet fuel must be removed, if it gets stuck in the blocking feeder or in one of the feed augers. Remove the upper connection and take out the possible foreign object from the feed auger or blocking feeder. In connection with the inspection of the burner auger remove the four augers located between the inner and middle part and pull out the burner auger from the tube. Be sure to disconnect all cable connections. The red operation indication is on and the display reads: ALARM LEVEL MONITOR, or ALARM BLOCKAGE The cause of the problem is that the optical flame monitor of the burner has not detected light during a certain period of time. No fuel has entered into the combustion head. is there fuel in the upper connection? If there is no fuel in the upper connection of the burner, check the cable connections of the level switches. If this does not help, wipe the level switches clean. If the external feed of the burner does not start in spite of this or the level switches must be cleaned continuously, they may be defective and, when necessary, should be replaced by an authorised technician. ARITERM SWEDEN AB Installation, Operation & Maintenance - 2009.02.18-14/20
MAINTENANCE Burner Carry out the necessary inspection and maintenance measures described below in connection with cleaning of the boiler: Switch off the burner one hour before commencing maintenance of the boiler. The combustion head does not normally require any specific maintenance, but in connection with ash removal it must inspected and any accumulation of ash removed, as necessary. When installing the burner back in place, inspect the hatch seals for possible damage. Every 1 to 2 years Clean the primary air ring and the primary air tube inside from dust and lumps. Check the condition and tension of the chain. Adjust and replace all defective parts, as necessary. Lubricate the chain with low-viscosity oil. In connection with a new fuel delivery, the combustion head must be inspected in order to detect sintering (ash as well as stone- and gravel-like particles stuck together in the combustion head) in good time. Such particles must absolutely be removed from the combustion head at short intervals to prevent over-heating of and thus damage to the primary air ring. Sintering is often caused by impurities in the fuel and the fuel supplier shall be notified immediately of such problems. See also paragraph Advice about fuel pellets. Note! Handle ash always carefully, because it may still be glowing. Ash must be kept in a fire-resistant container. The use of any kind of solid fuel requires usually a little more care than in the case of oil heating, even if the burning would be automatically controlled, such as in BeQuem pellet burners. The need of maintenance may vary considerably. It is therefore advisable to inspect and clean the burner, boiler and its convection parts already after one week s operation. In this way the user gains experience to schedule the maintenance at correct intervals. These maintenance measures should be carried out at frequent intervals. Close the inlet of combustion air into the boiler room. Put out the fire using a fire extinguisher. Make a fire alarm, as necessary. ARITERM SWEDEN AB Installation, Operation & Maintenance - 2009.02.18-15/20
MAINTENANCE, CARE, SWEEPING Cleaning of Flame Control The burner cup and the screws within the cup must be carefully cleaned to ensure flawless operation. Pull the flame control sensor gently out of the pipe. Clean the flame control sensor. Check the condition of the chain and wheels regularly. Change worn out parts when necessary. Clean the flame controller metal pipe so that the ash in the pipe will not hinder the operation of the flame control sensor. The condition of the burner head wheels must be checked during maintenance. ARITERM SWEDEN AB Installation, Operation & Maintenance - 2009.02.18-16/20
ADVICE ABOUT FUEL PELLETS GUARANTEE / DISPOSAL Wooden pellets are renewable bio-energy fuel in a compact and uniform form, which is easy to handle. Moisture content is less than 10 %, which means that the pellets do not freeze or become mouldy. No chemical substances are used in the manufacturing process, but rather the binding agent is the tree s own lignin. Diameter of the pellet is 6 to 12 mm and length 10 to 30 mm. Due to the small size the pellets move freely in the feed augers. Most of the disturbances, which occur as a result of bad fuel quality, are caused by incorrect handling and interim storage before the product is delivered to the customer. Large contents of fine materials in the pellets may be caused by insufficient sifting. Sintering of ash is often caused by silicate impurities (sand). These things cannot be detected before burning. Note! If ash is sintered, sintered material must be continuously removed form the combustion head. Fuel storage The feeding system enables building the pellet storage for so-called bulk deliveries. The storage can be located either indoors or in a separate building outside the house. The shorter the transport distance from the storage to the burner is, the better the feeding operates. In designing the boiler room and the storage, the fire regulations must be taken into consideration. Actions in emergency situations Fire If the heating equipment catches fire, switch off the burner at a separate safety switch.
