5 1 General information 1.1 Foreword Dear System Owner, you have made a good selection in the PYRTEC. It will provide you with all the advantages of a modern, economically efficient heating system. Fully developed technology in combination with a sturdy design guarantee a high degree of operational reliability and a long service life. These Operating and Maintenance Instructions contain important information for the intended use, correct operation and proper maintenance of the PYRTEC. Non-compliance with the Operating and Maintenance Instructions will result in loss of the guarantee. If you still need any further information after studying the Operating and Maintenance Instructions: The Assembly and Installation Instructions contain important information about: - Standards and regulations - Structural surroundings of the burner - Transport and assembly - Water installation and electrical installation - Fire protection - Starting up as well as an appendix with diagrams of connections and dimensions and the complete technical specifications. Our sales and services offices will be glad to provide you with any further information. Their addresses can be found on the reverse side of these Operating and Maintenance Instructions. 1.2 Technical standing The Operating and Maintenance Instructions are in keeping with the PYRTEC at the time it is delivered. In the interest of our customers, we reserve the right to make, without any notification requirement, subsequent changes resulting from further technology developments. 1.3 Intended use The intended use of the PYRTEC is for incinerating wood fuels. The intended use of the PYRTEC is stipulated: - in the regulations of the Assembly and Installation Instructions - by the limits of the technical specifications - in Spec Sheet 1010 "Minimum Requirements for Wood Fuels / Instructions", - by the safety regulations in these Operating and Maintenance Instructions. Any other use of the PYRTEC or use of it going beyond this will be considered as unintended use unless written approval by the manufacturer has been obtained. The following, among other things, will be considered as unintended use: - Operation of the PYRTEC by unqualified personnel, without any training or knowledge of the Operating and Maintenance Instructions. - Disabling the safety or monitoring devices on the PYRTEC. - Removal of any protective covers or cladding on the PYRTEC by unauthorised individuals. - Making any conversions or alterations to the PYRTEC without approval by the manufacturer. - Using spare parts or accessories from other manufacturers without approval by the manufacturer. The operating organisation will be liable for any damage or accidents in case of any unintended use. 1.4 Technical data The following important limits apply to the PYRTEC heating boiler: - Max. operating pressure allowed bar - Max. boiler temperature allowed C - Min. return temperature...65 C The complete technical specifications are listed in the appendix of the Assembly and Installation Instructions. 1.5 Information documented The Operating Instructions contain the information required according to the EC Directive on Machinery 98/37/EEC, Appendix 1, Number Issue: _English Prepared by: ShlM 1.6 CE- Symbol The PYRTEC is delivered with a CE-symbol on its type plate and an EC attestation of conformity in accordance with Appendix II A of the EC Directive on Machinery 98/37/EEC. If the PYRTEC is altered by equipment from other manufacturers being added, or the safety equipment or control system are combined with a different system and/or integrated into an overriding system (building control system, etc.), then in the European Union a new attestation of conformity has to be issued before it is put on the market. 5

6 2 Important information 2.1 Safety information When carrying out work on the heating system, such as cleaning and maintenance, wear appropriate protective equipping when required. There is a danger of getting injured through: burning, knocking against corners and edges, crushing in moving parts and noise. Mains supply 400V In dangerous situations, the PYRTEC can be disconnected from the electric mains for all the pins via the master switch on the control cabinet. Doors CAUTION FIRE HAZARD: The burner must never be operated with the doors open! Any burning bits that escape could start a fire. CAUTION DANGER OF INJURY: If the doors are opened during operation, sparks and tongues of fire could leap out. Equipment for dissipating excess heat The functioning of the thermal run-off safety valve must be inspected every year by a competent specialist. The safety heat exchanger must not under any circumstances be used as an operational heat exchanger. Seals For the functioning and controllability of the burner, it is important that no unwanted air can leak in, entering unchecked through leaky spots. The doors and lids have to shut tight any damaged seals must be replaced immediately. Tighten the retaining screws and handles snugly. Recirculating flue gas system: The recirculating flue gas system returns some of the emissions back into the combustion chamber under pressure. That is why the piping after the fan is designed to be pressure-tight. Before it is taken into operation, the recirculating flue gas system must be checked for leaks (no gas may escape when the recirculating fan is in operation and the flaps are closed). CAUTION RISK OF CO POISONING from escaping and perhaps odourless gas! Do not permit operation if the recirculating pipes are leaking! Operation, cleaning & maintenance Bear in mind that only if operated and maintained properly can even the best of products fulfil their functions well, for a long time and free of malfunctions. Compliance with the "Cleaning" section is mandatory! 2.2 Excess temperature & power failures I M P O R T A N T DANGER of this SUDDENLY GOING UP IN FLAMES! Do not open doors or lids on the burner! - Switch on additional heat consumers. - The exhaust fan goes out of operation. - The temperature-limiting safety switch triggers. - The valve for the thermal run-off safety valve opens at approx. 95 C. The excess heat is conducted off into the channel. If the temperature-limiting safety switch (TLSS) has triggered, then it has to be manually unlocked. The TLSS is situated at the top of the burner. To reset, unscrew the black cap and press the button. IMPORTANT: Only as of a temperature of approx. 70 C resetting is possible. Possible causes for excess temperature: - Sudden drop in output to zero. Do not turn off all the heat consumers at the same time. - Defective component of the system (pump or valve) - Incorrect setting on the control module. - "CYCLE, UNDERFEED AUGER, SUSTAIN EMBERS" too high (see the section "Load level" Output control system Sustain embers) 2.3 Lack of water & excess water pressure Possible causes: 1. Lack of water: Leakage in the heating system. 2. Excess water pressure: The expansion system not functioning. In either case, the facility should be left for a competent heating fitter to check. Unlock this malfunction with either the reset button for the water level control system or for the overpressure monitor, and by pressing the F1 key (Malfunction) on the control panel in the control cabinet door. 6

7 2.4 Fire hazard With underfeed firing systems, the conveying route creates a connection between the silo and the burning material in the burner. With the PYRTEC, the underfeed auger is also the metering auger, and is thus always filled up with material during operation. There are various safety devices provided to prevent burn-back. Temperature sensors: By means of temperature sensors on the underfeed auger, in case of excess temperature the loading to the underfeed auger is interrupted, and the underfeed auger's material is inserted into the combustion chamber. Slide valve (option): This closes in case of a standstill, danger of burnback or power failure (spring return motor). Rotary valve (option): Instead of a slide valve, in silos with pressurisation. Drop-off route: A vertical drop-off route interrupts the connected line of burning material. Fire-extinguishing system (option): This system, which functions independently of the electrical power, brings about a flooding of the material to be burned that is located in the underfeed auger. The activation temperature is approx. 95 C. 2.5 Minimum requirements for wood fuels The PYRTEC is only suitable for incinerating the fuels listed in Spec Sheet 1010 "Minimum Requirements for Wood Fuels" (see enclosure). If different fuels are used, KÖB will not assume any liability for the functioning or service life of the burner. Refer to the "Warranty" section in the General Terms and Conditions of Delivery. 2.6 Filling the fuel storage space Rotary sweep extraction and spring-operated extraction Switch off the facility using the function button on the control panel and wait until there is no more fuel in the feed auger. Fill the silo evenly to approx. 30 cm above the articulated arm or over the spring-mounted blades, switch on the facility using the function button on the control panel and wait until the articulated arms or the springmounted blades go under the cup washer. If any excess or negative pressure can develop in the silo when the filling is being carried out, at this point the facility has to be switched off again using the function button on the control panel. After doing so, finish filling the silo evenly and switch the facility back on using the function button on the control panel. Carry out refilling in the same manner. Pellet extraction auger Switch off the facility using the function button on the control panel and wait until there is no more fuel in the feed auger. Slowly and evenly fill the silo until the extraction auger is covered approx. 25 cm to 30 cm high over the entire open area. Level out any mounds that form from pouring. Switch on the facility using the function button on the control panel and wait until the metering container on the feed auger has filled. If any excess or negative pressure can develop in the silo when the filling is being carried out, at this point the facility has to be switched off again using the function button on the control panel. After doing so, finish filling the silo slowly and evenly. The facility can then be switched back on using the function button on the control panel. Carry out refilling in the same manner. 2.7 Correcting malfunctions of the feed systems The cause of motor malfunctions in feed systems is usually clogging by large pieces of wood or foreign matter. CAUTION DANGER OF INJURY: Always turn off the master switch before carrying out any repair of a malfunction on feed systems and every time before a maintenance lid is opened or a protective device is removed! Due to the facility's automatic operation, the point in time for the conveying means to be switched on is not foreseeable. 7

In such case there are no recirculated flue gas pipes (item 13). 8

9 4 Control system The control system for the Pyrtec furnace firing process (Pyrocontrol) is effected via a freely programmable SPS, which makes use of a visualisation system on a touch screen as the interface for navigation and parameterising. 4.1 Touch screen, Masks 1-8 The touch screen is 16 cm wide, 12 cm high and has a resolution of 640x480 pixels. The screen is a colour display monitor. After switching on the masterswitch, the SPS starts up, and the Overview appears (Mask 1) Navigation The navigation program "Pyrocontrol" is a product of KÖB Holzfeuerungen GmbH. It is operated following the same patterns as MS Windows programs. The selection of the softkey desired can be made with a fingertip or even more exactly with a fingernail. The arrangement of the softkeys is always the same throughout, i.e. once a keypad occurs, it is located at the same position in all the masks, with the exception of the BACK key (arrow in blue circle) in Masks 7 and 8. The hierarchy of Masks 1-7 (optional 8) ranges over the following levels: Mask 1 Overview Mask 2 Mask 3 Alarm List Change User Status Mask 4 Mask 7 Mask 8 (option) Settings Overview, Woodpowered Boiler Overview, Additional Boilers In Mask 1 you can choose between 7 or 8 different masks (8 being for an optional additional boiler). When choosing by tapping one of the two boiler softkeys (photo and optional symbol), either 7 "Overview of wood-powered boiler" or, optionally, 8 "Overview of additional boilers" appears (optional only with multipleboiler systems) in the mask title. All Masks 1-8 can be parameterised in detail by touching the respective softkeys provided. Doing so opens new windows in turn, and new input fields or softkeys are provided. 9

10 4.1.2 Mask 1 and how the mask is structured The following applies to all the masks. The mask title and user status are shown at the top. In the mask title you can tell which mask (1-8) you are in. In the centre of the mask the areas for display and call-up are always located for inputting parameters. The softkeys for navigation and input are located at the bottom, with the exception of the combined user status display and the call for input. Changeable softkeys for input are white (light). Display windows are always grey (dark). Softkeys for navigation are always provided in colour to select from. Area of mask Mask 1 Overview Description Top Centre Bottom Mask title, e.g. "Overview" User status (top right) Alarm line (bottom left, red) Date/Time (bottom right) Displays of operating mode of KÖB boiler (top left, grey), e.g. "OFF" (no heating operation) Display of actual value of boiler (grey): Exhaust gas temperature (top left), Residual O 2 (bottom left) Displays of buffer charge state (grey) Button for KÖB boiler (photo) With object indicator lamps (green/grey) Button for additional boilers (option) Sets of buttons, bottom right: Boiler ON (green) Boiler OFF (red) Lock screen (yellow) Sets of buttons, left bottom: Navigation (orange) for Masks 4, 5 & 6: Settings, Analysis, Archive Object indicator lamps, Mask 1: Boiler pump and display of operational status of additional boilers. If the object indicator lamp lights up green, then there is activity. Example: The pump is running and an additional boiler is in operation. If the object indicator lamp is grey, the respective object (pump or additional boiler) is shut down. Important: The object indicator lamp says nothing about the operating mode of the system. 10

11 4.1.3 Mask 2, Alarm List Touching the red Alarm line softkey (in Mask 1) opens Mask 2 (Alarm List with alarm logs, red). Here all the error messages are shown which have been registered but not yet acknowledged. Touching an alarm log line chosen allows the respective error message to be displayed in detail or acknowledged. A history of the error messages acknowledged can be called up in Mask 2. Area of mask Mask 2 Description Top Centre Mask title, e.g. "Alarm List" User status (top right) Alarm logs (red) in rows according to time Bottom Back button (back to Mask 1) Display alarm logs Acknowledge all The "Acknowledge all" softkey (bottom left) acknowledges the error messages listed in the centre of the mask. The cause of the error should be remedied before acknowledging the error message. Otherwise the error message will continue to be maintained. (It will be shown again in the Alarm List in a short period of time.) Touching the softkey "Display alarm log" (bottom right) will list all the past error messages. The softkey "Ascertain alarms in history" is displayed in the lower left of this new page. By touching this softkey, the period can be specified in which the alarms saved are to be displayed. 11

12 4.1.4 Mask 3, Managing the User Status Touching the softkey "Status Level 0", 1, 2 or 4 (at the top right of the mask), the user level can be changed and thus the access rights for parameterising stipulated. To change the user level, no user name need be entered, but rather all four possible levels are provided as buttons. When the user level desired (0-4) is selected, a password in the form of a 4-digit code will be asked for, which has to be entered and confirmed with ENTER by touching the white input cell using the pop-up number keypad. The password will then appear in four asterisks (****) and has to be confirmed again with OK. Area of mask Mask 3 Description Top Centre Mask title "User Status" Softkeys for selecting the user level desired Password query window: Always confirm with OK. Input number keypad: Enter the 4-digit code here and confirm with. Display: current level Bottom Back button (back to Mask 1) After making these entries, the newly selected status applies with the following user rights associated with it: User level Password Rights Standard Level 0 No password ( automatic jump back to standard after standstill period > 5 minutes). No rights, no changing (only display) Customer Level No selection of parameters with the trend display (Point 5.1) Customer Level Parameter selection is possible Administrator Level 4 No specification Administrator, access to WinCE Desktop as well as software updating possible By introducing these user levels, KÖB Holzfeuerungen GmbH is making an effort to maintain the parameters essential for quality-assured businesses. This guarantees good operational practice, as certain parameter changes are reserved only for KÖB technicians. This gives the user greater certainty that one cannot accidentally make any changes that would be technically less favourable. 12

13 4.1.5 Mask 4, Adjusting Settings & Process Parameters In Settings, adjustable categories can be chosen and their parameters changed. In the centre the parameters to be set are listed with their currently applicable values. Area of mask Top Mask 4, Settings Description Mask title "Settings > AutoBoilerCleaning" (left) User status (right) Centre Display Parameters set White fields can be changed by touching, provided a valid user status is set. Bottom Softkey categories (orange) The category activated is coloured yellow. Parameters can then be changed. Back button (back to Mask 1) If an attempt is made to change a parameter that is not cleared for change in the current user status, Mask 3 will be called up automatically. By changing the user status, here the authorisation required can be cleared (see Changing User Status 4.1.4). The value changes when the white "Setting input cell" is touched, which opens a pop-up number keypad. Enter the value desired and confirm with. The new value is immediately valid in the furnace-firing and/or heat recovery process. If the value selected is outside the setting range, then the maximum or minimum value possible will be automatically accepted. Factory setting (default setting) All the parameters in the Pyrocontrol, such as set point values and switching times, are already pre-set and can be produced in Mask 4 as "Set-point values". The values of the factory setting can be restored in User Level 2 or higher in the internal settings. 13

16 5 Commissioning, Operation & Shut-down 5.1 The initial start-up The initial start-up is carried out either by KÖB Holzfeuerungen GmbH or another competent individual named by it. Be absolutely sure to follow the instructions in the Assembly and Installation Instructions. No guarantee may be claimed for damages in cases of initial start-ups carried out improperly at one's own initiative Inspection before the initial start-up - Is there enough water in the heating system? - Has the heating system been bled of air? - Are the slide valves open for the heatingsystem's forward and reverse flow? - Can enough fresh air get into the heating room? - Are the doors and lids on the burner all closed leak-tight? The softkeys in Mask 1: Softkey 1 Softkey 2 Softkey 3 Switch on boiler When touched with the finger or fingernail, the colour changes (from light to dark) Switch off boiler When touched, a confirmation is requested, and then the colour changes (from light to dark).

17 5.2 Heating up without automatic ignition Filling the burner trough When the system has switched off properly, there is no more fuel in the burner trough or in the underfeed auger. With the fire block cooled down (fire box temperature below 250 C), touching softkey 1 "Boiler ON" will automatically fill the burner trough with fuel Heating up Light a fire with paper and kindling wood in the fire box. After this, use the blade to push the fire back to the filled burner trough. Then press Softkey 1 "Boiler ON" again (Softkey 1 "Boiler ON" is then dark green). Operating mode "HEAT UP" shows in the upper left of the display Fuel >W40 - With fuel that has water content greater than W 40 moist, preheat the boiler with a chopped wood fire. To do so, manually light chopped wood in the fire box and use the shovel to push it into the burner trough. If necessary, add more chopped wood. Heat up the fireclay brick lining like this for approx. one hour. - Starting up the facility: Softkey 1 "Boiler ON" The softkey "Underfeed ON" is for manually activating the underfeed auger in automatic operation (= manual prompt for material). As long as this softkey is touched, the underfeed auger moves fuel into the burner trough. With the underfeed auger stopped (softkey "Stop underfeed" lightgrey), the manual prompt for material cannot be activated Check of heat up successful? The fire box temperature should be over 180 C in 30 minutes (adjustable value). Otherwise the system will automatically shut itself back down. In such case press Softkey 1 "Boiler ON. 5.3 Heating up with automatic ignition The boiler is simple to switch on: - Press Softkey 1 "Boiler ON". The loader modules will be switched on in the appropriate order. When the auger filling time or fire box filling time has lapsed and there is enough fuel in the combustion chamber, the loader system switches off. - The automatic ignition then takes place. The ignition process stops as soon as the fire is started. - The boiler then automatically switches to full load operation. (If the material should be too moist, it might be necessary to proceed following Item "Heating up".) 5.4 Operation Full load operation As soon as a fire box temperature of approx. 180 C is reached (adjustable value), the system switches, depending on the boiler temperature, to operating mode "FULL LOAD" or "SUSTAIN", which is shown in the upper left of the display Output control The heat output to be produced is adapted to the heat consumption in a range from 25% to 100% of the boiler's nominal output. Depending on the deviation of the boiler temperature from the boiler set-point temperature (75 C to 95 C), the air flow rate is set by means of a fan with infinitely variable control. The fire box and residual oxygen control then resupplies the optimum amount of fuel for lowest emissions. If, through a corresponding rise in the boiler temperature, the heat consumption drops below 25% of the rated output, the system switches to "SUS- TAIN", which is shown in the upper left of the display Sustain In the operating mode "SUSTAIN", the exhaust fan only runs at a minimum speed. The supply air fans do not run. The resupplying of material via the underfeed auger has to be greater than the speed of back-burn and can be set as a set-point value by touching Softkey 4 "Settings" in Mask 4 (CYCLE for underfeed auger SUSTAIN). This depends on the material (light shavings require more resupplying of material than do chippings). "Cycle for underfeed auger sustain" too high: Too much material is pushed into the burner trough such that the embers are too large for the sustain load operation. The further consequence of this might bring about the malfunction back burn, excess temperature or overfilling of the fire box. "Cycle for underfeed auger sustain" too low: Too little material is pushed into the burner trough such that the embers are too small for the sustain load operation. This can bring about a back burn or the fire will go out Standby If too much heat is generated in sustain load operation, the control system automatically goes into standby operation. When this threshold value is reached, first the isolating valve shuts, and the auger module is slowly idled in the sustain mode. For the standby mode, all the drive activities (fans and auger modules) are stopped. Only then does "Standby" appear in the operating mode display. When the boiler temperature drops or a minimum standby period lapses, in the case of a prompt an automatic new start is carried out. 17

18 5.4.5 Transition in output To obtain a good structure of the fire and thus low emissions of harmful substances, the switchover from "SUSTAIN" to "FULL LOAD" is not carried out suddenly but rather gently Switching off Touching Softkey 2 "Boiler OFF" shuts down the furnace firing process properly. "Burn-out" is indicated on the display. The firing control system continues to run until there is no more fuel in the underfeed auger or the fire box temperature is below the set-point value and then it switches off. C A U T I O N: Do NOT use the masterswitch to switch off DANGER OF BACK BURN! 5.7 Operating modes The following terms are displayed in the operating mode line depending on the situation: Off Filling Auger filling Igniting Heating up The boiler is switched off. Cold start. The fire box trough is being filled by the underfeed auger. Direct or hot start with fire box still warm. The auger module is being filled. The ignition blower is running. The system is being started. The system is being slowly started. 5.5 Emergency operation The firing optimisation function can be switched off in Mask 7 by touching the "Emergency operation" softkey. If a sensory mechanism is defective, the switching off takes place automatically. Text shown on display: "SYSTEM PRESENTLY RUN- NING WITHOUT OPTIMISATION". The quantities of material and air are then manually set as setpoint values under "Emergency operation output" and "Emergency operation cycle of underfeed auger". The negative pressure is no longer corrected automatically. For this reason the fan settings must be checked. No positive pressure must develop in the burner. In case positive pressure should develop, adjust the mechanical means of throttling on the supply air fans. 5.6 Measurement operation It is possible to switch the boiler control system into "MEASUREMENT OPERATION" in Mask 7 by touching the softkey "Measurement operation" while the indicator in the upper left of the display is indicating "FULL LOAD". In "MEASUREMENT OPERATION" the output control is blocked to guarantee constant full load operation during the measurement. V E R Y I M P O R T A N T: In measurement operation the system does not switch to "SUSTAIN". Ensure heat consumption Danger of excess temperature! Full load Sustain Standby Auger idling Burn-out Emergency operation Measurement operation The boiler is running in regular operation. Embers being sustained. Boiler set-point temperature and the switching threshold "Sustain on" have been exceeded. The boiler temperature is over the switching threshold for standby and no prompt. The isolating valve moves shut, the boiler goes into standby. Example: After malfunctions or the boiler set-point temperature being exceeded. Upon a prompt for heat there will be an automatic new start. There is a malfunction or Softkey 2 "Boiler OFF" has been touched. The fire box is cooling down. Non-optimised operation with adjustable operational set-point values. Example: If a sensory mechanism necessary for optimised operation is defective, the switchover is being carried out automatically. Required sensory mechanisms: lambda-sensor, fire box temperature sensor & negative pressure measuring system. The output control is blocked to guarantee constant full load operation during the measurement. 18

19 6 Cleaning/Maintenance 6.1 Boiler Regular cleaning and maintenance of the facility is the customer's most important job for years of trouble-free operation and to obtain the greatest possible output with the best efficiency. Here the cleaning intervals for chip material are listed as per ÖNORM M 7133 with clinging bark 0.8% ash content. The cleaning intervals may vary, depending on the fuel, the amount of fine matter and the operating method. CAUTION RISK OF INJURY: Before beginning cleaning work, put the facility out of operation. Be absolutely sure to wear protective gloves, protective eyewear if required and use the cleaning utensils that come with the facility (danger of blow-ups, burns and getting crushed)! After each manual cleaning of the heat exchanger: Use kindling utensils to draw ash to the front and remove. With pneumatic pipe cleaning system, after approx. 600 operating hours; without pneumatic pipe cleaning system, after approx. 300 operating hours: Open boiler door and clean all the heat exchanger pipes with wire cleaning brush. IMPORTANT: With pneumatic pipe-cleaning system, disconnect the compressed air line before opening the boiler door danger of injury! After each manual cleaning of the heat exchanger: Open lid on both sides and remove ash.

CAUTION DANGER OF INJURY Turn off master switch 6.2 Feed systems All the geared motors on the feed systems are maintenance-free. - A change of lubricant and/or oil is recommended every 20,000 operating hours or every three years. - Re-lubricate flange bearings and other lubricating points regularly with lithium soap grease. - Check chain drives for wear and, if necessary, tighten them up and lubricate with chain oil. - Check all the bolts to be sure they are snug. - Once a year check the extraction components in the silo and/or bunker for damage and soiling. Remove any foreign matter there might be. - Check and lubricate rotary sweep extraction (AG), elbow joints, pivot pins, tension springs and tension chains; readjust elbow joints if necessary. - Inclined extraction system (AP / APS) Lubricate the gasket between the extraction casing and the geared motor and universal joint for the auger. IMPORTANT: Never use inflammable lubricants! Approx. every 4000 operating hours Clean secondary airflow fan. CAUTION DANGER OF INJURY Turn off master switch Approx. every 4000 operating hours Clean recirculated flue gas line WARNING INFORMATION: A mixture of emissions and air that may contain carbon monoxide (CO) and other toxic odourless gases is produced inside the recirculating flue gas piping system. Its pressure is slightly above atmospheric. Therefore the correct assembly of the cleaning lids must be checked and the system must be checked for leaks each time the system has been cleaned (when the recirculating flue gas fan is in operation and the flaps are closed, no gas may escape). After around 1800 operating hours (annually): Checks for leaks must be repeated each year so that any possible wear on the seals, particularly in the area of the maintenance covers, may be recognized and corrected in time. 21

22 7 Shutdowns Heating boiler Pipe-type heat exchanger When the PYRTEC is put out of operation for a long period (such as for summer breaks), be sure to carefully clean the pipe-type heat exchanger with a steel brush as required. Prevent high-temperature corrosion when chipboards are incinerated: If the heating room is moist or there is any other atmosphere that promotes corrosion (e.g. poor ventilation, residual enamel near the heating room, etc.), after carrying out the cleaning, also spray the pipe-type heat exchanger with biodiesel. If there is a danger of frost, empty the heating system, following the heating fitter's rules, or have anti-frost agent filled. Control system Even when the PYRTEC is put out of operation for long periods, the power supply to the control system should not be interrupted (do not turn off master switch). Why? - Avoid the formation of condensation in the lambda sensor. - Extend the service life of the buffer battery. 8 Waste disposal Shutdowns If necessary, first switch off the PYRTEC using the F2 key "ON/OFF". When the burn-out has taken place, and the burner has cooled off, turn off the master switch. Disconnect the mains connection to the control cabinet. CAUTION: DANGEROUS VOLTAGE! Only licensed electrical firms are allowed to disconnect and dismantle the connection to the electrical network. Close the forward flow and return flow slide valves. - Open the drain tap on the bottom of the boiler of the PYRTEC and drain water. Only heating system fitters may drain the boiler and dismantle the connections to the heating system. Disconnect the forward flow pipe and return flow pipe from the PYRTEC. Instructions for transport to a different location The personnel who carry out transports to different locations have to know the dangers involved of accidents that might arise in doing so and use suitable measures to prevent such from happening. Instructions for waste disposal Comply with laws and regulations of the land on disposing waste. Contract a disposal firm to dispose of and recycle waste in an environmentally friendly fashion. 22

23 Spec Sheet Wood Fuels Minimum Requirements / Information 1010/d _E A prerequisite for approval is the express permission for such by the public authority responsible. For claims to the warranty according to Section 11 of our General Terms and Conditions of Delivery, wood fuels have to meet the following conditions. If those conditions are not met, then approval is possible with restrictions (warranty, maintenance, operational safety) with a written statement by the manufacturer in reference to the facility. 1) Non-combustible substances contained No wood fuels may contain any foreign bodies, such as pieces of metal, stones, masonry remnants or plastics. Nor must the following limits (per kg of dry fuel) for non-combustible substances contained (ash analysed at a temperature of 815 C) be exceeded or fallen short of: Limit Comparison with untreated forest wood 1.1) Chlorine Cl: max. 300 mg/kg 10 mg/kg 1.2) Sulphur S: max mg/kg 120 mg/kg 1.3) Total Cl, S: max mg/kg 130 mg/kg 1.4) Ash content, total: max g/kg 5.0 g/kg 1.5) Alkali oxides in the ash (K 2 O and Na 2 O): max. 1.0 g/kg 0.35 g/kg 1.6) Sintering point of the ash: min C approx C Consequence of substantial overstepping of limits (1.1, 1.2, 1.3, 1.5, 1.6): a) Hot-gas corrosion in the heat exchanger Special maintenance instructions for heat exchanger Shortened service life of heat exchanger b) Early sintering and melting of the ash Special maintenance instructions for firing, Increased maintenance costs (firing, boiler door) If the maintenance instructions are not followed, a process will be created that builds up in a negative fashion with: Cinders change the airflow Temperature peaks more slag etc, until there is fast destruction of the refractory materials 1.7) Additives in remnant and used wood: Free of heavy metals and halogen compounds 2) Superfines & dust (wood particles smaller than 1.0 mm as per ÖNORM M 7133) 2.1) Without pre-dryer, max. 10.0% of the total mass; consequence of substantial overstepping of limit: Temperature peaks Slag formation Even higher temperature etc, to the point of destruction; Special maintenance instructions for firing; Elevated values are especially critical for remnant wood in combination with elevated values as per 1.1, ) For forest wood chips with pre-dryer, max 4.0% of the total mass; consequence of substantial overstepping of limit: Moving the exhaust air lines Special maintenance instructions for cleaning exhaust air line 3) Origin and treatment 3.1) Forest wood and plantation wood (complete trees and trunk wood untreated) Mature wood from trunks and branches, untreated, chopped as billet wood or chips 3.2) Compressed wood, pellets (conforming to standards, such as: ÖNORM M 7135) Untreated wood with limited bark content, compressed by machine and calibrated 3.2) Increased proportion of bark, tree cuttings from roadside trees (untreated) Remnants from the forestry and sawmill industries or from conservation of the countryside (elevated ash content). 3.3) Remnants from derived timber products Usually a mixture of untreated and treated wood in the form of shavings from processing machinery and chips from choppers that run slowly.

With a pre-dryer installed between the furnace and the fuel storage site, extra water content can be in the fuel stored (see specifications in reference to the order). The water content influences the maximum furnace output possible, the heat emission required to the pre-dryer and thus the maximum heat emission possible to the consumers. 7) Other information 7.1) Ash and cleaning Untreated wood without bark has a proportion of ash less than 0.5% of the fuel mass supplied. All the specifications regarding cleaning involved are based on untreated wood with bark attached with an ash amount of 0.8%. The cleaning and maintenance involved for other wood fuels should be adapted according to the amount, the specific weight and the behaviour of the ash. 7.2) Changing fuels A great change in fuel quality, such as bulk density, water content, dust proportion or ash content might make a manual correction of the firing parameters necessary (see Operating Manual). 8) Non-woody fuels from biomass Non-woody fuels from biomass, such as needles, foliage, grain, straw, fruit pits, etc, are usually unsuited as fuel for trouble-free operation and thus are not approved. 9) Wood fuels: rules, regulations and standards Germany: 1 st BImSchV 1 dated 14 Mar 97, amended on 2 Aug 2001; page: Fuels nos. 5 to 7 Austria: FAV dated 18 Nov 1997 "Feuerungsanlagenverordnung" (Furnaces Act 3.(1) 3.
