PREFACE

The pellets-burning equipment IWABO Villa-s1x is designed for burning wood pellets after the equipment has been docked onto a heating boiler. The pellets-burning equipment IWABO Villa-s1x must not be fired with any other combustible materials. The pellets-burning equipment IWABO Villa-s1x is to be installed in a boiler room that has been approved for this purpose by the local authorities.

WARNING SYMBOL

This warning symbol will be shown in these operating instructions to make you aware of possible hazards if you do not follow the instructions.

There are two kinds of warning symbols and texts used in this manual:

WARNING warns you of dangerous situations if necessary measures are not being taken.

NOTE warns you of less than safe ways or procedures that might lead to safety hazards or material damage.

Iwabo Villa-s1x

SAFETY

· The plant must not be test-run or put into operation until it has been connected to a heating boiler and the smoke has a free passage out into the open air through a flue gas duct or chimney. The boiler's flue gas damper must not be closed because of the risk of blow-ups when the weather is changing. For this reason, a counter-draught valve should be installed to ensure even draught in the boiler and prevent burn-backs. The negative pressure in the boiler's fire chamber should be at least 0.05-0.06 Hpa (0.5-0.6 mm VP). · The chimney should be at least 125 mm in diameter and at least 6 m long. · The pellets must be kept in a moisture-free and ventilated storage. The plant is intended to be fired only with wood pellets 6 ­ 10 mm in diameter. NOTE Always wear mouth protection when handling pellets. · The boiler room where the pellets-burning equipment is installed must comply with the provisions stipulated by the local fire protection authorities. WARNING Only a qualified electrician is allowed to carry out the electrical installation work. · Modifications, changes or reconstruction of the pellets-burning equipment must not be carried out without the manufacturer's consent in writing. · spare parts that are not original spare parts and do not meet the manufacturer's specifications may affect the safety of the pelletsburning equipment and must, therefore, not be fitted without the manufacturer's consent in writing. · The pellets-burning equipment must not be installed in an environment where there might be a fire hazard. · Combustible material must not be kept in the vicinity of the plant. · No welding work may be carried out on the plant until the power supply has been cut off and the circuit board has been removed. · Do not open any hatch on the boiler during operation.

INSTALLATION

The boiler room where the equipment is located must comply with applicable fire-safety standards. Contact your local master sweep for approval of your boiler and chimney for pellets heating purposes and also of the location intended for the plant regarding the applicable fire-safety provisions. Contact your local building and environmental protection authorities to simplify the application/issuing of building permits for the installation. The equipment must be placed so that there is sufficient space to clean and sweep the burner, boiler and smoke duct. Before mounting the frame (A) onto a suitable boiler hatch, drill mounting holes through the frame and insert the counter-sunk screws supplied. If a swing-arm is to be used, this must be installed on the frame (A) before screwing the frame onto the boiler. Mount the burner so that it comes inside the water jacket of the boiler. The distance from the fire bed on the grate to any boiler surface should be 200-250 mm so that the flame has sufficient space and satisfactory combustion can take place. If the distance is not quite sufficient, a flame director can be ordered as an accessory. The flame director directs the flame forward. screw the burner onto the hatch frame with the thumb wheels (B) supplied. The connection between the burner and boiler must be tightly sealed so as to prevent unintended draughts or flue gas emissions. The burner is pre-set for 8 mm dia. pellets of good quality and about 1 kW (mm ca 9 kW) energy input at a feed auger inclination of degrees. After installing the feed auger in the pellets bin or storage, mount the feed hose so that it is slightly bent and see to it that the upper and lower hose connections are somewhat displaced from each other. Now you can fill pellets into the bin or storage. (For starting up the equipment, see the start-up instructions).

Iwabo Villa-s1x

Check whether there is a risk of condensation in the flue duct by measuring the flue gas temperature 1 m below the top of the chimney. If the temperature is less than 80° C in winter, there is a condensation risk. If the flue gas temperature is only a few degrees below 80° C, it may be sufficient to install a counter-draught hatch on the flue duct between boiler and chimney in the boiler room. If the flue gas temperature is below 75° C, an insert pipe should be installed throughout the length of the chimney.

NOTE

In order for the guarantee to be valid, a flue-gas analysing instrument must be used for adjusting the burner, and the enclosed installation report must be filled in correctly and sent to Naturenergi Iwabo AB. Adjustment with such an instrument is also required when changing pellets size or quality.

CONTROLS

Start: The unit is started by turning the On/Off switch for the boiler to 1 or On and turning up the boiler's double thermostat to the desired boiler temperature. Stop: Turn down the boiler thermostat. Emergency stop: Turn the boiler's On/Off switch to 0 or Off.

START-UP AND OPERATION

Feeding of pellets

Connect the plug of the feed auger to a wall socket. It takes about 10-20 minutes until the tube is filled up to its discharge opening (the time indicated applies to augers 1.5 m long and about 45¡ inclined.) When the pellets have reached the discharge opening, let the auger run for about 2 more minutes so as to properly fill the tube to obtain even feeding. let the pellets tumble into a bucket so you can easily put them back into the pellets storage. Now connect the auger plug to the socket on the burner and install the hose between the auger tube and the burner.

Whentheburn-downphaseiscompleted,theburnerisreadytoberestarted. If the first ignition attempt has failed: 1. The thermostat is still calling for heat. 2. The fan accelerates for 15 sec. 3. The fan slows down to 1500 rpm, and new ignition fuel is being fed in for 37.5 seconds (= 50 % of the first amount). If the photocell detects fire within 300 sec., the cycle continues in the normal way (see items 6, 7 etc. above). If even the second ignition attempt has failed: If no fire has been detected after the second ignition attempt lasting for 300 sec., the burner goes into burn-down mode according to the value set on P4, triggers an alarm via the yellow light diode lD2 (showing a steady light) and then stops. Before restarting the burner, the cause for the failed ignition attempts must be found by way of trouble-shooting. Zero the burner by cutting off its power supply for at least 5 sec., after which it can be restarted. If the photocell sees no more fire during the heating cycle: If the photocell sees no more flame for more than 30 seconds, the fan continues for 30 more seconds, after which the burner goes into normal burn-down mode according to the value adjusted on P4. When the burn-down phase is completed, the cycle starts anew, just like it does when the thermostat cuts in. If the burner is not ignited after this attempt, it triggers an alarm via the green light diode lD3 (showing a steady light). If the factory-set values need to be changed, follow the instructions provided in chapters "Adjustment of control electronics" and "Tuning of burner".

SETTINGS

Adjustment of burner: Even though the burner has been pre-set prior to delivery, it must be adjusted to the individual operating conditions (type of boiler, draught, pellets diameter etc.).

The fuel feeding times can be changed on the control circuit board to match the pellets diameter, desired output and auger inclination (max. 45°). The pre-set times can be found in the tables in chapter "Adjustment of control electronics" and on the inside of the burner's hood. When changing these times, note down the new times on a servicing record sheet we recommend you to keep.

Change of times, dampers etc. When changing operating conditions after the electrician has tuned the burner with flue gas instruments, a new analysis must be performed to ensure satisfactory combustion and optimum fuel efficiency. Factory setting of damper on the fan is 30mm open. Flue gas temperatures can be changed by longer or shorter fuel feeding intervals and an adaptation of the damper opening (increased feeding requires increased damper opening; decreased feeding requires decreased damper opening). Which flue gas temperature is needed, depends on the type of chimney the boiler is connected to. Brickwork chimneys require higher temperatures, as the temperature here usually drops by some 15-20° C per meter, while in a steel chimney it drops by about 5-10° C per meter. The temperature should be about 80º C one meter below the chimney's top. This prevents condensation and freezing damage in the chimney.

Reading of potentiometer values To be able to read the value at which a potentiometer is set, first the green light diode lD3 is flashing for a particular potentiometer, followed by a flashing of the yellow light diode lD2 for the value this potentiometer is set to. This happens continuously ­ Pot.1, 2, 3, 4, 5, 1, 2, ... ­ , no matter if the burner is in operating or resting mode. Example (see the table below): 3 green flashes followed by 6 yellow flashes means that the burn-down time is set so that the fan continues to run for 210 more sec. after the photocell has stopped seeing light WARNING Do not change any values during operation ­ beware of the high voltage on the circuit board!

TUNING OF BURNER

If the plant does not work satisfactorily: · Check pellets level. During operation, the holes on the grate should be covered with pellets. · If the pellets level in the burner is too high: Increase the air supply by opening the damper on the fan, or decrease the pellets infeed (with P2). · Check the flue gas temperature (is normally between 170 and 240° C). ­ If temperature is too high: Reduce pellets feeding with P2. ­ If temperature is too low: Increase air supply with the fan damper. · If the fuel level in the burner is too low: Check the flue gas temperature as described above, reduce the air supply or increase the pellets feed (P2). · The pellets feed rate is changed with P2 on the circuit board (increase clockwise or decrease counter-clockwise). Also check air damper and flue gas temperature. NOTE: In order for the guarantee to be valid and also to obtain optimum combustion, the burner must be set with a flue gas analysing instrument.

SAFETY SYSTEMS AGAINST BURN-BACK

The pellets burner is provided with two safety systems against burnback as well as a combustible feed hose of "self-extinguishing" quality. WARNING Only a self-extinguishing, combustible hose may be used. A CHUTE disconnects the pellets strand from the feed auger. The chute on the burner is approx. 250 mm long. The auger is connected to the burner via a combustible hose. As the burner does not have any internal pellets storage, there are no more pellets in the burner than those being burnt on the grate. A HEAT SENSOR on the connecting pipe: If the thermal protector on the connecting pipe senses heat (>90°C), the power to burner is cut off. If the thermal protector trips, it must be reset. This is done by first turning off any power supply and then unscrewing the fan hood and pressing the small reset button on the thermal protector. The fan hood must be screwed back on and the cause for the tripping of the thermal protector remedied before restart may take place. WARNING Cut off the power supply prior to any intervention on the heat sensor (230 V). The burner is also provided with a hatch-frame switch, which prevents the burner from starting when it is removed from the boiler for cleaning. A monitoring function for fan and feed auger is integrated in the circuit board.

MAINTENANCE

The pellets-burning equipment IWABO VIllA-s1x has been developed to require minimum maintenance. A major proportion of the effort required is directly dependent on the quality and size of the pellets used. When the chimney sweeper is going to sweep your plant, be sure to shut the plant down well ahead so that the burner will be able to cool down. WARNING Prior to any maintenance intervention, cut off the power supply to the plant. Cleaning/Ash handling: The residue from burning wood pellets is approx. 0.5 ­ 1% ash. The type of combustion chamber together with your particular kind of fuel and fuel consumption will soon give you an indication of how often the burner must be cleaned.

1

Iwabo Villa-s1x

The ash must be kept in a closed vessel. Clean the grate after approx. 400 litres pellets consumption or once a week. Depending on the pellets quality, this interval can be extended to once every other week. · Turn down the thermostat and let the fan run for approx. 4 more min. (after-burning time). · Cut off the power supply and leave the burner to cool so as to eliminate the risk of burn injuries. · Remove the thumb wheels and pull/fold the burner out of the boiler. If necessary, remove the connecting cables from the boiler. · Remove and clean the grate. · Remove ash from the burner and, if needed, from the boiler. · Remove cinders from the ignition hearth plate and clean the cavities. NOTE: When re-inserting the grate, its plane portion must be pushed in as far as possible under the ignition hearth plate.

Photocell

WARNING Safety gloves and safety goggles must be worn when removing cinders.

Clean the photocell as needed. Checking/cleaning the photocell: · Pull the photocell straight out. · Clean the photocell of soot, with moistened rag if needed. · Check the fitting ring position on the photocell. · Refit the photocell in the recess. NOTE: No welding work may be carried out on the plant before the power supply has been cut off and the circuit board has been removed.

MAINTENANCE SCHEDULE

1. 2-4 times a month: Remove ash and cinders. (Depending on pellets quality). 2. Once a month: Clean feed chute and drop pipe. 3. Once a month: Clean the boiler's flue ducts and convectors (more often for higher efficiency). 4 Once every quarter of a year: Clean out fines/sawdust from the pellets storage/bin. 5. Once a year: Check the burner setting with instruments (to be done by your dealer or electrical installer).

TROUBLE-SHOOTING

Plant has stopped: Before turning off the power supply when the plant has stopped, check what lD1, lD2 and lD3 are indicating. This will be of great help when trouble-shooting. · · · · Check whether there are pellets in the bin/storage. Check whether the feed auger works (feeds pellets through). Clean the grate. Restart.

Plant does not start: · Check the hatch-frame switch. · Check the boiler thermostat. · Check whether there is power supplied to the plant, also check the power cable plug connection. · Check the fuses in the fuse box. · shut down the power supply and push the reset button on the thermal protector. Then remount the fan hood and switch the power supply back on. Fan and ignition are working, but pellets are not fed through: · The thermal auger motor protector may have tripped. Disconnect the power supply and wait for approx. 10 min. Disconnect the power supply and ask a qualified person to check and, if necessary, replace the glass fuses (20x5 mm, see control electronics circuit board), for: - ignition coil 6.3 A (delayed-action fuse) - fan 800 mA (quick acting) - feed auger 1.0 A (quick-acting)

DESCRIPTION OF FUNCTION

Please take a few minutes to read this description carefully. WARNING High voltage on the circuit board! Once the burner is connected electrically, turn down the thermostat and turn the main power switch to On or 1. Now observe how the two light diodes at the top of the circuit board are flashing (the burner's limit switch must be pushed in). One light diode shows which potentiometer is being read and the other one which value this has been set to. Have a look at the inside of the hood (see also the chapter "Adjustment of control electronics" in this manual ). The table shows how many flashes correspond to a certain value. The most important value for the electrical installer is the cycle feeding (P2). This controls the effect fed into the burner: higher input ­ more flashes, lower input ­ fewer flashes.

Light-emitting diodes

The green light diode lD3 indicates the potentiometer for which the value will be shown. The yellow light diode lD2 emits the number of flashes corresponding to the value the potentiometer is set to. The red light diode lD1 is lit when the photocell detects light. This flashing goes on no matter if the burner is in operating or in resting mode. On the table inside the hood you can check the time set for each potentiometer.

CHECKS AFTER INSTALLATION

The flue gas temperature must be checked (is normally between 170 and 240 degrees). If the flue gas temperature is incorrect, adjustments must be made as described in this instructions manual. Flue gas analysis (for example with Testo 325M flue gas tester): Flue gas temperature: 170-240 degrees. If temperature is too high, there can be too much excess air; if temperature is too low, the boiler's turbulators (if any) must be checked (these can be removed or shortened if necessary). 10 - 12% 500 and lower 1.7 - 2.4. Preferably below 2 to obtain satisfactory fuel utilization and efficiency.

CO2 content: CO ppm: Excess air (-value):

O2 content: Efficiency in %: Negative pressure in the boiler:

8 - 11% 80 % and more (combustion efficiency)

0.15 - 0.2 Hpa (1.5 - 2 mm Vp) 0.05 ­ 0.06 Hpa (0.5 ­ 0.6 mm Vp)

to be measured at the boiler's flue connection; to be measured in the fire chamber.

Note: These values can be used as good starting values for plants with a new boiler. On older, leaky boilers, the excess air may exceed 3. Negative pressure in the fire chamber must be at least 0.05-0.06 Hpa. Tips: For checking the boiler's tightness you can use a flame. If a hatch is leaking, the flame will be sucked toward the boiler. If you have a leaky boiler and throttle the damper in order to obtain ideal values according to the table above, the photocell might get insufficient cooling and break down (melt). so if you have an older, leaky boiler, you should be prepared to make a few compromises.

ASSEMBLY OF IWABO 2.5M PELLETS FEED AUGER

4 1 Remove the plastic plate covering the motor section (drive section).

Pull the extension section off and turn it. Now push the drive section and the extension section together so that the recessed opening on the extension tube will be at the end of the auger. Push drive section tube and extension tube together until they "touch bottom". Turn the extension tube so that the recessed opening in the tube will be on the opposite side of (180 degrees from) the drive section tube outlet.

2

Remove the end plate from the tube without motor (the extension section).

5

Fasten the jointing sleeve with the two screws supplied to connect the drive section tube with the extension tube. Drill holes for the screws in the jointing sleeve and tubes. Connect to power source 220/230 V and testrun. Now the feed auger is ready to be taken into operation.

6 3 Remove the tape (or the like) keeping the drive section and extension section together and fold out the extension section. Be careful so as not to damage or stretch the feed auger inside.
