INSTRUCTIONS FOR CONNECTING, OPERATION, AND MAINTENANCE OF THE STOVE

Heating devices (in this manual they are called “stoves") by Gorenje d.d. (in this manual titled Gorenje) are assembled and tested in accordance with the safety and applicable measures, and regulations of the European Community.

This manual is intended for users of the stoves, contractors who install the stoves, operators and workers for stove maintenance that is shown on the front page of the manual.

If you do not understand something in this manual, please contact our professional services or an authorized service center. In doing so, always specify the number of the chapter where there is some ambiguity.

Printing, translation and reproduction, even in part, of this manual is subject to licensing by Gorenje, d.d., which means that Gorenje d.d. must approve these actions. Technical information, figures, and specifications in this manual must not be given to a third party.

WARNING:

IMPORTANT: Connecting the appliance to the electrical installation must be carried out by qualified and authorized persons in accordance with applicable regulations.

This appliance is not intended for use by persons (including children) with reduced physical, motor, and mental capabilities, or to persons with a limited knowledge and experience in the absence of the person responsible for their safety or care.

Children cannot be allowed to play with this appliance.

DOUBLE COMBUSTION SYSTEM

The flame obtained by proper combustion of the pellet in the stove emits the same amount of carbon dioxide (CO2), which would be freed as a result of the natural decay of wood.

The amount of carbon dioxide (CO2) obtained through combustion or decomposition of plant mass corresponds to the amount of carbon dioxide (CO2) which the plant mass is able to obtain from the environment and to transform it into air and carbon of the plants during its entire lifetime.

The use of non-renewable fossil fuels (coal, oil, gas), contrary to what happens with the wood, releases into the atmosphere huge amounts of carbon dioxide (CO2), that have been gathering up for millions of years, creating a greenhouse effect. The use of wood as fuel is therefore perfectly balanced with the environment, because the wood as a renewable fuel is in ecological harmony with nature.

Using the principle of clean combustion, we fully achieve these objectives, and so Gorenje, d.d. has directed its development and all activities towards fulfilling this goal.

What do we consider clean combustion and how does it work?

Controlling and adjusting the primary air and injecting the secondary air causes secondary combustion, or the so-called post-combustion, which provides a secondary flame that is by its nature lighter and stronger than the primary flame. The addition of a new oxygen (inserted through the air) allows further combustion

of gases that are not completely burned. This significantly increases the thermal efficiency and reduces harmful emissions of carbon monoxide (CO), because the incomplete combustion is minimized.

2. THE TASK PURPOSE OF THIS MANUAL

The purpose of the instructions is to enable the user to take all the necessary measures in order to ensure safe and proper use of the stove.

2.1 UPDATES

This manual reflects a work of art at the moment when the stove was placed on the market. Therefore, GORENJE does not take into account the stoves that are already on the market with the appropriate technical documentation and considers them as defective or inadequate after any kind of modification, adaptation or application of new technologies to newly produced machines.

The contents of this manual should be carefully read and studied. It is necessary to strictly follow all the instructions given in this manual. All information contained in this manual is necessary for proper connection, use, and maintenance of your stove.

Therefore, this manual has to be carefully stored for the necessary instructions in the event of any problems or concerns.


6

If the stove is given or sold to another person, the new owner must also be given this instructions manual.

If you have lost your manual, the manufacturer can provide you with a new one.

3. RESPONSIBILITIES OF THE MANUFACTURER

In issuing these instructions, GORENJE accepts no civil or legal liability, direct or indirect, due to:

Accidents caused by not respecting the standards and specifications given in this manual,

Accidents caused by improper handling or use of the stove by the user,

Accidents resulting from modifications and repairs, which were not approved by GORENJE,

Poor maintenance,

Unforeseen events,

Accidents resulting from the use of spare parts that were not original or not intended for these models of stoves.

Responsibility for connecting is fully assumed by the installer - contractor.

3.1 GENERAL CHARACTERISTICS OF USERS

The user of the appliance must have the following basic characteristics:

be an adult and responsible person,

have a specific technical knowledge that is needed for routine maintenance of electrical and mechanical components of the stove.

CHILNDREN ARE NOT ALLOWED NEAR THE STOVE OR TO PLAY WITH IT WHILE IT IS ON.

3.2 TRANSPORTING AND USING THE STOVE - HANDLING

When using the stove, it is necessary to be careful and not allow the stove to tilt forward. This is because the brunt of the stove is forward. During transportation of the stove, which has to be completely safe, make sure that the forklift has the load that is greater than the weight of the stove that it is supposed to lift. Avoid twitching and jerking movements. ALL PACKAGING SHOULD BE REMOVED SO THAT IT IS OUT OF REACH OF CHILDREN, BECAUSE THE MATERIALS THAT ARE INSIDE CAN LEAD TO CHILDREN SUFFOCATING. THESE INCLUDE PLASTIC BAGS, FILM, POLYSTYRENE, ETC.

3.3 RESPONSIBILITIES OF THE INSTALLER

Installer's responsibility is to do all the tests of the flue pipeline, air supply, and all the things that are necessary for connecting (installing) your stove. Installer's responsibility is to adjust the stove to local regulations which apply where the stove is connected (installed).

The use of the stove must be in accordance with the instructions for use and maintenance, as well as with all the security standards that are given by the local regulations that apply where the stove is connected (installed).

The installer has to check:


7

the type of stove to be connected,

whether the room corresponds to the stove where the stove will be installed, which is expressed as the minimum size required for installation, set forth by the manufacturer of the stove,

heat generator

manufacturer's instructions regarding the requirements of smoke removal systems (ducts and pipes for smoke exhaust),

inner cross section of the chimney, the material out of which the chimney is made, uniform cross section,

that there are no disturbances and obstacles in the chimney,

height and vertical extension of the chimney,

altitude at the place of connecting the stove,

the existence and suitability of the protective cover for the chimney that is resistant to the wind,

the possibility of securing the external air supply and the size of the necessary openings,

Simultaneous use of stove that needs to be connected with other equipment that already exists at that place.

If the results of all checks are positive, then we can proceed with connecting the stove. Make sure you follow the instructions of the manufacturer of the stove, as well as the standards for fire protection and the safety standards provided.

When you are finished connecting, the stove has to be turned on in trial mode for at least 30 minutes to test if the stove is working properly.

When the installation and important details are completed, the installer must provide the client the following:

Instructions for use and maintenance issued by the manufacturer of the stove (if such instructions are not provided with the stove),

The documentation necessary to comply with the existing standards.

4. INSTALLATION – STOVE INSTALLATION

Responsibility for the work carried out at the place of connection is entirely on the user.

Before one turns the stove on, the installer must meet all legal standards of safety, as well as the following requirements:

to check that setting up the stove complies with local, national, and European regulations,

that the location of setting up the stove meets the requirements set forth in this manual,

to set up the flue pipes,

that air intake matches the type of the installed stove,

that the electrical connections are not set up using temporary and/or not insulated electrical cables,

to evaluate the effectiveness of grounding electrical systems,

to always use personal protective equipment and all means of protection that are prescribed by local regulations,

to always provide sufficient service space required for any maintenance and repair of stoves

4.1 INSTALLING THE STOVE

We recommend you to unpack the stove only when the stove is set up in the position where it will be connected.


8

The stove is on the plastic pins that have M10 bolts (4 items), that are threaded into the stove base. At the screws there are M10mm threaded nuts to the plastic parts. The legs are wound up all the way to the base of the stove. After unpacking the stove, when you put it in a place where it will be located, it is necessary to unscrew all the legs, so that a total height from the floor to the base of the stove is about 25mm. When you are done with nivelation of the stove that needs to stand horizontally, tighten the nuts with a 17 wrench, which needs to approach the base of the furnace, and at the same time hand-holding the plastic part of the legs, tighten the nut. The height of about 25mm from the floor to the base is needed for better circulation of air and cooling the stove. In this way you protect the stove from overheating and you extend its life.

If the surrounding walls and/or floors are made of materials that are not resistant to heat, then one should

use adequate protection using the insulating material that does not burn.

Always make sure that you leave a safe distance (about 35/40 cm) between the stove and furniture, home appliances, etc. To protect the floor if it is made of combustible materials, we suggest you put a metal plate under the stove on the floor with the thickness of 3-4 mm that will stretch 30 cm in front of the stove.

The stove must be at least 25 cm away from the surrounding walls. Always leave at least 15 cm between the rear side of the stove and the wall to allow for proper air circulation, or for the air to flow properly in that area.

If the stove is installed in a kitchen with a trellis for drawing out air or if it is placed in the room with appliances that use solid fuel (such as a wood burning stove), always make sure that the amount of inlet air in the room is sufficient to ensure safe operation of the stove.

If a smoke channel goes through the ceiling, it should be properly thermally insulated using the protection out of insulating materials that does not burn. When the stove is set up into place, it should be levelled using pins.

DANGER !

The exhaust gas Armour must not be connected to:

- the smoke pipe used by another heat generator (boilers, furnaces, fireplaces, stoves, etc.),

- the air drawing system (grilles, ventilation openings, etc), even if the system is inserted into the drain pipe.


9

DANGER !

It is forbidden to install shut-off valves for the flow (draft) of air (flap valves that can prevent airflow or disable drafts).

ATTENTION

If the ejection path of smoke creates such a bad draft, of a bad flow of air (many curves, improper completion of the ejection of smoke, constriction, etc.) discharge of smoke can be bad, or in a situation like this smoke discharging is not as good as it could be.

The smoke ejection system from the stove operates under negative pressure in the stove chamber and with mild pressure from the smoke drain pipe. It is very important that the smoke extraction system is hermetically closed (sealed). This requires the use of a smooth tube on the inside. First of all you must carefully study the plan and structure of the room when the smoke extraction pipe is set up through the walls and roof, so that the installation of pipes is performed properly in accordance with the standards of fire protection.

You should first ensure that the room where the stove is located has enough air for combustion. It is advisable to periodically performs check so as to ensure that the combustion air comes right up to the combustion chamber. The stove operates at 230 V ~ 50 Hz. Make sure that the electrical cord is not underneath the furnace, to be away from the stove, to be away from hot spots, and not to touch any sharp edges that it could interdict. If the stove is electrically overloaded, this can lead to shortening of the lifetime of the electronics of the stove. Never turn off the power supply by pulling the plug when there is a burning flame in the stove. This could jeopardize the proper functioning of the stove.

4.2 THE SMOKE EXHAUST SYSTEM

The smoke exhaust must be carried out in accordance with existing standards. Exhaust gas tube should be well sealed (see Figures 1-7).

For smoke exhaustion, one can also use classic brick chimneys while flues can also be made of pipes that need to be well insulated (double wall) and sealed, to avoid creating condensation in them. The drain tube absolutely must not be connected to other systems of any kind, such as the systems where the smoke is removed from the combustion chamber, exhaust grilles or air distribution system, etc. Also, the smoke exhaust must not be set up in enclosed or semi-enclosed areas such as garages, narrow corridors, underground passages, or at any other places where they is smoke. When the stove is connected to the exhaust gas pipeline, it is necessary to bring professional chimneysweep to verify that the chimney does not even have the tiniest cracks or fissures. If in the exhaust gas chimney there are such cracks, the pipe for smoke exhaustion must be wrapped in insulation for proper functioning.

For this purpose, the tubes that can be used are solid and made of painted steel (minimum thickness 1.5 mm) or from stainless steel (minimum thickness 0.5 mm).

The smoke extraction system (chimney) out of metal pipes must have a grounding in accordance with existing standards and regulations. Grounding is required by law.

The grounding connection must be separated from the grounding for the stove.

The smoke exhaustion pipe must be done according to the standards in terms of dimensions

and materials used for its construction (Figure 1).

A) The top of the chimney is resistant to wind

B) Maximum cross section is 15 x 15 cm or a 15-cm diameter, with the maximum height of 4-5 m.

C) Gasket

D) Inspection hole - for control

Flue pipes that are in poor shape, or are made out of inappropriate materials (asbestos cement, galvanized sheet, etc. with rough or porous surfaces) are inadequate and jeopardize the proper functioning of the stove.

The smoke can be drained through a classic smoke pipe (see next Figure), provided that it meets the following requirements:

- Check the maintenance of the drain flue pipes or chimneys. If the smoke drain pipe is old it should be replaced with a new one. If the chimney is damaged it is good to repair it or rebuild it by inserting a steel pipe that is properly insulated with mineral wool.

- The smoke can be discharged directly into the smoke pipe (chimney) only if it has a cross-section of up to 15 x 15 cm, or a diameter of up to 15 cm, and if there is a cover for checking and cleaning.

- If the chimney has a larger cross section than 15x15cm, or a diameter greater than 15cm, a possible

increased regulation of draft (its decrease) in the chimney can be made in three ways:

1. If in the bottom of the chimney there is an opening for cleaning it should be partially open.

2. Insert a steel pipe in the chimney with a diameter of 10cm, if there is a possibility for such reparation of the chimney.

3. By adjusting certain parameters in the stove. This adjustment must be done only by an authorized service of GORENJE.

- Make sure that the connection to home chimney is properly sealed.

- Avoid contact with material that burns easily (such as wooden beams), and in all cases they should be isolated with anti-fire material (see Figure 2).

A) Mineral wool

B) Steel pipes

C) A baffle plate.

The stove is designed to be connected to the chimney flue pipes with a diameter of 80mm. If you are not using a standard chimney, but you have a new chimney, or you are modifying the existing one, use insulated stainless pipes (double wall) with a diameter given in Table 1. Flexible pipes are not permitted.

SYSTEM TYPE DIAMETER mm SYSTEM MARK

Pipe length less than 5 m 80 acceptable

Pipe length more than 5 m 100 required

To be installed in places above 1,200 meters above sea level 100 recommended

Table 1

Figure 1 Figure 2

When using the connecting pipe between the stove and the flue drain pin, be sure to use a "T" connector (as shown in Figures 5 and 6), with the clean-out cover (cap) next to the stove. Applying the "T" connector must enable the collection of ash, which is produced inside the tube, and the smoke drain pipe must occasionally be cleaned without having to remove the tube. The smoke is under mild pressure and therefore it is required to check the cover (cap) for cleaning the exhaust gas system that is perfectly sealed and it remains so after each cleaning. Make sure to perform the same sequence for assembly and check the condition of the seals.

Install the flue pipes pursuant to Figure 7.

It is strictly recommended to avoid the use of horizontal extensions, and if necessary, make sure that the pipe is not bent but that it has the slope of at least 5%. The horizontal part of the drain flue pipes must not in any case exceed the length of 3 m.

It is not recommended to connect the smoke exhaust directly to the stove with a horizontal part longer than 1 m. See Figures 4,5,6 and 8. After the T branch it is necessary to set up a vertical extension of Ø 80mm in length for at least 1-1.5 m, and only after that to move to the horizontal extension of Ø 80mm and a vertical extension of Ø 80 or Ø 100mm, depending on the height of the flue pipe (chimney) as shown in Table 1.

When connecting the stove to the chimney using fittings, one must install a knee with a hole for cleaning

(Figure 2a). Using the knee with an opening for cleaning allows for regular cleaning, without the need to

dismantle the pipes. Drain gases in the chimney connector are under mild pressure so it is necessary to

check that the cover for cleaning the ashes is completely sealed and to seal it after each cleaning. Please

make sure everything is properly returned to its place, and check the condition of the seals.


12

Figure 2a: Cleaning elements

Ideal vacuum primarily depends on the absence of barriers such as narrowing and/or corner connectors. It is recommended that the knees are 30°, 45 °, and 90 °. Knee at 90 ° shall be three-fold (Figure 2b).

In any case, it is necessary to ensure that the initial part of the vertical flue pipe has the length of at least

1.5 m. Only in this way can you achieve the proper removal of flue gases.

4.3 INSULATION AND THE DIAMETER OF THE OPENING (HOLE) ON THE ROOF (OR IN THE WALL)

Once you determine the position of the stove, it is necessary to make a hole through which a smoke pipe must pass. This varies depending on the type of installation, diameter of the exhaust gas pipe (see Table 1) and the type of wall or roof for the tube to pass. See Table 2. Insulation needs to be made out of mineral wool with a nominal density greater than 80 kg/m2.

Above all it is necessary to provide the PERFECT AIRFLOW (draft) in pipes for smoke exhaustion that has to be free, without any obstacles, such as different narrowing or corners. All displacements of the axis must have a tilted orbit with a maximum angle of 45 degrees from the vertical, while 30 degrees is the best solution. This displacement would be best done near the top of the chimney resistant to the wind.

According to the regulations (the top of the chimney resistant to wind, distance, and placement of the stove) the distances shown in Table 3 must be met:

Roof slope: The distance between the ridge and the chimney cap

Minimum height of the chimney measured at the top slot (at the back of the chimney)

α Distance in meters Height in meters

150 less than 1.85 m greater than 1.85 m

0,50 m above the ridge

1,00 m from the slope of the roof

300 less than 1.50 m

less than 1.50 m




greater than 1.30 m




greater than 1.20 m



Table 3

However, it is required to provide an initial vertical extension of 1,5 m (minimum) in order to provide proper discharge of smoke.

4.4 COMBUSTION AIR SUPPLY (Figure 8)

The air required for combustion, which is taken from the environment, must be supplied by a single ventilation grill mounted on the outer wall of the room. This will ensure better combustion and thus lower consumption of pellets. It is not recommended to have outside air drawn directly from the tube, as it will reduce the efficiency of combustion. A ventilation shaft must always be equipped with one ventilation grille on the outer side as protection from rain, wind, and insects.

This hole must be made on the outer wall of the room where the stove is located.

The supply of combustion air from the garage, a warehouse for combustible materials, or from a room where there are risks of fire is prohibited.


16

The opening of the outer supply of combustion air must not be connected by pipes.

If the room has some other devices for heating, the supply of combustion air must ensure the amount of air that is required for proper operation of the device.

Figure 8: Minimum gaps for setting up ventilation grilles.

For proper and safe placement of ventilation grilles see data given in Table 4. These are the minimum distances from each airspace or smoke extraction. This value can change the configuration of the air pressure. It should correspond to the ordering to secure that the open window draws outside air, depriving the stove of it.

Ventilation grid must be set up at least

1 m under doors, windows, gas exhausts, air chambers, etc.

1 m horizontally from

0.3 m above

2 m from the smoke exhaust

Table 4: The minimum distance for the supply of combustion air

4.5 CONNECTING THE POWER

These stoves are connected to electricity. Our stoves have electrical cables that are suitable for medium temperature. If you need to replace the power cord (if it is damaged, for example) then consult with our authorized technical staff. Before you plug in the electric stove note the following:

- That the characteristics of electrical systems correspond to the information that is specified in the data on the identification plate on the stove.

- If the smoke extraction system is metal, it must have a grounding terminal in accordance with the existing standards and legislation. Grounding is the law.

- The electrical cable must not at any time reach a temperature that is 800C above the ambient temperature. When the stove is installed and placed in its spot, a bipolar switch or socket must be easily accessible.


17

- If the stove is not used for a long time, unplug it or switch to the switch off (0) position.

In the event of failure or malfunction, turn off the stove right away or switch to a switch off (0) position and contact an authorized service center.

5. IMPORTANT INSTRUCTIONS

THE FOLLOWING INSTRUCTIONS ARE REQUIRED FOR THE SAFETY OF PEOPLE, ANIMALS, AND PROPERTY.

We wish to inform the installer of the stove on some of the general guidelines which must be followed for proper installation and for proper stove mounting. These standards are required, but not completely. For further and more detailed information one needs to read the rest of this instructions manual.

- Plug the stove into an outlet that is grounded. Figure 9

- The switch on the rear of the stove is set to position 1. Figure 10

- Do not allow children or pets to be near the stove.

- Use pellets only, not other fuel.

- Notify all users about the potential risks and dangers and teach them how to handle the appliance.

- If the stove is placed on a wooden floor, then it is recommended to isolate the pedestal on which it stands.

The stove operates with a combustion chamber, which is in the negative pressure. Therefore, make sure that the smoke is well thermally insulated.

When the stove is turned on for the first time then, due to the stabilization process a small amount of paint (not harmful to health) that covers the stove vaporizes. It is therefore necessary to air the room so that it is cleared from the fumes.

Figure 9 Figure 10

6. WARNING SAFETY MEASURES FOR STAFF

MAINTENANCE

The contractors who work in maintenance, in addition to following all safety measures, must:


18

- Always use safety equipment and personal protective equipment,

- Turn off the power supply before they start working,

- Always use the appropriate tools,

- Before they begin any work on the stove they need to keep in mind that it should be cold and that the ashes should be cold as well. They need to make sure the handles are cold as well.

− NEVER TURN THE STOVE ON if there is just one of the safety devices that is defective, improperly set

up or it does not work at all.

- Do not make modifications of any kind, for any reason, other than those permitted and explained by the manufacturer himself.

- Always use original spare parts. Never wait until the components wear out before you replace them.

Replacing the worn parts, or the components of the stove before they stop working contributes to the prevention of damage caused by accidents due to sudden failure, or breaking of the components, which can lead to serious consequences for people and/or property located around the stove.

- Clean the firebox before lighting the stove.

- Make sure there is no condensation. If condensation occurs it shows that there is water from the cooling smoke.

We recommend you find the possible causes to be able to establish a regular and correct operation of the stove.

6.1 WARNING SAFETY MEASURES FOR THE USER

The place where the stove is to be set up, called the mounting place, must be prepared by local, national, and European regulations.

The stove is a “heating machine" and while it is on it has outer surfaces that are very hot or that achieve very high temperatures.

This stove is designed to burn fuel from pressed wood mass (a pellet with a diameter of 6 mm to 7 mm, with the length of 30 mm, with maximum moisture 8-9%).

It is therefore very important to pay attention to the following when the stove is on:

- Do not approach and touch the glass on the door, there is a BURNING HAZARD

- Do not approach and touch the smoke drain pipe, there is a BURNING HAZARD

- Do not do any cleanups

- Do not open the door because the stove is working properly only when it is sealed

- Do not throw away the ashes when the stove is ON

- Children and pets need to stand away from the stove

- FOLLOW ALL INSTRUCTIONS GIVEN IN THIS MANUAL

Likewise, the proper use of biofuel pellets means:


19

-7 mm, maximum length 30 mm, maximum moisture content 8-9%,

- Do not use the stove to burn waste,

- Always perform all operations with maximum security measures.

7. SAFETY GUIDILINES FOR IGNITION AND CLEANING OF THE STOVE

- For turning the stove ON never use gasoline, kerosene or any other flammable liquid. Keep these types of fluid away from the stove while it is running,

- Never turn the stove ON if the glass is damaged. Do not strike the glass or the door so that they do not get damaged,

- While the stove is ON, do not open the door to clean the glass. Clean the glass only when the stove is cold, using a cotton cloth or paper towel and a glass cleaner,

- Make sure the stove is secure to prevent any movement,

- Make sure that the ash box is inserted and that it is fully closed, so that the doors are leaning properly on the box,

- Make sure the stove door is firmly closed while the stove is ON,

- Use a vacuum cleaner to pull the ashes from the stove only when the stove is completely cool,

- Never use abrasive cleaners for cleaning the surface of the stove.

7.1 ROUTINE CLEANING AND MAINTENANCE DONE BY THE USER OF THE STOVE

Use a drum shaped vacuum cleaner that can facilitate cleaning the stove. The vacuum cleaner must have a filter that will prevent the sucked dust to go back into the room where the stove is located.

Before you get started with routine maintenance, including cleaning, take the following precautions:


20

- Turn off the stove from the power supply before you start doing anything,

- Before you start doing anything make sure the stove and the ash are cool,

- Use the vacuum cleaner to vacuum up the ash from the combustion chamber every day,

- Using the vacuum cleaner carefully clean the firebox every day (after each use and when the stove is cool)

- Always make sure the stove and the ashes are cool.

- FIREBOX (box-shaped) - it burns the pellets made out of wood mass. See Figure 11. It is recommended that the firebox be vacuum cleaned after each use, every day (when the stove is cool). Every day, it is recommended to take out the firebox and to make sure that there is no residual ash at the bottom of it, as well as unburned pellets that were collected at the bottom of the firebox. Then put the firebox back and set it firmly into place to ensure the safe running of the stove. The firebox must sit straight - horizontal, it must not be tilted! The sealing tape from the underside of the firebox must be in its place, and must not be damaged.

If you are not sure, do not hesitate to call an authorized service center for explanation and additional information, since the manufacturer does not know what the situation is with the connection and maintenance of the stove and gives no warranty for the connection of the stove and its maintenance.

The manufacturer does not assume any responsibility for damage caused by third parties.

Figure 11

2. The hole for inserting the heating element to burn fuel

1. For the best operation of the stove, all holes must be free of ash

Figure 11


21

The ash container should be vacuumed or emptied if it is full.

Make sure the stove and the ash are cool.

Upper ash container must be cleaned every or every other day, by vacuuming or by simply throwing the ashes away. This will get rid of any impurities that remain inside when the pellets are burning. The container then has to be returned to its proper place. Never put a pellet that has not burned in the ash container.

Lower ash container must be cleaned once every seven or 10 days, by vacuuming or by simply throwing the ashes away. Before that, loosen the two butterfly nuts. This will get rid of any impurities that remain inside when the pellets are burning.

At the same time, use a vacuum cleaner to suck up the ash in the smoke chamber through an opening in the front of the boiler bottom ash tray.

The container then has to be returned to its proper place.

- SMOKE PIPES IN THE BOILER

They need to be cleaned manually with a special key for every 40-50 kg of spent pellets (one full tank of pellet). First use the key to lift up small round lids with openings, two of them, that are located on the cover of the stove at the top. Using the same key go into the openings of the lever - the pins which are connected to the cleaning levers, and dust them a few times by lifting them up and putting them down, as shown in Figure 12.

Figure 12 Figure 13

- UPPER SMOKE CHAMBER

Should be manually cleaned for every 90-100 kg of spent pellets (two full tanks). Lift the tank lid for the pellet. In the tank, in the upper front part, under the lid, there is a button for the chamber cleaning mechanism. By pulling the mechanism button a few times back and forth you will clean the chamber. Do not worry if the mechanism moves slowly, if it scratches, or gets caught. This is how it cleans the chamber.

Clean the stove only when it is cold. At the end of the cleaning, push the button all the way back (pull it) so that you can see the button and the bar of the cleaning mechanism. See Figure 13.

-GLASS DOOR (check and clean periodically):



22

Clean the glass with a soft cloth. Glass is made from pyrocheramics resistant to high temperatures. In case of damage, before re-using the stove, replace the glass. The glass must be replaced only by the authorized persons.

Smoke exhaust fan area should be checked and cleaned every six months.


Cleaning the interior flue exhaust is done by first removing the cover on the bottom of the box for the ashes and inserting the vacuum cleaner hose through that hole, as to vacuum out the remaining ashes, Figure 14.

Figure 14

- GENERAL CLEANING AT THE END OF THE HEATING SEASON

Make sure the stove and the ash are cool - unplug the stove from the power supply.

At the end of the heating season, to be safe, unplug the stove from the power supply. It is important to clean and check the stove, as explained in the above points.


After prolonged use, it is possible that the asbestos tape for sealing the door separates. This sealing tape sticks to the door with silicone resistant to high temperatures. To resolve this, tape the back of it using an adhesive that is resistant to high temperatures. This is very important for good sealing of the doors.

7.2 CLEANING AND MAINTENANCE (for employees who do maintenance)

FLUES - CHIMNEY should be cleaned every six months or after burning two tons of pellets.


The smoke channel (chimney) is resistant to wind and has to be checked and cleaned every year, best at the beginning of the heating season. It is best to pay the authorized professional contractors for their cleaning. The places that need special attention when cleaning are shown in Figure 15.


23

Figure 15: Places that need to be cleaned at least twice a year

7.3. SPECIAL MAINTENANCE

Your stove is a heat generator that uses pellets as solid biofuel. This is why you should do special maintenance once a year.

This is best done at the beginning of the heating season.

The purpose of the special maintenance is to ensure proper and efficient operation of the stove.

8. IMPORTANT SAFETY INFORMATION

You have purchased a product of the highest quality.

The manufacturer is always at your service to provide you with all the information you may need regarding the stove and instructions for assembly and installation in your geographical conditions. Properly connecting the stove, according to these instructions, is very important to prevent the danger of fire and any defects.

The stove works with a combustion suction pressure. Therefore, make sure that the smoke is well thermally insulated.

DANGER !

In case of fire in the smoke exhaust pipe take all the people and pets out of the room, unplug the power supply using the power switch in the house or remove the plug from the wall (plug must always be easily accessible and free of obstacles), and immediately call the fire department.

DANGER !

You cannot use conventional firewood.

Places that need to be cleaned at least

twice a year.


24

DANGER !

Do not use the stove to burn waste.

9. THE PELLET QUALITY IS VERY IMPORTANT

This stove uses pressed wood (pellet) as fuel.

As there are many products like this on the market it is important that you select pellets as fuel that is not dirty. Make sure you use high quality pellets that are compact and with a little bit of dust.

Ask your sales representative or the manufacturer for the best pellet, with a diameter of 6 - 7 mm, the longest side 30 mm. Proper operation of the stove depends on the type and quality of pellets, since the heat obtained from different types of pellets can be of varying intensity.

When the pellet is poor quality the stove will have to be cleaned more often.

Manufacturer of the stove does not bear any responsibility for poor performance of the stove in case of use of the pellets of inappropriate quality.

9.1. STORING THE PELLET

The pellets must be kept in a dry place that is not very cold. Cold and moist pellets (at the temperature of around 50C) reduce the thermal power of the fuel and require additional cleaning of the stove.

THE PELLETS MUST NOT BE KEPT CLOSE TO THE STOVE. Keep them at least 2m away from the

stove. Handle the pellets carefully and do not break them.

WARNING: If the fuel tank is filled with sawdust or small (decomposed) pellets, it can prevent the insertion of the pellets. Such pellets can lead to burning the electric motor that drives the mechanism for the insertion of pellets, or damage the gear that works in conjunction with this electric motor. If the bottom of the pellets reservoir, or, at the bottom of the gear unit when the tank is empty you see such a pellet, suck it up with a vacuum by swiping the tube through open grates of the pellets.


25

10. CONNECTING THE HYDRAULIC INSTALLATIONS

IMPORTANT:

Connecting the stove on a hydraulic installation can be done exclusively by qualified technicians, who can do this in accordance with applicable regulations of the country in which the installation is done.

GORENJE disclaims all liability in case of a material or bodily harm, in the event of failure, poor functioning, if the above recommendations are not followed.

The stove is designed for central heating.

The stove is prepared for a closed heating system. Follow the SRPS guidelines.

11. PRESSURE AND RETURN PIPE

Outputs of the pressure and return pipes on the boiler are 1'' and you cannot reduce them or taper to the first bifurcation. Use a 1’’ steel pipe or a copper pipe with the outside diameter of Ø28mm or greater.

When installing, strictly observe the slopes of pipes as they need to be at 0.5% (5mm. per meter of pipe) and the venting system (boiler, pipes, radiators).

Set up a thermo hydrometer at the pressure line to show the water pressure in the system and the water temperature at the back end of the boiler.

12. BUILT-IN COMPONENT OF THE STOVE

- In the stove, there are the following built-in components:

- Safety valve

- Circulation pump

- Automatic air valve

- Expansion container and

- Charging and discharging tap

For this reason there is no need to install these components again. The stove is complete, which is a great advantage most all of because there is no need for additional space for the listed components.


27

12.1. SAFETY VALVE

It is set up under the lid of the stove on the pressure line. Input connection is R1/2". It opens with water pressure of 2.5 bar. You can get to it by removing the right lateral side, when you are looking at the stove.

The output safety valves whose connection protrudes through the rear wall above the pressure line should be put into the sewer pipes.

12.2. CIRCULATION PUMP

A high-quality Wilo RS 25/6 – circulation pump has been built into the stove on the return line of R1”. The power of the pump is 93W. It is turned on and off by the electronics by the set water temperature.

The pump shaft has to be in a horizontal position. For this reasons, when connecting with the installation make sure that the pump does not turn around! Firmly hold galvanized bolt at the end of the back side.

You can reach the pump by removing the left lateral side, when you are looking at the stove.

Note:

If the stove and the pump have been idle for a long time (a month, for example), the pipe shaft can stick to the base, it may not move the water, or it can burn out. If when starting the stove when the water in the boiler heats up the water pump does not start, if the radiators do not heat up when the set temperature is reached, if you do not hear the murmur of water (moving), or if the boiler temperature rises and radiators are not warming, remove the left lateral side as indicated in the previous paragraph, and get to the pump. Put a cloth under the pump and using a flat screw driver with the tip width of 5 - 7mm, unscrew the short screw from the front of the pump. There will be a little bit of water coming from the pump, which is normal. Push the screw driver into the opening of the pump, reach the groove of the pump shaft and rotating the screwdriver and the shaft to the right and left break in the pump shaft. Put the pump screw back in its place into the opening of the pump and tighten it. Make sure that the rubber from under the screw does not come out.

12.3. AUTOMATIC AIR VALVE

There is an automatic air valve on the pressure line under the lid. It is suppose to drain the air out from the boiler.

You can get to it by removing the right lateral side, when you are looking at the stove.

The cap valve must be loose, not tight, so that the air can come out of the boiler and installations smoothly.

12.4. EXPANSION VESSEL

There is an expansion vessel built into the stove with a volume of 10 litres. Its function is to stabilize the pressure in the boiler and in the heating installation. The factory set pressure in the vessel is 1 bar.

12.5. CHARGING AND DISCHARGING TAP

As its name says, this is a charging and discharging tap.

It is located in the back side, down.

The input connection is a R1/2”, while the output has an extension for the hose.


28

13. INSTALLING AND IGNITING Before the combustion starts entire system of central heating should be water-filled, well-vented, and the stove properly connected to the chimney, as discussed in previous counts.

Recommended operating pressure of water is 1 to 1.9 bar. Best to be within the limits of 1.2 to 1.6 bar.

The test pressure can be up to 1.9 bar.

NOTE:

The stove must not be used without water. It must be tied to the installation to which the consumers are connected (radiators) with minimum power of 8 kW.

14. PRACTICAL INSTRUCTIONS AND TIPS FOR THE USE OF THE HEATING SYSTEM

-All connections must be well sealed and fastened. There must be no leakage of water.

-Before you turn the stove on for the first time, the complete installation shall be tested with water at a maximum pressure of 1.9 bar.

-It is preferred that the water be at least once released out of the system due to the dirt which is located in the system.

-Make sure that all valves between the stove and the installation are open.

-Make sure that all the air from the boiler and installation is released before placing the boiler in operation. For this reason, the installation should be filled with water slowly so that the air manages to get out of the installation.

-During the ignition and cooling phase, the stove can expand and contract, and at the same time you can hear little crackling. This is absolutely normal, because the structure is made of steel and this certainly can not be regarded as a disadvantage.

Basic programming that is done in the factory guarantees proper operation and prevents overheating problems when you first turn on the stove, and for later as well.

15. FILLING WITH WOODEN GRANULES

Refuelling is done on the upper side of the stove by opening the lid. Put the wooden granules in the tank. Its load capacity when it is empty is about three 15 kg bags, a total of 45kg of pellets.

To simplify the procedure, do this in two stages:

-Put half a bag into the tank and wait until the pellets reach the bottom. Turn the stove on. -When the stove starts to work normally put the pellets as needed in the storage for pellets. -Do not ever remove the security grid from the tank. When putting the wooden granules in, prevent the bag from coming into contact with hot surfaces.

ECOLOGIC 30 | instructions for use, maintenance and installation | June 2015

2

We thank you for your purchase of Gorenje pellet boiler. We ask to thoroughly read instructions for

use before installing and using your pellet boiler ECOLOGIC 30. Heating appliances (in the

following: "pellet boiler" or "boiler") of company Gorenje d.d. (in the following: Gorenje) are

manufactured and tested in accordance with safety requirements of European Directives in force.

These instructions are intended for end users, installers and authorized maintenance personnel for

Gorenje pellet boilers. If you have any doubts regarding the instructions for use or require any

clarification, please contact the manufacturer or authorized person of company Gorenje d.d.

directly.

Printing, translation or reproduction, even in part, of the instructions of use is possible only upon

approval by company Gorenje d.d..

You have purchased a Gorenje boiler, which is used for central heating of surfaces from 80 m2 to 400

m2. The fuel for the boiler is wood pellets. The boiler operates automatically by dosing pellets with a

dosing screw from pellet container, which is a component part of device and is installed above the

boiler part of the device. The container is filled with pellets from above, through the provided cover.

Ensure that the incineration device is correctly dimensioned according to heating system and thermal

requirements of the building. Connection and start-up of the machine must be done by an authorized

person.

Flame, produced with correct burning of wood biomass inside the boiler, emits the same amount of

carbon dioxide (CO2) as with normal decomposition of wood.

The amount of CO2 produced by the combustion or decomposition of wood corresponds to the

amount of CO2 that a tree obtains from the environment and then transforms to oxygen and carbon.

The use of non-renewable fossil fuels (coal, fuel oil, gas), as opposed to what happens with wood, re-

leases into the air enormous amount of CO2 accumulated over millions of years, which increases the

greenhouse effect. The principle of clean combustion fully meets all environmental requirements,

and ECOLOGIC 30 has based its entire development on this basis.

2.2. TRANSPORTATION AND HANDLING OF PELLET BOILER

When moving the boiler, pay attention to your safety.

Before transport and handling of the boiler, which must be performed in complete safety, make sure

that the lifting capacity of transport equipment suffices. Avoid sudden and/or abrupt movement of

boiler.

ATTENTION

DISCARD ALL PACKAGING OUT OF REACH OF CHILDREN. DANGER OF SUFFOCATION WITH

BAG, FOIL, POLYSTYRENE ETC.

2.3. RESPONSIBILITY OF INSTALLER

It is the responsibility of the installer to check adequacy of installation and pipeline, ensure air intake

for combustion, ensures regulated distances and all other solutions, required for installation of the

pellet boiler.

It is the responsibility of the installer to ensure compliance with local legislation in force in the place

of pellet boiler installation.

Use of the pellet boiler must conform with instructions, provided in Instructions for use, maintenance

and installation, and all safety standards, specified by local legislation in the place of pellet boiler

installation.

Standard UNI 10683 defines duties of installer. The installer must check:

type of device to be installed;

adequacy of space for installation of unit, reflected by minimum required size of the space, in which the pellet boiler will be installed;

instructions of the manufacturer about heating device, regarding requirements of smoke

gases outlet;

flue pipe internal diameter, the material it is made of, is it straight or even and that there are

no obstructions;

height and, if required, vertical extension of flue pipe;

existence and suitability of flue pipe cover resistance;


7

possibility of outside air intake;

possibility of simultaneous use of generator for connection with other equipment.

If the results of all above provided checks are positive, installation may proceed. Carefully heed to

instructions provided by the manufacturer, as well as safety and fire prevention standards in force.

After the first start-up of the boiler, perform a minimum 30-minute test of operation to check all

required demands.

When the installation is complete, the installer must provide the customer with the following:

instructions for use, maintenance and installation from the manufacturer (if not included in

the unit);

required documentation in accordance with standards in force;

perform training of customer for operation and regular maintenance and cleaning of the

device.

3. INSTALLATION

Responsibility for installation work in the space is entirely upon the customer.

Before proceeding with installation, the installer must comply with all required legal safety standards,

especially:

Check that norms regarding pellet boiler installation meet local, national and European

norms

Heed to requirements set forth in this document

Check that pipes and air intake are compliant with the type of installation

Do not make temporary electrical connections by using unsuitable cables

Check earthing of electrical system

Always use individual safety equipment and all legally required protection

Always allow sufficient space for maintenance work

Acquire consent of chimney sweep for connection of boiler to flue

Perform measurement of smoke gases outlet after finished installation.

3.1. PLACEMENT

It is advisable to remove pellet boiler packaging only when it is in the place of installation.

If the adjacent walls and/or flooring are made of material that is not heat resistant, suitable

protection must be provided using insulating, non-combustible material.

For protection of flooring, made of flammable material, we advise installing a metal plate with

thickness 3 to 4 mm under the boiler, which protrudes at least 30 cm out from the front of the pellet

boiler.

Pellet boiler must be installed in accordance with drawing that defines distances from walls (figure 1).


8

Figure 1: Minimum distance of boiler from boiler room walls

Flue pipe

EXAMPLE 1

EXAMPLE 2

Flue pipe

Flue pipe

EXAMPLE 3


9

If the pellet boiler is installed in a boiler room, where there are other devices, which drain air (other

boiler, various suction fans etc.), make sure that the volume of air intake is sufficient for safe

operation of combustion device.

If the smoke duct passes through a ceiling, it must be properly insulated using diaphragm of non-

combustible insulation material.

When the pellet boiler is placed, it must be levelled with support feet (horizontal positioning).

ATTENTION

Smoke gas discharge MUST NOT BE CONNECTED TO:

Flue pipe, used by other combustion devices (boilers, stoves, fireplaces etc.);

Air extraction systems (hoods, air extraction fans etc.).

ATTENTION

Installation of draught closing valves is prohibited! Flue connection Ø 80 mm from pellet boiler to flue pipe should be:

no more than 5 m long (in case of longer connection, dimension of connection pipe must increase to Ø 130 mm);

each 90° joint requires a 1 m shorter flue connection;

each joint must be fitted with doors for cleaning;

connections between pipes must be sealed.

ATTENTION

If there is too much resistance in extraction system (many joints, improper end fitting, bottlenecks etc.), extraction of smoke gases is not provided for. Therefore, connection pipes and joints must be increased to a greater dimension – Ø 130 mm. If the flue does not ensure appropriate extraction of smoke gases, it can also come do improper operation and, consequently, to alarm from boiler ECOLOGIC 30. It is advisable that the flue is inspected by an expert before installing boiler ECOLOGIC 30.

Smoke gases extraction system from pellet boiler functions on the basis of negative pressure in the

boiler and barely perceivable pressure in flue connection pipe Ø 80 mm. It is very important that the

smoke gases extraction is sealed.


10

Layout and structure of the space, where the flue is installed, needs to be analyzed. If it passes

through walls and/or roof, it must be properly installed in accordance with fire prevention safety

standards.

Ensure that there is enough air for proper combustion in the space, where the pellet boiler is

installed. If boiler ECOLOGIC 30 lacks oxygen/air, the boiler displays an alarm. External supply or

intake of external air requires a pipe with a diameter of at least 110 mm with maximum length of 10

m. Each 90° joint requires a deduction of 1 m in line length. If the air supply is longer, diameter of air

intake pipe must be increased.

In case of a grid on the facade, draught opening must be 100 cm² or larger.

The device operates at 220 V – 50 Hz. Make sure that the electrical cables are not laid under the

boiler, that they are far away from hot surfaces and that they do not touch sharp parts, which could

damage them. If the pellet boiler is under electrical overload, life expectancy of electrical component

greatly reduces.

ATTENTION

Never turn off the boiler by pulling the electrical cable from the socket, while fire is still

burning in the boiler. This could damage the boiler and seriously jeopardize its functioning.

3.2. EXTRACTION OF SMOKE GASES

Extraction of smoke gases must be in accordance with regulations in force. Pipes for smoke gases

must not be connected to other discharge pipes of any other combustion device (figure 2). It is

prohibited to set up extraction of smoke gases into closed and/or semi-closed spaces, e.g. garage,

narrow passages or hallways, underpasses or any other similar spaces. If the flue connection is not

suitable, it must be implemented in accordance with previously provided requirements (point 3.1).

Figure 2

YES NO


11

ATTENTION

Extraction of smoke gases must be earthed in accordance with regulations in force. (Earthing

connection is required by law).

Earthing must be independent of combustion unit.

Regarding dimensions and material, from which it is made, the flue pipe must conform to standards

UNI 9615-9731, UNI 10683 - EN1856-1.

Flue pipes in poor condition and/or made of unsuitable materials (asbestos, zinced sheet metal etc.,

with rough or porous surfaces) are prohibited by law and compromise proper boiler operation.

Smoke can be extracted through a traditional flue pipe (see figure below) provided that the following

rules are met:

Check condition of flue pipe maintenance. For proper maintenance and/or restoration

contact chimney sweep service.

Extraction of smoke gases can be connected directly to flue pipe only if it has a maximum

dimension of 20 x 20 cm or diameter of 20 cm and is fitted with inspection hole.

If the flue pipe is of greater dimensions, a stainless pipe (with required diameter) with proper

insulation must be installed into it.

Make sure that the connection with the flue pipe is properly sealed.

Avoid contact with flammable material (such as wood ashes), and, in any case, insulate them

with fire-resistant material.

When using connections between the pellet boiler and flue pipe, it is mandatory to use joints with

cleaning doors (figure 3). Use of joints with cleaning doors enables regular cleaning without the need

to disassemble pipes. Exhaust fumes in flue connection are under slight pressure. Therefore, it is

compulsory to check that the cover for cleaning ash is completely hermetically closed and that it

remains in this state after each cleaning. Ensure proper reassembly and check condition of the seal.

Figure 3: Cleaning unit


12

Connection between pipes must be always made with male fitting turned upwards (figure 4).

It is advisable to avoid using horizontal connections of pipes to flue. If this is not possible, the pipes

must not be installed in a downwards angle, but at an upwards angle of at least 5 % (figure 5).

Horizontal installation of pipes must not exceed 2 m in length.

It is not advisable to connect the pipe from the pellet boiler directly to flue with horizontal pipe,

longer than 1 m.

Figure 4 Figure 5

3.3. INSULATION AND DIAMETER OF HOLES IN THE ROOF

Once the position of boiler installation is determined, a hole for passage of smoke pipes must be

made. This changes in regard to the type of installation, diameter of smoke pipes and type of wall or

roof, through which it must be guided. Insulation must be of mineral origin (rock wool) with nominal

density greater than 80 kg/m³.

Perfect draught depends mostly on flue pipe, which must be free of obstructions, such as bottlenecks

and/or various joint connections. Joint must be at an angle of 30°, 45° and 90°. Joints at an angle of

90° must be made of three parts (figure 6).

In any case, it is mandatory to provide an initial vertical straight pipe of 1,5 metres in length

(minimum) to ensure correct extraction of smoke gases.

Figure 6

3.4. INLET AIR

Air from the environment, required for correct combustion, must be refreshed with new air, through

opening in the wall, slot in boiler room doors or grid on the window. This will ensure proper

combustion and proper boiler operation.

Opening for intake of fresh air must also be fitted with protective slot against rain, wind and insects.

Hole must be made on the external wall of the space, where the pellet boiler is installed.

Standard UNI 10683 prohibits intake of inlet air from storage of flammable materials or spaces with

the risk of fire.

If there are other combustion devices in the room, a sufficient amount of air must be ensured, which

is required for proper combustion of all combustion devices, and regard all technical properties of

already installed ventilation systems in the boiler room.

Figure 7

3.5. ELECTRICAL CONNECTION

Combustion device requires connection to electrical network. Our pellet boilers are fitted with power

supply cable for medium temperatures. If the power supply cable is damaged and must be replaced,

contact our service staff.

Before making electrical connections, make sure that:

The characteristics of electrical wiring meet the data, given on the combustion device.

Extraction of smoke gases is earthed in accordance with regulations and local requirements

in force. (Earthing is required by law).

100 cm2 or more


14

Power supply cable must never reach 80 °C above ambient temperature. If you want to

connect the boiler directly to electrical network, you must install a bipolar switch with

minimum distance of 3 mm between contacts, suitable for required electrical voltage and in

accordance with regulations in force. Bipolar switch must always be accessible, even after the

boiler is installed.

Electrical connection

The pellet boiler must be connected to electrical network. Power supply cable is 3 m long, white and

designated with "220 V". Other connection cable is intended for connection of pump, is black and

designated with "Pump".

Figure 8

6.1. REGULAR MAINTENANCE AND CLEANING OF BOILER

Use of vacuum cleaner with separator will make cleaning ashes from the boiler easier.

Before starting any kind of maintenance, also cleaning, heed to the following safety precautions:

Shut off the pellet boiler before performing any kind of work

Before performing any kind of work on the boiler, make sure that the ashes in the boiler are

cool


18

Vacuum ashes from the combustion at least once every ten days or at each used pellet container

(only when the boiler is cool) (figure 10).

Vacuum and carefully clean the combustion container at least once every ten days or at each used

pellet container (only when the boiler is cool) (figure 10).

Once a month, remove the front door at the bottom of the exchanger on the right side of the boiler

and vacuum the inside (figure 10).

Always make sure that the pellet boiler and ashes in it are

cool.

This is the combustion container for burning pellets

(figure 9). We recommend inspecting and cleaning ashes

from the bottom of combustion chamber upon each

cleaning. When you place the combustion container back

in its place, make sure that it is set correctly: it must be

pushed towards the back wall all the way. Only then you

can be sure that the boiler will function properly.

Figure 10

ATTENTION

Be careful that the sealant rope under the edge of combustion chamber is not damaged. If

the sealant rope is damaged, contact an authorized service centre.


19

If you require any explanation do not hesitate and contact your installer. Because the manufacturer

has no control of the installer's work, he cannot guarantee performance of his work and

maintenance.

The manufacturer shall in no way be held responsible for damages caused by third parties.

ATTENTION

Ensure that the pellet boiler and ashes in it are cool!

The combustion chamber must be cleaned after each used pellet container, vacuumed and/or

emptied of all impurities remaining after the pellets have burned.

Never put pellets which have not burned back in the pellet container or ash box.

6.2. CONTROL AND PARTS REQUIRING MAINTENANCE

CHECK THE FOLLOWING ITEM AND MAKE SURE THAT THE PELLET BOILER IS OPERATING PROPERLY.

THIS WILL INCREASE ITS EFFICIENCY AND THE EMITTED HEAT INTO THE SYSTEM WILL ALSO INCREASE:


For perfect cleaning, vacuum ashes from beneath the combustion container and from

combustion chamber every week or at each 200 kg pellet container used (whichever comes

sooner). Use a broom or a brush to clean firebox walls.

Clean the fan for extraction of smoke gases by removing fan protection and cleaning fan

blades with a broom or a brush.

GENERAL BOILER CLEANING AFTER THE END OF SEASON OR BEFORE THE START OF SEASON:


Disconnect power supply!

At the end of heating season, disconnect the boiler from electrical network. It is very

important to clean and inspect the boiler, as described in the instructions.


20

Door seal, fitted with high-temperature resistant fitting material, can detach after prolonged

use. To reattach it, apply high-temperature fitting material on the back of the seal. This

ensures hermetic sealing of firebox doors.

FLUE CONNECTION – CHIMNEY (must be cleaned at the end of each season):


Flue duct, chimney and chimney cover must be inspected and cleaned every year. Contact

your chimney sweep for professional service.

6.3. ADDITIONAL MAINTENANCE

Your pellet boiler is a heat generator which uses pellets. Therefore, it requires a special type of

maintenance by authorized personnel of company Gorenje d.d. each year.

Regular annual maintenance keeps the combustion device in good condition, ensures greater

efficiency, retains warranty and extends life expectancy of the device.

Type of work, described in the previous chapter, is advisable to perform after the end of heating

season. Their purpose is to check and ensure flawless operation of all components.

You have purchased a product of the highest quality.

The supplier is at your disposal in transferring required information. Correct installation of

combustion device in accordance with instructions is important to prevent any poor functioning,

hazard or risk of fire.

Pellet boiler operates on the basis of negative pressure in the combustion chamber. Therefore, always

ensure that the flue connection is thermally sealed.

ATTENTION

In the event of fire in the flue pipe, all persons and animals must leave the area, then

immediately disconnect power supply from the main switch or socket (if it is possible

without risk) and call the fire department.


21

ATTENTION

Do not use fine cut wood to ensure operation and safety of the boiler.

ATTENTION

Do not use the pellet boiler as an incinerator.

8. PELLET QUALITY IS VERY IMPORTANT

The pellet boiler is designed for use with pellets. Because the market offer many types and

dimensions of pellets, it is very important to obtain pellets free from impurities. Make sure that you

use only pellets that are compact and dust-free. Ask your supplier for suitable pellets with 5 mm

diameter 30 mm length. Proper operation of the pellet boiler depends on the type and quality of

pellets.

Pellets are filled in the pellet container from above through the opening in foldable cover of the

container (figure 11). Make sure that, during filling, no hard objects foil or other objects that could

interfere with the operation of dosing screw, do not enter the pellet container.

Figure 11


22

ATTENTION

Persons with back injuries and pregnant women should avoid lifting pellet bags.

ATTENTION

The manufacture shall in no way be held liable for damages arising from the use of poor

quality pellets, as well as for poor functioning of the boiler due to poor quality of used

pellets.

ATTENTION

Pellets should be in accordance with DIN 51731, DIN plus, Ö-Norm M-7135 or other

comparable European standards.

8.1. STORING PELLETS

Pellets must be stored in a dry and not too cold place.

Cold and damp pellets (temperature about 5 °C) reduce thermal power and require more frequent

boiler cleaning.

ATTENTION

PELLETS SHOULD NOT BE STORED NEAR THE PELLET BOILER. Keep them at least 1/2 metre

away.

When handling pellets, be careful not to scatter them.

If you fill the pellet container with sawdust, it can block the pellet dosing system.

3. Boiler connection instructions

To connect boiler ECOLOGIC 30 to central heating system you must check:

It is necessary to take into account the installations of non-return valve spring (or other

locking elements) which automatically prevent uncontrolled circulation of the heating

medium through the boiler by natural gravitational path.

Correct installation of pipelines of central heating (pipeline dimensions, air extraction, pipe

system functionality, adequacy of heating system according to boiler power).

Distribution units (pump functionality, closing valves functionality, electrical zone valves func-

tionality, mixed valves functionality…).

Ensured inlet of air into the space where ECOLOGIC 30 combustion device is installed. Inlet

must be executed in a manner, so that it cannot be closed and must, at any moment, enable

supply of fresh air – oxygen for burning into space. Unsuitable solutions are slightly opened

windows or open doors, supply of air through a duct along the flue from the roof is also un-

suitable.

Voltage of electrical connection for combustion device ECOLOGIC 30 must be 230 V / 50 Hz

(given in technical data for boiler ECOLOGIC 30).

Inspection of outlet of smoke gases – flue. Condition for connection is consent from chimney

sweep, with which a chimney sweep ensure suitability of the flue for combustion device ECO-

LOGIC 30.

In placing and connecting the combustion device to central heating system, the installer must adhere

to the following:

Boiler ECOLOGIC 30 must be positioned horizontally, in length and depth.

Distances, according to the enclosed drawing, must be regarded (see figure 1, page 7).

In cases of older installation on return line to combustion device ECOLOGIC 30, a cleaning ele-

ment with closing valves is installed.

Boiler ECOLOGIC 30 is fitted with safety valve of 2.5 bar on return line. Installer must ensure

proper size of expansion container for volume of heating water in the system (size of expan-

sion container must be dimensioned minimum of 10 % of water volume in system "150 litres

of heating water in the system, minimum volume of expansion container must be 15 l". ex-

pansion container must be installed on combustion device ECOLOGIC 30 without closing ele-

ments.

A filling release tap must be installed on the right side of the boiler, on connection DN20 (see

figure 17, page 49).

Minimal pressure of heating water in boiler of 0.7 bar is ensured.

In case where there are many heating loops (two direct loops or mix loops for radiator heat-

ing, boiler heating, convector heating), connection scheme nr. 3 (page 54) is always used,

where it is necessary to use a hydraulic switch and pump on boiler loop, which is electrically

connected to cable "pump" from the boiler (see figure 8, page 13).

Boiler must be fitted with pressure gauge for pressure of heating water in the boiler, i.e. on

pipeline before each closing valve (enable that the pressure gauge indicates pressure in the


49

boiler and system; in the time of filling "there cannot be a closing element, which could pre-

vent indication of pressure in the boiler in the time of filling"). On the right side of ECOLOGIC

30 (see figure 17, page 49) is a provided DN20 connection for filling release tap. Filling re-

lease tap is intended for filling or emptying the heating system and boiler.

When connecting the boiler ECOLOGIC 30 to central heating system you must use mechanical

elements, which prevent uncontrolled circulation of hot heating water through the boiler

(gravity block, spring non-return valve, solenoid zone valve, electromotor zone valve...). goal

of protection is to ensure amount of heating water flow through the boiler (minimal flow

through the boiler must be over 300 l/h).

When distribution of heating water is regulated by three-way mix valve (floor heating,

weather controlled regulation, where water flow on boiler heating loop is reduced), the sys-

tem is executed with fitted hydraulic switch and pump on primary-boiler heating loop, pump

on boiler heating loop must be controlled by boiler regulation, which already has a factory

produced electrical connection for pump.

When a three-way mix valve is used (for floor or radiator heating, only in case of only one

mixing heating loop), connection of boiler ECOLOGIC 30 is always executed according to

scheme nr. 3 (page 54), where a hydraulic switch and a pump are built into the installation on

heating cycle with non-return valve (pump is connected to black cable from combustion de-

vice).

Flue connection must executed in accordance with instruction limiting maximum length of

connection pipe Ø 80 (5 m) and that 90-degree joints are considered as resistance on connec-

tion, which reduces length of connection pipe for 1 m (example: if there are 2 joints on flue

connection, the connection cannot exceed length of 3 m). Flue connection must be fitted

with joints with inspections holes for cleaning (see figure 3, page 10). Joints must be out of at

least 3 segments (joints with three or more segments enable smooth flow of smoke gases

through joint), it is prohibited to use joints with two segments (joints with two segments cre-

ates resistance in flow of smoke gases) (see figure 6, page 11).

If the flue connection is longer as set forth in the instructions, the installer must use a reduc-

ing element (from Ø 80 female connection to Ø 130 female connection) immediately behind

the fan, and the connection must be made with a pipe Ø 130 (see figure 18, page 49)

Electrical connection of boiler must be performed with a cable (see figure 8, page 13) in ac-

cordance with instructions. The boiler must not be connected to power supply with a plug –

it must be connected directly to network by a toggle switch, breaking live and neutral wire

(see figure 19, page 49).

Electrical connection of distribution elements (pumps, solenoid valves, electromotor valves...)

must be executed in accordance with the scheme in the instructions, i.e. supply for distribu-

tion elements must be executed from connection cable on the boiler (cable "pump") (see fig-

ure 8, page 13).

Combustion device ECOLOGIC 30, pipes of central heating and flue connection must be

earthed in accordance with professional regulations (earthing conductor with minimum

cross-section 4mm2) (see figure 20, page 49).

ECOLOGIC 30 is a combustion device for heating with pellets. Benefits of combustion device

ECOLOGIC 30 lie in advanced technology that enables automatic identification of oxygen contents in

air, automatic identification of flue draught and automatic identification of pellet quality. When one

of the former factors is unsuitable, combustion device ECOLOGIC 30 indicates an alarm on the display

on unsuitability or fault for lacking (example: if the flue is clogged or does not provide extraction of

smoke gases, ECOLOGIC 30 displays "ALARM PRESS").

Overview of alarms is on page 31.

When the installer makes the connection to central heating system, to chimney with flue connection

and to electrical network in accordance with instructions for installers, the boiler is ready for start-up.

After checking details from instructions for installers, combustion device ECOLOGIC 30 can be

commissioned with ON/OFF button (see figure 22) by the installer, who installed the device.

Upon first start-up, the installer must be careful of correct order of events (displays):

Press and hold ON/OFF button for 3 seconds. Display indicates ON, and immediately after

"Test fire" – lasts 10 seconds, then goes to:

"Heat up" – quick filling of combustion container with pellets, alternately displaying P0 d5 (in

upper display) and changing temperatures; b – temperature of heating water in the boiler, only

number – temperature of smoke gases and r – temperature of return line (in lower display),

then goes to:

"Fuel igni" – ignition of combustion device ECOLOGIC 30 (upon first ignition, ignition phase can

last longer, even up to 10 minutes) lasting approximately 5 minutes, alternately displaying P0

d5 in upper display and temperature in lower display, then goes to:

"Igni test" – checking ignition, display also changes between igni test and P0 d5, and tempera-

tures in the lower display. When checking is done, it goes to:

"Burn" – boiler operation, upper display indicates Burn, lower display indicates changing b-

temperature of heating water in the boiler, smoke gases and r-temperature of water in the

boiler:

LED in upper display above right signals operation of reducer for dosing pellets (when the LED

is turned on, the reducer is dosing pellets into the burner and vice versa: if the light is turned

off, the reducer is not operating).

LED in the lower display below right signals when the boiler is supplying pump with voltage –

when the pump is operating (when the light is turned on, the pump is supplied with power,

which means that the pump is operating and vice versa: if the LED is turned off, the pump is

not operating),

When the temperature of heating water begins to gets closer to set temperature, combustion

device ECOLOGIC 30 starts modulation or regulation/reduction of power. In this state, display

indicates "regu H2O", and upper display alternately shows power (P is the level of boiler opera-

tion, d is the level of boiler setting), and lower display shows temperatures.

"Cool flui" – state of shutting down, indicated on the display when combustion device ECO-

LOGIC 30 reaches set temperature of heating water in the boiler with addition for regulation (if

the temperature of heating water is set to 70 °C, the boiler enter "cool flui" state at 75 °C).

When the boiler finishes "Cool flui" state, it means that the heating water in the boiler cooled

down. It goes to:

"Test fire" – and the ignition procedure is repeated.

Control of information on operation of combustion device ECOLOGIC 30 requires menu access into

programme of information (shown data is only illustrative). Enter the menu with long press on MENU

button (see figure 22, page 58), when the display shows "tH2O", release the button. Use + and -

buttons to select desired information.

Displayed information is:

tH2O temperature of heating water in the boiler

rH2O temperature of heating water on return

tFLU temperature of smoke gases ((H2O )+30-90°C),

tChb temperature of fire in combustion chamber (615°C+-40°C)

floU inlet of air-oxygen into combustion device (480°C +- 40°C)

FanI voltage on fan 1 (130V +- 15V)

FedI percentage of pellet dosing into the burner (70% +- 20%)

Once you have completed viewing information, use + and - buttons to find information "tH2O". When

finding it, short press ON/OFF button to return to previous state.

If the display indicates "alarm", cause of the alarm must be determined with alarm list (see page 31).
