Installation and operating instructions

! Important manufacturer’s instructions!

Please observe the following instructions:

Quality of wood pellets:

Depending on the manufacturer there are light, dark, shorter and longer pellets. And the quality of one delivery may differ from another even from the same supplier. The standards for wood pellets are becoming more and more strict but wood is wood and has its own characteristics regarding ash and clinker.

Your HAAS+SOHN stove

Cleaning requirements: As soon as you find ash and clinker deposits in the cold combustion pot, it must be cleaned. See operating

instructions! If this is not done, there will be more and more clinker. Then the device will no longer be able to ignite

properly. Pellets may pile up in the combustion pot. In extreme cases, this can reach all the way back to the pellet chute. Backfire in the pellet container and smouldering in the pellet tank might possibly result. This will destroy

your device and is not covered by the guarantee.

For maximum working life:

• Arrange for commissioning by your trained stove supplier.

• Observe the daily check as described and more frequently if you have received new pellet deliveries or when

the device is brought back into use after the summer.

• Carefully read through all the operating instructions and retain them.

Congratulations! You are the owner of a HAAS + SOHN pellet stove, a quality product. Please read through these instructions carefully. They will tell you all about the functions and operation of this stove, which will increase the utility of this device and extend its working life. What is more, with the correct heating you can save fuel and protect the environment.

We can only give a guarantee on our products if you observe the following instructions in these installation and operating instructions. In addition, the stove must be correctly installed so as to prevent possible accidents.

Look after these instructions well, then you will be able to familiarise yourself with the correct operation of your stove at the start of every heating period.

Note:

The installation and operating instructions given in this manual may differ entirely or in part from public authority instructions. In that event, the public authority instructions always apply! The drawings in these instructions are not to scale and serve only as illustrations.

1. Description

Pellet stoves are particularly suitable for the constant heating of residential and work rooms. The HAAS+SOHN pellet stove is set up to operate in fully automatic mode, with a choice of 2 operating modes (“Heating” and “Auto” with a weekly programme).

Depending on the room temperature and on the model, a volume of fuel for a maximum of 30 hours of constant operation may be stored in the built-in storage container. The fuel is fed automatically from the pellet tank to the grate via a screw conveyor, with the quantity of fuel automatically being adjusted to the relevant heat output.

The internal control unit regulates the ignition phase, the heating phase and the cooling down phase, thereby guaranteeing safe operation of the pellet stove. The operator console, which consists of a display and four function keys, is built into the pellet tank cover.

On the display’s information screen the operator can read the operating status that the stove is currently in, this being displayed as text. Any error messages are shown on the display as text complete with the date and time.

The heating of the air in the room and the creation of comfortable living conditions is mainly achieved by convection. This allows you to quickly warm up even cold

rooms that have been unheated for a lengthy period. The cooler air of the room enters the stove at the bottom of the cladding, is heated and flows out again at the top in the area of the slats. The proportion of radiant heat is given off by radiation in the area of the viewing window of the combustion chamber door and from the stove’s metal surfaces.

2. General instructions, safety instructions

• Before commissioning the pellet stove read the entire installation and operating instructions through thoroughly.

• Only permitted handling gear with sufficient loadbearing capacity may be used for moving your device.

• Your heating device is not suitable for use as a ladder or mounting frame.

• For the installation of your stove, the fire protection authority’s regulations and the local building regulations in force at the installation site are to be observed and you should also discuss this with the district heating inspector. He will also check that the connection of the device to the fireplace is carried out correctly.

• All the checks required by law have been performed on your stove. The mandatory indices regarding technical combustion efficiency and flue gas emissions are observed.

• The pellet stove may be connected to a multiple-use chimney provided that the chimney dimensions permit this according to DIN EN 13384-1 or DIN EN 13384-2. The supply pressure must be at least 6 Pa and should be 15 Pa as a maximum.

•

L The combustion chamber door may be opened

only

for cleaning and maintenance during operating status “Off”. Otherwise it is to be kept closed – even when the stove is not operating in order to avoid affecting other heating appliances and the associated risks.

• An adequate supply of fresh air must be guaranteed to the room where the stove is installed. However, the pellet stove offers you the option of a direct connection to the outside air via a suitable air duct. So operation independent of the air in the room is possible. (See Section 3 “Installation of the pellet stove and connection to the chimney”).

•

L Attention! The pellet stove may not be set

up to be operated jointly with the home’s air

conditioning and ventilation units.

Page 4

• The chimney (fireplace or flue) must be made of stainless steel or ceramics (glazed internally) and suitable for wet operation so that it cannot rot.

• The pellet stove cannot be connected to the mains electricity until it has been correctly connected to the fireplace.

• The pellet stove may not be installed in the open air!

•

L Attention! The mains cable plug must remain

freely accessible after installation.

• The pellet stove may only be operated with standard wood pellets (6 mm diameter). (See Section 7.1 “Fuel”).

• The protective grille located in the pellet container must not be removed.

•

L Attention! The Pelletto stove may only be

operated with the tank cover closed.

• Placing non-heat-resistant materials or objects on the stove or within the specified minimum distances is forbidden. Here please note in particular that during “Standby” operating status, the stove may unexpectedly and unintentionally start heating when the room temperature falls below the desired temperature.

• Never use liquid fuels to ignite the pellet stove or to revive existing embers.

• With the burning up of fuels, heat energy is released, leading to strong heating of the heating device’s surfaces (e.g. doors, door and control handles, viewing window panels, side walls, front wall, flue tubes). Touching these parts without suitable heat protection gloves or a tool is to be avoided!

• The device ignites by itself in “Standby” mode. Because of the heat generated on the panel, make sure that no-one who is unfamiliar with the operation of the pellet stove is unsupervised in the room where it is installed.

• Bring these risks to your children’s and guests attention!

• In particular, any cleaning staff should be informed and instructed regarding the possible unexpected heating up of the stove.

• Placing non-heat-resistant objects on or near the heating device (even when it is cold, since it can ignite again by itself) is forbidden!

• Do not lay any laundry on the stove to dry!

• Clotheshorses for drying clothes and the like must

be positioned at sufficient distance from the heating device – fire risk!

• When operating your heating device, it is forbidden to work with highly flammable or explosive substances in the same room or an adjacent one!

3. Installation of the pellet stove and connection to

the chimney

The packaging on your new pellet stove gives it optimum protection against damage. Nevertheless, damage may have occurred to the stove or to accessories in transit. Please therefore check your stove after unpacking for damage and completeness! Report any defects or anything missing to your specialist stove dealer without delay!

Remark: Combustion chamber cladding that is loose or has come off its fastenings and the like are not defects. (See Section 7.2. “Commissioning your pellet stove”).

The packaging on your stove is by and large environmentally neutral. The timber packaging is not untreated. The timber, the cardboard and the films can be taken without problems to your local recycling centre.

For the correct operation of your pellet stove it is important that it stands horizontally

. The room temperature sensor that is located on the back wall has a length of about 1.5 m and should be positioned hanging free at the back.

Floor protection

The floor is to be protected from the radiant heat from the area of the viewing window (combustion chamber). In addition, for practical reasons associated with cleaning it is recommended that you install your pellet stove on a fireproof base that extends beyond the device at the back and on the sides by at least 5 cm and at the front by at least 50 cm. We have floor protection plates (underlay plates or U plates) in our range of accessories. If required, you may order them from your specialist stove dealer. As an alternative, a tile or stone floor is of course very suitable.

Safety gaps (minimum gaps):

During installation of the stove it is absolutely essential to observe the official fire protection regulations. Ask your district heating inspector about this.

The following must be maintained as the minimum distances from flammable or temperature-sensitive materials (e.g. furniture, wallpaper, wooden cladding) and from loadbearing walls. (See drawing): A 5 cm from the back wall B 10 cm from the side walls and C 80 cm in the direction of radiation.

Figure 2: Safety gaps The chimney (fireplace or flue) must for example be

made of stainless steel or ceramics (glazed internally) so that it cannot rot. This is necessary because of the low temperature of flue gases from your pellet stove. Standard trade flue tubes may be used for the connection to the fireplace. Approved Flex steel flues are also suitable.

Since excess pressure may build up at the smoke outlet because of the way that the pellet stove works with an induced draught fan, all fume outlet pipes as far as the intake to the fireplace must be gas-tight. It is also essential to ensure that the flue tube does not stick out into the open cross-section of the chimney. The use of wall lagging is recommended for the insertion into the chimney. (See Figure 3). With longer flue gas pipework, horizontal sections and constrictions must be avoided and specially insulated flue tubes should be used. Pipework rising in the direction of the chimney is recommended.

Figure 3: Chimney connection 1 = Wall lagging 2 = Gas-tight pipework 3 = Underlay plate

External air intake:

In airtight buildings, whilst the pellet stove is operating, a reduction in the oxygen level in the room where the stove is installed may occur, so adequate ventilation must be ensured. For this the pellet stove offers you the option of operating independently of the air in the room. To do this, connect the air intake elbow located on the back (diameter: 50 mm) to a hose or a similar suitable air duct. The end of the air duct must be located in the open air or in a well-ventilated room within the building. When installing the pellet stove in combination with controlled residential room ventilation, the end of the air intake duct must not be connected to the ventilation system in an adjacent room with the air connection system. To ensure sufficient volume of air intake, the pipe should not be longer than about 3 m and not have too many bends. This pipe should have a

Page 6

minimum diameter of 5 cm. (The bigger, the better). If the pipe goes to the open air, it must end with a downward 90° bend or with wind protection. (See Figure

4).

Figure 4: Wind protection of the air intake pipe

The following table applies to the sizing of the air intake pipe:

Diameter of the intake pipe *

Maximum length *

Max. number of

90° bends 50 mm 0.5 m 1 70 mm 1 m 1

100 mm 3 m 3

*The figures given apply as appropriate. With a flat duct or similar, a suitable cross-section is to be chosen.

If the pipes are narrower than these dimensions, it may be that the volume of combustion air is insufficient. This will result in heavier buildup of clinker in the grate and thereby to safety shutdowns.

Connection to the electricity supply:

Connect the stove to the electricity supply with the mains cable supplied. (See Figure 1).

4. The pellet stove’s functional characteristics

Your pellet stove is designed to operate in such a way as to maintain a constant comfortable room temperature. The generation of heat in the stove is therefore automatically controlled by the desired room temperature (target temperature) set by the operator. Depending on the difference between the target temperature and the current room temperature (actual temperature) the control unit selects output or “Standby” mode in a modular fashion. So the pellet stove guarantees the best possible adjustment of

the combustion behaviour of the pellet stove for the situation in the room where it is installed without constant manual corrective measures.

5. The pellet stove’s operating statuses:

The operation of the pellet stove is characterised by 8 operating statuses: The ignition phase begins if the current room temperature falls below the set target temperature by 1ºC and the stove has cooled down to a temperature of below 80C°.

5.1. Ignition phase

In the “Ignition phase” the grate is filled with a precisely defined quantity of fuel and this quantity of fuel is ignited with a glow igniter.

The “Ignition phase”, which is divided into 10 zones, is ended after reaching a precisely defined temperature on the “flame temperature sensor” and the control unit switches to “Heating Mode” operating status.

The duration of the “Ignition phase” may vary but it is restricted to a maximum length of about 20 minutes.

If during these 20 minutes no flame is formed or the required temperature is not reached at the “flame temperature sensor – flue gas”, a safety shutdown is initiated.

Here the rotation speed of the induced draught fan is constantly measured and checked by means of the rotation speed feedback.

5.2. Heating mode

After successful completion of the “Ignition phase”, the stove automatically switches to “Heating mode” operating status.

In “Heating mode” operating status, the stove’s heat output is adjusted in modular fashion on the basis of the room temperature or the difference between the actual room temperature and the target room temperature.

If there is a great difference between the target room temperature and the actual room temperature, then the stove will operate with greater heat output (maximum 8 kW).

The closer the actual room temperature comes to the target room temperature, the more the heat output of the stove is reduced (minimum heat output = 2.5 kW).

Depending on the required heat output, the relevant quantity of fuel will be supplied at a regular rate via the pellet chute to the grate by means of the screw conveyor.

During the “Heating mode” operating status, the flame or combustion chamber temperature is measured just above the flame by means of a special thermosensor whose signals are processed in the control unit and are the basis

Page 7

for the relationship of the “energy level in the grate” and the combustion air volume taken in, which ensures “ideal combustion” and a high level of efficiency.

During the “Heating mode” operating status, the rotation speed of the induced draught fan is monitored by means of rotation speed feedback and constant comparison between the target and actual rotation speeds.

In the event of a large difference between the actual rotation speed and the target rotation speed, a safety shutdown will be initiated and an error message is shown on the operator console display.

During the “Heating mode” operating status, the maximum and minimum heat output are each controlled by safety limits (maximum and minimum flue gas temperature) i.e. if during the “Heating mode” operating status the maximum flue gas temperature is exceeded or if the flue gas temperature falls below the minimum, a safety shutdown will be initiated.

5.3. Burner test

Every 30 minutes during the “Heating mode” operating status, a burner test is performed.

The burner test is performed regardless of the heat output currently being delivered by the stove.

This process takes about 2 minutes.

5.4. Cooling down

If the set target room temperature is reached i.e. the actual room temperature and the target room temperature match, then the control unit switches to “Cooling down” operating status.

The fuel supply is stopped i.e. the screw conveyor that is located in the screw conveyor tube, stops, the rotation speed of the induced draught fan is regulated to a precisely defined rotation speed and the fuel which is still in the grate is burnt.

The cooling down phase is restricted by timing control (duration about 15 minutes).

After the end of the “Cooling down” operating status, the device switches to “Standby” operating status.

5.5. Standby

There is no combustion process going on in this operating status, all the components, the induced draught fan and the screw conveyor are stopped, the ignition is switched off and the device is in a “waiting position.”

Before the stove can switch back from “Standby” operating status to the “Ignition phase” operating status, two ignition conditions must be fulfilled:

1. The room temperature must be at least 1.0ºC below the set target room temperature.

2. The flue gas temperature measured with the thermosensor must be lower than 70°C.

It is only when both these ignition conditions have been fulfilled that the device switches back from “Standby” operating status to “Ignition phase” operating status.

L Attention!

The device starts by itself in “Standby mode”. Because of the heat generated on the panel, you must ensure that there is no-one who is unfamiliar with the operation of the pellet stove unsupervised in the room where it is installed. Placing non-heat-resistant materials or objects on the stove or within the specified minimum distances is forbidden.

5.6. Safety shutdown (shutdown)

If a fault occurs, regardless of in which operating status or which operating mode, a safety shutdown is initiated.

The safety shutdown process is precisely defined. During the safety shutdown, the components are

switched on or off as follows: Induced draught fan – ON Screw conveyor – OFF Ignition – OFF

The ending of the safety shutdown is temperaturedependent i.e. the “Safety shutdown” operating status is maintained until the stove has cooled down to a flue gas temperature of below 80°C.

Once the safety shutdown is ended, the control unit switches to the “Fault” operating status.

5.7. Faults

The stove can no longer be automatically started up. The operator can see the fault on the display. Once the fault has been properly corrected and the error

message on the operator console has been cleared, the stove may be started up again.

Page 8

5.8. Switching off – operating status OFF

Procedure: Press the left key on the operator console until the information screen appears. Press the right key (Menu), then move the cursor to Operating Mode with the two middle keys – press the right key (Select) – move the cursor to “OFF” operating mode with the two middle keys – press the right key (Save). The stove initiates the Cooling down operating status and can no longer switch to Heating mode by itself, even if the room temperature falls below the set room temperature. During OFF operating status, the operator console and parts of the control system continue to be supplied with power. (About 9 Watts per hour).

5.9. Power cut

The control unit has a backup battery so that the data are retained during a power cut.

A distinction is made between a short power cut and a long power cut.

Short power cut – duration of the power cut shorter than 30 seconds:

Once the electricity supply has been restored, the stove continues its operation from where it was before the power cut.

Long power cut – duration of the power cut longer than 30 seconds:

Once the electricity supply is restored, the stove switches to Safety shutdown operating status.

A small amount of flue gas may escape during a power cut.

5.10. Overheating

If the maximum permitted flue gas temperature is exceeded, a safety shutdown is initiated and the following error message is shown on the display: “Shutdown flue gas temperature in Heating mode too high”. The stove cannot restart its heating mode until the error message has been cleared on the operator console and the desired operating mode has been reset.

5.11. Low temperature shutdown

If during the Heating mode operating status the stove cools down below a minimum temperature, a safety shutdown is initiated and the following error message is shown on the display: “Shutdown flue gas temperature heating mode too low” The stove cannot restart its heating mode until the error message has been cleared on the operator console and the desired operating mode has been reset.

6. Description of operator console keys

6.1. Operator console

As can be seen in the figure, the display is divided into five areas.

7. Operating the pellet stove

The pellet stove may only be heated by adults. Make sure that children are never left alone with the pellet stove. (Do not leave the pellet stove unsupervised for a long period). The pellet stove may only be used in accordance with these operating instructions.

Please observe the safety instructions set out in Section

7.1. Fuel

The pellet stove may only be operated with “pellet” fuel. With this fuel you have chosen CO

-neutral heating for

your home. Pellets are made from wood waste from sawmills and

planing works and from wood collected from forestry businesses. These raw materials are therefore of 100% natural origin and are ground, dried and pressed into “pellet” fuel without the addition of binding agents.

This fuel is standardised (e.g. DIN 5173, Ö-Norm [Eco standard] M 7135, EN 14961-2).

L Important: Your HAAS+SOHN Pelletto pellet

stove may only be operated with standardised wood pellets with a 6 mm diameter.

You can identify good quality wood pellets by eye by: smooth, shiny surface, uniform length, little dust. Wood pellets of lower quality are characterised by: Lengthwise and crosswise cracks, a high proportion of dust, different lengths. Precise quality features may however only be identified with suitable technical analysis equipment. A simple quality test: Put a few wood pellets in a glass of water:

Good quality: Pellets sink Lower quality: Pellets float.

The use of lower-quality or unauthorised fuel adversely affects the operation of your pellet stove and may in addition lead to the lapse of the guarantee and the associated product liability. Unauthorised fuels include woodchips, straw and maize. Burning wood pellets of poor quality leads to shortening of the cleaning intervals and to increased fuel consumption, so the pellet tank has to be filled more frequently.

Wood pellets are packed in plastic or paper sacks. To ensure problem-free combustion of the wood pellets it is necessary to dry the fuel as much as possible and to transport and store it free from dirt. On contact with moisture, pellets swell considerably.

When filling the storage container with wood pellets, make sure that the pellet sacks do not come into contact with the hot surfaces of the stove.

Two kilograms of wood pellets have about the same energy content as a litre of “extra light heating oil.” In terms of volume, 3 m

of wood pellets are equivalent to about 1,000 litres of heating oil. Variations in heat output by the pellet stove are caused not only by the quality of the pellets but also by the raw material of the wood (type of wood).

7.2. Commissioning your pellet stove

The materials making up your pellet stove must gradually get used to the heat generation. By careful warming up you avoid cracks in the combustion chamber plates, damage to the paintwork and warping of materials. So do not set the target temperature too high on the control unit (about 1.5°C to 2°C higher than the current room temperature).

• Before commissioning, remove any stickers and any

accessories from the ash pan and the combustion chamber. This also applies to any transportation/handling securing materials.

• Check that the combustion chamber cladding is

attached to its fastenings. (This might have slipped out

of its position as a result of the transportation or

installation of the stove).

• Check that the combustion pot fits perfectly in its frame.

• Close the combustion chamber door.

• Fill the storage container with standard wood pellets

(Ø 6 mm).

• Insert the mains cable.

• Set the On-Off toggle switch to “1”.

• Once the toggle switch has been set to ON, the

control unit commences initialisation. This process takes a few seconds.

• After initialisation, the Information screen appears – press the right key (Menu) – move cursor to Operating mode – press the right key (Select) – select the desired operating mode with the cursor – press the right key (Save).

Tip!!

Only when commissioning, place about 30 pellets in the burner. This will speed up the ignition process.

General:

If the ignition phase could not be successfully run i.e. no flame generation or the required temperature could not be reached at the flue gas thermosensor, then a safety shutdown is

initiated and an error message generated (“Ignition phase target temp. flue gas not reached – check burner – date and time”).

Correcting the fault: Once the stove has cooled down, empty the burner and, if necessary, clean it. Take care! There may still be residual embers in the ash! Then press the left key on the operator console repeatedly until the error message appears – then press the right key of the operator console (Clear) – now the Info screen appears – press the right key (Menu) – move the cursor to Operating mode and press the right key (Select) – the screen in which the operating mode may be selected appears – select desired operating mode with the cursor and press the right key (Save). The stove begins the ignition phase.

Note: Any smoke generation caused by further drying of the paint stops after a short while. Please properly ventilate the room where the stove is installed. However, the paint does not contain any toxic vapours.

7.3. Selecting the operating mode

The control unit allows easy selection of operating mode from the “Heating” and “Auto” weekly programme modes.

Page 12

7.3.1 “Heating” operating mode

The keys on the operator console are explained in Section 6. In this operating mode the operator may set the desired target room temperature (between 10°C and 30°C) by means of the four operator keys on the operator console.

The stove heats the room to the relevant target room temperature and after reaching this and going through the Cooling down programme it switches to “Standby” operating status.

Whilst the stove is operated in this operating mode, the room is repeatedly heated to the set target room temperature by day and night i.e. during this operating mode, no distinction is made between day and night or any other times with regard to the desired room temperature.

8. Cleaning and maintenance work

The functioning of your device depends to a large extent on regular expert maintenance. Because of the ash accumulation resulting from the combustion of wood pellets, constantly recurring cleaning and maintenance work needs to be carried out. This will permit operation to be as trouble-free as possible. The frequency of maintenance in turn depends to a large extent on the pellet quality (ash content). Quality pellets have a low ash content of about 0.2-0.3%. However, if the ash content is higher (0.5% and over), the interval from maintenance to maintenance is reduced and the accumulation of ash increases by 2 or 3 times. This results in lower heat output and an increased fan rotation speed.

We therefore recommend checking and/or cleaning the flue gas passes after 1,000 kg of pellets at the latest. (See Figure 8 a+d).

L Attention!

Devices that are not maintained in accordance with our specifications must not be operated. Failure to observe this point will invalidate all guarantee claims.

As soon as you detect ash and clinker deposits in the cold combustion pot, it must be cleaned. (See Figures 5 +6). If this is not done, the clinker will continue to accumulate. Then the device will no longer be able to ignite properly. Pellets can pile up in the combustion pot. In extreme cases, this can reach all the way back to the pellet chute. Backfire in the pellet container and smouldering in the pellet tank might possibly result.

This will destroy your device and is not covered in your guarantee.

L Attention!

Before cleaning work starts, the stove must be cooled down, the On/Off toggle switch must be in the “0” position and the mains cable must be disconnected! Once the cleaning work is completed, the correct operating status of the device must be reestablished: Put the combustion pot in correctly, close the combustion chamber door.

8.1 Cleaning the surface

Dirt on the upper surface of the stove may be cleaned off with a damp cloth or if necessary with mild soapy water. You are advised against using corrosive cleaning agents and solvents since these might damage the surfaces.

8.2 Cleaning the glass panel

To clean the viewing panel, you must first open the stove door. Dirt on the glass panel can be removed with a glass cleaner or with a damp sponge on which you have sprinkled some of the wood ash present. (Environmentally friendly). Cleaning the glass panel may only be done with a cooled down stove in the OFF operating mode.

8.3 Cleaning the combustion pot

During operation, deposits may form in the combustion pot. How quickly the combustion pot becomes dirty depends solely on fuel quality. The deposits or encrustations must be removed from time to time.

Page 14

Cleaning the combustion pot may only be done

with a cooled down stove in “OFF” operating mode. Otherwise there is a risk of burns!

To this end the combustion pot must be removed from the stove. Once the combustion pot has been removed, any residual ash that is in the stove underneath the combustion pot must also be removed. After cleaning, the combustion pot is to be put back into the right position in the burner seat. Check the correct seating of the combustion pot again so as to avoid poor seals.

A visual check of the dirt on the burner and the combustion chamber for combustion residues must be carried out by the operator at regular intervals!!!

Figure 5: Burner dirty

Figure 6: Burner clean

The cleaning intervals for the combustion pot and the glass panel depend directly on the quality of the wood pellets (high ash content) and may vary between a few hours of combustion and several days.

8.4 Removing the ash from the combustion chamber

To thoroughly clean the ash out of the combustion pot and the combustion chamber, the pellet stove must be in a cooled down condition and in the OFF operating

mode.

Procedure:

Press the left key on the operator console repeatedly until the Info screen appears – then press the right key (Menu) – with the two middle keys move the cursor to Operating Modes – press the right key (Select) – with the two middle keys move the cursor to OFF – press the right key (Save) - the stove begins to cool down. Once the stove has completely cooled down, cleaning work can begin.

Attention!! The stove’s Cooling down programme is ended after about 15 minutes. The stove may still be hot after the end of the cooling down phase. Do not start cleaning until the stove is completely cooled down! “Risk of burns!”

The frequency of ash removal depends directly on the quality of the wood pellets used. We recommend removing the ash from the combustion chamber with an ash vacuum cleaner.

8.5 Cleaning the pellet container

Heat the pellet stove until the storage tank is completely empty. Then the protective grille (2) in the pellet tank may be removed. Then clean the tank and the intake of the screw conveyor housing with a vacuum cleaner. After cleaning, it is essential to put back the protective grille. When doing this, make sure that no screws fall into the pellet tank so as to avoid consequential damage to the screw conveyor.

Figure 7: Pellet tank 1 = Pellet tank cover 2 = Protective grille 3 = Tank cover seal

Page 15

8.6 Cleaning the flue gas passes and the flue tubes

Normally it is sufficient to clean the flue gas passes and the flue tubes once a year. First pull the stove away from the wall so as to create enough room to work at the back. To clean the flue gas passes, proceed as follows:

Disconnect the flue baffle (1) from the guide by lifting it. Draw the right cladding (2) down out of the guide and place it down in the ash space. Then the flue baffle can be removed and the upper part of the combustion chamber can be cleaned. (See Figure 8a).

Figure 8a: Removing the flue baffle Then remove the right side wall. This is fixed with

screws (1) at the back and at the front with 3 connectors.

Remove the screws from the back and pull the side wall off

sideways. (See Figure 8b).

Figure 8b: Removing the side wall Undo the screws and remove both the covers of the

openings. Now you can clean the exposed insides of the flue gas passes. (See Figure 8 c+d).

After completion of the cleaning make sure that when putting back the covers, the seals are seated

in the right positions. It is essential to replace defective seals.

Figure 8c: Cleaning covers

Figure 8d: Cleaning covers open

8.7 Cleaning the induced draught housing and fan

This housing is made accessible for cleaning by undoing the 4 nuts shown in Figure 9. (See arrows). Remove the induced draught motor by pulling it out. Now clean the flue gas passes, the induced draught fan and the flue tubes with a brush and an ash vacuum cleaner. Then reassemble the components in reverse order. Make sure that the seal is seated in the right position again. It is essential to replace defective seals. Make sure of the electrical connections on the fan motor and their correct positions.

Figure 9: Induced draught fan

Page 16

9. Description of the components

9.1 Storage container (pellet tank)

17 kg of wood pellets can be stored in the storage container. This quantity permits constant operation for up to 30 hours.

9.2 Screw conveyor motor / screw conveyor

The screw conveyor motor drives the screw conveyor. This delivers the wood pellets from the storage container to the combustion chamber (combustion pot). The screw conveyor motor’s rotation speed is regulated and it therefore delivers the required supply quantity to the modular heat output (2.5 kW to 8 kW). If the screw conveyor becomes blocked because of foreign bodies in the wood pellets or a too-high level of fine particles, it can often be unblocked by simply moving the screw conveyor motor housing back and forth. To do this, you must first remove the back wall by pulling it down. (See Figure 1, no. 7).

L Attention!! First pull out the mains

plug!

Any fault with the screw conveyor motor is detected by the control unit and this initiates the cooling down phase.

Figure 10: Screw conveyor motor

9.3 Combustion pot with tray:

The combustion pot is made of high-grade stainless steel. The special design of the combustion pot guarantees clean and extremely efficient combustion of the wood pellets.

Figure 11: Combustion pot correctly installed

9.4 Electric ignition

The built-in electric ignition is made of stainless steel (see Figures 13+14) and generates the ignition temperature required to ignite the wood pellets. The period during which ignition is activated depends on how quickly the required flame temperature is reached so that the system can switch from the Ignition phase to Heating mode. The average ignition glow time is 10 to 12 minutes (depending on pellet quality). The ignition phase is restricted to a maximum time of 20 minutes and therefore the maximum ignition glow time is also restricted to 20 minutes. Depending on the fuel quality, the flame should be formed in 3 to 7 minutes.

9.5 Control unit

The microprocessor control unit ensures safe, automatic operation of the pellet stove. The control unit controls the interaction of the components e.g. induced draught fan, screw conveyor motor, flame temperature sensor, room temperature sensor etc..

The pellet stove’s electrical fuses are incorporated into the control unit. To change these fuses you must remove the left side wall.

9.6 Operator console

The operator console is built into the pellet tank in such a way that the display with its four function keys is easily accessible. All the parameters necessary for the operation of the stove can be set with this operator console. Access to these parameters is divided into two levels. The first level is intended for the stove operator. The second level is intended for customer service and may only be accessed by inputting a special access code. Description of the first level – the one for the operator: The operator can make the following adjustments with or read the following information on the display of the operator console:

• Start or stop the device

• Set the desired target room temperature (in

“Heating” operating mode).

Page 18

• Select “Heating” or “Auto” operating mode

• Set up a weekly programme with the desired

target room temperature and the associated switch on and off times in “Auto” operating mode

• Read off the relevant operating mode and the relevant operating status which the device is currently in and the date and time

• Read every error message shown as text and number

• Make the selection of language for the menu on the operator console.

Figure 15: Operator console

9.6.1 Backlighting

The backlighting of the display is switched off 5 minutes after the operator console was last operated.

9.6.2 Activating the backlighting

The backlighting is switched on by pressing any key. It is only after the backlighting is activated that the function keys are active. The backlighting is also activated by any error message generated.

9.7 Induced draught fan with rotation speed feedback

The induced draught fan generates low pressure in the combustion chamber and thereby supplies the required volume of air for combustion to the combustion chamber or through the combustion pot. The induced draught fan is equipped with rotation speed feedback. This permits detection of any difference between the target and actual operating status and countermeasures to be taken or, in the case of greater differences, permits the stove to be shut down (safety shutdown).

9.8 Flame or combustion chamber temperature sensor (combustion chamber thermosensor)

The flame temperature is measured in “Heating mode” operating mode. The flame temperature measured is an indicator of the energy level in the grate and hence the basis of the air volume required for the combustion of the energy level located in the grate. Here the ACTUAL flame temperature is compared with the TARGET in combination with the processorregulated control unit and the appropriate combustion air volume required for the combustion of the energy level in the grate is supplied by means of the induced draught fan.

9.9 Flue gas thermosensor

The flue gas thermosensor is located on the housing of the induced draught fan and protrudes into the flue gas duct across the direction of the flow of the flue gas, where the flue gas flows around it, and thus measures its temperature and temperature change. (See Figure 10). With the thermosensor, the temperature and its change can be measured directly (accurate to about 2ºC) in the flue gas and so be accessed for the control unit and regulation.

9.10 Room temperature sensor

The room temperature sensor measures the ACTUAL room temperature in the area of the stove. The room temperature sensor is an instrument for the TARGET – ACTUAL comparison between the TARGET room temperature and the ACTUAL room temperature and is therefore the basis for the specification of the required heat output for the stove.

9.11 OC – Overheat cutout

The overheat cutout sensor is located on the screw conveyor tube. When a certain temperature is reached, the OC is triggered independently of the control unit and it cuts the stove off from the electricity supply. (Thermo protection).

9.12 Combustion chamber cladding

The combustion chamber is clad on its three casing surfaces, the left side wall, the right side wall and the back wall with the material Vermiculite.

Figure 17 : Combustion chamber

1 = Combustion chamber cladding, left 2 = Combustion chamber cladding, back 3 = Combustion chamber cladding, right 4 = Flame temperature sensor 5 = Bottom temperature sensor 6 = Combustion pot 7 = Combustion tray 8 = Pellet chute 9 = Door contact switch

9.13 Flue tube connection

The diameter of the flue elbow is 80 mm. The flue tube must be connected to the fireplace in accordance with official regulations. For questions in connection with this, please contact your local chimneysweep. Because of the way the pellet stove works with a combustion air fan, high pressure is generated at the flue gas outlet and possibly in the fireplace. This means that the flue gas pipes must be designed to be gas-tight as far as their entry into the fireplace.

9.14 Mains cable and master switch

Important! The electricity supply to the pellet stove must always be present! No time switches or other electric switches may be inserted in or before the stove’s mains cable. Otherwise your pellet stove may suffer damage. The master switch for your pellet stove is located next to the mains cable socket.

20. “Clean combustion chamber” function instruction

The display on the operator console starts flashing. (The backlighting switches on and off and the “Clean combustion chamber” instruction appears). The instruction to clean the combustion chamber refers not just to the cleaning of the burner but also to the cleaning of the entire combustion chamber with an ash vacuum cleaner.

The process of the “Clean combustion chamber” function looks like this: The entire combustion chamber is to be cleaned with an ash vacuum cleaner at intervals of no longer than 50 operating hours. The number of operating hours is measured within the control unit during Heating mode. After 50 operating hours, the display on the operator console starts flashing. This flashing is an instruction not to defer cleaning the combustion chamber beyond this time. However, this instruction to clean the combustion chamber (display flashing) does not trigger an error message during Heating mode. But after the display has started flashing, if the stove switches

Page 25

back to “Standby” mode, the stove can no longer be automatically ignited before the combustion chamber has been cleaned. To clean the combustion chamber, the stove has to be switched to “Off” operating status. If the combustion chamber is now cleaned, then the “Clean combustion chamber” error message will thereafter be cleared automatically. A precondition for the automatic clearance of this error message is that the combustion chamber door is open for longer than 60 seconds in “Off” operating status. This time is required for cleaning the combustion chamber including the burner thoroughly with an ash vacuum cleaner. If the door is open longer than 60 seconds in “Off” operating status, then the operating hours counter, which is responsible for the “Clean combustion chamber” instruction, is automatically reset to zero. This reset of the operating hours counter occurs even if the cleaning of the combustion chamber is performed before the 50 operating hours have run provided that the stove is in “Off” operating status and the door is open for longer than 60 seconds during cleaning.
