High-quality cast iron and the vermiculite inner cladding ensure an optimum heat output. The elongated ue channel in the stove ensures that the soapstone is optimally heated when the stove is used. The heat retention property of the soapstone is such that most of the thermal energy is retained in the soapstone mass, which continues to radiate heat long after the re has gone out. Installation It is common practice for the dealer where you purchased your stove to also take care of installing it. If this is not the case, please ensure that the installation is done by a certied installer. A certied installer can also give you the right advice about the ue tube to which the stove must be connected. Connecting wood-burning stoves by unqualied persons is prohibited, in which case we cannot give any guarantee about proper functioning of your stove. Please bear the re safety in mind when installing the stove. See also page 25. It is not allowed to have wood-burning stoves connected by unqualied installers. In such case we cannot give any guarantee that the Olaf Eco will work properly. The wood-burning stove is suitable as an extra heat source and does not replace your principal heating device. Lighting the stove Lighting your stove early in autumn or late in winter When the external and internal temperatures do not dier much, a proper chimney draught is a real challenge. You can help chimney draught get started early in autumn or late in winter by burning some wood while keeping all air inlets maximally open. An abundant air supply speeds up quick heating which in turn increases the draught in the chimney. Lighting up the stove with only a little wood prevents smoke from streaming into the room but be sure that the valve is not completely closed.

The stove will become very hot when you light it and will need at least a couple of hours to cool o. Don’t touch the stove without protection during ring and during cooling o. Handle the stove always with a glove to avoid getting serious burns.Before lighting the re, you must clean away any deposits on the window pane with a piece of paper towel. The same paper can be used for lighting the re.Open the combustion air inlet . Open the slide to its maximum before lighting the stove. Open the ue gas regulator in the ue duct . Then open the door and put some balls of paper or relighters in the stove and place some wood kindling on top. Light the kindling and leave the stove door ajar (for 3 to 5 minutes) for extra air supply and enhancing chimney draught. Once the kindling has caught re you can add extra wood. (Put the logs loosely on the re so that the ames can catch on all around). Close the ue gas regulator once the stove has the right temperature The ue gases are then guided along the soapstone on the inside. Reloading wood To prevent fumes from entering the room while reloading the wood make sure to open the regulator in the ue duct rst. After you’ve closed the door you can close the regulator again. Air valve The air valve has 3 positions:1. Opened all the way: the primary and secondary air supply is open.

2. Pressed until the rst click is heard: only the secondary air supply is open and the stove will produce the

highest yield while the glass cleaning system works optimally.3. Pressed until the second click is heard: everything is closed, and the re will go out slowly.It is prohibited to light the stove with liquids like petrol or spirits. Do not have the cooker hood on in the room where you operate your stove.Never touch the varnished parts when you heat your stove. Lighting the stove for the rst time Newly-built house or recently renovated? It is advisable to wait six weeks before lighting the stove in a newly-built house that has recently been completed, or in a space that has recently been renovated drastically. The walls and ceilings still contain gases, softeners and moisture from plasterwork or paint. The warm air-streams may discolour the dust particles in the space which may stick to walls and ceilings. Even the moisture in the walls and ceilings will become warm and may cause yellow stains. Anneal procedure for soapstone The warranty does not cover any damage caused by not complying with the anneal procedure set out below. The stove is only suitable for burning wood. Please see the chapter on ´Fuel´ on page 20.• Open the air valve

• Open the ue regulator by pulling the handle on the left back to the left .

• Put two relighters in the middle of the re plate

• Arrange a pyramid of 8 to 10 pieces of kindling measuring about 3 cm thick and 25 cm long

• Light the relighters

• Leave the door slightly ajar

• Once the stove is burning and the condensation has disappeared from the glass pane, you can close the door

• Once the stove is burning you can close the ue gas regulator by pulling the left-back handle to the right.

• Do not refuel the stove but leave the stove to die and cool down to room temperature

• Repeat this procedure three times

• Repeat the above steps again but rell the stove with 1 kg of wood and then let the stove die again.

• Repeat this procedure three times. When you light the Olaf ECO for the rst time, the hearth must still ‘anneal’ and temper itself. The unit has a heat resistant lacquer which must burn in the stove at temperatures above 400 °Celsius. This will happen during the rst few times of lighting the stove and temperatures rise to 600 °C. Though this may give an unpleasant smell, it is otherwise harmless. Air the room well when the stove is burning. Make sure that any cooking hood in the same space is not turned on when the stove is burning; a cooking hood extracts the combustion air that the stove needs. Some deposit may form on the glass panes of the stove when you ‘anneal’ your hearth. You can easily remove this deposit with a damp cloth after the stove has cooled down. You can also use some cleansing agent for ceramic rings. Please make sure you do not leave any nger marks on the clean glass. Finger marks burn into the glass and cannot be removed later. It is prohibited to light the stove with liquids like petrol or spirits. Do not have the cooker hood on in the room where you operate your stove. Never touch the varnished parts when you heat your stove. Avoid nger marks Do not touch the glass of the stove with your ngers. Finger marks will burn into the glass and cannot be removed later. Discolouration of walls, ceilings and grates The walls, ceilings and grates may show some discolouration after lighting your hearth. This is caused by the dust particles that burn in the convection cover. This is a natural process for which WANDERS cannot be held responsible. To minimize discolouring we refer to the advice given for atmospheric hearths. Your installer can give you more information about this. Fuel Wood Drying time Fir, Poplar 1 year Lime, Willow, Spruce, Birch, Ash, Alder 1,5 years Fruit trees, Beech 2 years Oak 2,5 years The stove only burns on wood. Do not put more than 3 to 4 kg of fuel in the stove at the time. Always use clean and cut logs, which have suciently dried. Please see the above list for drying times. Wet wood does not burn well and gives heavy smoke emission. It may blacken the glass pane of your stove with soot and build up smut in the ue pipe. This may increase the risk of chimney re.

Fresh, moist wood contains about 50% moisture. Cleaved wood still contains 20% moisture after drying it for a year and moisture percentage will be decreased to 12 to 15% after drying it for two years. Dry wood gives nice ames and little or no smoke, and the re will crackle when burning. Wet wood makes a hissing sound, gives much smoke and only small ames which will considerably dampen the pleasure of burning your stove and the heat output. Do not put any paran-containing logs in your stove. When the door is closed, the high heat will melt the paran from the logs too quickly. The polluted ue gasses which consequently develop will deposit on and burn in the glass of your stove and cannot be removed later. Do not use any wood that is painted, impregnated, glued together or processed in any other way. The ue gases are very harmful to the environment and may aect your stove. It is also prohibited to burn plastics and other waste matter due to poisonous smoke development. Wood species and storage You can use all kinds of woods as fuel as long as it is clean, split and dry. Hardwood like oak, beech and birch burn slowly, give o much heat and form charcoal easily. Softer woods like spruce, r and poplar give more ames but less heat and less charcoal. The best place to store timber is in a windy spot but sheltered from the rain. This is how the logs can dry in a natural way. Pile the logs on an old pallet or a frame to let the wood dry from underneath and to prevent the lower logs from being in contact with water. The best way to burn your stove All WANDERS’ stoves are designed so that they give a maximum output. A well-lit wood-burning stove can produce a yield of about 85%. This means that you need less wood for the same amount of heat. Moreover, a well-lit stove produces less smoke pollution. Below are a few tips to give you optimum pleasure:

• Always burn your stove with its door closed; this will improve the output within 8 to 10 times. When the door of the stove is open, the chimney will draw more air than is needed for proper combustion. The relatively cold air will cool the re. It will also preclude re damage by any sputtering sparks, especially from softwood.

• Do not put more than 3 logs on the re at one time. Too much fuel at one time thwarts ecient combustion and burdens the environment unnecessarily.

• Ventilate the space well when you have the stove on. A crackling re has a minimum air consumption of 25 cubic metres an hour. Never put on your cooking hood when you have a stove burning in the same space.

• Be careful with lighting the stove when it is foggy or when there is no wind outside. There is hardly any draught in the cold chimney when the weather is calm. Since smoke is heavier than air there is the chance of smoke streaming into the room. In foggy weather, the smoke from the chimney (outside) cools quickly and may descend and become a nuisance in your neighbourhood.

• Don’t smother the re suddenly with water, but let it burn out. The materials inside the stove may deform or crack as a result of sudden or great dierences in temperature.

• Avoid loading too much fuel into the stove. To much heat can be produced and may damage the stove permanently. Chimney and ue The chimney is the most important part of your wood-burning hearth. When the chimney is right it will not distribute any smoke into your room, leave any deposit on the glass pane or create bad combustion. Before starting the installation of the stove, your installer or a qualied chimney sweep must check whether the chimney ue has a diameter of at least 150 millimetres over the entire length, and whether the channel is clean, smooth and leak-proof.

!22 Chimney with a proper draught Warm air wants to ascend. This is the principle of every chimney. It helps when the wind near the chimney mouth draws the air from the chimney. Fall wind may give the opposite e ect and blow the air back into the chimney. Relatively cold foggy air may thwart proper draught in your chimney as does a long ue pipe with a rough inside and many bends. If the natural draught in your chimney is poor your installer can give you information about using a ventilator for your ue tube. What to do in case of chimney re In case of chimney re, immediately close the shut-o valve in the chimney and all air supply ducts. Call the re department. After the re is extinguished, the chimney and the stove must be inspected again by your installer. Maintenance Small maintenance

• Remove the cooled-down ash from the stove two or three times a week. It is advisable to use an ash bucket.

• It is advisable to leave an ash layer of two to three centimetres on the re plate. It will protect the material.

• Clean the exterior of the stove with a soft cloth that does not give o u . Do not use any aggressive cleansing agents or abrasives.

• Do not use any water because of the soapstone

• Clean the cold glass pane with a cleaning agent for ceramic cooking rings. Do not touch the clean glass with your ngers. Finger marks burn into the glass. Do not use any aggressive cleaning agents or abrasives to maintain your stove. When the stove is not used

• Leave the air valve open during the summer period. This creates an air ow and any humidity will be drawn out of the stove.

• Clean the stove after the season. Don’t forget the elongated ue channel. Yearly maintenance

• Have your chimney properly cleaned by a quali ed chimney sweep every year; this is for safety reasons and any re insurance.

• Have the valves and/or aps checked for their functioning.

• Have the sealing of doors and glass panes checked for wear and tear. Safety A WANDERS wood-burning stove is a comfortable and safe heat source in your home. Fire safety starts with proper installation and a ue tube that is in good working order. That is why your installer must adhere to the installation requirements as given in page 24 and further. To burn your stove safely, the following points are important:

1. Burn your stove as much as possible with its door closed; it will improve the output and is much better for

2. Prevent small children or the in rm from getting too close to a burning stove, and never leave them alone

in the room when the stove is burning. You could use a re-screen.

3. Do not pour combustible liquids or put combustible

materials on the stove, as it may damage the replace beyond repair.

4. Never place the stove in front of a wall covered

with combustible materials (such as wallpaper).

5. The Olaf Eco wood-burning stove should never be

Installation Instructions Olaf Eco The Olaf Eco is tested in accordance with the international EN 13240 standardization, and has an extra additional standardization for optimally environment-friendly heating devices related to ue gases (Section 15a B-Vg. Des BmfWA). The stove can be connected to a ue tube to which several stoves are connected. The ue tube has a diameter of 150 millimetres. The heating device must be placed by an acknowledged installer and according to the installation instructions given below. The national and local rules and regulations for placing and using wood-burning stoves are equally applicable. WANDERS does not give any guarantee if the Olaf Eco is connected or installed incompletely or incorrectly.It is not allowed to place the stove in:• Arcades and corridors accessible to the public.• Stairwells, except in buildings with no more than 2 dwellings.• Spaces where highly ammable or explosive materials are used.

• Spaces where an exhaust system is used or where a mechanical exhaust system is placed, except when the air supply is taken directly from outside to assure a hazardless combustion. Preparation The chimney ue Before placing the stove you must observe the following points:
• If the stove is connected to an existing chimney, you must rst have the chimney professionally cleaned and checked by a qualied chimney sweep company. Any cut-o valves or stop valves must be removed. • The ue tube of the stove must be connected with the chimney without diversions.• The underpressure in the chimney must be at least 12 Pa or 0.12 mbar.• The chimney ue must always end up in outlet area 1 (see the drawing below)
• At the time of placing the stove, the chimney ue must be clean, leak-proof and without obstructions, and must have a diameter of 150 mm. • Any bends in the ue tube must not exceed 45 degrees.• Ensure that the chimney tube can discharge the ue gases adequately, properly and safely.

Fire Safety For reasons of re safety is it important to observe the instructions below before installing the stove.

1. If the oor around the stove is made of combustible material, you must use a oor slab. The oor slab must

measure at least: - 50 cm from the stove on the front side of the door - 30 cm from the stove on the sides of the door.

2. Keep at least a distance of 80 cm between the stove and combustible objects such as curtains, wooden

objects (cupboards and paintings) and glass objects. Keep the same distance from the ue tube.

3. Wooden construction parts within the radiation range of the stove (80 cm from the exterior of the stove)

must be covered with reproof material.

4. If the ue tube goes through a ceiling and/or roof that consist of ammable materials, the ceiling and the

roof must be covered with reproof materials all around (about 80 cm). Pay also attention to joisted oor layers and any electric wiring.

5. Keep a distance of at least 50 cm (in all directions) between the stove and supporting steel construction

6. Shield o all combustible materials within a radius of 80 cm from the stove openings with non-combustible

7. Never cover the stove and ue pipes with combustible material (e.g. paper covering).

8. The wall behind the stove must consist of, or be insulated with, re-proof materials. The insulation material

must resist a temperature of 700 °C and have a density of 80 kg/m3. Please see for insulation materials table page 29).

9. Avoid heat transmission when placing the stove. Heat transmission of a burning stove can penetrate the

wall and even cause re damage on the other side of the wall. Prevention is better than cure. Installation The Olaf Eco stove is tested in accordance with the international EN 13240 standardization and has an extra additional standardization for optimally environment- friendly heating devices related to ue gases (Section 15a B-Vg. Des BmfWA). The stove can be connected to a ue tube to which several stoves are connected. The ue tube has a diameter of 150 mm. The heating device must be placed by an acknowledged installer and according to the installation instructions given below. The national and local rules and regulations for placing and using wood-burning stoves are equally applicable. WANDERS does not give any guarantee if the Olaf Eco is connected or installed incompletely or incorrectly. Supply of combustion air The stove must have enough supply of fresh combustion air. If necessary, make an extra air supply opening. An extra opening for air supply is always required if:

• the house has a heat recovery system.

• the space where the stove is placed has a central exhaust system.

• there is a cooker hood in the same space. The illustrations give the connections for external air supply.

!26 Connecting the hearth Check whether the oor on which the stove is placed can carry this weight without problem. The Olaf Eco weighs around 375 kg’s. You must follow the directions given in the previous chapter on ‘Preparation” before installing the stove. Please mind your back and the oor during installation!

1. Connect the Olaf ECO to an existing chimney.

2. The under-pressure in the ue tube must be 10 to 12 Pa (0.1 to 0.12 millibars).

3. Take precautionary measures against re (see points 1 to 9 on page 25)

4. Place the stove at the selected place.

6. Place the pipe between the stove and the outlet channel. Connect a Ø 150 mm tube to the coupling unit

(the mouthpiece) in the straightest possible line from the stove to the chimney. The tube must be made of steel with a thickness of at least 2 mm. Please keep in mind that the tube will expand in the length by about 1 cm per meter, and verify that the outlet is not jammed between the mouthpiece and the ceiling. Attaching the soapstone The soapstone panels must be mounted carefully to avoid damage. Please mind your back.27
