Your Square stove at a single glance The wood-burning stove is suitable as an extra heat source and does not replace your principal heating device. Lighting the stove The stove will become very hot when you light it and will need at least two hours to cool off. Don’t touch the stove without protection during firing and for two hours after. Handle the stove always with a glove to avoid getting serious burns. The Square 60 The Square is a combination of comfort and efficient heat emission. The large glass panes allow emission of the heat from the stove directly to the environment to make your room instantly comfortable. The built-in flue gas deflector ensures circulation of flue gases in the interior parts. Combined with the extra after-burning, it means that the flue gases have better combustion and reduce the burden on the environment. You can regulate the intake of combustion air with the integrated air slide valve and adjust the intensity of the fire and the output of your stove. Before lighting the fire, you must clean away any deposits on the window pane with a paper from a kitchen roll. The same paper can be used for lighting the fire. Open the combustion air inlet. Open the slide to its maximum before lighting the stove. Then open the door Installation It is common practice for the dealer where you purchased your Square stove to also take care of installing it. If this is not the case, please ensure that the installation is done by a certified installer. A certified installer can also give you the right advice about the flue pipe to which the stove must be connected. Connecting wood-burning stoves by unqualified persons is prohibited, in which case we cannot give any guarantee about proper functioning of your Square stove. Please bear the fire safety in mind when installing the stove. See also page 21. and put some balls of paper or firelighters 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 fire you can add extra wood. (Put the logs loosely on the fire so that the flames can catch on all around). How the air valve works The air valve has 3 positions: Lighting your stove early in autumn or late in winter When the external and internal temperatures do not differ much, a proper chimney draught is a real challenge. You can help chimney draught get started 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.

Opened all the way: the primary and secondary air supply is open. Pressed until the first click is heard: only the sec- Avoid finger marks Do not touch the glass of the stove with your fingers. Finger marks will 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. Lighting the stove for the first time 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. When you light the Square for the first 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 first few times of lighting the stove and temperatures rise to 600 °C. Though this may give an unpleasant smell, it is otherwise harmless. It is advisable to keep the stove burning with limited fuel for at least 6 hours when lighting the stove for the first 4 or 5 times. Air the room well when the stove is burning. Make sure that any cooking hood 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 finger marks on the clean glass. Finger marks burn into the glass and cannot be removed later. 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. Fuel: wood Wood species Fir, Poplar Lime, Willow, Spruce, Birch, Ash, Alder Fruit trees, Beech Oak Drying time year years years years The Square only burns on wood. Do not put more than 3 kg of fuel in the stove at the time. Always use clean and cut logs, which have sufficiently 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 flue pipe. This may increase the risk of chimney fire. 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 flames and little or no smoke, and the fire will crackle when burning. Wet wood makes a hissing sound, gives much smoke and only small flames which will considerably dampen the pleasure of burning your stove and the heat output. Do not put any paraffin-containing logs in your stove. When the door is closed, the high heat will melt the paraffin from the logs too quickly. The polluted flue 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 off much heat and form charcoal easily. Softer woods like spruce, fir and poplar give more flames 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.

ondary air supply is open and the stove will produce the highest yield while the glass cleaning system works optimally. Pressed until the second click is heard: everything is closed, and the fire will go out slowly. Chimney and flue 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 flue gases are very harmful to the environment and may affect your stove. It is also prohibited to burn plastics and other waste matter due to poisonous smoke development. 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 75%. 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: t "MXBZT CVSO ZPVS TUPWF XJUI JUT EPPS DMPTFE UIJT 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 fire. It will also preclude fire damage by any sputtering sparks, especially from softwood. t %POPUQVUNPSFUIBOMPHTPOUIFmSFBUPOFUJNF5PP much fuel at one time thwarts efficient combustion and burdens the environment unnecessarily. t 7FOUJMBUFUIFTQBDFXFMMXIFOZPVIBWFUIFTUPWFPO A crackling fire 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. t #F DBSFGVM XJUI MJHIUJOH UIF TUPWF XIFO JU JT GPHHZ 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. t %POUTNPUIFSUIFmSFTVEEFOMZXJUIXBUFS CVUMFUJU burn out. The materials inside the stove may deform or crack as a result of sudden or great differences in temperature. What to do in case of chimney fire. In case of chimney fire, immediately close the shut-off valve in the chimney and all air supply ducts. Call the fire department. After the fire is extinguished, the chimney and the stove must be inspected again by your installer. The chimney is the most important part of your woodburning 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 qualified chimney sweep must check whether the chimney flue has a diameter of at least 150 millimetres over the entire length, and whether the channel is clean, smooth and leak-proof. 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 effect and blow the air back into the chimney. Relatively cold foggy air may thwart proper draught in your chimney as does a long flue 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 flue tube.

Guarantee Safety A WANDERS wood-burning stove gives you a comfortable and a safe source of heat in your home. Fire safety starts with a proper installation and a properly working flue tube. Your installer must therefore comply with the installation instructions as listed on page 21 and further. To burn your stove safely, the following points are important:

1. Burn your stove as much as possible with a closed

door; it increases the output and is better for the environment.

2. Prevent small children or the infirm from getting

too close to a burning stove and do not leave them alone in the room when the stove is burning. You could use a fire-screen.

3. Do not pour or put combustible liquids and materials in the stove, as it may damage the fireplace

4. If the floor around the fireplace is made of combustible material you must use a floor slab. The floor

slab must have a minimum size of: - 50 cm measured from the fireplace on the front side of the door: - 30 cm measured from the fireplace on all sides from the door:.

5. Do not place any combustible materials, such as

curtains, wooden objects (cupboards, paintings) close to the fireplace or the flue tube. A minimum distance of 80 cm measured from the exterior of the stove and the flue tube is required.

6. Never cover the chimney breast or mantelpiece

with combustible material (e.g. paper covering).

7. Please bear in mind the points of the section on ‘the

best way to burn your stove’, on page 18.

If the floor around the stove is made of combustible material, you must use a floor slab. The floor 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. 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 flue tube. Wooden construction parts within the radiation range of the stove (80 cm from the exterior of the stove) must be covered with fireproof material. If the flue tube goes through a ceiling and/or roof that consist of flammable materials, the ceiling and the roof must be covered with fireproof materials all around (about 80 cm). Pay also attention to joisted floor layers and any electric wiring. Keep a distance of at least 50 cm (in all directions) between the stove and supporting steel construction parts. Shield off all combustible materials within a radius of 80 cm from the stove openings with non-combustible materials. Never cover the chimney breast with combustible material (e.g. paper covering). The wall behind the stove must consist of, or be insulated with, fire-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 24). Avoid heat transmission when placing the stove. Heat transmission of a burning stove can penetrate the wall and even cause fire damage on the other side of the wall. Prevention is better than cure. Installation The Square is tested in accordance with the international EN 13229 standardization, and has an extra additional standardization for optimally environment-friendly heating devices related to flue gases (Section 15a B-Vg. Des BmfWA). The stove can be connected to a flue tube to which several stoves are connected. The flue tube has a diameter of 150 mm. Supply of combustion air The stove must have enough supply of fresh combustion air. If necessary, make an extra air supply opening as close to the stove as possible to avoid draught. An extra opening for air supply is always required if: t UIFTQBDFIBTBIFBUSFDPWFSZTZTUFN t UIFTQBDFIBTBDFOUSBMFYIBVTUTZTUFN t UIFSFJTBDPPLFSIPPEJOUIFTBNFTQBDF The air supply opening must be closable if it goes through a fire-resistant wall. When there are several combustion devices in the same space there must be enough air openings to guarantee proper combustion. Fans (optional) The fans can’t be placed after the stove has been installed. When fans were ordered they will be installed in the factory. Always connect the fans to an earthed wall socket. Moreover there must be the possibility to disconnect the stove from the electricity supply any service or maintenance. When starting the fans, they will start with their fastest speed, you can regulate the speed of the fans with the knob on the left side. Please be aware that the fans will produce noise. All efforts are made to reduce this noise as much as possible. When refuelling the stove it’s advised to turn the fans off preventing the smoke from being drawn out of the stove. The technical specifications from the fans and the control unit are as follows: Control unit: Voltage Size (L x W x H) 230V / 50Hz 75 x 26 x 20 mm Fan: 230V ~ 50Hz 120 mA 20W Connecting the stove The Square is a heavy insert. Check whether the floor on which the stove is placed can carry this weight without problem. You must follow the directions given in de previous chapter on ‘Preparation” before installing.
