The large glass panes allow emission of the heat from the stove directly to the environment to make your room instantly comfortable. The integrated ue gas deector ensures that extra heat is taken from the ue gasses, which makes that the stove radiates more warmth. And with the integrated air slide valve you can regulate the intake of combustion air and intensify or moderate the intake of oxygen and consequently the output of your stove. The extended ues in the stove ensure that the stove is optimally heated and that less heat is lost. Installation It is common practice for the dealer where you purchased your Square stove to take also 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 Square stove. Please bear re safety in mind when installing the stove. See also page 23. The wood-burning stove is suitable as an extra heat source and does not replace your principal heating device, such as your central heating system. 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 challenge. Early in autumn or late in winter 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.

Lighting the stove The stove will become very hot when you light it and will need at least two hours to cool o. Do not touch the stove without protection during ring and for two hours after. Handle the stove always with a glove to avoid getting serious burns.Before lighting the stove, wipe o any deposit on the glass with a tissue or soft paper; you can use this paper for lighting the re. Slide the valve in the ue gas pipe open. Slide the air slide valve to the maximum position before lighting the re. Shove the ‘ECO’ slide all to the left. Open the door, put some balls of paper or some relighters inside the stove, and place some wood kindling on top. Light the kindling and leave the door ajar (3-5 minutes) to let in extra air and to boost the draught in the chimney. You may add extra wood when the kindling is burning. (Try putting the wood loosely in the re to encourage the ames to go around the logs.Once the stove is burning, you can close the non-return valve by sliding it to the right in the “eco” position. The ue gases are now led via the ue gas tubes. Operation of the air supply The air inlet valve has 3 positions: • pulled out completely: primary and secondary air inlet are open. • pressed until the rst click: only the secondary air inlet is open. The stove has now the highest output and gives you the best pos-sible air-wash function.• pressed until the second click: everything is closed, and the stove 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.Avoid nger marksDo not touch the glass of the stove with your ngers. Finger marks will burn into the glass and cannot be removed later.

!20 Adding wood Be sure to re-open the ue gas valve before adding wood. This prevents too much ue gasses from entering the room. After closing the door, you can close the ue-gas valve again. Lighting the stove for the rst time Discolouration of walls, ceilings and grates The walls, ceilings and grates may show some discolouration after lighting your stove. This is caused by the dust particles that burn in the convection cover. WANDERS cannot be held responsible for this natural process. 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 rst time, the stove 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 ‘annealing’ 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 rst 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 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. 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 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 Square 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 that 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 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 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:

• 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 rela- tively 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 combus- tion 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.

• Only add extra air to your woodstove when you start lighting the stove. If you add much air all the time, combustion of the wood is too much boosted by the extra air supply and your stove has too little time to radiate heat to the room. The stove may also get overheated and damaged.

• 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.

• Do not 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. 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 200 millimetres over the entire length, and whether the channel is clean, smooth and leak-proof.

!22 Chimney with 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 eect 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 ue 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

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

• Remove the cooled ash from the stove two or three times a week. We recommend that you use an ash bucket.

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

• 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.

• Oil the hinges and the door fastener occasionally. 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 summertime. This allows a stream of air, which keeps moist from entering the stove.

• Thoroughly clean the stove after a heating season. Pay attention to the ue gas tubes inside the stove as indicated below. The ash container at the bottom can be pulled out by removing the wing nuts.

• Place absorbent salt inside the stove if it is stored in a humid space. Yearly maintenance

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

• Have the ue gas outlet and the combustion air supply of the double-walled ue tube system checked for air-tightness every year.

• Have the complete tube system checked every year; this includes the roof or wall ducts and the outlet just outside the wall.

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

• Have the sealing of doors and glass panes checked for wear and tear. 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 ue tube. Your installer must therefore comply with the installation instructions as listed on page 24 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

2. Prevent small children or the inrm 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 re screen.

must have a minimum size of - 50 cm from the stove, and - 30 cm measured from the replace on all sides from the door.

5. Do not place any combustible materials, such as curtains, wooden objects (cupboards, paintings) close to

the replace or the ue tube. A minimum distance of 80 cm measured from the exterior of the stove and the ue tube is required.

6. Never cover the chimneybreast 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 21.

8. Have your stove repaired only by a certied installer and with original parts.

WANDERS disclaims responsibility for any cracks in decorative plasterwork or discolouration of walls, ceilings and/or grates after burning the replace. Discolouration can be caused when dust particles burn in the convection cover. To minimize the chance of cracks in stucco or plasterwork and of discolouration, we refer to the advice given for decorative hearths. Your installer can give you more information.24 Wanders recommends that the mantelpiece for built-in and recessed replaces should be aerated at all times.Any complaints will be dealt with after the sales rm, the installer or the gas company has led a complaint and sent a copy of the purchase receipt with purchase date. Any repairs do not entitle you to extend the guarantee term. All resulting damage and/or consequential losses are excluded. Installation instructions for the Square The Square is tested in accordance with the international EN13229 standardization. This stove can be connected to a ue tube to which several stoves are connected. The ue tube has a diameter of 200 millimetres. The connection to the convection system has a diameter of 100 millimetres. The heating device must be placed and connected 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 Square is connected or installed incompletely or incorrectly.It is not allowed to build the stove in• stairwells, except in buildings with no more than 2 dwellings;• arcades and corridors accessible to the public;• spaces where highly ammable or explosive materials are processed or 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 you want to connect the stove to an existing chimney, you must rst have the chimney professionally cleaned and checked by a qualied chimney sweep company. Any cut-o 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.

• At the time of placing the stove, the chimney ue must be clean, leak-proof and without obstructions, and must have a diameter of at least 200 mm.

• Any bends in the ue tube should 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, it is 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.

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

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

must resist a temperature of 700 °C and have a density of 80 kg/m3. Please see for insulation materials the table on page 28).

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 Square is tested in accordance with the international EN 13229 standardization. The stove can be connected to a ue tube to which several stoves are connected. The wood burner must be placed by a registered installer; otherwise, the obligations under the guarantee will lapse. Supply of combustion air The stove must have a sucient fresh supply of combustion air. To avoid draft, make if necessary an extra air supply opening as close to the stove as possible. An extra air supply opening is denitely required if:

• the room has a heat recovery system,

• the room has a central exhaust system,

• the same space has a cooker hood. The air supply opening must be sealable if it goes through a re-resistant wall. If there are several heating devices in the same room, there must be enough air openings to guarantee proper combustion. Connecting the Square The Square is a replace of heavy weight. Verify whether the wall or the oor onto which the stove is installed is strong enough to hold the weight. Follow the instructions given in the previous chapter on ‘Preparation’ before installing the stove. Protect the oor during mounting the stove, and mind your back.

1. Check the packaging and if there is any visible damage, please report it.

2. Take the stove from the box.

3. Put the stove in its place; ensure that stove is placed exactly in the middle beneath the exhaust pipe. If26

your stove is tted with optional ventilators, do not damage the cable and be sure that it is not jammed or wedged.

4. Connect the mouth of the pipe to the exhaust duct. Page 24 gives the conditions the exhaust channel

must meet. The exhaust channel must be assembled overlappingly.

5. Place the non-return valve in the stove.

6. Your stove is now ready for use.

WANDERS recommends adding extra air inlets for all recessed, inserted and built-in stoves Repairs Removing the glass To remove the glass, unscrew the frame of the door. There are 3 screws in this frame, and all are on the bottom side. !27
