Your Square wood-burning stove at a single glance
The Square 75 Tunnel Jules
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 integrated flue gas deflector ensures that extra heat is taken from the flue 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 flues 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 certified installer. A certified installer can also give you the right advice about the flue tube 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 fire 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 differ 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 off. Do not touch the stove without protection during firing and for two hours after. Handle the stove always with a glove to avoid getting serious burns.
Before lighting the stove, wipe off any deposit on the glass with a tissue or soft paper; you can use this paper for lighting the fire.
Slide the valve in the flue gas pipe open. Slide the air slide valve to the maximum position before lighting the fire. Shove the 'ECO' slide all to the left. Open the door, put some balls of paper or some firelighters 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 fire to encourage the flames 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 flue gases are now led via the flue 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 first click: only the secondary air inlet is open. The stove has now the highest output and gives you the best possible 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 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.
Adding wood
Be sure to re-open the flue gas valve before adding wood. This prevents too much flue gasses from entering the room. After closing the door, you can close the flue-gas valve again.
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 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 first 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 first 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 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 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 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 4kg of fuel in the stove at the time. Always use clean and cut logs that 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 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 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.
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.
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 relatively cold air will cool the fire. It will also preclude fire damage by any sputtering sparks, especially from softwood.
- Do not put more than 3 logs on the fire at one time. Too much fuel at one time thwarts efficient combustion and burdens the environment unnecessarily.
- Ventilate the space well when you have the stove on. 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.
- 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 fire suddenly with water, but let it burn out. The materials inside the stove may deform or crack as a result of sudden or great differences in temperature.
Chimney and flue
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 qualified chimney sweep must check whether the chimney flue has a diameter of at least 200 millimetres over the entire length, and whether the channel is clean, smooth and leak-proof.
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 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.
What to do in case of chimney fire
In case of chimney fire, immediately close the shut-off valve in the flue 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.
Maintenance
Small maintenance
It is advisable to leave an ash layer of two to three centimetres. It will protect the fire 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 off fluff. 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 fingers. 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 flue 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 qualified chimney sweep every year; this is for safety reasons and any fire insurance.
- Have the flue gas outlet and the combustion air supply of the double-walled flue 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 flaps 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 flue 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:
- Burn your stove as much as possible with a closed door; it increases the output and is better for the environment.
- 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.
- Do not pour or put combustible liquids and materials in the stove; this may damage the fireplace beyond repair.
- 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 -50cm from the stove, and -30cm measured from the fireplace on all sides from the door.
- 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.
- Never cover the chimneybreast or mantelpiece with combustible material (e.g. paper covering).
- Please bear in mind the points of the section on 'the best way to burn your stove', on page 21.
- Have your stove repaired only by a certified installer and with original parts.

Installation instructions for the Square
The Square is tested in accordance with the international EN13229 standardization. This stove can be connected to a flue tube to which several stoves are connected. The flue 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 flammable 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 hazardous combustion.
Preparation
The chimney flue
Before placing the stove, you must observe the following points:
If you want to connect the stove to an existing chimney, you must first have the chimney professionally cleaned and checked by a qualified chimney sweep company. Any cut-off or stop valves must be removed.
The flue 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 flue must always end up in outlet area 1.
X>23°
X<23°
- At the time of placing the stove, the chimney flue must be clean, leak-proof and without obstructions, and must have a diameter of at least 200mm .
- Any bends in the flue tube should not exceed 45 degrees.
- Ensure that the chimney tube can discharge the flue gases adequately, properly and safely.
Fire Safety
For reasons of fire safety, it is important to observe the instructions below before installing the stove.
- 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 chimneybreast with combustible material (e.g. paper covering).
- The wall behind the stove must consist of, or be insulated with, fireproof materials. The insulation material must resist a temperature of 700^ and have a density of 80kg / m3 . Please see for insulation materials the table on page 28).
- 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. The stove can be connected to a flue 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 sufficient 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 definitely 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 fire-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 fireplace of heavy weight. Verify whether the wall or the floor 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 floor during mounting the stove, and mind your back.
- Check the packaging and if there is any visible damage, please report it.
- Take the stove from the box.
- Put the stove in its place; ensure that stove is placed exactly in the middle beneath the exhaust pipe. If
your stove is fitted with optional ventilators, do not damage the cable and be sure that it is not jammed or wedged.
- 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.
- Place the non-return valve in the stove.
- Your stove is now ready for use.
WANDERS recommends adding extra air inlets for all recessed, inserted and built-in stoves
