USER MANUAL Boreal WANDERS

Dear Client, Congratulations on your new wood-burning stove, which will be a comfortable source of heat to enjoy for many years on end. When we developed this wood-burning stove we took special notice of ease of use, safety and design while taking our clients’ wishes and requirements into account. The client can opt for a turn able hearth or for an external air supply connection. When designing this fireplace we took particular care regarding the ease of use, the operational safety and the design. The Boreal is developed and produced at our own factory in Netterden (the Netherlands) and is for the greater part handmade. Only the best materials are used for the construction and comply with current international standards. This will guarantee that your woodstove has a long life. The first part of this user’s guide gives you tips and directions about how to use your wood-burning stove correctly and safely. The second part of the manual contains the installation instructions and the technical specifications of the Boreal. They are of particular importance to the installer. We advise you to read this manual thoroughly before using your new stove and to keep the manual in a handy place. Your installer may need the manual for the yearly maintenance of your fireplace. We wish you much warmth with your new fireplace!

Your Boreal wood-burning stove at a single glance The Boreal The Boreal is available in various models and there is even a rotatable version. The rotatable hearth can turn 120º at most while meeting all fire safety standards. The stove can be rotated gradually (15°). The Boreal stove is provided with an energy-saving valve in the pipe socket for having a higher output during operation. The Boreal also has the option for connecting an external air supply (only via the bottom side). The air supply needed for fuel combustion can be adjusted with a rotating air valve. Combustion air is heated by an ingenious air circulation system, which is then combusted via a window cleaning system. This technique gives cleaner combustion and at the same time a higher heat output, which means less fuel consumption. The Boreal is a combination of comfort and efficient heat output. The stove has an outside cover and an interior chamber. This ensures that the stove radiates 60% of the heat output through convection to your room while the remaining 40% heat is released through radiation via the glass area. Please note: The glass side of the hearth must never face the wall or other flammable materials during lighting and for the following two hours after using the hearth. 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 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 stove. Please bear the fire safety in mind when installing the stove. See also page 20. The wood-burning stove is suitable as an extra heat source and does not replace your principal heating device. It is not allowed to have wood-burning stoves connected by unqualified installers. In such case we cannot give any guarantee that the Boreal will work properly. 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. Opening the door 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.18 The airsupply control The shaking bar Energy saving valve Open the large ornamental cover and the door (see photograph) and put some balls of paper or firelighters in the stove with some wood kindling on top. Fully open the air supply valve and the energy-saving valve (see photograph). Open the grate shaker with the shaking bar and keep the ash collector open for the first five to ten minutes for extra air supply (see photograph). Light the kindling and leave the door ajar for extra air supply. Once the kindling is burning you can add extra fuel and close the door, the shaking grate and the ash pan. Do not place more than three logs in the stove at a time. Once the stove is burning nicely, you can first close the energy- saving valve and, if necessary, then turn the air supply valve to slow down the fire. Be sure that there is always enough ventilation when the woodstove is burning. Open the energy-saving valve before putting logs on the fire to avoid smoke entering the room. After replenishing the fuel you can push the valve close again. If you have a revolving version you can turn the stove by turning the pull-out switch. You can turn the stove at most 60º to the left and 60º to the right for reasons of fire safety requirements. Pull-out switch 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 When you light the stove 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 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. 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.19

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.

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. Fuel: wood Wood species 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 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 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:

• Foraregularcombustion,closethegrateshakerwhen the stove is fuelled with wood.

• Ifyouclosetheenergy-savingvalveduringoperation you will save a considerable quantity of fuel and increase heat output at the same time

• 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.

• Donotputmorethan3logsonthereatonetime.Too much fuel at one time thwarts efficient combustion and burdens the environment unnecessarily. 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. 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.20

• Ventilatethespacewellwhenyouhavethestoveon. 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.

• 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’tsmothertheresuddenlywithwater,butletit burn out. The materials inside the stove may deform or crack as a result of sudden or great differences in temperature.

• Ifyouwanttotemperthere,rstclosethevalvein the flue tube and then close the air supply. 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 150 millimetres over the entire length, and whether the channel is clean, smooth and leak-proof. Maintenance Small maintenance

• Remove the cooled ash from the ash pan twice or thrice a week. It is advisable to use an ash bucket. An empty ash pan is important since the stove also draws in combustion air via the ash pan.

• Itis advisableto leavean ashlayerof twoto three centimetres. It will protect the fire plate.

• Clean the shaking grid inside the stove with a soft brush.

• 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.

• Cleanthecoldglasspanewithacleaningagentfor ceramic cooking rings. Do not touch the clean glass with your fingers. Finger marks burn into the glass.

Fire safety starts with proper installation and a flue tube that is in good working order. That is why your installer must adhere to the installation requirements as given in page 22 and further. To burn your stove safely, the following points are important:

1. Burn your stove as much as possible with its door

closed;itwillimprovetheoutputandismuchbet- ter for the environment.

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. 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.21

too close to a burning stove, and never leave them alone in the room when the stove is burning. You could use a fire-screen.

3. Do not pour combustible liquids or put combus-

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

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

combustible materials (such as wallpaper).

5. The Boreal wood-burning stove should never be

6. There must be a distance of at least 10 cm in all

rotated positions measured from the Boreal stove to the fire-proof wall behind it.

7. For safety reasons, there must always be a distance

of over 80 cm measured from the glass area of the hearth to the wall.

8. 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 100 cm is required, measured from the exterior of the stove or from the flue tube.

9. If the floor around the fireplace is made of combus-

tible material you must use a floor slab. Please see the installation requirements on page 23 for mini- mum distances.

10. Have your wood-burning stove only repaired by a

certified installer and use original parts.

The rotatable hearth can turn 120º at most while meeting all fire safety standards. The stove can be rotated gradually (15°). To turn the rotatable model properly, the external air supply and the flue tube must be at right angles. The Boreal stove is provided with an energy-saving valve in the pipe socket for having a higher output during operation. The Boreal also has the option for connecting an external air supply (only via the bottom side). The diameter of the air supply duct is important; the diameter of the air supply duct is 100 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 stove is connected or installed incompletely or incorrectly. It is not allowed to place the stove in:

• Arcadesandcorridorsaccessibletothepublic.

• Stairwells,exceptinbuildingswithnomorethan2 dwellings.

• Spaceswherehighlyammableorexplosivematerials are used.

• Spaceswhereanexhaustsystemisusedorwherea mechanical exhaust system is placed, except when the air supply is taken directly from outside to assure a hazardless combustion. Preparation The chimney flue Before placing the stove you must observe the following points:

• Ifthestoveisconnectedtoanexistingchimney,you must first have the chimney professionally cleaned and checked by a qualified chimney sweep company. Any cut-off valves or stop valves must be removed.

• Theuetubeofthestovemustbeconnectedwiththe chimney without diversions.

• Thechimneymustalwaysreachoutletarea1.Ifitdoes not, it will increase the chance of a reverse chimney flow or inverted draught.

• At the time of placing the stove, the chimney ue Installation instructions Boreal General instructions 22 Preparation 22 Installation 23 Repairs 24 Technical details Boreal 2523

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.

• Ensurethatthechimneytubecandischargetheue gases adequately, properly and safely. 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:

• thesamespacehasacookerhood. 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. With the Boreal you can also opt for an external air supply connection to the bottom of the stove. The length andthediameteroftheairsupplyductareimportant;the maximum length of a 100 mm diameter air supply duct is 1 meter and the duct can have one bend of 90°. If the duct exceeds 1 meter you must increase its diameter. Fire Safety For reasons of fire safety is it important to observe the instructions below before installing the stove.

1. The free distance from the fire-proof rear wall is at

least 10 cm in each rotated position.

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 flue tube.

3. Wooden construction parts within the radiation

range of the stove (80 cm from the exterior of the stove) must be covered with fireproof material.

4. 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.

5. Keep a distance of at least 50 cm (in all directions)

between the stove and supporting steel construc- tion parts.

6. Shield off all combustible materials within a radius

of 80 cm from the stove openings with non-com- bustible materials.

7. 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 on page 26).

8. 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 Boreal is tested in accordance with the international EN 13240 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 Boreal must never be inserted into a wall. 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 Boreal is connected or installed incompletely or incorrectly. Connecting the fireplace Be sure that the floor is strong enough to hold the weight of the hearth without problem. Before mounting the hearth, follow the instructions given in the previous chapter. Protect the floor when you mount the stove, and mind your back.

1. Is the packing undamaged? If you detect any visible

damage, please notify the factory.

2. Is the chimney duct clean and open? (See the chap-

ter on ‘Preparation’.)

3. Is the air supply duct clean and open? (See the

chapter on ‘Preparation’.)

4. Are the fire safety requirements met? (See the chap-

ter on ‘preparation’.)

5. Remove the screws for transportation safety.

6. Put the hearth in its position (Be sure not to damage

the floor and please mind your back while lifting!)

7. Secure the duct between the hearth and the exhaust

pipe. Connect it in the straightest possible way. The flue gas duct must be made of at least 2 mm steel. Please note: the duct may expand by about 1 cm per meter of its length. Ensure that the discharge duct does not get jammed between the mouth of the pipe and the ceiling. If this is the case with the rotating stove, it will be harder to turn the stove.

8. Connect any external combustion air supply. If you

have the Boreal on a support, you must first take away the front cover.

9. Place the baffle plate into the baffle supports.

10. If you opted for the turn able model, you must

check whether the hearth can rotate smoothly. You can check this by pulling the knob underneath the hearth towards you and by turning the stove.24

11. The installation is now completed and you can light

your stove. Please see the chapter on “Lighting the stove”.
