Installation Instructions for the Kanda

Your Kanda stove at a single glance source and does not replace your principal heating device. Usage 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. Lighting the stove The Kanda The Kanda 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. The Kanda is equipped with 2 connections for the convection system. The supply of combustion air can be adjusted by handling the air grates. Open the door and put some balls of paper or firelighters in the stove and place some wood kindling or brown coal briquettes on top. Light the kindling or briquettes and leave the door ajar for extra air supply. You can close the door after a couple of minutes. Do not place more than three logs in the stove at a time. Be sure that there is always enough ventilation when the stove is burning. The ash pan must be cleaned regularly to prevent damage. Installation It is common practice for the dealer where you purchased your Kanda 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 Kanda stove. Please bear the fire safety in mind when installing the stove. See also page 22. Open the door The wood-burning stove is suitable as an extra heat

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. 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. The inside of the stove is made of chamotte. It is important that you light the stove for a longer period (5-6 hours) of time during the first 4 times. This is to vaporize the moisture in the chamotte. During these first times the window will turn black. Please clean the windows before lighting the stove again. Newly-built house or recently renovated? Airsupply controls 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. 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 Kanda 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

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 Kanda only burns on wood. Do not put more than 1 to 2 kg of fuel in the stove at the time. Always use clean What to do in case of chimney fire. In case of chimney fire, immediately close the shutoff 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. 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 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. 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. 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:

• 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.
• Let extra air into your wood stove only when you start firing the hearth. A constant oversupply of air will make the logs burn more rapidly while your hearth will not have enough time to give off its heat to the room; if you overheat the stove, it may get damaged.
• 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.
• 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 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 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. 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. 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-down ash from the ash bucked two or three times a week.
• 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 once in a while. Do not use any aggressive cleaning agents or abrasives

will considerably dampen the pleasure of burning your stove and the heat output. to maintain your stove. When the stove is not used

• Close all doors and air inlets in summer season
• 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 airtightness 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 checked for their functioning.
• Have the sealing of doors and glass panes checked for wear and tear. combustible material (e.g. paper covering).

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 23 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 beyond repair.

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

The guarantee does not include: the glass, failure due to improper use; non-compliance with the national regulations and enclosed installation and operating instructions; installation by an installer of dealer who is not acknowledged by WANDERS, negligence of the unit and change of owner. The guarantee is also disclaimed when a wrong fuel is used. There is a one-year guarantee period for the following parts: all cast-iron and vermiculite parts, the control parts of the convection system and the lacquer. WANDERS disclaims responsibility for any cracks in stuccoed walls or discolouration of walls, ceilings and/ or grates after burning the fireplace. Discolouration can be caused when dust particles burn in the convection cover. To minimize the chance of cracks in stucco and discolouration we refer to the advice given for decorative hearths. Your installer can give you more information. Any complaints will be dealt with after the sales firm, the installer has filed 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 consequential damages or loss are excluded. Installation Instructions for the Kanda General instructions

General instructions 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 Kanda 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 flammable or explosive materials are used. Roof slope x larger than 23°

• 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 flue Before placing the stove you must observe the following points:
• If the stove is connected to an existing chimney, 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.
• 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 (see the drawing and the table below) Roof slope x smaller than 23°

The Kanda is tested in accordance with international EN13229 standardization. This hearth can be connected to a chimney to which several stoves are connected. The duct for the chimney has a diameter of 200 mm. The connection to the convection system has a diameter of 150 mm. Height of chimney on the roof at a horizontal distance A measured from the ridge Roof with slope X On the ridge 25o 30 o 35 o 40 o 45 o

Horizontal distance A from the ridge, in metres

• At the time of placing the stove, the chimney flue must be clean, leak-proof and without obstructions, and must have a diameter of 200 mm.
• Any bends in the flue tube must not exceed 45 degrees.
• Ensure that the chimney tube can discharge the flue gases adequately, properly and safely.
• The values for calculating the chimney tube is given in the section on Technical Information, page 24. Fire Safety For reasons of fire safety is it important to observe the instructions below before installing the stove.

1. 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.

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 construction parts.

6. Shield off all combustible materials within a radius of

80 cm from the stove openings with non-combustible materials.

7. Never cover the chimney breast with combustible

material (e.g. paper covering).

8. 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 30).

9. 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 Kanda 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. 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 Kanda

1. First follow the instructions given in the previous

chapter “preparations”.

2. Remove any block-off plate from the existing fireplace.

3. Insulate the stove between the wall and the outside

cover with non-combustible materials. (Please see the table on page 30 for insulation materials).

4. Ensure an air-tight connection to the outside. You

may also position a 200 mm diameter duct to line an existing chimney. Mount this duct to the stove.

5. Remove the flue collar from the stove. (See illustration 1)

6. Place the hearth on a level concrete floor as the

hearth is very heavy. Removing the flue collar from the Illustration 4

Then build the mantelshelf around it; please remember to use only non-combustible materials. Place the convection grates on the right and left sides of the fireplace. Connect the flexible convection tubes to the mouths of the convection tubes. Mount the tube mouths on the hearth. You must install them to ensure proper heat output of the stove and to prevent the walls from cracking. Connect the lower two tubes to the ventilation ducts. If the room is mechanically ventilated or equiped with a heat recovery system connect the duct to the outside air by using additional tubes. In the last situation also connect the upper two tubes to the outside air. (see illustration 6). Mount the energy-saving baffle and place the push rod into the recess in the front of the stove’s door. Hang the valve on the hooks of the hinges (see illustration 2). Place the flue gas regulator on the supports underneath the energy-saving valve (see illustration 3) If necessary, replace the model tag with the model tag in your language. (illustration 4)) Then close the front side of the chimney cover with a 20 mm promatec H plate and ensure that the plate does not make any contact with the hearth on the inside. Please remember to put the stucco frames around the opening of the hearth to prevent cracking. Never attach the stuccowork to the hearth but always leave 3 mm open around the built-in frame and the stucco frames.
