The best way to burn your stove

Your Véro stove at a single glance 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 Véro 33 Serpentino The Véro 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. Installation It is common practice for the dealer where you purchased your Véro 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 Véro stove. Please bear the fire safety in mind when installing the stove. See also page 22. 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 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:

1. Opened all the way: the primary and secondary air

supply is open. 2. Pressed until the first click is heard: only the secondary air supply is open and the stove will produce the highest yield while the glass cleaning system works optimally.

3. Pressed until the second click is heard: everything is

closed, and the fire will go out slowly. The wood-burning stove is suitable as an extra heat source and does not replace your principal heating device.

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. 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 Véro 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. Fuel: wood Wood species Fir, Poplar Lime, Willow, Spruce, Birch, Ash, Alder Fruit trees, Beech Oak Drying time year years years years The Véro only burns on wood. Do not put more than 1 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. 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. 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. Newly-built house or recently renovated? Wood species and storage 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. 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 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.
• 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 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. Maintenance Small maintenance
• It is advisable to leave an ash layer of two to three centimetres. It will protect the fire plate.
• 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 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. 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

frame to let the wood dry from underneath and to prevent the lower logs from being in contact with water. 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

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 19.

General instructions The Véro 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 flue tube has a diameter of 150 millimetres. are 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. 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 Véro is connected or installed incompletely or incorrectly. 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) 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 Roof slope x larger than 23° Roof slope x smaller than 23°

Preparation 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 150 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 22. 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 26).

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 Véro 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 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:

• the space has a heat recovery system.
• the space has a central exhaust system.
• there is a cooker hood in the same space. 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. Connecting the stove The Véro is a heavy stove. The standing version weighs 160 kg, including the 2-metre flue gas tube. Check whether the floor on which the stove is placed, or the wall to which the stove is fixed, can carry this weight without problem. You must follow the directions given in de previous chapter on ‘Preparation” before installing the stove. Please mind your back and the floor during installation! Mounting the standing model:

1. Check the packing. If you detect any visible damage, please notify the supplier.

2. You will have 2 different boxes for the standing

model (1 box for the stove, and 1 box for the base).

3. Take the stove from the box.

4. Turn the stove carefully on its backside (put something underneath to protect the floor)

Take the base from the box. Refasten the base with the 4 screws. Put the stove in an upright position. (Mind your back!) Put the stove in the right place and make sure that it is positioned right beneath the chimney. Now connect the flue tube. The flue tube must be connected overlappingly, with the upper sections fitting into the lower sections. Built-in version: To install the insert model one needs to remove the 4 attached strips on each corner. WANDERS recommends to add extra air inlets with all built in stoves Fasten the base
