1. INTRODUCTION

1.1. PREFACE

We would like to congratulate you on your purchase of this modern BARBAS stove. This quality product will give you years of heating pleasure as you enjoy the play of the ames and the cosy glow of the re. This manual contains directions for both positioning the appliance and for its environmentally-friendly use. It also contains technical data for the appliance, parts information and directions in the event of problems. Study this manual carefully before using the stove. We recommend you keep this manual in a safe place for reference purposes.

1.2. SAFETY AND INSTALLATION INSTRUCTIONS

Safety

• Do not place ammable objects within 80 cm of the appliance. Pay special attention to furnishings and ornaments around the stove.

• To ensure safe operation, the following minimum distances must be maintained between the appliance and any existing side or rear wall (temperature ≤ 80 °C).

ECO 60/90/100 : in respect of side wall : Distance ≥ 10 cm ECO 60/90/100 : in respect of rear wall : Distance ≥ 10 cm

ECO 70 : in respect of side wall : Distance ≥ 80 cm ECO 70 : in respect of rear wall : Distance ≥ 10 cm

• If the oor is ammable, a nonammable oor plate should be used under the appliance. Use the oor plate as mentioned in chapter 2.2.

• When you use your stove, the exterior will become hot. Always wear the glove or use the accessories supplied when lling etc. Protect yourself and others (especially children!) from burns. Do not leave children unattended when the stove is burning.

• Watch your clothing. Synthetic clothing in particular can easily catch re and burn intensely.

ECO 60 / 70 / 90 / 100

• Do not approach the appliance with ammable materials or liquids. Any work with solvents, adhesives etc. in the space heated by the stove can be very dangerous.

• Make sure you know what state your chimney is in. Cracks in the chimney may not only lead to damp, staining of walls and leaking of smoke, they can also impair the carrying off of smoke. Make sure you get proper advice from your Barbas dealer or other specialist company.

• Avoid chimney res! Have your chimney swept at least once per year - more often if you use your

stove a lot.

Prevent excessive deposits of soot inside the chimney by not burning freshly-cut wood. Instead, burn clean, dry chopped wood.

• Do not use your stove as a barbecue. This can cause (ammable) fat deposits to be left in the chimney and hastens the chimney becoming clogged. Prevent your chimney being soiled from above (birds’ nests etc.) by tting a suitable cap to the chimney pot.

• Follow the instructions issued by your local re brigade.

The stove can be taken in operation if national and local regulations are

satised. The required constructive adaptations should be satised as well.

Installation Instructions

• Wood and wood bricks can be burned in the stove.

Coals can’t be burned in the stove.

• Never use the stove to burn rubbish.

• Read all instructions/stickers, on and around, the appliance.

• Carefully read the user manual before using your appliance for the rst time. When you rst re up your appliance, there are a number of extra points you should take into account. See section 5.

• Never use liquid fuels, such as petrol, lighter uid etc.

Use of these could cause dangerous situations and damage your appliance.

ECO 60 / 70 / 90 / 100

• In transit, some parts of the appliance may have moved from their original place. Check that the door opens and closes, the brake plate is tted correctly to the brackets at the top of the re, the side panels are xed to the walls and the panels on the bottom have not moved. Check whether the grate is lying correctly and there are no foreign objects in the ashtray.

• Avoid over-loading (white burning glow), caused, for example, by lengthy burning with primary air (combustion air supply slider all the way to “ + ”) or by burning too much wood in one go. The stove can then become overheated.

This may damage the grate and the metal ue gas ap (ECO 60).

• Consult the current local building regulations before starting the assembly.

• Check the operation of the slider for controlling the combustion air.

ECO 60 / 70 / 90 / 100

• Report any defects immediately to your dealer.

• Remove enclosed documents and components from the stove.

Have the suitability of the area in which the stove is to be placed (and the chimney) approved by a specialist. The stove must have its own chimney, constructed in compliance with current legislation.

ECO 60 / 70 / 90 / 100

3. INSTALLATION INSTRUCTIONS

3.1. FITTING INSTRUCTIONS

When tting the stove, local and/or national regulations relating to re safety must be followed. In case of doubt, consult the re safety department of the local re brigade, particularly if the stove is to be tted in a home with walls and/or oors containing ammable material.

Position the appliance sufciently far away from the wall behind it, according to the data from chapter 1.2. If the walls are not re-proof, the distance should be such that the wall in question cannot become hotter than 80°C, even when the stove is stoked up to high temperatures. In case of doubt, insert a re-proof protection shield. The oor on which the appliance is placed must have sufcient bearing power.

The connection of several appliances to a single ue/chimney is not allowed.

3.2. CHIMNEY

Be sure that existing chimneys are completely air-tight and in good condition. In terms of dimensions, the chimney must have a diameter of at least 150 mm for the entire length (including the chimney pot). Ensure that the chimney is tted with an appropriate cap to avoid rain and dirt getting in (as well as bird’s nests). The draught owing through the chimney determines how well your stove will burn (recommended draught 0.15 mbar: = 15 Pa). In the event of problems, a solution may be a different chimney cap, if necessary one with a chimney fan. Contact a specialist if you have any doubts about any of the above points.

If your chimney is unsuitable, or if your home does not have a chimney, we recommend the use of double-walled stainless steel chimney sections. Chimneys must comply with the prevailing building regulations. Make sure the building is carried out by a specialist. When purchasing such chimneys, be sure to check if a casing is required.

ECO 60 / 70 / 90 / 100

Important:

• Chimneys must be free-standing, i.e. they must not rest on the appliance itself.

• Any pipe connections that are not insulated must also be fully insulated.

• Flammable material must be kept clear (outside the casing/insulation zone) of all through-feeds in the oor or wall (remember the roof decking).

• The chimney opening must be at least 5 metres above the top of the door opening of your appliance.

• The chimney must protrude at least 40 cm above the apex of a sloping roof and at least 1 metre above a at roof. In short, the chimney must always end in an area with a negative air pressure. Contact your local chimney sweep for the exact dimensions of the chimney opening.

Between the stove and chimney, use thick-walled smoke piping (Steel, ≥2 mm).

See Chapter 2.2.

The rst pipe connected to the appliance must have a diameter of 150 mm (int.) at both ends. This will prevent any condensation from the chimney running over the external end of the pipe. Connect the pipes to the existing chimney (ceiling) using a sliding sleeve (niche pipe). Check all connections for air-tightness.

If there is too much draught running through your chimney (e.g. if the chimney is long and straight in a tall building), it may be possible to insert a chimney valve in the pipe near the appliance. Before doing this, be sure to obtain sound advice from a specialist.

Do not make any horizontal connections. Deposits and soot will accumulate here (unless it is a short horizontal connection directly behind the stove). Avoid bends at all costs. The maximum deviation from the perpendicular is 45°.

The chimney calculation, as in Germany, is made according to DIN 4705 parts 1 and 2.

ECO 60 / 70 / 90 / 100

The mass ow and exhaust temperature of the stove The mass ow and exhaust temperature of the stove are shown in chapter 13; Technical Data. These values are important to consider when assessing the dimensions of the ue to which the stove is to be connected.

Cleaning the chimney/ue Make sure your chimney/ue is cleaned at least once a year by a recognized chimney sweep.

If the chimney has a chimney valve, the free opening in the chimney valve ap must measure at least 12% of the surface.

3.3. AERATION / VENTILATION

A stove generates: - heating air

- combustion air

Heating air (convection air) is devoted to the convection of heat from the appliance to the room. The source of heat is in the room and stays there.

Combustion air is needed to keep the combustion going by drawing in air from the room, or directly from outside, due to the natural draught of the chimney.

• Combustion air from the living-room: The air inlet opening; Ø125 mm, is found at the rear of the appliance. When

using the appliance, please ensure there is a sufcient supply of fresh air:

minimum 150 cm2 (Ø125 mm) opening in the room where the re is placed.

Make sure that the ventilation supply is open; this is particularly important

with today’s airtight dwellings.

If the dwelling has mechanical ventilation that creates under pressure in the room where the appliance is located, it is necessary to t a ue gas fan. The type of ue gas fan is dependent on the capacity of the mechanical ventilation system. Always consult your tter about this.

In dwellings with an operating extractor hood, this should be turned to the lowest setting or turned off altogether. If the extractor hood remains in use, additional ventilation must be provided in

compensation.

ECO 60 / 70 / 90 / 100

This will not only avoid poor combustion, but will also prevent ue gases being sucked from the appliance into the room. Should creating an extra ventilation opening prove insufcient, it is then necessary to t a ue gas fan.

• Combustion air directly from outside:

The appliance now has a completely closed combustion system, which allows it to operate independently of the surrounding air in the room where the appliance is located.

3.4. FITTING THE STOVE

If you have had your chimney breast modied or newly built, rst allow your home to dry properly. Walls which have not been allowed to dry properly are a magnet for dust such as any smoke particles created when stoking up the re or suddenly opening the door. Even scorched dust can easily be retained by damp walls. Think also of dust on the outside of the appliance or on hot radiators etc.

Check that all packaging, stickers etc. and/or all dust and waste has been cleaned up after the installation work (to avoid it getting scorched/causing a bad smell).

Check again that all moving parts are in order and that loose parts such as the retardant plate (brake plate), ue gas ap, interior panels, grate etc. are in the correct position. They may have moved during installation.

The stove has a heat-proof nish. It only hardens at high temperatures. When unpacked, it is therefore not fully hardened. It can easily be damaged at this

time.

Begin stoking up the re with a low ame (see section 6). Increase the heat gradually for approx. 2 Hours until you reach the correct output. Keep it at this level for another 2 - 3 hours. The nish will now be properly hardened and can be touched without damaging. The hardening process creates a nasty, though harmless, smell/vapour.

Check at the start of the heating season that the ue/chimney is not blocked, for example by a bird’s nest.

Adequate ventilation is of the utmost importance.

ECO 60 / 70 / 90 / 100

6. USE

6.1. VENTILATION

Air is a vital component of the combustion process. Ensure that there is a sufcient supply of fresh air. For each kilo of wood that you put on the re (door closed), 10 - 15 m3 of extra air is needed. That means 50 m

per hour! As you can see, a plentiful supply of air is essential. Fresh air supply opening: minimal Ø125 mm.

6.2. GETTING THE FIRE GOING

When you start the re, the chimney is still cold and there is little draught. This means that the chimney’s capacity to draw in air is limited. That is why the air supply has to be assisted by opening the locking (ECO 60) (and/or the door) and air supply slider. Use dry, ne wood and some scrunched-up paper or relighters to start the re.

Locking for operating pin of ue gas ap (inside of door). (ECO 60)

ECO 60:

Locking closed (turned to the left) Locking open (turned to the right)

close open

Locking all the way to the left (closed): Flue gas ap operation works normally:

Door open Pin comes forwards Flue gas ap open Door closed Pin is pressed in by the door Flue gas ap closed

Locking all the way to the right (open): Flue gas ap always remains fully open !!

ECO 60 / 70 / 90 / 100

When setting the re, turn the locking all the way to the right (ECO 60). If necessary, leave the door ajar for 10 minutes. Do not open the door wide, as the window will remain cold. If the door is shut during this time, smoke will condense on the glass and form soot. Move the air supply slider all the way to the right “ + ” only when starting the re.

Prevent white glow and over-ring.

6.3. INSTRUCTIONS WHILE STOKING

After approx. 10 minutes, the re will be burning ercely. You can now top it up with a few larger blocks of wood. Turn the locking all the way to the left (ECO 60) when these blocks are burning well, and close the door.

Using the air supply slider you can now adjust the air supply for further

combustion. Make sure the re burns quietly.

Note: Once you have got the re going, leave the air supply slider in the centre position for optimal combustion. Your re will then be much cleaner and more efcient (more heat, less topping up).

ECO 60 / ECO 70

ECO 60 / 70 / 90 / 100

We recommend that you maintain a substantial layer of ash (2 - 3 cm). This not only forms a protective layer for the base of the appliance but also signicantly reduces consumption of fuel and allows new wood to catch light easier.

When loading the stove with fuel, two blocks measuring 15 cm long and 40 cm perimeter (ECO 60), (18 cm long and 40 cm perimeter (ECO 70)), (17 cm long and 40 cm perimeter (ECO 90/100)) is sufcient. Do not add more fuel until the previous fuel has burned down to the charcoal stage. This is after approximately 45 minutes. The ames are then almost no longer visible. Do not leave the door open longer than necessary.

Weather conditions

In order to reduce pollution and any other inconvenience, we advise not ring up the stove when there is no wind, or in foggy/misty conditions.

Smoke development

Your stove has been designed to be used with the load/observation door closed. Should you use it with the door open, under certain circumstances (presence of mechanical ventilation, draught, differences in barometric pressure) smoke may enter the room in which the stove is situated.

ECO 60 / 70 / 90 / 100

Use of the stove

Your stove is suitable for periodic use. The appliance is tted with a soapstone (ECO 100) or steel (ECO 60, ECO 70, ECO 90) casing on the outside. ECO 100: Soapstone casing: This casing rst absorb a lot of heat (heat accumulation) before emitting (radiation / convection) warmth. Using the stove for short spells is inefcient.

The stove may only be positioned in a place where the location, construction and activity in the room can accommodate it without danger.

Ventilation

When using the stove, ensure a good supply of fresh air. The combustion air can namely be drawn from the room where the stove is located. Turn on the ue gas fan if the ue is tted with one.

Spare parts

Any replacement parts must be new, original parts. Use of non-original/ reconditioned parts will invalidate your warranty.

Modication

Do not make modications to your stove. Any alteration to your stove, of whatever nature, will also invalidate your warranty.

Only open the door for lling and lighting the stove and for removing the ash. Keep the door shut at all other times.

Continuous stoking with the primary air supply open (combustion air

supply slider is right over to the “ + ” position) (air through the grate)

causes a ercely white-hot re that can damage the grate and other

parts of the stove.

ECO 60 / 70 / 90 / 100

6.4. HEATING ECONOMICALLY

The most environmentally-friendly and economic way of heating with wood is to have your re hot but calm. The ash should appear to glow a soft red-orange and should not glow like a blacksmith’s re. Fires like that burn quickly and intensely, leaving little time for complete combustion.

Your re is at its most economical when:

• Burning with the door closed. This makes the re hotter and improves

combustion.

• Using dry and clean wood (as described further in chapter 8).

• Always ensure even combustion. Stoke with the primary air regulator closed. To do this, place the air supply slider in the centre position.

• The bed of the re should be composed of one material and the re must

have easy access to air. Position the blocks of wood (loosely and evenly) horizontally on the bed of ash, so that they are separate and several centimetres away from the walls.

6.5. CLEANING THE WINDOW

After several burning hours, a light deposit may form on the inner side of the window. Once the stove has cooled down, this deposit can be removed using glass cleaner or ceramic hob cleaner.

ECO 60 / 70 / 90 / 100

7. GENERAL HINTS

7.1. TIPS

• Burn dry wood only. Damp wood not only burns poorly, it causes more pollution in the appliance (window), the chimney, your room (when opening the door of the appliance, for instance) and the environment. Wood can only be classied as dry if it has been stored under a Dutch barn for at least two years (not covered with plastic). Never use painted or impregnated wood. The gases emitted when burning painted or impregnated wood are aggressive and will affect the appliance, the environment and your health.

• Ensure that your re burns well. The smoke generated should be translucent or white and the windows of the re will remain clean. We recommend that you do not ‘pinch off’ your stove (by closing all air openings). Doing so will hinder combustion which, apart from polluting the atmosphere, will lead to deposits of soot and tar in your chimney (which, unchecked, will increase the risk of chimney re).

• Keep the door shut when the re is burning. Doing so improves the performance of your re 8 - 10 times, beneting the environment and the heat in your home (less topping up, see section 7.2). You will also prevent re damage from any particles the re ‘spits’ out (this is a particular problem with softwood from conifers). If your oor contains ammable material, an extra oor plate is required.

• Avoid lighting a re in misty or still conditions. If the wind is still, there is hardly any draught in the cold chimney. As smoke is heavier than air, there is a chance that smoke will enter the room. If there is mist in the air, smoke coming out of your chimney will cool quickly and fall, causing problems in your area.

• Do not extinguish your re with water - let it burn out.

The part of the inner lining that is in direct contact with the re is clad with

sections of metal and re-resistant material. Sudden changes in temperature may lead to it deforming or cracks appearing.

ECO 60 / 70 / 90 / 100

• Chimney re. If, despite all the precautions, a re should occur in the chimney (you

generally notice that because of a roaring sound in the chimney), do the following:

• Immediately shut the chimney ap (if tted).

• Immediately shut the air supply to the stove.

• Call the re brigade (( 112).

• Quickly quench the re in the appliance with sand or soda in order to prevent smoke in your house.

• Never use water to put out the re.

• Ventilate.

• If there has been a re in the chimney, have it swept and inspected for damage and leakage.

7.2. OUTPUT

In practice, combustion is all about loss. This entails:

• Loss through excess heat leaving the chimney, rather than going into the

room.

• Loss through insufcient combustion, such as CO (carbon monoxide) and

soot particles.

• Loss through excessive unburnt fuel in the ash.

The rate at which fuel can burn completely is called the output. A well-stoked re achieves output of 75% and thus falls into the category of high-output/ low emissions res. This means that you benet directly by using less wood to achieve the same level of heat. The environment benets as well: a well-stoked, high-output appliance means less pollution and fewer odours.

ECO 60 / 70 / 90 / 100

Adverse effects on the output are:

• Burning the re with the door open.

A warm chimney works in the same way as an extractor. When the door is

open, the chimney draws in much more air than is necessary for combustion. This relatively cool air cools down the re.

• Excessive chimney draught.

The combustion air does not reach the fuel, but leaves the appliance via the

chimney. The re cools and the combustion quality decreases.

• Using too much wood.

This is a problem if your stove is too small. In that case, it becomes

overloaded and burns more wood than heat emitted. In this case too the fuel cannot burn completely. More to the point, there is not enough air to mix with the ames. This has an extra impact on the environment.

• Admitting too much air under the fuel.

(Combustion air supply slider is fully over to the “ + ” position.) Combustion is raised to high intensity (like a blacksmith’s re). Combustion

really needs time. If combustion is too intense, there is insufcient time for the stove to radiate all the heat.

The chimney will become excessively hot and the same will be true of the

escaping smoke. This heat is thus lost.

ECO 60 / 70 / 90 / 100

8. FUELS

8.1. WOOD

Suitable fuels are:

• All sorts of clean wood (forested). The wood must have been dried for at least two years. Well-dried wood has a humidity percentage between 10 and 20%.

Recommended dimensions: • ECO 60: length: ca. 15 cm outline: ca. 40 cm

• ECO 70: length: ca. 18 cm

outline: ca. 40 cm

• ECO 90/100: length: ca. 17 cm

outline: ca. 40 cm

• Compressed wood blocks without binder (see wood dimensions).

• Hard woods burn slowly and easily form charcoal; for example hornbeam, oak, ash, beech, elm and birch.

Softwood burns with more ame, but forms less charcoal and radiates less

heat. Examples are spruce, pine, poplar and linden.

Unsuitable fuels are:

• Painted, bonded (chipboard, MDF etc.) or impregnated wood, plastic and other ammable waste. Stoking a re with this is completely forbidden. The combustion gases released by these materials are aggressive and will attack your re and the environment.

• Parafn-containing open re lighters are not suitable for a closed re. A closed re generates more heat than an open re, thus the parafn will melt out of the blocks prematurely.

• Damp wood burns poorly, is unsuitable and produces too much smoke (including in the room when you are topping up the wood), dirties the glass, leaves deposits in the chimney and delivers about half the heat output of dried wood.

The appliance is not suitable for coal ring.

9. AMOUNT OF FUEL

9.1. AMOUNT OF FUEL

The stove is constructed for a certain maximum amount of fuel. Remember that the more fuel you put into your stove, the hotter it will become and overheating may even occur. If this happens, there is a risk of re. It may also damage your appliance and chimney. BARBAS will not assume liability for damage caused by

overheating.

Burning one layer of wood can lead to varying outputs. When used correctly, one load will burn in around 45 minutes. Putting in too much wood at once can lead to the appliance being overloaded.

10. REGULAR MAINTENANCE

• Emptying the ashtray : * Regularly check how much ash is in the

ashtray.

* Make sure the ashtray is never more

than ¾ full. If the ashtray is more than ¾ full, it can obstruct the ow of air to the re.

* Wait 24 hours after stoking before

emptying the ashtray.

• Cleaning the glass : As required

• Door and ashtray seals : Check annually before heating is

resumed. Replace as necessary

• Sweep and inspect chimney : Annually before heating is resumed

• Fire hearth interior : Check annually

* Replace panels as necessary

• Grate : Check annually for cracks / breakage

• Sliders / aps : Check function annually

• Convection channels : Clean annually

• Paint : Annually, if necessary touch up with

BARBAS heat-resistant paint (do not use with open res !)

• Parts : Individual parts for replacement/

accessories are available from your BARBAS dealer

Use only original parts

• Modications : Introduced modications to the

appliance are not permitted

14. FREQUENTLY ASKED QUESTIONS

How often should I have my chimney swept?

At least once a year. If you use your stove more than three times a week on average, have your chimney swept more often. Have the chimney swept by a recognised company. Your re insurance policy may make this a condition and ask for proof.

What is the difference between net capacity, gross capacity and efciency?

Net capacity (= Nominal output) represents the net amount of heat that the

appliance generates.

The total heat content of the fuel is the so called gross capacity.

Efciency is the percentage of fuel converted into useful heat. It is the ratio of net capacity and gross capacity.

How can I keep the glass clean?

By making a point of using dry, clean wood in the stove. Wood that is too damp immediately gives off lots of ash.

Make sure the seals are in good working order. Any air seeping out around the glass part of the door will cool the air, resulting in the re not burning cleanly.

Can a wood-burning stove/replace insert be connected to a central

heating installation?

The Barbas range does not have any stoves/res that can be connected to central heating installations. We do not advise attempting it!!

How do I know if I’m heating correctly?

Follow the instructions in this manual.

The ames should play softly across the wood and the wood should burn evenly.

Once the re has been burning for a short time, the smoke from the chimney should be almost translucent.

What is wrong with a smoking chimney?

A seriously smoking chimney means that combustion is less than optimum. There may be a number of reasons for this. If the re has only just caught on, or has recently been topped up, some smoke is normal. By opening the door for a short period, the wood will catch re quicker and the smoky period will be

shorter.

If you leave the stove door open, and especially if you burn damp wood, the result will be a lot of smoke. In both cases, the combustion temperature is too low. This leaves numerous dangerous compounds intact, which means more deposits in your chimney and more waste into the environment.

What is the inuence of soapstone outer nish on the stove?

Soapstone functions as a heat buffer. Its combination of chalky composition and sedimentary structure means that soapstone heats up more quickly than other sorts of stone and emits heat more gradually than other stone. Soapstone equalise the irregularity that is a characteristic of burning wood (heat radiated is initially double; later half the average). However, this means that a soapstone stove has a longer warm-up period. However, it will continue to give off heat for longer.

The soapstones are not like the ones in the brochure. Is this right?

Soapstone is a type of stone that is found in mountain walls (it is sawn out). Depending on the place in the mountain, the structure may vary. It may be more or less porous, its structure may be wild or calm. This means that the colour and nish may also vary. Stone quarried in the past will thus look different to stone quarried today.

What should I do if the wood does not catch re?

This probably means that the wood is damp. Remove the wood and replace it with dry wood. If necessary, make a re with wood briquettes. They are always dry (they have a moisture content of <10%).

ECO 60 / 70 / 90 / 100

The wood burns up too quickly. What should I do?

Ensure that air cannot get in underneath the fuel. Move the combustion air supply slider towards the “ - ” position. (The primary air supply is now closed.) Under these conditions, the layer of ash should no longer burn bright orange/ white but red.

If there is a draught (due to strong wind), air intended as secondary air for above the fuel may enter through the openings above the door and ow straight down beneath the wood. Also slide the combustion air supply slider tighter shut.

There may be too much of a draught in your chimney, particularly if it is very high (in excess of 8 m). Ask your supplier to t a check valve or damper. This may not be possible in all cases.

Can I leave my stove unattended?

Only do this when the appliance is burning quietly, with just a little wood, with a closed door and with the combustion air supply slider in the centre position between “ + ” and “ - ”. In this position, the primary air supply beneath the grate is closed and the secondary/tertiary air supply is open. Secondary air is supplied through the small holes in the rear panel of the combustion chamber. Tertiary air is supplied through the opening behind the glass at the top of the combustion chamber.

Do not leave children unattended while the stove is burning.

Do I have to take any extra measures if the room I am heating has an extractor fan (mechanical ventilation)?

If the combustion air comes from the living-room: A ue gas fan is required when there is permanent extraction of the area in

which the re is placed. The type of ue gas fan depends on the capacity of the extractor system. Always consult your installation engineer about this.

If the combustion air comes directly from outside via a direct connection: If there is constant extraction of the room in which the re is located, no

additional provisions are necessary.

What is creosote?

Creosote is a tar-like deposit which is left in the chimney. It is formed in poor combustion conditions when burning wood (damp wood, pinching off the air supply to the stove or burning impregnated or painted wood for example). Creosote ignites at approx. 500°C. This temperature can easily be reached if the re is raging. This means that deposits of creosote in your chimney could cause a chimney re.

What happens when wood is burnt?

The combustion process. The combustion of wood involves the following steps.

Drying The rst step is that the fuel (wood) dries out. Even at low temperatures (~ 100°C), any moisture still in the wood will evaporate. This drying procedure implies a signicant loss of energy if wood which is ‘too’ damp is burnt. The right degree of moisture is achieved after 1.5 - 2 years of drying. The moisture content is then 15 - 17%.

Decomposition

At moderate - high temperatures (150°C - 350°C), the decomposition process can be discerned. This is when the chemical structure of the fuel breaks down. This process involves the creation of volatile compounds such as carbon monoxide (CO), water vapour (H2O) and methane (CH4). In addition, substances which are volatile at decomposition temperature but condense at lower temperatures are often released. These are the tar-like components (this byproduct is also known as creosote, which is deposited in the chimney and cold parts of the stove in poor burning conditions).

Combustion of the products of decomposition The volatile compounds burn in the gas phase if O2 (air) is added. The ignition temperature of these volatile compounds is approx. 550°C.

Combustion of solid hydrocarbons The solid component that remains consists of pure hydrocarbons, which will burn at approx. 800°C if O2 (air) is added.
