The Barbas Unilux-6 265 Three-sided has been recommended as suitable for use in smoke control areas when burning wood logs.

The appliance, when sold into the UK market, include a factory-installed modiﬁ ed air slider to ensure compliance with smoke emission requirements within smoke control areas.

Study this manual carefully before using the ﬁ replace. We recommend you keep this manual in a safe place for reference purposes.

The pictures in this Installation Instructions are made from a variant of this appliance.

Although the dimensions of the appliance on the pictures may differ from reality, the actions and instructions shown are fully valid for the appliance described here.

See the “Instructions for use” for the operation of the appliance

The “Instructions for use” is provided separately by the appliance.

“The Clean Air Act 1993 and Smoke Control Areas”

Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any ﬁ xed boiler if located in a designated smoke control area. It is also an offence to acquire an “unauthorised fuel” for use within a smoke control area unless it is used in an “exempt” appliance (“exempted” from the controls which generally apply in the smoke control area).

In England appliances are exempted by publication on a list by the Secretary of State in accordance with changes made to sections 20 and 21 of the Clean Air Act 1993 by section 15 of the Deregulation Act 2015.

In Scotland appliances are exempted by publication on a list by Scottish Ministers under section 50 of the Regulatory Reform (Scotland) Act 2014.

In Northern Ireland appliances are exempted by publication on a list by the Department of Agriculture, Environment and Rural Affairs under Section 16 of the Environmental

Better regulation Act (Northern Ireland) 2016.

In Wales appliances are exempted by regulations made by Welsh Ministers.

Further information on the requirements of the Clean Air Act can be found here: https://www.gov.uk/smoke-control-area-rules

Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of smoke control areas and you can contact them for details of Clean Air Act requirements.

2 SAFETY

Do not place ﬂ ammable objects within 100 cm of the appliance.

Pay special attention to furnishings and ornaments around the appliance.

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

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

Do not approach the appliance with ﬂ ammable materials or liquids.

Any work with solvents, adhesives etc. in the space heated by the appliance can be very dangerous.

It is not allowed to connect the appliance to a ﬂ ue which is already connected to another appliance.

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 dealer or other specialist company.

Avoid chimney ﬁ res! Have your chimney swept at least once per year - more often if you use your appliance a lot. Prevent excessive deposits of soot inside the chimney by not burning freshly-cut wood. Instead, burn clean, dry chopped wood.

Ensure that the room in which the appliance is situated has adequate ventilation.

It is essential that the appliance, the ﬂ ue and combustion air supply are cleaned and inspected annually by a Barbas dealer/specialist.

The safe operation of the appliance will thus remain guaranteed.

8 Instructions for use

UNILUX-6 265 Three-sided

The appliance must never be used with the door open or the door glass removed.

Wood and wood briquettes may be stoked in the appliance.

Coals can’t be burned in the appliance.

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

Never use the appliance to burn rubbish .

Do not use your appliance as a barbecue. This can cause (ﬂ ammable) fat deposits to be left in the chimney and hastens the chimney becoming clogged.

Ensure at all times that children and other people who are not aware of the operation of a wood-burning appliance are only in the vicinity of the appliance exclusively under supervision.

Use a ﬁ reguard to protect the people and children mentioned above against possible burns.

The appliance is suitable and approved for intermittent use.

The appliance can be taken in operation if national and local regulations are satisﬁ ed. The required constructive adaptations should be satisﬁ ed as well.

4 USING THE APPLIANCE FOR THE FIRST TIME

4.1 GENERAL

Allow your home to dry properly , after you have had your chimney breast modiﬁ ed or newly built. Walls which have not been allowed to dry properly are a magnet for dust such as any smoke particles created when stoking up the appliance 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, lamps 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).

The appliance is coated with a lacquer layer resistant to high temperature.

During the ﬁ rst hours of operation, the burning in of the lacquer may result in an unpleasant smell. This is harmless, however.

To speed up the process, the appliance should be allowed to run for a few hours at the correct heat level, with adequate ventilation for the room in question.

After using your appliance for the ﬁ rst few times, you may be aware of a light deposit on the inside off the glass. This is caused by the paint curing. Once your appliance has cooled down, this deposit can be removed with glass cleaner or ceramic hob cleaner.

At the start of the heating season, check that the ﬂ ue/chimney is not blocked, for instance by birds’ nests etc.

• Check that all grates in the ﬁ replace are open.

Instructions for use 13

UNILUX-6 265 Three-sided

5 USE

5.1 VENTILATION

If wood is to burn, it needs air. For each kilo of wood that you put on the appliance (door closed), 10 - 15 m 3 of extra air is needed. That means about 35 m 3 per hour!

Depending on how the appliance has been installed, the combustion air will either be drawn directly from outside or from the living room itself. If the air is drawn in from the room, it must be ventilated by an opening in the external wall.

If the combustion air is led outside through a pipe, we recommend that a sealing valve is ﬁ tted in this pipe. This prevents condensation forming in the appliance when it is not in use. Ensure that the ﬂ ap is always open before using the appliance.

5.2 GETTING THE APPLIANCE GOING

When you start the appliance, the chimney is still cold and there is little draught.

Before the ﬁ re is lit, turn the operating handle completely to the right (maximum air supply). Open any chimney valve and the valve in the external combustion air pipe.

Place 4 wood blocks in the combustion chamber and place several fi re lighting sticks on them diagonally. Place 2 fi re lighting blocks between the fi re lighting strips. Ensure that fi re lighting strips are placed above the fi re lighting blocks. Refer to the illustrations below. Light the fi re lighting blocks and close the door as soon as they are well lit. After approximately 20 minutes the wood blocks will be completely lit. Leave the door closed as long as fl ames are visible. The appliance can be loaded again as soon as all of the fl ames have disappeared.

Attention: If the door is opened during the lighting process, while all of the wood has not yet been burned, smoke can escape.

Only open the door when you need to load more wood.

14 Instructions for use

UNILUX-6 265 Three-sided

5.3 INSTRUCTIONS WHILE STOKING

Using the air supply slider you can adjust the air supply for further combustion.

Make sure the appliance burns quietly.

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

Instructions for use 15

Centre position

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 signiﬁ cantly reduces consumption of fuel and allows new wood to catch light easier.

When loading the appliance with fuel, two blocks measuring ca. 30 cm long and

This is after approximately 45 minutes.

Do not leave the door open longer than necessary.

The maximum amount of fuel speciﬁ ed in this manual should not be exceeded, overloading can cause excess smoke and damage to the appliance.

Refuelling on to a low ﬁ re bed

If there is insuffi cient burning material in the fi rebed to light a new fuel charge, excessive smoke emision can occur. Refuelling must be carried out onto a suffi cient quantity of glowing embers and ash that the new fuel charge will ignite in a reasonable period. If there are too few embers in the fi rebed, add suitable kindling to prevent excessive smoke.

Weather conditions

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

Smoke development

Your appliance 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 appliance is situated.

Use of the appliance

Your appliance is suitable for periodic use.

16 Instructions for use

UNILUX-6 265 Three-sided

The appliance 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 appliance, ensure a good supply of fresh air, particularly if the combustion air is drawn from the room itself. Turn on the fl ue gas fan if the fl ue is fi tted with one.

Spare parts

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

Modiﬁ cation

Do not make modiﬁ cations to your appliance.

Any alteration to your appliance, of whatever nature, will also invalidate your warranty.

Only open the door for ﬁ lling and lighting the appliance 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 ﬁ ercely white-hot ﬁ re that can damage the grate and other parts of the appliance.

5.4 HEATING ECONOMICALLY

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

Your appliance is at its most economical when :

• Using dry and clean wood (as described further in Chapter 6).

• Always ensure even combustion. Stoke with the primary air regulator closed.

To do this, place the combustion air supply slider in the centre position.

• The bed of the ﬁ re should be homogeneous, and the ﬁ 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.

5.5 CLEANING THE WINDOW

After several burning hours, a light deposit may form on the inner side of the window.

Once the appliance has cooled down, this deposit can be removed using glass cleaner or ceramic hob cleaner.

Instructions for use 17

UNILUX-6 265 Three-sided

5.6 INCREASE THE FLUE DRAUGHT

If there is too much fl ow resistance in the chimney, causing insuffi cent fl ow of the fl ue gasses, one can increase the chimney draught.

To do this, remove the upper bafﬂ e from the appliance and break out with a pair of pliers one or metal strips from the bafﬂ e by moving the strip(s) back and forth until it breaks.

(See ﬁ gures hereunder.) If necessary use a saw or grinder to detach the strips.

Subsequently, replace the bafﬂ e in the appliance.

To reduce the chance of accidental escape of smoke, it is strongly adviced to follow the ﬁ ring instruction as stated in 5.2.

18 Instructions for use

UNILUX-6 265 Three-sided

5.7 GENERAL HEATING 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. W ood can only be classiﬁ 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 appliance burns well. The smoke generated should be translucent or white and the windows of the appliance will remain clean. We recommend that you do not ‘pinch off’ your appliance (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 ﬁ re).

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

• Avoid lighting an appliance 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 appliance with water - let it burn out. The part of the inner lining that is in direct contact with the appliance is clad with ﬁ re-resistant material.

Sudden changes in temperature may lead to it deforming or cracks appearing.

• Chimney ﬁ re.

If, despite all the precautions, a ﬁ 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 ﬂ ap (if ﬁ tted).

• Immediately shut the air supply to the appliance.

• Call the ﬁ re brigade ( ( 112).

• Quickly quench the ﬁ re in the appliance with sand or soda in order to prevent

smoke in your house.

• Never use water to put out the ﬁ re.

• Ventilate.

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

and leakage.

Instructions for use 19

UNILUX-6 265 Three-sided

5.8 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 insufﬁ 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 appliance achieves output of 75% and thus falls into the category of high-output / low emissions appliances.

This means that you beneﬁ t directly by using less wood to achieve the same level of heat.

The environment beneﬁ ts as well: a well-stoked, high-output appliance means less pollution and fewer odours.

Adverse effects on the output are:

• Burning the appliance 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 appliance.

• Excessive chimney draught.

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

The appliance cools and the combustion quality decreases.

• Using too much wood.

This is a problem if your appliance 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 ﬂ ames. This has an extra impact on the environment.

• Admitting too much air under the fuel (combustion air supply slider is than fully over to the “ + ” position). Combustion is raised to high intensity (like a blacksmith’s ﬁ re).

Combustion really needs time. If combustion is too intense, there is insufﬁ cient time for the ﬁ re 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.

UNILUX-6 265 Three-sided

6 FUEL

The appliance has been recommended as suitable for use in smoke control areas when burning clean wood logs as stated hereunder. All other suitable fuels listed hereunder can be used outside smoke control areas.

6.1 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: • length : c. 30 cm

• outline : c. 25 cm ê

• Wood briquettes 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 ﬂ 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 ﬂ ammable waste. Stoking an appliance with this is completely forbidden. The combustion gases released by these materials are aggressive and will attack your appliance and the environment.

• Parafﬁ n-containing open appliance lighters are not suitable for a closed appliance.

A closed appliance generates more heat than an open appliance, thus the parafﬁ 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.

Do not burn coal, liquid fuels or burning gel in the appliance. The appliance is not designed for this. Use is dangerous and can lead to health damage and serious damage to the appliance.

Each appliance is constructed for a certain maximum amount of fuel.

Remember that the more fuel you put into your appliance, the hotter it will become and overheating may even occur. If this happens, there is a risk of ﬁ 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 and can cause excess smoke.

8 FREQUENTLY ASKED QUESTIONS

How often should I have my chimney swept?

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

Does a closed appliance have better output than an open appliance?

Yes, a closed appliance has between 8 and 10 times the efﬁ ciency of an open appliance. (See also Chapter 5.7.)

What is the difference between net capacity , gross capacity and efﬁ 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.

Efﬁ 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 appliance.

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 appliance not burning cleanly.

How much wood will I use?

That depends entirely on how you heat your room, what sort of appliance you have and the size of the room you are heating. As a general rule, an appliance used in accordance with our guidelines (no air under the fuel, topped up once an hour) each kg wood produces an output of about 3 kW.

In an averagely-insulated house, the general rule is that in a room of 80 m 3 , you need an appliance with an output of around 7 kW. For each subsequent 10 m 3 , add on 0.6 kW.

In a relatively well-insulated house, the general rule is that in a room of 80 m 3 , an appliance of 5.5 kW is adequate, and for each subsequent 10 m 3 , you need to add a further 0.4 kW.

Instructions for use 25

UNILUX-6 265 Three-sided

Can a wood-burning appliance/ﬁ replace insert be connected to a central heating installation?

The Barbas range does not have any appliances that can be connected to central heating installations. W e do not advise attempting it!!

How do I know if I’m heating correctly?

Follow the instructions in this manual.

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

Once the fuel 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 appliance 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 ﬁ re quicker and the smoky period will be shorter.

If you leave the appliance 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 should I do if the wood does not catch ﬁ re?

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

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 ﬂ 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 ﬁ t a check valve or damper. This may not be possible in all cases.

Can I leave my appliance 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 is closed and the secondary/tertiary air supply is open.

• Primary air is supplied through the grate in the bottomplate (appliance base).

• 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, on the upper side of the

combustion chamber.

Do not leave children unattended while the appliance 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 ﬂ ue gas fan is required for permanent extraction of the area in which the appliance is placed.

The type of ﬂ 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 appliance 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 appliance or burning impregnated or painted wood for example). Creosote ignites at approx. 500°C. This temperature can easily be reached if the appliance is raging. This means that deposits of creosote in your chimney could cause a chimney ﬁ re.

What happens when wood is burnt?

The combustion process.

The combustion of wood involves the following steps:

Drying

The ﬁ 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 signiﬁ 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 (H

O) and methane (CH

). In addition, substances which are volatile at decomposition temperature but condense at lower temperatures are often released.

These are the tar-like components (this by-product is also known as creosote, which is deposited in the chimney and cold parts of the appliance in poor burning conditions).

Combustion of the products of decomposition

The volatile compounds burn in the gas phase if O

(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 O

(air) is added.
