1. INTRODUCTION

1.1. PREFACE

We would like to congratulate you on your purchase of this modern BARBAS
fi replace insert. This quality product will give you years of heating pleasure as
you enjoy the play of the fl ames and the cosy glow of the fi 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 fi replace insert. We recommend you keep this manual
in a safe place for reference purposes.

1.2. SAFETY AND INSTALLATION INSTRUCTIONS

Safety

• Do not place fl ammable objects within 100 cm of the appliance. Pay special
attention to furnishings and ornaments around the fi re.

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

8

CUATRO-2 80CUATRO-2 70CUATRO-2 60

• Do not use your stove as a barbecue. This can cause (fl 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
fi tting a suitable cap to the chimney pot.

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

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

satisfi ed. The required constructive adaptations should be satisfi ed as well.

Installation instructions

• Wood and wood briquettes may be stoked in the stove.

Coals can’t be burned in the fi re.

• Never use the heater to burn rubbish.

• Please read all instructions / stickers on and around the appliance.

• Please also study the directions for use before using the appliance for the
fi rst time. When you fi rst fi re up your appliance, there are a number of extra
points you should take into account. See section 5.

• 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 fi tted
correctly to the brackets at the top of the fi re, the internal panels are fi xed to
the walls and the stones on the bottom have not moved. Check if there are
no foreign objects in the appliance.

• 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 fi re can then become over-heated.

This may damage the metal fl ue gas fl ap.

• The appliance may only be set up if the appliance and location meets the

- national and local installation regulations;

- local fi re brigade regulations and required architectural provisions.

3. INSTALLATION INSTRUCTIONS

3.1. FITTING THE FIREPLACE

When fi tting one of these fi replace inserts local and/or national regulations
relating to fi re safety must be followed. In case of doubt, consult the fi re safety
department of the local fi re brigade, particularly if the fi re is to be fi tted in a home

with walls and/or fl oors containing fl ammable material.

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

3.2. CHIMNEY

If no chimney is immediately available, have one fi tted by a recognised specialist
only. The chimney must be compliant with local regulations and is particularly
important because it has a signifi cant bearing on the function of the appliance.

Basic rules:

• A chimney for an open fi re is not, by defi nition, suitable for a closable model
(i.e. an appliance with doors). As a closed appliance draws in much less

(cold) air, the smoke is hotter. Please have your chimney inspected to see
whether it is suitable for a closable appliance.

• 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 fl 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.

• The internal diameter must not be less than that of the appliance at any point
(even at the end of the pipe).

• Avoid bends at all costs. The maximum deviation from the perpendicular is
45°.

• Both the dimensions and the construction must meet stringent construction
standards. Your recognised specialist will be pleased to assist.

• Contact your fi re insurer to make sure that your policy is in order.

14

CUATRO-2 80CUATRO-2 70CUATRO-2 60

3.3. FITTING

A fi replace insert can be fi tted in the newly-built or existing chimney breast
of an open fi re. When fi tting, both fi re safety and operational safety must be
safeguarded. The fi tter is responsible for this.

General guidelines:

• If there is a wooden beam above the fi tting location, heat must not radiate
directly onto it. An insulation plate must be hung below the beam, leaving an
air gap between it and the beam of at least 1 cm.

• Always use (white) unbound ceramic insulation wool. Bound material
(yellow), such as glass and rock wool, spreads an irritating smell on heating,
causes excess smoke and is unsuitable for high temperatures (insulation
requirements: temperature ≥ 700°C, density 80 kg/m

3

).

• Have any electrical connection for the Perma Air ® convection fan box carried
out by a professional electrician.

Note ! : The fan set should be connected to an earthed wall socket.
This socket must remain accessible at all times.

• Before fi tting, remove the door to protect the glass.

16

CUATRO-2 80CUATRO-2 70CUATRO-2 60

3.3.1. Aeration / ventilation

A fi replace insert 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, of directly from outside, due to the natural draught of the chimney.

• Combustion air from the living-room:

The air inlet openings are located behind the operating fl ap. When using
the appliance, please ensure there is a suffi cient supply of fresh air:
minimum 150 cm

2

opening in the room where the fi 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 fi t a fl ue gas fan.
The type of fl ue gas fan is dependent on the capacity of the mechanical
ventilation system. Always consult your fi 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. This will not only
avoid poor combustion, but will also prevent fl ue gases being sucked from
the appliance into the room.
Should creating an extra ventilation opening prove insuffi cient, it is then
necessary to fi t a fl 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.

17

CUATRO-2 70CUATRO-2 60 CUATRO-2 80

- Appliance without substructure fan box (convection fan):
The Ø125 mm (external) air supply connection is located in the appliance

and is accessible by fi rst removing a round disc at the bottom.
Mount then the connection ring (Ø126 mm internal) supplied (see section

3.5 and 4.1) and make a combustion air supply to the outside.
For example with a Ø125 mm fl exible aluminium pipe.

- Appliance with substructure fan box (convection fan):
Use the Ø125 mm (external) air supply connection at the left of the fan
box. Fit a rigid or fl exible pipe measuring Ø125 mm between this air
supply connection and the “outside air supply opening in the wall/fl oor”.

3.3.2. Fitting in an existing chimney breast

• Remove the existing fi re basket or stoking stones and remove the shut-off
fl ap. The chimney must be intact and must not be damaged during fi tting.

The chimney breast opening must be big enough for a gap of 1 - 3 cm to be

left all round the appliance. Clad the chimney breast opening from the inside
with a ceramic wool fi reblanket or similar (see section 3.3).

• Extend the existing chimney so that it ends at the appliance’s smoke outlet.
To do this, use a fl exible, double-walled stainless steel chimney, for example.

• Slide the appliance into the chimney breast opening. Seal the smoke
outlet where it joins the chimney so that no soot can accumulate above the
appliance under any circumstances.

• Level off the appliance so that the cover does not catch on the base.

• Fill any gaps around the appliance with a ceramic insulation wool fi reblanket
and position the frame (where supplied)

In the case of utilisation of convection air:

• Remove the detachable fl ap on the underneath and ensure that there is
at least 1 cm free space (niche) below the appliance. (See paragraph 3.5,
photos 1 and 2.)

18

CUATRO-2 80CUATRO-2 70CUATRO-2 60

3.3.3. Fitting in a newly-built chimney breast

• If required, a convection set can be added when installing the appliance.

• Appliance without fan box:
The use of a convectionset

is strongly recommended.

• Appliance with fan box:
The use of a convectionset is possible, but not mandatory.

• In the case of utilisation of a convectionset:
Carefully break out the “break-away openings” at the side (2x) or at the back

(1x) of the appliance.

• Use convection set:
The function of the convection set (option) is to improve the convection

through the appliance, resulting in effi ciency improvement and preventing
high temperatures in the chimney breast.
The set consists of: • 3 m alufl ex

• 2 exit grids (white)

• 2 collar adaptors Ø125 mm

• 4 hose clamps

• Assembly convection set:
° Secure the 2 collar adaptors to the appliance.

19

CUATRO-2 70CUATRO-2 60 CUATRO-2 80

° Now connect the fl exible hoses to the 2 collar adaptors (Ø125 mm) on

the top of the fi re and to the metal fi tting box on the air exit grids that are
being used (do not forget to fi t hose clamps).
° Ensure that the fl exible hose connections are gastight.
° The air exit grids cannot be fi tted until a few days later, once the
masonry has been pointed and allowed to dry. If one or more channels
are connected leading to other rooms, these rooms must be fi tted with
closable grids. These are available from your dealer, as well as the
fl exible hoses and clamps required.
° Within a range of 30 cm either side and 50 cm above the escape opening
(exit grids), there must be no fl ammable materials (e.g. wooden ceiling,
fi tted furniture).

20

CUATRO-2 80CUATRO-2 70CUATRO-2 60

• Clad the appliance on the top, sides and rear up to the front edge with an
approx. 10 cm thick ceramic isolation wool fi reblanket. Leave a few
centimetres clearance between the front of the chimney breast and the
appliance.

• Level off the appliance. Check that the slides do not catch on the base.

• Make a good seal between the smoke outlet from the appliance to the
chimney. See also 3.3.4.
Ensure that the entire fl ue is gas-tight.

• Ventilate the chimney, by placing ventilation openings at the top and bottom
of the chimney breast.

• If the fi re is to be placed against a bearing wall or against a wall containing

fl ammable material, an air gap of at least 20 mm should fi rst be created.
Before it a false wall, 100 mm thick, must be built of masonry or aerated
concrete.

• If the fi re is not placed against a bearing wall or a wall containing fl ammable

material, no false wall is necessary. Layers of insulation of at least 100-mm
thickness will then be suffi cient (class A1, DIN 4102-compliant).
See also section 3.3.

• After four weeks, your fi re will be ready for use.

5. STOKING UP FOR THE FIRST TIME

If you have had your chimney breast modifi ed or newly built, fi 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
fi replace insert 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
brake plate, fl ue gas fl ap, internal panels etc. are in the correct position.
They may have moved during installation.

The fi replace insert has a heat-proof fi 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 fi replace insert with a low fl 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 fi nish will now be properly hardened
and can be touched without damaging. The hardening process creates a nasty,
though harmless, smell/vapour.

Adequate ventilation is of the utmost importance.

6. USE

6.1. VENTILATION

Air is a vital component of the combustion process. Ensure that there is a

suffi cient supply of fresh air. For each kilo of wood that you put on the fi re (door
closed), 10 - 15 m

3

of extra air is needed. That means 50 m

3

per hour! As you

can see, a plentiful supply of air is essential.

6.2. GETTING THE FIRE GOING (Figure 2 and 3)

When you start the fi 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 slider (and/or the door) and air
supply slider. Use dry, fi ne wood and some scrunched-up paper or fi relighters to
start the fi re.

Locking slider all the way to the right (closed):
Flue gas fl ap operation works normally:

Control range of secondary and tertiary air supply

Combustion air supply slider

When setting the fi re, move the locking slider all the way to the left. 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 fi re.

Prevent white glow and over-fi ring.

6.3. INSTRUCTIONS WHILE STOKING

After approx. 10 minutes, the fi re will be burning fi ercely. You can now top it up
with a few larger blocks of wood. Move the locking slide all the way to the right
when the 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 fi re burns quietly.

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

35

CUATRO-2 70CUATRO-2 60 CUATRO-2 80

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 fi re with fuel, two blocks measuring 30 cm long and 30 cm
perimeter is suffi cient. Do not add more fuel until the previous fuel has burned
down to the charcoal stage.
The fl 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 fi ring up
the fi re when there is no wind, or in foggy/misty conditions.

Smoke development

Your fi re 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 fi re is situated.

Use of the fi re

Your fi re is suitable for periodic use.

The fi re 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 fi re, 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 fi re. Any alteration to your fi re, of whatever
nature, will also invalidate your warranty.

6.4. 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 fi re is at its most economical when:

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

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

• 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.

Note ! : Keep the bottom at the front as free of ash as possible.
Every 2 or 3 times you replenish the fi re, push the ash at the
front several centimetres towards the back. In this way, the fi re
will be well aerated as it burns.

6.5. CLEANING THE WINDOW

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

Continuous stoking with the primary air supply open (combustion air

supply slider is fully over to the “ + “ position) (air via rear of wood

rack, with outlet just above the vermiculite bottom plate) causes a

fi ercely white-hot fi re that can damage parts of the fi replace.

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 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 fi re burns well. The smoke generated should be translucent
or white and the windows of the fi re will remain clean. We recommend that
you do not ‘pinch off’ your fi re (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 fi re is burning. Doing so improves the
performance of your fi re 8 - 10 times, benefi ting the environment and the
heat in your home (less topping up, see section 7.2). You will also prevent fi re
damage from any particles the fi re ‘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 a fi 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 fi re with water - let it burn out. The part of the inner
lining that is in direct contact with the fi re is clad with cast iron sections or fi re­resistant material. Sudden changes in temperature may lead to it deforming
or cracks appearing.

38

CUATRO-2 80CUATRO-2 70CUATRO-2 60

• 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 fi re.

• 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.

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 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
fi re achieves output of 75% and thus falls into the category of high-output/
low emissions fi res. 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 fi 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 fi re.

39

CUATRO-2 70CUATRO-2 60 CUATRO-2 80

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

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

• Using too much wood.
This is a problem if your fi replace insert 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 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.

40

CUATRO-2 80CUATRO-2 70CUATRO-2 60

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: length = 30 cm; outline 30 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 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 a fi re with this is completely forbidden. To

re-iterate: the combustion gases released by these materials are aggressive
and will attack your fi replace insert and the environment.

• Paraffi n-containing open fi re lighters are not suitable for a closed fi re. A
closed fi re generates more heat than an open fi re, 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.

The Cuatro-2 is not suitable for coal fi ring.

41

9. AMOUNT OF FUEL

9.1. AMOUNT OF FUEL

Each appliance is constructed for a certain maximum amount of fuel. Remember
that the more fuel you put into your fi re, 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.

If you have chosen the right appliance for your room, it will provide suffi cient
heat with a single layer of wood blocks (a wood block is approx. 30 cm long and
30 cm around the edges).

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

You can best vary the capacity of your appliance with the amount of fuel.

Example:

The fi re has an output of 10 kW and an effi ciency of 75%:

Wood: 3 blocks, each around 1 kg
Briquettes: 5 briquettes, each around 0.5 kg

Your fi re has an output of 6 kW:

Wood: 2 blocks, each around 1 kg
Briquettes: 3 briquettes, each around 0.5 kg

9.2. HEAT RADIATION

The table below shows the temperatures which can theoretically be achieved by
burning wood.

Heat radiation

Sort of fuel kWh/kg

Dry wood (average) 4.3

The heating value of wood (18.7 MJ/kg at 0% humidity) is not affected by the
sort of wood. What does make a difference is the relative humidity of the wood
(15.6 MJ/kg at 15% humidity).

14. FREQUENTLY ASKED QUESTIONS

How often should I have my chimney swept?

At least once a year. If you use your fi re 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 fi replace insert have better output than an open fi re?

Yes, a fi replace insert has between 7 and 8 times the effi ciency of an open fi re.
(See also sections 7.2 and 7.3)

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 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 fi re 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, a fi re 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 a fi re with an output of around 7 kW. For each subsequent 10 m3, add on

0.6 kW.

In a relatively well-insulated house, the general rule is that in a room of 80 m3,
an appliance of 5.5 kW is adequate, and for each subsequent 10 m3, you need
to add a further 0.4 kW.

56

CUATRO-2 80CUATRO-2 70CUATRO-2 60

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

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

At what temperature does the convection fan cut in?

If the appliance is fi tted with a convection fan, this can be regulated using an
built-in dimmer with an integrated on-off switch.

The fan does not have any automatic regulation based on the appliance
temperature.

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 fi 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 fi 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 fi re quicker and the smoky period will be
shorter.

If you leave the fi re 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%).

57

CUATRO-2 70CUATRO-2 60 CUATRO-2 80

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 fi re 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 rear of the wood rack, just above the

bottom plate (burning fl oor).

• 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 fi re 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

fi replace 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 fi re is located, no

additional provisions are necessary.

58

CUATRO-2 80CUATRO-2 70CUATRO-2 60

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 fi re or burning impregnated or painted wood for example).
Creosote ignites at approx. 500°C. This temperature can easily be reached if the
fi re 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

2

O) 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 fi re 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.
