INTRODUCTION
Congratulations on your purchase of this modern Barbas appliance. This quality product
will provide you with many years of enjoyment due to the flame effect and warmth that it
provides.
This appliance is exempted under section 21 of the Clean Air Act 1993 and can be used
in accordance with the intended use as described in this manual in smoke control areas
in the UK.
Please read the instructions for use carefully before using the appliance for the first
time. Keep this booklet in a safe place.
“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
fixed 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 it is used in an “exempt” appliance (“exempted” from the controls which generally
apply in the smoke control area).
The Secretary of State for Environment, Food and Rural Affairs has powers under the
Act to authorise smokeless fuels or exempt appliances for use in smoke control areas in
England.
In Scotland and Wales this power rests with Ministers in the devolved administrations
for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981,
applies in Northern Ireland.
Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas
have been “authorised” in Regulations and that appliances used to burn solid fuel in
those areas (other than “authorised” fuels) have been exempted by an Order made and
signed by the Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act can be found here:
http://smokecontrol.defra.gov.uk/
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.

SAFETY
Do not place flammable objects within 150 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 filling 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
fire and burn intensely.
Do not approach the appliance with flammable 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 flue 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 fires! 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 flue and combustion air supply
are cleaned and inspected annually by a Barbas dealer/specialist.
The safe operation of the appliance will thus remain guaranteed.

Instructions for use
Cuatro-3 57
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 (flammable)
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 fireguard 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 satisfied. The required constructive adaptations should be
satisfied as well.

USING THE APPLIANCE FOR THE FIRST TIME
4.1
GENERAL
Allow your home to dry properly, after you have had your chimney breast modified 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
first 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 first 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 flue/chimney is not blocked, for
instance by birds’ nests etc.

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 m3 of extra air is needed. That means about 35 m3 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.
The air drawn in from outside (opening in the external wall) may be fitted with a sliding
grille or flap. Ensure that the flap 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. 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 (and/or the door) and air supply slider. Use
dry, fine wood and some scrunched-up paper or firelighters to start the appliance.

Cuatro-3 57
When setting the appliance, turn the locking all the way to the right.
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 appliance.
Prevent white glow and over-firing.
5.3 INSTRUCTIONS WHILE STOKING
After approx. 10 minutes, the appliance will be burning fiercely. You can now top it up
with a few larger blocks of wood. Turn the locking all the way to the left 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 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
efficient (more heat, less topping up).
Control range of primary air supply (by grate)
Control range of secondary and tertiary air supply
Combustion air supply slider
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 significantly 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
30 cm ê perimeter is sufficient. Do not add more fuel until the previous fuel has burned
down to the charcoal stage. This is after approximately 45 minutes. The flames are then
almost no longer visible. Do not leave the door open longer than necessary.
If there is insufficient burning material in the firebed to light a new fuel charge, excessive
smoke emission can occur. Refuelling must be carried out onto a sufficient 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 fire bed, add suitable kindling to prevent excessive
smoke.

Instructions for use
Cuatro-3 57
Weather conditions
In order to reduce pollution and any other inconvenience, we advise not firing 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.
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 flue gas fan if the flue is fitted with one.
Spare parts
Any replacement parts must be new, original parts. Use of non-original/reconditioned
parts will invalidate your warranty.
Modification
Do not make modifications to your appliance.
Any alteration to your appliance, of whatever nature, will also invalidate your warranty.
Only open the door for filling 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 fiercely white-hot fire that can damage the grate and other
parts of the appliance.
Increasing the draught in the appliance.
If the flue has too much resistance, so that the exhaust gases are not properly disposed
of, one can increase the draught in the appliance.
Instructions for use

Cuatro-3 57
Increasing the draught:
• Remove the flue gas flap by lifting it slightly, tipping it backwards and removing it.
• Bend the strips, L and R, on the retardant plate (brake plate) holder completely
backwards. As a result, the opening for the discharge of the flue gases increases.

5.4 HEATING ECONOMICALLY
The most environmentally-friendly and economic way of heating with wood is to have
your fire hot but calm. The ash should appear to glow a soft red-orange and should not
glow like a blacksmith’s fire. 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 fire should be homogeneous, and the fire 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
21
Cuatro-3 57
5.6 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. Wood can only be classified 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 fire).
• Keep the door shut when the appliance is burning. Doing so improves the
performance of your appliance 8 - 10 times, benefiting 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 floor contains flammable material, an extra floor 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 fire-resistant material.
Sudden changes in temperature may lead to it deforming or cracks appearing.
• Chimney fire.
If, despite all the precautions, a fire should occur in the chimney (you generally notice
that because of a roaring sound in the chimney), do the following:
• Immediately shut the chimney flap (if fitted).
• Immediately shut the air supply to the appliance.
• Call the fire brigade (( 112).
• Quickly quench the fire in the appliance with sand or soda in order to prevent
smoke in your house.
• Never use water to put out the fire.
• Ventilate.
• If there has been a fire in the chimney, have it swept and inspected for damage
and leakage.

Instructions for use
Cuatro-3 57
5.7
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 insufficient 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 benefit directly by using less wood to achieve the same level of heat.
The environment benefits 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 flames. 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 fire).
Combustion really needs time. If combustion is too intense, there is insufficient time
for the fire 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.
PERMA AIR ® CONVECTION FAN (OPTION)
If the appliance is fitted with a Perma Air ® convection fan, it can be operated with the
wall-mounted dial (wall dimmer switch) near the appliance. This dial allows you to turn the
convection fan ON or OFF, and to control the speed of the fan variably.
5.8
Always use the convection fan when the appliance is in use.

FUEL
The appliance has been recommended as suitable for use in smoke control areas when
burning clean wood logs hereunder. All suitable fuels listed in Section 6.1 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: • Cuatro-3 57: length: c. 30 cm
outline: c. 30 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 flame, 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
flammable 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.
•
Paraffin-containing open appliance lighters are not suitable for a closed appliance.
A closed appliance generates more heat than an open appliance, thus the paraffin
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.
6.2 AMOUNT OF WOOD
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 fire. 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.

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 flow of air to the appliance.
• Wait 24 hours after stoking before emptying the
ashtray.
• Cleaning the glass
:
• Regularly clean the glass on the inside of the
appliance with glass spray or ceramic hob cleaner.
Attention !! If the glass is not cleaned on time,
this can result in becoming dull and
difficult, if not impossible, to clean.
• If the glass is broken or cracked, it must be
immediately replaced before operating the
appliance again.
Broken ceramic heat-resistant glass
may not be thrown away in a glass
container, but must be included in
normal household waste.
• Cleaning the appliance
:
• Wait for the appliance to cool down sufficiently
before cleaning. Never use scouring powder,
aggressive cleaners or fire polish on the appliance.
Use only a dry lint free cloth.
• Regularly remove any dust deposits from behind
the door by means of a vacuum cleaner.

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 fire 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 efficiency of an open
appliance. (See also Chapter 5.7.)
What is the difference between net capacity, gross capacity and efficiency?
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.
Efficiency 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 m3, you need an
appliance 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.
Can a wood-burning appliance/fireplace insert be connected to a central heating
installation?
The Barbas range does not have any appliances 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 fitted 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.
28
Instructions for use
Cuatro-3 57
How do I know if I’m heating correctly?
Follow the instructions in this manual.
The flames 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 fire 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 fire?
This probably means that the wood is damp. Remove the wood and replace it with dry
wood. If necessary, make a fire 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 flow 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 fit 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 flue gas fan is required for permanent extraction of the area in which the appliance is
placed.
The type of flue 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 fire.
What happens when wood is burnt?
The combustion process.
The combustion of wood involves the following steps:
Drying
The first 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 significant 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 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 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.
