1 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 or recommended for exemption 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. The appliance, when sold into the UK
market, include a factory-installed modified air slider to ensure compliance with smoke
emission requirements within smoke control areas.
Study this manual carefully before using the fireplace. We recommend you keep this
manual in a safe place for reference purposes.
The images in this manual are made of a different variant of this appliance.
The depicted appliance may differ from your device, but the actions and instructions
shown are fully valid for the unit described here.
“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 unless 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:
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 flammable 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 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
ve
ntilatio n.
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.

9
UNILUX-6 40
Instructions for use
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.

4.2 INCLUDED
4 USING THE APPLIANCE FOR THE FIRST TIME
4.1 GENERAL
Allow your home to dry properly, after you have had your chimney breast modi!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 !rst hours of operation, the burning in of the lacquer may result in an unplea-
sant 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 !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 "ue/chimney is not blocked, for
instance by birds’ nests etc.
N.B. If any part is missing, please contact your dealer.

Instructions for use
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 m3of 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.
If the combustion air is led outside through a pipe, we recommend that a sealing valve
is fitted in this pipe. This prevents condensation forming in the appliance when it is not
in use. 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.
Before the fire 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.
5.2.1 Burning wood logs
Place 4 wood blocks in the combustion chamber and place several fire lighting sticks
on them diagonally. Place 2 fire lighting blocks between the fire lighting strips. Ensure
that fire lighting strips are placed above the fire lighting blocks. Refer to the illustrations
below. Light the fire 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 flames are visible. The appliance can be loaded again as soon as all of the
flames 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.

UNILUX-6 40
Instructions for use
5.2.2 Burning coal or briquetted smokeless fuels *)
Load the appliance with approx. 2 kg of coal or smokeless fuel briquettes, together with
a suitable !restarter (e.g. wood kindlings) and light it with a small !re starter block and
close the door. Keep the airslider throughout the whole burning process in the far right
position. The appliance can be reloaded with coal or smokeless fuel briquettes after
approx. 1 hour.
5.3 INSTRUCTIONS WHILE STOKING
5.3.1 Burning wood logs
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
ef!cient (more heat, less topping up).
*) To burn coal or briquetted smokeless fuels the appliance must be equipped with a
multi-fuel kit.

Instructions for use
Combustion air supply slider
Control range of primary air supply (by grate)
Control range of secondary and tertiary air supply
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 signi!cantly reduces
consumption of fuel and allows new wood to catch light easier.
When loading the appliance with fuel, two blocks measuring ca. 15 cm long and 25 cm
ê perimeter is suf!cient. Only load again when the last "ames have disappeared. This
is after approximately 45 minutes. Do not leave the door open longer than necessary.
The maximum amount of fuel speci!ed in this manual should not be exceeded,
overloading can cause excess smoke and damage to the appliance.
5.3.2 Burning coal or briquetted smokeless fuels *)
After approx. 1 hour after starting the !re, stir the !rebed with a suitable poke and reload
with approx. 1 kg of coal or smokeless fuel briquettes. Keep the air slider in the far right
position (fully open).
The maximum amount of fuel speci!ed in this manual should not be exceeded, overloa-
ding can cause excess smoke and damage to the appliance
5.3.3 Additional remarks
Refuelling on to a low •re bed.
If there is insuf!cient burning material in the !rebed to light a new fuel charge,
excessive smoke emision can occur. Refuelling must be carried out onto a suf!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 !rebed, add suitable kindling to prevent
excessive smoke.
Weather conditions
In order to reduce pollution and any other inconvenience, we advise not !ring up the
appliance when there is no wind, or in foggy/misty conditions.
*) To burn coal or briquetted smokeless fuels the appliance must be equipped with a
multi-fuel kit

UNILUX-6 40
Instructions for use
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 combus-
tion 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.
Modi!cation
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 while burning wood logs 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.
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.

18
UNILUX-6 40
Instructions for use
To reduce the chance of accidental escape
of smoke, it is strongly adviced to follow
the firing instruction as stated in 5.2.
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.
5.6 INCREASE THE FLUE DRAUGHT
Attention: Not possible if the appliance is equipped with a 45 degrees chimney
connection.
If there is too much flow resistance in the chimney, causing insufficent flow of of the flue
gasses, one can increase the chimney draught.
To do this, remove the upper baffle from the appliance and detach the back part of the
baffle by moving this part back and forth until it breaks. (see figures hereunder)
Subsequently, replace the baffle in the appliance.
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.

19
UNILUX-6 40
Instructions for use
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. 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 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 !re).
• Keep the door shut when the appliance is burning. Doing so improves the
performance of your appliance 8 - 10 times, bene!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 "oor contains "ammable material, an extra "oor plate is required.
The appliance must not be operated with the air control or door left open except as
directed in this operating manual. Operation with the air control open or door left
open can cause excess smoke.
• 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 !re-resistant material.
Sudden changes in temperature may lead to it deforming or cracks appearing.
• 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 appliance.
• 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.

UNILUX-6 40
Instructions for use
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 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 appliance
achieves output of 75% and thus falls into the category of high-output / low emissions
appliances.
This means that you bene!t directly by using less wood to achieve the same level of he at .
The environment bene!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 "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 !re).
Combustion really needs time. If combustion is too intense, there is insuf!cient time
for the !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.
