Instructions for use
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 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 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:
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.

2 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
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.

7
Cuatro-3 90
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 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.

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.
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.
Locking all the way to the left (closed):
Flue gas flap operation works normally:
Door open Pin comes forwards Flue gas flap open
Door closed Pin is pressed in by the door Flue gas flap closed
Locking all the way to the right (open):
Flue gas flap always remains fully open !!
Locking for operating pin of flue gas flap (inside of door).
Locking closed (turned to the left) Locking open (turned to the right)
close open

16
Cuatro-3 90
Instructions for use
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).
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, three blocks measuring ca. 28 cm long and
30 cm
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
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 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.
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.

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.

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.
