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 90: length: c. 28 cm
• Wood briquettes without binder (see wood dimensions).
• Hard woods burn slowly and easily form charcoal; for example hornbeam, oak,
ash, beech, elm and birch.
Softwood burns with more fl ame, but forms less charcoal and radiates less heat.
Examples are spruce, pine, poplar and linden.
Unsuitable fuels are:
• Painted, bonded (chipboard, MDF etc.) or impregnated wood, plastic and other
fl ammable waste. Stoking an appliance with this is completely forbidden. The
combustion gases released by these materials are aggressive and will attack your
appliance and the environment.
• Paraffi n-containing open appliance lighters are not suitable for a closed appliance.
A closed appliance generates more heat than an open appliance, thus the paraffi n
will melt out of the blocks prematurely.
• Damp wood burns poorly, is unsuitable and produces too much smoke (including
in the room when you are topping up the wood), dirties the glass, leaves deposits
in the chimney and delivers about half the heat output of dried wood.
Do not burn coal, liquid fuels or burning gel in the appliance. The appliance is not desig-
ned 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 fi re. It may also damage your appliance
and chimney. BARBAS will not assume liability for damage caused by overheating.
Burning one layer of wood can lead to varying outputs. When used correctly, one load
will burn in around 45 minutes. Putting in too much wood at once can lead to the
appliance being overloaded and can cause excess smoke.
