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: • ECO 40: length: ca. 15 cm
outline: ca. 30 cm
• ECO 52: length: ca. 15 cm
outline: ca. 35 cm
• ECO 55: length: ca. 15 cm
outline: ca. 40 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 • 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 • ammable waste. Stoking a ! re with this is completely forbidden. The
combustion gases released by these materials are aggressive and will attack
your ! replace insert and the environment.
• Paraf! n-containing open ! re lighters are not suitable for a closed ! re. A
closed ! re generates more heat than an open ! re, thus the paraf! 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 appliance is not suitable for coal ! ring.
