generate air pollutants such as dust, carbon monoxide and hydrocarbons.

15.4 Expansion Noises

Steel expands upon heating and contracts as it cools, which can cause your stove to emit
audible expansion sounds. However, the design and construction of your stove takes this
into account and prevents this physical process from damaging the stove.

16. The Right Fuel

Only fuels which generate low quantities of smoke may be burned in stoves. For the
Akaba, only natural, untreated, beechwood logs, including the adherent bark, can be used
as fuel. Highly resinous coniferous wood (e.g. spruce, pine, fi r) tends to emit fl ying sparks
and leaves behind a fi ne layer of fl ue ash that can swirl up when the fi re box door is opened.
For the most attractive stove fi re, use beech wood logs. If other types of wood are
used, such as oak, birch, pine or larch, we recommend adding beech wood for
picturesque dancing fl ames. Brushwood and small pieces of wood are good
kindling materials.
he burning of e.g.:
- damp or moist wood (residual moisture content over 20%),
- varnished or plastic-coated wood,
- wood treated with wood preservatives,
- household waste, or
- paper briquettes (pollutants: cadmium, lead, zinc)
- any fl ammable fl uids (including methanol and ethanol) as well as any fuel pastes
or gels is not permitted.
Combustion of the materials listed above not only gives off unpleasant odours, but also
generates emissions that damage the environment and are harmful to health.

17. The Chemistry of Wood

Wood predominantly consists of the elements carbon, hydrogen and oxygen. It contains
virtually no environmentally hazardous substances such as sulphur, chloride and heavy
metals. As a result, complete wood combustion produces mainly carbon dioxide and water
vapour as the primary gaseous products as well as a small quantity of wood ash as the solid
combustion residue.
On the other hand, incomplete combustion can generate a number of pollutant substances,
such as carbon monoxide (toxic), acetic acid, phenols, methanol (toxic), formaldehyde,
soot and tar.

18. Contribution to Environmental Protection

Whether your Akaba burns in an environmentally-friendly or environmentally hazardous
manner depends to a large extent on how you operate it and the type of fuel you use (see
„The Right Fuel").
Use only dry wood; hardwoods such as birch and beech are most suitable
Only use small pieces of wood to light the fi re. They burn faster than large logs
and thus the temperature required for complete combustion is reached more
quickly.
For continual heating, adding smaller quantities of wood more frequently is more
effi cient and more ecological.
