HANDLING OF THE FUEL
SELECTING WOOD/FUEL
You can use any type of wood as fuel. However harder woods, such as beech or ash, are generally better for heating, as
they burn more evenly and create less ash. Other woods, such as maple, birch and spruce, are excellent alternatives.
PREPARATION
The best fuel is obtained where the tree has been felled and the wood sawn and split before May 1st. Remember to cut
the wood to match the size of the combustion chamber. We recommend a diameter of 6-10 cm. The length should be
about 6 cm shorter than that of the combustion chamber to leave enough space for air to circulate. If the diameter of the
wood is greater than the above, it should be split down its length. Wood that has been split dries faster.
STORING
You need to store the sawn and split wood in a dry place for 1-2 years before it will be dry enough to burn. Wood dries
faster if you stack it in an airy place. Before using it, it is a good idea to store the wood for a few days at room tempera-
ture. Remember that wood absorbs moisture from the air during autumn and winter.
MOISTURE
To avoid problematic impact on the environment and to ensure optimum operating economy, the wood should be per-
fectly dry before it can be used as fuel. If you use wood that is too damp, most of the heat it produces will be used up in
evaporating the water. The stove will accordingly not increase in temperature, nor emit heat to the room as a result. This
is obviously poor economy, and it will cause soot build-up on the glass pane, in the stove and in the chimney. Operation
using moist wood also pollutes the environment.
¬
Maximum wood moisture content should not exceed 20%. A moisture content of 15-18% will deliver best efficiency.
¬
An easy way of checking wood moisture content is to knock the ends of the two pieces of wood together. If the wood is
moist, the sound will be slightly muffled.
USE OF THE FOLLOWING AS FUEL IS ILLEGAL
NOTE: It is absolutely prohibited to fire with painted, pressure impregnated or glued wood, or sea driftwood. Nor should
you ever burn chipboard, plastics, or treated paper. These contain substances that are hazardous to human health, to the
environment, your stove, and your chimney. In short - make sure you only use proper wood.
CALORIFIC VALUE OF THE WOOD
The various woods have different calorific values. In other words,
for certain species of wood, you will need to use a greater quantity
to achieve the same heating performance. This Instuction
Manual assumes that you will be using beach, which has a
very high calorific value and is also the easiest wood to get
hold on. If you use oak or beech as fuel, you need to bear in
mind that these wood types have a greater calorific value
than for example birch. To avoid any risk of damage to the
stove, you should therefore make sure to use less fuel in
these cases.
