It is
prohibited
to burn these and other unsuitable materials in your stove.
If materials other than the approved fuels of firewood or wood briquettes
according to DIN 51713 are burnt, this can lead to the formation of dan-
gerous gasses and disruption to the burning process right through to
deflagration.
The guarantee is rendered void if the ambiente a1/a2/a3/a4/a4 H

O/a5/a7/
a8 stove is operated using non-approved fuels.
Use small pieces of wood to get the fire going. Only used chopped wood as
a fuel that is no thicker than approx. 8 cm at its thickest point. The
optimal
length of the wood is
approx. 25 cm.
Do not add too much wood to the fire;
it is preferable to add small volumes of wood. When adding wood to the fire,
the embers must not be completely covered.

NEUTRALITY
Wood only releases as much carbon dioxide as it collected and trapped from
the air as a tree. It is irrelevant in this case whether the wood is burned or
rots in the forest – the carbon dioxide released always remains the same.
New trees absorb the carbon dioxide that is released from the wood during
burning – a closed natural carbon dioxide cycle is produced.
Conclusion: Nature remains in a state of equilibrium as a result of burning
wood. Germany has regulated the sustainable management of forests by
law. This obligation has led to a growth in the volume of wood because
the increase in wood grown in forests is on average 40% greater than the
volume of firewood and timber used.
5.1.1 STORING WOOD
In general, it is recommended to store firewood for approx. 2-3 years, the
wood should be protected from dampness and well ventilated (e.g. under a
roof overhang on a side of the building protected from the weather). Wood with
moisture content < 20% will be achieved significantly quicker with optimal
storage. Therefore, you should store your firewood already chopped because
the bark can prevent the moisture escaping from the wood. You should leave
a distance the width of a hand between the logs for good ventilation so that
the air can circulate properly and the moisture escaping from the wood can
be taken away by the air. A distance to the floor of approx. 20-30 cm should
be maintained underneath the stack of wood. Renewed absorption of moisture
due to precipitation (e.g. rain or snow) should be avoided. Storing wood in
garages, under plastic sheets or in poorly ventilated cellars is not recom-
mended because the moisture present in the wood cannot escape properly.
Use an easily obtainable wood moisture measuring device to check your fuel.
5.2 YOUR CONTRIBUTION TO ENVIRONMENTAL
PROTECTION
Whether your a1/a2/a3/a4/a4 H
2
O/a5/a7/a8 stove burns in an environmen-
tally friendly way is dependent to a large degree on how it is operated and
which fuel is used. The following advice should help you to operate your
stove in an environmentally friendly way:
• As far as possible, do not use any resinous wood (spruce, pine, fir).
These types of wood cause sooting of the stove panel to occur quicker
and there is an increase in flying sparks. Therefore, please only use
hardwoods (birch, beech, oak, wood from fruit trees) for safety reasons.
