be very hot.
Never throw the wood into the combustion chamber, as this will destroy the insulation mate-
rial.
Thereafter, close the door completely.
If the wood has the right moisture, it will ignite after approx. 20 to 45 seconds.
Only use wood with a moisture content of between 12 and 20%, or soot and tar will form in
the chimney, and cause the glass to become sooty. The moisture can be controlled using a
moisture meter.
• The maximum amount of fi rewood that may be placed inside reaches up to the metal air rail
at the back of the combustion chamber. This corresponds to 17 cm from the bottom of the
combustion chamber.
• When the fi re is well underway and the fl ames are light/yellow, the Air control handle can be
adjusted to the left, so that the desired combustion is achieved. (The operating range is from
the middle to the left, as seen from the front.) If you want a "slower" combustion, push the
Air control handle further to the left, depending on your needs and temperament. However,
never completely close the Air control handle, as this will result in inappropriate combustion,
suff ocation of the fi re and, in the worst case, a fl ue gas explosion.
• If there is a need for a little extra air to get the combustion going faster, the Air control
handle can, for short period, be pushed to the right into the lighting position (all the way to
the right, as seen from the front), but for max. 1 min.
• When the stove is in operation, and more fi rewood needs to be added, follow the steps
above.
3.7.3 Interferences, problems and solutions related to the adding of fi rewood
Issue:
• The glass becomes sooty
Causes:
• The fi re in the combustion chamber is not hot enough. Push the Air control handle to the
right, at a maximum to the middle position. This increases the amount of oxygen/operating
air, which burns the soot faster.
• The fi rewood is not dry enough – only use dry and clean wood.
• The chimney draft is not suffi cient – there is too little wood or it has been shut too far off
from the air.
• The lighting position is used for too long.

4.0. Safety

The surface of the stove as well as knobs, handle, window, smoke pipe etc. becomes very hot
when the stove is in use. Touching of these parts without necessary protection (glove or other
forms of protective material) can lead to burns.
Remember to make children aware of this danger and make sure to keep them away from the
stove when in use. For this purpose, TermaTech off ers various grates for protection of children
and pets.
5.0. Important and helpful advice

5.1. Lighting wood/-sticks

Kindling sticks is a term for small fi nely chopped wooden pieces that are approx. 18 to 20 cm long
and have a diameter of 2-3 cm. Wood like birch, beech, oak, ash, elm, pine wood and wood from
fruit trees are all suitable as fi rewood.
Note:Dont use alcohol, petrol, or other fl ammable liquids when you ignite the stove.

5.2. Firewood

Wood like birch, beech, oak, ash, elm, pine wood and wood from fruit trees are all suitable as
fi rewood.
Firewood should have a diameter of 7-10 cm and the length should not be more than the width of
the combustion chamber minus 4cm (width of the combustion chamber can be found under 11.0)
, otherwise it will get too close to the side of the stove. The most important thing for good com-
bustion is that the wood is dry (12-20% moisture) See section 5.8 Firewood storage.
If the fi rewood is too wet it is diffi cult to get it to burn, the chimney draught is non-existent, there
is a lot of smoke and the exploitation is lower as the water has to evaporate fi rst. Furthermore,
there may be damage to the stove and the chimney in the shape of shinning soot and tarry depo-
sits. At worst it can lead to a chimney fi re.
If the wood is too dry it will burn too quickly. The gasses in the wood are released faster than
they can burn and some go unburned through the chimney. This also gives a lower exploitation
and harms the environment. It is about fi nding a balance which is easy with a bit of practice.
