Furthermore, due to its lower temperature, water vapour also has the
disadvantage of condensing in the flue tubes, which causes water droplets to
form. This can lead to undesirable consequences, such as severe corrosion and
the accumulation of soot. Wood that is too dry gasifies quickly, with the wood
burning too quickly compared to the available air supply. This results in
incomplete combustion, which has an environmental impact.
Storing wood
When buying wood, you should ensure that you have a sufficient quantity
stored for 1-2 years’ use. The wood needs to be in the form of split logs of the
right size and be stored under cover for a minimum of one year, depending on
the type of wood.
Nominal heat output
The fire’s nominal heat output is ? kW. This is attained at a minimum pressure
of 12 Pa. No more than three wooden logs should be placed in the fire at any
one time.
The fire is an intermittent-burning fire; please follow the instructions below to
ensure compliance with this specification.
Operating the fire
Lighting and loading wood
1. Place around 3 kg of dry, finely split wood in the centre of the combustion
chamber and arrange it in a pyramid shape. Light the wood with the help of two
fire-lighter cubes.
2. Leave the door open by around 2 cm for the first 8-10 minutes – under
supervision – and open the air valve fully (slide it all the way to the right).
3. If necessary, push the air valve in during the lighting process.
4. When the fire has burned down to embers (i.e. when there are no longer any
flames), carefully open the door so as not to disturb the ashes, and spread the
embers out into an even layer.
5. Place three equal-sized pieces of wood (approx. 2.6 kg) in the combustion
chamber. Two pieces should be placed on top of the embers parallel to the front
