Firing in general
Rapid or fierce heat
Rapid or fierce heat is obtained by burning many small pieces of wood.
Maximum amounts of fuel:
The maximum allowed amount of fuel per hour is:
Wood: 2.5 kg
If these limits are exceeded, the stove will no longer be covered by the factory guarantee, and
it may also become damaged due to excessive heat, the glass may turn white, for example..
The stove has been approved for intermittent use.
Typical re-firing interval
Typical re-firing interval at nominal performance
Wood: 45 min (1.2 kg)
Prolonged burning time
You will obtain the longest burning time if you reduce the air supply to an absolute minimum
when the flames are dying, as this will prolong the ember phase. When you add new firewood,
set the air supply at about 40% to allow the wood to catch fire.
How to achieve the best combustion
• Use clean and dry wood
Wet wood results in inefficient combustion, plenty of smoke, and soot. Furthermore, the
heat will dry the wood, not heat up the room.
• The fire should only be stoked with a little wood at a time
You achieve the best combustion by starting up a fire often and using only a little wood. If you
use too much firewood, it will take some time before the temperature reaches a level where
you achieve a good combustion.
• Make sure there is the right amount of air
You should also make sure that there is plenty of air – especially in the beginning - so the
temperature in the wood burning stove climbs quickly. In this way the gasses and particles
released during the combustion will be consumed by the fire. Otherwise they build up soot
in the chimney (constituting a chimney fire risk) or will be released in a non-combusted state
into the environment. The wrong amount of air supply creates inefficient combustion and a
modest effect.
• Don’t savour the fire during night time
We advise against adding fire wood to your stove and reducing the air supply at night in
an attempt to still have some embers left in the morning. If you do so, large amounts of
hazardous smoke will be emitted, and your chimney will be exposed to unnecessarily large
amounts of soot with the risk of a chimney fire.
