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: . 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:  min (, kg)
Prolonged burning time
The longest burning time is achieved by turning the air control knob counter-clockwise (to the left)
when the flames are about to die. This will ensure the longest period with embers. When adding
new firewood, always remember to check that the wood has caught fire properly. If not, the air
supply must be increased by turning the air control knob to the right. When the air control knob is
turned all the way to the left, no primary air will enter the wood-burning stove through the bottom
plate in the combustion chamber. The stove cannot be lit after a new firing without the air control
knob being turned to the right, which allows primary air to enter the unit.
If the air control knob is turned º from its minimum position (i.e. set at % capacity), the stove
can restart following a new firing without further adjustment.
Insucient firing
If the fireproof materials in the combustion chamber are blackened after a fire, then the stove is
polluting, and the HWAM
®
Autopilot™ is malfunctioning. Therefore, more air must be supplied by
turning the air control knob clockwise (to the right). It may also be necessary to burn more wood.
How to achieve the best combustion
• Use clean and dry wood.
Wet wood results in inecient 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 inecient combustion and a modest
eect.
• 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.
