Firing in general
Rapid or erce heat
Rapid or erce heat is obtained by burning many small pieces of wood.
Maximum amounts of fuel:
The maximum allowed amount of fuel per hour is:
Model Wood
HWAM 4500 2.4 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 stove has been approved for intermittent use.
Typical re-ring interval
Typical re-ring interval at nominal performance:
Model Re-ring interval Wood
HWAM 4500 45 min. 1.1 kg
Long burning times
For the slowest possible combustion, turn the regulator counter-clockwise (to the left). By turning the regulator
all the way to the left, the stove receives no primary air (the air that comes through the grate). The stove cannot
be lit after a new ring without the regulator being turned to the right, which allows primary air to enter the unit.
After lighting, always check that persistent ames develop in the wood. If not, the air supply is too limited
and must be increased by turning the regulator to the right (clockwise).
Insufcient ring
If the reproof materials in the combustion chamber are blackened after a re, then the stove is polluting,
and the automatic air ow regulation system is malfunctioning. Therefore, more air must be supplied by
turning the regulator 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 inefcient combustion, plenty of smoke, and soot. Furthermore, the heat will dry
the wood, not heat up the room.
• The re should only be stoked with a little wood at a time.
You achieve the best combustion by starting up a re often and using only a little wood. If you use
too much rewood, 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 re. Otherwise they build up soot in the chimney (constituting
a chimney re risk) or will be released in a non-combusted state into the environment. The wrong
amount of air supply creates inefcient combustion and a modest effect.
• Don’t savour the re during night time.
We advise against adding re 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 re.
Cleaning the glass
We recommend wiping the glass after a re. This is best done using a paper towel.
