Operating the heat compartment damper - HWAM 3130
There is a damper at the back of the stove between the top plate and the heat compartment that opens
and closes the flow of convection air in the heat compartment. The supply of convection air can be opened
by moving the damper to the left and closed by moving the damper to the right.
We recommend that the convection damper is kept closed when fuelling the stove in order to heat up
and thereby store heat in the heat storage stones in the heat compartment as rapidly as possible.
Keeping the convection damper closed retains the heat stored in the heat storage stones as long as pos
-
sible. When the damper is opened, the heat from the heat storage stones in the heat compartment will
rapidly be transferred to the room.
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: 2.0 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-firing interval
Typical re-firing interval at nominal performance
Wood: 65 min
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 firing without the regulator being turned to the right, which allows
primary air to enter the unit.
If the regulator is turned 45º from its minimum position (i.e. set at 25% capacity), the stove can restart
following a new firing without further adjustment.
Insufficient firing
If the fireproof materials in the combustion chamber are blackened after a fire, then the stove is polluting,
and the Autopilot 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 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
