7.2.2. Test run of stove
Start the stove and test all combustion levels (Auto, 4, 3, 2, and 1). During this process, it is
important to check that there is sufficient combustion airflow to the stove. The sign of a succes-
sful ignition process is that the flames are pale yellow after 15 minutes of operation – the flames
should also remain pale yellow if you turn the heat down. However, when adjusting to a lower
level, there will be a ‘conversion period’ given that the airflow is reduced and fewer pellets are de-
livered to the stove. This process will normally last for a few minutes, when the flames may burn
dark yellow or orange until optimal combustion is re-established (pale yellow flames).
7.2.3. Is the stove not burning cleanly?
If the stove settings are correct but the combustion produces dark flames, several factors may
be having an influence. Fuel, pellet type and chimney will be the most significant factors, and the
following section describes the relevant solutions.
The stove’s basic settings are based on a pure, pale pellet and a chimney with a draught of 12
pascals (like a standard wood-burning stove). If a different type of pellet is used (e.g. a dark, he-
avier pellet) or if there is insufficient draught in the chimney, it may be necessary to increase the
combustion airflow. You can make the relevant adjustments via the control panel. Go to the menu
for ‘Pellet type’ (see section 8.2.7 in the instructions for use). Level 1 is the standard setting, level
2 provides 10% extra air, and level 3 provides 20% extra air.
If this is not sufficient to achieve the combustion desired, and approved service technician/dea-
ler can increase the airflow even more using the hidden parameters in the control programme.
However, this should only be necessary in exceptional cases – 10% or 20% extra air should be
sufficient. If the stove receives too much air – possibly as a result of a chimney with excessive
draught – it is likewise possible to reduce the airflow in the combustion process.
