The combustion of the pellets, regardless of the power at which the boiler is operating, it
is necessary to adjust so that in the space at the top of the combustion chamber (shown in
the figure). This is achieved by adjusting the dosage of pellets and by the amount of air.
In the case the level of the flame begins to be lowered, it is necessary to extend the time
of dosing or the reduction of the amount of air. If we want to reduce thermal power, it is
necessary to reduce the amount of air. If it happens that the level of flame rises, we can
reduce the time of loading or increase the amount of air. To accurately determine the
parameters it is necessary to monitor the process of operation for at least an hour.
NOTE : Always, nominal or maximum power of burning wood pellets should be
observed, i.e. when pellet is burned on top of the burner. In this case, the decrease of
the heat power is performed by reducing the set boiler water temperature or set the
temperature of the room thermostat.
Warning: Be sure to make the analysis of the flue gases after the finish of installation of the
boiler. Measure the percentage of oxygen (O2).
