Note
:
If we do something wrong, we answer the question CONFIRM CHANGES? (Confirm
changes) by NO (no).
Similarly we can change the time parameters TT6 - pellets burning time (geared motor pause in
the normal cycle)
- Similarly we can change the desired parameters
- The light
RUN
indicates that the normal operating mode is on
Note
:
Do not try to change other parameters, except those above.
2.6. Adjusting the burner
If it is too high, decrease the pallets feeding time. If the temperature is too low, insert additional
air.
If the level of the pellets inside the burner is too low, verify the temperature of the combustion
gasesand and decresae the quantity of air and increase the quantity of pellets from the feeding times.
The quantity of the pellets feeding must be changed, using the mode described at point 2.5.1.
The criteria for perfect burning is the flame colour.
If the colour is dark yellow, mixed with smoke, probably the feeding with pellets is higher than
necessary and should be reduced at the parameters T4 şi T6 (decreased T4 and
/or increased T6). By
openning the air valve the combustion process is stable, without any waste (normally the valve is not
entirely open). If the valve is opened too much it is possible to throw the unburned pellets in the
boiler’s burning point.
If the initial feeding is too high it is likely for the burner (grate) to be plugged. The result is that
the first dose of pellets is larger than the required one, they are lighted up and the flame is recorded
by the photosensor, and the burner enters the operation mode before the pellets ignite (the entire
ignition dose). In this case, the initial feed time must be reduced by adjusting the T4 parameter.
Note:
When you adjust the burner, you need a device for measuring the combustion gases.

PELLETS BURNER
The adjustment of the capacity of the burner is made by
adjusting the pellets flow and the combustion air flow.
The fuel flow is adjusted by setting in the programmable
automaton the times of
pellets feeding
(cycle) and
pellets burning
(cycle).
The combustion air flow is adjusted by screwing in
/screwing off the bar
(1)
that presses the oneway valve
(2)
fig.27.
If the device does not work properly:
- verify the quality of the pellets (they must be
dustfree).
- if there are too many pellets inside the burner, adjust
the pellets feeding and adjust the combustion air intake
- verify the temperature of the combustion gases (140-
220ºC)
