ATTENTION :
During the operation of burner and the heat consumer unit, when there are
certain incompact sections, there could be smoke leakages, eventually through the flexible
hose, which connects the fuel transport auger and the main unit of the burner. It is strongly
recommended to make appropriate steps for stopping these leakages. Also the burner’s
thermal capacity should be adjusted, according to the current heat demand. Same process
could be observed at transition periods (autumn and spring) and especially in summer, when
the ambient temperature is relative higher that the operating temperature of the unit, as well
as the chimney’s draught is decreased.
COMMENTS :
At the period of fuel ignition an electric heater, positioned below the inclined grate’s
plate, is activated. Both the heater and the plate above are heated to high temperature
levels and certain precautions should be taken in order avoid any contact with and get
skin burned in case of combustion chamber manual manipulation. In case that manual
operation is required (for example for ash cleaning or fuel management)- self protective
measures and appropriate instruments should be used;
During the start-up operation of the burner, the fuel transport auger should be charged
(filled) with fuel – this is long lasting, time consuming period. In such case it is
recommended to plug the auger power supply cord into a common power supply wall-
plug and do the auger charge until fuel starts to drop from its outlet. After this charge
operation the auger’s plug should be connected to the operating plug of the main unit;
ATTENTION
:
the control board of the burner monitors the presence and adequate
operation of the transport auger and if the auger is not plugged in the main unit of the
burner, then the control board goes in alarm mode and the burner will not function. In
order to go in nominal operation mode it is necessary to plug the auger power supply in
the contact point on the main module and restart the burner – switch off and back on
the power supply;
EXPLANATION :
if the auger’s power supply cable has been disconnected from the
main unit of the burner (this situation is considered as alarm mode of the control board
of the burner)– i.e. the electric motor is malfunctioning or wiring problems) and the
burner has been switched on, then the control board indicates this mode by appropriate
message, shown on the display. The reset process should be performed : the auger
should be correctly plugged in the operating connect point on the main unit, the power
should be switched off and back on;
The burner operates by predefined working algorithm, programmed in the inerasable
memory chip on the control board. Optimal values of the parameters are defined by
default at production and in principal no change is required in order to run the unit;

Burner’s operating algorithm
The burner starts its nominal operation if the following conditions are fulfilled:
The main unit of the burner is installed at the heat energy consumer appliance;
Available power supply;
Activated “START” from display;
Installed temperature sensor for measurement of the temperature of the circulating
water –
in case the control module uses this type of thermal capacity control
operation
;
No alarm signals are available;
The fuel transport auger is charged and filled with fuel and bunker is charged with
fuel as well;
