8. REASONS OF IMPROPER OPERATION
Burner does not fire up the fuel:
Reasons:
 No fuel – check the fuel hopper and the feeder, if it is not blocked
 Too small startup dose – check the startup dose
 Burnt igniter – check the igniter
 Defective drive motor - check motor thermistors
Burner fires up but does not go into the first power
Reasons:
 Improper start-up dose – check the start-up dose
 Dirty or faulty photosensor – clean it or replace it
 Damaged outer thermostat in oil boilers or bakery ovens
Photosensor checking
See page 26.
Measuring readings:
 In darkness 0-5 units
 In full light 100 units
Overheating of inner feeder.
Reasons:
 Burner dirty with slag
 Weak chimney draft – chimney exhaust fan should be used
Damage of the feeder sensor– alarm can not be cancelled
Reasons:
 The most common reason of this breakdown is damage of thermo protection of a sensor,
which results in overheating of measuring part. Despite burner cooling off, the fault can
not be cancelled, in this case the measuring sensor should be replaced. In order to
verify if the sensor is faulty indeed, its resistance should be checked, it should be between
1-5 Ω. The resistance of a damaged sensor is about 100 kΩ.
Feeder filling
The inner feeder is designed to mix and feed fuel evenly. The reason of filling the inner
feeder can be:
 Bad setting of the inner feeder in relation to outer feeder – increase capacity of inner
feeder (service menu/ burner feeder)
 Gearmotor damage – replace the gearmotor
 Badly adjusted interval of feeder work – this value should not exceed 20s. (service menu /
burner interval)
Blower damage
Reasons:
 Blockade of blower blades – unscrew the blower cover and check if they are not blocked
mechanically
 Check the voltage on blower wires
 Check the capacitor of blower motor
