Electric shocks can be fatal!

 

– Before working on possible live components, 

ensure the unit is disconnected from the power 
supply.

 DAnGeR

Risk of injury!
Burner heads have sharp edges.

 

– Burner inspection must only be performed by 

authorized trained personnel.

 

If no issues are found when checking the burner, 
proceed to the automatic burner control unit and 
check for faults in accordance with the relevant 
operating instructions.

 ?  Fault
 ! 

 Cause
  •   Remedy

 ?  Burner does not function.
 ! 

 Valves do not open.
  •  Check the voltage supply and wiring.

 ! 

 Tightness control signals a fault.
  •  Check the valves for tightness.
  •  Note the tightness control operating instruc-

tions.

 ! 

 Control valves do not move to low-fire rate posi-

tion.

  •  Check the impulse lines.

 ! 

 Gas inlet pressure is too low.
  •  Check the filter for dirt.
  •  Check the gas supply.

 ! 

 Air inlet pressure is too low.
  •  Check the fan and air supply.

 ! 

 Gas and air pressures on the burner are too low.
  •  Check the restrictors.
  •  Check/adjust the start rate setting, see operat-

ing instructions for solenoid valve.

 ! 

 Automatic burner control unit does not function 

correctly.

  •  Check the device fuse.
  •  Note the automatic burner control unit operat-

ing instructions.

 ! 

 Automatic burner control unit signals a fault.
  •  Check the ionization cable.
  •  Check the ionization current. The ionization 

current must be at least 5 μA – stable signal.

  •  Check whether the burner is adequately 

grounded.

  •  Note the automatic burner control unit operat-

ing instructions.

 ! 

 No ignition spark is created.
  •  Check the ignition cable.

  •  Check the voltage supply and wiring.
  •  Check whether the burner is adequately 

grounded.

  •  Check the electrode – see  page 12 (7 

Maintenance).

 ! 

 Defective insulator on the electrode, ignition 

spark jumps over incorrectly.

  •  Check the electrode.

 ?  Burner performs a fault lock-out after oper-

ating faultlessly in normal operation.

 ! 

 Incorrect gas and air flow rate settings.
  •  Check the differential pressures for gas and air.

 ! 

 Automatic burner control unit signals a fault.
  •  Check the ionization cable.
  •  Check the ionization current. The ionization 

current must be at least 5 μA – stable signal.

 ! 

 Burner head is dirty.
  •  Clean gas and air bore holes and air slots.
  •   Remove  deposits.

 ! 

 Excessive pressure fluctuations in the combus-

tion chamber.

  •  Ask Honeywell Kromschröder for control 

concepts.
