DANGER
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is discon-
nected from the power supply.
Risk of injury! Burner heads have sharp edges.
Fault-clearance must only be undertaken by author-
ized trained personnel.
▷
If no fault is detected when checking the burner,
proceed to the automatic burner control unit and
check for faults in accordance with the relevant
operating instructions.
? Faults
! 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 instructions.
! Control valves do not move to low-fire position.
• Check the impulse lines.
! Gas inlet pressure is too low.
• Check the filter for dirt.
! Gas and air pressures on the burner are too low.
• Check the restrictors.
! Automatic burner control unit signals a fault.
• Check the ionization cables and ionization cur-
rent.
• Check whether the burner is adequately
grounded.
• Note the automatic burner control unit operating
instructions.
? Burner performs a fault lock-out after burn-
ing faultlessly in normal operation?
! Incorrect gas and air flow rate settings.
• Check the gas and air pressures.
! No ignition spark is created.
• Check the ignition cable.
• Check the voltage supply and wiring.
• Check whether the burner is adequately
grounded.
• Check the electrodes – see page 10 (Checking
the ignition and ionization electrodes).
! Automatic burner control unit signals a fault.
• Check the ionization cable.
• Measure the ionization current by connecting a
micro-ammeter into the ionization cable: min.
5 µA ionization current – stable signal.
