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.
