DANGER
Risk of explosion and poisoning in case of
burner adjustment with an air deficiency! Ad-
just the gas and air supply so that the burner is
always operated with excess air – otherwise CO
will form in the furnace chamber. CO is odourless
and poisonous! Conduct a flue gas analysis.
Produce a maintenance report.

Assistance in the event of
malfunction
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.
! 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 operating
instructions for solenoid valve.
! Automatic burner control unit does not function
correctly.
• Check the device fuse.
• Note the automatic burner control unit operating
instructions.
! Short-circuit of the UV sensor.
• Replace the UV sensor.
• Note the UV sensor operating instructions.
! Automatic burner control unit signals a fault.
• Check the ionization cable.
• Check the ionization current. The ionization cur-
rent must be at least 5 µA – stable signal.
• Check whether the burner is adequately ground-
ed.
• Note the automatic burner control unit operating
instructions.
! No ignition spark is created.
• Check the ignition cable.
