Correcting a burner fault
NOTICE: System damage due to frost.
When there are freezing conditions, the heating system
can freeze if it is not operational, e.g. because of a fault
shutdown.
▶ When there is a risk of frost, protect your heating
system against freezing.
▶ If your heating system has been shut down for several
days due to a fault shutdown and there is a risk of
frost, drain the heating water at the drain & fill valve.
Also leave the air vent valve at the highest point in the
system open.
NOTICE: System damage from pressing the reset button
too frequently.
This can damage the burner ignition transformer.
▶ Press the reset button no more than three times in a
row.
The display shows heating system faults. Further information on the
fault displays can be found in the service instructions of the relevant
control unit. In addition, burner faults are signalled by an indicator on the
burner.
▶ Press burner reset button (see burner operating instructions).
If the burner still fails to start after three attempts, contact a contractor.
