Troubleshooting
Fault diagnosis and repair
In the event of a malfunction, first check
that the prerequisites for correct
operation are fulfilled:
1.
Is the system connected to the
power supply?
2.
Is there oil in the tank?
3.
Are all shut-off valves open?
4.
Are all control and safety devices,
such as the boiler thermostat, low-
water detector, limit switch, etc.
adjusted correctly?
If the cause of the malfunction cannot be
ruled out by the checks described
above, check the functions associated
with individual burner parts.

Safety components must not be
repaired. They must always be replaced
with parts with the same order number.
Only use original spare parts.
Disconnect the electrical supply
before carrying out any
maintenance or cleaning work.
After any work in the system, check
combustion under normal operating
conditions (doors closed, cover
fitted, etc.). Enter the measurement
values in the boiler room
documentation.
