Troubleshooting
Whenever a fault occurs, check to ensure
that the system is functioning according to
basic specifications:
1.
Is it connected to the power
supply ?
2.
Is there oil in the tank ?
3.
Are all shutoff valves open ?
4.
Are all regulating and safety
devices (boiler thermostat, low
water level detector, end-limit
switches, etc.) correctly adjusted ?
If the fault cannot be rectified after
checking the above points, inspect
each burner component in turn to check
that it is functioning as part of the
system.

automatic firing unit, and check their
meaning with the following table..

optional accessory) to obtain further
in-depth information on the system’s
operating and malfunction procedures.

components. Replace them with original
parts bearing the same order number.
