WARNING:
If continued unsuccessful ignition attempts
are made it is possible to accumulate a
significant quantity of oil and oil mist in the
combustion chamber which, if the burner then fires, can
result in a dangerous situation. Any such accumulation
of oil must be removed by safe means before any further
attempt to light the burner.
1. Ensure the oil gauge is connected. Remove the sample
point cover plug from the outlet flue length and insert a
CO2 measuring instrument.
2. Turn ON the main electricity supply and check that the
following sequence of events occur. i) Burner fan runs. ii)
Ignition spark is heard. iii) Main flame is established.
