IGNITION AND REGULATION WITH COMBUSTI-
BLE OIL
1) Check that the nozzle characteristics (output and
spray angle) are suitable for the combustion chamber
(see BT 9351/1). Otherwise, replace the nozzle, fitting one of
the right type.
2) Check that there is fuel in the main tank and that fuel is suitable
for the burner, to judge by its appearance at least.
3) Check there is water in the boiler and that the plant gates are
open.
4) Make absolutely sure that discharge of combustion waste
cannot occur without hindrance (boiler gates and chimney
open).
5) Check that the operating voltage of the electric line corresponds
to what the burner requires and that electrical connections of
the motors and resistances are correct for the available voltage

nufacturer. Check that the combustion head is in the position
considered suitable for supplying the desired quantity of fuel
(for relatively low fuel supply the air passage between disk
and head must be considerably reduced; for fairly high nozzle
output the passage between disk and head must be relatively
open) - see the chapter "Combustion head regulation".
