▶ Turn on the boiler, set the programmer to ON and turn the room
thermostat up to create a demand for heat.
The oil level in the de-aerator will drop whilst the oil is being drawn
from the tank. If the de-aerator empties and the burner locks out
before the oil is drawn from the tank, you will have to prime the de-
aerator again.

6.4.4 Burner head setting
Adjustments to the burner head are made on the basis of the required
output, refer to table 9 for the required setting for your boiler.
Fig. 51 Burner head adjustment thumbwheel
One complete rotation clockwise (cw) from the minimum position
equals approximately one millimetre. Adjust the thumb-wheel to achieve
the setting indicated in the table 9, according to your appliance model
and output.
Using an engineer’s rule or vernier gauge measure from the lip of the
blast tube to the inside of the break plate as show in the figure below.
Ensure that the break plate is level, check at four equal points to get an
average of the required setting. The setting tolerance should be no more
than ± 0.25mm
Adjust position of air damper discs to suit burner output
(see table 9 on page 32), located as above. Access by
undoing the two screws [4] to release the air inlet cover.
