Remove the bleed screw from the manifold and fit an oil
pressure gauge with R 1/8 connection to check the pump
output pressure.
Switch on the Electricity
Set the boiler burner thermostat to maximum. The boiler
burner should run on pre-purge for 7-15 seconds, with the
ignition spark energised. The solenoid valve should then
open allowing the burner to fire.
Until all the air from the oil pump is flushed out there may
be some flame instability resulting in the burner locking
out.
This will be shown by the burner stopping and the
illumination of the signal light in the reset button of the
control box (See Fig. 19). In this event, wait at least one
minute , then press the re-set button to restart.
Whilst the burner is running, vent air from the pump by
slackening the pressure gauge connection sufficient to
allow air to bleed out. When bubble free oil seeps out re-
tighten.
SEE FIG. 20
Whilst the burner is running check the oil pressure on the
pressure gauge.
If the pressure gauge is not indicating the correct reading
then adjust the pressure by turning the pressure regulator
clockwise to increase or anti-clockwise to decrease the
pressure until the pressure gauge reads:
BOILER - 8.5 bar (125Ibf/In
2
)
COOKER - 10 bar (145Ibf/In

)
