SEE FIG. 26 OR 27
Disconnect the flexible oil pipe line at the pump inlet, open
the stop valve slowly and run off some of the oil into a
receptacle to establish an air free supply to the pump.
Remake the connection oil tight and leave valve open.
SEE FIG. 26 OR 27
Remove the bleed screw from the manifold and fit an oil
pressure gauge with R 1/8 connection to check the pump
output pressure.
Set the boiler burner time clock to continuous and turn the
boiler thermostat to maximum. The boiler burner should
run on pre-purge for 7 - 15 seconds. With the ignition
spark energised. The oil solenoid valve should open
allowing the burner on 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.
IN THIS EVENT, WAIT AT LEAST ONE
MINUTE
, then press the re-set button to restart.
SEE FIG. 26 OR 27
Whilst the burner is running, vent air from the pump by
slackening the pressure gauge port sufficient to allow air
to bleed out. When bubble free oil seeps out re-tighten.
SEE FIG. 26 OR 27
With the burner 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 until
the pressure gauge reads the correct pressure.
