Checks to ensure electrical safety should be carried out
by a competent person.
SEE FIG. 13
Remove the bleed screw from the pump 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 time clock switch 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 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. 14). In this event,
wait at least one
minute , then press the re-set button to restart.
SEE FIG. 13
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
retighten.
