This thermostat is a safety cut-out device which will
operate under adverse wind or a blocked flue condition.
It is a manually reset device which can be reset by
pressing in the centre.
SEE FIG. 23
Remove the bleed screw from the manifold and fit an oil
pressure gauge with R1/8 connection to check the pump
output pressure.
Switch on the Electricity
Set the cooker oven timer to manual, turn the thermostat
to maximum. The burner should run on pre-purge for 7 to
15 seconds, with the ignition spark energised. The oil
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. 24). In this event,
wait at least one
minute , then press the re-set button to restart.
SEE FIG. 23
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.
SEE FIG. 23
After 15 minutes
Whilst the burner is running check the oil pressure on the
pressure gauge. Wait for 30 seconds after ignition, for the
burner to establish full firing rate.
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 7.6 bar (110
lb/in
2 ).
Switch off the burner, remove the pressure gauge and
refit the bleed screw.
