Starting the appliance

NOTICE:
▶ Never run the appliance when the appliance/system
is unpressurised (sealed systems) or empty.
Check the oil supply is correctly fitted and in good working order before
turning on the oil supply valves to the boiler.
▶ Turn on the main oil supply valve at the tank and draw off oil until a
steady flow of clear uncontaminated oil can be seen as follows:
– The oil supply to the boiler should be primed before the burner is
operated to avoid unnecessary pump wear.
– The use of an oil suction pump will prime and flush through any oil
supply set up simply and easily.
Alternatively the following procedure can be used -
Single pipe gravity feed systems:
▶ Disconnect the flexible oil pipe and open the isolating valve to
discharge the oil into a suitable container.
▶ If a top entry tank has been used the pipework will need to be primed
before the oil will discharge under gravity.
▶ When completed, close the isolating valve, reconnect the flexible oil
pipe.
Double pipe sub-gravity feed system and single pipe suction lift with
de-aerator:
▶ Prime the oil supply pipework to prevent oil pump damage.
▶ To prime a de-aerator, disconnect the flexible oil inlet hose (F) from
the isolation valve and place in a container of kerosene (G).
Connect a spare flexible oil hose (E), to discharge into container (G).
Open the isolating valve, turn on the power to the boiler and set the
programmer to ON. Prime the de-aerator until there is a steady flow
of oil into container (G). Turn off the boiler then reconnect the
flexible oil inlet hose (F).
▶ Turn on the boiler, the oil level in the de-aerator will drop as the oil is
used until the oil is drawn from the tank. If the de-aerator empties and
the burner locks out before the oil is drawn from the tank prime the
de-aerator again.
▶ Open the isolating valve and the oil pump bleed valve (A) to discharge
into a suitable container once the boiler is started up.

▶ Switch on the electricity supply to the boiler.
▶ Set the programmer to ON.
▶ Turn on the boiler control thermostat.
▶ Allow the burner to run through to 'lock-out' indicated by the
illumination of the lockout indicator (H), (note: some systems will not
▶ lock out).
▶ If lockout occurs wait 2 minutes then press the lockout reset button
(J).

▶ Repeat the procedure at least 3 times or until a steady stream of oil,
without air, runs from the bleed port, then lock the bleed port.
▶ Switch off the boiler.
▶ Remove the oil pump filter, clean with kerosene and refit.
The internal filter is accessed by removing the oil pump cover.
▶ Safely dispose of the container/discharge.
▶ Fit a suitable pressure gauge to port (A) on the oil pump.
▶ Adjust the air shutter (L) and pump pressure (B) as shown in the
table 4 on page 36. The burner should ignite following a pre-ignition
period of approximately 15 seconds.
▶ If changing the burner output, check the position of the air damper
disc is correct to the output as shown in the table below.
