STARTING THE APPLIANCE
IMPORTANT: Never run the appliance when
the appliance/system is unpressurised
(sealed systems) or empty.
1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 procedures 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 systems
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 electrical supply to the boiler.
Switch on the boiler at the power switch.
IMPORTANT: The burner has an 11 second
delay before the motor is activated.
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 ( I ).
Repeat the procedure at least 3 times or
until a steady stream of oil, without air, runs
from the bleed port, then relock the bleed port.
Switch off the boiler at the power switch.
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.
