STARTING THE APPLIANCE
IMPORTANT: Never run the appliance when
the appliance/system is unpressurised
(sealed systems) or empty.
14Check the oil supply is correctly fitted and
in good working order before turning on
the oil supply valves to the boiler.
4Turn on the main oil supply valve at the tank
and draw off at least 2
1
/
2
litres of 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.
4Single pipe gravity feed systems:
4Disconnect the flexible oil pipe and open
the isolating valve to discharge the oil into a
suit
able container.
4If a top entry tank has been used the
pipework will need to be primed before the
oil will disc
harge under gravity.
4When completed, close the isolating valve,
reconnect the flexible oil pipe.
4Double pipe sub-gravity feed systems
and single pipe suction lift with de-aerator:
4To prime a de-aerator, disconnect the
flexible oil inlet hose (E) from the isolation valve
and place in a container of kerosene (F).
Connect a spare flexible oil hose (G), to
discharge into container (F). 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
cont
ainer (
F). Turn off the boiler then
reconnect the flexible oil inlet hose (E).
4Turn 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
.
4Open the isolating valve and the oil pump
bleed valve (A) to discharge into a suitable
container once the boiler is started up.
4Switch on the electricity supply to the boiler.
4Set the programmer to ON for CH and DHW.
4T
urn on the boiler CH control thermostat.
4Allow the burner to run through to 'loc
k-out'
indicated by the illumination of the lockout
indicator on the lockout reset button (H).
4Wait 2 minutes then press the lockout reset
button (H).
4Repeat the procedure at least 3 times or
until a steady stream of oil, without air, runs
from the bleed port, then relock bleed port (A).
4Switc
h off the boiler
.
4Remove the oil pump filter, clean with
kerosene and refit.
T
he internal filter is accessed by removing
the oil pump cover
.
4S
afely dispose of the cont
ainer/discharge.
