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 at least 2½ litres of oil until a steady
flow of clear uncontaminated oil can be seen as
follows:
Single pipe gravity feed systems:
Disconnect the flexible oil pipe and open
the isolating valve to discharge the oil into a
suitable container.
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:
Air will be automatically vented when the boiler
is started up.
Prime the oil supply pipework to prevent
oil pump damage on single pipe systems with
a de-aerator using long oil pipe runs.
To prime a de-aerator, disconnect the flexible
oil inlet hose (nearest to the de-aerator) and
place in a container of the same fuel oil. Place
an empty container to collect oil from the oil
inlet pipe connection of the de-aerator. Prime
the de-aerator and reconnect the flexible oil
inlet hose.
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 up the boiler Control thermostat.
Allow the burner to run through to 'lock-out'
indicated by the illumination of the lockout
indicator (E).
Wait 2 minutes then press the lockout reset
indicator (E).
Repeat 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).
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 on the Danfoss BFP 11 L3 and
Suntec AS47C.
Safely dispose of the container/discharge.
