STARTING THE APPLIANCE

IMPORTANT: Never run the appliance when the appliance/system is unpressurised (sealed systems) or empty.

1Check 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 21/2 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.

Single pipe gravity feed systems:

Disconnect the flexible oil hose 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 hose.

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 (H), 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 for CH and DHW.

Turn on the boiler CH control thermostat.

Allow the burner to run through to lockout indicated by the illumination of the lockout indicator (E).

Wait 2 minutes then press the lockout reset button (D).

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 (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, Suntec AS47C and Riello RDB.

Safely dispose of the container/discharge.
