1.- MOUNTING

Fix the burner support to the boiler. Fix the burner to the support. This allows a correct

inclination of the flame tube towards the combustion chamber. Mount the oil aspiration and

return tubes, including the oil-filter in the aspiration.

2.- OIL INSTALLATION

"Domestic" burner is equipped with a self-aspiration pump, which allows the aspiration of

combustible from the tank which is installed in a lower level than the burner, as long as the

pressure measured with a vacuometer in the pump does not exceed 30 cmHg.

3.- START UP OF THE BURNER

Make sure that there is combustible in the tank, also that the oil valves are open and there

is electric connection to the burner. Switch on the main switch. Unscrew the air-drains

screw (manometer tap). Then, when the electrovalve opens, take the photocell sensor out

of its place and approach it to a luminous source until oil comes out. Disconnect the burner

and screw the drains-screw

Observe the flame. If there is not enough combustion air, it will be dark and it will produce

smoke which will close the uptake.

On the other hand, if there is too much combustion air, the flame will be white or white-

blue coloured, reducing the efficiency and therefore not fulfilling the anti-pollution norms.

Besides, the excess of air may difficult the ignition process.

The flame must be kind of orange coloured.

Due to the construction of the boiler, if it is difficult or impossible for you to see its flame,

the combustion airflow can be set-up observing the smoke coming out from the chimney. If

it is dark, the air in the burner will have to be increased and if it is white, the air in the

burner will have to be decreased until there is no smoke at all.

If you are provided with a device, which verifies the composition of the combustion gases,

it will be the best guide to adjust the flame, but if you do not have it, follow the preceding

indications.

5.- SELECTION OF OIL NOZZLE

Go to the chart shown on page no.5 and select the correct oil nozzle in accordance with

the pressure, bearing in mind that 1 Kg/h of oil approximately produces 11.86 kW.
