Secure the burner support to the boiler. then fix the burner to the support. This will allow the
correct tilt of the flame tube towards the combustion chamber. Fit the intake and return pipes.

First place a manometer and a vacuum gauge and prepare the combustion analyser.
The "Domestic" burner is equipped with a self-priming pump, which allows the aspiration of fuel
from a tank installed at a lower level than the burner, as long as the vacuum measured with the
vacuum gauge in the pump does not exceed 0,4 bat (30cmHg).
The suction of fuel must never reach the bottom of the tank, always leaving a minimum distance of
10 cm to the bottom, if possible, the suction kit with float is recommended.
In installations that allow it, the fuel returns must be made to a recirculation filter with air purge,
thus avoiding oxidations in the diesel pump.
Make sure there is fuel in the tank, that the oil valves are open and that voltage is reaching the
burner. Turn on the master switch. Unscrew the air bleed screw (manometer point). Then, when the
valve opens, remove the photocell sensor and move it towards a light source until the oil comes
out. Disconnect the burner and screw the bleed screw back in.

As each particular installation has a different combustion circuit, it is essential to adjust the
combustion conditions of each boiler. In order for the guarantee to be valid

Observe the flame. If there is insufficient combustion air, it will be dark in colour and will produce
smoke, rapidly obstructing the flue outlet.
On the contrary, if there is an excess of combustion air, the flame will be whitish or bluish-white in
colour. This will reduce the performance of the boiler and it will fail to comply with anti-pollution
standards, and the excess air may also hinder the ignition process.
The flame should be orange in colour.
If the shape of the boiler makes it difficult or impossible to observe the flame, the combustion air
flow can be regulated by observing the smoke coming out of the flue. If the smoke is dark in colour,
more air will need to be provided to the burner, or if it is a very whitish colour, the air in the burner
will need to be decreased until no smoke at all is observed.
If you have a device for determining the composition of the combustion gases, this will be the best
guide for flame adjustment. If not, simply follow the above indications.
To adjust the air and burner line conditions, carefully follow the instructions given below.
