Fix 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 tubes, inserting the
oil filter in the intake tube.

Ensure there is fuel in the tank, that the oil valves are open and that there is an electric connection
to 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 fuel
comes out. Disconnect the burner and screw the bleed screw back in.

Adjusting the combustion conditions
As each particular installation has a different combustion circuit, it is essential to adjust the
combustion conditions of each boiler. For the

Observe the flame. If there is insufficient combustion air, it will be dark in colour and will produce
smoke, obstructing the flue outlet.
On the contrary, if there is an excess of combustion air, the flame will be pale or bluish 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, and if it is very white, 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.
