Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler and at maximum rated output. The
sound power is measured with the “Free Field” method, as per EN 15036, and according to an “Accuracy: Category 3” measuring accuracy,
as set out in EN ISO 3746.

• RADIO DISTURBANCEPROTECTION KIT
If the burner is installed in places particularly subject to rad
io disturbance (emission of signals exceeding 10 V/m)
owing to the presence of an INVERTER, or in applications where the length of the thermostat connections exceeds
20 metres, a protection kit is available as an interface between the control box and the burner.

• DEGASSING UNIT
It may occur that a certain amount of air is contained in the ligh
t oil sucked up by the pump. This air may originate from the light oil itself as a con-
sequence of depressurisation or air
leaking past imperfect seals.
In double-pipe systems, the air returns to the tank from the retur
n pipe; in single-pipe systems, the air remains in circulation causing pressure var-
iations in the pump and burner malfunctions.
For this reason, we advise inst
alling a degassing unit near the burner in single-pipe installations. Degassing units are provided in two versions:
CODE 3
010054 without filter
CODE 3
010055 with filter
Degassing unit characteristics
• Burner output : 80 kg/h max
• Light oil pressure : 0.7 bar max
• Ambient temperature : 40 °C max
• Light oil temperature : 40 °C max
• Attachment connectors : 1/4 inch
