RADIO DISTURBANCEPROTECTION KIT
If the burner is installed in places particularly subject to
radio 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 light
oil sucked up by the pump. This air may originate from the light
oil itself as a consequence of depressurization or air leaking past
imperfect seals.
In double-pipe systems, the air returns to the tank from the return
pipe; in single-pipe systems, the air remains in circulation causing
pressure variations in the pump and burner malfunctions.
For this reason, we advise installing a degassing unit near the
burner in single-pipe installations.
Degassing units are provided in two versions:
