Clean contacts kit
A clean contacts kit is available for installation on the burner. It
can be used as a remote interface between the operating signals
of the burner. Each burner can be fitted with a single kit for de-
tecting the flame presence signal and indicating a burner lockout.

Radio disturbance protection kit
If the burner is installed in places particularly subject to radio dis-
turbance (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 kit
It is possible that there is air in the fuel sucked up by the pump
coming from the fuel itself that has been subjected to depression
or else a seal is not completely watertight.
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:
