• KIT GROUND FAULT INTERRUPTER cod. 3010448
• KIT HOURCOUNTER cod. 3010450
• KIT POST-PURGING cod. 3010453
• 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 con-
sequence of depressurisation 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 var-
iations 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:
CODE 3010054 without filter
CODE 3010055 with filter
