ACCESSORIES

•
LONG HEAD KIT:
Burner
• CLEAN CONTACT KIT
• KIT POST-PURGING
• KIT HOURCOUNTER
• KIT GROUND FAULT INTERRUPTER
• 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 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 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:
