OUTPUT POWER REGULATOR KIT RWF 40
With the modulating operation, the burner continually adapts the
power to the request for heat, ensuring great stability for the pa-
rameter controlled: temperature or pressure.

POTENTIOMETER KIT
Depending on the servomotor fi tted to the burner, a three-pole
potentiometer (1000 ) can be installed to check the position of
the servomotor.

DEGASSING UNIT
It may occur that a certain amount of air is contained in the fuel
sucked up by the pump.
This air may originate from the fuel itself as a consequence of de-
pressurisation 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:

HEAD KIT FOR REVERSE FLAME CHAMBER
In certain cases, the use of the burner on reverse flame boilers
can be improved by using an additional cylinder.
