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.
Two components should be ordered:
• the output regulator to install on the burner
• the probe to install on the heat generator
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.
EXTENDED HEAD KIT
“Standard head” burners can be transformed into “extended
head” versions, by using the special kit. The kits available for the
various burners, giving the original and the extended lengths, are
listed below.
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:
SPACER KIT
If burner head penetration into the combustion chamber needs
reducing, varying thickness spacers are available, as given in the
following table.
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.
SOUND PROOFING BOX
If noise emission needs reducing even further, sound-proofing
boxes is available.
