• 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
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 depressurisation or air leaking past imper-
fect 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:
Code
20034277 without filter
Code 20034281 with filter
For burner deliveries higher than 80 kg/h, install two parallel de-
gassing units.
• Kit for lengthening the combustion head
L = Standard length
L1 = Length obtainable with the kit
• Spacer for shortening the combustion head
L = Spacer thickness
L1 = Resulting length of combustion head
• Soundproofing
The sound attenuating shroud significantly reduces the noise
generated by the burner (- 10 dBA).
The casing is in steel and sound-damping material and fully en-
closes the burner.
The casing is wheel-mounted so that it can be easily removed for
burner inspection.
