TECHNICAL DATA
(1)
Reference conditions: Ambient temperature 20°C - Barometric pressure 1000 mbar - Altitude 100 m a.s.l.
(2)
Sound pressure measured in manufacturer»s combustion laboratory, with burner operating on test boiler and at maximum rated output.
ACCESSORIES
(optional):
• OUTPUT MODULATION REGULATOR KIT
Two components should be ordered:
•
output regulator to install on the burner;
•
probe to install on the boiler.
• 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
consequence of depressurization 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:

OPERATION
• On-Off (min 1 stop each 24 hours). These burners are also fiitted for the
continuous operation, if they are equipped with the control box LANDIS
type LOK 16.250 A27 (interchangeable with the burner control box LAN-
DIS LAL 1.25).
• Progressive two-stage (modulating by Kit)
