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).

(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. The
sound power is measured with the “Free Field” method, as per EN 15036, and according to an “Accuracy: Category 3” measuring accuracy,
as set out in EN ISO 3746.
OUTPUT MODULATION REGULATOR KIT
Two components should be ordered:
•
output regulator to install on the burner;
•
probe to install on the boiler.
