When it doesn’t light even with the power
button “ON” or it gets extinguished due to
running out of oil, the FLAME Detector(Cds)
gets to work and stops the operation
Combustion safety device
If water is insucient in the boiler, it
interrupts the operation of the boiler with
the power cut o.
When water rells, the boiler starts again
automatically.
Low water level blocking device
If the temperature of the boiler rises up too
high, it is dangerous. So, in such case, this
device cuts o the power automatically.
When the overheating preventer gets to
operated the combustion stops and “CHECK”
lamp turn on.
If the overhead temperature is fall “CHECK”
lamp turn o and “RUN” lamp turning on
automatically.
If the operation stop is repeated again, contact
the sales agency or the commercial agency.
Overheating preventer
During the hard winter, the circulation pump
or the burner operates automatically to
prevent the heating circuit from freezing.
In winter, keep on plugging in the power
cord and turning the power button “ON”.
(the insulation state of the pipes must be
normal)
Freezing preventer
If the power gets o, oil gets blocked
automatically and the combustion stops.
