BURNING SYSTEM
(1) When the Power Switch is pressed, the Igniter is electrically generated to preheat
the Burner Bottom. The completion time of preheating is detected by electric timer,
of which standard time is approximately 90 sec. at a room temperature of 15 °C,
provided that it is approximately 180 sec. if the room temperature is lower than 6 °C.
In the case of the shortest time (for instance, when re-igniting shortly after
extinguishing burning), a shorter time of approximately 40 sec. is obtainable.
(2) Upon the completion of preheating, the combustion air is sent into the Burner, while
the fuel is sent from the Fuel Nozzle, at the same time. The fuel is instantaneously
evaporated and immediately ignited with the Igniter which has been red-heated at a
temperature of higher than 900 °C.
(3) After ignition, “Med-High” burning continues for approximately 40 sec., to raise the
temperature of the Burner, after which burning is automatically controlled for the
burning sequence of “High ↔ Med-High ↔ Med. ↔ Med.-Low ↔ Low. The Igniter
becomes off while the heater is in burning operation. The Burner bottom maintains a
high temperature burning of higher than 300 °C by receiving a high radiation heat
from the Burner Ring.
(4) When the Power Switch is pressed again, the burning will cease in around 5 sec.
The Circulation Fan will run for approximately 90 sec. and then stop automatically.
