Flame-out protection：Utilizes a photocell to monitor the flame in burn chamber during normal
Electrovalve Assy ,will stop
operation.The photosensitive resistor will become infinite big , cut off
offer oil automatic.
Electrical power breakdown protection：when the power breaks down the heater stops working
without the plug being removed from the socket . When the power is recovered, the indicator will light
but the heater will not work. Please press the power switch to start up the heater.

Description of working principles：
Open the fuel cap to add kerosene/diesel in the tank. put on the fuel cap and plug the power cord in the
socket. Turn the power switch on to position "1", motor start working and the digital temperature display
light up at this time. The left display window is setting temperature and right one is room temperature. It
would ignite automatically when the setting temperature is higher than room. It begins to work, the spark
plug ignites. This heater is equipped with an electric air pump that forces air through the air line
connected to the fuel intake and then through a nozzle in the burner head. When the air passes in front
of the fuel intake it causes fuel to rise from the tank and into the burner nozzle. This fuel and air mixture
is then sprayed into the combustion chamber in a fine mist. The air blew by the fast turning fan blades
1.enters the flame steady plate and the burner, supplies additional oxygen to the burning and makes the
burning more sufficient and takes away the heat from the burner interior to outside2. enters the
heat insulation layer of A, takes away the heat from the insulation layer，so that the burner surface will
not overheats.The spark plug stops working after 12s of sparkling.
