【Precautions-safety guide】page1
For your own and other’s safety please read this USER’S MANUAL and follow its
instructions carefully.
▲Danger
1、The use of gasoline is strictly prohibited, it is high volatile fuel that can cause an
explosion or uncontrolled flames.
2、Never use the heater where flammable vapors may be present, there is danger of
explosion, fire and burning。
3、Always provide adequate ventilation during the use. Only use the appliance in well
ventilated area, the air must be regular exchanged during the use (two times/one
hour），inadequate burning caused by oxygen shortage can cause carbon monoxide
poisoning。
▲Warning
1、Don’t use spay products at the location where the heater is used，the gas from the
spay tin can cause danger of fire and explosion.
2、Don’t use the appliance in place with combustible powder（wastepaper, wood crumbs,
fibre scraps），if these powder are sucked in the heater and heated up, flake and
spark may be ejected out and cause fire and burning danger.
3、Never block air inlet or heating part，it can cause abnormal burning and fire.
4、Never modify the heater, alteration may cause malfunction and fire, is very
dangerous.
5、Don’t expose the appliance to rain or snow, never use it in humidity places either.
Pull out the plug before the routine maintenance and examination.
▲Pay Attention
1、In order to prevent fire while in operation, please don’t place articles neat the
heater. Keep all combustible materials away from heater. Minimum clearances:
Outlet(front) 3M，air inlet(rear)2M，top 2M，side 2M.
2、While in operation，make sure that the ground surface does not overheat，
overheating may cause fire.
3、Do not fill fuel tank while heater is in operation, make sure the heater stops and the
flame is out. Filling while in operation may result causing fire。
4、Before use the appliance, make sure that the voltage and frequency on site is in
accordance with the ones shown on rating plate.

【Assembling wheels and tube frame】
1、insert the wheel axle to the corresponding hole of lower tube frame，set bushing G at
the two ends，slide the wheel F over the wheel axle H，put on wheel cap E。
2、Put the heater body on the lower tube frame B, make sure the 4 holes of handle
frame point towards the corresponding 4 holes on the lower tube frame respectively.
3、Insert screws J in the holes，place flat washers D under the lower frame B and tighten
the hexangular screw C。
4、Insert other screws in the holes respectively and use a screw driver to tighten them

【preparation before the operation】page5
1、Never use high volatile fuel such as gasoline etc；
2、Only fill the fuel tank when the heater stops running and the flame goes out；
3、Please use No JIS1 kerosene or frostbite-prevent light diesel，never use
degenerative, impure kerosene or diesel；
4、When you fill the fuel tank, the tank filter must be installed；
5、When kerosene or diesel touches human body please wash with soap immediately,
to prevent potential skin inflammation；
6、The burner surface is very hot just after flameout, so never touch it with hand or let
oil pump come in touch with the burner, to prevent scalding or some other injure.
◆When there is no fuel (kerosene or diesel) in the tank:
How to fill the tank：
1、Make sure the power plug is removed from the power source and the power switch is
in OFF position“0”；
2、Place the appliance on a stable and level ground, remove the fuel cap and fill the fuel
tank with fuel filter installed. Do not overfill your heater, see the full level position as
shown in under figure；
3、Check if there is water or waste in the fuel tank, clean the tank if it is dirty；
4、Fill kerosene or diesel in fuel tank with oil pump only when the fuel filter is proper
installed, after the filling turn the cap clockwise and tighten it.

◆When there is some fuel (kerosene or diesel) in the tank
Attention
1、Only check the appliance after flameout and removal of the power plug from power
source；
2、Before the ignition make sure there is no oil leakage, when oil leaks please don’t
use the appliance and contact your dealer；
3、please check the fuel tank interior, clean the tank if there is water and waste in the
tank.
【Operation】page6
Warning by ignition：
1、check the fuel tank and make sure there is enough fuel in it；
2、do not close your face near the heating part after the ignition, keep the safe
distance, min. 3 meter front from hot air outlet，top 2 meter, left and right side more
than 2 meter.（see under figure）
3、stop using the appliance when there is smoke or strange odor omitted；
4、make sure the heater is ignited before you leave it.
Safety clearances
Ignition：insert the plug in the socket，put the power switch to position“1”, the indicator
lights up, It would ignite automatically when the setting temperature is higher than
ambient temperature in LED digital temperature display.
If heater does not start, turn power switch to “0” and then to “1” position. if the heater
still does not start after three times please contact your dealer.
Attention：while the heater is operating, never let the floor ground overheats to prevent
causing fire.
◆Flameout
Pay attention 1、when you shut off the heater, make sure the flame is out before you
left the appliance.
2、Put the power switch to position“0” waitting fan stop working and
the indicator extinguishes, then remove the plug from the socket
3, DH-50 , has time-delay function , when heater off, fan will keep
running 90s to make heater cold , then stop .
◆safety device page7
Flame-out protection：Utilizes a photocell to monitor the flame in burn chamber during
normal operation.The photosensitive resistor will become infinite big , cut off
Electrovalve Assy ,will stop 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.

A．Combustion chamber B. Spark plug C. Fan blade D. Motor E. Pump
F. Air intake filter G. Air output filter H. Fuel tank I. Controller J. Air inlet pipe
K. Flame steady plate L. Oil nozzle M. Oil sucking pipe
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.
【Maintenance】
Notice 1、Before the maintenance shut off the heater and pull out the plug；
2、Never maintain the heater with fuel in tank.
◆check the fuel tank
When there is waste and water in the tank, clean and drain the fuel tank.
How to drain the fuel tank（see below figure）
1、put the heater on the working table and place an oil container under the fuel tank；
2、use a spanner to loose the drain screw und release the water and waste inside the
tank；
3、after draining tighten the drain screw again and wipe clean the left water and oil.
