Before using the boiler
5
Use of the oil, other than the one specied on the
name plate on the front of the boiler, may result
in a re or explosion.
Be sure to check the fuel prior to use.
The power supply, if higher or lower than the
one specied son the front of the boiler,
may cause a re.
Be sure to check the power supply.
Highly inammable materials, such as volatile
oil or alcohol, may cause a re during ignition of boiler.
Use of boiler for drying cloths may result in a re.
Never place any inflammable and
combustibleobjects near boiler.
If the chimney pipe (chimney) is incorrectly connected
with the boiler, exhaust gas may ow into the indoors
during operation, which may cause a carbon oxide
poisoning.
Check if the chimney pipe (chimney)
is incorrectly connected or pulled out.
WARNING

The fuel shall be kept in a place without direct
sunlight, free from the impact of oil, re, rain,
or dust.
Any foreign object in the oil tank may cause the
deteriorated combustion, boiler malfunction,
or the shortened life of th boiler.
Be sure to close the oil tank lid.
Check if water is in the makeup water tank.
When the water is insucient to operate the boiler,
the makeup water lamp (red) on the controller
will light.
Check if there is any water leak in the heating and
the hot water pipes of the boiler.
CAUTION

Notes when using
7
Adjustment of the damper on the burner at will may
cause a re due to incomplete combustion.
Do not adjust the damper (air controller)
on the burner at will.
Incomplete combustion due to oxygen deciency
may lead to a carbon oxide poisoning.
Do not stop up the air intake and the
vent to prevent a draft in the winter.
Exhaust gas, if owing into the indoors, may cause
a carbon oxide poisoning.
Close all the boiler room doors leading
to the indoors before use.
Adjustment of the damper on the burner at will may
cause a re due to incomplete combustion.
Do not adjust the pressure of the gear
pump at will.
WARNING

8
Use of the boiler for drying clothes may result in a re.
Use of the boiler for cooking may result in a personal
injury.
Use the boiler only for heating and
supplying hot water.
Hot temperature on the chimney pipe (chimney)
or nearby the vent may result in a burn.
When the boiler is operating or right
after the boiler is turned off, do not touch
the portions near the vent or the chimney
pipe (chimney).
Operation of the boiler, with oil leak or stagnant oil,
may cause a re.
Check if there is any oil leak on the oil tank,
the oil pipe, and the boiler (inside/outside).
Several power plugs inserted into one power outlet
may cause a re.
Do not insert several power plugs into
one power outlet.
CAUTION

9
Random use of a non-rated
fuse may cause a fire.
Replace the fuse, if burnt out, with the one
complying with the specifications.
(Refer to the Electric wiring diagram)
Failure to detect the level (water) inside the boiler may
result in malfunction of the boiler.
Do not make a short circuit between the low
water level sensor wire and the ground wire
inside the panel.
An electric shock may be caused.
Do not touch the power cord with wet hands.
Random disposal may result in a safety accident,
especially to children or the old and the weak.
Disposal and replacement of the boiler,
if necessary, shall be performed by the
installation personnel.
CAUTION

10
Please receive A/S regular inspection at least once a
year from the dealer where you purchased the unit
for safe and lengthened use of your boiler.
Please submit a request for inspection of
your unit at least once a year.
Failure of the anti frost function may result in
implosion of the boiler and its pipeline.
Never shut off the power supply, nor set
the power switch at the off position in
the winter.
The boiler shall keep operating not to get frozen
or burst during the winter. If the distributor valve
or the oil middle valve is closed, the boiler stops
operation, which may cause the boiler and
pipeline implosion.
Open the distributor valve and the oil
middle valve when you go outside in
the winter.
With any abnormality in the boiler, the checkup lamp
on the controller will light, and the check lamp on the
room temperature controller will be blinking.
Then, press the restart button 2 to 3 times for reoperation.
If any abnormality still exists consult with a selling agency
where near your town, or where you purchased from.
Consultation with the installation personnel

Boiler LST-58K

12
Burner KPO-50B-Navien LST-58K
ූFlame detector : to detect the ame of the burner for safe burner operation.
ූGear pump : This device sucks and pressurizes oil for combustion.
ූAir damper : to adjust the air volume for the fan.
ූIgnition transformer : to generate high voltage to ignite the fuel
ූElectrode : to ignite the fuel with the high voltage from the ignition transformer.
Do not touch the electrode when the power is on, as electricity is
owing through the electrode. ( Warning)
ූFan motor : to circulate the fan to supply air for combustion.
ූNozzle : to spray the fuel to be ignited.

Sfety Device
13
1. Safety device for power failure
This device automatically shuts o the oil to stop operation during power failure.
2. Safety device for power recovery
When the boiler recovers from power failure, this device helps the boiler to automatically
re-start for normal operation (which functions for 2 hours).
3. Non-ignition protection device (Flame detection)
ූThis device automatically shuts o the oil supply when the boiler does not ignite.
ූThis device also shuts o the oil supply automatically, when the ame goes out during
normal combustion.
4. Quasi ame protection device
This device stops boiler operation, when there is any ame remaining inside the boiler
prior to normal operation.
5. Anti overheat device (for prevention of hot temperature)
This device shuts o the oil supply for stopping the boiler operation automatically,
when the heat exchange is overheated.
6. Low water level shut o device
This device indicates that the boiler has run out of water and stops the boiler operation.
7. Temperature controller protection device
This device stops the boiler operation, if there is any abnormality in the temperature sensor.
8. Anti frost device
This device automatically circulates water and raises the water temperature in order to keep
the boiler from getting frozen with the anti frost function, when you go outside in the winter.
9. Short circuit protection device
This devices stops boiler operation by cutting o the fuse, when there is any abnormality
in the wires (short circuit) inside the boiler or when the over current is generated to exceed
the rated capacity of the fuse.
10.Lightening and static electricity protection device
The protection device to prevent a lighting strike (lightening) and the
electrostatic discharge is supplied in the controller.
