2) Ignition Through Using the Wood
3) Insert wood in a good size enough to close the wood hatch completely.
Ex) The burning time may be differ with the kind of wood and, in general, 20kg of firewood may
be burnt for 4-5 hours.
Stack completely dried wood (thin wood) in the firebox in a zigzag pattern and light the firewood
using paper or cardboard box scraps.
-> Continuous combustion is possible through adding more firewood as soon as wood is lit
<When inserting the firewood>.
Insert wood in a good size enough to close the wood hatch completely
Put the "Tinder" in the central part of the firebox, add the firewood, and light the Beongaetan
using papers, etc. Keep the ashtray hole open until the firewood is ignited to a certain level.

Precautions
Precautions
The boiler shall be inspected once a year.
Request your distributor to conduct periodic inspections of the boiler
(i.e., once or twice a year).
You can operate the boiler safely only when the boiler has been properly inspected.
Prevent frozen rupture during winter season.
If the product is connected to the pipes, and the pipes are fully filled with water,
connect the power cable to the outlet. If there is insufficient water in the pipes, then
supply water to the pipes in accordance with the water makeup method. Operating
the rupture prevention circuit when the pipes are filled with insufficient water may
cause the pump to run idle or cause overheating or failure of the pump.
Fully insulate the pipes.
Take the appropriate actions to prevent a frozen rupture by, for example, winding
heating coils around the exposed pipes in the cold area.
(It is also desirable to install the pipes adjacent to the heating pipes for insulation.)
Do not wrap the water drain valve with an insulator.
When you do not use the boiler for an extended period, drain the water from the
boiler to prevent a frozen rupture, and disconnect the power cable from the outlet.
The exposed pipes should be wrapped with an insulator 25mm thick or more to
prevent the pipes from freezing (50 mm or more in cold areas)
f you leave your home for a number of hours, open the hot water tap in the kitchen
slightly to allow a small volume of water to flow into the hot water pipe to prevent a
frozen rupture of the tap water pipe.
Use the power outlet exclusive for the boiler, and be cautious for leakage.
The operating power is AC 230 and 50 Hz. Operate the boiler only after checking
the voltage.
Do not touch the power cable or operate the boiler with wet hands to avoid
electric shock. Never clean the boiler with water as a leak, shock or failure of
the boiler may result.
Do not place combustible or inflammable materials in the vicinity of the boiler.
Put a fire extinguisher in the boiler room
Do not stack wooden materials or place inflammable or combustible materials
in the vicinity of the boiler, and keep the area surrounding the boiler clea
Never touch the stovepipe while you operate boiler.
You may get burnt.

firewood if possible.
If you use wet wood, you should clean the boiler every 3-4 days.
In a power failure, be careful about overheating.
If electric power is not supplied, the blower and circulation pump do
not work and the risk of overheating and fire is increased.
Do not add an excessive quantity of fuel at anytime.
If an excessive large quantity of fuel is added, the hot water or steam
can burn you, as overheating is likely to occur.
When opening/closing the wood hatch, be careful to not burn your self.
When opening the wood hatch, open the door in a lateral direction in
order to avoid possible heat burns.
After adding firewood, tightly close the inlet.
The sparks may cause a fire in the surroundings area.
As sparks may be dispersed resulting in a fire during the time to treat
the ash, clean the product after the complete removal of embers.
Cautions in using wood fuel
Use the designated fuel only.
Firewood can only be used in this boiler. Use of other fuel (brown coals,
briquettes, or household waste may reduce the lifetime of the product
and should be prohibited.

How to install
Installation of flue
▶Install the flue 3m above the boiler
along with a T unit at the end of
the flue in order to prevent
incomplete combustion caused by
damaging winds.
Cautions for Installation
Install the flue in such a way that the flue is free from the
wind pressure zone, rain or wind.
If there is a tall building or an obstacle within 1 m of the
flue, install the flue 1 meter higher than the roof of the
building.
Install the flue at a location 3 meters or higher than the
top of the boiler
The height of the installed flue should be greater than
three times the horizontal length.
If the flue is installed in a wind pressure zone, excessive soot
resulting from incomplete combustion may result, thus
reducing operational efficiency, safety shutdown may be
triggered, causing abnormal operation of the boiler To
prevent this, the flue should be installed in a position outside
the wind pressure zone.
Especially, when you use wood or coal fuel, you should
avoid the wind pressure band.
