1. OVERALL VIEW
These instructions are suitable for KRH Series hybrid Wood fired boiler;
Do not forget this instruction.
To ensure the correct installation, commissioning and servicing of domestic central heating system.
NEW CONCEPT & NEW TECHNOLOGY
1. Exhaust / intake phase modulation system
As ventilation quantity is modulated by MCU that checks the rising speed of water temperature in real time, the
optimum combustion condition and long heating are realized.
2. The advanced exhaust / intake system
The exhaust/intake system is applied to wood fired boiler for the first time in the country so as to prevent backfire in the
combustion chamber during combustion. Thus, the internal pressure of combustion chamber becomes negative(minus)
and fan operates only when necessary, i.e., turbo system that increases heat power in the shortest time is applied.
3. The first domestic oil igniting system
After supplying firewood, there is no need to take pains to ignite it, but firewood can be easily ignited only with igniting
button.
4. special hot water coil heat exchange system of high efficiency
As hot water heat exchanger is placed at the highest positon (highest temperature part), boiling in the internal box of
boiler is prevented and abundant hot water can be used. Since hot water of heat exchanger flows up and down in
double structure, heat exchange rate is increased to supply sufficient water for bath.
5. hybrid systems of firedwood and oil
As firewood combustion is detected by internal sensor, oil burner automatically operates when combustion stops so as
to supply heat for heating.
6. Heat exchange system of high efficiency
As water tube grate and upper fire tube are installed inside, combustion gas is emitted after heat is fully exchanged inside
heat exchanger.

* In using a flue, Check the status of flue every 6 months, * Install the flue 3m above the boiler along with
replace it when there is much soot in it. a “T” unit at the end of the flue in order to
prevent incomplete combustion caused by
damaging winds.
▶ Cautions in installing Flue
▶ Install the flue in such a way that the flue is free from the wind pressure zone, rain or wind
Warning: Installation of additional flue
1. Clearance greater than 30 cm should be ensured from the flue to
prevent contact with combustible materials, and the flue should be
finished with incombustible materials
2. Sudden heat may be emitted by the flue when supplying sthe fuel.
Do not store inflammable or combustible materials in the vicinity of
the stove pipe. Install the flue, taking care to ensure sufficient clearance
from the flue.

3. INSTALLATION
▶ 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.
The provision for satisfactory flue termination must be installed in accordance with local regulations.
The appliance must be installed so that the flue terminal is exposed to outdoor air.
The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the
position of the terminal allows a free passage of air across it at all times. The terminal should be located with due
regard for the damage or discoloration that might occur on buildings in the vicinity,
it must also be located in a place not likely to cause nuisance. In cold or humidity weather water vapor may condense
on leaving the flue terminal The effect of such “steaming” must be considered. If the terminal is less than 1 meter
above a balcony, above ground or above a flat roof to which people has access, then a suitable stainless steel terminal
guard must be fitted. The minimum acceptable spacing from the terminal to obstructions and ventilation openings
are specified in Fig. X.
* Warning
The exhaust gas duct must not be contact with or close to inflammable material and must not pass through building
structures or walls made of inflammable material. When replacing an old appliance, the flue system must be changed.

1. Before switching-on, please check the followings after finishing the installation of boiler, flue, pipes, and electricity.
① 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.
② Do not place combustible or inflammable materials in the vicinity of the boiler.
Install 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 clean.
③ Never disassemble, repair or modify without approval of the manufacturer.
Shock or fire may result.
Contact the after-sales service center when the boiler needs repairing.
④ Never touch the stovepipe while you operate boiler.
You may get burnt.
⑤ 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)
- If 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.
⑥ 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

Precautions
1. 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.
2. 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.
3. After adding firewood, tightly close the inlet.
The sparks may cause a fire in the surrounding area.
4. When opening/closing the wood hatch, be careful to not burn yourself.
When opening the wood hatch, open the door in a lateral direction in order to avoid possible heat burns.
5. Use the firewood considering the function of the wood.
If the mode is set for oil, the use of firewood is strictly prohibited.
If any accident occurs in violation of this warning, the company will not be responsible for any situation that occurs.
6. Install the boiler in a structure where cleaning is easy.
The use of wet wood requires frequent cleaning due to resin; use dry firewood if possible.
If you use wet wood, you should clean the boiler every 3-4 days.
