Before using the boiler

Checking points before starting up

It is essential to use only kerosen or light oil. (Don’t use gasoline, alcohol) It is better to use kerosene when the temperature goes down below -5ఁ In winter, don’t use the light-oil for summer.

Store in the Place where there is no eect of oil, re, rain, and keep out of the sun. Pay attention that water or dust may not get in on time of feeding oil. (Water or dust may cause the combustion failure or shorten the boiler span.) Wipe o the oil spilled. Close the lid of the oil inlet without fail.

Feed oil after turning the power o and locking the tank valve.

Check out if or not oil leaks in the connecting part of the oil pipe.

Fuel

Check out that there is enough water in the body of the boiler without failure. Expansion tank type-Check out if there is water in the Expansion tank, and in case that there is no water, please ll water in the body of the boiler. Open Expansion Tank type-check out if there is water in the expansion tank, and in case that there is on water, press the power button. Then, ‘Low Water Level’ lamp turns on and water is supplied automatically.

Notes when using

Put the surroundings of the boiler in order and don’t put the ammables near the boiler.

Check out whether the ignition and the combustion is normal.(Checking through the ame inspection window.) When the boiler is going to be not in use for a long time, cut o the power.(Don’t pull out the power cord when there is a danger of freezing.) If you pull out the power plug on time of thunder and lightening, you can prevent the damage on the boiler by the falling of the thunderbolts.

Be careful not to get burned due to the high temperature of the exhaust/inhale pipe (exhaust pipe). In case of emergency such as you may feel the abnormality of the boiler, cut o the power. Don’t use the hot water for food.

How to use

How to exhaust

Be careful that the oil tank may not run out of oil completely. In that case, even though oil is supplied, air may get in. As a result, ignition failure or operation failure may occurs.

Untighten the screw for exhaust in the oil lter by a screwdriver, the air goes out. When oil ows out, please tighten it. (This is possible only in case that the oil tank is above the oil lter.)

If the oil tank is below the oil lter or the air ows out enough like the above, lock the screw for exhaust and remove the air with the exhaust valve.

In such case, open the exhaust valve turn the power on to operate the boiler. After about 6-7 Seconds, the electronic pump exhaust the air o with noise, and “CHECK” lamp on, the boiler stops.

Preparation and checking before starting to operate

Now press the power button on the panel repeatedly, and the oil ows out. Lock the valve and press the power button again, and the boiler gets ignited. In case that after removing air completely, the igni-tion has failed repeatedly about three times, contact the sales agency or the commercial agency.

Open the drain valve, and check out whether there is water in. Check out whether the pipes is lled with water.

Check out that the boiler is grounded to earth. (Don’t ground to the gas pipe or a lightening conductor)

Plug the power plug in the outlet. (Checking if the outlet power is 220V) Press the power button, and check out if “RUN” lamp turns on a little later.

How to use

Open the window door of the Operation and Display Panel and set the thermostat to the position you like.

Pressing the power button starts fan motor And the boiler gets started, turning the “COMBUSTION” lamp on.

If ignition fails and the operation stops. “check” lamp turns on, In this case, press the power button on the panel. In case that the ignition fails with pressing the power button four or ve times, contact the sales agency or the commercial agency.

CAUTION

When it doesn’t light even with the power button “ON” or it gets extinguished due to running out of oil, the FLAME Detector(Cds) gets to work and stops the operation

Combustion safety device

If water is insucient in the boiler, it interrupts the operation of the boiler with the power cut o. When water rells, the boiler starts again automatically.

Low water level blocking device

If the temperature of the boiler rises up too high, it is dangerous. So, in such case, this device cuts o the power automatically. When the overheating preventer gets to operated the combustion stops and “CHECK” lamp turn on. If the overhead temperature is fall “CHECK” lamp turn o and “RUN” lamp turning on automatically. If the operation stop is repeated again, contact the sales agency or the commercial agency.

Overheating preventer

During the hard winter, the circulation pump or the burner operates automatically to prevent the heating circuit from freezing. In winter, keep on plugging in the power cord and turning the power button “ON”. (the insulation state of the pipes must be normal)

Freezing preventer

If the power gets o, oil gets blocked automatically and the combustion stops.

Safety device on power-failure

Safety device

Check out whether the combustibles is near.

Keep cleaning all the time and don’t let the dust accumulated.

Check out whether oil leaks from, is stacked on, or soaks into the oil tank, oil pipes, the body of the boiler, etc. Check out whether there is any water leakage from the body of the boiler and the pipes.

Open the drain plug of the oil tank regulaly and remove water.

Points to be checked once or more a year

Everyday Checking

Cleaning of boiler

Much soot accumulated inside the boiler will reduce the life and eciency. At least once a year, clean the boiler inside.

Cleaning the oil filter

In case that the oil lter gets dirty, stop operating, lock the oil valve, and remove dust or rust accumulated below the oil cup. Detach the oil cup by rotating right and left. Pull down the lter.

Wash the lter and the inside of the oil cup with clean kerosene and light oil.

Cleaning the oil tank

Water may get mired in during feeding oil or get accumulated naturally during the long period in the oil tank. In this case, drain water o through the drain plug in the oil tank, and when oil starts to get out, lock it.

Cleaning the flame detector

If the light-receiving surface(sensing surface) gets darkened with soot, the bad sensitivity cause the wrong automatic operation.

You can pull out the ame detector(black) which is attached in the lower part of the burner.

Wipe the glassy surface of the ame detector with a scrap and x it in its position.

Checking the exhaust pipe

At least once a year,check for any loose joints in the discharge(piping and ue), clogging in ue, corrosion or leak. If any abnormality is found, contact out sales agency for checking up.(blocking pipes or holes, and so on)

For the place to install the boiler, choose the place possible to do the accompanying works, such as water supply works or electric works. For the place to install, choose the place conformed to the installation standards of the boiler and the construction act of the code of each city or municipality Install the boiler in the place as wide as possible for the maintenance and the re prevention. Install the boiler in the place convenient for controlling and manipulation of the temperature. If there is no electric outlet in the proper position, do wiring by requesting to a company designated by the electric power company. Around the installation place, there must be no place which stores and treats the combustibles and the inammables. There should be equipped drainage in the in stalling spot.

The distributor on the return water distributor side should be placed lower than the heating inlet. Connection should be made by installing a safety valve with 3.5kgf/偌 or lower opening the discharge piping to the cistern tank. The maximum operation pressure is 3.5kgf/偌. Do not supply water at a higher pressure or directly connect the water pipe having the pressure higher than. Overow of water during the heating to the cistern tank means short tank capacity. Exchange it with a larger one. Backow of water during the running or stopping of the circulation pump to the cistern tank is caused by too much air in the pipe. Remove air by opening valves on the distributor one at a time, while running the circulation pump. Evaporation at the cistern tank means failure in the system. Contact your representative to receive the check. Never install any valve between the boiler and the cistern tank. We will not be liable for any defect or breakdown caused by the failure to comply with the above precautions.
