SECTION D:

OPERATION

WARNING: Use ASTM D3699 1-K Kerosene, ASTM D396 Low Sulfur No.1 Fuel Oil, or ASTM D975 Ultra Low
Sulfur Diesel (ULSD) only. Never use gasoline, thinner, benzene, light oil or waste oil, or any
other high volatile liquids.
CAUTION: Make sure that the fuel is clean and free from dirt and water. Water and dirt may cause com-
bustion failure and shorten the life of components such as the fuel pump.Be sure to refuel
before the tank runs out. Avoid having the fuel tank and fuel line run empty.
REMOVING AIR TRAP
When operating for the first time or when refueling an empty tank, air may be trapped in the fuel line, mak-
ing ignition difficult. In this situation, after removing the trapped air thoroughly from the fuel filter at the fuel
tank outlet, follow the procedures below:
1. Press "POWER SWITCH" to "OFF" position. Disconnect the power supply
cord.
2. Release the two (2) screws from the front panel and remove the front
panel.
3. To catch the fuel which will drain out, put a small container under the
strainer.
4. Loosen the screw on top of the strainer. Immediately wipe off any spilled
fuel.
5. Remove the trapped air thoroughly. Failure to remove all the air will cause improper ignition and may
extinguish the unit.
6. Tighten the screw after removing trapped air.
7. Reconnect the power supply cord. Press "POWER SWITCH" to "ON" position.
Note: In the event of an ignition failure, press "POWER SWITCH" to "OFF" position and after
10 seconds press "POWER SWITCH" to "ON" position once again.
1. Before turning on the POWER SWITCH, make sure that the water supply inlet is open and that water runs
out properly by opening a hot water faucet. If not, check the drain valve to see if it has been left open.
2. Check for water leaks in the pipes.
3. Be sure there is a sufficient amount of fuel in the tank and that there are no leaks in the pipe line.
4. Be sure the power supply is properly connected and grounded to the unit.
5. Be sure the area around the water heater is clear of flammable materials such as gasoline, thinner or
flammable vapors.
6. Be sure the exhaust and flue pipes are securely connected and that there are no leaks.
7. Do not operate the unit without water in the heat exchanger. The heat exchanger may be damaged.
