SECTION C:
FUEL GUIDE
The Water Heater is designed for use with water clean and high quality kerosene only. Use of
low-quality kerosene will cause burner performance to drop, leading to abnormal combustion
and reduced the unit life.
Always store your fuel in a separate area from where you store gasoline for your power
equipment to avoid accidental use of gasoline in your water heater.
What to Buy...
ALWAYS: Clean and high-quality KEROSENE.
ALWAYS: Fuel free of contaminants, water or cloudiness.
NEVER: Gasoline, alcohol, white gas, camp stove fuel or additives.
NEVER: Yellow or sour-smelling fuel.
How to Store It...
ALWAYS: Store in a clean container, clearly marked “KEROSENE.”
ALWAYS: Store away from direct sunlight, heat sources or extreme
temperature changes.
NEVER: In a glass container, or one that has been used for other
fuels.
NEVER: For longer than six months.
NEVER: In the living space.
Why It is Important...
Pure, clean kerosene is essential for safe and efficient water heater
operation. Poor quality or contaminated kerosene can cause:
- Excess tar deposits on burner and flue pipe
- Incomplete combustion
- Reduced unit life
Use of a highly volatile flammable fuel such as gasoline can produce uncontrollable flames,
creating a severe fire hazard.

11
SECTION D:
OPERATION
FUELING
WARNING: Use KEROSENE only. Never use gasoline, thinner, benzene, light oil or waste oil.
CAUTION: Make sure that the fuel is clean and free from dirt and water. Water and dirt may
cause combustion 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 Pipe run empty.
REMOVING AIR TRAP
When operating for the first time or when refueling an empty Tank, air may be trapped in the
Fuel Pipe, making ignition difficult. In this situation, follow the procedures below:
1. Turn the unit off by pressing “POWER SWITCH”. 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 Fuel 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. Plug into the receptacle. Tunn the unit on by pressing “POWER
SWITCH”.
NOTE: In the event of an ignition failure, Turn the unit off by
pressing “POWER SWITCH” and after 5 seconds press
“POWER SWITCH” once again.
INSPECTION BEFORE OPERATION
