SECTION C:
FUEL GUIDE
The Toyotomi BS-35(F) is designed for use with kerosene only. Use of low-quality kerosene will
cause burner performance to drop, leading to abnormal combustion and reduced the unit life.
Purchase only kerosene in non-red cans reserved exclusively for kerosene and marked
accordingly with the word ‘‘KEROSENE’’. Always store your kerosene 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: Kerosene 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, non-red in color, 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.

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 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, making ignition difficult. In this situation, 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. Plug into the receptacle. 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.
INSPECTION BEFORE OPERATION
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 pipes are securely connected and that there are no leaks.

though the temperature setting has not been changed. Special caution must be
taken if two faucets are open at the same time.
1. Open the fuel tank valve.
2. Press “POWER SWITCH” to ‘‘ON’’. “POWER” lamp will come on. Automatic operation is
based upon the temperature of water inside the heat exchanger. ‘‘BURNER’’ lamp is lit when
the burner is in its operation mode.
NOTE: When operating for the first time or after running out of fuel, ignition may not occur
because of air in the fuel line. In that case, remove air as described in the previous
section.
ADJUSTING WATER TEMPERATURE
CAUTION: • Hotter water increases the risk of scald injury.
• Risk of scald injury. When using a shower, feel the temperature of the water with
your hand before getting under the water.
• Risk of scald injury. Before changing the temperature setting, make sure that the
water heater is free from being used by any of your family at any place in-house.
• When using a large amount of hot water the temperature may change, even
though the temperature setting has not been changed. Special caution must be
taken if two faucets are open at the same time.
• The use of the water heater with the temperature selector knob at “MED” or
“LOW” may cause to propagate bacteria in water. In order avoid this, turn the
temperature selector knob to “HIGH” once a week to heat the water heater and
water at high temperature for approximately one hour.

watertemperature supplied. Use hot water supply faucet to control hot water
temperature, or readjust temperature setting.
• The hot-cold mixing faucet is recommended to be used for your harmless and
comfortable use of the water heater. Choose a mixing faucet which can provide a
pleasant feeling of water temperature with less temperature fluctuation.
• After installing the mixing faucet, turn to first set the temperature selector knob at
the position of “VERY HOT” and next gradually adjust the water temperature by
adding cold water to your preferable level. Sufficient care must be taken not to
misoperate this adjustment, which may cause to scald your hands.

NOTE: Since the water heater and piping system still have much air left after they are
drained, a flash flow of water may be caused by such air pressure when re-supplying
water through them. First open the valve carefully and gradually increase its opening
to “Full Open” when the water flow becomes stable. When air bubbles disappear in
the water, fully open the valve for hot and cold mixing faucet.
7. Also flow water through other hot and cold mixing faucets by the procedure of item 6
above.
8. Fully open the feed fuel valve for the fuel tank.
