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...
SECTION D: OPERATION FUELING WARNING: CAUTION: Use KEROSENE only. Never use gasoline, thinner, benzene, light oil or waste oil. 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.
OPERATION CAUTION: • Hotter water increases the risk of scald injury. • Risk of scald injury. When using a shower, feel the temperature of the water you’re your hand before getting under the water. • 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. 1. Open the fuel tank valve. 2. Press “POWER SWITCH” to ‘‘ON’’. “POWER” lamp will come on.
FLOW RATE AND WATER TEMPERATURE SEASON SUMMER SPRING & FALL WINTER NOTE: INCOMING WATER TEMP 25ºC 15ºC 5ºC HOT WATER TEMP 50ºC (25ºC RISE) 50ºC (35ºC RISE) 50ºC (45ºC RISE) FLOW RATE 1260 L/h 900 L/h 700 L/h Whenever high temperature water is required for continuous demand, lessen the flow rate. Whenever low temperature water is required, the flow rate may be increased. TURNING UNIT OFF 1. Press “POWER SWITCH” to ‘‘OFF’’ position. All lamps will go out. 2. Close the fuel tank valve.
2. DRAINING WATER When you do not plan to use the unit for an extended period, the following procedures are recommended. 1. 2. 3. 4. 5. 6. 7. Turn the unit off. Disconnect the power supply cord. Close the fuel tank valve securely. After closing the main water supply valve, open up all the faucets. Open the drain valve on the bottom of the unit. Pull up the lever of the pressure relief valve. Press the drain valve of the pressure reducing valve.
SECTION E: ROUTINE MAINTENANCE INSPECTION AND MAINTENANCE WARNING: RISK OF INJURY FROM MOVING PARTS AND ELECTRICAL SHOCK. Disconnect the power supply cord before inspecting and servicing unit. All repairs should be left to professionals. RISK OF BACKFIRE AND INDOOR POLLUTION. Before operation make sure the exhaust pipe is free of snow, icing, leaves, bird’s nest or strong drafts. CAUTION: RISK OF BURN INJURY. Do not touch the exhaust pipe top and the exhaust pipe. When inspecting, ALWAYS do the following.
9. EXHAUST PIPE (ONCE A YEAR) A clogged exhaust pipe will cause improper combustion. Inspect for any clogging or soot accumulation should be done at least once every year. Make sure not to place combustibles in the exhaust pipe area. 10.PRESSURE RELIEF VALVE (ONCE A MONTH) The pressure relief valve may become immovable at times due to corrosion of pipes or mineral deposits In the pipes. Pull up the lever of the pressure relief valve every month and make sure the valve is movable. 11.
SECTION F: TROUBLESHOOTING WARNING: RISK OF INJURY FROM MOVING PARTS AND ELECTRIC SHOCK. Disconnect the power supply cord before servicing unit. All repairs should be left to professionals. Do not re-use the unit until the cause of the problems have been determined. CAUTION: RISK OF BURN INJURY. Do not touch the unit and the heat exchanger while in hot. If there Is any abnormality, determine for the causes from the list below and perform the specified measure.

SECTION C: INSTALLATION WARNING: WARNING: This unit must be installed in accordance with these instructions, local codes, ordinance and/or in the absence of local codes, the latest edition of the national fire protection association code. Check and comply with all state and local codes that may apply to water heater(s) before beginning the installation. This unit should be installed by a licensed, authorized person(s) due to the necessity of making electrical, water and fuel connections.
FUEL TANK INSTALLATION The fuel tank must be purchased separately and installed by a qualified fuel supply technician. NOTE: Fuel tank installation must comply with locally applicable codes. Check with local building officials. NOTE: Keep the fuel tank away from direct sunlight, high temperature, dust, rain and fire, and take preventive measures against falling during an earthquake. NOTE: The fuel tank should be installed on non-flammable objects, and kept level to prevent the unit from falling or shaking.
CAUTION: If metal fuel pipe is laid-out, be sure to clear away scraps or chips from the pipe which are produced during cutting or assembling. Leaving these scraps in the pipe may cause problem in the fuel pump. 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 procedure below: 1. Press “POWER SWITCH” to “OFF” position. Disconnect the power supply cord. 2.
CAUTION: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. In order to prevent the water heater from being broken or caused with a leak, regardless of being used in a cold region or in a warm or hot region, the cold water supply piping, hot water supply piping, drain pipe, pressure relief valve and pressure reducing valve are to be protected with sufficient insulation materials (by wrapping with heat insulation or by equipping an freeze prevention heater).
CAUTION: Do not allow pipes or valve to freeze. See the instruction manual, “PREVENTING FREEZE UP” of the page 11. Do not use the unit as an auxiliary heat source for the solar hot water heater, nor hydronic heating. ELECTRICAL WIRING WARNING: RISK OF FIRE AND ELECTRIC SHOCK. Make sure the power supply cord is disconnected to avoid any electric shock before servicing. Electric shock may cause serious injury. It is recommended that installation should be conducted by a licensed electrician.
INSTALLATION OF EXHAUST PIPE AND EXHAUST PIPE TOP WARNING: Make sure that exhaust pipe and exhaust pipe top are properly connected. If it is disconnected, exhaust gas leak indoor during operation which may cause danger. INSTALLATION OF EXHAUST PIPE AND EXHAUST PIPE TOP 1. Diameter of Exhaust Pipe The diameter (internal) of the Exhaust Pipe for the Water Heater is 106 mm. NOTE: The exhaust pipe is optional. 2.
10. Securing diagram of Exhaust Pipe and Exhaust Pipe Top installation NOTE: Put a semi-straight pipe or straight pipe in the Exhaust Pipe fitting hole at first, and lay transversely. NOTE: Select a place which is clear of combustible objects within 15 cm around the Exhaust Pipe Top, and 60 cm in the exhaust direction. And any opening such as the window or ventilation hole which can blow exhaust gas back indoors is not allowed on the wall as shown above. NOTE: Use corrosion and heat resistant steel. 11.
CHECK FOR EXHAUST PIPE AND EXHAUST PIPE TOP WARNING: Installation of Exhaust Pipe and Exhaust Top as shown below may cause an accident. Be sure to check once again after installation. Be sure to correct by following the installation presented below as an example in which a dangerous situation and incomplete combustion may occur.
SECTION D: TEST RUN PREPARATION 1. 2. 3. 4. 5. Make sure the exhaust pipe is installed properly. Make sure the fuel tank is installed properly. Make sure there is no fuel leakage.
