Congratulations; you are ready to begin enjoying the benefits of one of the most advanced kerosene (paraffin) heaters ever
made. TOYOTOMI, the leader in kerosene (paraffin) heater techonlogy, has tested and refined the KS-47B to assure you of
long-term safety and satisfaction. Please study the following instructions, use and care for your heater carefully, and it will
serve you well for many years. SAFETY TIPS
BEFORE OPERATING YOUR HEATER, PLEASE review these safety tips:
WARNING
RISK OF EXPLOSION
WARNING

1. Never use any fuel other than clean kerosene (paraffin).
Never use gasoline (petrol). Use of gasoline (petrol) can lead to uncontrollable flames resulting in a
destructive fire. Even kerosene (paraffin) contaminated with small amounts of gasoline (petrol), or
similarly volatile materials, can be hazardous. Never use for kerosene (paraffin) a can that has
previously been used for gasoline (petrol), paint thinner, or solvents.
2. Never refill heater fuel tank when heater is operating or still hot. To do so may cause a“flash back“
of flame to the fuel container, resulting in injury to yourself and your property.
3. Never use heater in areas where flammable vapors or gases may be present.Especially avoid use of
heater where gasoline (petrol), naphtha, acetone or other volatile solvents are in the air, or whose
containers are open. Such vapors could be ignited by the heater, resulting in fire and/or explosion.
4. Never fill heater fuel tank in living space. Fill heater tank outdoors. Never overfillyour heater.
Always replace heater tank cap securely after refueling. Spillage of kerosene (paraffin) produces
strong odor which is hard to remove. Spillage on carpet can be ignited if match or some other
ignition source contacts it.
5. Never store or transport kerosene (paraffin) in other than a metal or plastic containerthat is (1)
acceptable for kerosene (paraffin), (2) non-red in color, and (3) clearly marked, ”KEROSENE
(PARAFFIN)”. Never store kerosene (paraffin) in the living space. Picking up a gasoline (petrol) can
by mistake when fueling is a major cause of heater fires.
RlSK OF BURNS OR FIRE
1. Observe the heater carefully for fifteen to twenty (15-20) minutes after start-up.Problems of
improper adjustment of wick height or improperly seated heat chamber should become evident
during this warm up period.
NOTE: Carefully follow the instructions for lighting and adjusting the flame.
2. Due to high surface temperatures, keep away from children, furniture and clothing.

3. Do not operate heater without protective guards completely attached.
4. Do not use heater to heat or boil water or as a cooking appliance. Do not placecooking utensils, tea kettles
or any other object on top of heater while in operation.
5. To avoid possible burns or fire, do not move, refuel or attempt to service yourheater while it is burning
or still hot. If the heater is dropped while it is burning, fuel spillage and flames outside the heater may
occur.
6. Do not operate heater less than 90cm (3 feet) from walls, draperies, clothing, orfurniture. The operation
of any heating appliance too close to such materials could cause them to ignite, possibly resulting in a
serious fire.
7. To avoid unstable burning, do not operate your heater in areas exposed to strongdrafts. Do not operate
heater in high-traffic areas such as doorways or hallways where it may be touched, jarred or tipped
accidentally.
8. Do not operate heater in direct sunlight to avoid overheating, which may causeabnormal flame behaivor.
Do not allow room temperature to go above 30˚C. lf the room temperature exceeds 30˚C the flame may
increase, thereby producing smoke.
9. Before fueling, going out, or at bedtime, always turn the heater off, making sure thewick is in its lowest
position (see Extinguishing the Flame on page 10) and flame is completely extinguished.
WARNING
RISK OF INDOOR AIR POLLUTlON
Use heater only in well-ventilated areas. People with breathing problems should consult a physician before
using the heater.
”In a house of typical construction, that is, one that is not of unusually tight construction due to heavy
insulation and tight seals against air infiltration, an adequate supply of air for combustion and
ventilation is provided through infiltration. However, if the heater is used in a small room where less
than 5.7m3 (200 cubic feet) of air space is provided for each 250kcal (1,000BTU) per hour of heater
rating (considering the maximum burner adjustment), the door(s) to adjacent room(s) should be kept
open or a window to the outside should be opened at least 25.4mm to guard against potential buildup

of indoor air pollution. Do not use the heater in a bathroom or any other small room with the door
closed.”
FUEL GUIDE
The TOYOTOMI KS-47B is designed for use with high-quality kerosene (paraffin) only. Use of low-quality kerosene (paraffin) will
cause wick performance to drop, leading to ”Iow flame” and ”odor problem” conditions. Purchase only kerosene (paraffin) in
non-red cans reserved exclusively for kerosene (paraffin) and marked accordingly with the word ”KEROSENE (PARAFFIN)”.
Always store your kerosene (paraffin) in a separate area from where you store gasoline (petrol) for your power equipment, to
avoid accidental use of gasoline (petrol) in your heater.
What to Buy...
ALWAYS: Crystal clear, colorless, high quality KEROSENE (PARAFFIN).
ALWAYS: Kerosene (paraffin) free of contaminants, water or cloudiness.
NEVER: Gasoline (petrol), alcohol, white gas, camp stove fuel or additives. NEVER: Yellow or sour-
smelling fuel.
How to Use lt...
ALWAYS: Fill heater away from living quarters when heater is cool; use siphon.
ALWAYS: Check wick frequently for tar build-up. (Rapid, heavy build-up may indicate poor quality or
deteriorated fuel.)
ALWAYS: Watch fuel gauge to avoid over-filling heater.
How to Store lt...
ALWAYS: ln a clean container, clearly marked KEROSENE (PARAFFIN).
ALWAYS: AWAY FROM direct sunlight, heat sources or extreme temperature changes.
NEVER: ln a glass container, or one that has been used for other fuels. NEVER: For longer than 6
months. (Begin each heating season with fresh kerosene (paraffin); discard at the end of the season.)
Why lt is lmportant...
Pure, clean kerosene (paraffin) is essential for safe and efficient heater operation. Poor quality or
contaminated kerosene (paraffin) can cause:
Low flame
Excess tar deposits on the wick
Reduced wick life
Odor, smoke
Difficulty in igniting or extinguishing flame
Use of a highly volatile flammable fuel such as gasoline (petrol) can produce uncontrollable flames,
creating a severe fire hazard.

CAUTlON
Flames observed emerging from the heater body are a clear indication that fuel is dangerously contaminated with gasoline
(petrol) or other highly flammable material. If this occurs,
a. Never attempt to move the heater.
b. Call the Fire Department.
c. Use only a class ”B” fire extinguisher.
d. Never throw water directly on a burning heater.
OPERATING CONTROLS AND FEATURES
1. Safety Guard:
Prevents direct touch on the heat chamber, greatly reducing the possibility of accidental contact
burns to the heat chamber.
2. Heat Chamber:
Permits adjustment of heat output without increasing unwanted combustion materials or
reducing combustion efficiency. This feature increases comfort and convenience while
maximizing fuel savings.
3. Wick Adjuster Knob:
Used to raise and lower wick for heat output adjustment. To extinguish flame turn knob
counterclockwise.
4. Wick Life Extender:
Helps maintain good wick performance.
5. Igniter Lever:
Battery-powered electrical igniter is brought in contact with to ignite fuel at start-up. NOTE:
Lever should be pushed down gently.

6. Fuel Tank Cap:
Covers filling port of fuel tank.
NOTE: Wipe away any spilled kerosene (paraffin) from tank after filling.
7. Fuel Gauge:
Indicates fuel level in tank.
NOTE: Never fill beyond black line.
8. Manual Shutoff:
Used to rapidly retract wick and extinguish flame.
NOTE: To avoid odor and smoke, do not use routinely to turn heater off. This manual shutoff is
not effective when gasoline (petrol), gasoline (petrol)contaminated kerosene
(paraffin), or other highly flammable fuels are used in the heater.
9. Heat Chamber Handle:
Used to check and insure proper seating of the heat chamber after ignition.
lmproper seating of the heat chamber will cause erratic flame and smoke.

ASSEMBLY AND OPERATlON
lNSPECTlON AND ASSEMBLY
NOTE: Save the shipping carton and packing materials for future storage of your heater.

1. REMOVE PACKING MATERIALS
Remove all packing materials from your heater and install the guard as follows:
CAUTION: Risk of burns. Do not operate heater without guard completely attached.
a) Remove the carrying handle, top plate and packing materials.
b) Replace the top plate and install carrying handle by inserting end of carrying handle to the guard
as per illustration.
2. lNSTALL DRIP TRAY
NOTE: DO NOT operate your heater without the drip tray.
Place the drip tray on the floor.
Place the heater on the drip tray.
Turn the heater clockwise until the feet slide into their tabs.
3. CHECK SCREWS
Make sure that the three (3) screws around the guard above the fuel tank are tight.
4. INSTALL BATTERIES
Insert the two (2) C size batteries according to the plus (+) and minus (-) markings inside the holder.
FUELING
WARNING: Use only clean Kerosene (paraffin).
Never use gasoline (petrol) or other flammable liquids.
ALWAYS extinguish heater before refill heater fuel tank. Fuel heater
outside the living area.
1. lnsert the straight tube of the manual fuel siphon into the kerosene (paraffin) container. Remove the fuel tank cap on the
heater, and insert the siphon's flexible hose into the fuel tank opening.
USE KEROSENE ONLY
(PARAFFIN)

2. Turn the air vent knob on the top of the siphon clockwise to close the air vent.
3. To start the flow of kerosene (paraffin), squeeze the bulb of the siphon vigorouslysix or seven times.
Once the flow begins, it is no longer necessary to squeeze the bulb. To avoid overfilling the tank,
watch the fuel gauge. As the indicator enters the red zone, stop the flow by turning the air vent
knob counterclockwise.
NOTE: Be especially careful to avoid overfilling the tank with very cold kerosene; otherwise
overflow might occur when the fuel warms up.
4. Remove the siphon carefully, allowing the excess kerosene (paraffin) to drain from the tube back intocontainer. Replace the
fuel tank cap and tighten it securely. Be sure to wipe away any spilled kerosene (paraffin) from tank or other heater parts.
CHECK BEFORE LIGHTING
1. LOCATE YOUR HEATER AWAY FROM WALLS AND AVOID DRAFTS
Allow at least three 90cm of clearance between the heater and walls, curtains, shelving or other combustible materials. Do
not operate your heater in drafty areas or locations where opening doors may create gusts of air. Drafts or strong air currents
may make flame unstable and affect heater performance.
2. LEVEL THE HEATER
The heater should be operated on a firm, Ievel floor.
NOTE: lf your heater is not level, change Iocations. Do not attempt to prop it up with
books or other objects. An unlevel heater may burn with an uneven flame.

3. CHECK THE WICK LIFE EXTENDER
On your first use of new heater or after replacing the wick, check if the WICK LIFE EXTENDER if it
on position 1. If not, relocate the WICK LIFE EXTENDER to position 1 by following the instructions
on page 9, ADJUSTMENT OF WICK HEIGHT WITH WICK LIFE EXTENDER.
4. ENGAGE THE AUTOMATIC EXTINGUISHER
The automatic extinguisher is engaged automatically by turning the wick adjuster knob clockwise.
Check the operation of the automatic extinguisher before lighting your heater. After turning the
wick adjuster knob clockwise until it stops, turn the manual shutoff counterclockwise to be sure
the wick moves smoothly down.
LIGHTING
NOTE: When you first use your new heater, ignite it out of the living area of your house, either in a
garage or an outside area protected from strong drafts. Burn it for about 15 minutes to remove all of the protective
oil present on the burner parts. lf this 15 minutes ”burn-in” is done inside, some objectionable odor will be observed.
This procedure is necessary ONLY THE FIRST TIME you ignite your heater.

NOTE: lf you have fueled your heater for the first time, or if you are refueling it after it has been out
of fuel for a long time, you will need to wait about thirty (30) minutes for the wick to become
fully saturated before Iighting. Failure to allow enough time for the wick to become fully
saturated may cause permanent damage to the wick when it is lighted.
1. Turn the wick adjuster knob clockwise until it stops. This raises the wick to itsmaximum height. As
the wick rises within the heater, the wick adjuster knob turns with some resistance and makes a
sound like the winding of a clock. Once the wick has reached its proper height, the automatic
extinguisher is fully engaged. The wick adjuster knob will now move freely left or right to adjust the
flame.
2. AUTOMATIC LIGHTNG
Gently push down the igniter lever. The igniter coil should glow and touch the wick. When flame
appears, release the igniter lever.
NOTE: If you have diffculty igniter wick, let up on the igniter lever very slightly to remove the igniter
coil from direct contact with the wick.
3. LIGHTING WITH A MATCH
Tilt the heat chamber and touch the match to the top of the wick. Do not allow burned parts of the
match to fall or remain on the wick.
4. Be sure that heat chamber is properly seated by moving the wire heat chamberhandle left and right.
NOTE: An improperly seated heat chamber can cause high flame, smoke, and potential damage to
the heater itself. Proper seating of the heat chamber is essential for good performance. Do
not leave the heater until you have determined that the flame is burning normally, as
described in the following section.
ADJUSTING THE FLAME
1. After lighting, wait for the heat chamber to reach operating temperature.
2. CHECK THE FLAME LENGTH
After ten to fifteen (10-15) minutes, the entire heat chamber should be glowing red.
BAD GOOD BAD
CORRECT
Most efficient Produces odor
and soot combustion
lf necessary, raise or lower the wick by turning the wick adjuster knob to produce the proper flame condition.

NOTE: Do not operate your heater with wick set TOO LOW or TOO HIGH. Doing so will decrease combustion efficiency and
increase production of unwanted emissions. When operating heater, be sure wick is high enough to keep the primary
heat chamber heated to a uniform red glow from top to bottom.
NOTE: AIways observe the heater closely for the first 15-20 minutes after it is lighted to be sure it is properly adjusted.
3. ADJUSTMENT OF WICK HEIGHT WITH WICK LIFE EXTENDER
Normal use of the wick and heat chamber over a period of time may it impossible to achieve a satisfactorily high flame level.
Usually this occurs because the wick develops deposits on it that retard fuel flow and evaporation.
When this happens, the wick should be cleaned by “burning dry” as described in item 2, page 11 “CARE AND MAINTENANCE”.
When the “burning dry” cleaning procedure is no longer effective in restoring proper flame height,
adjust the wick life extender mechanism to the next higher position.
NOTE : Do not move the wick life extender to a higher position unless the wick has been cleaned
by “burning dry”.
To adjust the wick height rising the wick life extender, first release the automatic extinguisher by
pushing down on the MANUAL SHUTOFF.
Then pull the wick adjuster knob from its shaft by pulling outward.
When the wick adjuster knob is removed, the wick life extender control can
be seen to contain 3 sequential holes marked 1 , 2 and 3. By pulling out and
turning the control dial counterclockwise, the stem pin of the adjuster can
be moved from 1 to 2 and to 3 position as required. Each step upward from
a lower to a higher number increases the maximum wick adjustment range
by 2 mm (approx. 1/13 in.).
After the wick life extender‘s dial has been set, be sure the MANUAL SHUTOFF knob is
in the “OFF” position. Replace the wick adjuster knob, making sure it is engaged securely on the wick adjuster shaft.
Repeat steps 1 through 3, as needed, in the section titled “ADJUSTING THE FLAME”. When
suitable flame length can no longer be achieved even on pin position 3 , the wick should be
replaced.
NOTE : Do not move adjuster to higher position until lower position no longer gives adequate flame
length, even after “burning dry”.
Before replacing wick, be sure to move the wick life extender dial back to its 1 position.
CHECK THE OPERATION OF THE AUTOMATIC EXTINGUISHER BEFORE LIGHTING YOUR HEATER.

EXTINGUISHING THE FLAME
1. Turn the wick adjuster knob counterclockwise until it stops. Within a fewmoments, the flame will
be completely extinguished and the heater will be off.
2. Make sure the flame is out completely.
3. Do not try to relight the heater for at least three (3) minutes after turning it off,as this may cause
smoke and odor.
MANUAL SHUTOFF
When quick shutoff is necessary, push the manual shutoff down.
NOTE: For routine turn-off, DO NOT use the "Manual Shutoff" or activate the ”Automatic
Extinguisher” by jarring the heater. These methods may cause unwanted odor, soot and
smoke. Only the wick adjuster knob should be used for normal shutoff.
CARE AND MAINTENANCE
As with any good appliance, preventive as well as corrective maintenance is occasionally required. Please read the following
section carefully in order to enjoy the greatest benefits from your heater.
INSPECTlON OF THE WlCK
NOTE: One of the simplest but also the most important components of your heater is the wick.
With proper attention, the wick will last at least one heating season and, depending on the quality of the fuel used,
possibly longer, it helps to perform routine maintenance operations of the wick.
1. lndications that the wick may need attention are:
low flame
tar deposit on the top edge of the wick
difficulty in turning the wick adjuster knob
a flickering or dying flame
2. Clean the wick by burning dry as follows:
1) When the fuel gauge indicates empty, but the heater is still burning, raise the wick to its highestposition and allow the
flame to consume the remaining fuel in the tank.
NOTE: Burning the wick dry can at times create odors. For the burning dry procedure, remove your heater from the living area
of your house into a well-ventilated area such as a garage or even a sheltered area outside. If you burn the wick dry
outside, be sure that the heater is not exposed to strong drafts during the procedure.
2) After the heater has cooled completely, remove the heater cover as described in items 1 and 2 of thenext section.

3) Remove any residue from the wick with a small brush such as an old toothbrush. Cinders or soot in theburner around the
wick may be vacuumed away. Be careful when removing such material from the wick with a brush, to do so gently so as
not to tear the top surface of the wick.
4) Remove any tar deposits on the top of wick adjuster and primary air tube using a scraper.
NOTE: When good wick performance is no longer achieved by the burning dry process, it may be necessary to replace the
burned wick with a new one.
5) Before reassembling the heater, take a few minutes to wipe the parts with a soft cotton cloth or papertowels.
6) Reassemble the heater, following directions in item 11 of the next section.
NOTE: If the flame is still low after cleaning the wick, the wick may contain some water. It is then necessary to replace the
wick and empty all kerosene (paraffin) from the fuel tank. Dry the tank thoroughly and refill with fresh, pure
kerosene (paraffin).
INSPECTION OF THE IGNITER COIL (EVERY TIME)
If the wick does not igniter or is hard to ignite, check if the igniter filament is broken.
If the igniter coil is found to be defective, replace as described on page 14.
REPLACEMENT OF PARTS
REPLACING THE WlCK
USE ONLY GENUINE TOYOTOMI ”KS-47B” REPLACEMENT WlCK. SUBSTITUTE WICKS CAN SEVERELY REDUCE PERFORMANCE AND
SAFETY.

5. Place the wick adjuster on its side. Next, line up the three (3) openings in thewick adjuster: 1) the holes in the sleeve, 2) the

diagonal slots in the fixed part of the wick adjuster, and 3) the slots in the moving part of the wick adjuster controlled by
the wick adjuster knob.
6. Fold the new wick in quarters and insert it into the wick adjuster from wickadjuster bottom. Place one of the pins in one of
the lined-up openings. lf you experience difficulty, gently turn the wick adjuster knob clockwise. Then insert the two other
pins, turning the wick adjuster knob if necessary. Do not bend the sleeve.
7. Finally, gently press the wick, all along its circumference, against the adjusterto insure that it is firmly in place.
8. Lower the wick adjuster into the fuel tank, guiding the tail of the wick so it fitsover the primary air tube and evenly into
place.
Point the wick adjuster knob to the front of the heater. Insure that the wick adjuster is centered over the studs on the fuel
tank.
NOTE: The space between the wick adjuster and the primary air tube should be even all around.
NOTE: Make certain the top of the wick adjuster and the top of primary air tube are the same height. lf they are uneven,
the flames tend to be uneven, too.
9. Tighten the four (4) wing nuts around the wick adjuster.
10. Turn the wick adjuster knob to be sure the wick moves smoothly up and down.
AFTER REPLACING THE WICK, CHECK THE OPERATlON OF THE AUTOMATlC EXTINGUISHER.
Wick height on position 1 of the wick life extender should be 8mm when wick adjuster knob is
turned fully cIockwise. Be sure to check.
NOTE: Remember always to start a new wick on position 1 of the wick life extender.
