Congratulations; you are ready to begin enjoying the benefits of one of the most advanced kerosene heaters ever made.
TOYOTOMI, the leader in kerosene heater techonlogy, has tested and refined the KS-27A 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
1. Never use any fuel other than water-clear kerosene.
Never use gasoline. Use of gasoline can lead to uncontrollable flames resulting in destructive fire.
Even kerosene contaminated with small amounts of gasoline, or similarly volatile materials, can be
hazardous. Never use a can for kerosene that has previously been used for gasoline, paint thinner,
or solvents.
2. Never refill heater fuel tank when heater is operating or still hot. To do so maycause 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, 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 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 in other than a metal or plastic container that is (1) acceptable
for kerosene, (2) non-red in color, and (3) clearly marked, ”KEROSENE”. Never store kerosene in the
living space. Picking up a gasoline can by mistake when fueling is a major cause of heater fires.
RlSK OF BURNS OR FIRE
1. Observe the heater carefully for 15-20 minutes after start-up. Problems of improperadjustment 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.
WARNING

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 going out, or at bedtime, turn the heater off, making sure the wick is in itslowest position (see
Extinguishing the Flame on page 9) 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 200 cubic feet (5.7m3) of air space is provided for each 1000 Btu 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-27A is designed for use with high-quality kerosene only. Use of low-quality kerosene will cause wick
performance to drop, leading to ”Iow flame” and ”odor problem” conditions.
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 heater.
What to Buy...
ALWAYS: Crystal clear, colorless, 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 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.
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; discard at the end of the season.)
Why lt is lmportant...
Pure, clean kerosene is essential for safe and efficient heater operation. Poor quality or contaminated
kerosene 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 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
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. 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.
2. Safety Guard:
Extensive grillework covers the hot surfaces of the heater, greatly reducing the possibility of
accidental contact burns.
3. Wick Adjuster Knob:
Used to raise and lower wick for heat output adjustment. To extinguish flame turn knob
counterclockwise.
4. Fuel Tank Cap:
Covers filling port of fuel tank.
NOTE: Wipe away any spilled kerosene from tank after filling.
5. Fuel Gauge:
Indicates fuel level in tank.
NOTE: Never fill beyond black line.

6. 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, gasoline-contaminated kerosene, or
other highly flammable fuels are used in the heater.
7. 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 carrying handle.
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.
FUELING
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, squeeze the bulb of the siphon vigorously six orseven 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 to drain from thetube back into container. Replace the fuel tank
cap and tighten it securely. Be sure to wipe away any spilled kerosene from tank or other heater parts.
CHECK BEFORE LIGHTING
1. LOCATE YOUR HEATER AWAY FROM WALLS AND AVOID DRAFTS
Allow at least three (3) feet 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.
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 minute ”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.
