1.WARNING:
FAILURE TO INSTALL, MAINTAIN, AND/OR
OPERATE THIS KEROSENE HEATER ACCORD-
ING TO MANUFACTURER'S INSTRUCTIONS MAY
RESULT IN CONDITIONS WHICH CAN PRODUCE
BODILY INJURY AND/OR PROPERTY DAMAGE.
NOTE: The WARNING and IMPORTANT
Instructions appearing in this manual are not meant
to cover all possible conditions and situations that
may occur. It must be understood that common
sense, caution, and carefulness are factors which
cannot be built into this heater. These factors must
be supplied by the person(s) installing maintaining,
or operating the kerosene heater.
Always contact your dealer, distributor, service
agent, or the manufacturer on any problems or
conditions you do not understand.
2.WARNING: RISK OF EXPLOSION
* NEVER use any fuel other than clear or red dyed
No. 1-K kerosene. NEVER use fuel such as
gasoline, benzene, paint thinners or other oil
compounds in this heater.
* NEVER refill heater fuel tank when heater is
operating or still hot.
* NEVER use heater in areas where flammable
vapors or gases may be present.
* NEVER fill heater fuel tank in living space; fill tank
outdoors.
* NEVER store nor 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; kerosene should be stored in a well
ventilated place outside the living area.
* The unit is EXTREMELY HOT while in operation.
Due to high surface temperatures, keep children,
clothing, furniture, and other combustible objects
at least 36″away from top and front area.
* RISK OF INDOOR AIR POLLUTION
USE HEATER ONLY IN WELL VENTILATED
AREAS. People with breathing problems should
consult a physicianbeforeusing 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 (5.7 m
3
) of air
space is provided for each 1,000 BTU per hour of
heater rating (considering the maximum burner
adjustment), the door(s) to adjacent room(s)
should be kept open or the window to the outside
should be opened at least 1 inch (25.4 mm) 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.
* NEVER use heater to heat or boil water nor use as
a cooking appliance.
3.WARNING: RISK OF FIRE
NEVER use gasoline in this heater.
4.NEVER leave heater operating if you intend to leave
for any period of time. Always make sure to turn
heater off and inspect to insure that it is completely
extinguished prior to going to bed.
5.NEVER Ieave heater unattended. NEVER use as a
source of heat for drying objects.
6.NEVER place objects on the top plate.
7.If poor quality kerosene is used, so much carbon will
be accumulated on the upper part of the wick that it
may not move down, a strong odor will be
generated and shorter wick life will result; therefore,
careful attention should be paid to the kerosene
quality. When lowering the wick, make certain fire is
out. (For details, see Extinguishing on page 6.)
8.Adjustment of room temperature, when the room
becomes too hot, should be carried out by
ventilation such as opening a window, but never by
means of the wick adjuster knob. If heat is reduced
excessively by means of the wick adjuster knob, it
will cause imperfect combustion, thereby resulting in
accumulation of carbon, and odor will be generated.
9.CAUTION: RISK OF BURNS
NEVER operate the heater without the guard or
grille completely attached.
10.Do Not Mix Old and New Batteries.
Do Not Mix Alkaline, Standard, or Rechargeable
Batteries.

Take the heater, kerosene, and siphon pump outdoors for fueling. Tighten the
air-tight cap located on the top of the siphon; insert the straight tube into the
kerosene container, place the flexible hose through the opening of the fuel
tank. Squeeze the bulb rapidly, which will lift fuel from the kerosene container
into the heater tank. (see fig.9&9A)
Watch the fuel gauge on the base of the heater to determine the amount of
kerosene transferred from container to heater. When you approach the full
mark, loosen the airtight cap on the siphon, which will stop the flow of
kerosene.
Allow the siphon to drain before removing it from the tank and the container.
Replace the tank cap and the kerosene container cap securely. Thoroughly
wipe up any spilled kerosene.
VERY IMPORTANT: Allow a minimum of 60 minutes (use a timer) for
kerosene to completely saturate the wick and eliminate any air pockets
which might otherwise occur before lighting the heater for the first time.
III. FUELING

The first time the heater is lit, it should be done outdoors to allow residues of
oils and waxes used in manufacturing the heater and the wick to burn off. This
will eliminate any odors from this initial light up from collecting inside the home.

Produces smoke
and soot
TOO LOW

CORRECT
Most efficient
combustion
V. WICK ADJUSTMENT
Observe the heater flame during this initial light up. During the first 5 minutes, flames will gradually build
up and appear at the top of the burner. As the burn chamber warms, the kerosene fuel will vaporize from
the wick more easily. After 5-7 minutes, you will be able to use the wick adjuster knob to correctly
position the flames at the top of the burner so that no more than
1
/ 2 ″to
3
/ 4 ″of flames appear,
distributed evenly around the circumference of the flame spreader disk located in the center top of the
burner. Four notches will appear in the flame where the crossbars in the burner deflect the air flow.
Because of changes in heater temperature and in room temperature, subsequent adjustments
will be required after 60 minutes and periodically thereafter.
IV. AUTOMATIC IGNITION SYSTEM
IGNITION BY MATCH
The heater has been designed to be lit by using the automatic ignition system.
This system consists of 2 "C" cell batteries, connecting wires, a manual arm
which holds the igniter itself and which, when pushed, raises the burner and
brings the igniter in contact with the wick after the wick has been raised to its
maximum height.
The ignition sequence is as follows: Open the door below the mica window.
Push in the auto start knob, The burner will be lifted up and the igniter coil will
appear and begin to glow. Hold the auto start knob in and turn the wick adjuster
knob clockwise to raise the wick. As the wick approaches the glowing igniter
ignition will occur. As soon as flames are observed through the open door,
release the igniter knob which will lower the burn chamber back down over the
wick. It is important to rotate the burner knob left and right, back and forth, a
few times to insure that the burner is properly located on the wick adjuster.
Should you experience difficulty with the igniter mechanism or dead batteries,
the heater can be lit using a match. This is done by raising the wick, lifting the
burner using the burner knob, and applying a lighted match to the exposed top
edge of the wick.(see fig.12)
CAUTION: Be sure to remove the match or any broken portions of it from the
burner area. A match head left in place can cause misalignment of the burner
which may result in incomplete burning, odor, soot, or fire.

VI. EXTINGUISHING THE HEATER
NOTE: The flames must be adjusted so that they are neither too high nor too low in order to obtain
proper combustion. Basic adjustment of the flame is controlled by using the wick adjuster knob to raise
or lower the wick. A fine adjustment of the flame can be made by grasping the burner knob and moving
the burner from side to side and front to back until the bright yellow-white flames appearing at the top of
the burner are as even as possible. After each adjustment, allow a few seconds time for the flames to
stabilize.
IMPORTANT NOTE: During the burning period, heat which builds up inside the body of the heater will
gradually warm first the burner, then the wick adjuster mechanism, and finally the kerosene located in the
tank of the heater itself. As this warming occurs, more and more kerosene will vaporize which in turn may
require further downward adjustment of the wick in order to maintain the flames at the
1
/ 2 ″height above
the burner. Because of this need for adjustment from time to time, the heater should never be left
unattended and should be extinguished before going to bed or leaving your home.
To extinguish, grasp the wick adjuster knob with one hand and push down
the manual shutoff with the other hand. You will feel a strong spring
tension attempting to rotate the wick adjuster knob counterclockwise and
lower the wick. By relaxing your grasp slightly, allow the spring to gently
lower the wick and extinguish the flames. When the spring action stops,
confirm the wick has been fully lowered by turning the wick adjuster knob
counterclockwise as far as possible. Allow 10-15 seconds, open the door
on the body of the heater, lift the burner with the burner knob, and confirm
that no flickering flames are present and the heater is fully extinguished.
(fig.13)
NOTE: Once the heater has been extinguished, wait 10 minutes before
re-lighting. The 10-minute cooling off period allows the heater to return to
normal condition and prevents the creation of a strong odor which will occur if
an attempt is made to immediately relight an extinguished heater.
WARNING: After a period of use, tar and carbon may build up on the wick,
interfering with its smooth lowering into the body of the heater. This could result
in the flames not extinguishing completely. It is the owner's responsibility to
inspect and maintain the wick to prevent such a hazard from occurring.
Because the risk of fire and/or carbon monoxide poisoning, never attempt to save kerosene or reduce
the amount of heat produced by your heater by operating it at a wick setting below the minimum Wick
Stop setting, or showing less than
1
/ 2 ″ -
3
/ 4 ″of flame around the circumference of the flame spreader
disk.

VII. WICK MAINTENANCE VERY IMPORTANT !
VIII. CARBON REMOVAL/DRY BURNING
Carry out the "Carbon Removal" outdoors if windless, on a porch or the like, or in a room with
window(s) open because a strong odor is produced.
(a) With the fuel tank having only a small amount of kerosene, keep the wick burning without refilling
with kerosene even when the tank becomes empty. When the flame starts to burn out, raise wick
fully and leave it there untill it burns out. Wait approximately 60 minutes, then relight the wick
with a match if necessary, and allow it to burn out again. When it cools, remove any remaining ash
with an old toothbrush.
(b) The upper part of the wick will be cleared from carbon with this operation and softened; however, if
any parts are still stiff, pinch them by means of small pliers to fracture the carbon into pieces,
supply a small amount kerosene to tank and once more perform the "Carbon Removal." After the
carbon has been removed, refill tank and wait 60 minutes before igniting wick.
Carry out the "Carbon Removal" within 5 to 7 days after the first use of the kerosene heater. This will
reduce carbon accumulation to the wick. Thereafter perform the "Carbon Removal" every 5 or 6
tank fulls of kerosene.
If any water gets into the tank, or when the kerosene heater season comes to an end, completely remove
all kerosene from the fuel tank. VERYIMPORTANT!
NOTE: "CARBON REMOVAL" SHOULD BE DONE WEEKLYDURING THE HEATING SEASON
UNLESS NEEDED MORE FREQUENTLY. CHECK TO BE SURE.
The top of a fiberglass wick accumulates carbon in the process of burning kerosene. This must be
removed to maintain peak efficiency in burning. It is most important that you feel for carbon hardness after
the second or third tankful of fuel. Awick in good condition will feel soft while one that is carbonized will
feel like a bristle brush or, in late stages, the top could be coated with hard black carbon.
Check for resistance when turning the wick adjuster knob; check if flame height is correct; check if it
is difficult to ignite by the igniter. Any of these troubles result from carbon on the upper part of the wick.
To get rid of carbon, perform the "Carbon Removal" in the following procedure.

Rotating the wick control knob clockwise
turns the pinion at the other end of the wick
control shaft and causes the rack mounted
along the outer circumference of the wick
frame to turn. This results in the wick
being lifted to the top of the wick holder
assembly. As the wick rises, the torsion
spring mounted on the wick control shaft
is put under tension and compressed. The
wick can be contacted by the igniter when
in the full "up" position. It is held there
against the tension of the torsion spring by
the latch that engages the ratchet mounted
on the wick control shaft. Pressing the
manual shutoff lever downward releases the
latch, allowing the torsion spring to rapidly
lower the wick. The descent of the wick can
be slowed by lightly grasping the wick control
knob. Lowering the wick slowly in this
manner reduces the likelihood of a kerosene
odor.
FUNCTION OF THE AUTOMATIC SAFETY SHUTOFF DEVICE
The safety shutoff device is built into the wick raising and lowering mechanism. It is a primary safety
system in a kerosene heater. Its purpose is to prevent the spread of flame should a heater be accidentally
tipped over while in use.
It functions in the following manner. When the pendulum starts to swing because of a shock, it causes
the latch to be retracted from the wick control shaft ratchet. This permits the torsion spring to quickly
retract the wick to the fully lowered position. The resulting quick drop puts out the flame.

IMPORTANT: For the automatic safety shutoff mechanism to function as intended, the wick must be
free of gummy tar deposits. This can be accomplished by regularly "dry burning" the wick as described
on page 7 under "Wick Maintenance" and "Carbon Removal / Dry B urning ."
CAUTION
The operation of the automatic safety shutoff mechanism should be checked periodically, i.e., once a
week during the heating season. This can be done by using the wick control knob to raise the wick
to the fully upright position. DO NOT LIGHT THE WICK FOR THIS TEST. Grasp the upper corners of
the protective grille and give the heater a firm shake. If the safety shutoff is working correctly, you will
hear a loud snap as the latch disengages from the ratchet and the torsion spring quickly drops the wick.
Now attempt to rotate the wick control knob counterclockwise. A correctly functioning automatic tipover
device will lower the wick completely. If you are able to lower the wick further, this indicates it is time
to "dry burn" for carbon and tar removal again.
NOTE: Every time the wick is removed and replaced, the safety shutoff must be tested to insure it
is operating properly.
XI. LONG TERM STORAGE
(1) Agitate and rinse inner part of the tank with a little of the remaining kerosene, then pour out entirely.
Water never mixes with kerosene, and it causes rust inside the tank. Remove all kerosene.
(2) With the kerosene out of the fuel tank, ignite and keep the wick burning. Keep the wick fully turned
up until it burns out (about an hour).
(3) Detach the body, burner and batteries. Remove the wick adjuster from the fuel reservoir, dry the
inside of the fuel tank thoroughly. Remove the carbon accumulated on the wick adjuster and/or the
soot adhering to the burner with a brush or screwdriver.
(4) After cleaning, reassemble the heater. Remember to reassemble the wick adjuster so as to keep the
gap between the wick adjuster and wick guide cylinder equal all the way around. Refer to page 8
"Wick Replacement."
(5) The batteries should be taken out from the battery case because they may leak and corrode the
kerosene heater.(see fig.22)
(6) Store the kerosene heater with the tipover extinguishing device deactivated and the wick lowered
down.
(7) Put the kerosene heater in the original box with original packing ( reassemble the guard ) and keep it
in a well-ventilated place. Also keep the Owner's Manual with heater.(see fig.23)
Store the kerosene heater carefully using the following procedure so it will operate safely next season.

KEROSENE
Locating and using proper kerosene is the single most important thing you, the owner, can do to ensure
your satisfaction in the use of the heater. The correct grade of kerosene will be labeled 1-K, which
means it has been carefully refined to eliminate virtually all but the merest trace of sulphur. Sulphur
causes the "rotten egg" smell. Kerosene containing sulphur will cause your heater to produce a
disagreeable odor and make using it unpleasant.
All heaters will produce a slight odor on start up and turn down. This is normal, unavoidable, and to be
expected. Some people are much more sensitive to this odor than others. Once your heater has reached
its proper operating temperature (7-10 minutes) and is operating normally, there is no odor.
Kerosene may be purchased either crystal clear or dyed red. Kerosene deteriorates rapidly in storage,
so fresh kerosene should be used at all times. Kerosene is easily contaminated by water which
condenses in the fuel seller's tank. You can test kerosene for water by tilting your container and drawing
four cups from the lowest part of the container into a clear glass jar. Let it sit for a few hours and then
examine the bottom of the jar for little pin-heads (or BB's) which are actually water droplets. Water
droplets will infiltrate your wick, but cannot pass through it. Instead, they block the flow of kerosene
causing your heater to not burn properly.
If you buy kerosene in bulk, be certain to store it in a blue container. NEVER store kerosene in a red
container which is the universal symbol for gasoline. NEVER attempt to use any other fuel such as
gasoline, alcohol, white gas, or camping stove fuel in your kerosene heater. These fuels are very volatile
and can cause uncontrolled flames.
Kerosene deteriorates with age and will not burn properly in the heater. It should be stored away from
direct sunlight or other sources of heat. NEVER store kerosene in your living quarters.
A kerosene heater cannot function properly if the kerosene is contaminated with even a small amount of
water. Water is frequently present in kerosene which is purchased from bulk storage. This water is due to
condensation and comes out of the air which replaces kerosene when a large tank is emptied. For this
reason, it is better to buy bulk kerosene from a dealer who dispenses it from a 55-gallon drum.
When purchasing kerosene in bulk, you must rely on the reputation of your dealer. Even the best dealer
can occasionally receive a "bad batch" from his fuel distributor.
Poor quality kerosene, kerosene contaminated with water or traces of other fuel oils, or kerosene with
more than a very small trace of sulphur can cause: odor and smoke, low flame, difficulty in lighting or
extinguishing the heater, excessive tar deposits on the wick, reduced wick life. If you experience any of
the above, the first thing to do is check your kerosene. If there is any doubt as to its quality, dispose of it
properly and retest your heater using a gallon of prepackaged kerosene.
Kerosene stored below 40
o
F will not vaporize easily and will not produce the expected amount of heat
until it has warmed up in the tank of the heater in which it is being used. The best idea is to store the
heater itself, or a tank full of kerosene, indoors if you intend to use your heater under severe winter
conditions in a shed, garage, or ice-fishing house.
Kerosene in the USA is sometimes dyed red due to tax laws and the red dyed kerosene should be
translucent (able to be seen through) and not cloudy.
First Choice:
Second Choice:
Third Choice:
Prepackaged 1-K Kerosene
55-Gallon Drum
Bulk Kerosene from a Large
Tank ( either stored in the ground
or elevated above ground )
For people who are sensitive to normal
kerosene odors, or experience "fumes" during
the operation of their heater, we recommend
Clear Lite
TM Synthetic Fuel manufactured by
Exxon Chemical Co. It is completely odorless
and is safer to store than kerosene.
