SAFETY TIPS
BEFORE OPERATING YOUR HEATER, PLEASE review these safety tips:
RISK OF EXPLOSION
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 destructive fire. Even kerosene (paraffin) contaminated with small amounts of
gasoline (petrol), or similarly volatile materials, can be hazardous. Never use a can for
kerosene (paraffin) that has previously been used for gasoline (petrol), paint thinner,
methylated spirit, or solvents.
2. The appliance is to be used only with paraffin, class C1 burner fuel in accordance with
BS 2869.
3. 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.
4. 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.
5. NEVER fill heater fuel tank in living space. Fill heater tank outdoors. Never overfill your
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.
6. NEVER store or transport kerosene (paraffin) in other than a metal or plastic container that
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.
Store the kerosene (paraffin) out of reach of children in a safe container, marked
“KEROSENE” (“PARAFFIN”).
RlSK OF BURNS OR FIRE
1. Observe the heater carefully for 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 use heater to heat or boil water or as a cooking appliance.
DO NOT place cooking utensils, tea kettles or any other object on top of heater while in
operation.
4. To avoid possible burns or fire, do not move, refuel or attempt to service your heater
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.
5. DO NOT operate heater less than one (1) meter from walls, draperies, clothing, or
furniture. The operation of any heating appliance too close to such materials could cause
them to ignite, possibly resulting in a serious fire.
6. To avoid unstable burning, do not operate your heater in areas exposed to strong drafts.
DO NOT operate heater in high-traffic areas such as doorways or hallways where it may
be touched, jarred or tipped accidentally.
7. DO NOT operate heater in direct sunlight to avoid overheating, which may cause
abnormal flame behavior.
DO NOT allow room temperature to go above 25˚-30˚C. lf the room temperature exceeds
25˚-30˚C the flame may increase, thereby producing smoke.
8. Before going out, or at bedtime, turn the heater off, making sure the wick is in its lowest
position (see Extinguishing the Flame on page 8) and flame is completely extinguished.
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 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 mm (1 inch) 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 RCA-37WX is designed for use with high-quality kerosene (paraffin). Use of low-quality kerosene (paraffin) will
cause wick performance to drop, leading to “Iow flame” and “odor problem” conditions.
The kerosene commonly known as “industrial kerosene (paraffin)” is not suitable for your heater.
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.)
NEVER: Accidental introduction of water into fuel containers.
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.

Fuel gauge
1. Open the fuel tank lid on the top of heater cabinet and lift out the removable fuel
tank. Turn the removable tank upside down and remove the fuel tank cap.
2. Insert the straight tube of the manual siphon into the kerosene container. Insert
the siphon’s flexible hose into the removable fuel tank opening.
3. Turn the air vent knob on the top of the siphon clockwise to close the vent. Start
the flow of kerosene by squeezing the bulb of the siphon vigorously six or seven
times. Once flow begins, it is no longer necessary to squeeze the bulb.
4. Watch the fuel gauge on the removable tank to avoid overfilling. When it shows
half, stop flow by turning the air vent knob counterclockwise.
NOTE: Be careful to avoid overfilling the tank, especially with very cold kerosene.
Overflow might occur due to expansion when the fuel warms up.
5. Remove the siphon carefully, allowing excess kerosene to drain from the tube back into the container. Replace
fuel tank cap and tighten it securely. Be sure to wipe away any spilled kerosene from tank and other heater parts.
6. After making sure fuel tank cap is tightly fastened, invert tank and replace into heater body.
CHECK BEFORE LIGHTING
1. LEVEL THE HEATER
The heater should be operated on a firm, level floor.
NOTE: If your heater is not level, change locations.
DO NOT prop it with books or other objects.
2. ENGAGE THE AUTOMATIC EXTINGUISHER
The automatic extinguisher is engaged automatically by turning the wick adjuster
knob clockwise.

LIGHTING
NOTE: When you first use your new heater, ignite it out of the living area of your house, either in a garage or on area
outside protected from strong drafts. Burn it for about 15 minutes to remove all of the protective oil present
on the burner parts. If this 15 minutes “burn-in” is done inside, some objectionable odor will be observed.
This procedure is necessary ONLY THE FIRST TIME your ignite your heater.
NOTE:
If 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 30 minutes for the wick to become fully saturated.
1. Turn the wick adjuster knob clockwise until it stops.
It makes a spark discharge sound in the process of lighting procedure, but turn
the wick adjuster knob clockwise until it stops.
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 engages.
The wick adjuster knob can now move freely left or right to adjust the flame.
2. LIGHTING WITH A MATCH
You should not have to light the heater with a match, but should it become
necessary, open the grille, lift the heat chamber up by holding the wire handle 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.
NOTE: To restore the automatic igniter system to proper operation, replace worn out
batteries.
3. Be sure that heat chamber is properly seated by moving the wire handle left and
right. If the movement is cough and jerky, it indicates that the heat chamber has
not seated properly.
NOTE: An improperly seated heat chamber can cause high flame, smoke, and
potential damage to the heater itself.
DO NOT leave the heater until you have determined that the flame is burning
normally, which will be described in the following section.

DR-37_US.qxd 16.6.14 15:31 ページ 6

ADJUSTING THE FLAME
1. After lighting, wait for the heat chamber to reach operating temperature. This will take ten-fifteen minutes, after
which the flame will be visible through the glass cylinder.
2. CHECK THE FLAME LENGTH
Look at the flame and check its length. Flame length is not necessarily even or uniform around the circumference
of the center disk. Some areas may be lower than others, but on maximum wick height, flame length should
average between 1 cm (3/8 in.) to 2.5 cm (1 in.).
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 wick set TOO LOW or TOO HIGH. Doing so will decrease combustion effciency
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 its top bottom.
3. ADJUSTMENT OF MAXIMUM WICK HEIGHT.
After using the heater over a long period of time, you may observe that flame length in the heat chamber does
not reach its normal level several minutes after lighting. When this conditin is observed, it means that the wick
height needs adjusting using the unique wick life extender.
To adjust the wick height using the wick life extender mechanism, first release the
automatic extinguisher by pushing the manual shutoff button.
Pull the wick adjuster knob out completely. (It can be removed completely from
its shaft.)

The wick height adjuster knob, with three small holes marked 1, 2, and 3, can be
seen. The stem pin is engaged in one of the holes. Pull the control dial toward you
and change the location of the pin from 1to 2, or from 2to 3. Each step from
pin 1to 2will raise the maximum wick height by 2 mm per step. After this
adjustment, replace the wick adjuster knob.
When suitable flame length can no longer be achieved even on pin position 3, it is
time to clean and replace the wick. AFTER REPLACING THE WICK, CHECK THE
OPERATION OF THE AUTOMATIC EXTINGUISHER BEFORE LIGHTING YOUR
HEATER.
NOTE: NEVER use positions 2or 3until position 1no longer gives adequate
flame length.
EXTINGUISHING THE FLAME
1. Turn the wick adjuster knob counterclockwise until it stops. This requires about a
half turn. At this point, the flame is completely extinguished and the heater is off.
NOTE: DO NOT use the automatic extinguisher to routinely turn off the heater.
Automatic extinguishing should occur only when the heater is jarred or
tipped. Using the automatic extinguisher to turn off the heater will cause
odor, smoke and soot.
2. Make sure the flame is out completely.
3. DO NOT try to relight the heater for at least three (3) minutes after extinguishing it
off as this may cause smoke and odor.
MANUAL SHOTOFF
When quick shutoff is necessary, push the manual shutoff button.
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 shotoff.

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 on 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) Lift out the removable fuel tank before turning heater on. Raise the wick to its highest position, ignite heater as
usual, and allow the flame to consume the ramaining fuel in the fuel sub 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 cabinet as described in items 1 through 4 of the next section.
3) Remove any residue from the wick with a small brush such as an old toothbrush. Cinders or soot in the burner
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 holder 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 paper towels.
6) Reassemble the heater, following directions in item 15 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 from the removable fuel tank and the fuel sub tank. Dry the tank
thoroughly and refill with fresh, pure kerosene.
