1. Flame Sensor
Heater will automatically stop all operations if ignition fails or if flame failes during combustion, in order
to prevent fuel overflow. Error code will be displayed on the digital indicator.
2. Fuel Strainer
Special strainer catches any dust or impurities present in the fuel before it is sent to the burner.
3. Overheat Protector
Automatically stops all operations if heater cabinet reaches abnormally high temperatures due to motor
malfunction or abnormal combustion, in order to prevent fire.
4. Power Failure Recovery System
If power fails during heater operation, heater will turn off. When power resumes, heater will automatically
reignite to maintain the selected room temperature.
5. Fully Vented System
Flue pipe system provides outside air for combustion and vents all combustion products to the outdoors.
6. Fusible Link Valve
If a household fire should occur, bringing the fuel line or heater to extremely high temperatures, the fusible
link valve will stop the fuel supply to the burner. This will prevent the fuel supply from the external tank
continuing to flow into the house.
SECTION B:
SAFETY TIPS FOR OPERATION
CAUTION: Heater and vent pipe system must be properly installed before
operation. Please follow instructions under “Installation”, Section |.
1. Never use any fuel other than water-clear kerosene (ASTM No.1-K Kerosene).
NEVER USE GASOLINE. Use of gasoline can lead to uncontrollable flames,
resulting in destructive fire.
RIGHT WRONG
2. Due to high surface temperatures, keep heater away from children, furniture
and clothing while in operation {See Page 23).
3. To prevent abnormal operation and prolong heater life, be sure to perform
routine maintenance (See Pages 12—13).
4. Never store or transport kerosene in other than a metal or plastic container that 7
is (1) acceptable for kerosene, (2) non-red in color, and (3) clearly marked, Я
"KEROSENE". Never store kerosene in the living space.
5. Operating Temperature Range
- Use heater within the range of temperatures
indicated in the right figure. oo bon

SECTION C:
FUEL GUIDE
The Toyostove Laser 73 is designed for use with water clear No. 1-K kerosene only. Use of low-quality kerosene
will cause burner performance to drop, leading to abnormal combustion and reduced heater life.
Purchase only 1-K 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, ASTM No.1-K.
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: Watch fuel gauge to avoid overfilling heater.
How to Store It . .
ALWAYS : Store in a clean container, non-red in color, clearly marked
KEROSENE.
ALWAYS : Store away from direct sunlight, heat ‘sources or extreme temper-
ature changes.
NEVER: In a glass container, or one that has been used for other fuels.
NEVER: For longer than six months. Begin each heating season with fresh
kerosene; discard at the end of season.
NEVER: Inthe living space.
Why Itis Important...
Pure, clean kerosene is essential for safe and efficient heater operation. Poor
quality or contaminated kerosene can cause: |
® Excess tar deposits on burner and flue pipe
® Incomplete combustion
® Reduced heater life
Use of a highly volatile flammable fuel such as gasoline can produce un-
controllable flames, creating a severe fire hazard.

SECTION H:
LONG TERM STORAGE
At the close of each heating season, or when you do not plan to use your heater for an extended period, the
following procedures are recommended.
1. As the end of the season approaches, calculate your kerosene purchases so that you can use up all the
kerosene you have on hand. When kerosene is stored for over six months, its quality may deteriorate. The
use of such kerosene will have an unfavorable effect on heater operation.
2. If your heater needs any service or repair, now is the time to call your dealer and get it done before storage.
That way your heater will be ready for immediate use when the next heating season begins.

Fig. 4
NOTE: Heater should be installed on a sturdy floor. Should be level and flat.
NOTE: The template can be adjusted for use of non-standard installations such as the use of extension
pipe kits.
4. Cutthe hole for the standard flue pipe from inside the room. Use a 3-1/2" diameter hole saw attached to an
electric drill (See Fig. 5). The opening on the inside wall should be slightly higher than the outside opening
(approximately 1/2") so that the wall sleeve and the standard flue pipe will slope slightly downward
(approximately 3 degrees) after it is installed (See Fig. 6). This will enable the draining of condensed
moisture from the standard flue pipe to the outside and prevent rain or snow entering from outside after
installation.
