SAFETY FEATURES
Your Laser 73 is equipped with the following safety features. Please familiarize yourself with these features.
When your heater is extinguished due to a safety mechanism, be sure to identify and correct the problem.
Flame Sensor
Heater will automatically stop all operations if ignition fails or if flame fails during combustion, in order
to prevent fuel overflow. Error code will be displayed on the digital indicator.
Fuel Strainer
Special strainer catches any dirt or impurities present in the fuel before it is sent to the burner.
Overheat Protector
Automatically stops all operations if heater cabinet reaches abnormally high temperature due to motor
malfunction or abnormal combustion, in order to prevent fire.
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.
Fully Vented System
Flue pipe system provides outside air for combustion and vents all combustion products to the
outdoors.
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 C:
FUEL GUIDE
The Toyostove Laser 73 is designed for use with clear or red colored 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.
Crystal clear or red colored, high-quality KEROSENE, ASTM
No.1-K.
Kerosene free of contaminants, water or cloudiness.
Gasoline, alcohol, white gas, camp stove fuel or additives.
Yellow or sour-smelling fuel.
Store in a clean container, non-red in color, clearly marked
KEROSENE.
Store away from direct sunlight, heat sources or extreme tempe-
rature changes.
In a glass container, or one that has been used for other fuels.
For longer than six months. Begin each heating season with
fresh kerosene; discard at the end of season.
In the living space.
¡Excess tar deposits on burner and flue pipe
¡Incomplete combustion
¡Reduced heater life

B. Burning mode lamp “MED”will start to flash after approx. 3 - 9 minutes
and ignition will take place. (*) After ignition, burning mode lamp “MED”
will change from flashing to continuous. And, after 10 seconds, burning
mode lamp will turn to “LOW”and heater will start “LOW”burning mode.
Circulation fan will turn on after approx. 3 minutes.
Note: (*) Pre -heating depends on the room temperature.
Room temperature: below 34°F - 9 minutes
34°F - 61°F - 6 minutes
over 61°F - 3 minutes
C. Heater will operate at “LOW”or “MED”burning mode for approx. 6 min-
utes after ignition, regardless of temperature control setting. Heater will
not go into “HIGH”burning mode while the prepurging is in effect. After
this period, output can be adjusted as desired by using the ”NORMAL”
temperature selector as directed in following instructions.
3. Adjusting Room Temperature
A. Slide “NORMAL”temperature selector to set the room temperature
desired. The temperature control should be set at the position you find
most comfortable.
Note: Desired temperature setting will be displayed on the digital
indicator when you set the room temperature.
Note: The scale on temperature selector is just for your reference. The
figures on the digital indicator and on the scale may not match
exactly; This is normal.
B. Burning mode will be regulated automatically in accordance with the room temperature registered by
the room temperature sensor. Heater will be operated at “HIGH”burning mode until room tempera-
ture reaches the selected temperature level.
C. When room temperature reaches the selected setting, heater will automatically shift to “MED”or
“LOW”burning mode to maintain the desired temperature.
When room temperature exceeds the selected setting by approx. 4°F, the heater will automatically
shut off. As room temperature drops, the heater will automatically re-start to maintain the desired
temperature.
