SAFETY FEATURES

Your Laser 56 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.

GAS

Heater and vent pipe system must be properly installed before operation.

Please follow instructions under “Installation”, Section I.

Never use any fuel other than clear or red colored kerosene (ASTM No. 1-K
Kerosene). NEVER USE GASOLINE. Use of gasoline can lead to
uncontrollable flames, resulting in destructive fire.

1.

Due to high surface temperatures, keep heater away from children, furniture
and clothing while in operation (See Page 24).

2.

To prevent abnormal operation and prolong heater life, be sure to perform
routine maintenance (See Pages 12

-

13).

3.

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.

4.

Operating Temperature Range

SECTION C:
FUEL GUIDE

GAS

The Toyostove Laser 56 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.

Fill heater away from living quarters when heater is cool; use
siphon.

Watch fuel gauge to avoid overfilling heater.

Store in a clean container, non-red in color, clearly marked
KEROSENE.

Store away from direct sunlight, heat sources or extreme
temperature 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

desired temperature setting.

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

minutes 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 temper­ature 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.
