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.

1.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.

2.Fuel Strainer

Special strainer catches any dirt 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 temperature 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 I.

1.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.

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

RIGHT WRONG

KEROSENE

GAS

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 is (1) acceptable for kerosene, (2) non-red in color, and (3) clearly marked,“KEROSENE”. Never store kerosene in the living space.

5.Operating Temperature Range

Use heater within the range of temperatures indicated in the right figure.

Point A: If outside temperature°F -20

than room temperature has to be 0°F or above

Point B: If outside temperature°F -45

than room temperature has to be 60°F or above

SECTION C:

FUEL GUIDE

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.

What to Buy . . .

ALWAYS : Crystal clear or red colored, 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 It . . . (when optional removable fuel tank is used)

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 temperature 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 : In the living space.

Why It is 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 uncontrollable flames, creating a severe fire hazard.
