(1) Heat and vaporized water are produced by the combustion process of this
kerosene heater.. This rating does not take into account heat loss due to
condensation of water vapor.
(2) Room size
for which this heater is suitable will vary depending on outside
temperature, house insulation,
window size, and other factors.
(3) External
tank to be purchased from local suppliers ..

SAFETY FEATURES
Your Laser 72 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
Circulation fan
Heat exchanger
Fuel nozzle
Igniter
Intake air
Blower motor
Burner mat
1. Flame Sensor
Heater will automatically stop all operations if ignition fails or if flame fails during combustion, in order to
prevent fuel overflow.. Warning lamp turns on
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. Warning lamp turns on ..
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 water-clear 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 22) ..
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 ..
RIGHT WRONG

SECTION C:
FUEL GUIDE
The Toyostove Laser 72 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 markedaccordingly 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 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 temper-
ature changes.
NEVER:
NEVER:
NEVER:
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.
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 un-
controllable flames, creating a severe fire hazard..

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 orrepair, now is the time to call your dealerandget it donebeforestorage ..
That way your heater will be ready for immediate use when the next heating season begins ..
3.. If you plan to store your heater in place,
(a) Unplug heater.
(b) Close the main tank valve ..
(c) Remove all kerosene from the fuel sump and clean the fuel strainer (see
page 13)
(d) Wipe off any stains or dust on heater with a damp cloth, then wipe once
again using a
dry cloth ..
(e) Cover heater completely with a large plastic bag to protect from dust.
4. To store heater in
another location,
(a) Unplug heater ..
(b) Close the main tank valve ..
(c) Remove all kerosene from the fuel sump and clean the fuel strainer (see
page 13).
(d) Disconnect fuel line and flue pipe from the heater..
Note: Kerosene remaining in the fuel line may flow out when fuel line is
disconnected
.. Have a container ready to catch drainage ..
(e) Remove any soot accumulated in the flue pipe using a brush and/or
vacuum cleaner ..
(f) Wipe off any stains or dust on heater with a damp cloth, then wipe once
again using a
dry cloth ..
(g) Put the heaterand flue pipe in the original shipping box, and store in a dry
place .. Iforiginal shipping boxis not available, cover the heatercompletely
