Point A:
Point B:
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 D3699 1-K
Kerosene, ASTM D396 Low Sulfur No.1 Fuel Oil, ASTM D975 Ultra Low Sulfur
Diesel (ULSD), or Ultra Low Sulfur Heating Oil (ULSHO)). 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 26).
2.
To prevent abnormal operation and prolong heater life, be sure to perform
routine maintenance (See Pages 16).
3.
Never store or transport kerosene in other than a metal or plastic container that
is clearly marked, “KEROSENE”, “No.1 FUEL OIL”, “ULTRA LOW SULFUR
DIESEL”, or “ULTRA LOW SULFUR HEATING OIL”. Never store fuel in the living
space.

FUEL GUIDE
Clean and high-quality ASTM D3699 1-K Kerosene, ASTM D396 Low
Sulfur No.1 Fuel Oil, ASTM D975 Ultra Low Sulfur Diesel (ULSD), or
Ultra Low Sulfur Heating Oil (ULSHO).
Fuel 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,
No.1 FUEL OIL, ULTRA LOW SULFUR DIESEL, or ULTRA LOW
SULFUR HEATING OIL.
Store away from direct sunlight, heat sources or extreme tempera-
ture 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
fuel; discard at the end of season.

Why It is Important . . .
Good, clean fuel is essential for safe and efficient heater operation. Poor quality or
contaminated fuel can cause:
Use of a highly volatile flammable fuel such as gasoline can produce
uncontrollable flames, creating a severe fire hazard.
Note: The fluidity of Ultra Low Sulfur Diesel and Ultra Low Sulfur Heating Oil becomes
worse at temperatures of 21˚F (-6˚C) and below and can “gel”. This condition may
cause ignition failure. To prevent congealing it is recommended to use an additive
with the fuel. Check with a fuel supply company for the proper additive and mix.
GAS
The Toyostove Laser 730/Laser 730AT is designed for use with ASTM D3699 1-K kerosene, ASTM D396 Low Sulfur
No.1 Fuel Oil, ASTM D975 Ultra Low Sulfur Diesel (ULSD), or Ultra Low Sulfur Heating Oil (ULSHO). Use of low-
quality fuel will cause burner performance to drop, leading to abnormal combustion and reduced heater life.
Purchase only ASTM D3699 1-K kerosene or ASTM D396 Low Sulfur No.1 Fuel Oil, ASTM D975 Ultra Low Sulfur Diesel
(ULSD), or Ultra Low Sulfur Heating Oil (ULSHO) in non-red cans reserved exclusively for kerosene and marked
accordingly with the word “KEROSENE”, “No.1 FUEL OIL”, “ULTRA LOW SULFUR DIESEL”, “ULTRA LOW SULFUR
HEATING OIL”. Always store your fuel in a separate area from where you store gasoline for your power equipment to
avoid accidental use of gasoline in your heater.

6. Recommended Periodic Maintenance
As a state-of-the-art furnace, your heater requires periodic inspection and service by an authorized technician
to insure optimum, trouble free performance. This inspection should include: a combustion check; flue pipe
check; burner assembly check; cleaning all necessary parts and replacing gaskets as needed. Please ask
your authorized Toyostove dealer for details and scheduling. When using Ultra Low Sulfur Diesel (ULSD) or
Ultra Low Sulfur Heating Oil the heater should be serviced at least every two years because the distillation of
ULSHO is heavier than 1-K Kerosene and No. 1 Fuel Oil. When using 1-K Kerosene or Low Sulfur No. 1 Fuel
Oil your heater can be serviced less frequently.
AUTOMATIC IGNITER CLEANING SYSTEM
When the heater is on and clock is set (see “set Clock” on page 9), it will automatically stop and clean the igniter
every day at 2:00 AM and will display “CL” on the digital indicator. After the cleaning mode is finished the heater will
automatically re-ignite and continue to burn again.
The igniter cleaning mode helps prolong the igniter life.

At the end 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 fuel purchases so that you can use up all the fuel you
have on hand. When fuel is stored for over six months, its quality may deteriorate. The use of such fuel 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.
3. If you plan to store your heater in place,
(a) Disconnect power supply.
(b) Close the main tank valve.
(c) Remove all fuel from the fuel sump and clean the fuel strainer.
(d) Wipe off any stains or dust on heater with a damp cloth, then wipe once
again using a dry cloth.
4. To store heater in another location,
(a) Disconnect heater.
(b) Close the main tank valve.
(c) Remove all fuel from the fuel sump and clean the fuel strainer.
(d) Disconnect fuel line and flue pipe from the heater.
Note: Fuel 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 heater in the original shipping box, and store in a dry place. If original shipping box is not
available, cover the heater completely with a large plastic bag to protect from dust during storage.
