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 300 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.
