SECTION C:
FUEL GUIDE
The OM-22 is designed for use with ASTM D3699 1-K Kerosene, ASTM D396 No.1 or No.2 Fuel Oil. 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, ASTM D396 No.1 or No.2 Fuel Oil in non-red cans reserved exclu-
sively for fuel and marked accordingly with the word “KEROSENE”, “NO.1 FUEL OIL”or “NO.2 FUEL 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.
What to Buy . . .
ALWAYS : Clean and high-quality ASTM D3699 1-K Kerosene, ASTM D396
No.1 or No.2 Fuel Oil.
ALWAYS : Fuel 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, clearly marked KEROSENE, NO.1 or
NO.2 FUEL OIL.
ALWAYS : Store away from direct sunlight, heat sources or extreme tem-
perature 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 fuel; discard at the end of season.
NEVER : In the living space.
Why It is Important . . .
Pure, clean fuel is essential for safe and efficient heater operation. Poor
quality or contaminated fuel 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 uncon-
trollable flames, creating a severe fire hazard.
Note: The fluidity of No.2 fuel oil becomes worse at temperatures of 21°F (-6°C)
and below and can “gel”. This condition will cause ignition failure.
