SECTION C:
FUEL GUIDE
The Laser 73 is designed for use with clear paraffin only. Use of low-quality paraffin will cause burner
performance to drop, leading to abnormal combustion and reduced heater life.
Purchase only paraffin in non-red cans reserved exclusively for paraffin and marked accordingly with the
word “PARAFFIN”. Always store your paraffin in a separate area from where you store gasoline for your
power equipment to avoid accidental use of gasoline in your heater.
Clear Paraffin.
Paraffin 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
PARAFFIN.
Store away from direct sunlight, heat sources or extreme
temperature 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 paraffin; discard at the end of season.
In the living space.
¡Excess tar deposits on burner and flue pipe
¡Incomplete combustion
¡Reduced heater life
