::b) Type 1 fuel oil is intended primarily for use in sleeve-type and wick-feed burners, excluding space heaters (see [[#9.1 Wick-type kerosene heaters|9.1]]), and in most vaporizing pot-type burner applications. It is also intended for atomizing burners in which Type 2 fuel oil cannot be used satisfactorily. During periods of lower ambient temperature, Type 1 fuel oil may be used in place of Type 2 to minimize waxing problems. | ::b) Type 1 fuel oil is intended primarily for use in sleeve-type and wick-feed burners, excluding space heaters (see [[#9.1 Wick-type kerosene heaters|9.1]]), and in most vaporizing pot-type burner applications.
