::b) Type 1 fuel oil is intended primarily for use in sleeve-type and wick-feed burners, excluding space heaters (see [[CGSB_ONGC/003_0002_2019_ENG#9.1 |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.

::c) Type 2 fuel oil is a heavier distillate than Type 1 and is intended for use in most atomizing-type burner applications. This type of fuel oil is used in most domestic oil burning appliances and in some medium capacity commercial and industrial burners. Type 2 may contain up to 5% biodiesel (See [[CGSB_ONGC/003_0002_2019_ENG#Annex C|Annex C]] ).
