1.1 These requirements cover oil burners intended for firing appliances and devices such as boilers; central, floor, wall, and special furnaces; storage tank water, air, and direct-fired air heater units; and ovens. These burners are required to be equipped with automatic primary safety controls to restrict abnormal discharge of oil at the burner in case of ignition failure or flame failure.
1.2 The use of oil-burning equipment covered by these requirements are intended for installation in accordance with the National Fire Protection Association Standard for the Installation of Oil-Burning Equipment, NFPA 31, the International Mechanical Code, and the Uniform Mechanical Code.
1.3 Oil Burners covered by this standard are intended for use with one or more of the following grades of fuel oil/biodiesel blends as defined in the Standard Specification for Fuel Oils, ASTM D396:
a) No. 1 S15, No. 1 S500, No. 1 S5000, No. 2 S15, No. 2 S500, No. 2 S5000, No. 2, which may contain up to 5% biodiesel.
b) B6-B20 S15, B6-B20 S500, B6-B20 S5000 which are biodiesel blends that may contain up to 20% biodiesel.
c) B21-B100 which are biodiesel blends that may contain up to 100% biodiesel.
cd) No. 4, No. 4 (Light), No. 5 (Light), No. 5 (Heavy), No. 6.
Note: Unless stated otherwise it is implied that all sulfur grades are included for the fuel oil grade listed
