The following requirements shall apply:
- The pressure in oil lines to oil-burning equipment located above the lowest floor of a building shall not be more than is required to circulate oil to and from the burners, and all parts of the oil system shall be capable of withstanding the maximum working pressure in that part of the system.
- A remote control shall be provided to stop the flow of oil to any burner wherever located, and to any oil-burning equipment located on levels above the lowest floor in buildings. Such control shall be located outside the entrance to the room in which the burner is located and as close to such entrance as practicable, except that when an outside location is impracticable, such control may be located immediately inside the room in which the burner is located, provided such location is accessible at all times. All such controls shall be permanently labeled: "REMOTE CONTROL FOR BURNER," or as appropriate to the oil-burning equipment. On storage tanks of 60 gallons (227 L) or less capacity used with manually operated equipment, such remote control may be installed in the supply lines between tank and burner.
- In systems where either steam or air is used for atomizing the oil, the oil and the atomizing supply shall be interlocked so that where the supply of either is interrupted, the supply of the other will be immediately cut off.
