§ 59-10. Location of tanks., Chapter 59. Oil Burners, Code of Ordinances, Floral Park

Inside storage, gravity and auxiliary pressure tanks shall be mounted on substantial incombustible supports and be adequately secured to avoid strains on piping and shall not be located within 10 feet measured horizontally from any fire source or flame.

The aggregate capacity of exposed storage tanks installed in a cellar or basement and used in connection with one complete system shall not exceed two tanks of 275 gallons' capacity each.

Tanks of 60 gallons' capacity and less may be used under pressure provided they shall be designed for six times the maximum working pressure and shall be proved tight at twice the maximum working pressure. Working pressure shall not exceed 50 pounds per square inch. Pressure tanks shall be equipped with a reliable pressure gauge and an automatic relief valve piped to discharge by gravity to the storage tank.

Where gravity feed is permitted from one 275 gallon tank only, the oil supply line must be equipped with a quick-closing valve held open with a fusible link placed near the burner.

Storage tanks having a capacity greater than 550 gallons may be placed in the cellar or basement of any building below the level of the floor provided that they are so placed that the top of the tank is not less than 12 inches below the level of the floor.

Tanks located outside of the building underground shall be so placed that the top of the tank is not less than two feet below the surface of the ground except that, in lieu of the two feet cover, tank may be buried under 12 inches of earth and a cover of concrete at least six inches in thickness provided; reinforcements shall extend at least 12 inches on all sides of the tank.

Where tanks are located so that the top of the tank is above the level of the suction inlet of the pump supplying oil to the burner or burner assembly, a siphon-breaking device consisting of an anti-siphon valve, a vacuum tank "Underwriters" vacuum siphon-breaker, siphon-breaking pump set or equivalent devices to prevent siphoning, shall be installed.

A manual control valve, either globe or gate, with hand-wheel, must be placed in the oil supply line immediately upon entering the basement.

The outside fuel-oil storage tank and the piping connected thereto shall not be covered until the same has been inspected and approved by the General Foreman. Request for such inspection must be made sufficiently in advance to permit inspection during regular hours.

An anti-siphon valve or equivalent must be placed in the supply line next to the manual-control valve unless a wall pump is used or unless the top of the fuel-oil tank is below the level of the burner. This anti-siphon device must be pressure- or vacuum-actuated and not the type held open by fusible link closing only at the time of fire.

No tank shall be installed under public sidewalks or public roadways unless permit has been granted by the Board of Trustees of the Village of Floral Park, Nassau County, New York.
