521.11 GAS CONTAINERS.
   (a)    Butane or bottled gas systems of not less than 100 pound containers shall include the container base or bracket, containers, container valves, connectors, manifold valve assembly, regulators and relief valves.
   Such containers shall not be buried below ground. However, this shall not prohibit the installation in a compartment or recess below grade level, such as a niche in a slope or terrace wall which is used for no other purpose, providing that the container and regulating equipment are not in contact with the ground and the compartment or recess is drained and ventilated horizontally to the outside air from its lowest level, with the outlet at least five feet away from any building opening which is above or below the level of such outlet. Except as provided for use of gas for industrial applications where oxygen is not required, the discharge from safety reliefs shall be located not less than five feet horizontally away from any building opening which is above or below the level of such discharge. Discharge from any safety relief device shall not terminate in any building, nor beneath any building unless such space is well ventilated to the outside.
   Containers shall be set upon firm foundations or otherwise firmly secured; the possible effect on the outlet piping of settling shall be guarded against by a flexible connection or special fitting.
   Regulators and low pressure relief devices shall be protected against accumulation of water, ice and snow.
   (b)   After the owner or lessor of the system has been notified of defective installation in accordance with this section, each day shall constitute a separate offense.
