Note 1. If the number of 100 lb. LP gas capacity cylinders in a multicylinder installation at a consumer site is greater than eight, the minimum distance shall comply with the appropriate portion of this table, applying the aggregate capacity rather than the capacity per container. If more than one installation is made, each installation shall be separated from another installation by at least 25 feet. Do not apply the minimum distances between aboveground containers to such installation.
Note 2. The filling connection and the vent from the liquid level gauges in containers, filled at point of installation, shall be not less than ten feet in any direction from air openings into sealed combustion system appliances or mechanical ventilation air intakes.
Note 3. The discharge from safety relief devices shall be located not less than three feet horizontally away from any building opening which is below the level of such discharge.
Whenever containers are discharging into a common manifold, the aggregate water capacity shall be used in determining the safety clearances; except that, when not more than three containers, none of which have an individual water capacity greater than 1,000 gallons, are manifolded, the individual capacity of the largest container shall be used in determining the safety clearances. (See Table 15-26-700.)
