MORRISON 244OM-0100AV 4" MALE CAST IRON EMERGENCY VENT

Model #: 244OM

Item #: 09-244OM-0100AV

UL Listed emergency vent (pressure relief only) used on aboveground storage tanks, as a code requirement, to help prevent the tank from becoming over-pressurized and possibly rupturing if ever exposed to fire. The vent must be used in conjunction with a “normal vent.” Correct application of this vent requires proper vent size and selection for the tank system in order to meet the specific venting capacity.

WARNINGS: The 244 emergency vent is for emergency pressure relief only and must be used in conjunction with a normal vent or pressure vacuum vent.
