The Fisher 912 series LP-gas pressure regulators are designed for use on small portable outdoor appliances. They are direct-operated, spring loaded regulators that can be used in a variety of first-stage service and industrial applications. These regulators have limited-capacity internal relief across the diaphragm to help minimize overpressure.

Underwriters Laboratory (UL) requires horizontally mounted regulators to be installed with vent opening protection to prevent blockage by freezing rain.

Fisher equipment must be installed, operated and maintained in accordance with Federal, state, and local codes and Fisher instructions. Only personnel trained in the proper procedures, codes, standards and regulations of the LP-gas industry should install and service this equipment.
