The Fisher R232 integral two-stage regulators contain a non-adjustable first-stage regulator on the inlet, and choice of second-stage outlet range for small domestic loads. The second-stage portion has a high capacity internal relief valve for overpressure protection; the first-stage does not have an internal relief valve. The compact size of this unit makes it ideal for tight fit applications and installations where piping distance is short.
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.
