CANADA’S LEADER IN ENERGY PRODUCTS EQUIPMENT 5 REGULATORS DOMESTIC REGULATORS Second Stage Regulators Second stage regulators are used to satisfy the inlet requirements of the appliance and are typically designed to provide propane appliances with a delivery pressure between 9-13” W.C. As the second stage regulator of a 2 stage system, this model works with an inlet pressure usually between 4 to 10 PSI. This allows it to maintain a consistent delivery pressure to the load - regardless of ambient temperatures that affect the pressure of fuel in the storage tank. Line sizing from the outlet of the regulator is critical for proper performance, of which the B149 code book provides tables for. Fisher Second Stage Regulators Constructed of corrosion-resistant and wear-resistant materials, R600 Series Fisher Regulators are designed to provide a recommended replacement life of 20 years (a 30% improvement over previously existing designs). The R622 and 652 Fisher Regulators are designed to exceed the UL requirements of NFPA 58 by ensuring that the outlet pressure will never exceed more than 2 PSI – even in a double failure situation when used with the R622H series first stage regulators. The R622 Regulator offers a straight through design. The R652 Regulator is a 90° configuration with a ¾” back outlet for direct piping through the wall or into a meter set. The R222 Compact First Stage Regulators are built with the same features and benefits as the R622 series, but in a smaller body style. Features: • 1/8” F NPT pressure taps on the inlet and outlet for easy system pressure checks. • Large 3/4” drip-drip lip vent to reduce vent blockage and freeze-ups. • High capacity internal relief with built-in travel stop providing the best over-pressure protection in the industry. • Superior lock-up performance for precise and consistent performance. • Corrosion-resistant materials and coatings for durability. • Positive draining spring case. • 5 Year Warranty.
