Basic regulator with full-capacity internal relief and overpressure, underpressure shutoff and /" NPT vent. Basic regulator, non-relieving with overpressure shutoff and /" NPT vent. Basic regulator, non-relieving with overpressure, underpressure shutoff and /" NPT vent. To prevent regulator damage and possible personal injury, pressures must not exceed: Maximum inlet pressure, normal service (P ): Depending on orifice size, up to PSIG. See table on page. Maximum outlet pressure, normal service (P ): Depending on spring selection, up to PSIG. See Pressure Spring table on page. Maximum inlet pressure for abnormal or emergency service, without causing damage to regulator case is 7 PSIG. Maximum outlet pressure which can be contained by pressure carrying components (no flange leakage to atmosphere except for normal relief action) is 0 PSIG. Remove from service if regulator is subjected to these conditions. Maximum outlet pressure for abnormal service without damage to internal components is 0 PSIG. Remove from service if regulator is subjected to these conditions. Do not connect the inlet of the regulator to a pressure source higher than that recommended. Never connect the regulator outlet to the pressure source. Observe the flow direction arrow on the valve body. If inlet pressure can exceed the maximum regulator outlet pressure rating, some form of over-pressure protection in addition to internal relief may be required. Install, operate, inspect and maintain the regulators as outlined in the following instructions and in accordance with your company's policies and applicable federal, state, and local codes and laws. Failure to follow these instructions may result in damage to the regulator or personal injury Check installation location for suitability. Physical changes may have been made to the building site since the original installation. Examine regulator for shipping damage. Check regulator and piping for foreign matter which may have accumulated during shipment or handling. Check regulator information stamped on seal plug to determine if regulator is suitable for intended service. See page. Suitable stop valve(s) should be installed and conveniently located. Filters are available from Elster American Meter for applications where pipeline contaminants are believed to be present. Regulators may be used at temperatures between -0 F and +0 F (-0 C and +6 C).

4 00B Series Service Regulators 0 Elster American Meter Installation! WARNING Inside Installation: A vent line of sufficient diameter to carry gas vented by the regulator to a safe outside location away from any opening in the building is required. For all sizes of regulators, a /" threaded vent is provided for a vent line. Do not thread a pipe into the vent more than seven turns so as to not block the vent flapper. Outside Installation: Care must be taken to prevent vent opening from freezing closed, becoming blocked, or allowing water to enter from any cause. Particular consideration should be given to sites where flooding, snow, or freezing rain may be experienced. The vent or vent line port should point vertically downward, and overhead protection should be used where necessary. c. d. e. f. g. h. i. j. k. Turn gas on slowly. Establish a low flow rate between to SCFH. Remove seal plug (). Turn pressure spring adjustment screw () clockwise to increase outlet pressure; counterclockwise to decrease outlet pressure. Establish the outlet pressure within the range limits of the pressure spring used. To test for the regulator's ability to fully shut off (lock-up), shut off all flow downstream of the regulator. At lock-up, the outlet pressure will be somewhat higher than the set pressure. However, if the pressure continues to rise after seconds, the regulator must be repaired. Observe for 0 seconds. When the set pressure has been properly adjusted, depressurize and remove gauge(s) and lines. Replace seal plug (). Pressurize and check all connections for leaks. (Numbers in parentheses refer to Figure.).... Remove all shipping plugs from the valve body. Use good piping practice. Be sure piping and regulator are free of dirt, pipe dope and other debris. Apply pipe dope to male threads only. Install regulator. Make certain it is installed correctly with inlet pipe connected to the inlet regulator connection and flow is in the direction as indicated by arrow located on valve body (). Elster American Meter suggests that the vent point downward to prevent entry of water and debris. By removing the four valve body bolts (), the diaphragm case () may be rotated in 90-degree increments in relation to the valve body (). Replace and tighten the four valve body bolts () to 60 ±0 in. lbs. A regulator installed within a building should be located as near as practical to the point of service line entrance. If the regulator is equipped with an overpressure shutoff or Universal Safety Shutoff Assembly (USSA), see page 7 for setting instructions. Make sure inlet pressure is always less than the maximum recommended inlet pressure for the orifice size. See Maximum Recommended Inlet Pressure table on the right. Turn gas on slowly. If an outlet valve is used, it should be opened first. Do not subject the regulator to a sudden surge of inlet pressure. Assure that there are no leaks and all connections are tight. The 00B Series regulator is preset at the factory. Should you decide to adjust the set pressure, perform the following: a. b. Turn gas off and depressurize the system. Install outlet pressure gauge.

5 00B Series Service Regulators 0 Elster American Meter Inspection Inspection of Valve Seat Disc and Orifice (Numbers in parentheses refer to Figure.) CAUTION Regulators are pressure-control mechanisms having numerous moving parts which can wear. In addition, regulator damage may occur from external sources. For these reasons, the regulator should be periodically inspected and checked for proper operation. The frequency of inspection will depend on the severity of the service conditions and the requirements of applicable local, state, and federal codes and regulations. Inspection and maintenance of the 00B Series regulator have been simplified for practical reasons. Repair parts are offered if maintenance of the regulator is required. Inspection of the valve seat disc and orifice valve may be performed in the field. Follow the procedure described below. Care should be exercised to prevent foreign matter from entering the regulator. Shut off gas supply and depressurize the system. Remove four valve body bolts (), securing the diaphragm case () to the valve body (). Separate the diaphragm case from the valve body. Visually check the seating edge of the orifice inside the valve body (). If it is nicked or damaged, it should be replaced with a new orifice to provide positive shut off. See maintenance instructions for replacing orifice. Inspect the surface of the valve seat disc (). If it is scored or uneven, replace it as outlined in the maintenance instructions for replacing the seat disc. Install new seal ring () in the diaphragm case groove. Inspect unit for cleanliness and proper positioning of the parts. Pay particular attention to the proper positioning of the seal ring () in the groove. Install the diaphragm case () on the valve body (). Make sure the vent is positioned so that it cannot become plugged or allow water to enter. Replace and tighten the four valve body bolts () to 60 ±0 in. lbs. Proceed to Steps, and 6 of the installation instructions. Maintenance!
