The second stage provides 11-inches water column (27 mbar) outlet pressure. The second stage portion has a high capacity internal relief valve construction. The first stage does not have an internal relief valve. The regulators are normally painted GRAY. First Stage and 2 PSI (0,14 bar) Service Regulators The Types R622H, R622-E, and R652E regulators are designed for high pressure (pounds per square inch) vapor service. These regulators have high capacity internal relief valves. When used on first stage service, the Type R622H regulator'reduces container pressure to 10 psig. (0,69 bar) for a second stage regulator. On final stage service the regulator reduces container pressure for a high pressure burner. The regulator is normally painted RED. The Type R622E or R652E standard outlet pressure setting is 2 psig (0,14 bar). The regulator is painted PALM GREEN with a WHITE CAP. It is an intermediate stage regulator that reduces 10 psig (0,69 bar) first stage pressure to 2 psig (0,14 bar). They are used on 2 psig (0,14 bar) pressure systems, The Types R622E and R652E are not suitable for first stage service.

Regulator with Vent Pointed Down Indoor installations can cause a hazardous accumulation of gas which could result in personal injury'Or property damage. Dever use a Type R622H, R622E or R652E (pounds to pounds) regulator on low pressure (inches of water column) service because personal injury or property damage could occur. The Types R622E and R6 ,2E are, not suitable for use as a "first stage" regulator. General Installation Instructions Before installing the regulator, Check for damage, which might have occurred in shipment. Check for and remove any dirt or foreign material, which may have accumulated in the regulator body. Replace old pigtails. Blow out any debris, dirt or capper sulfate in the copper tubing and the pipeline. o Apply pipe compound to the male threads of the pipe before installing the regulator. • Make sure gas flow through the regulator is in the same direction as the arrow on the body. "Inlet" and "Outlet" connections are clearly marked. installation Location The installed regulator should he adequately protected from vehicular traffic and damage from other external sources. • Install the regulator with the vent pointed vertically down, see Figure 2. if the vent cannot be installed in a vertically down position, the regulator must be installed under a separate protective cover. Installing the regulator with the vent down allows condensation to drain, minimizes the entry of water or other debris from entering the vent, and minimizes vent blockage from freezing precipitation. Do not install the regulator in a location where there can be excessive water accumulation or ice formation, such as directly beneath a down spout, gutter, or roof line of building. Even a protective hood may not provide adequate protection in these instances. Install the regulator so that any gas discharge through the vent or vent assembly is over 3 feet (0,91' meters) horizontally from any buiiding opening below the level of discharge. Install the regulator high enough above ground level at least 18-inches (45 cm) - so that rain splatter cannot freeze in the vent. P,ogUI',�1t®r§'SulS1ect,e .o Kdavy Snow Conditions Some installations, such as in areas with heavy snowfall, may require a hood or enclosure to protect the regulator from snow load and vent freeze over. Horizontally Installed Regulators Horizontally mounted regulators, such as found in single cylinder installations and ASME tanks, roust be installed beneath a protective cover or under the ASME tank dome, refer to Figure 3. If possible, slope or turn the vent down sufficiently to allow any condensation to drain out of the spring case„ Be careful that the slot in the tank donne or protective cover for the regulator's outlet piping does not expose the vent to the elements. The first stage vent on the Type R632 should be pointed down. Deter installations Type R642 regulators have an angle body that makes it easy to install on to a gas meter instead of piping leading directly into a building. Meter and Type R642 with vent over regulator inlet: Install the regulator per instructions given in the previous section "Installation Location". ri, R 00 and H RL Series LP -Gas Regulator's Figure 3. Tank Installation Meter and Type R642 with vent over the regulator outlet and install6d over the top of the meter. This installation orientation will put the Type R642 regulator vent in a vertical down position, but very close to the top of the gas meter. The regulator vent may become blocked during a freezing rain storm or heavy sndws. Therefore, some type of protective cover -should be installed over the regulator and meter or vent piping should be installed so that the vent remains open. Meter and Type k642 Regulator installed Indoors: Pipe the regulator vent per the section "Indoor Installations". indoor Dnstalladons By code, regulators installed indoors have limited inlet pressure, and they require a vent line to the outside of the building, see Figure 4. A vent assembly, such as Fisher Y602 Series, should be used on the end of the vent line. The same installation precautions, previously discussed throughout this manual for the regulator vent, apply to the end of the vent tube assembly. Vent lines must not restrict: the gas flow from the regulator's internal relief valve. Vent lines should be at least 3/4-inch NPT pipe or 3/4-inch NPT size, Gray PVC Schedule 40 Rigid Nan -metallic Electrical Conduit for above Ground. Service; per Ui_ 651'. To install the vent line, remove the vent screen and apply a good grade of pipe dope to the male threads of the line. Vent lines should he as straight as possible with a minimum number of bends.

THEN CORRECT INSTALLATION. Figure 5. Underground Installation Underground Installations L 1UTlON� Type R632 integral regulators require 2 vent tubes, one on the first stage vent and one on the second stage vent, when installed on underground tanks. Failure to use 2 separate vent tubes can result in early regulator failure and/or over pressuring the second stage that could result in fires or personal injury. Regulators installed in the dome of an underground container require a vent tube to prevent water from entering the regulator spring case, see Figure 5. Note: Type R632 integral regulators installed on underground tanks require the use of 2 vent tubes, one for the first stage vent and the other for the second stage vent of the regulator. Remove the vent screen and install a vent tube. .-The vent tube must be run from the regulator vent to above, the maximum water table. The vent tube opening must terminate at the extreme top inside of the dome cover. Make sure the regulator's closing cap is on tightly, and maintain drainage away from the dome at all times. For further information on Underground Installations, contact Aero Fulfillment Services at phone number 866-840-1075 and ask for Item number 000412 "Installation of Underground LP -Gas Systems: Suggested Installation, Inspection,". Adjustment Each regulator is factory set. if it becomes necessary to increase the outlet pressure, remove the closing cap and turn the adjustment screw clockwise. Turn the adjusting screw counterclockwise to decrease the outlet pressure. The first stage portion of the Type R632 integral regulator is non-adjustable. The outlet pressure plug may be removed using a W16-inch (11,1 mm) hexagon wrench. The pressure tap is restricted, so the plug can be removed with pressure on the outlet of the regulator. Install a pressure gauge to determine the regulator's outlet setting during adjustment, (Actual pressure at the second stage regulator may be less due to line loss.) After setting, reinstall the pipe plug and replace the closing cap. Check the plug for leakage. Inlet pressure may be chocked using the inlet pressure gauge tap and a pressure gauge. Remove the plug using a 7116-inch (11,1 mm) wrench. The pressure tap is restricted, so the plug can be r-eMoved with pressure on the inlet of the regulator. overpressure ProtecUon y. some type of overpressure protection is needed if actual inlet pressure can exceed the outlet pressure rating. Overpressuring any portion of this equipment above the LP-Gasr600 and HSRL Series Regulators limits shown in the Specifications section 'ram' may cause damage to regulator parts, leaks in the regulator, or personal injury due to bursting of pressure -containing parts or explosion of accumulated gas. if any portion of the regulator is exposed to an overpressure condition that exceeds the limits in the Specifications section, it roust be inspected for damage that may have occurred. Large volumes of gas may discharge through the regulator vent during internal relief valve operation, which can, if not coritro[ied, result in fire or explosion from accumulated gas. J,3 The R600 and HSRI_ Series regulators, except for the first stage of the 'Type R632, contain internal relief valves. The internal relief valve in all units -will give overpressure protection against excessive build-up resulting from seat leakage due to worn parts or chips or foreign material on the orifice. The amount of internal relief protection provided varies with the regulator type and the cause for the overpressure relief valve operation. When the internal relief valve opens, gas escapes to the atmosphere through the regulator's vent. Sonie type of additional sxterrial overpressure protection must be provided if the outlet pressure in an overpressure condition exceeds the inlet pressure rating of the gas system or downstream equipment. Common methods of external overpressure protection include relief valves, monitoring regulators, shutoff devices, and series regulation. Maintenance To avoid personal injury or equipment damage, do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure. Regulators that have been disassembled for repair must be tested for proper operation before being returned to service Only parts manufactured by Fisher should be used for repairing Fisher regulators. Relight pilot lights according to normal startup procedures. Due to normal wear or damage that may occur from external sources, these regulator's must be inspected and maintained periodically. The frequency of inspection and replacement of the regulators depends upon the severity of service conditions or the requirements of local, state, and federal regulations. Even under ideal conditions, these regulators should be replaced after 20 years from date of manufacture or sooner should inspection reveal the need. Visually inspect the regulator each time a gas delivery is made for: Improper installation, vent not pointed vertically down or under a cover; no vent tube on underground systems. Plugged or frozen vent. Wrong regulator or no regulator in the systom. o Internal or external corrosion. Flooded Regulator; water in spring case; regulator submersed on underground tanks Regulator age. Any other condition that could cause th.eun.controlled escape of gas. Failure to do the above could result in personal injury or property damage. Vert Opening Make sure the regulator vent, vent assembly, or vent tube does not become plugged by mud, insects, ice, snow, paint, etc. The vent screen aids in keeping the vent from becoming plugged, and the screen should be clean and properly installed. Water inside Regulators from Floods, Weather or Water Table on Underground Systems Replace any regulator that has been flooded or has been submersed below the water table of an underground tank, have had water in their spring case or show evidence of external or internal corrosion. Checking for internal corrosion can be done by removing the closing cap and with the aid of a flashlight observing the condition of the reilef valve spring, main spring, and internal spring barrel area, A more detailed examination will require shutting down of the gas system and the complete removal of the adjusting screw. Closely examine regulators installed with their vent horizontal for signs of corrosion. Correct any improper installations, Regulator Replacement Older regulators are more likely to catastrophically fail because of worn or corroded parts. Replace R600 and 1-ISRL Series regulators over 20 years of age.' Other service or environmental conditions. may dictate replacement of the regulator before it becomes 20 years old. Regulators that are installed on underground systems and in areas that are subject to sea salt (coastal) atmospheres should be inspected annually for external and internal corrosion and may require replacement sooner. Refer to Fisher Bulletin L.P-32 for additional information. Regulator Repair Regulators that have been disassembled for repair must be tested for proper operation before being returned to service. Only parts manufactured by Fisher should be used to repair Fisher regulators. Be sure to give the complete type number of the regulator when corresponding with the factory. The type number, orifice size, and spring range are on a label attached to the spring barrel. The date of manufacture is stamped on the regulator. Always provide this information in any correspondence with your Fisher Distributor regarding replacement parts or technical assistance, 'If cons-tructl6n changes are made in the field, he sere that the.regulator marking is also changed to reflect the most recent construction.
