Tank Installation approximately 10 psig / 0.69 bar or 5 psig 10.35 bar Inlet General Installation Instructions pressure to a second stage regulator. On final stage service Before installing the regulator, the regulator reduces container pressure for a high pressure burner. The regulator is painted RED. Check for damage, which might have occurred In shipment. Installation WARNING All vents should be kept open to permit free flow of air In and out of the regulator. Protect vent openings against the entrance of rain, snow, Ice formation, paint, mud, Insects, waterfrom an irrigation system or any other foreign material that could plug the vent or vent line or accumulate in the vent line. LP -Gas may discharge to the atmosphere through the vent. An obstructed vent which limits air or gas flow can cause abnormally high pressure that could result In personal Injury or property damage. The Types R232A, R232E, R122H and R222H are not suitable for Indoor Installations. Failure to use a vent line with Type R222 second stage regulators in indoor applications can cause a hazardous accumulation of gas which could result In personal injury or property damage. Never use the Types R1122H, R222H and • Check for and remove any dirt or foreign material, which may have accumulated in the regulatorbody. • Replace old pigtails. Blow out any debris, dirt or copper sulfate in the copper tubing and the pipeline. • 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. "Inler and °Outlet' connections are clearly marked, Installation Location • The installed regulator should be 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 low pressure (inches of water column) such as directly beneath down spout, gutter or roof service because personal Injury or property line of building, Even a protective hood may not provide damage could occur. adequate protection In these instances. _122H, R222H, R222, R2'Z' and R232E Series LP -Gas Regulators TOAPPLULNCE VENT LINE BASEMENT VENT OPENING MUSTBE ATLEASTSFT./O.Sm HORIZONTALLY FROM ANY BUILDING OPENING BELOW IT FROMFIRSTSTAGE f l� REGULATOR GRADE GROUND DOWNWARD AND SLOPING AWAY FROM HOUSING DOME.

Regulators Subjected to Heavy Snow Conditions Some installations, such as in areas with heavy snowfall, may require a hood or enclosure to protect the regulator from snow toad and vent freeze over. Horizontally Installed Regulators Horizontally mounted regulators, such as found in single cylinder installations and ASME tanks, must 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 dome or protective cover for the regulators outlet piping does not expose the vent to the elements. The first stage vent on the Types R232A and R232E should be pointed down. Indoor Installations The Types R122H, R222H, R232A and.R232E regulators are not recommended for indoor installations. The Type R222 regulator may be installedindoors as follows. 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 Fishere Y602 Series, should be used on the and 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 in. NPT pipe or 3/4 in. NPT size, Gray PVC Schedule 40 Rigid Non-metallic Electrical Conduit for above Ground Service, per UL® 851. 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 be as straight as possible with a minimum number of bends. Underground Installations WARNING types KzbZA ana R232E Integral regulators require 2 vent tubes, one on the first stage vent and one on the second stage vent, when Installed on underground tanks. UL•fa a mark awnad by undanwka , LabomranaL. Failure to use 2separate venttubes can result In early regulator failure and/or over pressuring the second stage that could result in fires or personal Injury. A regulator installed In the dome of an underground container requires a vent tube to prevent water from entering the regulator spring case, see Figure 5. The Types R122H and R222H will require one vent line and if the Types R232A and R232E integral regulators is installed on an underground tank the use of 2 vent tubes are required, one for the first stage vent (1/4 in. OD copper tube inverted flare connection: 7/16-24 UN thread) and the otherfor the second stage vent (3/8 NPT) of the regulator, are required. Remove the vent screen(s) and install vent tube(s). The vent tube must be run from the regulator vent(s) to above the maximum water table. The vent tube opening(s) must terminate at the extreme top inside of the dome cover. Make sure the regulator's dosing cap Is on tightly and maintain drainage away from the dome at all times. Outdoor Installations with Underground Vent Lines When installed per code, the underground vent line must not restrict the gas flow from the regulator's internal relief valve and must remain clear of debris, dry and fully open at all times. Joints in the vent line must be fully sealed to prevent moisture Intrusion into the vent line. A vent assembly, sUd7 as the Fisher Y602 Series, should be used on the end of the vent line to prevent entry of precipitation, water or other debris.

Replace the dosing cap. Check the plug for leakage. 22H, R222H, R222, R23' and R232E Series IP-Gas Regulators Overpressure Protection WARNING 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 limits shown in the Specifications may cause damage to regulator parts, leaks In the regulatoror 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, it must 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 controlled, result In fire or explosion from accumulated gas. The R122H, R222H, R222, R232A and R232E Series regulators, except for the fast stage of the Types R232A and R232E, 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 wom parts or chips or foreign material on the critics. The amount: of Internal relief protection provided varies with the regulator type and the cause for the overpressure relief valve operation, see Table 1. When the Internal relief valve opens, gas escapes to the atmosphere through the regulators vent. Some type of additional external overpressure Protection must be provided if the outlet pressure in an overpressure condition exceeds the Intel 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 W WARNING To avoid personal Injury or equipment damage, do not attempt any maintenance 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 regulators 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 soone►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 system • Internal or external corrosion, Including paint chipping or flaking • Flooded Regulator; water in spring case; regulator submersed on underground tanks • Regulator age' • Any other condition that could causoaa+amatrallerh escape of gas Failure to do the above could result in personal injury or property damage. Vent Opening Make sure the regulator vent, vent asaemblxpssrefll tube does not become plugged by mud, insedts, ic`e, snow, paint, etc. The vent screen aids in keeping the vent from becoming plugged and the screen should be clean and property installed. Make sure any Irrigation system operated near a regulator or vent line does not spray water into the vent opening of the regulator or vent assembly. Water inside Regulators from Floods, Weather or Water Table on Underground Systems Kepiace any regulator that had water in their spring case, has been flooded, has been submersed below the water table of an underground tank or shows evidence of external or Internal corrosion. Checking for Internal R122H, R22r,_,r R222, R232A and R232E _caries LP -Gas Regulators corrosion on the Type R222HiR222 and the second stage portions of the Types R232A and R232E can be done by removing the closing cap and with the aid of a flashlight observing the oor)dition of the relief valve spring, main spring and internal spring barrel area. A more detailed examination will require shutting down the gas system and the complete removal of the adjusting screw. The Type R122H regulator must be completely disassembled by a qualified person to look for internal corrosion. 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 R122H, R222H, R222, R232A and R232E 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 In corrosive environments Including but not limited to the following conditions should be inspected annually for visual indication of external or internal corrosion and paint chipping or flaking.

Any outiet pressure above the'start-todischarge point of the nonadjustable relief valve spring moves the diaphragm off the reliefvalve`seat, allowing excess pressure to bleed out through the screened spring case vent. Specifications The Specilloations section lists operating conditions and other specifications of the Type R622 regulator. Information specific to a regulator's construction is stamped on the nameplate. Principle of Operation* Referto Figure 2. When downstream demand decreases, the pressure under the diaphragm Increases. This pressure overcomes the regulator setting (which is set by a spring). Through the action of the pusher.post assembly, lever, and valve stem, . the valve disk moves closer to the orifice and reduces under the diaphragm decreases. Spring force pushes the pusher post assembly downward and the valve disk moves away from the orifice. Type; R622 regulators include an Inte4al relief valve used to help minimize overpressure. An I utlef pressure above the start -to -discharge pointof the non-adjustable relief spring moves (fie diaphragm off of the relief seat, allowing excess pressurp to discharge through the vent. installation I WARNING Personal injury, equ€pinentdamage, or leakage due to escaping gas or bursting of Pressure -containing parts might result if these regulators are overpressured or installed where service conditions could exceed the limits for which the regulators were designed, or where conditions exceed any ratings of the adjacent piping or piping connections. To avoid such Injury or damage, provide pressure• relieving or Pressure -limiting devices (as required by the appropriate code, service conditions from exceeding those limits. Additionally, physical dmage to a regulator could cause p sonal injury and property damage dit to escaping gas. To avoid such injury and damage, Install the regulator in a safe location. Aregulator may vent some gas to the atmosphere in hazardous or flammable gas service, vented gas might accumulate and cause personal -injury, death or property damage due to fire or explosion. Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous location. The vent line must be protected against condensation or clogging. Before installing the regulator, check for damage which might have occurred In shipment. Also check for dirt or foreign matter which may have accumulated In the regulator body or In the pipeflne. Apply pipe compound to the external threads of the pipeline and Install the regulator so that the flow is in the direction of the arrow cast on the side of the body. The diaphragm actuator assembly can be rotated to any positionre►ative to the body, In 90° increments. Do not install the regulator in a location where there can be excessive water accumulation, such as directly beneath a downspout or in an undrained pit To obtain the maidmum flow capacities or other performance characteristics, the length ofpipe from the regulator outlet to the meter --or for the first 18•inches (457 mmj, whlcheirer is closer —should have no bends and should be the same size as the:regdlator outlet. Replace the regulator if water gets into the spring case or the lower casing of the regulator. Type R622 regulators have a spring case vent (314 NPT) which is screened to prevent insects or foreign material from entering. You are advised to use new vent piping becausedefective threads on the relief vent piping may interfere with the venting assembly if the piping obstructs the movement of the vent flapper. On indoor Installations, the vent should be piped outside the building, see Figure 3. Remove the screen from the regulator vent connection and connect vent piping from that connection to the outdoors. Vent piping should be as large in diameter as practical. be of bends and elbows. Install a weather and insect resistant vent assembly on the outside end of the pipe, such as a Type Ye02.

A program of regular Inspection bf the vent opening should be established to see that it has not become plugged by foreign material. On some instailations, such as In areas of heavy snowfall, it maybe necessary to Install the regulator beneath a protective hoods If other protection is provided from the elements, the vent should be pointing or sloping down suffidently to allow any condensate to drain. Also check the regulator perfodicagyfor external or irdernal.corrosion. Overpressure Protection CAI WARNING Some type croverpressure protection Is needed if actual inlet pressure can exceed the outtetpressure rating.

Regulators should be inspected fordamage after arty overpressuke condition. Twe R622 To avoid personal injury or property damage due to explosion or damage to regulator or downstream components during startup; release downstream pressure to prevent an overpressure condition on the diaphragm of the regulator. In order to avoid an overpressure condition and possible equipment damage, pressure gauges should always be used to monitor pressures during startup. 1. Check fo see that all appliances are turned off. 2. Slowly open the upstream shutoff valve. 3. Slowly open the•downstream shumff valve 4. Check all connections for leaks. 5. Make final control spring a ,W�egor,�jng to the adjustment procedures S. Light the appliance pilots. Adjustment pSL G• DEPT. To increase the outlet press sap tRawlWy the adjusting screw (key 4 n $) must be turned clockwise. This requires removal of the closing cap . (key 31, Figure 5). To reduce the outlet pressure setting, turn the adjusting screw counterclockwise.' Apressure gauge should always be used to mohitor downstream pressure while adjustments are being made. Do not adjustihe spring to produce an outlet pressure setting above the limit identified on the Information label. If the required pressure setting is not within the range of the spring being used, substitute with the correct spring, see Table 1. When changing the spring, also change the range identified on the Information label to indicate the actual pressure range of the spring in use. After the spring adjustment has been completed, replace the dosing cap. WARNING damage due to explosion or damage to regulator or downstream components during shutdown, release downstream pressure to prevent an overpressure condition on the regulator diaphragm. . 6 Installation arrangements may vary, but in any installation it is important that the valves be opened or closed slowly. These steps apply to the typical installation. 1. Slowly Close the downstream shutoff valve. 2. Slowly close the upstream shutoff valve. 3. Open vent valves downstream of the regulator. 4. Open ventvalves upstream of the regulator. Maintenance Avoid personal injury or damage to property from sudden release of pressure or uncontrolled gas or other process fluid. Before starting to disassemble, Isolate the regulator from all pressure and cauflously release trapped pressure from the regulator. Use gauges to monitor Inlet loading and outlet pressures while releasing these pressures. These procedures are for gaining access to the diaphragm, valve disk and critics. All pressure must be released from the diaphragm actuator assembly before the following steps can, be performed. While using the following procedures, refer to Figure 5 for key number locations.
