Never use them on low pressure (inches of water column) service because personal injury or property damage could occur. Before installation: • Check for damage, which may have occurred in shipment. • Check for and remove any dirt or foreign material that may have accumulated in the regulator body. • 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 ofthe 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, see Figure 2: • 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. Ifthe vent cannot be installed in a vertically down position, the regulator must be installed under a separate protective cover. Installingthe 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 protective hood may not provide adequate protection in these instances. • Install the regulator so that any gas discharge though the vent or vent assembly is over -feet (0,9 meters) horizontally from any building opening below the level of discharge and not less than 5- feet in any direction away from any source of ignition, openings into direct vent appliances, or mechanical ventilation air intakes. • Install the regulator high enough above ground level -atleast 24- inches (60 cm) -so that rain splatter cannot freeze in the vent • 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. '.flRiriX 1636ni Maar mtee U.S.A Horizontally Installed Regulators, see Figure 3: Horizontally mounted regulators, such as found in single cylinder installations and ASME tanks, must be installed beneath a protective cover or underthe ASME tank dome. 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 regulator's outlet piping does not expose the vent to the elements. The first stage vent on the integral two -stage regulator should be pointed down. fROA :STAG `-f79ura d; 4s6meaf Imholhailen:, Indoor Installations, see Figure 4: The first stage and integral regulators are not recommended for indoor installations. The second stage regulator may be installed indoors as follows. - By code, regulators installed indoors have limited inlet pressure, and they require a vent line to the outside of the building. A vent assembly, such as MEC ME960 or at least 314" NPT pipe, Gray PVC Schedule 40 Rigid Non - Metallic Electrical Conduit for above Ground Service, per UL 651, should be used. 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. To install the vent line, remove the vent screen and apply a good grade of pipe compound to the male threads of the line. Vent lines should be as straight as possible with a minimum number of bends. }'a�ma�aG1°".m.e0° iavas�i'.�ut, t'im-some 11'—'-- . u araAL'am wcownaae. ".rvcwevrrrxroa.a.� - wawnnxa+ TILL—,, J. - i1pv- ,Undergoround Whidlnflish Underground Installations, we Figure 5: The Integral two -stage regulators require 2 vent lines, one for the flat stage vent (1/4" OD copper tube Inverted flare connection: 7/16-24 UN thread) and the other for the sewnd stage vent (3/9" NPT) of the regulator. Failure to use 2 separate vent tubes can result in early regulator failure and / or over pressuring the second stage that could result in fire or personal injury. N. r a MEGR-1100, 1200 AND 1600 SERIES A regulator installed in the dome of an underground container requires a vent line to prevent water from entering the regulator spring use. Remove the vent screen(s) and install a vent line(s). The vent line must be run from the regulator vent(s) to above the maximum water table. The vent line opening(s) must terminate at the extreme top inside of the dome cover. Make sure the regulator's closing up is on tightly, and maintain drainage away from the dome at all times. 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 inlet and outlet pressure tap plugs may be removed using a 7/16" wrench. The pressure tap is restricted with a #54 onfice, so the plug can be removed with pressure in the regulator. Install a pressure gauge to determine the regulator's inlet pressure and outlet setting during adjustment. Actual pressure at the second stage regulator may be less due to line loss. After setting, add thread sealant to the pipe plug and reinstall it. Replace the closing cap. Check the plug for leakage. Overpressure Protection Same type of overpressure protection is needed if actual inlet pressure can exceed the inlet pressure rating. Overpressuring any portion of this equipment above the limits shown in the Specifications 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, it must be inspected for damage that may have occurred. Large volumes of gas may discharge though the regulator vent during internal relief valve operation, which can, if not controlled, result in fire or explosion from accumulated gas. The first stage, integral two -stage, and second stage series regulator, except for the first stage of the integral two -stage, 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, 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. Same type of additional external 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 MEC should be used for repairing MEC regulators. Relight pilot lights according to normal startup procedures found In the appliance manufacturers' instructions. 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 25 years from date of manufacture or sooner should inspection reveal the need. Visually inspect the regulatoreach time a gas delivery is made for. • Improper installation; such as vent not pointed vertimlly, down or under a cover, no vent line on underground systems • Plugged orfrozen vent • Wrong regulator or no regulator in the system • External corrosion • Flooded Regulator; water in spring use, regulator submersed on underground ranks • Regulatorage • Any other condition that could muse the uncontrolled escape of gas Failure to do the above could result in personal injury or property damage. Vent Opening Make sure the regulator vent, vent assembly, or vent line does not become plugged by mud, insects, ice, snow, paint, etc. Theverltscreen aids in keeping the vent from becoming plugged; the screen should be dean 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, has water in the spring case or shows evidence of external or internal corrosion. Checking for internal corrosion on the first stage and integral two -stage of the second stage portion, can be done by removing the closing up and with the aid of a flashlight observing the condition 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 second stage 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 fail catastrophically bemuse of worn or corroded parts. Replace all regulators over 25 years of age. Other service or environmental conditions may dictate replacement of the regulator before the end of its 25 year service life. 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. Regulator Repair Only personnel trained in the proper procedures, codes, standards and regulations of the LP -Gas industry shall hsmll and service this equipment. Regulators that have been disassembled for repair must be tested for proper operation before being returned to service. Only parts manufactured by MEC should be used to repair MEC regulators. Besure W give the complete Part Number of the regulator when corresponding with the factory. The part 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 MEC Distributor regarding replacement parts or technical assistance. If construction changes are made in the field, be sure that the regulator marking is also changed to reflect the most recent construction.

Why Tanks Corrode Underground steel tanks corrode due to an electrochemical reaction between the tank and the surrounding soil. The process of corrosion occurs due to small voltage differences on the steel surface that result in the flow of DC current from one location to another. Where current flows from the tank into the soil corrosion occurs. This location is called the anode in a corrosion circuit. Where current flows from the soil to the tank, no corrosion occurs. The progress of corrosion is detennined by the amount of current flowing between the anode and the cathode and whether the locations of the anode/ cathode remain constant over time. Corrosion rates are generally higher in wet soil environments since the conductivity of the soil promotes the flow of DC current in the corrosion circuit. Corrosion generally exhibits itself on underground tanks in either a general overall rusting or more commonly, a pitting attack. Pit locations may result from metallurgical conditions of the steel surface or soil variations such as rocks, salts, fertilizer, moisture concentration, oxygen concentration, etc. Preventing Corrosion Protecting underground tanks from corrosion is easily achieved by the use of two commonly applied protection methods: external coating and cathodic protection. These two methods are complementary and should be used in conjunction with the other. An effective external protective coating insulates the steel from the soil environment, thus preventing the flow of corrosion current from the anode to the cathode. An effective external coating can protect over 99% of the tank surface area. However, no coating is perfect. Damage from construction or soil stresses create tiny defects, which may result in accelerated corrosion at the defect. Cathodic protection prevents corrosion at those defects by applying DC current from an external source, forcing the tank to become cathode. Application of sufficient DC current to the tank will prevent any corrosion from occurring. The two general types of cathodic protection systems are sacrificial and impressed current Sacrificial systems are used when the amount of current required for the protection is small, such as in underground propane tanks. Impressed current systems are more commonly used for large structures such as large diameter pipelines. Electrical isolation of the tank from metallic piping systems and electrical grounds is critical for the cathodic protection system's effectiveness. How Sacrificial Cathodic Protection Works Sacrificial systems work by creating a galvanic connection between two different metals. The most common anode material is magnesium, which when coupled to steel results in DC current flow from the magnesium to the steel. The open circuit potential of steel is about -0.50 volts referenced to a copper sulfate electrode. The open circuit potential of magnesium is about -1.55V to-1.80V. By connecting the two metals together, the difference of 1 to 1.25V volts results in current flow to the tank that overcomes the natural corrosion cells that exist on the tank. With this current available to the tank, no corrosion occurs. Magnesium Anodes There are a variety of anode sizes and alloys used for cathodic protection. The two primary alloys are designed as H-1 (or AZ63) and High Potential. The H-1 alloy is produced from recycled magnesium and has an open circuit potential of approximately—1.55V. This alloy is well suited for protection of underground propane tanks. The High Potential alloy is 99% pure magnesium having an open circuit potential up to -1.SV. This alloy should be used for soil applications over 10,000 ohm -cm resistivity. The two most common anode sizes used for underground propane tanks are 9lb. and 171b. The size designation relates to the metal weight. 10' of #12 TW insulated wire is attached to the anodes. Anodes are then backfilled in a mixture of gypsum, bentonite, and sodium sulfate to lower the electrical resistance of the anode to soil. The mixture is a low cost, nonhazardous, electrically conductive backfill. The anode and backfill is then packaged in a cotton bag and either a cardboard box or paper bag. Actual shipping weight of these anodes with backfill is 27 lb. and 45 lb. Application Recommendations Magnesium anodes can protect underground tanks in most soil conditions. The H-1 alloy is generally very effective. The following chart provides size and quantity recommendations forvarious size tanks based on conservative design assumptions. This chart covers soil conditions up to 10,000 ohm -centimeter resistivity. Resistivities higher than 10,000 ohm -centimeter generally represent very dry soils. Verification of soil resistivity can be performed through soil analysis. Contact us for design recommendations in locations where soil resistivities exceed 10,000 ohm -cm, or if there is no effective external coating on the tank The propane service line from the tank to the house also must be considered in the cathodic protection design, unless the service line is plastic. All underground steel pipe should be externally coated with a corrosion resistant material. The service line should be electrically isolated at the house with an insulating fitting or union. If service pipe is less than 50' in length, the tank anodes will provide sufficient current to protect both tank and pipe. For longer lengths of pipe, an additional anode may be required at the house connections. If another metallic material such as copper is used for service piping, the pipe should be electrically isolated from the tank at the fill pipe connection. Copper and steel create a galvanic couple thatwill accelerate corrosion of the steel tank when directly connected to copper piping. Generally, copper piping does not require cathodic protection. a----- - - IF Soil Type Fertile Sails, Clay, Sandy Loam Sand, Gravel, Rocky Areas Tank Cap.

Anode Installation 1. Determine size and quantity of anodes from application chart. 2. When a single anode is installed, it should be located near the tank center on either side of tank. 3.When multiple anodes are installed, space them evenly around the tank. See examples below. 1 anode: Z'anodis 4 anodes 0 0 o 4.Anodes are shipped in either cardboard boxes or multi -wall papersacks. Remove outer container and burythe cloth bagged anode. If anode is supplied in plastic bag, remove plastic bag before installing. 5. Install anodes approximately two to three feet from the tank and at least as deep as the center line of the tank. Anodes work best in locations with permanent moisture, so generally the deeper the better. 6.After placing the anode, stretch out the anode connection wire and extend over to a connection point on the tank fill pipe. 7.Cover the anode with approximately six inches of backfill and pour 5 gallons of water on the anode to saturate the prepared backfill. Water is necessary to activate the anode. 8.Connect the anode wire to the tank with a low electrical resistance connection. Examples are threaded stud on the tank fill pipe or any accessible metallic connection point to the tank. All connections should be coated with a moisture -proof material. 9.Ideally, the tank connection is made in the area of the tank fill pipe within the covered dome. With access to the anode wire, subsequent testing of the tank can include measurement of anode output and verification of performance. 10.Verify performance of the anode using an appropriate test procedure. Mechanical Connection Under Dome Cathodic Protection Testing Procedure Equipment Needed: Digital Voltmeter, Red Test Lead Min.12' Long & Black Lead Min. 2' Long, Reference Electrode (Copper/Copper Sulphate Half -Cell) STEP 1: Using a digital voltmeter insert the red test lead into the Volt lack of the meter and select the 2 or 20 volt DC scale. Clip red test lead connector to an uncoated metallic area of the tank, preferably to the fill pipe multivalve. A good solid connection is very important. (DO NOT connect to shroud). STEP 2: Insertthe blacktest lead into the Common jack on the meter, and connect the opposite end of the lead to a charged reference electrode (Ye cell). STEP 3: Remove protective cap from the porous plug at bottom end of electrode. Place porous plug end into native soil (remove grass if necessary) at four locations around the tank (one on each side of the tank, and one at each end of the tank). If difficulty is encountered obtaining readings, moisten soil with water or dig Ye cell deeper into the soil. STEP 4: Record all four meter readings on an appropriate form. The least of all four readings should be a minimum of-0.850v or more negative. (Note: If any of the four readings are below (less negative) -0.850v then the tank is not fully protected}. Charging Reference Electrode STEP 1: Unscrew and remove porous plug end of new reference electrode. Add deionized or distilled water to the copper sulfate crystals, filling electrode completely. The solution will turn blue in color and there should always be excess crystals at the bottom of the tube. DO NOT USE TAP WATER. STEP 2: Replace porous plug end of electrode and place in an upright position so that the porous plug end is facing in the down position and let stand for 1 hour before use. This will allow the porous plug to become completely saturated before use. Caution: Do not allow electrode to contact all, road salts, or other substances that may contaminate the solution by absorption through porous plug- Do not allow electrode to freeze.
