Installation (Continued)
The first stage and Integral two -stage regulators are not suitable
for indoor installations. 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 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.

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 3/4" 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 forthe 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.

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. '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 cambe
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 inthese
instances.
• Install the regulator so that any gas discharge though the vent or
vent assembly is over 3 -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 - at least 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.
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 under the 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.

Underground Installations, see Figure 5:
The integral two -stage regulators require 2 vent lines, one for
the first stage vent (1/4" OD copper tube inverted flare
connection: 7/16-24 UN thread) and the other for the second
stage vent (3/8" 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.
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 case.
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 cap 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 4754 orifice, 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
Some 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.
Some 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 regulator each time a gas delivery is made for:
• Improper installation; such as vent not pointed vertically down or
under a cover, no vent line on underground systems
• Plugged or frozen vent
• Wrong regulator or no regulator in the system
• External corrosion
• Flooded Regulator; water in spring case, regulator submersed on
underground tanks
• Regulator age
• Any other condition that could cause 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. The vent screen
aids in keeping the vent from becoming plugged; 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, 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 cap 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 because 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 install 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. Be sure
to 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 determined 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 bythe 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 tfiose 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 -1.8V. 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 9 lb. 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 that will accelerate
corrosion of the steel tank when directly connected to copper piping.
Generally, copper piping does not require cathodic protection.

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, 2 anrifes 4and es
4.Anodes are shipped in either cardboard boxes or multi -wall
paper sacks. Remove outer container and bury the 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
jack 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: Insert the black test lead into the Common jack on the meter,
and connect the opposite end of the lead to a charged reference
electrode (1/2 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 %z 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 oil, road salts, or other
substances that may contaminate the solution by absorption
through porous plug. Do not allow electrode to freeze.
