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 tows 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 Pitlocations
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
Wks from corrosion is
easilyachfeved bythe use
oftwo commonlyapplied
protection . methods:
external coaling 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%ofthe tanksurfacearea. However;
no coaling is perfect Damage from construction orsofl 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 cumentto the tank011 preventany
corrosion from occurring. The two general types of cathodic pratectfon
systems are sacrfficfal 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. FJechical isolation of the flank from metallic piping systems
and electrical grounds is critical for the cathodic protection system's
effectiveness.
Now 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 1.25Vvofts results in current
flowta the tnkthat 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 (orAZ63) 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 saes used for underground propane
tanks are 9lb. and 171b. The size designation relates to the metal weight
10' of 112 TIN insulated wire is attached to the anodes. Anodes are
then bacldilled in a mixture of gypsum, bentordte, and sodium sulfate
to lower the electrical resistance of the anode to soil. The mbdure is a
low cost, nonhazardous, electrically conductive backfill. The anode and
backfill is then packaged Ina cotton bag and either a cardboard box or
paper bag. Actual shipping weight of these anodes with backfill is 27
lb. and 451b.
Application Recommendations
Magnesium anodes can protect underground tanks in most soil
conditions. The H-1 alloy is generally veryeffective. The following chart
provides size and quani tyrecommendations forvarioussize tanks based
on conservative design assumptions. This chart covers soil conditions
up to 10,000 ohm -centimeter resistivity. Resisiivfies 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 resistivitias exceed
10,000 ohm -cm, or it 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 Win 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 he electrically isolated from the tank at the fill pipe
connection. Copperand steel create a galvanic couplethatwill accelerate
corrosion of the steel tank when directly connected to cropper 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 3 anodes 4.anodes
4.Anodes are shipped In efther cardboard boxes or multi -wall
papersacks. 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 tankand
at leastas deep as the center line of the tank. Anodesworkbest
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.
B.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 paint 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.Vedfy performance of the anode using an appropriate test
procedure.
Mechanical Connection Under Horne
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 volimeterinsertthe 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 thefill pipe multivalve. A good solid connection is very important.
(DO NOT connect to shroud).
STEP 2• Insertthe black test lead into the Common jack on the meter,
and connect the opposite end of the lead to a charged reference
electrode (Yz 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 and of the tank). If difficulty is encountered
obtaining readings, moisten soil with water or dig 31 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 ofthe 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 defonized 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 and 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.
Cautlon: Do not alloweleetrode to eonhael off, road salts, arother
substances that may eardamfnate the sofutlon by • ahsarpUon
through pomus plug. Da flat allow electrode to freeze -

Loss of Pressure
Freeze-up inside the regulator.
This will prevent the regulator from regulating properly.
Regulator freeze -ups occur because there is excessive moisture
in the gas. Fraeze-ups can also occur in pigtals that are kinked or
bent where free flow of the LP -Gas is restricted. These freeze -ups
can occur when the moisture, gas now and temperature combine to
create a hazardous condition. Freeze -ups can occur at temperatures
above 37F.
Action Required: Ali LP -Gas should be checked for moisture content
prior to delivery to consumers and proper amounts of anhydrous
methanol added if the gas cannot be returned to the supplier. Any
container suspected of having excessive moisture should be treated
with the proper amount of methanol.
Customer safety
Since regulators are often used by consumers without previous
knowledge of the hazards of LP -Gas, and the LP -Gas dealers are the
only ones who have direct contact with the consumers,
It Is the dealer's responsibiilty to make sure that his
customers are property fnstrircted in safety matters relating
to their installation.
At the very minimum, it is desirable that these customers:
1. Know the odor of LP -Gas and what to do in case they smell
gas. Use the NPGA "Scratch 'n Snfifu leaflet.
2 Are instructed to never tamper with the system.
3, Know that when protective hoods are used to enclose
regulators and/or valves, that these hoods must be closed,
but not locked.
4. Keep snow drifts from covering regulators.
5. Know the location of the cylinder or tank shut-off valve in
emergencies.
Underground installatigns
Special hazards can occur if regulators are not properly installed in
underground systems. Water, dirt, mud and insects can get into the
regulator if the bonnet cap is not tightly in place and the vent is not
protected with a proper vent tube, opening above any potential water
level.
Most problems occur because the waterproof dome on the buried
storage tank does not extend above the ground level sufficiently to
keep out water and mud.
Refer to NPGA No. 401.

General Warning
All RegO Products are mechanical devices thatwill eventually
become Inoperative due to wear, contaminants, corrosion
and aging of components made of materials such as metal
and rubber. As a general recommendation,Regulators should
be replaced in accordance with all of the recommendations
outlined in this safety warning. The recommended service
life of a regulator is one of many factors -that must be
considered in determining when to replace a regulator.
The environment and conditions or use will eerermme me sate
service life of these products. Periodic inspection and maintenance
are essential.
Because RegO Products have a long and proven record of quefny
and service, IP-Gas Healers may forget the hazards that can occur
because a regulator is used beyond its safe service life. Life of a
regulator Is determined by the environment in which it gives." The
LP -Gas dealer knows better than anyone what this environment Is.
NOTE: There is a developing trend In state legislation and
in proposed national legislation to make the owners of l7roducts
responsible for replacing products before they reach the and of their
safe useful life. LP -Gas dealers should be aware of legislation which
could atfed them.

z 220 PSIG - and sill deliver a steady now of LP -Gas at 11" W.G.
mnsuming appliances. The regulator must deliver this pressure
opts a variable load from intermittent use of the appliances.
--�uoh a single -stage system may perform adequately in many
-; _.!lion, the use of a two -stage system offers the ultimate in pin-
�.t regulation. Two -stage regulation can result in a more profimble
was operation for the dealer resulting from less maintenance and
leer installation callbacks - and there Is no better time than raw for
'-stalling RegO Regulators in twostage systems.
JAtform Appliance Pressure
'?tr installation of a two -stage system - one high pressure regulator
zi tits container to compensate for varied Inlet pressures, and one
3w pressure regulator at the building to supply a constant delivery
;mssure to the appliances - helps ensure maximum efficiency
a-d trouble -free operation year-round. It is important to note that
w'ia pressure at the appliances can vary up to 4' w c. using singie-
slaae systems, two -stage systems keep pressure variations tvithin
f w.c. New high -efficiency appliances require this closer pressure
m-rhol for proper ignition and stable, efident operation. In fact, one
major manufacturer requires the use of two-siage systems with their
appliances.
Reduced Freeze-ups/Service Calls
>; Regulator freeze-up occurs when moisture in the gas condenses and
yes on cold surfaces of the regulator nozzle. The nozzle becomes
iw chilled when high pressure gas expands across it into the regulator
I;`. body. This chilling action is more severe in single -stage systems as
gas expands from tank pressure to I I' mc. through a single regulator
nozzle.
Size The System Correctly
Prior to installing your two -stage system, be sure the system pipe
and tubinb Is property sized. Proper sizing will help ensure constant
delivery pressure to the appliances during fluctuating loads at all
times. Just as Important be sure the Rego Regulators You choose
are capable of handling the desired bad. This is another advantage
of two -stage systems - they are capable of handling much
more BTU's/hr. than single -stage systems. The RegO "LP -Gas

rge Vent and

lie
Two -stage systems can greatly reduce the possibility of tieeze-ups
and resulting service calls as the expansion of gas from tank pressure
to it- w.c. is divided into two steps, with less chilling effect at each
regulator. In addition, after the gas exits the first -stage regulator and
enters the first -stage transmission line, it picks up heat from the line,
further reducing the possibility of second -stage freeze-up.
Service calls for pilot outages and electronic ignition system failures
are also reduced as a result of more uniform appliance pressure from
two-stsge systems.
Economy of Installation
In a sfnglo-stage system, transmission line piping between the
container and the appliances must be large enough to accommodate
the required volume of gas at 11" w.c. In contrast, the line between
the first and second stage regulators in lwo-stage systems can be
much smaller as it delivers gas at 10 PSIG to the second -stage
regulator. Often the savings in piping cost will pay for the second
regulator.
As an additional benefit, single -stage systems can be easily
converted to N,•o-slaga systems using existing supply lines when they
prove inadequate to meet added loads. This is the least expensive
and best method of correcting the problem.
Allowance for Future Appliances
A high degree of flexibility Is offered in new installations of two -
stage systems. Appliances can be added later to the present load -
provided the high pressure regulator can handle the Increase - by the
addition of a second low pressure regulator. Since appliances can be
regulated independently, demands from other parts of the installation
will not affect their individual performances.
Replace Pigtails
If you are replacing an old regulator, remember to replace the
copper pigtail. The old pk_lteii may contain corrosion which can
restrict now. In addition, corrosion may flake off and wedge
between the regulator orifice and seat disc - preventing proper
lock -up.

The Problem
Many modem LP -Gas appliances are equipped with plotless ignition
systems. Water heaters and older appliances use plot rights, but it
has become a common practice for energy conscious homeowners to
shut-off the pilot when leaving home for Wended periods of time. In
each instance, there is no gas demand at all forWanded periods.
The Consequences
If the first stage regulator fails to lock -up tight, usually as a result
of a wore seat disc or foreign material lodged between nozzle and
seat disc, pressure will build-up in the first stage piping — possibly
to a level that approaches tank pressure. Combining this with warm
ambient temperatures and cool ground, propane liquid may form In
the fast stage piping.
When gas demand resumes, this liquid may pass through the second
s!-ge ragul;tnr Into the appliances end filmace. NOTE-- the second
stage regulator Mil not relieve the pressure in first stage piping.
The rapid vaporization of the lqu!d may cause a rapid pressure surge
that could seriously damage critical components of the appliance and
furnace controls.
Afire or eVIosion could occur as a consequence.
The Solution
RegO LV4403 Series First Stage Regulators with Built -In Relief
Valves reduce the possibility of this serious hazard in hvo stage
applic awns. The built -In relief valve Is designed to vent as needed
and reduce the possibility of first stage piping pressure from
becoming high enough to form liquid.

AC Wire -in Combination
Carbon Monoxide & Smoke Alarm
- 120VAC Direct Wire with Battery Backup
- AlarmiVoice message warning system
- Intelligent Sensor Technology
Part Number 900-0114A Model KN-COSM-IBA
Description
The Kidde 900-0114A uses breakthrough technology to offer a fast
response to real fires, including smoldering and fast -flaming, as well as
protect you from carbon monoxide and dramatically reduce the chance of
nuisance alarms. The Intelligent sensor technology combines the detec-
tion capabilities of an ionization smoke sensor — which is more likely to
detect smaller, less visible fire particles, like those produced by flaming
fires — with that of an electrochemical sensor, which is used to detect
CO. Since carbon monoxide is present in all fires, having both detection
chambers work together in one alarm is a breakthrough in the fire safety
industry. When either sensor notices a potential hazard, it will communi-
cate with the other. Depending on what is detected, the alarm will adjust
its smoke sensitivity in order to better discriminate between a real hazard
and a false one. This constant communication enhances the alarm's over-
all performance in all fires, and significantly reduces the potential for a
nuisance alarm.
Leading authorities recommend that both ionization and photoelectric
smoke alarms be installed to help insure maximum detection of the vari-
ous types of fires that an occur within the home. Ionization sensing
alarms may detect invisible fire particles (associated with fast flaming fires)
sooner than photoelectric alarms. Photoelectric sensing alarms may detect
visible fire particles (associated with slow smoldering Hires) sooner than
ionization alarms.
Alarm Warnings
Fire: The red LED will flash and be accompanied by three long alarm
beeps followed by a verbal warning message "FIRE 1". The alarm pattern
will repeat until smoke is eliminated.
Carbon Monoxide: Four short alarm beeps followed by a verbal warning
"WARNINGI CARBON MONOXIDE!" This continues until the unit is reset
or the CO is eliminated.
Low Battery: One chirp followed by warning "LOW BATTERY." The red
LED light will flash. This pattern will continue every minute for at least
seven days. Under battery power, the "LOW BATTERY" voice only occurs
once every 15 minutes.
Voice Hush Indication: "HUSH MODE ACTIVATED" and "HUSH MODE
CANCELLED" voice announcement.
Peak Level Memory: If the alarm had detected a CO level of 100ppm
or higher when the Test/Reset button is pressed, the unit will announce
"CARBON MONOXIDE PREVIOUSLY DETECTED" to warn of the CO incident.

Specifications
The combination smoke and carbon monoxide alarm shall be Kidde model
KN-COSM4BA or approved equal. It shall be powered by 120VAC, 60Hz source
with two AA battery backup. The temperature operating range shall be between
40T and 100T (4'C and 3WC) and the humidity operating range shall be 10% -
95% relative humidity, non -condensing.
The unit shall incorporate an ionization smoke sensor with nominal sensitivity of
0.89%/ft. The CO sensor shall be of a fuel cell design and shall meet the sensitiv-
ity requirements of Underwriters Laboratories UL2034 Single and Multiple Station
Carbon Monoxide Detectors.
The combination alarm can be installed on the surface of any wall or ceiling following
the UUNFPA/Manufacturer's recommended placement guidelines. The alarm can be
installed on any standard single gang electrical box, up to a 4" octagon junction box.
The electrical connection (to the alarm) shall be made with a plug-in connector. The
unit shall provide optional tamper resistance that deters removal of the unit from the
wall or ceiling. No additional pieces shall be required to activate this feature.
A maximum of.24 Kidde devices can be interconnected in a multiple station
arrangement. The interconnect system must not exceed the NFPA (National Fire
Protection Association) limit of 18 initiating devices, of which 12 can be smoke
alarms. With 18 initiating devices (smoke, heat, CO, etc), interconnected, it is still
possible to interconnect 6 strobe lights and or relay modules.
The alarm shall include a test button that will electronically simulate the presence of
smoke and'CO and cause the unit to go into both modes of alarm. This sequence
tests the unit's electronics to ensure proper operation.
The CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the
following time range when exposed to the corresponding levels of CO.
70 ppm CO Concentration 60-240 minutes
150 ppm CO Concentration 10 - 50 minutes
400 ppm CO Concentration 4 -15 minutes
The combination alarm shall have two methods of warning for danger: a piezoelec-
tric horn that is rated at 85 decibels at 10 feet and a voice warning that identifies
the danger. For a CO incident, the hom will sound in the repetitive manner -four
(4) fast beeps, a short pause, four (4) fast beeps, a short pause. In between, the
unit will announce "Warning Carbon Monoxidel" In a Smoke incident, the horn
will sound in the repetitive manner - three (3) beeps, a pause, three (3) beeps, a
pause. In between, the unit will announce "FIREI"
The unit shall incorporate a 2 LED display. A green LED will be steady on when AC
power is present, flash every 60 seconds when in battery only mode, every second
to indicate alarm memory, and every 2 seconds to indicate the Hush" mode is
active. A red LED will flash in unison with the alarm sounder pattern.
The unit shall include the Hush- feature that silences the unit for approximately 9
minutes if a nuisance alarm condition occurs. The Green LED on the alarm will flash
every 2 seconds while in Hush- and will automatically reset itself. lf also provides
voice annunciation of 'HUSH MODE ACTIVATED" when Hush'" is activated and
"HUSH MODE CANCELLED" when the Hush cycle ends.
The unit shall also indicate a low battery warning utilizing each of the following
methods: a brief alarm chirp, the voice announcement of "Low Batteryl-
The unit shall at a minimum meet the requirements of UL 2034, UL217, NFPA72,
(chapter 112002 edition) The State of California Fire Marshall, NFPA101 (One
and two family dwellings) Federal Housing Authority (FHA), Housing and Urban
Development (HUD). It shall also include a 10-year manufacturers limited warranty.

The combination alarm should be installed to comply with all local codes
having jurisdiction in your area, Article 760 of the National Electric Code,
and NFPA 72. Make certain all alarms are wired to a single, continuous
(non -switched) power line, which is not protected by a ground fault
interrupter. A maximum of 1000 ft. of wire can be used in the intercon-
nect system. Use standard UL listed household wire 08 gauge or larger
as required by local codes).

Notes:
1. Table includes losses for four 90-degm bends and two end fittings. Tubing runs with larger numbers of bends or fittings shall be increased by an equivalent
length of tubing to the following equation: L = 1.3n where L is additional length (feet) of tubing and n is the number of additional fillings or bends.
2. EHD-Equivalent Hydraulic Diameter, which is a measure of the relative hydraulic efficiency between different tubing sizes. The greater the value of EHD,
the greater the gas capacity of the tubing.
