The burner and controls are listed by Underwriters' Laboratories, Inc.

Accordingly, the burner bears one of the UL labels indicating periodic

inspection of the production of this equipment.

All ASME tanks are built to the standards of Section IV of the American

Society of Mechanical Engineers code and are stamped with their symbol.

The National Board of Boiler and Pressure Vessel Inspectors papers are

furnished upon request. The NB number and HLW symbol (to the right)

are on the plate located just below cleanout on tank. (May be viewed by

removing cleanout cover on jacket).

IDENTIFICATION

The heater and burner rating plates or labels provide valuable information

to the installer and servicer. When ordering parts or inquiring about a

unit, be sure to include all information from the plates. See the picture on

page 2 for approximate location of the heater rating plate.

stage pump respectively, should match letter "O" or "T" of the heater

model.

If these codes do not match, the oil burner may not be the correct model

for the heater model purchased, Contact your State dealer for further

information and replacement , if required.

The heater model number is structured as follows:

OIL BURNER NAMEPLATE DECAL

The oil burner's nameplate decal (see page 2 for the approximate location

To provide the proper firing rate for each model heater, see SPECIFICATIONS:

there are burner models for each heater model in table 2.

When other than a State burner is used, this instruction manual can be

used as a general guide. The burner manufacturer's instructions will have

to be consulted on specific questions of wiring, air adjustment, etc.

All oil burners are UL defined as having "interrupted ignition" . . . meaning the

ignition is on during the flame establishing period only. Ignition is off when the

burner is off. Standard safety timing is 15 seconds.

Do not test the burner or control system before the heater is filled with

water. Follow the START-UP procedure in this manual.

For installations where gravity feed of fuel oil from the storage tank to the

heater is practical, an oil burner with a single-stage oil pump can be used.

The 940 series of burners have single-stage pumps which are shipped

for installation of a supply line to the tank only. A return line back to the

storage tank can be installed, if required, by making a small modification

to the pump, see the oil burner installation manual.

UNCRATING

Uncrate the heater by removing the outside mat and top locator. The

shipping pallet must be removed from the unit. It may be possible to

simply unbolt the base from the pallet and, with the help of two or more

persons, work the unit off the pallet. Some units will be too heavy and will

require the use of jacks or lifting equipment. Safely remove the pallet

and move the unit into position. Be Careful When Moving This Heater. It

will tip over easily.

For installations where gravity feed cannot be employed, (the storage

tank is located significantly below, or remote from, the heater) an oil burner

with a two-stage oil pump should be used. The 941 series of burners

have two-stage pumps which are shipped for installation of a supply and

return line to the tank. However, in situations where the return line is not

required (low lift installations), the pump may be modified to operate without

the line, see the oil burner installation manual.

LEVELLING

IMPORTANT

Install the heater plumb to the ground. If it is necessary to adjust the

heater, use metal shims under the channel type skid base.

The oil-fired water heater shipment consists of two packages, heater and

oil burner. Check to be certain the model number on the heater and oil

burner packages match. To assure matching equipment, see preceding

information.

LOCATION

The water heater should not be installed where the combustion air is

contaminated, see COMBUSTION AND VENTILATING AIR. Temperature

in the location must be above 32°F (0°C) and free of combustible dusts

and flammable gases or vapors.

SAFETY

•

The heater should be located in an area where leakage of the tank

or connections will not result in damage to the area adjacent to the

heater or to lower floors of the structure.

DANGER

BE SURE TO TURN OFF POWER WHEN WORKING ON OR NEAR

THE ELECTRICAL SYSTEM OF THE HEATER. NEVER TOUCH

ELECTRICAL COMPONENTS WITH WET HANDS OR WHEN

STANDING IN WATER. WHEN REPLACING FUSES ALWAYS USE THE

CORRECT SIZE FUSE FOR CIRCUIT.

•

When such locations cannot be avoided, a suitable drain pan should

be installed under the heater.

The pan should be at least two inches deep, have a minimum length

and width of at least two inches greater than the diameter of the

heater and should be piped to an adequate drain. The pan must

not restrict combustion air flow.

If it is necessary to reset the safety primary control, depress red button

one time only. If burner does not operate after depressing red button

one time, call serviceman.

•

The discharge opening of the relief valve should always be piped

to an open drain.

COMBUSTION AND VENTILATION AIR

GENERAL

•

Choose the point of major hot water usage, fuel supply and chimney.

Try to make hot water and oil piping as short as possible.

The water heater area should have sufficient air for satisfactory combustion

of oil, and proper venting and of safe ambient temperature.

When a heater is installed in an area where exhaust or ventilating fans

may create unsatisfactory combustion or venting, approved provisions

must be made to overcome the problem, see NFPA Standard No. 31,

Chapter 1.

Insulate hot and cold water piping where heat loss and condensation

may be a problem.

CLEARANCES

CHEMICAL VAPOR CORROSION

The heater has minimum clearances to combustible material, on a non-

combustible floor of: 6 inches (152 mm) from the sides and rear, 24 inches

(610 mm) from the front, and 18 inches (457 mm) from the vent connector.

These clearances are, as shown in fig. 3A to prevent possible fire hazard

conditions.

Water heater corrosion and component failure can be caused by the

heating and breakdown of airborne chemical vapors. Spray can

propellants, cleaning solvents, refrigerator and air conditioning refrigerants,

swimming pool chemicals, calcium and sodium chlorides, waxes, and

process chemicals are typical compounds which are potentially corrosive.

These materials are corrosive at very low concentration levels with little

or no odor to reveal their presence.

At least 24" (610 mm) of top clearances are recommended for vertical

vent installation.

Allow sufficient room at rear of heater for servicing of T&P relief valve.

Products of this sort should not be stored near the heater. Also, air which

is brought in contact with the water heater should not contain any of

these chemicals. If necessary, uncontaminated air should be obtained

from remote or outside sources.

At least 24" (610 mm) should be provided at the front of the unit for

proper servicing.

Units which are to be installed on combustible flooring must be supported

by a full layer of hollow concrete blocks, fig. 3, from 8" (203 mm) to 12"

(305 mm) thick and extending 12" (305 mm) minimum beyond the heater

in all directions. The concrete blocks must provide an unbroken concrete

surface under the heater, with the hollows running continuous and

horizontally. A 3/16" (4.8 mm) steel plate must cover the concrete blocks,

see fig. 3.

UNCONFINED SPACES (Building Construction)

NOTE: An unconfined space is defined as a space whose volume is not

less than 50 ft³per 1000 BTUH (4.83m³per kW) of total input of

allfuel burningappliances installed in that space. The unconfined

space may be thought of as extending to all areas which cannot

be separated by a door or door(s). All other spaces not fitting this

description, should be thought of as confined space.

1. In unconfined spaces in buildings of conventional frame, brick or stone

construction, infiltration will normally supply an adequate amount of

air for combustion and ventilation.

2. If the unconfined space is within a building of tight construction, eg.

weather stripping, heavy insulation, caulking, vapor barrier, ect., air

infiltration may be insufficient to support proper combustion and

ventilation, air shall be obtained from outdoors or from spaces freely

communicating with the outdoors.

PROPER INSTALLATION ON COMBUSTIBLE FLOORING

FIGURE 3

•

Follow the instructions under Part 2 of Confined Spaces (Room

Construction)

NOTE: If electrical conduits run under the floor of the proposed heater

location, insulate the floor as recommended above.

CONFINED SPACES (Room Construction)

1. All air from inside building (conventionally constructed buildings only):

The confined space shall be provided with the two permanent openings,

one within 12" (305 mm) of the ceiling and one within 12" (305 mm) of

the floor, fig. 4.

These models are factory supplied with a flue reducer which should

be installed on the top cover.

In venting systems where a continuous or intermittent back (positive)

draft is found to exist, the cause must be determined and corrected. In

some cases, a special vent cap may be required.

If the back draft cannot be corrected by normal methods or if a suitable

draft cannot be obtained, a blower type flue gas exhauster must be

employed to assure venting and correct combustion.

Note: A negative draft must be maintained in the vent piping.

Connections shall not be to a chimney, vent or venting system served by

a power exhauster unless the connection is made on the negative pressure

side of the exhauster.

The barometric draft regulator must be installed in the same room as the

heater, fig. 6. Locate the regulator as close as possible to the heater and

at least 18" (457.2 mm) from a combustible ceiling or wall. A manually

operated damper should not be placed in the chimney connector.

APPLIANCE AERATION FROM OUTDOORS (OPTIONAL

FOR CONVENTIONAL BUILDINGS, MANDATORY

FOR TIGHT BUILDINGS)

FIGURE 5

FLUE GAS VENTING

In the absence of any local codes, regulations, or vent pipe or chimney

manufacturer's recommendations, for oil fired equipment, follow the

suggestions below for designing and installing a venting system.

For these water heaters, it is recommended that an adequate chimney

be used for venting the flue gases. Type B, double wall, vent pipe should

be used as the vent connector pipe. However, where no chimney is

available, vent pipe may be used to construct a vent.

Where an existing chimney or vent is to be used, be sure that the chimney

or vent has adequate capacity for the number and sizes of appliances

being vented through it. Inspect the chimney or vent and remove all soot

or other obstructions which will retard free draft.

PROPER VENT CONNECTOR INSTALLATION

FIGURE 6

CHIMNEY

VENT CONNECTOR AND DRAFT REGULATOR

The oil-fired water heater must be connected to a chimney built in

accordance with accepted building code practice or listed factory built

type, Table 5. The exit point of the chimney flue gas must be at least 3'

(0.91 M) above the highest point where it passes through the roof of a

building. Also, it must be at least 2' (0.61 M) higher than any portion of a

building within 10' (3.05 M) of the chimney.

The chimney or vent connector diameter should be the same size as the

heater flue outlet, see Table 4. A minimum rise of 1/4" per foot (21mm/M)

of horizontal connector length must be maintained between the heater

and chimney opening, fig. 6. The connector length should be kept as

short as possible.

MULTIPLE HEATER FLUES

DRAIN VALVE AND ACCESS PANELS

The heaters are equipped with a 3/4" NPT drain valve mounted above

and to the left of the oil burner, see FEATURES, page 2.

When two or more oil-fired water heaters are connected to a single chimney

or vent there shall be sufficient draft available for safe combustion and

removal of combustion products to the outdoors from each heater. Refer

to local codes for connection details.

An access panel is located above and to the left of the oil burner and

covers the flame observation port, fig. 7. A plug is inserted into the flame

observation port and must be removed in order to look into the combustion

chamber. Always reinstall plug before replacing access panel.

Only one oil-fired water heater should be connected to any one type L

venting system.

A draft regulator shall be provided for each oil-fired water heater in a

multiple heater system.

DANGER

INCORRECT INSTALLATION CAN CAUSE IMPROPER OPERATION,

FIRE, ASPHYXIATION, SERIOUS PERSONAL INJURY OR DEATH.

NEVER OPERATE THIS WATER HEATER UNLESS IT IS PROPERLY

VENTED TO THE OUTDOORS AND HAS ADEQUATE COMBUSTION

AIR SUPPLY.

WATER PIPING

COMBUSTION CHAMBER ACCESS PORT - FIGURE 7

GENERAL

Another access panel is located above and to the right of the oil burner,

fig. 8. This panel covers the cleanout opening in the tank which is sealed

by a gasket and cover.

Select the piping diagram for the type of system to be installed from

pages 14 through 18. When a circulation pump is used in the system a

plug cock should be installed where indicated to regulate water flow through

the heater.

RELIEF VALVE

An A.G.A. design-certified and A.S.M.E.-rated temperature and pressure

relief valve is installed in the water heater . The relief valve has a discharge

capacity exceeding the maximum heater input rating and a pressure rating

not exceeding the working pressure shown on the rating plate of the heater.

A temperature and pressure relief valve must also be installed on any

potable water storage tank. This relief valve should have a temperature

rating of 210° F (98.9°C), a pressure rating not exceeding the lowest

rated working pressure of any system component, and a discharge

capacity exceeding the total input of the water heaters supplying water to

the storage tank.

TANK CLEANOUT PORT - FIGURE 8

THE PURPOSE OF A RELIEF VALVE IS TO AVOID EXCESSIVE

PRESSURE OR TEMPERATURE INTO THE STEAM RANGE, WHICH

MAY CAUSE SCALDING AT FIXTURES, TANK EXPLOSION, SYSTEM

OR HEATER DAMAGE.

Models having ASME tank construction will have two cleanout ports. One

port will be located as indicated above and the other will be located directly

opposite.

To avoid scalding or water damage, a drain line must be connected to a

relief valve to direct discharge to a safe location, A DRAIN LINE MUST

NOT BE REDUCED FROM THE SIZE OF THE VALVE OUTLET AND IT

MUST NOT CONTAIN ANY VALVES BETWEEN THE HEATER AND THE

RELIEF VALVE OR THE RELIEF VALVE AND THE DRAIN LINE EXIT.

IN ADDITION, THERE SHOULD NOT BE ANY RESTRICTIONS IN A

DRAIN LINE NOR SHOULD IT BE ROUTED THROUGH AREAS WHERE

FREEZING CONDITIONS MIGHT OCCUR. DO NOT THREAD OR CAP

THE DRAIN LINE EXIT. RESTRICTING OR BLOCKING A DRAIN LINE

WILL DEFEAT THE PURPOSE OF THE RELIEF VALVE AND MAY

CREATE AN UNSAFE CONDITION. Install a drain line with a downward

slope such that it naturally drains itself.

Occasionally, some water seepage will occur at a cleanout port. To correct

this situation, slightly tighten the cleanout cover bolts until the seepage is

eliminated. Do not over tighten the bolts or the cleanout gasket will be

damaged. Tighten each bolt gradually and alternate between opposed

bolts on the cleanout cover.

FUEL SYSTEMS

GENERAL

The Standard for the Installation of Oil Burning Equipment-NFPA No. 31,

local codes, and these instructions must be followed when installing the

tank, piping and burner. In addition, an oil pump installation sheet and oil

burner certificate are packed with the burner for use and completion by

the installer.

Your local code authority may have other specific relief valve requirements.

NOTE: These heaters are equipped with an automatic burner shutoff

system actuated by high water temperature.

On fuel systems with high pressures, a Webster "OSV" oil safety valve

(Webster Electric CO., Racine, Wisc.) will be required to reduce the oil

pressure at the burner pump. See FUEL PUMP, page 9, for pressure

ratings of the burner's pump.

CLOSED WATER SYSTEM

A closed system will exist if a back-flow preventer (check valve), pressure

reducing valve, or other similar device is installed in the cold water line

between the water heater and the street main (or well). Excessive pressure

may develope due to the thermal expansion of heated water causing

premature tank failure or intermittent relief valve operation. This type of

failure is not covered by the limited warranty. An expansion tank may be

necessary in the cold water supply to alleviate this situation, see installation

diagrams on pages 14-18. Contact the local plumbing authority.

This manual and the completed oil burner certificate (CS75) are to be left

with the user for future reference.

Figure 9 shows a typical single stage one or two line fuel system. When

two or more tanks are connected to one burner, the supply line from each

tank should run to a header fitted with an approved three-way valve.

Normally only one tank may be drawn at a time unless local codes permit

simultaneous feeding of two tanks on gravity type installations.

the GPO 86-199 which is set at 110 psig.

3. Place the flat washers and lock washers over the studs and fasten the

burner in place with the 3/8" - 16 nuts as shown.

All oil pumps are fitted for installation on single fuel line systems. The

pump may be adapted for two line service by using the by-pass Plug and

pump manufacturer's instructions packed with the burner.

Connect the oil line(s) and electrical wires to the burner as follows:

1. The oil pump manufacturer's instructions should be checked for

connection and bleeding information.

The single-stage pumps are for single-pipe or two-pipe installations, either

lift or gravity feed. On gravity feed installations the inlet pressure is not to

exceed 3 psig. On one pipe lift installations the lift is not to exceed 8 ft.

•

The burner is approved for use with fuel oil not heavier than No. 2.

2. An approved, separately fused circuit with disconnect switch should

be available for the oil burner. Using Figure 14, the wiring diagram

below as a guide:

The two-stage pumps are for two-pipe lift installations where the inlet

vacuum does not exceed 20" hg. vacuum.

OPERATION

DANGER

THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE

THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT WATER

TEMPERATURES REQUIRED FOR AUTOMATIC DISHWASHER AND

LAUNDRY USE CAN CAUSE SCALD BURNS RESULTING IN SERIOUS

PERSONAL INJURY AND OR DEATH. THE TEMPERATURE AT WHICH

INJURY OCCURS VARIES WITH THE PERSONS AGE AND TIME OF

EXPOSURE. THE SLOWER RESPONSE TIME OF CHILDREN, AGED

OR DISABLED PERSONS INCREASES THE HAZARDS TO THEM.

NEVER ALLOW SMALL CHILDREN TO USE A HOT WATER TAP, OR

TO DRAW THEIR OWN BATH WATER. NEVER LEAVE A CHILD OR

DISABLED PERSON UNATTENDED IN A BATHTUB OR SHOWER.

GENERAL

Never operate the heater unless the tank is filled with water and a

temperature and pressure relief valve is installed.

FILLING

1. Oil burner electrical disconnect switch should be in the "OFF position

2. Close the heater drain valve.

3. Open a nearby hot water faucet to allow the air in the system to escape.

4. Fully open the cold water inlet valve, filling the heater and piping.

THE WATER HEATER SHOULD BE LOCATED IN AN AREA WHERE

THE GENERAL PUBLIC DOES NOT HAVE ACCESS TO SET

TEMPERATURES.

5. Close the hot water faucet as water starts to flow from the opening,

Leave the cold water inlet valve fully open. The heater is now ready to

start-up if being placed in operation for the first time.

SETTING THE WATER HEATER TEMPERATURE AT 120°F (48.9°C)

WILL REDUCE THE RISK OF SCALDS. Some states require settings at

specific lower temperatures.

START-UP

Figure 16 shows the approximate time-to-burn relationship for normal

adult skin. Short repeated heating cycles caused by small hot water

uses can cause temperatures at the point of use to exceed the thermostat

setting by up to 20°F. If you experience this type of use, you should

consider using lower temperature settings to reduce scald hazards.

The following checks should be made by the installer when the heater is

placed into operation for the first time:

1. Check all factory and field made water, oil and electrical connections

for tightness. Also check flue gas disposal provisions on top the heater.

•

Field installed circulating pumps should be all bronze construction.

Be sure the oil burner, related piping, valves and controls are in place,

adjusted and ready for operation before turning on the electricity.

More than 5 minutes

3. Adjust the heater mounted control as follows:

FIGURE 16

•

THERMOSTAT (adjustable) set for desired water temperature.

It is suggested the thermostat be turned to the lowest setting which

satisfies the hot water requirements of the system. This helps

minimize scale formation in the heater.

Values for reducing point-of-use temperature by mixing cold and hot water

are available. Also available are inexpensive devices that attach to faucets

to limit hot water temperatures. Contact a licensed plumber or the local

plumbing authority.

•

HIGH LIMIT (not adjustable, manual reset) factory set to cutout at

195° F (90.5°C).

If the high limit is actuated, the safety primary control will cause

the oil burner to shut down. See SAFETY PRIMARY CONTROL,

page 21.

The water temperature is controlled by a thermostat, fig. 17, which has

two sensing elements. One sensor is located near the top of the tank and

the other is near the center. The thermostat is set in the lowest position

before the heater leaves the factory.

•

To reset the safety primary control, depress the red button on the

control.

Depress red button one time only. If burner does not operate after

depressing red button one time, call service man.

The thermostat temperature dial, fig. 17, is accessible by taking off the

access cover and removing the control cover. The dial is adjustable and

may be set for 120°F (48.9°C) to 170°F (76.6°C) water temperature, but

120°F is the recommended starting point. It is suggested the dial be

placed in the lowest setting which produces an acceptable hot water supply.

This will always give the most energy efficient operation. The temperature

control has a 4F° (2.2C°)fixed differential.

4. Turn on the oil burner electrical disconnect switch.

5. The heater will begin normal operation on the thermostat's "call for

heat".

6. To turn the heater off, open the electrical disconnect switch. If the

heater is to remain inoperative for a long period of time, close the

shutoff valve on the oil supply line.

HIGH LIMIT SWITCH (E.C.O)

WATER TEMPERATURE CONTROL

The dual bulb controller (fig.17) contains the high limit (energy cutoff)

sensor. The high limit switch interrupts main burner gas flow should the

water temperature reach 195°F (90.5°C).

In the event of high limit switch operation, the appliance cannot be restarted

unless the water temperature is reduced by 20F° (11.1C°) (approx.) and

the high limit reset button on front of limit control (fig.17) is depressed.

Continued manual resetting of high limit control, preceded by higher than

usual water temperature is evidence of high limit switch operation. Contact

your dealer or servicer if continued high limit switch operation occurs.

RELIEF VALVES

DRAINING

At least twice a year, the system relief valves should be checked to ensure

that they are in operating condition. To check a relief valve, lift the lever at

the end of the valve several times. The valve should seat properly and

operate freely. Water should flow while the lever is lifted.

The water heater must be drained if it is to be shut down and exposed to

freezing temperatures. Maintenance and service procedures may also

require draining the heater.

1. Turn off the oil burner electrical disconnect switch.

If water does not flow, remove the valve and inspect for obstructions or

corrosion. Replace with a new valve of the recommended size as

necessary. Inspection of the valve should be performed at least every

three years. Do not attempt to repair the valve, as this could result in

improper operating and a tank explosion. In areas with poor water

conditions, it may be necessary to inspect the T&P valve more often than

twice a year.

•

If required for draining the heater, turn off the oil line supply valve.

2. Close the cold water inlet valve to heater.

3. Open a nearby hot water faucet to vent the system.

4. Open the heater drain valve.

DANGER

5. If the heater is being drained for an extended shutdown, it is suggested

the drain valve be left open during this period.

BEFORE MANUALLY OPERATING A RELIEF VALVE, MAKE SURE

THAT DRAIN LINE HAS BEEN ATTACHED TO THE VALVE TO DIRECT

THE DISCHARGE TO AN OPEN DRAIN. FAILURE TO TAKE THIS

PRECAUTION COULD MEAN CONTACT WITH EXTREMELY HOT

WATER PASSING OUT OF THE VALVE DURING THIS CHECK

OPERATION.

•

Following FILLING instructions when restarting hot water service.

MAINTENANCE

If the temperature and pressure relief valve on the heater discharges

periodically or continuously, it may be due to thermal expansion of water

in a closed water supply system, or it may be due to a faulty relief valve.

GENERAL

Thermal expansion is the normal response of water when it is heated. In

a closed system, thermal expansion will cause the system pressure to

build until the relief valve actuation pressure is equaled. Then, the relief

valve will open, allowing water to escape, slightly lowering the pressure.

Water heater maintenance includes periodic tank flushing and cleaning,

and removal of lime scale. The oil burner should be inspected and adjusted

to maintain proper combustion. Where used, the water heating system

circulating pump should be oiled (See table 9).

The depth of lime buildup should be measured periodically. Heaters will

have about 2" (51 mm) of lime buildup when the level of lime has reached

the bottom of the cleanout opening or about 1" (25.4 mm) of lime buildup

if it has reached the drain valve opening. A schedule for deliming should

be setup, based on the amount of time it would take for a 1" (25.4 mm)

buildup of lime.

Your water supplier or local plumbing inspector will know how to best

correct this situation. Two common corrections are listed in the Checklist

and Service Information which appears later in this manual.

ABOVE ALL, DO NOT PLUG THE TEMPERATURE AND PRESSURE

RELIEF VALVE. THIS IS NOT A SOLUTION AND CAN CREATE A

HAZARDOUS SITUATION.

Example 1: Initial inspection shows 1/2" (12.7 mm) of lime accumulation

during the first 6 months of operation. Therefore, the heater

can be delimed once a year.

FLUSHING

Example 2: Initial inspection shows 2" (51mm) of lime

accumulationduring the first 6 months of operation.

Therefore, the heater should be delimed every 3 months.

1. Turn off the oil burner electrical disconnect switch.

2. Open the drain valve and allow water to flow until it runs clean.

3. Close the drain valve when finished flushing.

Following are the instructions for performing some of the recommended

maintenance. Oil burner inspection and adjustment should be performed

by a competent technician.

4. Turn on the oil burner electrical disconnect switch.

Download from Www.Somanuals.com. All Manuals Search And Download.

5. Inspect cleanout plate gasket. If new gasket is required, replace with

State Part no. 99038.

SEDIMENT REMOVAL

Water borne impurities consist of fine particles of soil and sand which

settle out and form a layer of sediment on the bottom of the tank.

6. Install cleanout plate. Be sure to draw plate up tight by tightening

screws securely.

For convenience, sediment removal and lime scale removal should be

performed at the same time.

7. Fill the water heater according to the FILLING section on Page 10..

8. Check for water leakage.

LIME SCALE REMOVAL

9. Replace outer jacket cover plate.

The amount of calcium carbonate (Lime) released from water is in direct

proportion to water temperature and usage, see chart. The higher the

water temperature or water usage , the more lime deposits are dropped

out of the water. This is the lime scale which forms in pipes, heaters and

on cooking utensils.

Flo-jug Method of Deliming

The Flo-Jug is the standard 5 gallon container for UN•LIME^®-or- it is

available as a deliming kit with UN•LIME^®, hose and fittings. Contact your

dealer, distributor or the State Water Heaters. Figure 18 illustrates most

of the following steps.

1. The heater should be prepared for deliming as described in the "Why?

When and How" booklet. The relief valve may also be delimed at this

time.

2. With the Flow-Jug upright:

•

Take off cap, remove cover under opening and install 3/4" x 4"

brass pipe nipple.

Drill or punch a 3/16" vent hole in handle. A stainless steel screw is

included with the Flo-Jug kit. This screw is to be installed in the

vent hole when Flo-Jug is not in use.

•

Remove drain valve from heater and insert a 3/4" x 4" drain nipple.

Connect the clamp 1" I. D. x 3" hole to Flo-Jug and drain nipple.

3. Lift the Flo-Jug to the POUR POSITION and permit the UN•LIME^®to

flow into the heater as rapidly as possible.

WATER USAGE IN GALLONS PER DAY POUNDS OF LIME

DEPOSITED VS. TEMPERATURE AND WATER USAGE

•

Be sure to keep the vent just above the liquid level.

Lime accumulation not only reduces the life of the equipment but also

reduces efficiency of the heater and increases fuel consumption.

4. Place the Flow-Jug in the DELIME POSITION.

The usage of water softening equipment greatly reduces the hardness of

the water. However, this equipment does not always remove all of the

hardness (lime). For this reason it is recommended that a regular schedule

for deliming be maintained.

•

It may be necessary to place the empty jug on its carton to trap the

solution in the heater.

Allow the UN•LIME^®to attack the water scale for 5 minutes.

Sediment and lime scale removal may be accomplished through the

cleanout opening furnished on the water heater, see FEATURES,

page 2. The heater must be drained, see DRAINING, page 11, before

removing cleanout cover on tank.

5. Lower the Flo-Jug to the DRAIN POSITION and allow the UN•LIME^®

to flow out of the heater as rapidly as possible.

•

Observe the vent hole and elevate the jug slightly if there is a

possibility of spillage.

To dissolve and remove the more stubborn mineral deposits, UN•LIME^®

Professional Delimer or equivalent should be used.

Deliming activity is indicated by foaming on the surface of the

solution.

UN•LIME^®Delimer is an easy-to-handle patented food grade acid

formulated specifically for lime scale removal from all types of water using

equipment and is available in 1 gallon (Part No. 4763) and 5 gallon (Part

No. 4813) sizes. Hydrochloric base acids are not recommended for use

on glass-lined tanks.

6. Continue the deliming process:

•

Raise jug to POUR POSITION. Allow solution to flood into heater.

Place jug to DELIME POSITION for 5 minutes. Solution is at work

in heater.

To clean heater through cleanout opening, proceed as follows:

1. Turn off water inlet valve. Turn off the oil burner electrical disconnect

switch. Open the nearest hot water faucet, then open the drain valve

and allow all water to drain from the heater..

•

Lower jug to DRAIN POSITION and allow solution to flow out.

Observe foaming.

7. After one hour, or earlier if the deliming activity (foaming) stops, inspect

the tank interior.

2. Remove outer cover plate from lower side of heater jacket.

3. Remove six(6) hex head screws securing tank cleanout plate and

remove plate.

•

Drain the UN•LIME® back into jug, DRAIN POSITION, and then

stand jug in DELIME POSITION.

4. Remove lime, scale. or sediment using care not to damage the glass

lining.

•

Remove clamp, hose and pipe nipple from heater drain opening.

Download from Www.Somanuals.com. All Manuals Search And Download.

•

Observe interior through opening - a small flashlight may be used

effectively.

SOOT REMOVAL

Soot must be removed semi-annually from the heater and flow passages

to insure efficient operation of the heater.

If the interior still shows water scale, the deliming process should

be continued.

To check UN•LIME® for continued use or reuse, place some lime

scale or white chalk into a glass with a small amount of the solution.

If the material is vigorously dissolved by the solution, the UN•LIME®

can be reused. If not, then UN•LIME® has been weakened and

should be replaced.

A TYPICAL HEATER FLUEWAY AND FLUE BAFFLE

FIGURE 19

1. Remove chimney connector and top cover of heater from heater. Clean

out all soot deposits from connector and chimney opening. A wire

brush is recommended for this operation.

2. Remove flue baffles by lifting from tank.

DELIMING THE GPO WATER HEATER

FIGURE 18

3. Using a wire brush, remove soot from flue passages in heater tank.

CAUTION: While cleaning tank flue passages, care must be taken that

brush does not come in contact with the top of the combustion

chamber as damage could occur to the combustion chamber

lining.

8. When deliming has been completed, the heater should be flushed for

3 to 5 minutes with fresh water.

•

Remove the deliming equipment, install the drain valve, open the

cold water inlet line and allow water to flow through heater and out

the drain valve. Don't forget to plug vent and cap opening in Flo-

Jug.

4. Remove oil burner assembly and using a vacuum cleaner, remove all

loose soot from combustion chamber area. Avoid contact with

combustion chamber as it can be damaged quite easily.

•

If flange gasket is damaged, replace with State Part No. 24165

9. When flushing is completed:

5. Upon completion of cleaning, reassemble the heater. (It may be

necessary to apply new sealer tape to the top cover to ensure proper

venting. New sealer tape can be ordered from State Water Heaters).

•

Fill heater being certain to expel air from tank through a nearby hot

water faucet.

•

Replace relief valve, removed for deliming.

Restore oil, water and electrical supply to heater.

Check for water leakage.

6. Return the heater to operation by following the start-up instructions

on page 10.

VENT SYSTEM

10.Flo-Jug Cleanup.

Examine the vent system every six months for obstructions and/or

deterioration of vent piping. Remove any soot or obstructions and replace

damaged vent piping.

•

Allow scale to separate from UN•LIME® and settle on bottom

of Flo-Jug.

ANODE ROD INSPECTION

•

Pour off UN•LIME® into plastic container and check for reuse.

Rinse sediment from Flo-Jug.

The anode rod is used to protect the tank from corrosion. Most hot water

tanks are equipped with an anode rod. The submerged rod sacrifices

itself to protect the tank. Instead of corroding the tank, water ions attack

and eat away the anode rod. This does not effect the water's taste or

color. The rod must be maintained to keep the tank in operating condition.

If UN•LIME® is reusable , pour back into Flo-Jug. Be sure to plug

vent and cap opening.

CIRCULATING PUMP

Anode rod deterioration depends on water conductivity, not necessarily

water condition. A corroded or pitted anode rod indicates high water

conductivity and should be checked and/or replaced more often than an

anode rod that appears to be intact. Replacement of a depleted anode

rod can extend the life of your water heater. Inspection should be conducted

by a qualified technician, and at a minimum should be checked annually

after the warranty period.

The water heater or water heating system may include a circulating pump.

Where used, it may need to be lubricated once every four months with

SAE No. 20 non-detergent motor oil or as directed by the manufacturer.

•

Place 2 or 3 teaspoons in the bearing oil cup and 10 to 12 drops in the

motor oil cups.

MANIFOLD KIT COMMERCIAL OIL FIRED WATER HEATERS

Precision cut type "L" all copper State manifold kits assure water flow

balance of all units. Without this balance, the full water heating and

storage potential of the system cannot be achieved. Plus, the units with

the higher water flow may have a shortened life. Unions and T & P

valves shown in piping diagrams are not included in the manifold kits.

Dimensions shown are for minimum space occupied by complete

assemblies. Service space in front of units must be added.

DANGER:

TEMPERATURE SETTING SHOULD NOT EXCEED SAFE TEMPERATURES AT

FIXTURES. SEE WATER TEMPERATURE CONTROL WARNING ON PAGE 10. IF

HIGHER PREHEAT TEMPERATURES ARE NECESSARY TO OBTAIN ADEQUATE

BOOSTER OUTPUT, ADD AN ANTI-SCALD VALVE FOR HOT WATER SUPPLIED

TO FIXTURES.

THREE UNIT MANIFOLD KIT (PART NO. 78693)

TWO UNIT MANIFOLD KIT (PART NO. 78692)

FOUR UNIT MANIFOLD KIT (PART NO. 78694)

2. Check the fuses.

The oil burner electrical disconnect switch usually contains fuses.

CHECK LIST AND SERVICE

INFORMATION

•

3. The capacity of the heater may have been exceeded by a large demand

for hot water.

IMPORTANT

The installer may be able to observe and correct certain problems which

might arise when the unit is put into operation or when it is refired after a

prolonged shut-down. HOWEVER, it is recommended that only qualified

servicemen, using appropriate test equipment, be allowed to service the

heater.

•

Large demands require a recovery period to restore water

temperature.

4. Colder incoming water temperature will lengthen the time required to

heat water to the desired temperature.

DANGER

•

If the heater was installed when incoming water temperature was

warm, colder water creates the effect of less hot water.

BE SURE TO TURN OFF THE ELECTRICITY WHENEVER POSSIBLE

OR APPROPRIATE WHEN CHECKING EQUIPMENT.

5. Look for hot water wastage and leaking or open hot water faucets.

ELECTRICAL WIRING REPLACEMENT

6. Sediment or lime scale may be affecting water heater operation. Refer

to MAINTENANCE for details.

If any of the original wiring, as supplied with the appliance, must be

replaced, it must be replaced with 16 AWG, or greater, copper conductor

with 600V, 105°C rated, thermoplastic insulation.

7. Heater or burner may be dirty.

NOT ENOUGH OR NO HOT WATER

•

Clean all heater flue pipes and flue connector.

Have burner properly cleaned and readjusted.

1. Be certain the oil burner electrical disconnect switch serving the water

heater is in the ON position.

Download from Www.Somanuals.com. All Manuals Search And Download.

8. Burner may not be firing at proper rate.

•

Excessive water pressure.

Excessive water temperature.

Faulty relief valve.

•

Check nozzle size.

Check fuel pump pressure setting.

GPO-199 . . . . . . . . . . . 110 psig (758 kPa)

Excessive water pressure is the most common cause of relief valve

leakage. It is often caused by a "closed system". If a check valve is in

the inlet system it will not permit the expanded hot water volume to equalize

pressure with the main. The relief valve must release this water or the

water heater or plumbing system will be damaged.

•

All others . . . . . . . . . . . 100 psig (689.5 lPa)

9. Burner may be short cycling. Short cycling (too frequent off and on)

of burner will cause sooting. If unit or burner become dirty at frequent

intervals, after correcting the dirt condition also correct the control

settings (or other cause of the short cycling).

When such a condition is encountered, local codes or inspection agency

should be consulted to determine which system is acceptable in your

area. These may consist of:

10.Oil burner fan wheel may be dirty.

•

Clean fan wheel with a stiff brush.

•

Installation of a second relief valve with lower settings than the

primary relief valve.

11. Draft regulator may be stuck.

Check to see if valve swings freely. Clean, if vane is stuck.

An expansion tank of suitable size and pressure rating and provision

to avoid water logging.

•

12.Priming control safety reset is open.

BURNER WON'T START

•

Reset safety switch on burner mounted primary control, see

SAFETY PRIMARY CONTROL, page 21.

When the thermostat calls for heat but the burner won't start, check to

make sure that you have proper voltage to the primary control.

13.Burner motor safety reset is open.

CAUTION

BURNER STARTS-WON'T OPERATE

When checking the low voltage circuit at the control, DO NOT TOUCH

THERMOSTAT WIRES TO FLAME DETECTOR TERMINALS AS THIS

WILL BURN OUT THE SENSOR IN THE SAFETY PRIMARY CONTROL.

If the voltage checks normal:

1. No oil in tank.

2. Oil line valve closed.

1. Flame detector may be sooted or seeing false light and will not let the

motor relay pull in.

3. Loose connection in primary control.

•

Check and tighten all wire connections, see SAFETY PRIMARY

CONTROL -page 21.

2. Loose wiring.

3. Bad flame detector (mounted inside housing beneath transformer).

4. Reset red safety button (primary control).

5. Defective primary control.

4. Electrode out of adjustment.

Clean firing head and readjust electrodes.

•

5. Clogged burner nozzle.

6. Reset motor protector.

•

Replace with new nozzle, see nozzle chart, page 9, table 8.

Nozzle should be replaced semiannually.

BURNER STARTS BUT FAILS TO RUN

6. Dirty filter.

Replace element in oil filter.

When the burner starts (motor running) but flame is not established, the

control will lock out on safety in about 15 seconds. If the control does not

lock out on safety, then the control is defective and should be replaced.

When the motor is running but flame is not established, then the problem

becomes:

•

WATER IS TOO HOT

1. Refer to WATER TEMPERATURE, page 10.

1. There is insufficient or no oil getting into the combustion chamber.

2. There is no spark to ignite the oil.

WATER HEATER MAKES SOUNDS

If the problem is insufficient or no oil getting into the combustion chamber,

check for the following:

1. Sediment or lime scale accumulations cause noises when the tank

bottom should be cleaned. Refer to MAINTENANCE, page 11-13 for

details.

1. Dirt or water in the supply line.

2. Slipping coupling between motor and pump.

3. Defective pump.

2. Some of the electrical components of the water heater makes sounds

which are normal.

•

Contacts click or snap as the heater starts and stops.

Transformers often hum.

4. Clogged, defective or too small a nozzle.

5. Oil tank empty.

WATER LEAKAGE IS SUSPECTED

6. Clogged filter in oil line.

1. Check to see if the water heater drain valve is tightly closed.

7. Restriction or kink in fuel line.

8. Ice in fuel line.

2. The apparent leakage may be condensation which forms on cool

surfaces of the heater and piping.

3. If the outlet of the relief valve is leaking it may represent:

9. Air leak in inlet connections.

Download from Www.Somanuals.com. All Manuals Search And Download.

1. Dirt or water in the supply line.

2. Pump loosing prime.

3. Bad motor.

If the problem is not getting a spark to ignite the oil, check for the following:

1. Loose wiring.

2. Red ignition transformer.

4. Erratic or low pressure at fuel pump.

5. Defective pump.

3. Low voltage.

6. Loose wiring or connections.

7. Clogged or damaged nozzle.

8. Oil tank empty.

4. Crack in electrode porcelain insulators.

5. Electrodes carboned or out of adjustment.

6. Weak or no contact between bus bars and terminals of transformer.

9. Oil tank not vented.

10.Clogged filter in oil line.

11. Ice in fuel line.

NORMAL START, BUT LOCKS OUT ON SAFETY

When the thermostat calls for heat and the burner starts normally but

then locks out on safety after about 15 seconds:

COMBUSTION TEST

SPECIFICATIONS

1. Improper setting of combustion air (too much air).

2. Weak or dirty flame detector.

GENERAL

3. Improper positioning of flame detector.

4. Bad flame detector.

A combustion test kit, capable of testing CO₂content, stack temperature,

draft and smoke must be available to aid in adjusting the unit and filling

out the Oil Burner Certificate. A pressure gauge is needed to measure

and adjust oil pump pressure.

5. Wiring from flame detector to primary not continuous or not making

good contact.

PROCEDURE

6. Bad safety primary control.

1. Check nozzle size, see Table 8 on Page 9.

2. Open air band about halfway and being certain heater is filled with

water, start burner.

7. Clogged, defective or undersized nozzle.

3. Check oil pump pressure. It should be 110 psig for the GPO-199 and

100 psig for all other models. Adjust setting as necessary.

SAFETY PRIMARY CONTROL

4. Allow burner to operate for 15 minutes before proceeding with test.

Normal Burner Cycle

5. After 15 minutes operation, check the draft in chimney connector,

about halfway between the heater and the draft regulator and adjust

the draft regulator until the correct reading is obtained.

Although a normal burner cycle does not create a service problem, it is

important to know what happens to better understand the problem when

the unit is not operating properly.

The instant the thermostat calls for heat, the flame detector sees darkness

and causes the sensor to conduct current. When the sensor conducts

current, the motor relay coil pulls in, starting the burner motor and

energizing the ignition transformer through the motor relay contacts. At

the same instant the motor relay coil pulls in, the safety heater is energized.

Draft in Chimney

Connector

.03 to .05

Inches of Water

6. Adjust air band until flame has smoky tips. Immediately increase air

supply until the smoky tips just disappear.

When flame is established, the resistance of the flame detector drops

(providing the flame detector can see the flame properly) which causes

the sensor to block the current. When the sensor blocks, the safety

heater drops out of the circuit and the motor relay coil continues to hold in

through a set of holding contacts on the motor relay until the thermostat

is satisfied and the burner shuts down.

7. Using combustion test kit, check smoke density and CO₂in the chimney

connector.

Preferably No. 1 Spot

Smoke Density

CO₂

(Not Over No. 2 Spot

9% to 12%

FLAME FAILURE AFTER NORMAL IGNITION

•

Adjust air supply with air band to achieve the highest CO₂readings

with an acceptable smoke density reading. Test and readjust as

necessary.

If, for some reason, there is a flame out, the flame detector sees darkness

which causes the sensor to conduct current and again energize the safety

heater. In approximately 15 seconds the safety contact will open and

shut down the burner. The safety contacts of the safety primary control

are the manual reset type, which means that the red safety button must

be reset before trying again for ignition. When this occurs, allow about 5

minutes for safety heater to cool before depressing the red safety button.

8. Check the stack temperature halfway between the heater and the

draft regulator.

Min.

400°F (204°C)

600°F (315°C)

Stack

Temperature

Max.

Depress red button one time only. If burner does not operate after

depressing red button one time, check combustion chamber. If

combustion chamber is soaked with oil the combustion chamber must be

replaced.

•

If stack temperature is too high, check for a soot accumulation in

heater or excessive oil pump pressure.

9. Recheck combustion efficiency against specifications when final

adjustments have been made.

Some of the possible reasons for flame failure after normal ignition has

occurred are:
