Instructions For Steam Generator Care

Protect your steam generator, prolong its life and preserve its performance by giving it the required daily attention, on a regular schedule. Follow servicing instructions for your steam generator which are printed on Data Sheet 260-LC in your Owner s Manual, and also or an adhesive label attached to the unit. To obtain an additional data sheet or label carrying servicing instructions, write to the Cleveland Range Company.

No work should be dorm on the steam generator while it pressurized or hot. Service of the steam generator should only be performed by a trained and experienced service technician, thoroughly My familiar with servicing steam generators. When maintenance or repairs are required, contact a located food service equipment service agency, or call the factory, or a factory representative for the name and address of one in your area.

WARNING

Steam Generator (Boiler) Safety

Rigid regulations govern the design and construction of a boiler. However, the responsibility for the safe and efficient operation of a boiler shifts to the owner/user after the boiler leaves the factory.

A sound boiler if improperly installed, or if improperly maintained, or if improperly repaired, will create a dangerous situation and may cause injury to personnel. Most sates, provinces and some cities nave a boiler safety law. Many underwriters require that their clients' boilers comply with these boiler safety laws. These safety laws call for action by the boiler manufacturer and action by the boiler owner/user. As a manufactur er. The Cleveland Range Company delivers steam generators built me ASME Boiler Code. Section IV. which have been inspected by a National Board Inspector. Also. each Cleveland Range Company boiler is built to comply with the boiler safety law of the state t o which it is sent

Safe and Effecient Boiler Operation Depends on Proper Installation Install the boiler in compliance with following regulations, where they apply:

— The National Fuel Gas Code. ANSI Z223.1-1984 —— installation Codes for Gas Burning Appliances and

Equipment B149.1 and B149.2

— The Cleveland Range Company Installation instruc-

tions

— The National Electrical Code ANSI/NFPA No.70-1984

The water for the boiler should be analyzed by a reputable boiler water specialist to see if the quality will permit safe and efficient boiler operation. Water treatment is becoming increasingly necessary because the quality of water sources is deteriorating. although treatment will not be required in every case. A boiler will not operate properly for very long if the water causes boiler corrosion or scale. Even water which 13 safe to drink may be detrimental to a boiler. Refer to Water quality Requirements page for details.

Safety Requires Periodic Inspection and Maintenance

Any leaks around the boiler's hand note plate must be Quickly stopped. Small leaks, it unchecked, cause corrosion and pitting on the boiler face around the hand hole gasket, making it unsealable.

Application of undue stress on the parts that are used to seal the boiler's hand hole opening, in an attempt to seal an unsealable opening, by sledging the handle of the wrench, by increasing the leverage of the wrench a length of pipe. or by other means, is dangerous because it may result the breakage of parts, or injury. No attempts should be made 10 tighten up the nut on the retaining stud beyond the recommended 15 foot pounds of torque.

When a repair affecting the safety of the boiler is necessary. call a National Board Inspector consultation and advice as to the best method of making the repair, so that the completed work will get his approval. Repairs to the boiler must conform to the applicable provisions in the ASME. Code or the National Board Rules for Repairs.

A boiler will last many years before it has to be retired from service. Periodic inspection will reveal the approaching

retirement time. It a better to schedule a convenient replacement time than to wait for the boiler to fail. When a boiler older man 10 years is replaced, the entire steam generator base assembly should be replaced for a number reasons:

— Replacement parts become increasingly difficult to obtain for older controls. — Dependable performance of the new controls can be assured for a longer time. — The new steam generator, including controls, will comply with the latest industry and safety standards.

PRESSURE STEAMER OPERATING INSTRUCTIONS

NOTE: These instructions pertain to steamers equipped with self-contained steam generators (boilers). Forr steamers direct-connected to a remote (in -house) steam source, disregard those instructions which are directly and solely related to the self-contained steam generator. These instructions are to be retained by the owner/user for future reference.

1A Open the cabinet base door and close the drain valve if it is open.

B Make sure the hot and cold water supply valves are open

C For steamers equipped with a gas-fired steam generator (boiler) follow the lighting instructions noted on the instruction label displayed on

the unit before continuing to instruction in item 2.

2 Flip the t oggle switch on front of the cabinet console to "ON" The red console light should then glow and the boiler will automatically

begin filling with water (if it is not already full).

3 After approximately five minutes (after water appears in the sight gauge), depress the ""START" reset button on the console. This will

energize the electric heater elements or ignite the gas burners. This cannot be accomplished until the boiler is full of water.

4 in approximately 15 minutes you will notice the console's steam pressure gauge register 5 pounds. (10 pounds if the boiler is also supplying

steam to a kettle- The upper pressure gauge will register 5 pounds.) You can now preheat the cooking compartments.

5 Compartments should be preheated before use and should be kept hot between loads. If a Kettle and steamer are to be used at the same

time, always heat the kettle unit first. When kettle contents begin to simmer, preheat the steamer compartments- When pressure on the boiler gauge returns to 10 pounds, cooking may begin in the steamer

6 Close and latch door securely. Turn bar handle clockwise until the door gasket just touches the compartment face 7 Start steam supply by pulling steam valve handle out. If fined with automatic timer, set timer for 5 minutes. At the start, compartment

thermostatic traps should release air and wet steam tor about two minutes, then shut off.

8 Seal compartment door by turning bar handle clockwise just until steam leakage stops. DO NOT OVERTIGHTEN. 9 At the completion of the 5 minute preheatin g cycle, push steam valve slowly in, to avoid boilovers. This shuts off the steam supply and also

depressurizes and drains the compartment. If fitted with an automatic timer, the steam shuts off automatically and a bell rings when the timer reaches zero. Setting the timer to "Off" stops the bell.

10 To open compartment door, turn bar handle counter-clockwise and delatch. 11 Cooking can now begin by following the above operating steps #6 through #10, but setting the timer for the required cooking time- At the

end of a cooking cycle 40 minutes long or longer, or when defrosting frozen foods, wait at least two minutes for the compartments) to depressurize and drain before opening the compartment door.

CAUTION: After each cooking cycle, ensure that all water is draining, and not accumulating in the compartment. Should a drain become obstructed, it must be cleared before attempting to cook in that compartment.

12. At the end of each day's operation, flip the console toggle switch to the "Blowdown" position, open t he door in the cabinet base and open the boiler drain valve, (red handle). This "Blowdown" drains the boiler and helps to keep it dean. When the boiler is empty, flip the console toggle switch to the "OFF" position and dose the boiler drain valve

13. It is recommended that the boiler be refilled with water after the "Blowdown" is performed. This can be accomplished by flipping the toggle switch to the "ON" position for a period of five minutes and then returning the switch to the "OFF" position.

1. Blow down the steam generator daily.

2. A periodic boiler inspection must be performed by a qualified serviceman to prolong its life and to minimize service calls

3. At the end of each day's operation, wash the pan slides, drain screen covers, door gaskets, and compartment interiors with mild detergent and warm water- Thoroughly rinse with clean water. Rinse water should drain freely through the compartment drain openings. If it does not, the drain must be cleaned before using the steamer.

4. Once a week. flush each compartment drain with a food service equipment drain cleaner and a deliming solution 5 Once every three months, shut off the water supply (hot and cold), and clean the water line strainers.

6. Compartment thermostatic traps can be disassembled and cleaned, by hand or in a mechanical dishwasher. This procedure is recommended if the traps act sluggishly, as they may if contaminated by grease or other film. If cleaning fails to restore the trap's proper functioning, replace the trap. For more detailed thermostatic trap servicing instruc tions., refer to Data Sheet 260-LH.

7. Shelves, drain screens, and pan slides arc stainless steel, and can be washed safely in a mechanical dishwasher.

8. Exterior Care: Allow steamer 10 cool before washing. Use the same cleaners and cleaning procedures as for other kitchen surfaces of stainless steel and aluminum. Mild soapy water, with a clear water rinse, ;s recommended. DC no: allow water to run into electncal controls- Always turn off equipment power before using water to wash equipment.

9. Compartment Door Care: a. When doors are closed tor preheating or cooking, turn bar handle just enough to stop steam leakage. Overtightening shortens gasket life. b. When doors are open or unlatched. Do not turn bar handle. c Always leave compartment doors ajar when not in use, to extend gasket life and to prevent gaskets from adhering to the steamer.

Unnecessary compression of a gasket shorten it s life.

d Keep bar handle screws clean. Lubricate frequently but not excessively. e. Door gaskets provide many months of service when care is taken to operate doors properly. When a gasket finally wears and does not

maintain an effective seal, it must be replaced. Door gaskets can be replaced easily without special tools or cement, and the steamer may be used immediately afterwards- Remove the old gasket and dean the channel. being careful not to damage the channel. The new gasket can then be pressed into place. Insert the gasket in the corners of the channel first, adjusting the slack evenly between the comers - Then work from the comers to the center. Ridges hold the gasket firmly. The gasket is designed to be oversize, so once it is compressed into the door's channel, it remains firmly in place.

PRESSURE STEAMER SAFETY

FOR YOUR SAFETY

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

Being the owner of a steamer carries with it the responsibility for Keeping it in as safe a condition as when it was shipped from the factory. Safe steamer operation dictates that every pressure steamer must have the following safety inspection at least every 12 months.

1. Steam Valve Linkages

Have a qualified serviceman examine the steam valve linkages which are attached to the inlet and exhaust valves' operating handles on the left side of the steamer. This pivoted linkage, which is attached to both the steam inlet valve and the steam exhaust valve, must prevent the door's latch from disengaging from its catch when the steamer compartment is pressurized. It is important that the linkage operates as described so that the steamer door cannot be opened when the compartment is pressurized.

It is also important that when the steam valve is closed, the exhaust valve should open. The proper operation of the steam inlet valve and the steam exhaust valve should be confirmed and observed while the steam is on.

2. Pressure Gauge Check each pressure gauge. Gauge pointer must return to zero when the steam generator is shut down. Look

for signs of water, rust, corrosion, or scale, inside the pressure gauge. A faulty pressure gauge should be replaced immediately.

a Door Gaskets

Inspect and replace compartment door gaskets once a year, or sooner if they are torn or hardened. The use of a hardened gasket produces undue stress in the parts which comprise the door enclosure and may result in breakage and injury.

4. Compartment Thermostatic Trap

Observe compartment thermostatic traps for proper operation. A good compartment trap, at start-up of a cooking cycle, is normally open and releases air and wet steam briskly for a few minutes. then holds steam within compartment. If brisk venting doesn't begin immediately at start-up, or if brisk venting continues without stopping, and the compartment trap is over a year old, it should be cleaned, or a new one installed- Refer to data sheet 260-LH for details

5 Compartment Steam Exhaust Valves and Drain Valves

Make sure that the compartment steam exhaust valves, and the drain lines attached to them, are free of food buildup internally and are venting freely to the atmosphere. If drain lines from other steam-consuming equipment have been connected to the drain line from the steamer, the other drain lines should be disconnected. Never operate a compartment without the drain screen cover in place.

6. Refer to separate data sheets for steam generator operation, maintenance, and safety procedures.

WARNING

Service of steam cooking equipment should only be performed by a trained and experienced service technician, thoroughly familiar with servicing steam equipment. No work should be performed on the steamer while it is pressurized or hot. Be sure all energy sources are shut off before the start of any work. When maintenance or repairs are required, contact a local food service equipment service agency, or call the factory. or a factory representative, for the name and address of one in your area.

PRESSURE STEAMERS: THERMOSTATIC TRAP AND

COMPARTMENT DOOR GASKET REPLACEMENT

The thermostatic trap and door gasket on your steamer stop the escape of steam from the compartment during operation. Steam leakage from either source will cause loss of pressure. which will result in longer cooking time. wasted Steam and excessive condensation.

To keep your steamer operating at peak efficiency. thermostatic traps and compartment door gaskets require periodic replacement Frequency of replacement vanes from one piece of equipment to another depending on the amount of usage, and frequency and quality of maintenance.

A normal thermostatic trap at Startup releases air and wet steam briskly for the first few minutes, then holds steam within the compartment. During cooking, the trap will also release accumulated condensate ana a small amount of air

It brisk venting doesn't begin immediately at startup or if brisk venting continues for much longer than two minutes. and the compartment trap is over a year old, it should be cleaned, or removed and a new one installed.

A compartment trap less than a year old may act sluggishly only because it is contaminated by grease and other film. To remove a thermostatic trap. unscrew the union nut as shown on the sketch. To clean the trap. unscrew the threaded! diaphragm cover from the body and wash the entire assembly. A more thorough cleaning can be accomplished by removing and disassembling the trap. and washing the entire assembly in a mechanical dish washer. With proper tools, the threaded diaphragm cover can be unscrewed from the body. and the thermostatic diaphragm can be unscrewed from the diaphragm cover, if the trap does not work property after thorough cleaning. install a new one. If the steamer is used heavily for cooking foods contain ing large amounts of fat or starch. periodic cleaning is recommended as a routine procedure

Replace the gaskets on compartment doors once a year. or sooner if they are torn or hardened. Door gaskets can be replaced easily without special tools or cement, and the steamer may be used immediately afterwards.

Remove the old gasket and clean the channel, being careful not to damage the channel. The new gasket can then be pressed into place. insert the gasket in the corners of the channel first, adjusting the slack evenly between the comers. Then work from the comers to the center.

Ridges hold the gasket firmly. The gasket is designed to be oversize, so once it is compressed into the door's channel, it remains firmly in place.

START-UP MAINTENANCE PROCEDURES — STEAM GENERATOR

IMPORTANT: These instructions must be followed in order to prevent premature failure of the steam generator

START-UP:

1) Open the cabinet base door and close me drain valve if it is open (Red Handle lever marked "blowdown")

2) Flip the toggle switch on front of the cabinet console

to "ON" (up position). The red console light should then glow and wter will automatically begin filling the generator.

3) When the water level in the sight gauge galss (on the generator) reaches approximatley 2/3 full (afer approximately five minutes0. depress the "ON" reset button on the console. This will energize the electric heater elements or ignite the gas burner. If the sight gauge glass is completely filled, have the generator serviced.

4) In approximatley ten minutes you will notice the steam pressure gauge, on the console, register the steam pressure contained inside the generator.

5) Cooking may now begin. Refer to "Cooking" and "Opening Procedure" data sheets for specific instructions.

MAINTENANCE:

1) At the end of each day's operation, while the generator is pressurized, flip the console toggle switch to the "Blowdown" position, open the door in the cabinet base and open the generator's drain valve.(red handle). This "Blowdown" procedure drains the water out f the generator and helps to prevent lime scale formation. When the generator is empty, flip the console toggle seitch to the "OFF" position and close the generator's drain valve. It is recommended that the generator be refilled with water after the "Blowdown" is performed. This can be accomplished by flipping the toggle switch to the "ON" position for a period of five minutes and then returning the switch to the "OFF" position.

CAUTION:

Service on the generator should only be performed by a trained and experienced service technician, thoroughly familiar with servicing steam generators. No work should be done on the steam generator while it is pressurized or hot. Be sure all energy sources are shut off before the start of any work.

2) Even though the "Blowdown" is performed faithfully each day, it will still be necessary to periodically inspect the inside of the generator. The generator's hand hole plate should be removed at regular intervals so that it is removed. If the hand hole plate is chipped or cracked, or over three years old, install a new one. Replace the corrosion resistor if necessary, and chemically descale the the generator if it is coated with lime scale. A new hand hole gasket should always be installed.

3) It will be necessary to periodcally have scale accumulations removed from the inside of the steam generator by a qualified service tchnician. Generator descaling instructions are provided on a seperate data sheet. Failure to periodically remove scale from the inside of the generaotr will result in greatly reduced generator life.

4) Every steam generaotr is equipped with at least one corrosion and scaling. This corrosion resistor is sacrificial and must be replaced at regular intervals just before it is entirely consumed. In areas where the water is very hard, the feedwater must also be treated to remove the harmful mineral content.

Refer to seperate data sheets for corrosion resistor servicing instructions.,feedwater treatment information, and hand hole plate servicing instructions.

5) Check the safety valve once a week while steam generaotr is pressurized. Test by pulling safety valve extension wire. Valve must open freely and snap closed when released. If it does not or if it drips constantly, a new safety valve is needed.

6) If the steam generator is to be left idle for three months or mre, it should be drained and dried out and the hand hole plate left off.

7) Water level in the sight gauge normally should be about 2/3 full. This level is maintained automatically.

Refer to seperate data sheet for either mechanical or water fill servicing instructions.

8) If gas fired the lighting instructions are on the AGA rating plate. Pilot burner is lit through hole in panel at bottom of steam generator. This panel should never be left off as this will damage the controls. Burners will not light without water in the steam generator.

WATER QUALITY REQUIREMENTS — STEAM

GENERATOR PROTECTION AND MAINTENANCE A steam generator, or boiler unlike other types of water- using kitchen equipment, distills the water in order to make steam. Nearly all feed-water sources contain dissolved minerals in varying degrees of concentration. As this water is boiled, pure steam rises from it's surface, upward to the cooking compartments, leaving minerals behind, that can become harmful to the steam generator. If minerals are allowed to accumulate inside the steam generator, they will solidify as a scale. Then malfunctioning will occur, and serious equipment damage may result.

The use of good quality generator feed water is the responsibility of the owner/user. The use of poor quality feed water could void equipment warranties. The minimum treatment required in most areas is water softening, although local water conditions may require more intensive pretreatment than simply a water softener. Scale problems occur when feed water is high in hardness, total dissolved solids, silica, and alkalinity. Water softening will only reduce the water's hardness which is the presence of dissolved salts of magnesium and calcium. Water softening will not affect the multitude of other minerals, the best property to control, for generator feed water, is total dissolved solids, not just hardness. the recommended minimum water quality standards, whether untreated or pretreated, based upon 10hours of use per day, and a Daily Blowdown are as follows:

TOTAL DISSOLVED SOLIDS less than 60 parts per million TOTAL ALKALINITY less than 27 parts per million SILICA less than 13 parts per million pH FACTOR greater than 7.5

Consult a local water treatment specialist for an on the premises water analysis and for recommendations concerning steam generator and feed water treatment (if required) in order to remove or reduce harmful concentrations of minerals.

If the recommended water quality requirements are met without supplemental treatment or if treatment is applied resulting in feed water quality meeting the prescribed standards the steam generator will need to be blown down only once each day. In addition the inside of the generator requires an inspection (for excessive lime accumulation and consumed corrosion resistors) only once every six months. Replace the corrosion resistor and chemically descale the generator as required.

If a pre-treatment unit cannot be installed, and the recommended water quality requirements are not met, the following procedures should be followed in order to achieve maximum steam generator service life. The steam generator is heavily coated with scale, have it chemically descaled by a qualified service technician.

INSTRUCTIONS FOR CHEMICALLY DESCALING STEAM GENERATORS

Warning: Steam under pressure may cause serious injury and bodily harm when it is accidentally or carelessly released. Improper handling of acid could cause serious permanent injury. Therefore, service of the steam generator should only be performed by trained and experienced personnel, thoroughly familiar with servicing generators.

There are a number of commercial descaling chemicals available produced by various manufacturers. Those utilizing a sulfamic acid base, which can be identified by its powdered form are sage and compatable with our food preparation equipment. It is imperative that the acid used for descaling be FDA approved for use in food preparation equipment. Various manufacturers may include additional chemicals to increase potency and therefore, instructions are not provided with the deliming chemical you purchase the following general guidelines may be followed.

WARNING: Exercise care when handling acid. Avoid contact with skin, eyes, or clothing. Wear safety glasses or face shield along with rubber gloves and rubber apron. In case of exposure to clothing, remove clothing and flush with water. In case of exposure to skin or eyes, flush with water for 15 minutes and get immediate medical attention. Do not take internally. Keep out of the reach of children.

Be sure the generator has been drained, de-pressurized, and is cool. Open the hand hole access plate on the front of the generator and place approximately 8-10 pounds of sulfamic acid inside the generator. Put a new hand hole plate and replace the hand hole plate tightening the bar and nut assembly to a maximum of 15 foot pounds torque. The generator must be completely filled with hot water (fill the generator beyond its normal, automatic fill point to 2/3 up in the sight gauge.) On mechanical fill generators this can be accomplished by adding weight to the float or removing the float and regulating the fill level with a hand valve in the water supply plumbing. On electric fill generators (with probes) this can be accomplished by temporarily jumpering terminals #3 & #4 of the water control relay. Turn the main on-off toggle switch to the "ON" position then turn the switch to the "OFF" position when the generator is completely filled. Let the solution stand for several hours, then flush with water. Rinse with a solution of bicarbonate of sods to neutralize any acid residue and again flush with water.

CAUTION: Never tighten the hand hole plate nut when the steam generator is in use, hot, or otherwise pressurized. Never tighten nut over 15 foot pounds torque. Overtightening may cause uneven stress, which may result in the weakening and possible breakage of the plate.

MAINTENANCE INSTRUCTIONS FOR STEAM GENERATORS

(EXCEPT THOSE EQUIPPED WITH TWO PROBES)

WARNING: Steam under pressure may cause serious injury and bodily harm when it is accidentally or carelessly released. Therefore, service of the steam generator should only be performed by trained and experienced personnel, thoroughly familiar with servicing steam generators.

CAUTION: Never work on the steam generator when

it is hot or pressurized.

Every steam generator shipped in equipped with at least one corrosion resistor (cathodic). The larger capacity steam generators will have two corrosion resistors.

The hand hole plate and gasket on your steam generator stops the escape of steam through the hand hole opening during operation.

1) Turn off all energy sources to steam generator. Drain steam generator.

2) Remove hand hole cover plate from steam generator.

3) Hang corrosion resistor from the right side of the front stay rod, away from the probes. Clean scale and rust off a portion of the stay rod so the hanger will rest on the bright, bare metal.

4) Re-install the hand hole plate, along with a new gasket.

The hand hole plate should be cleaned and examined every time it is removed. If the hand hole plate is chipped or cracked or over three years old, install a new one. Because continuous use and possible abuse cause metal fatigue which weakens the hand hole plate. a new one should be installed at least every three years.

CAUTION: Never tighten the hand hole plate nut when steam generator is in use, hot, or otherwise pressurized. Never tighten nut over 15 foot pounds torque. Overtightening may cause uneven stress, which may result in the weakening and possible breakage of the plate.

CLEVELANO RANGE CO, 1333 EAST 179th ST., CLEVELAND. OHIO 44110

Replace the gasket whenever the hand hole plate is removed or replaced. Keep a spare gasket on hand at all times. Replace the gasket at least once a year, or sooner if it is cracked, torn, or hardened.

Leakage of water past the hand hole plate should not be allowed to continue as this will cause pitting of the metal in contact with the gasket.

5) After re-installing the hand hole plate, close the steam generator drain valve. Turn on energy sources.

6)Start up and operate steam generator long enough to observe that it is operating properly.

The corrosion resistor is sacrificial and must be replaced at regular intervals just before it is entirely consumed. Frequency of replacement can only be established by a regular inspection for how much of the protector remains and whether scaling or pitting has begun. Scaling indicates a very hard water condition. In either case, more protectors or more frequent replacement of them in necessary. The best way to reduce servicing time and to assure long generator life is to provide feed water that is low in solids content and low n gas content. Water that is fit to drink can still be high in impurities that are highly detrimental to a steam generator. Consult a water treatment specialist in your area for recommendations concerning steam generator feed water treatment.

Under average conditions, the corrosion resistor provides about six months of service. An average condition would meet each of the following tests:

1. Less than 8 hours of steam generation a day.

2. One generator blowdown every day

3. Moderatley hard water. Less than 85 ppm.

4. Water containing less than 60 ppm Total Dissolved Solids.

SERVICING INSTRUCTIONS STEAM PRESSURE ADJUSTMENTS

WARNING: Adjustments must be made only by trained and experienced service personnel.

Normally there is no need to make pressure adjustments on a new steamer, because the proper settings are made at the factory.

In some cases however, the factory setting may shift due to shaking in transit, and resetting will be required after installation. The factory pressure settings shown on the accompanying chart should never be exceeded.

For Gas and Electric Steam Generator

Steam pressure is controlled with two pressure switches located toward the upper-front of the cabinet either to the extreme right.

The left switch is the operating pressure switch. This switch controls the pressure in the steam generator, which is the pressure indicated on the steam generator pressure gauge. The right switch is a high limit, pressure safety control. It breaks an electric circuit to shut off the energy source if the steam pressure rises above a safe level. Each switch has a screw on top of the case to permit the pressure set point to be adjusted without removing the cover. The correct settings are shown in the accompanying chart. The pressure switch indicator scale is for reference only. Actual pressure should be read on the pressure gauge and the pressure switch adjusted to produce the proper pressure gauge reading. Some models may also have a pressure reducing valve to control the pressure in the steam line to the steamer The adjustment of this discussed further on.

For Steam Coil Steam Generator

The steam supply to steam coil generators is controlled by one of two methods.

Steam generator pressure may be controlled by a pilot operated pressure regulating valve. The steam generator pressure can be adjusted by turning the adjusting collar, identified on the sketch. A steel rod is provided to turn the collar. The correct settings are shown in the accompanying chart.

On steam coil generators equipped with an electric solenoid valve to control the steam supply to the steam generator, one or two pressure switches control the steam generator pressure. To adjust the switch(es), turn the screw on the top of the case to achieve the pressure reading shown in the accompanying chart.

Pressure Reducing Valve-Adjustment and Care A screw at the top of the valve body, as shown on the sketch, permits the pressure set point to be adjusted. The locknut must be loosened before adjustment is made, and tightened after. Turning adjustment screw into housing raises pressure. If excessively high or low pressure

cant be corrected by adjustment, install a new valve. To eliminate erratic performance, the internal steam strainer should be cleaned periodically. The strainer can be reached by unscrewing the large hex head plug at the bottom of the valve

body.

PROBE SYSTEM: ELECTRIC WATER FILL AND ELECTRIC LOW WATER FUEL CUT OFF FOR STEAM GENERATOR — 3 PROBE TYPE

WARNING: Service of the steam generator must be performed only by trained and

During operation of the steam generator. The water level is maintained automatically by unequal length probe extensions inside The probes and extensions must be kept clean and free of scale deposits in order to function properly

The probe extensions are sensors in a control system which monitors and maintains the water level between the end of the short probe extension

and the end of the intermediat e extension.

The long probe, called "Low Water." is a safety sensor which shuts off

experienced service technicians.

the fuel supply if there is insufficient water in the steam generator. Since the control system is all electric and these parts don't move or

wear, they can be expected to have a Ions life. If they do malfunction, it is generally because untreated hard feedwater is being used in the steam generator. This forms scale on the submerged ends of the probe extensions and on the top horizontal surfaces of the probes. After this scale is removed, the parts will function properly.

To eliminate the cause of scaling, refer to separate data sheets for feedwater treatment information and corrosion protector servicing instructions. Probes and probe extensions should be wiped clean each time the corrosion protector is replaced.

Erratic operation may result from loose connections on either end of the probe. The external end of the probe has a nut to hold the wiring terminal snugly to the probe. This nut, if loose, may be tightened, firmly but gently. Too much torque will turn the center peice of the probe and misalign the attached probe extension inside, causing the probe to become inoperative.

inside the steam generator, the screw which holds the probe extension to the probe may be loose, allowing the probe extension to swing or rest against some part of the steam generator. This can be corrected by removing the hand hole plate and reaching inside to align and hold the probe extensions vertically while tightening the screws.

To Service the Probes or the Probe Extensions

1) Turn off all utilities and fuel to steam generator. Drain Steam generator.

CAUTION: Never work on the steam generator when it is hot or pressurized.

2) Remove probe cover on outside of steam generator to expose probe terminals. Examine for loose wiring terminals.

3) Remove hand hole cover plate from steam generator. See separate data sheet for instructions.

4) Remove probe extensions from probes on inside of steam generator, clean off scale, and re-install Or. install new probe extensions if preferred.

5) Remove scale from the probe (see sketch above) Do not use an abrasive on the teflon insulator. If the old probe needs replacement, install a new one.

9) Re-install hand hole plate and install a new gasket. The hand hole plate should be cleaned and examined each time it is removed. If the plate is chipped or cracked it should be replaced

immediately. Because continuous use and possible abuse can cause metal fatigue which weakens the hand hole plate, a new one should be installed at least every three years. Replace the gasket at least once a year —or sooner if it is cracked or hardened.

10) Replace probe cover and check to make sure that the cover does not contact probes.

11) Close steam generator drain valve. Turn on utilities and fuel supply to steam generator.

12) Operate and observe steam generator long enough to insure that it is functioning properly. Low Water Fuel Cut Off Test

Proper operation of the "Low Water" probe extension should be checked periodically, by someone who is thoroughly familiar with the equipment.

To Test: Open the drain of the steam generator while fuel is on- When the water has drained below the "Low Water" probe, the fuel should shut off automatically- Indication of fuel shut off should occur just as the water level in the sight gauge drops from view. If it does. close the drain, allow the steam generator to refill, and resume normal operations. If the fuel does not shut off. immediately turn the on-off toggle switch to the "off position, and follow the steps outlined under "To Service the Probes or the Probe Extensions" as given on the reverse side of this sheet.

STANDING PILOT-IGNITION TYPE GAS CONTROLS FOR GAS- FIRED STEAM GENERATORS

CAUTION: The following procedures, as well as other work on the gas controls, should be performed only by a trained and experienced service technician, thoroughly familiar with gas controls.

Built in gas controls assure safe and automatic operation of the pilot and main burners of the steam generator The controls consist of a pilot generator (thermocouple and a unit called the combination gas control This latter unit consists of a gas valve operator

and servo gas pressure regulator Generally, there is no need to make an adjustment to any portion of the gas system. The main burner orifices and the pilot burner orifice installed at the factory are correct for the kind of gas specified on the purchase order Also. the primary air supply to the main burner is properly adjusted for complete combustion.

Lighting and Shutdown Instructions Flip electrical switch on. Open water valve Open gas valve Slightly depress and turn control knob to "off" for 5

minutes before lighting gas. Turn control knob to "pilot." depress it completely, and light pilot burner. Continue to hold Knob in for about 60 seconds, then release. Pilot burner is lighted through hole in panel at bottom of steam— generator Never leave panel off. as this will damage controls. Turn control knob to "on". Depress electrical switch. for main burner ignition Burners will not light without water in the steam generator. For main burner off. with pilot on control knob to pilot". For main and pilot burner off. slightly depress and turn control knob to "of" Flip electrical switch off

Occasionally due to regional differences in the gas supply the pilot burner flame may require adjustment.

A normal flame is mostly blue and steady, and envelops 3/8" to 1/2 of the tip of the pilot generator, as illustrated at right

The pilot gas adjusting screw can be found under a cover screw located near the gas control knob. illustrated below

To adjust the pilot flame:

1) Remove the pilot adjustment cover screw 2 Turn PILOT FLOW ADJUSTMENT SCREW clockwise-—to

decrease or counterclocKwise—to increase pilot flame.

3) WARNING: Be sure to replace cover screw after adjustment to prevent possible gas leakage

Electrical connections in the pilot generator circuit must be dean and secure. Because the pilot generator operates in a severe environment, it may eventually need a replacement. The time before replacement will vary from one piece of equipment to another, depending on the amount of usage. The pilot generator (thermocouple) should generate 450-750 MV in an open circuit condition. When a malfunction is traceable to the combination gas control unit. it is recommended that the entire unit be replaced with a new one. rather than attempting repairs to the old unit.

WARNING: To prevent the danger of possible gas leakage, the installer must be a trained and experienced service technician, thoroughly familiar with gas controls.

HOW THE ELECTRIC (WARRICK RELAY) WATER LEVEL CONTROLS OPERATE — ON GAS FIRED STEAM GENERATORS (WITH 3 PROBES)

Inside Cleveland Range Co- boilers which have electric water level controls, there are three probe extensions vertically oriented above the water with their lower ends positioned at various levels

Water is admitted to the boiler and is shut oft in response to the water level sensed by the tips of the short and the medium length probe extensions The electrical conductance of the water is used in this system tor controlling its level. The third probe extension is a low water safety cutout sensor and

operates on the same principle. Operation Sequence — Water Level Control

Assume an empty Boiler To fill. close Switch S for the following operations:

1) Solenoid SV, is energized allowing the boiler to fill with water at the same time the primary circuit of Transformer T, is also energized.

2; The boiler will continue to fill until the water level reaches the Water Off probe extension completing the T, secondary circuit, and energized Relay Coil RC.

3) When Relay Coil RC. is energized the normally closed contact opens, de -energizing Solenoid SV; stopping the water fill. The normally open contact is closed, complet ing the circuit to the Water On probe.

When the water boils away below the end of the Water On probe extension the following occurs:

1) The secondary circuit of Transformer T, is broken and the Relay Coil RC, is de-energized

2) When Relay Coil RC, is de-energized the normally open contact opens, breaking the circuit to the Water Off probe extension. And. the normally closed contact closes, energizing Solenoid SV; allowing the boiler to fill as in Step 2 above.

Operation — Low Water Safety Cutout

When Swit ch S is closed the following operations occur

1) The primary circuit of Transformer T2; is energized.

2) When the water level reaches the low water safety cutout probe extension and the momentary reset switch is manually closed. Relay Coil RC, is energized.

3) When Relay Coil RC; is energized the normally open contacts close, completing the low water safety circuit through Contacts 7 and 8 and completing the circuit through Contacts 3 and 4. completing the 750 millivolt pilot generator circuit and allowing the gas control package valve to operate.

If the water level drops below the Low Water Safety Cutout probe extension, the following occurs:

1) The secondary circuit of Transformer T2 is broken and the Relay Coil RC2 is de -energized- Contacts 7 and 8 and 3 and 4 open. breaking the 750 millivolt circuit

1)) The secondary Circuit of Transformer T, is broken and the Relay Coil RC, is de -energized.

2) When Relay Coil RC, is de -energized the normally open contact opens, breaking the circuit to the Water Off probe extension. And. the normally closed contact closes, energizing Solenoid SV2 allowing the boiler to fill as in Step 2 above.

Operation — Low Water Safety Cutout

When Switch S is closed the following operations occur

1) The primary circuit of Transformer T2 is energized.

2) When the water level reaches the low water safety cutout probe extension and the momentary reset switch is manually closed. Relay Coil RC2 is energized.

3) When Relay Coil RC2 is energized the normally open contacts dose, completing the low water safety circuit through Contacts 7 and 8, and completing the circuit through Contacts 3 and 4. energizing Contactor Coil C which closes the heater circuit

If the water level drops below the Low Water Safety Cutout probe extension, the following occurs:

1) The secondary circuit of Transformer T2, is broken and the Relay Coil RC2 is de -energized- Contacts 7 and 8 and 3 and 4 open. breaking the circuits to Contactor C., thereby turning off the heaters.

Manufacturer reserves right of design improvement or modification, as warranted.

The Contactor C, will not operate until water level in the boiler is normal and the reset switch is operated.

Operation-Boiler Drain Condenser To activate the Boiler Drain Condenser System .close switch S by placing toggle in the down position. To drain boiler, open boiler drain ball valve. The heat from the boiler drain water will dose the normally open thermal switch TS and energize the condenser solenoid valve SV3,. To de-activate the Boiler Drain Condenser System open switch S by moving toggle to center off position.

STEAM COIL WIRING DIAGRAM

HOW THE ELECTRIC LOW WATER SAFETY SHUT -OFF OPERATES ON

STEAM COIL (ELECTRIC OPERATED) STEAM GENERATORS

Operation — Low Water Safety Shut-Off When Switch S is closed the following operations occur

1. The primary circuit of Transformer T is energized.

2. When the water level reaches the low water safety cutout probe extension and the momentary reset switch is manually closed. Relay Coil RC is energized.

3. When Relay Coil RC is energized, the normally open contacts close, completing the low water safety circuit through Contacts 7 and 8, and completing the circuit through Contacts 3 and 4. energizing Solenoid SV2, allowing steam to flow into the boiler's steam coil.

If the water level drops below the Low Water Safety Cutout probe extension, the following occurs:

1. The secondary circuit of Transformer T is broken and the Relay Coil RC is de-energized. Contacts 7 and 8 and 3 and 4 open, breaking the circuits to Solenoid SV2. thereby shutting off the flow of steam to the boiler's steam coil.

The steam Solenoid SV2 will not operate until water level in the boiler is normal and the reset switch is operated.

Operation — Boiler Drain Condenser

To activate the Boiler Drain Condenser System close Switch S by placing toggle in the down position. To drain the boiler, open the boiler drain ball valve. The heat from the boiler drain water will close the normally open Thermal Switch TS and energize the condenser Solenoid Valve SV3. To deactivate the Boiler Drain Condenser System open Switch S by moving toggle to the center off position.

SERVICING INSTRUCTIONS — MECHANICAL WATER FILL FOR STEAM

GENERATOR

The water level in the sight gauge should normally be about 2/3 full. If it is not, then (1) the water valve may be scaled up or (2) the water valve plunger disc is in need of replacement or (3) the adjusting screw at the top of the valve plunger is set incorrectly or (4) the float needs to be replaced.

WARNING: Steam under pressure may cause serious injury and bodily harm when It is accidentally or carelessly released. Therefore, service of the steam generator should only be performed by trained and experienced personnel, thoroughly familiar with servicing steam generators.

To service the water valve:

1. Turn off all utilities and fuel to steam generator. Drain steam generator.

CAUTION: Never work on the steam generator while It is hot or pressurized.

2. Remove hand hole plate from steam generator. Refer to separate data sheet for proper procedures and cautions.

3. (Inside the steam generator as shown on the diagram). Remove the float arm pivot screw. Disengage float arm assembly.

4. Lift out valve plunger disc and install new plunger disc.

5. Remove scale from valve seat and other internal valve surfaces.

6. Re-insert plunger in valve.

7. Install float arm assembly and check the adjustment. Float travel should be approximately 6 inches.

8. To increase the travel, turn adjusting screw clockwise. To decrease, reverse.

9. Re-install hand hole plate, never applying more than 15 ft./lbs- torque to the nut. The hand hole plate should be cleaned and examined every time it is removed. If the hand hole plate is chipped or cracked, or over three years old, install a new one. Because continuous use and possible abuse cause metal fatigue which weakens the hand hole plate, a new one should be installed at least every three years- Replace the gasket at least once a year — or sooner if it is cracked or hardened. Replace the hand hole gasket when re-installing the hand hole plate.

10. Close steam generator drain valve. Turn on utilities and fuel.

11. Check the water level. Proper level in the sight gauge is

about 2/3 full.

12. Start up and observe steam generator long enough to see

that it is operating properly.

13. After the valve plunger disc is installed, order more to have spares on hand at all times.

If hard water scale created the problem, the use of more corrosion resistors or more frequent replacement of them is required. Refer to separate data sheets for maintenance instructions pertaining to scale problems.
