1) These instructions must be retained by the owner / user for future reference. For installation only in noncombustible locations. Gas units

are only to be installed in areas that have provisions for adequate air supply.

2) Position: For proper operation and drainage, steam generator must be level. It must be set near a floor drain. Attach 1 1/2" piping to all drain connections to carry exhaust steam away from the cabinet Ends of drain lines must vent to atmosphere to avoid back pressure. Allow a MINIMUM of 6" clearance to the rear and sides of the equipment. The surrounding area must be free and clear of combustibles.

3) Install in accordance with local codes and/or the National Electric Code ANSI/NFPA No. 70-1984. installation in Canada shall be in accordance with the Canadian Electric Code CSA Standard C22-1 A unit that is connected 10 electricity must be grounded. A wiring diagram is provided inside the relay box.

4) Connect supply lines for 140° — 160° hot water, and cold water, to the unit. Water pressure must be maintained between 35 and 60 psi. Locations and pressure data are shown on the connection drawing. Long hot water lines should be at least 1/2" IPS. Rush water supply lines thoroughly before connecting. Use water which is low in total solids content and low in gas content to prevent internal scaling, pitting and corrosion of the steam generator and carry-over of minerals into the steam. Water which is fit to drink can still contain highly detrimental impurities. Refer to Water Quality Requirements page.

5) Turn on water supply to steam generator. Water valve is inside of base.

6) Connect fuel supply

FOR YOUR SAFETY

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

For Steam Coil Steam Generators —

— Connect steam supply: Location is shown on the connection drawing. Incoming steam pressur e must be regulated between 35 and

45psi (30 — 45 psi for pressure steamers). Install a strainer ahead of the regulating valve. Rush line thoroughly before connecting.

— Connect the outlet end of the steam coil to an inverted bucket trap. Pill trap with water before installing. — Connect electricity if unit is equipped with electrical controls. Permanent 115V connection is required. Junction box location is

shown on the connection drawing. Unit must be electrically grounded by the installer.

For Gas Fired Generators—

— Post, in a prominent location, instructions to be followed in the event the user smells gas. This information shall be

obtained by consulting the local gas supplier.

7) Turn on electricity at control circuit switch on steamer console. A red light glows when electricity is on. If water level is correct, steam generator will operate by pressing the "reset" button. Heaters will not work without water in the steam generator. This manual reset button must be pressed to start up the generator initially, and to restart the steam generator after every shut oft. or power interruption. No attempt should be made to operate the equipment during a power failure.

8) Check to make sure that the water in the sight gauge glass automatically stays at about 2/3 full when the unit is started up.

9) When installation is complete and free of leaks, refer to Operating Procedures sheet

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 on an adhesive label attached to the unit To obtain an additional data sheet or label carrying servicing instructions, write to the Cleveland Range Company.

WARNING

No work should be done on the steam generator while it is pressurized or hot. Service of the steam generator should only be performed by a trained and experienced service technician, thoroughly familiar with servicing steam generators. 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.

Rigid regulations govern the design and construction of a boiler- However, the responsibility for the safe and efficient operation of a

Steam Generator (Boiler) Safety

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 iniury to personnel. M ost states, provinces and some cities have 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 manufacturer, The Cleveland Range Company delivers steam generators built to the 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 to which it is sent.

Safe and Efficient Boiler Operation Depends on Proper Installation

Install (the boiler in compliance with following regulations, where they apply:

— The National Fuel Gas Code. ANSI 2223-1-1984 — The local and municipal building code (plumbing and — Installation Codes for Gas Burning Appliances and electrical)

Equipment B149.1 and B149.2 — The state and city boiler laws

---The Cleveland Range Company Installation instructions. — The recommendations of the owner/user's under writers

— The National Electrical Code ANSI/NPPA 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 ease. A boiler will not operate property for very long if the water causes boiler corrosion or

scale. Even water which is 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 hole plate must be quickly stopped. Small leaks, if 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 by a length of pipe, or by other means, is dangerous because it may result in the breakage of pans, or injury. No attempts should be made to 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 for 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 is better to schedule a convenient replacement time than to wart for the boiler to fail. When a boiler older than 10 years is replaced the entire steam generator base assembly should be replaced for a number of reasons:

— Replacement pans 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.

CLEVELAND CONVECTION STEAMER OPERATING INSTRUCTIONS

NOTE: These instructions pertain to steamers equipped with self-contained steam generators (boilers). For 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. 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. Make sure that the steam tubes in the cooking compartments are in place and not loose.

2. Flip the toggle 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 10-12 pounds. You can now preheat the cooking compartments. Preheating need only be done once before the day's cooking.

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 returns to 10 pounds, cooking may begin in the steamer.

6. To preheat, close the compartment door with the palm of your hand on the latch. Turn the outer dial of the timer to 5 minutes and press its inner button. It will be several minutes before the arrow on the inner dial starts to move clockwise, toward the arrow on the outer dial. When the preheating is completed, the steam will automatically shut off and a buzzer will sound.

7. To cook, place the pan of food into the cooking compartment and repeat the operating procedure previously described (step #6) but set the timer for the length of time required, up to 30 minutes. The door may be opened for food inspection anytime during the cooking cycle, BUT KEEP HANDS OUT OF THE COOKING COMPARTMENT TO PREVENT BURNS.

8. If a cooking cycle longer than 30 minutes is desired, do not use the timer. Just depress the red "Manual" operation button to start the flow of steam. Remember, you must press the manual button again to shut the steam off. In either mode of operation, the red indicating light will glow when the compartment is in operation. In the manual mode, the timer can be used, but steam will continue to flow after the buzzer sounds.

9. At the end of each day's operation, flip the console toggle switch to the "Blowdown" position, open the door in the cabinet base and open the boiler drain valve, (red handle). This "Blowdown" drains the boiler and helps to keep it clean. When the boiler is empty, flip the console toggle switch to the "OFF" position, and close the boiler drain valve.

10. 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.

TO PROLONG LIFE AND MINIMIZE SERVICE REQUIREMENTS

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 steam tubes, 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. Once a week, remove and clean the compartment steam tubes. Lubricate the steam tubes' rubber "0" rings with cooking oil prior

to reinserting them into the compartments' back wall openings.

7. Steam tubes, drain screens, and pan slides are stainless steel, and can be washed safely in a mechanical dishwasher.

8. Always leave compartment doors ajar when not in use.

parts per million

(EXCEPT THOSE EQUIPPED WITH TWO PROBES)

WARNING: Steam under pressure may cause serious injury and bodily harm when it is accidentaily 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 or the steam generator when it is hot or pressurized.

Every steam generator shipped is 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) Reinstall 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-pound torque. Overtightening may cause uneven stress which may result in the weakening and possible breakage of the plate.

is shown on map, right. Areas shown in black have hardest water, while relatively soft water is found in white areas. Shaded area require supplemental feed water treatment to remove or to reduce the hardness.

This map is a general representation and exceptions do exist Consult a local water treatment specialist for a

water sample test.

60-120 parts per million 120-180 parts per million

above 180 parts per million

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 a 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 property. 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. Pitting indicates an excess acid condition. In either case, more protectors or more frequent replacement of them is 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 in 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 teed 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) M oderately hard water. Lass than 85 ppm.

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

Data Sheet—: 260-LC(R1)

START-UP MAINTENANCE PROCEDURES — STEAM GENERATOR

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

START-UP:

1) Open the cabinet base door and close the 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 water will automatically begin filling the generator.

3) When the water level in the sight gauge glass (on the generator) reaches— approximately 2/3 full (after approx- imately five minutes). 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 shows no stabilized water level, i.e., the gauge glass is completely empty or completely fitted, have the generator serviced.

4) In approximately 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 "Operating 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 of the generator and helps to prevent lime scale formation. When the generator is empty, flip the console toggle switch to the "OFF" position and dose 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 to pressurized or hot. Be sure all energy source are shut off before the tart of any work.

2) Even though the "Blowdown" re 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 and the inside can be inspected. The hand hole plate should be cleaned and examined each time 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(s) if necessary, and chemically descale the generator if it is coated with lime scale. A new hand hole gasket should always be installed.

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

4) Every steam generator is equipped with at least one corrosion resistor to reduce generator shell 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 a very hard, the feedwater must also be treated to remove the harmful mineral content.

Refer to separate 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 generator 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 more, 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 separate 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

27 parts per million

13 parts per million

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 compartment(s), leaving minerals behind that can become harmful to the steam generator. If minerals are allowed to accumulate inside the steam generator, they win 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 a the presence of dissolved salts of magnesium and calcium. Water softening will not affect the multitude of other minerals found in most water supplies. Because generator scale is the result or the precipitation of many 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 pre-treated, based upon 10 hours of use per day, and a Daily Blowdown, are as follows:

Total Dissolved Solids Less than 60 parts per million Total Alkalinity Less than Silica Less than

PH Factor

Consult a local water treatment specialist for an on-thepremises water analysis and for recommendations concerning steam generator teed 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 it treatment is applied, resulting in feed water quality meeting the prescribed standard, 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 sac months. Replace the corrosion resistors) 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 should be blown down after each 6 hours of use. Have the steam generator inspected, inside and outside, by a qualified technician every 3 months. If the corrosion resistor(s) is totally or nearly consumed, replace it. If the inside of the 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 and base, which can be identified by it’s powdered form, are safe and compatible 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 for a specific brand should be followed carefully. If 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, depressurized, and is cool. Open the hand hole access on the front of the generator and place approximately 8-10 pounds of sulfamic acid inside the generator. Put a new hand hole gasket on the 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 of 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, than 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 soda of soda 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.

INSTRUCTIONS

ELECTRIC LOW WATER FUEL CUT OFF FOR STEAM GENERATOR — 3 PROBE TYPE

WARNING: Service of the steam generator must be performed only

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 intermediate extension.

by trained and experienced service technicians.

The long probe, called "Low Water," is a safety sensor which shuts off 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 long life. If they do malfunction, it is generally because untreated hard feed water 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 property.

To eliminate the cause of scaling, refer to separate data sheets for feed water 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 piece 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 hot use an abrasive on the teflon insulator. If the old probe needs replacement, install a new one.

6) Assemble probe extensions to probes on inside of steam a generator so they hang an vertically, parallel to each other. Malfunctioning will occur if an extension touches any part of the steam generator or another probe extension.

7 ) If insulation on electrical wires to the probe shows signs of being broken, cut, or deteriorated, the wires should be

replaced.

8) Connect wire terminals on outside of steam generator to probe terminals as follows:

Red wire to the shortest probe. Turns water off. Black wire to the intermediate probe. Turns water on. White wire to the longest probe. Shuts off fuel (low water safety fuel shut -off).

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. It 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.

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 control's 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. turn control knob to "pilot". For main and pilot burner off, slightly depress and turn control knob to "off". 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

½”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.

1) Remove the pilot adjustment cover screw.

to prevent possible gas leakage.

Electrical connections in the pilot generator circuit must se clean 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)

GAS BOILER CONTROL CIRCUIT

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 off 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 for 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 SV2 is energized allowing the boiler to fill with water at the same time the primary circuit of Transformer T1 is

also energized.

2) The boiler will continue to fill until the water level reaches the Water Off probe extension completing the T1 secondary circuit, and energizing Relay Coil RC1

3) When Relay Coil RC1 is energized the normally closed contact opens, de-energizing Solenoid SV2 stopping the water

fill. The normally open contact is closed, completing 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 T1 is broken and the Relay Coil RC1 is de-energized.

2) When Relay Coil RC1 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 T1 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 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:

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 boilers 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 i 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 of 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 (eve! in the sight gauge is about 2/3 full.

12. Start up and observe steam generator long enough to see that it is operating property.

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 datasheets for maintenance instructions pertaining to scale problems.
