Installation

UNPACKING

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
Immediately after unpacking the steamer, check for possible shipping damage. If the steamer is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, verify that the type of gas supply (natural or propane) and electrical service agree with the specifications on the rating plate located on the left side panel as you face the front of the braising pan. If the supply and equipment requirements do not agree, contact your dealer immediately.

Installation Codes and Standards
Installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1, as applicable.

1. The appliance and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at pressures in excess of 1/2 psi (3.5 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

Electrical grounding must be provided in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.
The electrical diagram is located on the inside of side panel of left hand console.

EXHAUST FANS AND CANOPIES: Canopies are set over ranges, ovens and kettles for ventilation purposes. It is recommended that a canopy extend 6 inches past appliance and be located 7.5 feet from the floor. Filters should be installed at an angle of 45 degrees or more with the horizontal. This position prevents dripping of grease and facilitates collecting the run- off grease in a drip pan, usually installed with the filter. A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Makeup air openings approximately equal to the fan area will relieve such vacuum. In case of unsatisfactory performance on any appliance, check operation with exhaust fan in the “OFF” position.

WALL EXHAUST FAN: The exhaust fan should be installed at least two feet above the vent opening at the top of the unit.
CLEARANCES: Adequate clearance must be provided in aisle and at the side and back. Adequate clearances for air openings into the combustion chamber must be provided, as well as for serviceability.

All units must be installed in such a manner that the flow of combustion and ventilation air are not obstructed. Provisions for an adequate air supply must also be provided. Do not obstruct side of the unit, as combustion air enters through this area.
Information on the construction and installation of ventilating hoods may be obtained from the standard for “Vapor Removal from Cooking Equipment”, NFPA No. 96 (latest edition), available from the National Fire Protection Association, Batterymarch Park, Quincy, MA, USA, 02269.

To Install

1. Uncrate carefully. Report any hidden freight damage to the freight company immediately.
2. The pressure relief valve is located at the right rear of the unit. This area should be kept clear and should not be in an area where operators will normally stand. The elbow on the relief valve should be turned toward the floor. A maximum 3 foot, 3/4” diameter pipe may be used to extend to the floor, but must not be piped directly to a drain. It must vent to the atmosphere.
3. Set the unit in place. Be certain to maintain minimum clearances as stated above.
4. To level the unit use a spirit level in all directions on the top of the kettle (lid up). Adjust the bottom foot on each leg to overcome an uneven floor.
5. Mark hole locations on floor through anchoring holes provided in flanged adjustable feet.
6. Remove appliance and drill holes in locations marked on floor and insert proper anchoring devices.
7. Set unit back in position and re-level left to right and front to back.
8. Bolt and anchor appliances securely to the floor.
9. Seal bolts and flanged feet with silastic or equivalent compound.
10. Appliance location must allow air supply to unit and obstruction free clearance for air opening into the combustion chamber.
11. Make service connections as indicated.
12. Check the pressure gauge on the front panel before operating. If the pressure gauge does not indicate green vacuum zone (below 0 psi), see “Re-establishing Vacuum” section under SERVICE, after completing installation instructions.

GAS CONNECTION

The serial plate on the lower right side of the unit indicates the type of gas your unit is equipped to burn. DO NOT connect to any other gas type.
A 3/4” NPT line is provided at the rear for the connection. Each unit is equipped with an internal pressure regulator which is set for 3.5” W.C. manifold pressure for natural gas and 4.0” W.C. for propane gas. Use 1/8” pipe tap on the downstream side of the combination valve for checking pressure.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance. A steady pressure, minimum 6” W.C. for natural gas and minimum 11” W.C. for propane gas, is recommended. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable drop. Fluctuations of more than 25% on natural gas, and 10% on propane gas, will create pilot problems and affect burner operating characteristics. Contact your gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt, or other foreign matter before connecting the line to the unit. It is recommended that an individual manual shut off valve be installed in the gas supply line to the unit. Use pipe joint compound which is suitable for use with LP gas on all threaded connections. Test pipe connections thoroughly for gas leaks.

WARNING
All connections must be checked for leaks, after the unit has been put in operation. Use soapy water only for testing on all gases. Never use an open flame to check for gas leaks.

NOTICE

• If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code CSA B149.1, as applicable.
• If this equipment is being installed at over 2,000 feet altitude and was not so specified on order, contact service department. Failure to install with proper orifice sizing may void the warranty.

Water Connection

On units equipped with an optional water fill valve connect a water line (minimum 1/4”) to the valve with a 1/4” NPT female fitting. Units with dual (hot and cold) valves must have the hot water line connected to side with the hot water valve (red) and cold water line to the cold water valve (blue). Plastic or rubber hose is not recommended, as it may melt against the hot kettle side.

Electrical Connection

WARNING
Do not connect the kettle to the electrical supply until after the gas connection has been made.

Daily Operation

Daily operation should consist of turning on the power switch and setting thermostat for the desired temperature.
It is recommended the kettle be preheated prior to use. Milk or egg based products should be placed in the kettle before heating however, to prevent sticking. The kettle is preheated when the cooking light goes off the first time.
At the end of the day, or if the kettle will not be used for some time, shut the unit down by turning the power switch to “OFF”.
Clean as required or on a daily basis. See “CLEANING INSTRUCTIONS” section.

End Use Tips
For easier cleaning add cold water to the kettle immediately after removing contents.
When preparing foods containing vinegar or tomatoes, or those which have a high salt content, clean the kettle immediately after using to prevent pitting.
Do not use salt to clean the kettle. This will scratch the surface.
If using salt water to cook shellfish, be sure to rinse and wash the kettle thoroughly after use.
Bring milk and egg products slowly up to temperature in a cold kettle to prevent product from adhering to the sides. When preparing milk-based products do not preheat the kettle.
When planning actual cooking capacity, allow room at top for stirring without spilling.
When preparing puddings from a mix, place the powder in a cold kettle, add a small amount of liquid, and stir to form a thin paste. Turn on the kettle and add the remainder of the liquid. Continue as per recipe instructions.
When browning meat, bring the kettle up to temperature before adding. This will seal the juices in the meat.

Gas Saving Tips
Use these reminders to help develop energy-saving procedures and habits. Using less natural or propane gas saves energy as well as money.

1. Turn off when not in use.
2. Limit preheat times.
3. Use lid when possible.
4. Maintain equipment.

Cleaning

WARNING

• Disconnect the power supply to the appliance before cleaning or servicing.
• Never spray water into electric controls or components!
• The equipment and its parts are hot. Use care when operating, cleaning and servicing.

CAUTION
Do not use cleaning agents that are corrosive.

Your kettle should be cleaned immediately after each use or when cooking a different product. Before cleaning, check that the kettle has cooled enough to touch it.

1. Rinse the inside of the kettle thoroughly and drain to remove any food particles.
2. Using a nylon brush, clean the kettle with a mild detergent and water. Never use steel wool or scouring powder as it will scratch stainless steel. Plain steel wool can leave small pieces of steel which can rust.
3. Rinse the inside of the kettle thoroughly with clean water. Drain the kettle by tilting or the tangent draw-off valve, depending on model, to allow the detergent and water solution to drain.
4. Wipe the exterior of the kettle with a clean, damp cloth.

WARNING
If you are cleaning a valve that is assembled to a kettle, be sure the kettle is completely empty of any product.

Draw-Off Valve Cleaning

1. If equipped with a tangent draw-off valve, turn the large hex nut on the draw-off valve counterclockwise until it is completely disengaged from the threads. Grasp the valve knob and slowly pull out the valve stem and disk. Do not allow the disk to come in contact with hard surfaces as it can be damaged and cause valve leakage. Wash the valve stem, disk and handle. Insert a nylon brush, wet with detergent and water, into the valve body and tangent draw-off tube. Brush vigorously.
2. Replace the valve stem assembly and turn the hex nut until snug. Rinse the kettle with clean warm water.
3. Leave the draw-off valve open when the kettle is not in use.

Dairy Draw-Off Valve Cleaning

1. Remove the plug by first removing the handle, then turn the plug to line up with the pin and pull with both hands. It is important to use both hands because the plug is heavy.
2. Put the plug in a plastic pail that contains a mild soap solution. A plastic pail works best, as it reduces the possibility of nicking or scratching the plug. If the plug gets scratched it may not seal correctly and could leak.
3. Use a soft cloth or soft brush and clean all surfaces.
4. Using both hands remove the valve from the soap and rinse well in another plastic pail that contains fresh water.
5. Wash out the kettle as normal.
6. Once the kettle is washed out, return the plug into the body. Be sure the plug is inserted into the notch and turned. Ensure the plug is tight and secure before letting go of it.

If you are cleaning a body and plug assembly, remove the plug and follow the above procedures. When finished with the plug, follow the same instructions for washing the body. Always use both hands when handling the plugs. Reassemble the plug into the body and use as normal.

NOTICE
Draw-off valve has a vulcanized rubber coated stem for better sealing. Do not over tighten. This may cause the rubber to pull away from stem and permanently damage it. This is not covered under warranty.

What to Do if Surface Rust Appears
Metal utensils should never be used as they will scratch the surface of the equipment and rust may begin to form. To remove surface accumulation of rust from the inadvertent use of such utensils, the following procedure may be used.

CAUTION
Improper use of this procedure may damage your appliance!

1. Use undiluted white vinegar with a non-abrasive scouring pad (plastic) or cloth on the affected area to remove the rust stain. The appliance should not be heated and remain at room temperature during the entire cleaning process.
2. If the stain resists removal, additional exposure time with vinegar may be required, to a maximum of one hour.
3. Thoroughly wash all of the vinegar away with fresh clear water. Dry the surface completely and allow one hour before using the appliance to cook.

Following daily and period maintenance procedures will prolong the life for your equipment. Climatic conditions – salt air – may require more thorough and frequent cleaning or the life of the equipment could be adversely affected.

Stainless Steel

To remove normal dirt, grease or product residue from stainless steel, use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth. Never use vinegar or any other corrosive cleaner.
To remove grease and food splatters or condensed vapors that have baked on the equipment, apply cleanser to a damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines. Rubbing cleanser as gently as possible in the direction of the polished lines will not mar the finish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION.

Soil and burn deposits which do not respond to the above procedure can usually be removed by rubbing the surface with SCOTCH-BRITE™ scouring pads or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL WOOL as any particles left on the surface will rust and further spoil the appearance of the finish. NEVER USE A WIRE BRUSH, STEEL SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS. Surfaces which are marred collect dirt more rapidly and become more difficult to clean. Marring also increases the possibility of corrosive attack. Refinishing may then be required.
TO REMOVE HEAT TINT: Darkened areas sometimes appear on stainless steel surfaces where the area has been subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the stainless steel and is not harmful. Heat tint can normally be removed by the foregoing, but tint which does not respond to this procedure calls for a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE™ scouring pads or a STAINLESS scouring pad in combination with a powdered cleanser. Heat tint action may be lessened by not applying or by reducing heat to equipment during slack periods.
All food contact surfaces must be thoroughly drained and flushed prior to cooking in the kettle.
CONTROL PANEL: The textured control panel should be cleaned with warm water and mild soap. Never use an abrasive cloth or steel wool. Never use cleaning solvents with a hydrocarbon base.

WARNING
In the event of main burner ignition failure, a 5 minute purge period must be observed prior to re-establishing ignition source.

Maintenance

NOTICE
Contact the factory, the factory representative or a local service company to perform maintenance and repairs.

WARNING
Disconnect the power supply to the appliance before cleaning or servicing.

Daily

1. Wash exposed cleanable areas.

Monthly

1. Blower wheel inlet and motor air vent should be cleansed if an accumulation of dust or lint is obvious.

Twice a Year (minimum)

1. Have an authorized service person clean and adjust the unit for maximum performance.
2. The unit venting system should be examined and cleaned.
3. Grease the screw jack tilt mechanism via the lubricating nipple. Use Petro-Canada type OG-2 or equivalent.

Safety Valve Maintenance and Testing

CAUTION

• Under normal operating conditions a “try lever test” should be performed every two months. Under severe service conditions, or if corrosion and/or deposits are noticed within the valve body, testing must be performed more often. A “try lever test” should also be performed at the end of any non-service period.
• Hot, high pressure fluid may be discharged from body drain and vent during “try lever” test. Care must be taken to avoid any bodily contact.
• High sound levels may be experienced during “try lever” test.
• Wear proper safety equipment and exercise extreme care!
• Test at, or near, half of the operating pressure by holding the test lever fully open for at least two seconds to flush the valve seat free of sediment and debris. Then release lever and allow the valve to snap shut.
• If lift lever does not activate, or there is no evidence of discharge, turn off equipment immediately and contact a licensed contractor or qualified service personnel.

Service

General

When any difficulty arises always check that the unit has been connected to the gas supply type and voltage for which it was supplied. This can be done by examining the serial plate on the lower right side of the unit. It will list the gas type and voltage for which the unit was manufactured.
Wiring diagrams for the unit are located in a small envelope affixed to the side panel of left hand console.

Adjustments

Thermostat

WARNING
Adjustments and service work may be performed only by a qualified technician who is experienced in, and knowledgeable with, the operation of commercial gas cooking equipment. To assure your confidence, contact your authorized service agency for reliable service, dependable advice or other assistance, and for genuine factory parts.

The thermostat adjustment should not be changed. Check the following before changing the thermostat.

1. With kettle cold, the pressure on the pressure gauge should read in the green vacuum zone (25 to 30 inches Hg vacuum).
   If not, see ‘Re-establishing Vacuum” section.

2. The pressure switch may be set too high or too low and causing the out of adjustment condition. A voltmeter should be used by a properly trained serviceman to determine if the pressure switch or thermostat is actually cycling the burners. If the pressure switch is found to be cycling the burners, see “Pressure Switch” section.
   After verifying that the pressure switch is set and operating properly, the thermostat may be adjusted using the set screw inside the stem. At maximum setting, the thermostat should cycle off at a gauge pressure reading of 30 psi. Turn set screw clockwise to decrease pressure and counterclockwise to increase pressure.

Pressure Switch
The pressure switch should not be adjusted until it is determined to be the cause of an operating pressure difficulty.
See “Thermostat” section to determine if the source of difficulty is the pressure switch or thermostat.

The major difficulties caused by pressure switch mis-adjustment are:

1. Pressure relief valve opening, pressure rises above 45 psi.
2. Pressure in kettle is less than 30 psi and burner is being shut down by pressure switch (not thermostat).
   The pressure switch is preset for proper operation from the factory. It is adjusted to the maximum pressure which will prevent the pressure relief valve from opening. During preheat to the maximum thermostat setting (275 °F), from either a cold condition or a lower temperature setting, the temperature may overshoot the thermostat setting and be shut down by the pressure switch. This is normal, however, after the kettle has cycled several times (empty) the thermostat will begin cycling the unit.

To Adjust Pressure Switch

1. To obtain access to the pressure switch, the front panel must be removed. Remove the screws on bottom of the panel. Be sure to support the panel to avoid excessive strain on the wiring.

2. To increase the pressure switch setting, turn the white ribbed knob clockwise; to decrease, turn it counterclockwise.
   Use the centre of the black ring as an indicator.

3. With the kettle empty and completely cold, turn kettle on and set thermostat to maximum setting (275 °F).

4. The pressure in kettle (read pressure gauge on front panel) should reach a maximum of 30 psi and pressure relief valve should not open. Kettle pressure may rise 3 or 4 psi even after burners shut down.

5. Relief valve should not open when kettle pressure is 45 psi; pressure switch setting is satisfactory.

6. If the safety relief valve opens, reduce setting on pressure switch, cool kettle completely by running cold water through it and repeat steps 3 – 6.

7. If pressure in kettle is below 30 psi increase setting of pressure switch, cool kettle completely by running cold water through it and repeat steps 3 – 7.

8. Allow the kettle to cycle several times to verify the correct pressure setting.

9. Replace the front panel when adjustment is complete.

Adding Water (Low Water Light Comes On)
It may be necessary to replenish water in the jacket when the low water indicator comes on. Do so as follows:

1. Unit should be completely cold and off.
2. Lift handle of pressure relief valve to release vacuum in kettle.
3. Remove relief valve and attach a 3/4” NPT elbow pointing upward.
4. Using pure distilled water only, pour the water into the open end of elbow (a funnel will be helpful). Water will enter kettle slowly, as air must escape through the same hole. Water should be added until water level at the sight glass is halfway between the minimum and maximum levels.
5. When sufficient water has been added, remove elbow and replace pressure relief valve. Be sure to seal threads with a pipe joint compound suitable for steam at 50 psi.
6. Vacuum must be re-established (See Re-establishing Vacuum).

FOR REFERENCE
The total amount of distilled water to be added when low level pilot is illuminated:

Re-Establishing Vacuum
Periodically check pressure gauge when kettle is cold. Reading should be in green vacuum zone (below 0 psi). Otherwise air is present and proper heating will not occur. Use the following procedure to remove air and re-establish vacuum:
With the kettle empty, turn the thermostat knob to the highest temperature. When the pressure gauge reaches 20 psi, turn thermostat off, open the pressure relief valve until pressure gauge reads 1 psi, then sharply release it. This should remove the air and restore performance of the kettle.
Should the kettle fail to maintain a vacuum after repeated attempts to establish vacuum, further checks should be made to see if the pressure relief valve is leaking or if there are any leaks in the pressure relief valve piping, copper lines going to the pressure switch, pressure gauge or th ermostat fitting.

• General advice: If potential for exposure exists refer to Section 8 for specific personal protective equipment.

• Inhalation: Move person to fresh air; if effects occur, consult a physician.

• Skin contact: Wash off with plenty of water.

• Eye contact: Flush eyes thoroughly with water for several minutes. Remove contact lenses after the initial 1-2 minutes and continue flushing for several additional minutes. If effects occur, consult a
  physician, preferably an ophthalmologist.

• Ingestion: No emergency medical treatment necessary.
  Most important symptoms and effects, both acute and delayed: Aside from the information found under Description of first aid measures (above) and Indication of immediate medical attention and
  special treatment needed (below), any additional important symptoms and effects are described in

• Section 11: Toxicology Information.
  Indication of any immediate medical attention and special treatment needed
  Notes to physician: No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.

FIREFIGHTING MEASURES

• Suitable extinguishing media: Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. Foam. Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective.

• Unsuitable extinguishing media: Do not use direct water stream. May spread fire.
  Special hazards arising from the substance or mixture

• Hazardous combustion products: During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating. Combustion products may include and are not limited to: Carbon monoxide. Carbon dioxide.

• Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation. Violent steam generation or eruption may occur upon application of direct water stream to hot liquids.

Advice for firefighters

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound from venting safety device or discoloration of the container. Burning liquids may be extinguished by dilution with water. Do not use direct water stream. May spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be moved by flushing with water to protect personnel and minimize property damage.
Special protective equipment for firefighters: Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots, and gloves). If protective equipment is not available or not used, fight fire from a protected location or safe distance.

ACCIDENTAL RELEASE MEASURES

• Personal precautions, protective equipment and emergency procedures: Keep unnecessary and unprotected personnel from entering the area. Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection.
• Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. See Section 12, Ecological Information.
• Methods and materials for containment and cleaning up: Small spills: Absorb with materials such as: Cat litter. Sawdust. Vermiculite. Zorb-all®. Collect in suitable and properly labeled containers.
• Large spills: Dike area to contain spill. See Section 13, Disposal Considerations, for additional information.
