Self-Generating Steam Jacketed Kettles
Description
All electrically powered kettles described and referred to in this manual are pressure vessels of a double-wall construction
forming a sealed jacket (chamber) enveloping the lower two thirds of the kettle bowl surface.
The kettle bowl is the container for the food product which ideally should be a liquid or semi-liquid consistency to achieve complete
contact with the bowl surface and thus fully absorb the heat transmitted through that surface from the pressurized steam generated
in the kettle jacket.
The jacket is intended to function as a self contained sealed chamber with a permanent solution of water and antifreeze sucient not only to
immerse and thereby protect replaceable electric heating elements, but also provide the steam source during the steam generating process.
The heating elements are thermostatically dial controlled to provide precise temperatures throughout the range from slow
simmer to rolling boil.
All stationary kettles are intended to be permanently oor mounted on legs with adjustable anged feet (EL models) or
pedestals (EP models).
All kettles are equipped with a hinged counterbalanced stainless steel lid covering the kettle bowl opening, a sanitary stainless steel
tangent draw-o valve for the removal of the food product from the kettle bowl, and a safety relief valve plumbed to the kettle jacket.
Capacities
All models are suxed with either - 20, - 25, - 30, - 40, - 60, - 80 or -100 to indicate the capacity of that kettle in US gallons. Thus
an KELS-40 indicates a two thirds jacketed electrically powered steam kettle mounted on legs with a capacity of 40 US gallons.
Functioning Mode
All electrically powered self steam generating kettles consist of a jacket charged with a solution of water and antifreeze sucient to
completely immerse and protect replaceable electric heating elements.
To minimize tampering, the Safety Valve is plumbed toward the rear of the kettle jacket. Should any component malfunction and
cause the pressure in the jacket to reach the rated pressure of the kettle, this protective device will open automatically and release
excessive pressurized steam.
When the Power Switch is turned ON and the Temperature Control (Thermostat) Knob dialed simultaneously, TEMPERATURE pilot light will
come on and contactors will close to allow power to elements. Steam generation will commence and continue until the water contained in the
jacket reaches the thermostatic temperature, manually preselected, at which point the Temperature (thermostat) Control will de-energize and
open the contactors cutting o power to heating elements and TEMPERATURE pilot light will go o. When the temperature of the water in
the jacket drops slightly, the cycle will repeat itself thus making it possible to maintain any selected precise cooking mode temperature.
The temperature required for the cooking process to function adequately must be greater than the boiling point of the liquid food
product. Further, the higher the temperature, the greater the steam pressure attained in the jacket and consequently the quicker
the cooking process. For example, steam pressurized at 30 p.s.i. attains a temperature of 274º Fahrenheit.
Since air is an unsuitable media through which heat may be transferred, it has been removed from the kettle jacket during
testing at factory. The Pressure Gauge should indicate vacuum in the jacket, in the green vacuum zone on the gauge
(approximately 25 - 30 inches Hg), when the kettle is cold or has been inoperative for some time. The kettle jacket is intended
to function at all times as a completely sealed self-contained chamber and it is especially advisable not to trip the safety relief
valve during inoperative periods since this will break the vacuum seal and allow air to enter the kettle jacket.
It should be noted that Temperature Controls (thermostats) used on these particular kettles have an ultimate high limit temperature
and this setting will prevent the heating elements from ever generating steam pressure to reach or exceed the rated working
pressure of these kettles. Further should the Temperature Control fail, an unlikely condition, and consequently the circuit to the
heating elements remain energized, the Safety Valve will blow and release steam (i.e., water) from the self contained sealed kettle
jacket and consequently lower the water level in the jacket. A Safety Probe is incorporated in the circuit to sense depletion of the
water level in the kettle jacket and will not only activate the LOW WATER level indicator pilot light but also signal the Liquid Level
Control to switch o power and de-energize the circuit to the heating elements (preventing element burn outs) until the water level
is adequately replenished.

Disconnect the power supply to the appliance before cleaning or servicing.
Your kettle should be cleaned immediately after each use or when cooking a dierent 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-o 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
Never spray water into electric controls or components!
CAUTION
Do not use cleaning agents that are corrosive.
WARNING
The equipment and its parts are hot. Use care when operating, cleaning and servicing.
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. Turn the large hex nut on the draw-o valve counterclockwise until it is completely disengaged from the threads.
Grasp the valve knob and slowly pull out the valve stem. Wash the valve stem, disk and handle. Insert a nylon brush,
wet with detergent and water, into the valve body and tangent draw-o 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-o valve open when the kettle is not in use.
Cleaning
NOTICE
Draw-o 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.

Dairy Draw-Off Valve Cleaning
1. Remove the plug by rst 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 nished 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.
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 aected 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 aected.
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 nish 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 nish. 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 dicult to clean. Marring also increases the possibility of corrosive attack. Renishing 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 ushed 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.

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.
CAUTION
Hot, high pressure uid may be discharged from body drain and vent during “try lever” test. Care must be taken
to avoid any bodily contact.
CAUTION
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
ush the valve seat free of sediment and debris. Then release lever and permit the valve to snap shut.
If lift lever does not activate, or there is no evidence of discharge, turn o equipment immediately and contact a
licensed contractor or qualied service personnel.

Low Water Level
Proper water level must be maintained within the jacket for the kettle to operate. Depletion of water may occur from
excessive opening of or leakage through the safety relief valve.
If water is below required operating level, either initially at start-up or during use, the kettle will automatically shut o and
the LOW WATER signal light will come on.
In order for the kettle to operate, the following procedure must be followed:
The kettle must be cool before proceeding with the following steps.
1. Trip the safety relief valve lever to relieve all pressure from the kettle jacket.
2. At exterior rear of kettle jacket remove nut from Air Vent.
3. Insert funnel into Air Vent opening and slowly add the indicated amount of clean water for:
MODEL ADD: IF COMPLETELY EMPTY, ADD:
KELS-20, KELS-25, KEPS-20, KEPS-25 140 ounces 4.14 litres 376 ounces 11.12 litres
KELS-30, KEPS-30 150 ounces 4.44 litres 504 ounces 14.90 litres
KELS-40, KEPS-40 220 ounces 6.50 litres 548 ounces 16.20 litres
KELS-60, KEPS-60 250 ounces 7.39 litres 586 ounces 17.33 litres
KELS-80, KEPS-80 340 ounces 10.05 litres 850 ounces 25.12 litres
KELS-100, KEPS-100 420 ounces 12.42 litres 1088 ounces 32.17 litres
4. Replace air vent nut.
5. Follow AIR VENTING INSTRUCTIONS listed (9.5).
6. Continue normal operating procedure of kettle.
Extremely Slow Cooking Time
If the cooking time is abnormally slow, then the diculty may be due to air being present in the kettle jacket. To remove air,
follow AIR VENTING INSTRUCTIONS.
If the kettle will not reach and maintain Pressure Gauge zone in the green area on the gauge when cold, a slow leak
may have developed in the jacket. Check all tting connections to jacket including the heating element gasket. Tighten or
replace if necessary.
Slow cooking time may also be due to a burnt out heating element. Test elements and if defective, replace complete
element assembly.
Kettle Will Not Operate When Turned On
Check that power supply is available to kettle.
Kettle will not operate if water level is inadequate in jacket. Follow 9.1 LOW WATER LEVEL instructions.
Also check for defective power switch or loose wire connections.
Initially, when Thermostat Knob is dialed and TEMPERATURE indicator light does not come on, then it may be assumed
that malfunction is due to either a defective Thermostat or loose wiring connection(s). If TEMPERATURE indicator light
comes on when Thermostat Knob is dialed fully (i.e. setting of ‘10’), then eventually the kettle should read its maximum
temperature (290F) in the jacket and a corresponding pressure reading of approximately 40 psi should be evident on the
Pressure Gauge (on kettles rated at 50 psi).
Finally, when the kettle is turned ON and Thermostat Knob dialed, check that the Contactors are being energized and
power is being made available to the heating elements. Replace defective Contactors.

Draw-Off Valve Leaks
If leak occurs through the valve stem, replace the “O” ring. If the leak can be attributed to faulty sealing occurring between
the stem disc and valve seat, then this may be due to dried on food residue. Clean the dried on food residue with an
extremely ne emery cloth. If the rubber vulcanized stem piece has been damaged it must be replaced.
NOTICE
Draw-o 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.
VENTING INSTRUCTIONS
Check vacuum/pressure gauge when the kettle is cold. Gauge should be in the green vacuum zone. If not, air must
be vented (removed) for proper heating. Use the following procedures to vent air.
1. With the kettle empty, place power switch in ON position.
2. Set temperature control thermostat to ‘10’. Heat kettle until indicator light goes o.
3. Using a 7/16” wrench, open bleed vent one full turn for 10 seconds and then close.
WARNING
SCALD HAZARD
Live steam will escape the bleed nut when opened.
Stay clear of live steam when performing this operation.
4. Cool kettle. Check for proper vacuum in green vacuum zone. If reading is not low enough, repeat entire
procedure, steps 1 - 4.
NOTICE
Draw-o 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.
