Model

KTT-G and KTC-G models are stainless steel, steam-jacketed, table top mounted kettles
with a self-contained, gas heated steam source. The KTC has a crank tilt hand wheel,
and the KTT has a handle that allows the operator to manually tilt the kettle. The kettle
body is welded into one solid piece and furnished with a reinforced rim and welded­in “butterfly” shaped pouring lip. The interior of the kettle is polished to a 180 emery
grit finish, and the exterior is given a bright high buff finish. The unit is A.S.M.E. shop
inspected and registered with the National Board for a design pressure of 50 PSIG.

The self-contained steam source is heated by propane or natural gas and is
equipped with electronic ignition. Charged at the factory with chemically pure water
containing rust inhibitors, the steam source provides kettle temperatures of 150ºF to
approximately 295ºF.

Controls for the KTC unit include a crank tilt handwheel, thermostat, pressure gauge,
pressure relief valve, low water cut-off, On/Off switch, indicator lamp, gas regulator
valve, and water level sight glass. Controls for the KTT are the same as the above,
with the exception of the crank tilt hand wheel.

The gas supply shuts off automatically when the kettle is tilted.

The unit must be specified for use with natural gas or propane. For other gas types,
consult factory. Service connections are required for gas and 115V electricity.

5. To Transfer Product or Empty Kettle:

Crank Tilt Kettles:
The kettle body is tilted using the crank tilt handwheel. Turning the crank

clockwise tilts the kettle body; counter-clockwise returns it to an upright
position. The kettle body will remain in any tilted position.

Hand Tilt Kettles:
The kettle is designed to be tilted in a controlled manner. Grasp the

insulated plastic ball firmly. Maintain a firm grip on handle when tilting,
keeping kettle body in a tilted position or SLOWLY returning the kettle
body to an upright position.

6. Use of Common Accessories

Lift-Off Cover:
a. As with stock pot cooking, an optional lift off cover will speed up

the heating of water and food products. A cover helps retain heat
in the cooking vessel and reduces the amount of heat and humid­ity released into the kitchen. Use of a cover can reduce some
product cook times and help maintain the temperature, color and
texture of products being held or simmered for extended periods.

b. Make sure the plastic ball handle is secure on the lift off cover

before using. ALWAYS use the plastic handle to place or remove
cover from the kettle. Wear protective oven mitts and a protective
apron.

c. When putting the cover on the kettle, position it on top of kettle

rim, with its flat edge facing the pouring lip.

d. When removing cover:

1) Firmly grasp plastic handle

2) Lift rear edge (farthest from operator) 1-2” (3-5 cm) to
allow any steam and water vapor to escape the cooking
vessel. Wait 2-3 seconds.

3) Tilt cover to 45-60° angle and allow any hot condensate or
product to roll off cover back into kettle.

4) Remove cover, ensuring that any remaining hot condensate
or product does not drip on operator, floor or work surfaces.

5) Place cover on safe, flat, sanitary, out-of-the-way surface,
or return to kettle rim. Cover may also be placed in the
optional holder for cover as shown in the photograph on the
next page.

Operation

CAUTION

DO NOT OVER FILL THE KETTLE WHEN

COOKING, HOLDING OR CLEANING. KEEP
LIQUIDS AT A MINIMUM OF 2-3” (5-8 CM)
BELOW THE KETTLE BODY RIM TO ALLOW
CLEARANCE FOR STIRRING, BOILING AND

SAFE PRODUCT TRANSFER.

Basket Insert:
a. An optional kettle basket insert can assist in cooking water-boiled

products including eggs, potatoes, vegetables, shell fish, pasta and
rice. The nylon mesh liner must be used when cooking product
smaller than the mesh size of the basket, which is approximately
1/4” (6 mm). This includes rice and small pasta shapes.

b. Tips For Use:

1) Allow for the water displacement of the basket and product
to be cooked. This may mean only filling the kettle half full
of water. Test the basket and product displacement with the
kettle OFF, and with cold water in the kettle.

2) Load basket on a level, stable work surface.

3) Lift the loaded basket with both hands. Get help from
another person if the basket is too heavy for safe handling.
Then slowly lower product into kettle.

4) When removing basket with cooked product, lift basket
straight up, ensuring bottom of basket clears the rim and
pouring lip of the kettle. Wear protective oven mitts and
protective apron.

5) Allow hot water to fully drain from product, before moving
basket away from the kettle. Do not rest kettle basket on
kettle rim or pouring lip. If basket is too heavy for individual
to lift and safely move, get help from another person.
Remove product immediately from basket into another
container, being sure to avoid contact with hot product and
hot basket or place basket with food on stable, flat surface,
setting it inside a solid steamer or bake pan, to catch any
remaining hot water draining from product.

OM-KTT/KTC-G 11

Sequence of Operation

The following “action-reaction” outline is provided to help understand how the kettle
works.

1. When the power switch is turned on, it starts the spark igniter and opens the
automatic valve for the pilot burner. The spark ignites a pilot flame, which heats
the sensor. The sensor then sends a signal to turn off the spark. The flame
thereafter acts as a standing pilot until the power is turned off.

2. If the pilot flame is not sensed within 90 seconds after spark begins, a timer
shuts down the entire operation. To attempt a second trial for ignition, turn off
the power switch. Check the gas supply valves and wait five minutes before
trying again by switching power on. If you cannot establish a pilot flame in four
tries, close all valves, turn off the power, and contact an authorized Service
Agency.

3. When the operator sets a temperature on the thermostat, it causes the
automatic valve to admit gas to the main burner, where it is ignited by the pilot
flame. When the kettle reaches the set temperature, the thermostat switch
opens. This stops the signal to the gas control valve and shuts off gas to the
main burner. The pilot flame remains lit. When the kettle cools below the set
temperature, the thermostat switch closes and starts another cycle. On and
off cycling continues and maintains the kettle at the desired temperature. This
action is indicated by the Heat indicator light.

The kettle has the following safety features in addition to the 90-second ignition timer:

1. Low water cutoff relay that will shut off gas supplies to all burners until the
jacket water level is corrected.

2. High limit pressure switch, set to open at about 43 PSI and to shut down the
burners until jacket pressure is decreased.

3. Pop safety valve, which will release steam if jacket pressure exceeds 50 PSI.

4. Tilt switch, which shuts off all burners when the kettle is tilted.

5. Gas pressure regulator built into the gas control valve.

B. Precautions

Before cleaning, shut off the kettle by turning the thermostat dial to “OFF,” and

shut off all electric power to the unit at a remote switch, such as the circuit
breaker.

C. Procedure

1. Clean food-contact surfaces as soon as possible after use. If the unit is in
continuous use, thoroughly clean and sanitize the interior and exterior at
least once every 12 hours.

2. Scrape and flush out food residues. Be careful not to scratch the kettle
with metal implements.

3. Prepare a hot solution of the detergent/ cleaning compound as instructed
by the supplier. Clean the unit thoroughly. A cloth moistened with clean­ing solution can be used to clean controls, housings, and electrical
conduits.

4. Rinse the kettle thoroughly with hot water. Then drain completely.

5. As part of the daily cleaning program, clean all inside and outside sur­faces that may have been soiled. Remember to check such parts as the
underside of the cover, control housing, etc.

Use a brush, sponge, cloth, plastic or

rubber scraper, or plastic wool to clean.

Don’t use metal implements

or steel wool when cleaning.

6. To remove burned-on foods, use a brush, sponge, cloth, plastic or rubber
scraper, or plastic wool along with the cleaning solution. To reduce effort
required in washing, let the detergent solution sit in the kettle for a few
minutes and soak into the residue. Do NOT use abrasive materials or
metal tools that might scratch the surface. Scratches make the surface
harder to clean and provide places for bacteria to grow. Do not use steel
wool, which will leave particles in the surface and cause eventual corro­sion and pitting.

7. The outside of the unit may be cleaned with a warm water (100°F or
less) spray. Do not use a high pressure spray.

8. The outside of the unit may be polished with a recognized stainless steel

The pressure gauge

should show a

vacuum of 20 to 30

inches when the

kettle is cold.

NOTICE: Contact an authorized representative when repairs are required.

A Maintenance & Service Log is provided at the back of this manual. Each time
maintenance is performed on your kettle, enter the date on which the work was done,
what was done, and who did it. Keep this manual on file and available for operators to
use. Periodic inspection will minimize equipment down time and increase the efficiency
of operation. The following points should be checked:

A. Jacket Vacuum/Removing Air from Jacket (by Operator)

Every day, while the kettle is cold, read the pressure/ vacuum gauge. A positive

reading or a negative reading between zero and 20” vacuum on the pressure/
vacuum gauge indicates excess air in the jacket. Air in the jacket slows kettle
heating and can prevent the kettle from reaching operating temperature.

To remove air:

1. Start the unit. (See “Operation” section).

2. Make sure the elbow on the outlet of the pressure relief valve is turned so
that escaping steam is directed down toward the floor. Be sure and follow
the instructions on the attached pressure relief valve tag.

3. When the pressure/vacuum gauge reaches a positive pressure reading of
5 PSI, release trapped air by lifting the pressure relief valve ring for about
one second. Repeat this step, then let the valve ring snap closed, so the
valve will seat properly and not leak.

B. Pressure Relief Valve (by Operator)

At least twice a month, test the pressure relief valve. Test the valve with the

kettle operating at 15 PSI (105 kPa), by holding the test ring for at least five
seconds. Then release the ring and permit the valve to snap shut. If the ring does
not activate, if there is no discharge, or if the valve leaks, stop using the kettle
immediately and contact a authorized service representative.

C. Grease / Lubrication (by Service)

Hand Tilt Models: At least twice a year, grease the two trunnion bearings. The

bearings are located within the kettle support housing. Remove the access
panels from the support housing with a screwdriver to gain access to the
grease fittings. Use a lithium-based, multi-purpose grease. When the access
panels are removed, the mounting bolts for the trunnion bearings and tilt switch
can also be checked for tightness. When finished, reassemble access panels to
support housing.

Crank Tilt Models: The gear housing has been fitted for proper lubrication of

moving parts. Since the gears do not run in oil, periodic lubrication with grease
is essential. Frequency of lubrication depends on operating conditions, but
should occur at least once every six months. The use of a Number Two grade
LGI lithium grease is recommended. Add grease through the Zerk fittings on the
gear housing until grease flows out of the bearings around the trunnion shaft.
Place a liberal amount of grease on the gear to cover the arc that is in contact
with the worm gear.

TO AVOID INJURY, READ AND FOLLOW

ALL PRECAUTIONS STATED ON THE
LABEL OF THE WATER TREATMENT

COMPOUND.

WARNING

USE OF ANY REPLACEMENT PARTS OTHER

THAN THOSE SUPPLIED BY THE

MANUFACTURER OR THEIR AUTHORIZED

DISTRIBUTORS CAN CAUSE INJURY
TO THE OPERATOR AND DAMAGE TO
THE EQUIPMENT AND WILL VOID ALL

WARRANTIES.

CAUTION

INSURE ELECTRICAL POWER IS REMOVED

AND THE GAS IS TURNED OFF AT THE

SHUTOFF VALVE PRIOR TO PERFORMING

ANY MAINTENANCE ON THIS KETTLE.

WARNING

THIS KETTLE IS DESIGNED TO BE

WATER RESISTANT. FAILURE TO FOLLOW

PROPER MAINTENANCE PROCEDURES

MAY VOID THE WARRANTY.

D. Jacket Filling

Every day, before you turn on the unit, make sure the water level is

approximately in the center of the water gauge glass. The jacket was filled at
the factory with the proper amount of treated water, and is airtight, but over
time steam may be vented and water lost.

From time to time, you may need to restore the water to its proper level. The

procedure for adding water follows.

1. If you are replacing water lost as steam, use distilled water. Do not use tap
water. If you are replacing treated water that was drained from the jacket,
prepare more treated water as directed below.

2. Allow the kettle to cool completely. Remove the pipe plug from the jacket
fill assembly. Pour in the distilled or treated water. Using a funnel will help
you in this process. Hold the pressure relief valve open while you pour, to
let air escape from the jacket. Continue adding water until the water level
rises to the center of the round sight glass.

3. Air that gets into the jacket during the filling operation must be removed,
because it will make heating less efficient. Follow the procedure in Jacket
Vacuum/Removing Air From Jacket above, to restore a negative pressure
reading.

E. Water Treatment

1. Fill a mixing container with the amount of water required. Use only distilled
water.

The pressure relief valve and fill

plug are located directly behind the

pressure/vacuum gauge.

2. Hang a strip of pH test paper on the rim of the container, with about 1 inch
of the strip below the surface of the water.

3. Stir the water continuously, while you slowly add water treatment
compound until a color between indicating a pH of 10.5 and 11.5 is
reached. (Shown on the pH test kit chart.) Judge the pH by frequently
comparing the test strip with the color chart provided in the pH test kit. If
there is a problem distinguishing color, use a pH meter.

4. Use a measuring cup to add the compound so that you may record the
exact amount used.

5. The amount may be used again, if the same water sources and compound
are used in the future. However, it is best to check the pH each time
treated water is prepared.
