1.0 INSTALLATION INSTRUCTIONS
Immediately after unpacking, check for possible shipping damage. If the kettle is found to
be damaged, save the packaging materials and contact the carrier within 15 days of
delivery.
1. The kettle must be installed in accordance with:
2. State and/or local codes.
3. In the USA, the National Electrical Code, ANSI/NFPA-70 (latest edition). In Canada,
the Canadian Electrical Code, Part 1, CSA Standard C22.1 (latest edition).
4. Position appliance on counter allowing sufficient rear clearance from wall to tilt freely
and completely without obstruction.
5. Mark four corner locations of appliance base.
6. Remove appliance from counter and locate position of 4 holes as per Figure 1. Drill
four 7/16" diameter holes.
7. Use 5/16-18 Hex Cap Screws with suitable flat washers to bolt down. Screw length
must be 1-1/4 long plus counter top thickness.
8. Apply a continuous bead of Silastic or other equivalent sealant along the complete
perimeter edge of the appliance base.
9. Wipe off excess sealant.
10. A Control Box with power supply equivalent to Electrical Rating of appliance should be
located conveniently nearby.

1.0 INSTALLATION INSTRUCTIONS (Continued)
WARNING: Disconnect electrical power supply and place a tag
at the disconnect switch to indicate you are on the circuit.
1. A waterproof electrical connection for power supply to console housing must be
provided.
2. Ground appliance to terminal provided inside console housing.
3. Turn power ON and check for proper operation.

2.0 INTRODUCTION
DESCRIPTION
Models KTG-6E (6 gallon capacity) and KTG-10E (10 gallon capacity) and KTG-12E (12
gallon capacity) electrically powered, self-contained, countertop, tilting kettles. Each model
has a jacket of double-wall construction forming a sealed reservoir around the lower two-
thirds of the kettle. The reservoir is charged with distilled water and anti-freeze solution.
Kettles are equipped with a removable electric heating element and controls, including a
low water cutoff device for protection of the heating element. All models are of identical
construction, except for kettle size and element heating capacity.
BASIC FUNCTION
Self-contained kettles operate by generating steam in the kettle reservoir. The sequence of
operation is as follows:
1. Operator turns the power switch to the ON position and sets the temperature control
dial to the desired setting from 1 to 10.
2. Control circuit is normally completed to the temperature controller if the following
conditions exist:
A. Water level in the kettle reservoir is adequate to prevent circuit interruption by the
low water cut off device. An activated cutoff is indicated by the amber low water
light turning on, and the heating element shut off.
B. Kettle is in vertical position with circuit completed through the tilt interlock switch.
3. Thermostat control contacts close to energize contactor coils.
4. Power is supplied to the elements through closed power contactors.
5. As the temperature of water rises in the kettle reservoir, increase in steam pressure is
indicated on the pressure gauge.
6. When the temperature of steam in the reservoir reaches the setting of the temperature
control dial, the temperature controller opens to break the contacts and shuts off the
heating element. The heating elements will cycle on and off as required to maintain
temperature setting.

3.0 OPERATING INSTRUCTIONS
WARNING: The safety relief valve may discharge large amounts of
steam and/or hot water. Keep away from the discharge tube at all
times. Warn others in the area so they will not be startled by the
sound.
1. Ensure that the external electrical shut-off to the kettle is on.
2. Check pressure gauge for correct cold kettle reading. Reading should be in the green
vacuum zone. If reading is not in the vacuum zone, follow VENTING INSTRUCTIONS
prior to using the kettle.
3. Place power switch in ON position.
4. Preheat the kettle by placing thermostat knob at ‘10' and wait until TEMPERATURE
light goes off.
5. Add food to be cooked into the kettle.
6. Place thermostat knob at required temperature setting from 1 to 10 coinciding with a
temperature range from roughly 90EF to 289EF (32EC to 143EC, jacket temperature.)
Approximate cooking temperatures with water at various thermostat settings are as
follows:
APPROXIMATE TEMPERATURE (JACKET)

5 125E52E
6 160E41E
7 195E91E
8 231E110E
9 273E134E
10 289E143E
NOTE: Preheating should not be used when cooking milk and egg food
products which adhere to hot cooking surfaces. These foods should be
placed into kettle before heating is begun.

3.0 OPERATING INSTRUCTIONS (Continued)
7. When cooking is finished set thermostat knob and power switch to the OFF position.
8. Pour finished product from kettle using tilt handle. Be careful to avoid splashing.
9. Add water to kettle for cleaning purposes.
10. Wash kettle thoroughly. See CLEANING procedure.
TILTING INSTRUCTIONS
DO NOT ATTEMPT TO TILT WITH LID ON KETTLE.
1. To empty contents, turn handwheel counterclockwise to desired position.
2. To return kettle to cooking position, turn handwheel clockwise until in upright position.
NOTE: When kettle is tilted a safety switch will automatically turn off the
power supply. The kettle will not operate once the kettle has been tilted.

4.0 CLEANING INSTRUCTIONS
WARNING: Disconnect the power supply to the appliance before
cleaning or servicing.
The kettle interior and exterior should be thoroughly washed after each use in preparation
of a different food.
1. Add water and mild detergent to the kettle immediately after use.
2. Scrub kettle interior with nylon brush.
3. Loosen food which is stuck to kettle by allowing it to soak at a low temperature setting.
4. Rinse with clear water and dry.
WARNING: Do not hose down appliance under any condition.
Failure to comply will void warranty.
5. Wipe down exterior, rinse and dry.
CAUTION: Do not use cleaning agents that are corrosive.
Use of cleaning agents that contain chloride, acids or salts are corrosive and may cause
pitting and corrosion when used over a period of time; this will reduce the life of the
appliance.
Should pitting or corrosion occur this is not covered by warranty.
Follow the recommended cleaning instructions. Use a mild detergent, warm water and
rinse thoroughly.
NOTE: Never scrape the inside of the kettle with metal tools, steel scouring
pads, or abrasive cleaners. Scratches will result which will spoil the kettle’s
general appearance and make it harder to clean and maintain a sanitary
condition.
