EQUIPMENT DESCRIPTION
AH/1 steam kettles are stainless steel, floor mounted kettles with a self-
contained steam source heated by gas. A closed steam jacket covers the lower
portion of the kettle. Heat from the gas burner boils water in the jacket to
produce steam under pressure. To ignite the burners, the kettle uses electronic
spark ignition.
The kettles are stationary (non-tilting). Liquids can be removed through the
tangent draw-off valve.
Exposed surfaces are stainless steel. Insulated sheathing protects the kettle
body, and a housing encloses the controls. Three tubular legs support the unit.
Bullet feet adjust to level the kettle.
A one piece dome cover is hinged to the kettle on the 20-gallon (75.7 liters)
model. Covers for 40 and 60-gallon (151.4 and 227 liters) kettles are supplied
with counterbalancing spring actuators to hold the covers in the fully open or
closed position.
Controls provided include the ON/OFF switch, to control electric power for the
unit, and the thermostat, to set the cooking temperature. The automatic controls
and a brief description of each are as follows.
1. Gas pressure regulator: Protects the unit from high pressure in the gas
supply line.
2. Automatic gas valves: Allow gas into the burners as needed.
3. Pressure switch: Turns off the burner when jacket pressure reaches 27 PSI
(186.1 kPa, 1.86 bars). Lights the burner when pressure drops to 22 PSI
(151.6 kPa, 1.52 bars).
4. Safety valve: Lets steam out of the jacket if the steam pressure exceeds 30
PSI (206.7 kPa, 2.06 bars).
5. Low-water cutoff: Turns off the burner if the water level in the jacket gets
too low for safe operation.
Instruments also are provided to show what is happening inside the unit. These are:
1. Water level sight glass: Indicates whether there is enough water in the
steam jacket.
2. Pressure/vacuum gauge: Shows steam pressure, and whether too much air
has entered the jacket.
3. Heating indicator light: Indicates that the kettle is being heated.
4. Power on indicator light: Glows when the unit is turned on.
5. Low water indicator light: Lights to show that jacket water needs to be
replenished.

The kettle body is welded into one piece and has a rim reinforced by a rectangular
bar. The interior and exterior of the kettle is polished to a 180 emery grit finish. The
unit is ASME shop inspected and registered with the National Board for working
pressures up to 30 PSI (206.7 kPa, 2.06 bars).
The standard 2 inch (50mm) tangent draw-off is a 316 stainless steel, compression
disc valve. A removable strainer with 1/4 inch (6.35 mm) holes keeps pieces of
product from entering the draw-off during cooking.
The jacket is filled at the factory with water containing rust inhibitors. The kettle
can operate at steam pressures up to 30 PSI (206.7 kPa, 2.06 bars), which provide
temperatures of 150°F (65°C) to approximately 270°F (135°C). This range allows
warming, simmering, boiling, or braising.
For the kettles, options include:
1. Larger 3 inch (76 mm) tangent draw-off
2. Solid disc strainer or strainer with 1/8” (3.18 mm) perforations

PERIODIC MAINTENANCE
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:
[BY OPERATOR]
1. Check the pressure/vacuum gauge every day. The gauge should show a
vacuum of -20 to -30 inches of mercury (Hg) vacuum or a range of -0.7 to
-1.0 Bar, see “Jacket Vacuum” in this manual.
2. Also check the jacket water level every day. It should be between the marks
on the gauge glass. If the level is low, see “Jacket Filling and Water Treatment”
in this manual.
3. Carefully test the pressure relief valve at least twice each month. With the
kettle operating at 15 psi (105 kPa, 1.1 bar),pull the test lever and let it
snap back to its closed position. If there is little discharge (mostly air), and
the pressure gauge drops back to 0 psi (0 kPa, 0 bar), allow the pressure to
build back to 5 psi (35 kPa, 0.34 bar) and repeat the procedure. (Tip: Using a
screwdriver or other implement to pull the ring will help you avoid contact with
the steam.
[BY SERVICE TECHNICIAN]
4. Electrical wiring should be kept securely connected and in good condition.
5. The inside of the support housing should be kept clean.
6. The gear housing has fittings for lubrication of moving parts. The gears do not
run in oil, so periodic lubrication with grease is necessary.
7. Frequency of lubrication depends on operating conditions, but it should be
done at least once every six months.
8. Use a #2 grade LGI lithium grease to add grease through Zerk fittings on gear
housing until it flows out of the bearings around the trunnion shaft.
9. Place liberal amounts of grease on the gear to cover the arc that is in contact
with the worm gear.
10. Keep electrical wiring and connections in good condition.
11. Keep the inside of the control console clean and dry.
JACKET VACUUM/REMOVING AIR FROM JACKET
When the kettle is cold, a positive pressure reading on the pressure/vacuum gauge
or a reading near 0 psi (0 kPa, 0 bar) indicates that there is air in the jacket. Air in
the jacket acts as an insulator, and slows kettle heating.
To remove air:
1. Start the unit. (Be sure there is water or product in the kettle when heating).
2. When the pressure/vacuum gauge reaches a positive pressure reading of 5 psi
(35 kPa, 0.34 bar), release the trapped air and steam by pulling up the safety
valve ring for about five seconds. Repeat this step three or four times. Then let
the pull ring snap back into the closed position.
3. If there is little discharge (mostly air), and the pressure gauge drops back to 0
psi (0 kPa, 0 bar), allow the pressure to build back to 5 psi (35 kPa, 0.34 bar)
and repeat the procedure.
4. Once steam has been vented from the jacket as described in b, above, remove
the hot water from the kettle and replace it with cold. This will condense steam
in the kettle jacket, and the pressure gauge should show -20 to -30 inches
of mercury (Hg) vacuum or a range of -0.7 to -1.0 Bar. If it does not, or if the
vacuum is leaking down, contact an authorized service agency to correct the
problem.
PRESSURE RELIEF VALVE
At least twice a month, test the pressure relief valve. Test the valve with the kettle
operating at 15 PSI (105 kPa, 1.1 bar), 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.
JACKET FILLING
The jacket was charged at the factory with the proper amount of treated water.
You may need to restore this water, either because it was lost as venting steam or
by draining. If you are replacing water lost as steam, use distilled water. If you are
replacing treated water that ran out of the jacket, prepare more treated water as
directed in “Water Treatment Procedure,” below.
1. Allow the kettle to cool completely. The procedure will be easier with the kettle
under vacuum (pressure gauge reading below zero).
2. Allow the kettle to cool completely. Remove the pressure gauge from the sight
glass 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. Position a funnel in the opening and fill it with properly treated water.
4. 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.
WATER TREATMENT
1. Obtain water treatment compound and a pH test kit from your authorized parts
distributor.
2. Fill a mixing container with the measured amount of water required. (See
table). Distilled water is recommended.
Kettle Model Jacket Capacity
EE-20 3-1/4 Gallons (12.3 liters)
EE-40 4-1/2 Gallons (17.0 liters)
3. Hang a strip of pH test paper on the rim of the container, with about 1” (2.54
cm) of the strip below the surface of the water.
4. Measure the water treatment compound (ones way to do this is to add the
compound from a measuring cup).
5. Stir the water continuously, while you slowly add water treatment compound,
until the water reaches a pH between 10.5 and 11.5. Judge the pH by
frequently comparing the test strip color with the color chart provided in the pH
test kit. If you are color blind use an electroanalytical instrument to measure
the pH level or have a person who is not color blind read the test strip color
level.
6. Record the exact amounts of water and treatment compound used. These
amounts 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.

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 stays lit.
4. When the kettle cools below the set temperature, the thermostat switch
closes and start 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 26 PSI and to shut down the
burners until jacket pressure is decreased.
3. Pressure relief safety valve, which will release steam if jacket pressure
exceeds 30 PSI.
4. Gas pressure regulator built into the gas control valve.
