AH-30 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 kettle is 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.
The cover for the 30-gallon kettle is equipped with a counterbalancing spring actuator
that holds the cover in either 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 limit switch: Turns off the burner when jacket pressure reaches 27 PSI.
Lights the burner when pressure drops to 22 PSI.
4. Safety valve: Lets steam out of the jacket if the steam pressure exceeds 30 PSI.
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.

water draining from product.

OM-AH-30 13
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.

14 OM-AH-30
Cleaning
A. Suggested Cleaning Supplies
1. A high quality detergent and sanitizer, or a combination cleaning-
sanitizing agent.
2. Kettle brushes in good condition.
3. Spray Degreaser.
4. De-limer/De-scaler.
5. A high quality stainless steel cleaner.
B. Precautions
Before any cleaning operation, shut off the kettle by turning the thermostat dial
to “OFF”, the ON/OFF switch 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, preferably while
the kettle is still warm. If the unit is in continuous use, clean and sanitize
inside and outside at least once every 24 hours.
2. Scrape and flush out large amounts of food residues. Be careful not to
scratch the kettle with metal implements. Close the draw-off.
3. Prepare a solution of the detergent/cleaning compound as instructed by the
supplier. Clean the unit thoroughly. A cloth moistened with cleaning solu-
tion can be used to clean controls, housing, electrical conduit, etc.
4. Rinse the kettle thoroughly with hot water. Then drain completely.
5. Disassemble the tangent draw-off valve. Clean the draw-off port and each
valve part with a brush.
6. Rinse the kettle and draw-off valve parts thoroughly with hot water, then
drain completely.
7. When you reassemble the draw-off valve, HAND-TIGHTEN the nut which
holds it in place.
8. As part of the daily cleaning program, clean soiled external and internal
surfaces. Remember to check the sides of the unit and control housing.
9. 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.
10. The outside of the unit may be polished with a recognized stainless steel
cleaner.

A. Jacket Vacuum/Removing Air from Jacket
When the kettle is cold, a positive pressure reading on the pressure/vacuum gauge
or a reading near zero 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, release the trapped air and steam by pulling up or out on the safety
valve lever or ring for about 1 second. Repeat this step, then let the pull ring
or valve lever snap back into the closed position.
3. If there is little discharge (mostly air), and the pressure gauge drops back to 0
PSI, allow the pressure to build back to 5 PSI and repeat the procedure.
4. Once steam has been vented from the jacket as described in 2, 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 a reading of 20 to 30 inches
mercury (Hg) below zero. If it does not, or if the vacuum is leaking down,
contact an authorized service agency.
B. Test Pressure Relief Safety Valve
Test the pressure relief safety valve at least twice each month. With the kettle
operating at 5 PSI (105 kPa), 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, allow the pressure to build back to 5 PSI and repeat the procedure. (Tip:
Using a will screwdriver or other implement to pull the ring help you avoid contact
with the steam.)
C. 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 air-tight, but over time steam may be vented
and water lost.
From time to time, you may need to restore the water to its proper lever 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 on next
page.
WARNING
WHEN USING THE EQUIPMENT OR
TESTING, AVOID ANY EXPOSURE TO THE
STEAM BLOWING OUT OF THE SAFETY
VALVE. SEVERE BURNS CAN RESULT
ON EXPOSED SKIN. FAILURE TO CHECK
SAFETY VALVE OPERATION PERIODICALLY
COULD RESULT IN PERSONAL INJURY
AND/OR DAMAGE TO EQUIPMENT.

jacket, prepare more treated water as directed in Water Treatment Procedure on next
page.
Allow the kettle to cool completely. The procedure will be easier with the kettle
under vacuum (pressure gauge reading below zero).
1. Remove pressure gauge with open-ended wrench or cresent wrench.
2. Position a funnel in the opening and fill it with properly treated water.
3. Pull the pressure relief while filling to allow water to be sucked into the jacket
and air to vent.
4. Check water level in the jacket to ensure that it is between minimum and
maximum marks on glass.
5. Apply teflon tape to pressure gauge threads in a clockwise pattern, then install.
6. Reestablish the jacket vacuum as described above. If the pressure gauge does
not show a negative reading of 20 to 30 inches mercury (Hg).
D. Water Treatment
1. Fill a mixing container with the amount of water required. Use only distilled water.
2. Following instructions apply to Water Treatment Kit.
a. 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.
b. 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 kit.
c. Use a measuring cup to add the compound so that you may record the
exact amount used.
d. 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.
WARNING
TO AVOID INJURY, READ AND FOLLOW ALL
PRECAUTIONS STATED ON THE LABEL OF
THE WATER TREATMENT COMPOUND.
