EQUIPMENT DESCRIPTION
AH/1 steam kettles are stainless steel, floor mounted kettles with a selfcontained 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 model. Covers
for 40, 60, 80, and 100-gallon 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.

Brands. All Rights Reserved. Unified Brands is a wholly-owned subsidiary of Dover Corporation.
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.

Page 6
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 solution
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 (see picture at the beginning of this section).
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.
11. When the equipment needs to be sanitized, use a sanitizing solution equivalent
to one that supplies 200 parts per million chlorine. Obtain advice on the

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:
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.
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.)
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.
Allow the kettle to cool completely. The procedure will be easier with the kettle
under vacuum (pressure gauge reading below zero).
1. Make sure the fill (gate) valve is closed, and remove the square head pipe plug
with open-ended wrench or crescent wrench.
2. Position a funnel in the opening and fill it with properly treated water.
3. Slowly open the fill valve to allow water to be sucked into the jacket. Quickly
close the valve to prevent air from entering.
6 OM-AH/1E Domestic
Page 7
4. Check water level in the jacket to ensure that it is between minimum and
maximum marks on glass.
5. Close the valve and reinstall the square-head pipe plug.
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).
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.
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.
