Equipment Description
Groen AHS steam kettles are stainless steel, floor mounted kettles with a self-contained steam source heated by gas. A closed steam jacket covers the lower
b of the kettle. Heat from the gas burner boils
water in the jacket to produce steam under pressure. To ignite the burners, Model AHS 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 AHS. Covers for 40 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.
a. Gas pressure regulator: Protects the unit from
high pressure in the gas supply line
b. Automatic gas valves: Allow gas into the
burners as needed
c. Pressure limit switch: Turns off the burner when
jacket pressure reaches 27 PSI. Lights the burner when pressure drops to 22 PSI.
d. Safety valve: Lets steam out of the jacket if the
steam pressure exceeds 30 PSI.
e. 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:
a. Water level sight glass: Indicates whether there
is enough water in the steam jacket.
b. Pressure/vacuum gauge: Shows steam
pressure, and whether too much air has entered the jacket.
c. Heating indicator light: Indicates that the kettle
is being heated.
d. Power on indicator light: Glows when the unit is
turned on.
e. 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.
The standard 2 inch tangent draw-off is a 316 stainless steel, compression disc valve. A removable strainer with ¼ inch 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, which provide temperatures of 150ºF (65ºC) to approximately 250ºF (121ºC). This range allows warming, simmering, boiling, or braising.

Use of Common Accessories
1. Basket Insert
An optional kettle basket insert set (Tri-BC) will assist in cooking water-boiled products including eggs, potatoes, vegetables, shell fish, pasta and rice. The nylon mesh liners 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.
Tips for Use
1) Allow for water displacement by the baskets 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.
CAUTION DO NOT OVERFILL THE KETTLE WHEN COOKING, HOLDING OR CLEANING. KEEP LIQUIDS A MINIMUM OF 2-3” (5-8 cm) BELOW THE RIM TO ALLOW FOR STIRRING, BOILING AND SAFE PRODUCT TRANSFER.
2) Load baskets on a level, stable work surface.

before moving basket away from the kettle.
Sequence of Operation
7) 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.
8) 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.
The following “action-reaction” outline is provided to help understand how the AHS 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 Groen 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 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 26 PSI and to shut down the burners until jacket pressure is decreased.
3. Pop safety valve, which will release steam if jacket pressure exceeds 30 PSI.
4. Gas pressure regulator built into the gas control valve.

Maintenance
NOTICE: Contact Groen or an authorized Groen Service Representative when repairs are required.
A Service Log is provided at the rear of this manual. Each time service is performed on this Groen equipment, enter the date on which the work was done, and who did it. Keep this manual with the equipment.
Periodic inspection will minimize equipment down time and increase the effiency of operation. The following points should be checked:
1. Jacket Vacuum/Removing Air from Jacket
When the kettle is cold, a positive pressure/ vacuum gauge reading 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.
12
To remove air:
a. Start the unit. (Be sure there is water or product
in the kettle when heating).
b. When the pressure/vacuum gauge reaches a
positive pressure reading of five PSI, 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.
c. If there is little discharge (mostly air), and the
pressure gauge drops back to zero PSI, allow the pressure to build back to five PSI and repeat the procedure.
d. Once steam has been vented from the jacket
as described in b, 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 a Groen authorized service agency.
WARNING AVOID ANY EXPOSURE TO THE STEAM BLOWING OUT OF THE SAFETY VALVE. SEVERE BURNS
CAN RESULT ON EXPOSED SKIN.
FAILURE TO CHECK PRESSURE RELIEF VALVE OPERATION PERIODICALLY COULD RESULT IN PERSONAL INJURY AND/OR DAMAGE TO EQUIP- MENT.
WHEN TESTING, AVOID ANY EXPOSURE TO THE STEAM BLOWING OUT OF THE SAFETY VALVE. DIRECT CONTACT COULD RESULT IN SEVERE BURNS.

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
2. Test Pressure Relief Valve
Carefully test the pressure relief valve at least twice each month. Wth the kettle operating at five 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 zero PSI, allow the pressure to build back to five PSI and repeat the procedure. (Tip: Using a screwdriver or other implement to pull the ring will help you avoid contact with the steam.
If the valve doe not activate, or there is no evidence
of discharge, or the valve leaks, stop using the kettle and contact a qualified Groen service representative.
3. Jacket Filling
Every day, before you turn on the unit, make sure the water level is approximately in the center
water to its proper level.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.
Allow the kettle to cool completely. The procedure will be easier with the kettle under vacuum ( pressure gauge reading below zero).
a. Make sure the fill (gate) valve is closed, and
remove the square head pipe plug with open­ended wrench or crescent wrench.
b. Position a funnel in the opening and fill it with
properly treated water.
c. Slowly open the fill valve to allow water to be
sucked into the jacket. Quickly close the valve to prevent air from entering.
13
OM-AHS
d. Check water level in the jacket to ensure that it
is between minimum and maximum marks on glass.
e. Close the valve and reinstall the square-head
pipe plug.
f. Reestablish the jacket vacuum as described in
Paragraph 2, above, if the pressure gauge does not show a negative reading of 20 to 30 inches mercury (Hg).
4. Water Treatment
TO AVOID INJURY, READ AND FOLLOW ALL PRECAUTIONS STATED ON THE LABEL OF THE WATER TREATMENT COMPOUND.
a. Obtain water treatment compound and a pH
test kit from your Groen Service Agent.
b. Fill a mixing container with the measured amount
of water required. (See table) Distilled water is recommended.
c. Hang a strip of pH test paper on the rim of the
the container, with about 1 inch of the strip below the surface of the water.
d. Measure the water treatment compound. One
way to do this is to add the compound from a measuring cup.
e. Stir the water continuously, while you slowly add
treatment compound, until the water has 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 test kit. Caution: Do not add excess amount of treatment compound. Excess amount could cause extensive corrosion.

5. Component Replacement
WARNING BEFORE REPLACING ANY PARTS, DISCONNECT THE UNIT FROM THE ELECTRIC POWER SUPPLY AND CLOSE THE MAIN GAS VALVE. ALLOW FIVE MINUTES FOR UNBURNED GAS TO VENT.
When component replacement involves breaking a gas pipe connection, check the new connection with soap solution or an appropriate leak detector. DO
NOT USE A FLAME TO TEST FOR LEAKS.
Internal wiring is marked as shown on the circuit schematic drawings (inside control housing and in this manual). Be sure that new cmponents are wired in the same manner as old components. An examination of the the circuit schematic shows that the safety componenets are wired in series. In most cases, a faulty component may be isolated with a jumper wire to verify that the component is faulty. If this determination is made, contact a certified Groen Service Agency for assistance.
Your Groen kettle is designed to operate smoothly and efficiently if properly maintained. However, the following is a list of checks to make in the event of a problem. Wiring diagrams are furnished inside the service panel and in this manual.
