b. It is important that the tip of the core probe be placed correctly into

the product since only the tip of the core probe senses the product
temperature. Do this by inserting the core probe halfway into the product,
positioning the tip at the center of the food mass, avoiding any bones.
If placing into a semi-liquid or liquid product, occasionally stirring the
product will ensure an accurate core probe reading. Do not let the core
probe tip touch the edges, bottom or side of the unit.

c.

If the core probe is not plugged into the receptacle when either the AUTO C2T
or MANUAL C2T button is pressed then an audible alarm along with a core
probe error message will notify the user that attention is required. Simply
plug the core probe into the receptacle and continue with the input process.

d. If the core probe is unplugged from the receptacle during the cooking

process or while in Hold Mode an audible alarm along with a core probe
error message will notify the user that attention is required. Simply plug
the core probe back into the receptacle and the cook process or Hold
Mode will continue.

e. While the core probe is not in use ensure the sealing cap is properly

protecting the panel mount connector. Failure to properly use the sealing
cap could result in damage to the unit.

OPERATING PROCEDURE

1. To Start Kettle Heating:

a. EVERY DAY make sure that the jacket water level in the middle of the sight

glass. If the level is too low, see “Jacket Filling and Water Treatment” in
this manual.

b. Check the pressure/vacuum gauge. If the gauge does not show 20 to

30 inches of mercury (Hg) vacuum (that is a reading of 20 to 30 below 0
atmospheric pressure), see “Jacket Vacuum” in this manual.

c. DO NOT attempt to light any burner with a flame.

d. Open the main supply gas valve (handle in line with the pipe).

e. Turn the switch to ON.

f. Set heat using instructions above.

2. To Stop Kettle Heating:

a. Turn the switch OFF.

b. Turn the manual gas valve OFF (handle a right angle to gas line).

c. Disconnect the units electrical power.

3. To Relight Kettle:

a. Close main gas supply valve.

b. Set on-off switch to OFF.

c. Wait five minutes, then proceed as directed under To Start Kettle Heating.

4. If electric power fails, do not attempt to operate the unit. When power is
restored, proceed as directed in To Start Kettle Heating.

5. To Transfer Product or Empty Kettle:

a. To tilt the body of the kettle forward, turn the hand crank on the front of the

cabinet counter-clockwise. The body will stay in the position it holds when
you stop cranking. To return the kettle body to its upright position, turn the
crank clockwise.

b. Product may also be transferred by means of the optional draw-off valve,

if the kettle is so equipped.

USE OF COMMON ACCESSORIES

1. Lift-Off or Counterbalanced Cover:

a. As with stock pot cooking, an optional cover can speed up the heating of

water and food products. It helps retain heat and reduces the heat and
humidity in the kitchen. A cover can reduce some product cook times
and help maintain the temperature, color and texture of products held or
simmered for longer periods.

b. Be sure the handle is secure on the lift-off cover before using. ALWAYS use

the handle to place or remove cover from the kettle. Wear protective oven
mitts and apron.

c. When putting the cover on the kettle, position it on top of kettle rim, with

its flat edge facing the pouring lip.

d. When removing cover:

1) Firmly grasp plastic handle.

2) Lift rear edge (farthest from operator) 1-2” (3-5 cm) to allow any steam
and water vapor to escape the cooking vessel. Wait 2-3 seconds.

3) Tilt cover to 45-60° angle and allow any hot condensate or product to
roll off cover back into kettle.

4) Remove cover, ensuring that any remaining hot condensate or product
does not drip on operator, floor or work surfaces.

5) Place cover on safe, flat, sanitary, out-of-the-way surface, or return to
kettle rim.

2. Basket Insert:

a. An optional kettle basket insert can assist in cooking water-boiled

The nylon mesh liner 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.

b. Tips For Use:

1) Allow for the water displacement of the basket 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.

2) Load basket on a level, stable work surface.

3) Lift the loaded basket with both hands. Get help from another person
if the basket is too heavy for safe handling. Then slowly lower product
into kettle.

4) When removing basket with cooked product, lift basket straight up,
ensuring bottom of basket clears the rim and pouring lip of the kettle.
Wear protective oven mitts and protective apron.

5) Allow hot water to fully drain from product, before moving basket
away from the kettle. Do not rest kettle basket on kettle rim or pouring
lip. 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 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.

or steel wool when cleaning.

PRECAUTIONS

Before cleaning, shut off the kettle by turning the main power switch to “OFF,” and
shut off all electric power to the unit at a remote switch, such as the circuit breaker.

PROCEDURE

1. Clean food-contact surfaces as soon as possible after use. If the unit is in
continuous use, thoroughly clean and sanitize the interior and exterior at least
once every 12 hours.

2. Scrape and flush out food residues. Be careful not to scratch the kettle with
metal implements. (For DHT models only: After flushing the kettle, close the
draw-off valve.)

3. Prepare a hot 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, housings, and electrical conduits.

4. Model DHT only: Disassemble the tangent draw-off valve. Clean the draw-off
port and each valve part with a brush.

5. Rinse the kettle and draw-off valve parts thoroughly with hot water, then drain
completely.

6. As part of the daily cleaning program, clean soiled external and internal
surfaces. Remember to check the sides of the unit and control housing,
underside of cover, etc.

7. To remove burnt on foods, use a brush, sponge, cloth, plastic or rubber scraper,
or plastic wool with the cleaning solution. To reduce effort required in washing,
let the detergent solution sit in the kettle 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 may leave particles in the surface and cause
eventual corrosion and pitting.

8. The outside of the unit may be cleaned with a warm water (100°F or less)
spray. Do not use a high pressure spray.

9. The outside of the unit may be polished with a stainless steel cleaner such as

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:

30 inches when the kettle is cold.

Add grease through Zerk Fittings.

The open end of the pressure relief valve

elbow must face downward.

Liberally grease the wheel where

it contacts the worm gear.

Test the safety valve at least twice monthly.

1. Check the pressure/vacuum gauge every day. The gauge should show a
vacuum of 20 to 30 inches mercury (Hg), when the kettle is cold. If it does not,
see “Jacket Vacuum” in this manual.

2. Also check the jacket water level every day. It should be in the middle of the
sight 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 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.)

4. If the valve does not activate, or there is no evidence of discharge, or the
valve leaks, stop using the kettle and contact a qualified Groen service
representative.

5. Keep the primary burner gas jet air inlets free of dust and lint.

6. The pilot flame should be blue. It should envelop about ½ inch (12 mm) of the
flame sensor tip.

7. The gear housing has fittings for lubrication of moving parts. The gears do not
run in oil, so periodic lubrication with grease is necessary.

8. Frequency of lubrication depends on operating conditions, but it should be
done at least once every six months.

9. 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.

10. Place liberal amounts of grease on the gear to cover the arc that is in contact
with the worm gear.

11. Keep electrical wiring and connections in good condition.

12. Keep the inside of the control console clean and dry.

13. Keep burner slots clean.

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 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.

3. 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.

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 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 to correct the problem.

JACKET FILLING AND WATER TREATMENT

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. Make sure the fill valve is closed, and remove the square head pipe plug with
open-ended wrench.

3. Position a funnel in the opening and fill it with properly treated water.

8 OM-DH(T)-20/40/60/80 (C,A,C2T™) Domestic

4. Slowly open the fill valve to allow water to be sucked into the jacket. Quickly
close the valve to prevent air from entering.

5. Check water level in the jacket to ensure that it is between minimum and
maximum marks on glass or at the top of the sight glass port for models DH/
DHT-80.

6. Close the valve and reinstall the squarehead pipe plug.

7. 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 PROCEDURE

1.

Obtain water treatment compound and a pH test kit from your Groen Service Agent.

2. Fill a mixing container with the measured amount of water required. Use only
distilled water.

Model Recommended Jacket Fill

DH-20, DHT-20 (C,A,C2T) 1-3/4 gallons

DH/1-40, DHT/1-40 (C,A,C2T) 1-1/2 gallons

DH-60, DHT-60 (C,A,C2T) 3 gallons

DH-80, DHT-80 (C,A,C2T) 3 gallons

3. 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.

4. Measure the water treatment compound. One way to do this is to add the
compound from a measuring cup.

5. 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.

6. As you add water to the jacket, check water level to ensure that it is between
minimum and maximum marks on glass or at the top of the sight glass port for
models DH/DHT-80 (see photo on page 8). Stop adding water when it reaches
the maximum marker on the gauge.

7. Record the exact amounts of water and treatment compound needed. These
amounts may be used again, if the same water sources and compound are
used. However, it is best to check the pH each time treated water is prepared.

COMPONENT REPLACEMENT

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 components are wired in the
same manner as old components. An examination of the circuit schematic shows
that the safety components 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.

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 controller, 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 relay switch
opens. This stops the signal to the gas control valve and shuts off gas to the
main burner. The pilot flame remains lit. When the kettle cools below the set
temperature, the relay 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 43 PSI and to shut down the
burners until jacket pressure is decreased.

3. Pop safety valve, which will release steam if jacket pressure exceeds 50 PSI.

4. Tilt switch, which shuts off all burners when the kettle is tilted.

5. Gas pressure regulator built into the gas control valve.

REPLACEMENT PARTS
