Equipment Description
The Groen DH is a floor-mounted, tilting, steam
jacketed kettle with a thermostatically controlled,
self-contained, gas-heated steam source and
appropriate controls, mounted on a sturdy base.
The Model DH is available in 20, 40 or 60 gallon
capacities.
The body of the DH Kettle is constructed of
stainless steel, welded into one solid piece. The
kettle is furnished with a reinforced rim and a
butterfly shaped pouring lip. It has a steam jacket
which is ASME shop inspected and registered
with the national board for working pressures up
to 50 PSI. Kettle finish is 180 emery grit on the
inside and bright high buff polish on the outside.
The kettle is tilted with a hand crank to pour out
its contents. Stainless steel panels enclose the
controls and the base. Four stainless steel
tubular legs support the unit. Bullet feet on
each of the legs can be adjusted to level the
kettle. Standard DHT units include a two inch
tangent draw-off valve.
The self-contained steam source is heated by
propane or natural gas. Ignition is electronic.
The kettle is charged at the factory with
chemically pure water which contains rust
inhibitors. The steam source provides kettle
temperatures of 150º to approximately 295ºF (65
to 150ºC). Unit controls include a thermostat,
pressure gauge, safety valve, pressure limit
control, low water cut-off, power switch and gas
regulator valve. The gas supply shuts off
automatically when the kettle is tilted.
The unit must be specified for use with natural or
propane gas. Service connections for gas and
electricity are required. Standard power supply is
115 Volt. Alternate voltages (208V or 240V) are
available.

Use of Common Accessories
1.
Lift-Off or Counterbalanced Cover
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.
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
When putting a lift-off cover on the kettle,
position it on top of kettle rim, with its flat edge
facing the pouring lip.
WARNING
AVOID ALL DIRECT CONTACT WITH HOT
SURFACES AND HOT FOOD OR WATER
IN THE KETTLE. DIRECT CONTACT
COULD RESULT IN SEVERE BURNS.
When removing a lift-off cover:
a. Firmly grasp the handle, and lift the rear
edge (farthest from operator) 1-2” (3-5 cm)
to allow steam and water vapor to escape.
Wait 2-3 seconds.
b. Tilt cover to 45-60° angle to allow any hot
condensate or product to roll off cover back
into kettle.
c. Remove cover, ensuring that remaining hot
condensate or product does not drip on
operator, floor or work surfaces.
d. Place cover on safe, flat, sanitary, out-of-the-
way surface, or return to kettle.
CAUTION
DO NOT TILT KETTLE WITH LIFT-OFF
COVER IN PLA
CE. COVER MAY SLIDE
OFF, CAUSING INJURY TO OPERATOR.
2. 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 liner must be used for
products smaller than the basket mesh size,
(approx. ¼” (6 mm). This includes rice and small
pasta shapes.
a. Allow for displacement of the three baskets
and product. This may mean only half filling
the kettle. Test baskets 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 AT LEAST 2-3” (5-8 cm)
BELOW THE KETTLE RIM TO ALLOW
CLEARANCE FOR STIRRING, BOILING
AND SAFE PRODUCT TRANSFER.
OM-DH

Page 11
OM-DH
WARNING
AVOID ALL DIRECT CONTACT WITH HOT
FOOD OR WATER IN THE KETTLE. DIRECT
CONTACT COULD RESU
LT IN SEVERE
BURNS.
b. Load baskets on a level, stable work
surface.
c. Lift loaded baskets with both hands. Get
help from another person if the basket is too
heavy for safe handling.
d. Slowly lower product into kettle and securely
hook basket to the “Y” frame.
e. When removing baskets with cooked
product, lift straight up, ensuring basket
bottoms clear the kettle rim and pouring lip.
Wear protective oven mitts and protective
apron.
f. Allow hot water to fully drain from product,
before moving basket away from the kettle.
Do not rest baskets on kettle rim or pouring
lip. If baskets are too heavy for individual to
lift and safely move, get help. Remove
product immediately from basket into
another container, being sure to avoid
contact with hot product and hot basket or...
g. Place baskets with food on a stable, flat
surface, inside a solid steamer or bake pan,
to catch any remaining hot water draining
from product.
Sequence of Operation
The following “action-reaction” outline is provided to
help understand how the DH 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
remains lit. 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
46 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.
OM-DH

OM-DH
The pressure gauge should show a vacuum of
20 to 30 inches of mercury (Hg) and the water
level should be between the markers when th
e
kettle is cold.
Maintenance
NOTICE: Contact Groen or an authorized Groen Service Agent when repairs are required.
1.
Periodic Maintenance
A Maintenance & Service Log is provided at the
back of this manual with the warranty
information. Each time maintenance is
performed on your Groen 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:
a. 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” on page 13.
b. Also check the jacket water level every day.
It should be between the markers on the
gauge glass. If the level is low, see “Jacket
Filling and Water Treatment” on page 13.
c. Test the safety 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.)
d. 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.
WARNING
WHEN TESTING, AVOID ANY EXPOS
URE TO
THE STEAM BLOWING OUT OF THE SAFETY
VA
LVE. DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
e. Keep the primary burner gas jet air inlets
free of dust and lint.
f. The pilot flame should be blue. It should
envelop about ½ inch (12 mm) of the flame
sensor tip.
g. The gear housing has fittings for lubrication
of moving parts. The gears do not run in oil,
so periodic lubrication with grease is
necessary.
h. Frequency of lubrication depends on
operating conditions, but it should be done at
least once every six months.
i. 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.
j. Place liberal amounts of grease on the gear
to cover the arc that is in contact with the
OM-DH

Test the safety valve at least twice monthly.
Liberally grease the wheel where it contacts the
worm gear.
Add grease through Zerk Fittings.
worm gear.
k. Keep electrical wiring and connections in
good condition.
l. Keep the inside of the control console clean
and dry.
m. Keep burner slots clean.
2.
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:
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, 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.
3.
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.
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 valve is closed, and
remove the square head pipe plug with
open-ended 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.
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 Procedure
a. Obtain water treatment compound and a pH
test kit from your Groen Service Agent.
WARNING
TO AVOID INJURY, READ AND FOLLOW ALL
PRECAUTIONS ON THE LABEL OF THE
WATER TREATMENT COMPOUND.
b. Fill a mixing container with the measured
amount of water required. (See table).
Distilled water is recommended.
Kettle Model
Approximate Jacket
Capacity
DH-20, DHT-20 2½ Gallons
DH/1-40, DHT/1-40 3½ Gallons
DH-60, DHT-60 4 Gallons
c. 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.
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.
f. As you add water to the jacket, check water
level to ensure that it is between minimum
and maximum marks on glass. Stop adding
water when it reaches the maximum marker
on the gauge.
g. 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.
5.
Component Replacement
WARNING
BE FO RE R EPL AC ING A NY P ART S,
DISCONNE
CT 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 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.

When attachin g the draw-off valve, just handtighten the nut.
Cleaning
1. Suggested Cleaning Supplies:
a. Cleaner, such as Klenzade HC-10 or HC-32
from ECOLAB, Inc.
b. Kettle brushes in good condition.
c. Sanitizer such as Klenzade XY-12.
d. Film remover such as Klenzade LC-30.
2. Precautions
Before cleaning, shut off the kettle by turning the
thermostat dial to “OFF,” and shut off all electric
power to the unit at a remote switch, such as the
circuit breaker.
WARNING
KEEP WATER AND SOLUTIONS AWAY FROM
CONTROLS
AND ELECTRICAL EQUIPMENT.
NEVER SPRAY THE SUPPORT
HOUSING OR
ELECTRICAL CONNECTIONS.
CAUTION
MOST CLEANERS ARE HARMFUL TO THE
SKIN, EYES, MUCOUS MEMBRANES, AND
CLOTHING. PRECAUTIONS SHOULD BE
TAKEN. WEAR RUBBER GLOVES, GOGGLES
OR FACE SHIELD, AND PROTECTIVE
CLOTHING. READ THE WARNINGS AND
FOLLOW THE DIRECTIONS ON THE LABEL
OF THE CLEANER CAREFULLY
3. Procedure
a. 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.
b. 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.)
c. 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.
d. Model DHT only: Disassemble the tangent
draw-off valve. Clean the draw-off port and
each valve part with a brush.
CAUTION
DO NOT MIX PARTS OF DIFFERENT
DRAWOFF VALVE ASSEMBLIES. THE PARTS ARE
NOT INTERCHANGEABLE.
e. Rinse the kettle and draw-off valve parts
thoroughly with hot water, then drain
completely.
f. When you reassemble the draw-off valve,
hand-tighten the nut which holds it in place.
g. As part of the daily cleaning program, clean
soiled external and internal surfaces.
Remember to check the sides of the unit and
control housing.
h. 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.
