Equipment Description

A. All Models

The Groen D Series are deep type, tilting kettles
with direct steam-heated 2/3 jackets. The
stainless steel kettles have welded, reinforced
rims and butterfly shaped pouring lips. The liner
and pouring lip of all kettles are 316 stainless
steel. They are ASME shop-inspected, and are
registered with the National Board. The kettles
have a 180 emery grit interior finish and a bright
semi-deluxe exterior finish.

Every unit requires a remote steam source. The
steam supply is controlled by an inlet valve, and
enters the jacket through one trunnion directly
into the jacket. Steam pressure forces
condensate out a dip tube through the other
trunnion. Both steam and condensate lines are
concealed within the support structures of the
various models. The tale at bottom right shows
the standard kettle sizes for each model.

These kettles operate safely and efficiently at
various steam pressures above five PSI, with
upper pressure limits assured by the provided
safety valve. Operation also requires a globe
valve on the steam inlet and a strainer, steam
trap, and check valve on the condensate outlet.
These may be ordered from Groen as optional
equipment.

D Series kettles are emptied by tilting, but
optional tangent draw-offs are available. The
standard draw-off is two inch outer diameter
stainless steel, with compression disc valve and
a removable stainless steel strainer that has 1/4
inch perforations. Strainers with 1/8 inch or no
perforations are also available. The table on the
bottom right shows the sizes of draw-offs which
can be furnished with each model. When
equipped with a tangent draw-off the designation
“T” is added to the model designation.

The kettles in this series employ a worm and
gear tilting mechanism, which is completely
enclosed.

D Series kettles are mounted in three ways.
Model D is suspended in a stainless steel yoke
on a pedestal base. The outer circumference of
the base is flanged down for proper sealing to
the floor. Model DL is supported by a tubular,
stainless steel tri-leg frame with adjustable floor
flanges. The wall-mounted model MW/D has a
supporting frame enclosed in a stainless steel,
drip-proof housing. The frame must hang on an
in-wall carrier which may be purchased as an
option.

Other options include:

1. No. 31 lift-off cover (for kettles smaller than
60 gallons)

2. No. 51 cover with counter-balancing actuator
(for 40 gallon and larger kettles)

3. Fill faucets with swing spout

4. Gallon Master water meter

5. TRI-BC basket cooking system

6. Kettle brush kit

7. Operating pressures up to 90 PSIG

Installation

WARNING

THIS UNIT MUST BE INSTALLED BY PERSONNEL QUALIFIED TO WORK WITH PLUMBING.
IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO
EQUIPMENT.

A. All Models

1. Installation under a ventilation hood is
recommended. Consult local codes.

2. Install and anchor the kettle on a level
surface.

3. If the steam supply pressure is greater than
the maximum working pressure stamped on
the nameplate, you must install a pressure
reducing valve in the steam supply line near
the kettle.

4. Connect the steam supply line to the steam
inlet fitting. Include a steam control valve
and an appropriate safety valve. To obtain
the full heating capability of the kettle, the
steam supply line must be as large as the
steam inlet fitting.

5. The safety valve is preset to relieve jacket
pressure that exceeds its rated limit. Do not
try to adjust the valve setting, and do not

allow the valve outlet or lever to be blocked.

6. Connect the kettle condensate return line to
the boiler return line, or to a drain. A
suitable steam trap, strainer, and check
valve must be installed. (See piping
diagram, Page 18).

7. Any mechanical change must be approved
by the Groen Food Service Engineering
Department.

B. Floor Mounted Models

wall. Fill all cracks and crevices, and wipe
away the excess.

Initial Start-Up

IMPORTANT

BE SURE ALL OPERATORS READ, UNDERSTAND
AND FOLLOW THE OPERATING INSTRUCTIONS,
CAUTIONS, AND SAFETY INSTRUCTIONS
CONTAINED IN THIS MANUAL.

Now that the kettle has been installed, you
should test it to ensure that it is operating
correctly.

1. Remove all literature and packing
materials from inside and outside of the
unit. Clean out any material that might
clog the tangent draw-off valve, if present.

2. Pour a small amount of water into the
kettle.

3. Open the steam inlet valve.

4. When the water begins to boil, inspect all
of the fittings to ensure that there are no
leaks.

5. Check the safety valve by lifting its lever
far enough to let steam escape. Then let it
snap back into place to reseat the valve so
that it will not leak.

6. Shut down the unit by closing the steam
inlet valve.

7. Operate the tilting mechanism and draw­off valve to confirm that they function
through the whole range of normal
operation.

If the unit functions as described above, it is
ready for use. If the unit does not function as
intended, contact your local Groen Certified
Service Agency.

WARNING

AVOID ANY EXPOSURE TO ESCAPING STEAM, WHICH
CAN CAUSE SEVERE BURNS.

OM-D

OM-D

Operation

Before operating a cold kettle, open the petcock
at the bottom of the jacket to drain any water left
by condensing steam. Close the petcock before
you open the steam inlet valve. Draining this water
decreases the “hammering” you hear when steam
enters a cold jacket.

To heat the kettle, open the steam inlet valve.
Adjusting the inlet valve allows the operator to
control the heating rate. Opening the valve more
allows steam to flow into the jacket faster, and
thereby heats the product faster.

The kettle operates efficiently with steam
pressures from five PSI to the maximum working
pressure for which the kettle was designed. The
maximum allowable pressure is stamped on the
kettle nameplate. It is 25 PSI for standard units.

WARNING

AVOID EXPOSURE TO ESCAPING STEAM,
WHICH CAN CAUSE SEVERE BURNS.

Once a day, while there is still steam pressure in
the jacket, bleed off any entrapped air and double
check the operation of the safety valve. Pull out
on its chain, or lift the lever far enough to let steam
escape. Then let it snap back into place to reseat
the valve so that it will not leak.

Tilting the Kettle

To transfer product or empty the kettle: turn the
handwheel counterclockwise. The kettle will hold
its position when you stop turning the wheel.

If the tilting mechanism seems to be locked, do
not use force to free the kettle. Call for assistance
from your Groen Certified Service Agency, or refer
to the Troubleshooting section of this manual.

WARNING

AVOID ALL DIRECT CONTACT WITH HOT
FOOD OR WATER IN THE KETTLE. DIRECT
CONTACT COULD RESULT IN SEVERE
BURNS.

TAKE SPECIAL CARE TO AVOID CONTACT
WITH HOT KETTLE BODY OR HOT
PRODUCT, WHEN ADDING INGREDIENTS,
STIRRING OR TRANSFERRING PRODUCT
TO ANOTHER CONTAINER.

CAUTION

DO NOT OVERFILL THE KETTLE WHEN
COOKING, HOLDING OR CLEANING. KEEP
LIQUIDS AT LEAST 2-3” (5-8 cm) BELOW
THE KETTLE BODY RIM TO ALLOW
CLEARANCE FOR STIRRING, BOILING

Maintenance

NOTICE: Contact Groen or an authorized Groen representative when repairs are required.

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. File the log
with the warranty.

Periodic inspection will minimize equipment down
time and increase the efficiency of operation. The
following points should be checked:.

1. Once a day, with pressure in the jacket,
check the operation of the safety valve. Lift
the lever of the safety valve until steam is
released. Then release the lever and let the
valve snap shut. If the lever does not
activate, or there is no evidence of
discharge, or the valve leaks, immediately
discontinue use of the kettle and contact a
qualified Groen service representative.

WARNING

WHEN TESTING, AVOID ANY EXPOSURE TO
THE STEAM BLOWING OUT OF THE
SAFETY VALVE. DIRECT CONTACT COULD
RESULT IN SEVERE BURNS.

2. At least once every 90 days, inspect fittings
and valves for signs of damage or wear.
Regularly examine trunnion packings and
valve seats for wear, and replace them when
necessary.

CAUTION

USE OF ANY REPLACEMENT PARTS
OTHER THAN THOSE SUPPLIED BY GROEN
OR AN AUTHORIZED SUPPLIER WILL VOID
ALL WARRANTIES AND COULD INJURE
THE OPERATOR OR DAMAGE THE
EQUIPMENT.

NOTE: Service performed by other than factory­authorized personnel will void all warranties.

3. Lubricate trunnions and gears with a good
grade of high temperature grease. Grease
trunnions at least once every 60 days, and
grease gears when inspection shows that they
are dry.

4. If the kettle cover has an actuator, lubricate it
every 90 days.

NOTE: Use only Calcium Complex Nr. 2 Grease,
which is available from Groen (Part No. 093703).

Sequence of Operation

The following “action-reaction” outline is provided
to help the user understand the function of the
equipment.

When the steam inlet valve is opened, steam
flows into the jacket at a pressure determined by
the boiler system or by the pressure reducing
valve that serves the kettle.

In the jacket, steam transfers heat to the kettle
as it condenses into water. The steam trap
allows condensate (water) to leave the jacket,
while it holds steam in. When the steam is shut
off, condensation produces a vacuum in the
jacket, but the check valve in the condensate
return line keeps water from flowing back into
the jacket.
