OM-KPT/KLT-DS 3
Equipment Description
The Blodgett KLT/KPT 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 as optional equipment.
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.
The kettles in this series employ a worm and gear tilting mechanism, which is
completely enclosed.
The kettles are mounted in two ways. The KPT Model 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. The KLT Model is supported by a tubular, stainless steel tri-leg frame
with adjustable floor flanges.
Options include:
1. Lift-off cover (for kettles smaller than 60 gallons)
2. Cover with counter-balancing actuator (for 40 gallon and larger kettles)
3. Fill faucets with swing spout
4. Basket cooking system
5. Kettle brush kit
6. 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.
For proper sanitation, a continuous seal
is required between pedestals or flanges
and the mounting surface.
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.
7. Any mechanical change must be approved by the Food Service Engineering
Department.
Floor-Mounted Models
1. Install the unit on a level surface. Ensure that there is adequate clearance at the
sides and rear, as required by the specification drawings. Anchor the pedestal or
legs securely to the floor.
2. Apply a continuous bead of clear silicone sealant (No. 732 or equivalent) to the
junction between the pedestal or leg flange and the surface, as shown in the

Initial Start-Up
IMPORTANT
BE SURE ALL OPERATORS READ,
UNDERSTAND AND FOLLOW THE OPERATING
INSTRUCTIONS, CAUTIONS, AND SAFETY
INSTRUCTIONS CONTAINED IN THIS MANUAL.
WARNING
AVOID EXPOSURE TO ESCAPING STEAM,
WHICH CAN CAUSE SEVERE BURNS.
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.
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 pulling out on its chain, (or lifting its lever on older
models) 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 draw-off 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 Certified Service Agency.

Operation
WARNING
AVOID EXPOSURE TO ESCAPING STEAM,
WHICH CAN CAUSE SEVERE BURNS.
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
PRODUCT AND SAFE TRANSFER.
WARNING
WHEN TILTING KETTLE FOR PRODUCT
FOR PRODUCT TRANSFER:
1) WEAR PROTECTIVE OVEN MITT AND
PROTECTIVE APRON.
2) USE CONTAINER DEEP ENOUGH TO
CONTAIN AND MINIMIZE PRODUCT
SPLASHING.
3) PLACE CONTAINER ON STABLE, FLAT
SURFACE, AS CLOSE TO KETTLE AS
POSSIBLE.
4) STAND TO LEFT OR RIGHT SIDE OF
KETTLE WHILE POURING – NOT
DIRECTLY IN POUR PATH OF HOT
CONTENTS.
5) POUR SLOWLY, MAINTAIN CONTROL
OF KETTLE AT ALL TIMES, AND
RETURN KETTLE BODY TO UPRIGHT
POSITION AFTER CONTAINER IS
FILLED OR TRANSFER IS COMPLETE.
6) DO NOT OVERFILL CONTAINER. AVOID
DIRECT SKIN CONTACT WITH HOT
CONTAINER AND ITS CONTENTS.
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.
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 a
Certified Service Agency, or refer to the Troubleshooting section of this manual.
OM-KPT/KLT-DS 9
Sequence of Operation
The following “action-reaction” outline is provided to help you understand how the
equipment functions.
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 which serves the kettle. In the jacket
steam releases its heat to the kettle as it condenses into water. The steam trap allows
condensate (water) to leave the kettle while holding the steam in.
When the steam supply is shut off, condensation of the remaining steam produces a
vacuum in the jacket, but the check valve in the condensate return line keeps water from
flowing back into the jacket.

Maintenance
WARNING
WHEN TESTING, AVOID ANY EXPOSURE
TO THE STEAM BLOWING OUT OF THE
SAFETY VALVE. DIRECT CONTACT
COULD RESULT IN SEVERE BURNS.
CAUTION
USE OF ANY REPLACEMENT PARTS
OTHER THAN THOSE SUPPLIED BY THE
MANUFACTURER OR AN AUTHORIZED
SUPPLIER WILL VOID ALL WARRANTIES AND
COULD INJURE THE OPERATOR OR DAMAGE
THE EQUIPMENT.
NOTICE: Contact an authorized representative when repairs are required.
Periodic Maintenance
A Service Log is provided at the back of this manual with the warranty information.
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:
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 service representative.
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.
NOTE: Service performed by other than factory authorized 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.

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.
CAUTION
DO NOT MIX DIFFERENT KETTLE DRAWOFF
ASSEMBLY PARTS WHEN WASHING.
THEY ARE NOT INTERCHANGEABLE
NOTICE
NEVER LEAVE A CHLORINE SANITIZER IN
CONTACT WITH STAINLESS STEEL
SURFACES LONGER THAN 30 MINUTES.
LONGER CONTACT CAN CAUSE STAINING
AND CORROSION.
A. Suggested Tools
1. Cleaner, such as Klenzade HC-10 or HC-32 from ECOLAB, Inc
2. Long- and short-handled kettle brushes in good condition
3. Brush suitable for cleaning the draw-off port
4. Sanitizer such as Klenzade XY-12
5. Film remover such as Klenzade LC-30
B. Procedure
1. Clean food-contact surfaces as soon as possible after use, preferably
while the kettle is still hot. 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 with lukewarm water. After flushing the
kettle, close the draw-off valve.
3. Prepare a hot solution of the detergent/ cleaning compound as instructed
by the supplier. Set some of this solution aside to use in cleaning the
draw-off valve and pipe.
4. Clean the unit thoroughly, inside and outside.
5. Drain the kettle.
6. Disassemble the tangent draw-off valve. Clean the draw-off pipe and each
valve part with a brush.
Scrapers or steel wool can harm
the kettle surface.
Use only a sponge, cloth or
plastic brush to clean the kettle.
7. Rinse the kettle and draw-off parts thoroughly with warm water, then
drain completely.
8. As part of the daily cleaning, clean all external and internal surfaces that
may have been soiled. Remember to check such areas as the underside of
the cover.
9. To remove burned-on materials, 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.
10. Do not use steel wool, which may leave particles in the surface and cause
eventual corrosion and pitting.
11. The outside of the unit may be polished with a stainless steel cleaner such
as “Zepper” from Zep Manufacturing Co.
12 OM-KPT/KLT-DS
Cleaning
12. When equipment needs to be sanitized, use a solution equivalent to one
that supplies 200 parts per million available chlorine. Obtain advice on
sanitizing agents from your supplier of sanitizing products. Following the
supplier’s instructions, apply the agent after the unit has been cleaned and
drained. Drain and thoroughly rinse off the sanitizer.
13. It is recommended that each piece of equipment be sanitized just before
use.
14. If there is difficulty removing mineral deposits or a film left by hard water
or food residues, clean the kettle thoroughly and use a deliming agent, in
accordance with the manufacturer’s directions. Rinse and drain the unit
thoroughly before further use.
15. If cleaning problems persist, contact your cleaning product representative
for assistance. The supplier has a trained technical staff with laboratory
facilities to serve you.
16. If your unit is equipped with a tangent draw-off valve, disassemble it and
clean the draw-off port and each valve part with a brush.
