INTRODUCTION

This manual contains general, maintenance, parts and service information for Market Forge Modular Direct
Connected Tilting Steam Jacketed Kettles. A parts list is included in which each replaceable part is identied
and shown in an accompanying illustration unless otherwise indicated.

DESCRIPTION:

Market Forge MT6 and MT10 Tilting Steam Jacketed
Kettles are mounted on a modular stainless steel cabi­net. Double wall construction around the lower half
of the kettle forms a surrounding chamber inot which
steam is introduced as a source of heat for cooking.

Steam input plumbing is equipped with a manual con­trol valve. Condensate is removed through a steam trap
connecting with the kettle drain plumbing assembly. A
swing nozzle, hot-cold combination faucet provides a
source of water for addition to the kettle for cooking
and cleaning.

The 6 gallon kettle is mounted in a trunnion assembly
to the modular cabinet top. The trunnion pivots include
steam input and return connections for the kettle. Kettle
tilting is accomplished manually by moving the handle
xed to the rim so as to rotate the kettle in a trunnion.

SERVICE:

Modular kettles are exceptionally and durable cooking
equipment requiring a minimum of service other then
routine cleaning and preventive methods explained
on page 2. Should repairs be required, a network of
authorized service agencies is available to assist with
prompt service. A current directory of authorized ser­vice agencies may be obtained by contacting:

OPERATING

Consult boiler information or instructions plate and
complete all start-up instructions.

OPERATE KETTLE AS FOLLOWS:

Check pressure gauge of steam supply to ensure

1.

steam input is at approximately 15 PSI (1.0kg/cm2)
to a maximum of 50 PSI (3.5 kg/cm2). For direct
connected steam, turn on external steam supply

valve.

Load kettle with food to be cooked.

2.

Add water for cooking by turning swing nozzle over

3.

kettle and using combination faucet.
Turn steam valve to full counterclockwise position

4.

to allow steam to ow into jacket. Wait until food
reaches desired temperature.

Adjust subsequent cooking temperature by turning

5.

steam control valve. Turn clockwise to reduce heat

(steam ow) and counterclockwise to increase heat
(steam ow).

Close steam control valve and remove food from

6.

kettles as soon as cooking is complete to prevent
overcooking. (OLD Style - Place food pan under kettle

being used and tip kettle forward using kettle handle.
NEW Style - Attach splash guard to food pan. Place
food under kettle being used and tip kettle forward using

kettle handle). (NOTE: Before tilting kettle, ensure that
a.) Swing nozzle is rotated clear of kettle. b.) Kettle is
not full. If kettle is full ladle out 2 gallons of contents by
hand.)

Complete Cleaning Procedure (see below).

MAINTENANCE

GENERAL:

This section contains both preventive and corrective
maintenance information. Preventive maintenance
may be performed by maintenance personnel at the
establishment in which the kettle is installed. It is rec­ommended that user personnel never attempt to make
repairs or replacements to the equipment without the
assistance of authorized services. Assistance in ser­vice methods or a current directory of authorized ser­vice agencies may be obtained from Market Forge (see

page 1 for contact information).

PREVENTIVE MAINTENANCE:

The most important preventive maintenance opera­tion on the steam jacketed kettle is the cleaning pro­cedure. Cleaning should be faithfully completed at the
end of each day, Including cabinet doors, counter-top,
xtures, kettle lid, etc, should be washed and rinsed to
remove all food spills.

CLEANING PROCEDURE AS FOLLOWS:

1.

Fill kettle with water and mild detergent immediate­ly after removing food from the kettle.

2.

Remove food soil using a nylon brush. (NOTE:

Never scrape the inside of the kettle with metal tools,
steel scouring pads or abrasive cleaners. Scratches will
result which ruin the general appearance of the kettle
and make it harder to clean and maintain in a sanitary

condition).

Loosen food which is stuck to the kettle by allow-

3.

ing it to soak. Also, a small amount of steam may
help.

4.

Place clean-Up pan under kettle being washed by
inserting clan-up pan drain extension into counter­top drain opening. (NEW Style - Attach splash guard

to clean-Up pan). Tilt kettle to pour out wash water.

Rinse kettle with hot water.

5.

Thoroughly wash and rinse kettle exterior and cabi-

6.

net exterior.
Thoroughly dry unit.

REPAIR AND REPLACEMENT

In the event that the kettle fails to operate correctly,
the difculty should rst be isolated to either the kettle
itself or the steam supply which heats the kettle. While
mechanical problems are obvious faults of the kettle,
any deciencies in volume and pressure of the steam
should be traced to the steam generator and the cause
determined. Steam input requirements are listed be­low. This list recommends delivered boiler horsepower
for kettle size and steam ow.

MT6 1/3 BHP 15-30 PSI
MT10 1/2 BHP 15-30 PSI
MT6T6 1/3 BHP 15-30 PSI
MT10T6 1/2 BHP 15-30 PSI
MT10T10 1/2 BHP 15-30 PSI
LFT6 1 BHP 15-30 PSI
LFT10 1 BHP 15-30 PSI
LFT10T6 1 BHP 15-30 PSI
LFT10T10 1 BHP 15-30 PSI

CABINET EXTERIOR REMOVAL:

Side and rear panels of all cabinets in which kettles are
mounted are easily removed without the use of tools.
Each panel is grasped at the bottom edge and pulled
out sharply to release it from the panel mounting brack­ets shown in gure 6 on page 9. Replacement is com­pleted by pushing panel up under the cabinet top and
pressing in at the bottom until panel mounting brackets
are engaged.

Doors may be removed to improve access to cabinet
interior for repairs as shown in gure 6 on page 9 and

10. The two at head screws, nuts, and holding cabinet

hinge are removed to lift the door out shown in gure
6 on page 9 and 10. When doors are remounted, the
nal tightened position of hinge determines the align­ment of the door and must be set with care, also shown
in gure 6 on page 9 and 10.

TRUNNION MOUNTED KETTLE DISASSEMBLY:

Trunnion mounted kettles may be removed from the
cabinet top for replacement of worn o-rings and lubri­cation of trunnion parts.

Disassemble as follows:

Disconnect both steam inlet and condensate return

1.

plumbing connected to kettle legs from inside of
cabinet.
Remove 3/8” nuts and washer used to fasten kettle

2.

legs to cabinet top.
Lift kettle with legs attached off of cabinet top.

3.

Insert blade of screwdriver in slots of trunnion end

4.

6.
tle.
Remove o-rings and clean off trunnion parts includ-

7.

ing insides of support collars attached to legs.
