1.1 DESCRIPTION
The Market Forge direct connected steam
jacketed kettle is a steam operated pressure ves sel designed for cooking. It consists of a stain
less steel kettle with double-wall construction,
forming a surrounding chamber around the
lower 2/3 of the kettle into which steam is introduced as a source of heat for cooking. Steam input plumbing is equipped with a manual control
valve. Units are supplied mounted on legs or a
pedestal base, in tilting and stationary models,
and in capacities ranging from 5 to 150 gallons
(19 to 565 liters). Safety valves are standard on
all units except table-top models, on which a
safety valve is optional.
1.1.1. Table-Top Kettles
Table-top kettles are available in 5 to 10 gal
lon (19 and 38 liter) capacities, and are mounted
in trunnion assemblies which must be mounted
to a cabinet top. The trunnion pivots contain
steam input and return connections. Tilting is
accomplished manually by pulling a handle af
fixed to the kettle rim to rotate the kettle in its
trunnion mounts.

SECTION 4 MAINTENANCE
4-1 S-2209
4.1 GENERAL
This section contains both preventive and
corrective maintenance information. Preventive
maintenance may be performed by maintenance
personnel at the establishment in which the ket -
tle is installed. It is recommended that user per
sonnel never attempt to make repairs or replace
ment to the equipment without the assistance of
authorized service. Assistance in service methods or a current directory of Authorized Service
Agencies may be obtained by contacting Market
Forge. See Subsection 1.2.
4.2 PREVENTIVE MAINTENANCE
The most important preventive maintenance
operation on the steam jacketed kettle is the
cleaning procedure after each use detailed in
Section 2. Additional preventive maintenance
operations are presented in this section.
4.2.1 Tilting Mechanism Lubrication
Lubrication of the hand wheel tilting mechanism on kettles so equipped is the only required
preventive maintenance other than daily cleaning. Inspect the worm screw, tilting gears and
bearings occasionally (at least once a year). Lubricate as required, using a graphite lubricant
(part #10-3512) or equivalent.
4.3 REPAIR AND REPLACEMENT
In the event that the kettle fails to operate
correctly, the difficulty should first be isolated to
either the kettle itself or its steam supply. While
mechanical problems are obvious faults of the
kettle, any deficiency in volume or pressure of
steam should be traced to the steam generator
and the cause det ermined. Steam input requirements are listed in Appendix A, Steam Input
Requirements of Direct Connected Kettles.
4.3.1 Draw-off Valve Repairs
4.3.1.1 Common Leak Repairs
To repair a valve leak, the source must first
be determined. Leaks from around the valve
stem are corrected by replacing the "0" ring.
Dripping from the valve outlet which occurs with
the valve tightly closed indicates faulty seating
of the valve disc against the valve seat. Dripping
of this kind is often corrected by cleaning residue
from disc and seat using very fine emery.
4.3.1 2 Valve Seat Lapping
Should either the disc or seat be found to be
damaged, it is necessary to either replace the
entire valve, or perform the lapping procedure as
follows:
1. Disassemble the valve and clean both the
disc and the valve seat.
2. Attach the handle to the stem with the valve
bonnet removed.
3. Apply a good grade of fine lapping compound
to the disc and insert it into the valve to make
light contact against the seat.
4. Rotate the stem disc against the seat by turn ing the handle, allowing the stem to wobble
in the space normally occupied by the bon
net. Continue with light pressure until com
pound dries.
5. Reassemble and test for leaks with valve
closed. If dripping occurs, repeat the lapping
procedure as many times as required to ob tain a watertight seal.
