Introduction
DESCRIPTION
All direct connected steam jacketed kettles pertaining to
this manual are direct steam operated pressure vessels
of a double-wall stainless steel construction forming a
steam chamber (jacket) enveloping the lower two thirds
of the kettle bowl surface. Kettles included are tilting
and stationary, oor mounted in xed positions either on
legs with adjustable anged feet or pedestals. All kettles
are equipped with a drain cock, safety relief valve and a
steam control valve.
FUNCTIONING MODE
Market Forge direct connected steam jacketed kettles
consist of a stainless steel bowl and a stainless steel
jacket which envelopes two thirds of the lower surface of
the bowl thus forming a sealed pressure vessel (chamber) into which steam is introduced by means of a manual
control valve.
The kettle bowl is the container for the food product which
ideally should be of a liquid or semi-liquid consistency to
achieve complete contact with the bowl surface and thus
fully absorb the heat transmitted through the surface.
The temperature required for the cooking process to function adequately must be greater than the boiling point of
the liquid food product. Further, the greater the steam
pressure used, the higher the temperature and conse-
quently the quicker the cooking process. For example,
steam pressurized at 30 PSI attains a temperature of
274°F (135°C).

Installation Instructions
1. Select a location to provide drainage for kettle pour
path when tilted and for draw-off valve if so equipped.
2. Mark hole locations through anged adjustable feet
on tri-leg models and through pedestal base on pedestal models. Remove kettle.
3. On hole locations marked, drill holes and insert expansion shields to accommodate 5/16” size lag bolts.
4. Reposition kettle. On tri-leg models level kettle by
making necessary adjustment on anged foot.
5. Bolt down kettle and seal with Silastic or other equivalent sealing compound. Sealant must be applied not
only to bolt heads but also around anges or pedestal
base making contact with oor surface to full NSF
requirements.
6. Connect steam line (3/4” pipe size) to the kettle, making sure there is a steam control valve strainer fairly
convenient to the kettle.
7. Connect kettle condensate return line to a drain or to
a boiler return line. Each kettle return line must have
a suitable steam trap. Boiler return lines must have
a check valve.
8. Safety relief valve on kettle must not be plugged as it
is set to relieve excess pressure in the kettle.
9. If incoming steam pressure is greater than kettle maximum operation pressure then a pressure reducing
valve must be installed in the line.
10. If large amounts of water accumulate in the steam
line it will be necessary to install one or more ball oat
traps in the line to eliminate the water.
11. A steam line pressure gauge is also recommended to
determine the actual amount of steam being supplied
to the kettle.
12. Check for proper operation.

OPERATION
Operating Instructions
TILTING KETTLES
1. If kettle has draw-off valve, close it.
2. Fill kettle with product to desired level.
3. Slowly turn the steam control valve ON to full open
position (counterclockwise).
4. The water or food should boil 2 to 3 gallons per minute. If it does not then incoming pressure and piping
should be checked to determine that it is adequate to
operate the kettle efciently.
5. Regulate steam control valve depending on type of
food being prepared.
6. When food is cooked, turn off steam, remove food
and clean kettle immediately to prevent residue from
drying on kettle bowl surface.
STATIONARY KETTLES
1. Ensure that draw-off valve is closed.
2. Fill kettle with product to desired level.
3. Slowly turn the steam control valve ON to full open
position (counter clockwise).
4. The water or food should boil 2 - 3 gallons per minute. If it does not then incoming pressure and piping
should be checked to determine that it is adequate to
operate the kettle efciently.
5. Regulate steam control valve depending on type of
food being prepared.
6. When food is cooked, turn off steam, remove food
and clean kettle immediately to prevent residue from
drying on kettle bowl surface.
CAUTION
The equipment and its parts are hot. Use care
when operating, cleaning and servicing.
OPERATION
8
CAUTION
Do not use cleaning agents that are corrosive.
Use of cleaning agents that contain chloride, acids or
salts are corrosive and may cause pitting and corrosion
when used over a period of time; this will reduce the life
of the appliance.
Should pitting or corrosion occur, this is not covered by
warranty.
Follow the recommended cleaning instructions. Use a
mild detergent, warm water and rinse thoroughly.
Cleaning
STATIONARY KETTLE CLEANING INSTRUCTIONS
Your kettle should be cleaned immediately after each use.
1. Ensure that steam supply is OFF.
2. Pre-rinse inside of kettle thoroughly and drain to remove any food particles.
3. Using a nylon brush, clean kettle with a mild detergent and warm water rinse. Never use steel wool or
scouring powder as it will scratch stainless steel.
4. Open the tangent draw-off valve to allow soap and
water solution to drain. Rinse with clean water.
TILTING KETTLE CLEANING INSTRUCTIONS
Your kettle should be cleaned immediately after each use.
1. Ensure that steam supply is OFF.
2. Pre-rinse inside of kettle thoroughly and drain to remove any food particles.
3. Using a nylon brush, clean kettle with a mild detergent and warm water rinse. Never use steel wool or
scouring powder as it will scratch stainless steel.
4. Tilt kettle fully or open the tangent draw-off valve if
one is provided to allow soap and water solution to
drain. Rinse with clean water.
5. On kettles equipped with a draw-off valve, turn the
large hex nut counterclockwise by hand until it is
completely disengaged from the thread. Grasp knob
to valve and slowly pull out valve stem and disc. Do
not allow disc to come in contact with hard surfaces
since damage to disc may occur and result in valve
leakage. Wash the valve stem, disc and handle. Insert nylon brush with detergent into interior of valve
body and tangent draw-off tube and brush vigorously.
Replace valve stem assembly and engage hex nut
fully by hand. Flush kettle with clean warm water.
Leave valve open when kettle is not in use.
