Installation, Operation and Care of
MODEL ES, EL & ET STEAM JACKETED KETTLES
KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE
GENERAL
Your Vulcan steam jacketed kettle is produced with quality workmanship and material. Proper
installation, usage and maintenance will result in many years of satisfactory performance.
Vulcan-Hart Company suggests that you thoroughly read this entire manual and carefully follow all of
the instructions provided.
INSTALLATION
Prior to installation verify that the electrical service agrees with the specifications on the machine data
plate located inside the front cover at the lower left.
UNPACKING
This kettle was inspected before leaving the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check
for possible shipping damage. If the kettle is found to be damaged, save the packaging material and
contact the carrier within 15 days of delivery.
LOCATION
Position the kettle in its final location. Check that there are sufficient clearances for operating and
servicing the kettle, and for proper clearance of the cover when raised. The kettle draw off faucet should
be located near a floor drain.
LEVELING
Place a spirit level on the rim of the kettle with the cover open. Adjust the feet to level the kettle leftto-right and front-to-back.
INSTALLATION CODES AND STANDARDS

OPERATION
WARNING: THE KETTLE AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING
AND SERVICING THE KETTLE.
BEFORE FIRST USE
Using a non-corrosive, grease-dissolving commercial cleaner, clean the protective metal oils from all
surface parts and interior of the kettle. Follow the cleaner manufacturer's directions. Rinse thoroughly
with warm water to remove all traces of the cleaner. Drain the kettle. Wipe dry with a soft clean cloth.
CONTROLS
On-Off Switch
— Turns power to the kettle on or off.
Thermostat Switch,
Low Water Cutoff Switch,
Limit Switch
— These three switches are wired in series and control the supply of
energy to the heating elements. Opening any one of these pressure
switches will shut off the power supply to the heating elements.
Thermostat
— Senses the temperature in the steam jacket. At a dial setting of 5 to
6, it will cut power off as the pressure gauge needle moves off zero.
The higher dial settings are for cooking, the lower ones for
holding. At the higher dial settings, the steam pressure in the
jacket will drop to 2 to 21/2 psi after the thermostat cuts the power
off and before it cuts it on.
Low Water Cutoff Switch
— Cuts off power to the heating elements if the jacket distilled water
level is too low.
Pressure Relief Valve,
Pressure Limit Switch
— Protect the kettle against excessive pressure should the thermostat
malfunction. The pressure relief valve is rated so that it will
relieve generated steam faster than the heating elements can
generate it.
Pressure Gauge
— Indicates pressure in the jacket.
Sight Glass Assembly
— Visually shows the distilled water depth in the steam jacket.
Thermostatic Air Vent
— Lets air out of jacket as steam is generated; closes at
approximately 180°F to prevent the steam from escaping.
Fill Assembly
— Location for adding distilled water to the jacket. It is equipped with
a manual valve plus a check valve to prevent a discharge should the
manual valve be inadvertently opened while the jacket is under
pressure.
Food Draw-Off Valve
— Allows food and liquid to be drawn off from the kettle.
–5–
FILLING THE WATER JACKET
APPLIANCE FAILURE CAUSED BY INADEQUATE WATER QUALITY IS NOT COVERED UNDER
WARRANTY.
Fill the outer jacket of the kettle to the top of the band on the gauge glass with a chemically pure distilled
water, along with a suitable rust inhibitor.
It should not be necessary to frequently add distilled water to the jacket, as little distilled water is lost
in normal operation.
USING THE KETTLE
Before use, preheat the kettle empty. Set the thermostat at No. 12 or No. 13. When the orange light
goes out, load food and set thermostat dial for desired cooking temperature.
KETTLE FOOD DRAW-OFF VALVE
When the food draw-off valve is turned off (no liquid or food product flow), the valve handle will point
to either the 9 o'clock or 3 o'clock position. To open (allowing liquid or food product flow), slowly pull
handle forward. With the valve handle pointing to the 6 o'clock position, the valve is in a fully open
position. This food draw-off valve system requires a right or left turn to close off food flow.
To allow for evenly mixed food products to flow into a food service pan or stock pot, first thoroughly stir
the food product in the kettle before opening the food draw-off valve. Pans or pots may be placed on
a portable dolly for easy movement and handling.
CLEANING
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING.
After Each Use
Clean and flush the kettle immediately after each use, especially if the product cooked contained salt
or vinegar in any concentration.
Daily — Kettle Food Draw-Off Valve
1. With kettle empty, pull valve handle to the 7 o'clock position. (A pin locks the valve plug into the
valve body and you can only remove or replace the valve plug when the valve handle is in the
7 o'clock position.) Kettles built before July 2003 thru March 1992 - the removable position is at 4
o'clock. Kettles built prior to March 1992 - the removable position is at 6 o'clock.
2. Pull tapered plug from valve body.
3. Using warm soapy water, wash the entire valve body and open area into the kettle interior.
4. Wash the interior and exterior of the valve plug. CAUTION: Do not drop or hit the valve plug.
This will nick or dent the soft metal.
–6–
5. After washing, lubricate the valve body and valve plug with Petro-Gel lubricant. Make sure all
interior mating surfaces are covered with this lubrication. This lubrication must be done every day
after use. If the food draw-off valve plug and inside of valve body are not lubricated, undesirable
leakage can occur, or the valve plug could stick in a partially open position when the kettle is up
to cooking temperature and the operator attempts to open the draw-off valve.
A 4-ounce tube of Petro-Gel is furnished with your kettle. You can reorder through your local service
agency or food service equipment dealer.
6. Each draw-off valve body and removable tapered draw-off plug is stamped with a set of corresponding
numbers. After cleaning and lubricating, make sure the body and plug numbers match before
reinserting the tapered plug.
7. Examine the valve plug and valve body for nicks and deep scratches. Do not attempt to push or
force the valve plug into the valve body if there are any obstructions, nicks, or deep scratches in
either the plug or body. Contact your local Vulcan authorized servicer.
8. Carefully slide the valve plug into the valve body. CAUTION: Do not attempt to slide valve plug
into valve body when valve handle is at any other than the 7 o'clock position. This will damage
the pin and the plug will not seat properly, causing leakage between the valve body and plug.
Kettles built before July 2003 thru March 1992 - the removable position is at 4 o'clock. Kettles built
prior to March 1992 - the removable position is at 6 o'clock.
Sight Glass Assembly
This component indicates the distilled water level inside the jacket and should be checked at least once
a day. The correct distilled water level is a point one-half the height of the glass. Extreme murkiness
indicates that the kettle jacket should be cleaned.
–7–
MAINTENANCE
WARNING: THE KETTLE AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING
AND SERVICING THE KETTLE.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE
DISCONNECT SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.
PERIODIC MAINTENANCE
1. Pressure Relief Valve
This protection device should be opened at least once a day to avoid lime build-up. Replace if
leakage occurs or it opens below rated p.s.i.
2. Low Water Cut-Off
This device should be removed and inspected for lime build-up at least once a year. The float must
move freely in its cage. Clean if necessary. Replace if lime or sludge cannot be removed to allow
the float to move freely.
3. Sight Glass Assembly
This unit indicates the distilled water level inside the jacket and should be checked at least once
a day. The correct distilled water level is a point one-half the height of the glass. Extreme murkiness
indicates the kettle jacket should be cleaned.
4. Draw-Off Valve
The faces of this valve should be lubricated with Petro-Gel daily to prevent sticking.
5. Vent
Annually, when cool, check the air vent and clear any obstructions.
6. Kettle Jacket Fluid
Draining the water from the jacket (or flushing the jacket) is not required or desirable at frequent
intervals and should be done only when there is evidence of scale or sludge inside the jacket.
To drain the jacket, remove the drain plug on the exterior bottom plate of the kettle.
The jackets are constructed of type 304 stainless steel, but they can pit and corrode under adverse
conditions. Prompt, careful cleaning will help prevent this. To clean and flush the jacket, remove
the low water cutoff switch and insert a water hose through this opening. When the jacket is refilled,
always use chemically pure water, along with two ounces of a boiler feed water treatment
compound. A 6-ounce bottle of treatment compound is available from Vulcan-Hart.

SERVICE
WARNING: THE KETTLE AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING
AND SERVICING THE KETTLE.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE
DISCONNECT SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.
GENERAL NOTES
The signal light marked "Power On" glows when the On-Off switch is turned to ON, and electric power
is supplied to the kettle.
The signal light marked "Heat On" glows when the thermostat switch is closed (thermostat calling for
heat).
The thermostat, with the dial at the highest setting, should cut the power off at a jacket pressure of
12 to 13 p.s.i. and before the pressure relief valve opens.
The pressure limit switch is set to open when the jacket pressure reaches 15 p.s.i. and to close when
jacket pressure drops to 6 p.s.i.
The On-Off switch is a two-pole switch and opens both lines of the control circuit. The thermostat
switch, the low water cut-off switch and the pressure limit switch are single-pole switches.
SERVICING PROCEDURES
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE
DISCONNECT SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.
Thermostat
To recalibrate, remove the dial by pulling it forward, and slightly turn the small screw in the center of
the hollow dial shaft. Recalibration is indicated if the thermostat, with the dial at the highest setting,
fails to shut the power off before the pressure relief valve opens, or if it shuts the heating elements off
before the jacket pressure reaches 13 p.s.i.
To replace the thermostat, remove two screws under the dial, disconnect the wire leads, unscrew the
packing gland around the capillary tube where it enters the jacket, unscrew the bushing the gland was
threaded into, and pull the bulb from the jacket.
When installing the new thermostat, insert the bulb first. Be careful that the capillary tube is not bent
sharply, that the packing gland seal is pressure tight, that the wire leads are clean and terminal screws
are tight, and that the capillary tube is positioned so there is good clearance (3/4" minimum) between
it and any uninsulated electrically live part.
–9–
Low Water Cut-Off
This service is indicated if the distilled water in the steam jacket is at the proper level but the switch does
not close to make the circuit across the two top terminal screws (the bottom two are not used), if leakage
is observed from the switch case, or if the distilled water level is near the bottom of the gauge glass
and the switch does not open.
To replace or to check the switch, remove the lead wires, remove the two screws and the metal cover
over the switch. Remove the four flat head screws holding the switch in place, then remove the switch.
To check the switch, gently press the bottom of the rocker toward the switch body; this should close
the switch. Then press the rocker in the other direction; this should open the switch. When installing
the switch, be sure the word "TOP" on the switch is at the top.
To replace the complete unit, remove the lead wires, remove the ten screws around the base of the
metal switch cover and pull the complete unit forward. When installing the new unit, be sure the word
"TOP" on the switch is at the top and that the side of the square terminal block is vertical.
Pressure Limit Switch
This service is indicated if a circuit check shows the switch is not closed or if the switch is opening at
too low a pressure. It was factory set to open at 15 p.s.i. and to close at 6 p.s.i.
To remove the switch for service, disconnect the tubing from the bottom of the unit and remove two
screws with nuts which anchor the mounting bracket for the unit.
The cut-out and cut-in pressure setting of the switch is shown on the dial and is adjustable with slotted
square shanks at the top of the case. Adjust the cut-out pressure setting first. If this adjustment does
not cure the trouble, replace the complete unit.
Magnetic Contactor
This service is indicated if a circuit check shows power at the proper voltage is supplied to the magnet
coil terminals, yet the contactor fails to open or close as it should or it chatters or hums.
A chatter or a humming noise usually is the result of dirt or lint on the armature pole faces or around
the armature core so that the magnet coil does not completely pull the armature into the sealed position.
This can usually be corrected by blowing or wiping the pole faces clean. The pole faces are at the
bottom of the contactor directly behind the magnet coil terminals.
To inspect the contactor contact points, on 70 and 125 ampere contactors, remove the grey color
plastic arc shield at the top of the contactor by removing the two screws holding it in place. The 50
ampere contactor has no arc shield. For a better view or for other service, remove the two wires to the
magnet coil at the coil terminals (terminals at the bottom of the contactor), remove the two screws
holding the coil in place and lift the coil and armature assembly out.
Pitted contacts should be replaced. These may be obtained from Vulcan-Hart.
Electric Heating Elements
This service is indicated if a check with an ammeter shows the K.W. input is not proper. Proper
amperage for each K.W. input is shown under ELECTRICAL CONNECTIONS in this manual.
– 10 –
To replace an element, drain the kettle jacket. Remove the wire from the element terminals, remove
the four bolts in the element flange and pull element out. When replacing the element, always use a
new gasket.
Replace On-Off Switch
Remove the large nut on the outside of the control box holding the unit to the box. The switch has two
separate contact blocks held by special slotted screws to the back of the switch. It may be necessary
to replace only one block. When remounting on the box, be sure the gasket is properly positioned
between the switch and inner surface of the control box and the small pin at the top front of the switch
fits into the small hole above the large hole in the control box wall.
Replace Signal Light
Remove the screw between the two signal lights in front of the control box. Note the position of the bar,
the signal lights and the gaskets and replace with parts in the same position, with the bar against the
back surface of the metal ring on the light, and the gasket around the light and between the metal ring
and the inner surface of the control box wall.
Replace Pressure Gauge
Disconnect the copper tubing from the back of the gauge, remove two nuts holding the "U" strap in
place, remove the "U" strap and remove gauge.
Correct Leaking Draw-Off Valve
Remove the plug from the body of the valve. Examine the tapered surface of each. Carefully dress
any raised places with a very fine file or with emery cloth. Do not cut below the surface when removing
any raised places. Coat the plug lightly with lapping compound, insert the plug in the body and rotate
to seat the plug in the body. Use a medium grade of compound first and finish with a fine grade lapping
compound. Valve grinding compound from an automobile supply house is suitable for this.
Clean surface thoroughly after use of lapping compound. Lubricate surfaces lightly with Petro-Gel to
prevent the plug from sticking.
