INSTALLATION & OPERATION MANUAL 10071-SB REV 0 (07/22)
Direct Steam Kettles Mounted on Electric Boiler Cabinet Base
General
Direct steam tilting kettle(s) mounted on a cabinet base, housing an ASME Code designed electric steam boiler approved
as a steam boiler restricted to operation at pressure not to exceed 15 psi. Hot and cold water ll faucet, 5” (152 mm) deep
sink with drain and splash guard(s). All models are suxed with either -6, -10 or -12 to indicate the capacity of the kettle(s)
in US gallons. The electric boiler may be rated at 24 kW, 36 kW, 42 kW or 48 kW. Operational on 208V, 220V, 240V, 380V,
415V or 480V and have optional CSD1 controls.
Functioning Mode
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 that surface.
The temperatures 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 consequently the
quicker the cooking process. For example, steam pressurized at 30 p.s.i. attains a temperature of 274 degrees Fahrenheit
(135 degrees Celsius).
In the initial stages of the cooking process when the steam comes in contact with the cold kettle bowl surface it condenses
and forms considerable amounts of water. A thermostatic steam trap has been plumbed to the exit end of the kettle jacket.
This trap is a mechanical device that closes on high temperatures and opens when the temperature drops thus allowing
the water formed from condensate to exhaust but retain steam under pressure.

OPERATION
For CSD-1 equipped boilers, see this section for Operation Instructions for CSD-1 Equipped Boilers.
Boiler Controls (Inside Cabinet)
Main Power Switch - ON lls the boiler tank and turns the boiler controls on. You should allow 20 minutes to ll
the tank and generate steam.
- OFF shuts o the boiler heaters and opens the Automatic Blowdown Valve, emptying
the boiler tank and releasing water and steam to the drain. This should be done daily to
remove sediment, lime, or scale.
Pilot Light - Indicates main power is ON.
Boiler Pressure Gauge - Should read 9 -11 psi during operation; 0 psi during shutdown.
Water Level Sight Glass - Observe level of water and water quality in the boiler. Murkiness in the water indicates
inadequate water quality; the owner must supply proper water to the boiler (see Service
Connections Water Quality Statement).
Water Level Control - While boiler is ON, briey open the water level control valve once a day to remove any sediment
that might accumulate. (see Periodic Maintenance Section).
Safety Valve - This valve will release (pop o) if the boiler has too much pressure. Once a week, this
valve should be tripped during operation to make sure it functions properly.
Operating Instructions
Operation
Operation of the Boiler
Turn on water and power supply.
Open cabinet door and turn main power switch ON. Pilot light ignites and water begins to ll boiler - observe water gauge
sight glass to verify that proper water level is reached.
Once the proper water level is reached, the heaters begin to heat the water. Heaters require about 15 minutes to begin
steam generation. The boiler pressure gauge in the cabinet should indicate steam pressure in a range of 9 to 11 psig.
Operating Procedures
CAUTION
The appliance and its parts are hot. Use care when operating, cleaning and servicing the appliance.
With Boiler In Operation Mode
1. Fill kettle with product to desired level.
2. Slowly turn the steam control valve to full open position.
3. The water or food should boil 3 - 4 minutes per gallon. If it does not, then incoming pressure should be checked to
determine that it is adequate to operate the kettle eciently.
4. Regulate steam control valve depending on type of food being prepared.
5. When food is cooked, turn o steam, remove food and clean kettle immediately to prevent residue from drying on
kettle bowl surface.
Shut Down
Turn the Main Power Switch OFF. Open manual drain valve. If unit is supplied with Automatic Blowdown Valve, it will
open, draining the boiler and releasing hot water and steam to the drain.

Direct Steam Kettles Mounted on Electric Boiler Cabinet BaseOperation
CSD-1 Optional Feature
Start-up Procedure
1. Close the manual blowdown valve.
2. Open cabinet door and turn “ON” power switch.
The green pilot light will come “ON.” Water will begin to enter the boiler. When enough water has entered the boiler,
the (amber) “STANDBY” pilot light will come on.
3. Press the “RESET” switch to begin boiler operation.
The “STANDBY” pilot light will go o and the boiler will begin operation.
Normal Boiler Operating Cycle
Water Fill Cycle
On the initial lling of the boiler, the reset switch must be activated to initialize the safety lockout circuit. Once the water in
the boiler has reached the proper level, the level control will stop the ow of water to the boiler. As water is consumed in
the production of steam, the level control will supply additional water to the boiler.
Firing Cycle
The elements are operated by pressure sensing devices. On initial operation, the boiler should reach 11 psi in
approximately 15 minutes. At this point, the operating pressure switch will open, de-energizing the elements. Thereafter
the operating pressure switch will cycle the elements between 9 and 11 psi boiler pressure.
Condensing Drain
A thermostat is located in the drain assembly and is activated by the temperature of steam. The thermostat operates the
cooling solenoid, supplying water to the drain to condense the steam.
Automatic Blowdown Valve
If the unit has an automatic blowdown valve, it is activated when the main power switch is activated. The boiler will be
drained should the main power switch be turned “OFF.”
Safety Lockout Conditions
High Temperature Condition
A high temperature safety device is installed on the boiler. Should the temperature exceed the limit of this device, the
boiler will be shut down and put in a state of lockout. The “TEMPERATURE” pilot light (red), and the “STANDBY” pilot light
(amber), will come on.
High Pressure Condition
A high pressure safety switch is installed on the boiler. Should the pressure exceed the limit of this device, the boiler will
be shut down and put into a state of lockout. The “PRESSURE” pilot light (red), and the “STANDBY” pilot light (amber),
will come on. Should this device fail to operate, the safety relief valve will open.
Low Water Condition
A second low water safety cut o is supplied with the boiler. Should the water level fall below normal operating levels, the
boiler will be shut down and put into a state of lockout. The “LOW WATER” pilot light (red), and the “STANDBY” pilot light
(amber) will come on.

Direct Steam Kettles Mounted on Electric Boiler Cabinet Base Periodic Maintenance
PERIODIC MAINTENANCE
WARNING
Disconnect the unit from the power supply before cleaning or servicing appliance.
IMPORTANT INSTRUCTIONS
Be sure to ush your boiler water level control daily. Failure to follow this procedure can cause the control to malfunction
resulting in serious boiler damage.
The Boiler Water Level Control installed on your boiler requires periodic maintenance. As boiler water circulates into
the oat chamber, sand, scale and other sediment may be deposited in the oat chamber. While the chamber has been
designed with a large accumulation bowl, it is necessary to ush the sediment from the chamber by blowing down the
control so that the accumulation of sediment does not interfere with the movement of the oat in the control.
Control must be ushed at least once a day.
CAUTION
Protect yourself. When ushing control, hot water and steam will ow out of the drain.
When ushing control, note water level in gauge glass, allow the boiler to ll if necessary and also to come up to temperature.
Before ushing control, note that water level in gauge glass is within operating range and the boiler pressure is at least
6 psi. While the boiler is being red, open blowdown valve at bottom of control by rotating the handle counterclockwise
about 1/4 turn to fully open the valve
Opening the blowdown valve also checks the cut-o operation. Float should drop shutting burners o, hot water and
steam will ow out the drain ushing away sediment.
CAUTION
If heater does not shut o during blowdown, immediately discontinue use of appliance and call for service.
Continue draining water for about fteen (15) seconds, from control until water is clean. Manually close valve. Recheck gauge
glass. If water level has dropped signicantly, wait for the boiler to restore water level and pressure and repeat if necessary.
1. Observe that the water in gauge glass is clean and clear. Extreme murkiness in water indicates inadequate water quality.
2. Safety valve should be tripped during operation once a week to assure that it functions properly.
3. Keep all exposed cleanable areas of unit clean at all times.

Cleaning
CAUTION
Do not use cleaning agents that are corrosive.
Your kettle should be cleaned immediately after each use.
1. Ensure that steam supply is OFF.
2. Pre-rinse inside of kettle thoroughly and tilt 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 and rinse thoroughly draining out detergent solution.
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 appliances.
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.
What to Do if Surface Rust Appears
Metal utensils should never be used as they will scratch the surface of the equipment and rust may begin to form. To
remove surface accumulation of rust from the inadvertent use of such utensils, the following procedure may be used.
WARNING
Disconnect the unit from the power supply before cleaning or servicing appliance.
1. Use undiluted white vinegar with a non-abrasive scouring pad (plastic) or cloth on the aected area to remove the rust
stain. The appliance should not be heated and remain at room temperature during the entire cleaning process.
2. If the stain resists removal, additional exposure time with vinegar may be required, to a maximum of one hour.
3. Thoroughly wash all of the vinegar away with fresh clear water. Dry the surface completely and allow one hour before
using the appliance to cook.
Following daily and period maintenance procedures will prolong the life for your equipment. Climatic conditions - salt air -
may require more thorough and frequent cleaning or the life of the equipment could be adversely aected.

Boiler Descaling Instructions
It is recommended that the boiler be checked every 90 to 120 days for scale build up. Regular maintenance should be
carried out at this time.
1. With boiler empty, close manual blowdown valve. If appliance is equipped with Automatic Blowdown, turn water supply
to appliance OFF. Turn power switch ON. This will energize and close blowdown valve.
2. Remove 3/4” pipe plug from tting on left front of boiler.
3. Insert appropriate hose or tube through tting and pour in (1/2) half gallon (U.S.) of CLR Descaling Solution.
If available, use the Optional Deliming assembly DPA-1 available from your dealer.
4. Replace 3/4” pipe plug securely.
5. Open water supply to appliance allowing water to ll boiler to required level.
6. Let appliance cycle, allow two hours for descaling and cleaning. DO NOT TURN ON STEAM to attached appliances
or to upper compartment.
7. Open both the blowdown and low water level control valves for complete drainage. After boiler drains, close
both valves.
8. Turn appliance switch ON. When boiler is completely lled turn power switch OFF. This will rinse and drain boiler.
Appliances with manual blowdown valve must be opened to drain.
9. Complete Step 8 twice to assure boiler is completely rinsed.
10. Appliance is now ready for use.

Calibrate Pressure Switches
Pressure switch range is from 1 to 15 psi.
Adjust all settings to maximum on high signal adjustment screw on pressure switches.
Adjust in the following sequence:
‒ High limit pressure switch.
‒ Operating pressure switch.
‒ Turning screw clockwise to increase, counterclockwise to decrease pressure.
‒ Use relief valve to release pressure from boiler for settling adjustments.
1. HIGH LIMIT PRESSURE SWITCHES
Allow pressure to build until unit shuts o. This should occur at 15 psi. Set the high signal to switch at 14.5 psi on the
gauge and the low signal to 13.0 psi.
2. OPERATING PRESSURE SWITCHES
Set the high signal to switch at 11 psi on the gauge and the low signal to 9 psi.
3. Release pressure in boiler to below 9 psi. Burner will come on. Once pressure has reached 11 psi, burners will shut
o. Repeat this process several times to make sure burners come on at 9 psi and shut o at 11 psi.
Once completed, pressure switches have been calibrated.
