be no solid drain connection; an “open gap” between the boiler and the floor drain is
required.
10
3.0 OPERATING INSTRUCTIONS
For CSD-1 equipped boilers, see section 4.0 CSD-1 Optional Feature for proper
operating instructions.
BOILER CONTROLS (Inside Cabinet)
Main Power Switch - ON fills the boiler tank and turns the boiler heaters on. You
should allow 20 minutes to fill the tank and generate steam.
- OFF shuts off 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 psig during operation; 0 psig 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 Water
Quality Statement, page 4).
Water Level Control - While boiler is ON, briefly open the water level control valve
once a day to remove any sediment that might accumulate.
(See page 14 for detailed instructions.)
Safety Valve - This valve will release (pop off) if the boiler has too much
pressure. Once a week, this valve should be tripped during
operation to make sure it functions properly.
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 fill 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.
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.
11
4.0 CSD-1 OPTIONAL FEATURE
OPERATING, TESTING, SERVICING AND CLEANING INSTRUCTIONS
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 off and the boiler will begin operation.
Normal Boiler Operating Cycle
Water Fill Cycle
On the initial filling 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 flow 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.
12
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 off 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.
13
5.0 PERIODIC MAINTENANCE
CAUTION: Protect yourself. When flushing control, hot water and
steam will flow out of the drain.
Be sure to flush 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 float chamber, sand, scale and other sediment may be
deposited in the float chamber. While the chamber has been designed with a large
accumulation bowl, it is necessary to flush the sediment from the chamber by blowing
down the control so that the accumulation of sediment does not interfere with the
movement of the float in the control. Control must be flushed at least once a day.
When flushing control, note water level in gauge glass, allow the boiler to fill if
necessary, and also to come up to temperature.
Before flushing 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 fired, 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-off operation. Float should
drop shutting elements off, hot water and steam will flow out the drain flushing away
sediment.
14
PERIODIC MAINTENANCE (Continued)
CAUTION: Take extra caution when blowing down water level
control or tripping safety valve as extreme hot water and live steam
are present.
CAUTION: If heater does not shut off during blowdown, immediately
discontinue use of appliance and call for service.
Continue draining water for about fifteen (15) seconds, from control until water is clean.
Manually close valve. Recheck gauge glass. If water level has dropped significantly,
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.
DESCALING BOILER
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 fitting on left front of boiler.
3. Insert appropriate hose or tube through fitting and pour in (½) half gallon (U.S.) of
CLR Descaling Solution.
4. If available, use the Optional Deliming assembly DPA-1 available from your dealer.
15
DESCALING BOILER (Continued)
WARNING: At least twice a year have an authorized service person clean and
adjust the unit for maximum performance.
NOTE: Pressure switches are factory set. Calibration is only required if
pressure switches are replaced or if adjustment is required.
5. Replace 3/4" pipe plug securely.
6. Open water supply to appliance allowing water to fill boiler to required level.
7. Let appliance cycle, allow two hours for descaling and cleaning. DO NOT TURN ON
STEAM to attached appliances or to upper compartment.
8. Open both the blowdown and low water level control valves for complete drainage.
After boiler drains, close both valves.
9. Turn appliance switch ON. When boiler is completely filled turn power switch OFF.
This will rinse and drain boiler. Appliances with manual blowdown valve must be
opened to drain.
10. Complete Step 8 twice to assure boiler is completely rinsed.
11. Appliance is now ready for use.
ADJUSTMENTS:
TO 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.
16
TO CALIBRATE PRESSURE SWITCHES (Continued)
Adjust in the following sequence:
1. High limit pressure switch.
2. Operating pressure switch.
3. Turning screw clockwise to increase, counterclockwise to decrease pressure.
4. Use relief valve to release pressure from boiler for settling adjustments.
1. HIGH LIMIT PRESSURE SWITCHES
Allow pressure to build until unit shuts off. 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 off. Repeat this process several times to make
sure burners come on at 9 psi and shut off at 11 psi.
Once completed, pressure switches have been calibrated.

7.0 INTRODUCTION - DIRECT STEAM KETTLES
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.

operating, cleaning and servicing the appliance.
CAUTION: Do not use cleaning agents that are corrosive.
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
efficiently.
4. Regulate steam control valve depending on type of food being prepared.
5. When food is cooked, turn off steam, remove food and clean kettle immediately to
prevent residue from drying on kettle bowl surface.
9.0 CLEANING PROCEDURES
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

WHAT TO DO IF SURFACE RUST APPEARS
CAUTION: Improper use of this procedure may damage your
appliance!
NOTICE: Contact the factory, the factory representative or local
service company to perform maintenance and repairs.
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.
1. Use undiluted white vinegar with a non-abrasive scouring pad (plastic) or cloth on the
affected 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 affected.
10.0 PREVENTIVE MAINTENANCE
No preventive maintenance is required other than adhering to the Cleaning Procedure
instructions.
