INSTALLATION
Installation Instructions
INSTALLATION CODES AND STANDARDS
Installation must conform with local codes, or in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural
Gas and Propane Installation Code, CSA B149.1, as applicable.
1. The appliance and its individual shut off valve must
be disconnected from the gas supply piping system
during any pressure testing of that system at pressures in excess of 1/2 PSI (0.03 kg/cm2)(3.5 kPa).
2. The appliance must be isolated from the gas supply
piping system by closing its individual manual shut off
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than
1/2 PSI (0.03 kg/cm2)(3.5 kPa). Electrical grounding
must be provided in accordance with local codes, or
in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.
The electrical diagram is located on the inside of the console control cover.
EXHAUST FANS AND CANOPIES
Canopies are set over ranges, ovens and kettles for ventilation purposes. It is recommended that a canopy extend
6” past appliance and be located 7.5 feet from the oor.
Filters should be installed at an angle of 45 degrees or
more with the horizontal. This position prevents dripping
of grease and facilitates collecting the run-off grease in a
drip pan, usually installed with the lter. A strong exhaust
fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot
ames. Makeup air openings approximately equal to the
fan area will relieve such vacuum. In case of unsatisfactory performance on any appliance, check operation with
exhaust fan in the “OFF” position.
WALL EXHAUST FAN
The exhaust fan should be installed at least 2 feet above
the vent opening at the top of the unit.
CLEARANCES
Adequate clearance must be provided in aisle and at the
side and back.
Adequate clearances for air openings into the combustion
chamber must be provided, as well as for serviceability.
SIDES - 6 INCHES
BACK - 2 INCHES AT FLUE BOX
FLOORS - 6 INCH LEGS OR 8 INCH LEGS
All units must be installed in such a manner that the ow
of combustion and ventilation air are not obstructed. Pro-
visions for an adequate air supply must also be provided.
Do not obstruct the lower front or right side of the unit, as
combustion air enters through these areas. The bottom of
the control area must also remain unobstructed.
TO INSTALL
1. Uncrate carefully. Report any hidden freight damage
to the freight company immediately.
2. Set the unit in place. Be certain to maintain minimum
clearances as stated above.
3. To level the unit use a spirit level in all directions on
the top of the kettle (lid up).
a. Units with legs - adjust the bottom foot on each
leg to overcome an uneven oor.
b. Units with casters - loosen the locking nuts, turn
casters in or out as required and tighten locking
nuts.
4. Be certain to leave adequate clearances for cleaning,
maintenance and service.
5. The pressure relief valve is located at the left rear of
the unit. This area should be kept clear and should
not be in an area where operators will normally stand.
The elbow on the relief valve should be turned toward
the oor. A maximum 3 foot, 3/4” diameter pipe may
be used to extend to the oor, but must not be piped
directly to a drain. It must vent to the atmosphere.
6. Check the pressure gauge on the front panel before
operating. If the pressure gauge does not indicate
green vacuum zone (below 0 PSI), see “Re-establishing Vacuum” section under SERVICE, after completing installation instructions.

GAS CONTROL INSTRUCTIONS
Appliance does not require “Lighting” the pilot with a
ame.
START-UP
1. Turn thermostat to “OFF” position and power switch
to “OFF” position.
2. Open control panel access door located on right side
at bottom.
3. Turn dial on combination control to “ON” position by
rotating control knob counterclockwise.
NOTE: Any gas service valves exterior to the unit
should be open.
4. Turn “POWER” switch to “ON” position.
Gas Start-up and Shutdown
SHUTDOWN
Standby
1. Place power on switch and thermostat to “OFF” position.
Complete
1. Place power on switch and thermostat to “OFF” position.
2. Turn dial on combination control from “ON” position to
“OFF” position.
3. Turn any main gas service valves supplying gas to
“OFF” position.
Relighting
1. Turn power switch to “ON” position.
It should be noted that the pilot and electronic ignition do
not cycle with the thermostat. A standing pilot is automatically established and monitored each time the power
switch is turned ON. If the pilot is ever extinguished by a
momentary external interruption, the spark igniter will automatically relight it without disturbing the cooking cycle,
unless lockout occurs.
SPARK IGNITER FAILURE
In the event the spark igniter module fails the unit may
still be operated by carefully following these instructions.
1. Turn thermostat to OFF position; completely counterclockwise.
2. Turn power switch to OFF position.
3. WAIT A MINIMUM OF 5 MINUTES BEFORE PROCEEDING.
5. Set “COOK TEMP” to desired setting. The red
“COOKING” pilot will be on until desired setting has
been reached.
6. At this time the spark igniter will begin sparking at the
pilot until the pilot is ignited, or for ninety seconds (an
audible clicking sound will be evident).
7. When the pilot is ignited the spark igniter will automatically stop and within 15 seconds main burner gas
will come on. If ignition does not occur, after a total of
ninety seconds, the unit will lockout, shutting off all
gas although the spark igniter will continue to spark.
New installations (where there may be a considerable
amount of air in the gas line) may require the unit
to be turned off and immediately back on numerous
times after each lockout period until the air is purged
from the gas line.
4. Turn dial on combination control to ON position (if not
already on).
5. Turn power switch to ON position.
6. Wait two minutes and ten seconds and then immediately light pilot with long match or taper.
7. After 10 - 15 seconds gas valve will allow main burner
gas to ow when thermostat is turned on.
8. The pilot will now stay ignited as long as the power
switch remains ON. If power switch is turned OFF,
repeat the above instructions. It is intended that the
unit be operated in this manner only in emergency
situations and only while it is attended (do not leave
pilot lit overnight; shut off power switch). A qualied
serviceman must be called promptly.

OPERATION
Front Panel Controls & Operating Tips
Power Switch
This switch turns the main power to the unit on and off. It
must be turned on to heat the kettle. It should be turned
off when the kettle will not be in use for long periods.
(Red) Cooking Light
This light is on whenever the main burner gas is on. On
units with standing pilots this light may be on without the
burners being on if the pilot is extinguished. See lighting
instructions.
(Amber) Low Water Light
All kettles are supplied with sufcient distilled water in the
pressurized jacket. If at any time the water level falls be-
low that required for proper operation, the kettle will not
heat and this light will come on. See “Adding Water” section of service instructions.
Thermostat
The thermostat selects the desired internal kettle operating temperature.
Pressure Gauge
The pressure gauge indicates the internal operating pressure of the kettle. When cold, the gauge should be in the
green vacuum zone. If it is not, refer to “Re-establishing
Vacuum” section of service instructions. Under normal
operation with the kettle empty (thermostat set at 275 degrees Fahrenheit) the pressure shall reach 30 psi. When
loaded the pressure may be considerably less.
Sight Glass
The sight glass indicates the minimum and maximum
water level within the kettle. If water level falls below
minimum level more distilled water should be added. See
“Adding Water” section of service instructions.
Pressure Relief Valve
The pressure relief valve is a safety device which prevents the internal kettle pressure from ever exceeding 50
psi. It should never be tampered with.
DAILY OPERATION
Daily operation should consist of turning on the power
switch and setting the thermostat for the desired temperature.
It is recommended the kettle be preheated prior to use.
Milk or egg based products should be placed in the kettle
before heating, however, to prevent sticking. The kettle is
preheated when the cooking light goes off the rst time.
At the end of each day, or if the kettle will not be used for
some time, shut the unit down by turning the power switch
to OFF.
Clean as required or on a daily basis. See “Cleaning” section under MAINTENANCE.
Appliances equipped with casters have been installed
with a restraint to limit their movement to prevent damage to the gas supply connecting system. If disconnection
of this restraint is necessary to move the appliance for
cleaning, etc., reconnect it when the appliance is moved
to its originally installed position.
Turning on the power switch initiates a pilot lighting se-
quence. The spark igniter will begin sparking. The spark
igniter will spark until the pilot is ignited. After ninety seconds lockout will occur. Lockout shuts down all pilot (and
main burner) gas ow although the spark igniter will continue to spark. The power switch must be turned off and
back on to restart the pilot lighting sequence once lockout
has occurred.
If the pilot blows out during operation, the unit will go
through the same sequence to re-ignite itself.
Once the pilot is ignited, main burner gas will ow if the
thermostat is turned on.
END USER TIPS
For easier cleaning add cold water to the kettle immediately after removing contents.
When preparing foods containing vinegar or tomatoes, or
those which have a high salt content, clean the kettle immediately after using to prevent pitting.
Do not use salt to clean the kettle. This will scratch the
surface.
If using saltwater to cook shellsh, be sure to rinse and
wash the kettle thoroughly.
Bring milk and egg products slowly up to temperature in a
cold kettle to prevent product adhering to the sides.
When planning actual cooking capacity, allow room at top
for stirring without spilling.
When preparing puddings from a mix, place the powder in
a cold kettle, add a small amount of the liquid, and stir to
form a thin paste. Turn on the kettle and add the remain-
der of the liquid. Continue as per recipe instructions.
When browning meat bring the kettle up to temperature
before adding. This seals in the juices in the meat.
GAS SAVING TIPS
Use these reminders to help develop energy-saving procedures and habits. Using less natural or propane gas
saves energy as well as money.
1. Turn off when not in use.
2. Limit preheat times.
3. Use lid when possible.
4. Maintain equipment.
OPERATION
8
WARNING
Disconnect the power supply to the appliance
before cleaning or servicing.
WARNING
Never spray water into electric controls or
components!
Cleaning
Monthly
1. Clean around burner air mixers, louvered panels and
pilots if grease or lint have accumulated.
Twice a year (minimum)
Have an authorized service person clean and adjust the
unit for maximum performance. At least twice a year the
unit venting system should be examined and cleaned.
WARNING
The equipment and its parts are hot. Use care
when operating, cleaning and servicing.
WARNING
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 life of the appliance.
Should pitting or corrosion occur this is not
covered by warranty.
CLEANING
Follow the recommended cleaning instructions. Use a
mild detergent, warm water and rinse thoroughly.
Daily
Your kettle should be cleaned immediately after each
use or when cooking a different product. Before cleaning,
check that the kettle has cooled enough to touch it.
1. Rinse the inside of the kettle thoroughly and drain to
remove any food particles.
2. Using a nylon brush, clean the kettle with a mild detergent and water. Never use steel wool or scouring
powder as it will scratch stainless steel. Plain steel
wool can leave small pieces of steel which can rust.
DRAW-OFF VALVE CLEANING
NOTICE
Draw-off valve has a vulcanized rubber coated
stem for better sealing. Do not over tighten.
This may cause the rubber to pull away from
stem and permanently damage it. This is not
covered under warranty.
WARNING
If you are cleaning a valve that is assembled
to a kettle, be sure the kettle is completely
empty of any product.
If equipped with a tangent draw-off valve, turn the large
hex nut on the draw-off valve counterclockwise until it is
completely disengaged from the threads. Grasp the valve
knob and slowly pull out the valve stem and disk. Do not
allow the disk to come in contact with hard surfaces as
it can be damaged and cause valve leakage. Wash the
valve stem, disk and handle. Insert a nylon brush, wet
with detergent and water, into the valve body and tangent
draw-off tube. Brush vigorously.
1. Replace the valve stem assembly and turn the hex
nut until snug. Rinse the kettle with clean warm water.
2. Leave the draw-off valve open when the kettle is not
in use.
3. Rinse the inside of the kettle thoroughly with clean
water. Drain the kettle by tilting or through the tangent
draw-off valve, depending on model, to allow the detergent and water solution to drain.
4. Wipe the exterior of the kettle with a clean, damp
cloth.

MAINTENANCE
Cleaning
DAIRY DRAW-OFF VALVE CLEANING
1. Remove the plug by rst removing the handle, then
turn the plug to line up with the pin and pull with both
hands. It is important to use both hands because the
plug is heavy.
2. Put the plug in a plastic pail that contains a mild soap
solution. A plastic pail works best, as it reduces the
possibility of nicking or scratching the plug. If the plug
gets scratched it may not seal correctly and could
leak.
3. Use a soft cloth or soft brush and clean all surfaces.
4. Using both hands remove the valve from the soap
and rinse well in another plastic pail that contains
fresh water.
5. Wash out the kettle as normal.
6. Once the kettle is washed out, return the plug into the
body. Be sure the plug is inserted into the notch and
turned. Ensure the plug is tight and secure before letting go of it.
If you are cleaning a body and plug assembly, remove
the plug and follow the above procedures. When nished
with the plug, follow the same instructions for washing the
body. Always use both hands when handling the plugs.
Reassemble the plug into the body and use as normal.
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.
CAUTION
Improper use of this procedure may damage
your appliance!
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.
STAINLESS STEEL
To remove normal dirt, grease or product residue from
stainless steel, use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth. Never use vinegar or any other
corrosive cleaner.
To remove grease and food splatters or condensed va-
pours that have baked on the equipment, apply cleanser
to a damp cloth or sponge and rub cleanser on the metal
in the direction of the polishing lines. Rubbing cleanser
as gently as possible in the direction of the polished lines
will not mar the nish of the stainless steel. NEVER RUB
WITH A CIRCULAR MOTION.
Soil and burn deposits which do not respond to the above
procedure can usually be removed by rubbing the surface
with SCOTCH-BRITE™ scouring pads or STAINLESS
scouring pads. DO NOT USE ORDINARY STEEL WOOL
as any particles left on the surface will rust and further
spoil the appearance of the nish. NEVER USE A WIRE
BRUSH, STEEL SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS.
Surfaces which are marred collect dirt more rapidly and
become more difcult to clean. Marring also increases
the possibility of corrosive attack. Renishing may then
be required.
TO REMOVE HEAT TINT
Darkened areas sometimes appear on stainless steel surfaces where the area has been subjected to excessive
heat. These darkened areas are caused by thickening
of the protective surface of the stainless steel and is not
harmful. Heat tint can normally be removed by the foregoing, but tint which does not respond to this procedure calls
for a vigorous scouring in the direction of the polish lines
using SCOTCH-BRITE™ scouring pads or a STAINLESS
scouring pad in combination with a powdered cleanser.
Heat tint action may be lessened by not applying or by
reducing heat to equipment during slack periods.
All food contact surfaces must be thoroughly drained and
ushed prior to cooking in the kettle.
CONTROL PANEL
The textured control panel should be cleaned with warm
water and mild soap. Never use an abrasive cloth or steel
wool. Never use cleaning solvents with a hydrocarbon
base.
