UNPACKING
IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
Immediately after unpacking the steamer, check for possible shipping damage. If the steamer is found to be damaged,
save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, verify that the type of gas supply (natural or propane) and electrical service agree with the
specications on the rating plate located on the left side panel as you face the front of the braising pan. If the supply
and equipment requirements do not agree, contact your dealer immediately.
Installation
INSTALLATION
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 o valve must be disconnected from the gas supply piping system during any
pressure testing of that system at pressures in excess of ½ psi (3.5 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual manual shut o valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (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-o 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 0 INCHES
BACK 4 INCHES AT FLUE BOX
FLOORS NON-COMBUSTIBLE
All units must be installed in such a manner that the ow of combustion and ventilation air are not obstructed. Provisions
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.
Information on the construction and installation of ventilating hoods may be obtained from the standard for
“Vapor Removal from Cooking Equipment”, NFPA No. 96 (latest edition), available from the National Fire
Protection Association, Batterymarch Park, Quincy, MA, USA, 02269.

Gas Fired Steam Tilting KettlesINSTALLATION
WARNING
All connections must be checked for leaks, after the unit has been put in operation. Use soapy water only for
testing on all gases. Never use an open ame to check for gas leaks.
NOTICE
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance
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.
To Install
1. Uncrate carefully. Report any hidden freight damage to the freight company immediately.
2. The pressure relief valve is located at the right 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.
3. Set the unit in place. Be certain to maintain minimum clearances as stated above.
4. To level the unit use a spirit level in all directions on the top of the kettle (lid up). Adjust the bottom foot on each leg to
overcome an uneven oor.
5. Mark hole locations on oor through anchoring holes provided in anged adjustable feet.
6. Remove appliance and drill holes in locations marked on oor and insert proper anchoring devices.
7. Set unit back in position and re-level left to right and front to back.
8. Bolt and anchor appliances securely to the oor.
9. Seal bolts and anged feet with silastic or equivalent compound.
10. Appliance location must allow air supply to unit and obstruction free clearance for air opening into the combustion chamber.
11. Make service connections as indicated.
12. 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 CONNECTION
The serial plate on the lower right side of the unit indicates the type of gas your unit is equipped to burn. Do NOT connect
to any other gas type.
A 3/4” NPT line is provided at the rear for the connection. Each unit is equipped with an internal pressure regulator
which is set for 4” W.C. manifold pressure for natural gas and 10” W.C. for propane gas. Use 1/8” pipe tap on the burner
manifold for checking pressure.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for
satisfactory performance. A steady pressure, minimum 6” W.C. for natural gas and minimum 11” W.C. for propane gas, is
recommended. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable
drop. Fluctuations of more than 25% on natural gas, and 10% on propane gas, will create pilot problems and aect burner
operating characteristics. Contact your gas company for correct supply line sizes. Purge the supply line to clean out any
dust, dirt, or other foreign matter before connecting the line to the unit. It is recommended that an individual manual shut
o valve be installed in the gas supply line to the unit. Use pipe joint compound which is suitable for use with LP gas on all
threaded connections. Test pipe connections thoroughly for gas leaks.
NOTICE
If this equipment is being installed at over 2,000 feet altitude and was not so specied on order, contact service
department. Failure to install with proper orice sizing may void the warranty.

Gas Fired Steam Tilting Kettles OPERATION
Daily Operation
Daily operation should consist of turning on the main 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 o 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 main power switch
to OFF.
Clean as required or on a daily basis. See “Cleaning” section under MAINTENANCE.
Turning on the main power switch initiates a pilot lighting sequence. 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 o 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 when the thermostat is turned on.
End Use 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 remainder 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.
VENT SYSTEM: At least twice a year the unit venting system should be examined and cleaned.
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 o when not in use.
2. Limit preheat times.
3. Use lid when possible.
4. Maintain equipment.

Gas Fired Steam Tilting Kettles Cleaning
Cleaning
WARNING
Disconnect the power supply to the appliance before cleaning or servicing.
Your kettle should be cleaned immediately after each use or when cooking a dierent 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.
3. Rinse the inside of the kettle thoroughly with clean water. Drain the kettle by tilting or through the tangent draw-o
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.
WARNING
Never spray water into electric controls or components!
CAUTION
Do not use cleaning agents that are corrosive.
WARNING
The equipment and its parts are hot. Use care when operating, cleaning and servicing.
WARNING
If you are cleaning a valve that is assembled to a kettle, be sure the kettle is completely empty of any product.
Draw-Off Valve Cleaning
1. If equipped with a tangent draw-o valve, turn the large hex nut on the draw-o 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-o
tube. Brush vigorously.
2. Replace the valve stem assembly and turn the hex nut until snug. Rinse the kettle with clean warm water.
3. Leave the draw-o valve open when the kettle is not in use.
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.
INSTALLATION & OPERATION MANUAL 10325-SB REV 0 (11/21)
PAGE

OF 32
Gas Fired Steam Tilting Kettles
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 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.
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 vapors 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 dicult 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.

CAUTION
Under normal operating conditions a “try lever test” should be performed every two months. Under severe service
conditions, or if corrosion and/or deposits are noticed within the valve body, testing must be performed more often.
A “try lever test” should also be performed at the end of any non-service period.
CAUTION
Hot, high pressure uid may be discharged from body drain and vent during “try lever” test. Care must be taken
to avoid any bodily contact.
WARNING
Disconnect unit from power supply before cleaning or servicing appliance.
CAUTION
High sound levels may be experienced during “try lever” test. Wear proper safety equipment and exercise extreme
care! Test at, or near, half of the operating pressure by holding the test lever fully open for at least two seconds to
ush the valve seat free of sediment and debris. Then release lever and permit the valve to snap shut.
If lift lever does not activate, or there is no evidence of discharge, turn o equipment immediately and contact a
licensed contractor or qualied service personnel.

GAS PRESSURE REGULATOR
The gas pressure regulator is an integral part of the combination gas control located just behind the lower front access
door. The pressure regulator adjustment is on the lower right side of the gas control. (See Figure 1). The large slotted cap
must be removed to access the adjustment screw.
To check the manifold pressure a pressure gauge (manometer) must be connected to the 1/8” NPT pressure tap on the gas manifold.
With the gas o, connect your pressure indicating instrument to the manifold with a tting appropriate for your instrument.
1. Turn the unit on; with main burners on, read the manifold pressure. The pressure should be 4 inches water column (W.C.)
(±) .2 inches W.C. for natural gas or 10 inches W.C. for propane gas. Adjust the pressure regulator to obtain the appropriate
pressure. Check serial plate on lower right side of unit to conrm exact gas type and manifold pressure for your unit.
When pressure has been correctly adjusted turn unit o. Remove pressure indicating instrument and replace the 1/8” NPT
plug in manifold. Replace regulator cap and close access door.

Thermostat
The thermostat adjustment should not be changed. Check the following before changing the thermostat:
1. With kettle cool, the pressure reading on the pressure gauge should be in the green vacuum zone (below 0 psi). If not,
see “Re-establishing Vacuum” section.
2. Check that the pressure switch is not set too high or too low and causing the out of adjustment condition. A voltmeter
should be used by a properly trained serviceman to determine if the pressure switch or thermostat is actually cycling
the burners. If the pressure switch is found to be the problem, see “Pressure Switch” section.
After verifying that the pressure switch is set and operating properly, the thermostat may be adjusted using the set screw
inside the stem. The thermostat should cycle o at a gauge pressure reading of 30 psi. Turn set screw clockwise to
decrease pressure and counterclockwise to increase pressure.
Pressure Switch
The pressure switch should not be adjusted until it is determined to be the cause of an operating pressure deciency. See
“Thermostat” section to determine if the source of diculty is the pressure switch or thermostat.
The major diculties caused by pressure switch mis-adjustment are:
1. Pressure relief valve opening, especially on preheat from a cold start to 275 degrees Fahrenheit (135 °C). (Pressure
switch set too high.)
2. Burners are being shut down by pressure switch, not the thermostat. (Pressure switch set too low.)
The pressure switch is preset for proper operation from the factory. It is adjusted to the maximum pressure, however
not high enough to cause the pressure relief valve to open. This setting will be slightly dierent on dierent kettles due
to variations in the pressure relief valves. During preheat to the maximum thermostat setting (275 degrees Fahrenheit)
(135 °C), from either a cold condition or a lower temperature setting, the temperature may overshoot the thermostat
setting and shut down the burners by the pressure switch. This is normal, however, after the kettle cycles several times
(empty) the thermostat will begin cycling the unit.
To Adjust Pressure Switch
1. To obtain access to the pressure switch, the front panel must be removed. Remove the screws on either side of the
panel. Be sure to support the panel to avoid excessive strain on the wiring.
2. To increase the pressure setting turn the white ribbed knob clockwise; to decrease the pressure, turn it
counterclockwise. Use the centre of the black ring as an indicator.
3. With the kettle empty and completely cold, bypass the thermostat by moving the single terminal side wire to the
double terminal side connector on the thermostat. Turn kettle on.
4. Pressure in kettle (read pressure gauge on front panel) should reach a maximum of 35 psi and pressure relief valve
should not open. Kettle pressure may rise 3 or 4 psi even after burners shut down.
5. Relief valve should not open when kettle pressure is 40 psi; pressure switch setting is satisfactory.
6. If relief valve opens, reduce setting on pressure switch, cool kettle completely by running cold water through it and
repeat steps 3 - 6.
7. If pressure in kettle is below 30 psi when burners shut o, increase setting of pressure switch, cool kettle completely
by running cold water through it and repeat steps 3 - 7.
8. When adjustment is complete, move wire from shorted terminal on the thermostat back to the appropriate terminal
and replace the front panel.

Adding Water
It may be necessary to replenish water in the jacket when the low water indicator comes on. Do so as follows:
1. Unit should be completely cold and o.
2. Lift handle of pressure relief valve to release vacuum in kettle. (Relief valve is at right rear of kettle).
3. Remove air vent nut on the tee located between kettle and relief valve.
4. Using pure distilled water only, pour the water into the opening. (A funnel will be helpful). Water will enter the kettle
slowly, as air must escape through the same hole. Water should be added until the water level at the sight glass is half
way between the minimum and maximum levels.
5. When sucient water has been added, replace and tighten the nut.
6. Vacuum must be re-established. (See Re-establishing Vacuum).
For reference, the total amount of distilled water contained in each unit, and amount to be added in a low water condition
are listed below:
Model Total Amount of Distilled Water
Amount of Water to be Added
in a Low Water Condition
KTLG-80 16.3 Gallons (61.71 L) 721 Fluid Ounces (21.32 L)
KTLG-100 16.3 Gallons (61.71 L) 721 Fluid Ounces (21.32 L)
Re-Establishing Vacuum
With the kettle completely cold a vacuum of 25 to 30 inches Hg (630 - 730 mm Hg) should be maintained as indicated
in the green zone on the pressure gauge on the front control panel. If at any time the vacuum is not in the green zone,
vacuum should be re-established.
With the kettle empty, turn the thermostat knob to the highest temperature. When the temperature pilot light goes o, open
air vent nut one (1) full turn for 30 seconds and then close and tighten the nut. This should remove the air and any loss in
performance should return.
Should the kettle fail to maintain a vacuum after repeated attempts to establish it, further checks should be made to see
if the pressure relief valve is leaking or if there are any leaks in the pressure relief valve piping, copper lines going to the
pressure switch, pressure gauge or thermostat tting.
Control Circuit Fuses
The control circuit is protected by a 3 amp. fuse which is located inside control panel, top right side above transformer.
Should the unit fail to turn on, check this fuse by removing it and either replacing it or testing it with a continuity tester. If
the fuse is good, check the main power circuit breaker, which should be external to the kettle.

Converting Between Natural and Propane Gas
To convert the kettle from natural gas to LP or LP to natural gas use OEM Conversion Kits. Contact manufacturer or your
authorised service company for the kits part numbers.
To convert gas combination control from one gas to another:
1. Turn o main gas supply to the appliance.
2. Remove the regulator cap screw and pressure
regulator adjusting screw. See Figure 3.
3. Remove the existing spring.
4. Insert the replacement spring with tapered end down.
See Figure 4.
5. Install the new plastic pressure regulator
adjustment screw so that the top of the screw is
flush (level) with the top of the regulator. Turn the
pressure regulator adjustment screw clockwise
six complete turns. This provides a preliminary
pressure setting of about 10 inch (254 mm) W.C.
for LP regulator and 4 inch (102 mm) W.C. for
natural gas regulator.
6. Check the regulator setting either with a manometer or
by clocking the gas meter.
7. Install the new cap screw.
8. Mount conversion label on control.
9. Install control and appliance according to appliance
manufacturer’s instructions.
