2.0 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 off 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 off 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 floor. 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 filter. A strong exhaust fan tends to create a vacuum in  
the room and may interfere with burner performance or may extinguish pilot flames. 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  
BACK  
-
6 INCHES  
- 2 INCHES AT FLUE BOX  
FLOORS - 6 INCH LEGS OR 8 INCH LEGS  
All units must be installed in such a manner that the flow 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.  
5
 
2.0 INSTALLATION (Continued)  
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 floor.  
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 floor. A maximum 3 foot, 3/4" diameter pipe may be  
used to extend to the floor, 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 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 1" 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 affect burner operating characteristics. Contact your gas company for correct  
supply line sizes.  
6
 
2.0 INSTALLATION (Continued)  
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 off 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.  
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 flame 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.  
NOTICE: If this equipment is being installed at over 2,000 feet altitude and was  
not so specified on order, contact service department. Failure to install with  
proper orifice sizing may void the warranty.  
WATER CONNECTION  
On units equipped with an optional water fill valve connect a water line (minimum 1/4") to the  
valve with a 1/4" NPT female fitting. Units with dual (hot and cold) valves must have the hot  
water line connected to side with the hot water valve (red) and cold water line to the cold water  
valve (blue). Plastic or rubber hose is not recommended, as it may melt against the hot kettle  
side.  
7
 
2.0 INSTALLATION (Continued)  
WARNING: For an appliance equipped with casters, the installation  
shall be made with a connector that complies with the standard for  
connectors for moveable gas appliances, ANSI Z21.69-CSA 6.16  
and a quick-disconnect device that complies with the standard  
for quick-disconnect devices for use with gas fuel, ANSI Z21.41-  
CSA 6.9; adequate means must be provided to limit the movement  
of the appliance without depending on the connector and the quick  
disconnect device or its associated piping to limit the appliance  
movement; the location where the restraining means may be  
attached to the appliance is on bottom of unit directly below relief  
valve.  
If the unit is also equipped with an optional water fill valve it too  
must be installed with a flexible water supply tube, a quick  
disconnect and strain relief.  
WARNING: Do not connect the appliance to the electrical supply  
until after the gas connection has been made.  
1. 120 VAC - 60 Hz - Single Phase.  
Units with this electrical rating are factory supplied with a three-wire cord and three-prong  
plug which fits any standard 120V, three-prong grounded receptacle. A separate 15 amp  
supply is needed for each unit.

4.0 OPERATION  
Contact the factory, the factory representative or a local service company to perform  
maintenance and repairs should the appliance malfunction.  
WARNING: In the event of main burner ignition failure, a 5 minute  
purge period must be observed prior to re-establishing ignition  
source.  
WARNING: In the event you smell gas, shut down equipment at the  
main shut off valve and contact the local gas company or gas  
supplier for service.  
CAUTION: If you smell gas during the lighting procedure,  
immediately shut off the gas supply until the leak has been  
corrected.  
GAS CONTROL INSTRUCTIONS:  
Appliance does not require “Lighting” the pilot with a flame.  
A. STARTUP  
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.  
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  
11  
 
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.  
B. 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.  
12  
 
4.0 OPERATION (Continued)  
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.  
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 flow 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 qualified serviceman must be called promptly.  
13  
 
4.0 OPERATION (Continued)  
FRONT PANEL CONTROLS:  
1. 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.  
2. (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.  
3. (Amber) Low Water Light  
All kettles are supplied with sufficient distilled water in the pressurized jacket. If at any time  
the water level falls below that required for proper operation, the kettle will not heat and this  
light will come on. See “Adding Water” section of service instructions.  
4. Thermostat  
The thermostat selects the desired internal kettle operating temperature.  
5. 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.  
6. 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.  
7. 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.  
14  
 
4.0 OPERATION (Continued)  
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 first 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 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 flow 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 flow 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 shellfish, be sure to rinse and wash the kettle thoroughly.  
15  
 
END USER TIPS: (Continued)  
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 off when not in use.  
2. Limit preheat times.  
3. Use lid when possible.  
4. Maintain equipment.  
16  
 
5.0 MAINTENANCE  
Contact the factory, the factory representative or a local service company to  
perform maintenance and repairs.  
WARNING: Disconnect the power supply to the appliance before  
cleaning or servicing.  
Daily:  
1. Wash exposed cleanable areas.  
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.  
It is NOT RECOMMENDED to 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.  
Follow the recommended cleaning instructions. Use a mild detergent, warm water and rinse  
thoroughly.  
Never spray water into electric controls.  
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.  
17  
 
5.0 MAINTENANCE (Continued)  
CLEANING INSTRUCTIONS  
WARNING: Disconnect the power supply to the appliance before  
cleaning or servicing.  
WARNING: Never spray water into electric controls or components!  
CAUTION: The equipment and its parts are hot. Use care when  
operating, cleaning and servicing.  
CAUTION: Do not use cleaning agents that are corrosive.  
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.  
3. Rinse the inside of the kettle thoroughly with clean water. Drain the kettle by tilting or 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.  
WARNING: If you are cleaning a valve that is assembled to a kettle,  
be sure the kettle is completely empty of any product.  
18  
 
5.0 MAINTENANCE (Continued)  
CLEANING INSTRUCTIONS (Continued)  
DRAW-OFF VALVE CLEANING  
1. 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.  
2. Replace the valve stem assembly and turn the hex nut until snug. Rinse the kettle with  
clean warm water.  
3. Leave the draw-off valve open when the kettle is not in use.  
DAIRY DRAW-OFF VALVE CLEANING  
1. Remove the plug by first 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 finished 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.

5.0 MAINTENANCE (Continued)  
CLEANING INSTRUCTIONS (Continued)  
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 vapours 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 finish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION.  
20  
 
5.0 MAINTENANCE (Continued)  
CLEANING INSTRUCTIONS (Continued)  
STAINLESS STEEL (Continued)  
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 finish. 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 difficult to clean. Marring also increases the  
possibility of corrosive attack. Refinishing 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 flushed prior to cooking in the kettle.

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.  
23  
 
6.0 SERVICE (Continued)  
ADJUSTMENTS  
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 off, connect your pressure indicating  
instrument to the manifold with a fitting 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 confirm exact gas type and manifold pressure for  
your unit.  
When pressure has been correctly adjusted turn unit off. 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 off 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 deficiency. See “Thermostat” section to determine if the source of difficulty is the  
pressure switch or thermostat.  
The major difficulties caused by pressure switch mis-adjustment are:  
24  
 
6.0 SERVICE (Continued)  
PRESSURE SWITCH (Continued)  
1. Pressure relief valve opening, especially on preheat from a cold start to 275 degrees  
Fahrenheit (135EC) (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 different on different kettles due to variations in the pressure relief valves.  
During preheat to the maximum thermostat setting (275 degrees Fahrenheit) (135EC), 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 off, 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.

338 fl. oz. (10 L)  
RE-ESTABLISHING VACUUM:  
With the kettle completely cold a vacuum of 25 to 30 inches mercury column (M.C.) 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 pressure  
gauge reaches 20 psi, turn thermostat off, open the pressure relief valve until pressure gauge  
reads 1 psi, then sharply release it. 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 fitting.  
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  
26  
 
with a continuity tester. If the fuse is good, check the main power circuit breaker, which should  
be external to the kettle.  
6.0 CONVERTING BETWEEN NATURAL AND PROPANE GAS  
WARNING: Fire or explosion hazard can cause property damage,  
severe injury, or death.  
1. Do not attempt to use a gas control set for natural gas on  
propane gas or gas control set for LP gas on natural gas.  
2. When making conversion, main and pilot burner orifices MUST  
be changed to meet appliance manufacturer’s specifications.  
Standard- or slow-opening gas controls may be converted from one gas to another. To convert  
from natural gas to LP use the 393691 LP Conversion Kit that is included with the VR8304M  
Gas Control. To convert from LP to natural gas use the 394588 Natural Gas Conversion Kit  
(order separately). Step-opening gas controls cannot be converted.  
To convert control from one gas to another:

possibly resulting in spontaneous combustion. Container may rupture from gas generation in a  
fire situation.  
EXTINGUISHING MEDIA: Water fog or fine spray, carbon dioxide, dry chemical, foam. Alcohol  
resistant foams (ATC type) are preferred if available. General purpose synthetic foams  
(including AFFF) or protein foams may function, but much less effectively. Do not use direct  
water stream. May spread fire.  
MEDIA TO BE AVOIDED: Do not use direct water stream.  
FIRE FIGHTING INSTRUCTIONS: Keep people away. Isolate fire area and deny unnecessary  
entry. Burning liquids may be moved by flushing with water to protect personnel and minimize  
property damage. Burning liquids may be extinguished by dilution with water. Do not use direct  
water stream. May spread fire. Fight fire from protected location or safe distance. Consider  
use of unmanned hose holder or monitor nozzles. Use water spray to cool fire exposed  
containers and fire affected zone until fire is out and danger of re-ignition has passed.  
Immediately withdraw all personnel from area in case of rising sound from venting safety device  
or discolouration of the container. Move container from fire area if this is possible without  
hazard.  
PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS: Wear positive-pressure self-contained  
breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet,
