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 - 6 INCHES

BACK - 2 INCHES AT FLUE BOX

FLOORS - 6 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.

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

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).

1. Units with legs - adjust the bottom foot on each leg to overcome an uneven floor.

2. 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.

PART NUMBER 10156R1 6 2006-07-20

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

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 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.

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.

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.

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.

PART NUMBER 10156R1 18 2006-07-20

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

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.
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.

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

6.0 SERVICE (Continued)

The front burner shield may be removed to light the pilot, should pilot ignition not be successful
through shutter opening. The pilot should be adjusted to a blue flame with slightly yellow tip
capable of keeping the safety control open. Turning the inner adjustment screw clockwise to
decrease or counterclockwise to increase the pilot flame. Always replace the cover screw after
adjustment and tighten firmly to ensure proper operation.

Replace the safety shield and screw into place after adjustment has been completed.

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. The large slotted cap must be removed to access the adjustment screw.

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.

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

6.0 SERVICE (Continued)

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:

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 different on different 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.

PART NUMBER 10156R1 22 2006-07-20

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

6.0 SERVICE (Continued)

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.

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 off.

2. Total amount of distilled water contained in jacket is 6 gallons, 110 ounces. Amount of
water to be added in a low water condition is 236 fluid ounces (7 litres).

ADDING WATER (Continued)

3. Lift handle of pressure relief valve to release vacuum in kettle. (Relief valve is at left rear of
kettle.)

4. Remove air vent nut on the elbow located at the rear left of the unit.

5. 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 water level at the sight glass is half way between the minimum and
maximum levels.

6. When sufficient water has been added, replace and tighten the nut. Be sure to seal
threads with a pipe joint compound suitable for steam at 50 psi.

7. Vacuum must be re-established. (See Re-establishing Vacuum.)

INSTALLATION AND OPERATION MANUAL, GAS KETTLE, MODEL GL-30

6.0 SERVICE (Continued)

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
temperature pilot light goes off, open air vent nut one (1) full turn for 20 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 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
with a continuity tester. If the fuse is good, check the main power circuit breaker, which should
be external to the kettle.

OTHER FLAMMABILITY INFORMATION: Violent steam generation or eruption may occur

upon application of direct water stream to hot liquids. Flammable concentrations of vapour can
accumulate at temperatures above 214°F. Liquid mist of this product can burn. Spills of these
organic liquids on hot fibrous insulations may lead to lowering of the autoignition temperatures
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,
coat, pants, boots and gloves). If protective equipment is not available or not used, fight fire
from a protected location or safe distance.
