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 side panel of left hand console.
EXHAUST FANS AND CANOPIES: Canopies are set over ranges, ovens and kettles for
ventilation purposes. It is recommended that a canopy extend 6 inches 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 two 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
FLOORS - NON-COMBUSTIBLE
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
side of the unit, as combustion air enters through this area.

2.0 INSTALLATION (Continued)
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 3.5" W.C. manifold pressure for natural gas and 4.0"
W.C. for propane gas. Use 1/8" pipe tap on the downstream side of the combination valve 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.
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.

turning the power switch to “OFF”.
Clean as required or on a daily basis. See “CLEANING INSTRUCTIONS” section.
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 salt water to cook shellfish, be sure to rinse and wash the kettle thoroughly after use.
Bring milk and egg products slowly up to temperature in a cold kettle to prevent product from
adhering to the sides. When preparing milk-based products do not preheat the kettle.
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
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 will seal the juices
in the meat.

4.0 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.

4.0 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.

4.0 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.
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.
Part No. 10280R218 2019-12-18

INSTALLATION AND OPERATION MANUAL, GAS TILTING KETTLE,
MODEL FT-40GLS
4.0 CLEANING INSTRUCTIONS (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.
