Introduction
DESCRIPTION:
Model FT-12CG (12 gallon capacity) gas red, self-contained, tilting kettle. The kettle has a jacket of double-wall
construction forming a sealed reservoir around the lower
two-thirds of the kettle. The reservoir is charged with dis-
tilled water. The kettle is equipped with a “clean lock” to
hold kettle in cooking position or tilted 105 degrees for
ease of cleaning. The kettle is also equipped with automatic ignition, low water cut off and tilt switch, which,
when activated, shuts down the burner.
BASIC FUNCTION:
The kettle operates by generating steam in the kettle res-
ervoir. The sequence of operation is as follows:
1. Operator turns the power switch to the on position
and sets the temperature control dial to the desired
setting.
2. The red light comes on indicating the kettle is heating.
The green “IGNITION” light comes on indicating that
the ignition and burner are active.
3. Once the kettle reaches the set temperature, the red
“TEMPERATURE” light and the green “IGNITION”
light extinguish.
4. All kettles are supplied with sufcient water in the
jacket. If for any reason the water level falls below
the required amount to operate the kettle, the burner
shuts down and the amber light comes on.
5. The sight glass indicates the water level within the
kettle jacket.
6. The relief valve is a safety feature which prevents
the internal kettle pressure from exceeding 50 PSI. It
should never be tampered with.

WARNING
ELECTRICAL GROUNDING INSTRUCTIONS
This appliance is equipped with a three-prong
(grounding) plug for your protection against
shock hazard and should be plugged directly
into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong
from this plug. (120V units only).
The electrical wiring diagram is located inside the right
hand console of the appliance.
GAS CONNECTION
WARNING
Do not connect the appliance to the electrical
supply until after the gas connection has been
made.
CAUTION
The pipe thread compound used when installing pipes must be a type that is resistant to
the action of liqueed petroleum or propane
gases.
1. The Serial and Rating Plate on the unit indicates the
type of gas your unit is equipped to burn. DO NOT
connect to any other gas type.
2. A 3/4” NPT line is provided at rear for the connec-
tion. The unit is equipped with an internal pressure
regulator which is set at 4” W.C. manifold pressure for
Natural Gas and 10” W.C. for Propane Gas. Use 1/8”
pipe tap on the union elbow assembly located in the
console 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 supply pressure, minimum 6 inch W.C. for natural gas and minimum 12 inch
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 problems, affecting burner operation. Contact you 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.
Use pipe joint compound which is suitable for use with
L.P. on all threaded connections.
Test pipe connections thoroughly for gas leaks.

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 ad 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, to allow the detergent
and water solution to drain.
4. Wipe the exterior of the kettle with a clean, damp
cloth.
Cleaning
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 of your equipment. Climatic conditions salt air - may require more
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 CIRCULATION 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.
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.
