3.0 INTRODUCTION
DESCRIPTION
Model GC-12 (12 gallon capacity) gas fired, 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 distilled 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 reservoir. 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 sufficient 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. See Adding Water in Service section.
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.

4.0 INSTALLATION INSTRUCTIONS
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.
Ventilation must be provided in accordance with local codes, or in the absence of local codes, with
ANSI/NFPA 96 Standard for Ventilation and Fire Protection of Commercial Cooking Operations.
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 liquified 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 connection. 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: Never use an open flame to check for gas leaks. Check all
connections for leaks using soapy water before use.
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.

INSTALLATION
1. Uncrate carefully. Report any hidden freight damage to the freight company immediately.
2. Ideally an exhaust system should be directly above the appliance to exhaust combustion
gases generated by the unit.
3. The appliance is intended for use on noncombustible floors. The minimum clearance from
combustible and noncombustible floor construction is 0" on right side, 0" on left side and 6"
(152 mm) from the back of the flue chimney.
4. Appliance location must allow air supply to unit and obstruction free clearance for air opening
into the combustion chamber.
5. Set the appliance in place and level using spirit level. Level left to right and front to back.
6. Mark hole locations on the floor through the anchoring holes provided in the flanged
adjustable feet.
7. Remove the appliance from installation position and drill holes in locations marked on the
floor. (See installation diagram on Page 4). Insert proper anchoring devices. (Not supplied).
8. Place appliance back in the installation position and Re-level left to right and front to back.
9. Bolt and anchor appliance securely to the floor.
10. Seal bolts and flanged feet with silastic or equivalent compound.
11. Make service connections as indicated.
12. 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. 3/4" diameter pipe may be used to extend to the
floor, but must not be piped directly to a drain. It must be vented to the atmosphere.
13. Check the pressure gauge on the front panel before operating. The reading should be in the
green vacuum zone (below 0 PSI). See “Re-establishing Vacuum” section under Service
Instructions.
