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. - Page 6 INSTALLATION (Continued) 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. Information on the construction and installation of ventilating hoods may be obtained from the standard for “Vapor Removal from Cooking Equipment”, NFPA No.
- Page 7 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"...
- Page 8 2.0 INSTALLATION (Continued) 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).
- Page 9 2.0 INSTALLATION (Continued) PERFORMANCE CHECK The following items should be checked before or within the first 30 days of operation by a qualified service technician. 1. Verify correct gas type against rating plate on unit. 2. Verify correct voltage, cycle and phase against rating plate on unit. 3.

3.0 OPERATION Contact the factory, the factory representative or a local service company to perform maintenance and repairs should the appliance malfunction. CAUTION: If you smell gas during the lighting procedure, immediately shut off the gas supply until the leak has been corrected. WARNING: In the event of main burner ignition failure, a 5 minute purge period must be observed prior to re-establishing ignition source. - Page 11 3.0 OPERATION (Continued) A. Lighting (Continued) If after 36 seconds the burner fails to ignite or the “ignition light goes out, the system goes into Safety Lockout. De-energize the system by setting the thermostat to “OFF” for five minutes and try again. 1.
- Page 12 3.0 OPERATION (Continued) FRONT PANEL CONTROLS 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. (GREEN) IGNITION LIGHT This light is on whenever the main burner gas is on.
- Page 13 3.0 OPERATION (Continued) THERMOSTAT The thermostat selects the desired internal kettle operating temperature. The thermostat must be set at a desired setting in order for the burner to ignite. For Reference: DIAL SETTING PRESSURE GAUGE The pressure gauge indicates the internal operating pressure of the kettle. When cold, the gauge should point to the green vacuum zone.
- Page 14 3.0 OPERATION (Continued) PRESSURE RELIEF VALVE The pressure relief valve is a safety device which prevents the internal kettle pressure from exceeding 50 psi. It should never be tampered with. DAILY OPERATION Daily operation should consist of turning on the power switch and setting thermostat for the desired temperature.
- Page 15 3.0 OPERATION (Continued) 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.

Page 16: Cleaning Instructions
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. - Page 17 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.
- Page 18 4.0 CLEANING INSTRUCTIONS (Continued) 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. 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.
- Page 19 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.

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. Blower wheel inlet and motor air vent should be cleansed if an accumulation of dust or lint is obvious. -
Page 21: Service
6.0 SERVICE GENERAL When any difficulty arises always check that the unit has been connected to the gas supply type and voltage for which it was supplied. This can be done by examining the serial plate on the lower right side of the unit. It will list the gas type and voltage for which the unit was manufactured. - Page 22 6.0 SERVICE (Continued) THERMOSTAT The thermostat adjustment should not be changed. Check the following before changing the thermostat. 1. With kettle cold, the pressure on the pressure gauge should read in the green vacuum zone (25 to 30 inches Hg vacuum). If not, see „Re-establishing Vacuum” section. 2.
- Page 23 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 bottom of the panel. Be sure to support the panel to avoid excessive strain on the wiring.
- Page 24 6.0 SERVICE (Continued) ADDING WATER (Low water light comes on) 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. Lift handle of pressure relief valve to release vacuum in kettle. 3.
- Page 25 6.0 SERVICE (Continued) RE-ESTABLISHING VACUUM Periodically check pressure gauge when kettle is cold. Reading should be in green vacuum zone (below 0 psi). Otherwise air is present and proper heating will not occur. Use the following procedure to remove air and re-establish vacuum: With the kettle empty, turn the thermostat knob to the highest temperature.
