3.0 OPERATION 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. WARNING: In the event you smell gas, shut down equipment at the main shut off valve and contact the local gas company or gas supplier for service.
3.0 OPERATION (Continued) At this time the spark igniter will begin sparking at the burner. If after 4 seconds the burner does not light, the control will attempt to relight the burner two additional times at an interval of about 20 seconds. NOTE: Should the red “COOKING” pilot not come on when the thermostat has been set to the desired setting, the unit has gone in to lock out and a five minute period of complete shut down is required before restarting.
3.0 OPERATION (Continued) FRONT PANEL CONTROLS 1. 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 some time. 2. (Red) Cooking Light This light is on whenever the main burner flames are on. 3. (Amber) Low Water Light All kettles are supplied with sufficient distilled water in the pressurized jacket.
3.0 OPERATION (Continued) DAILY OPERATION Daily operation should consist of turning on the power switch and setting thermostat for the desired temperature. The thermostat will cycle the burners on and off to maintain 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.
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.
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.
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.
4.0 CLEANING INSTRUCTIONS (Continued) STAINLESS STEEL 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.
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) Clean around burner air mixers and louvered panels if grease or lint have accumulated. TWICE A YEAR: (minimum) Have an authorized service person clean and adjust the unit for maximum performance.
6.0 SERVICE GENERAL CAUTION: Operating, testing, and servicing should only be performed by qualified personnel. 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.
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. THERMOSTAT The thermostat has been factory set and should not require adjustment. Adjustment may be made if an operating pressure deficiency has been determined and that the thermostat is the cause. Adjustment is made by using the set screw inside the stem.
5. Pressure in kettle (read pressure gauge on front panel) should reach a maximum of 30 psi and pressure relief valve should not open. Kettle pressure may rise 2 or 3 psi even after burners shut down. 6. Relief valve should not open when kettle pressure is 30 psi. 7. If relief valve opens, reduce setting on pressure switch, cool kettle completely by running cold water through it and repeat steps 3 - 6. 8.
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. 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.
