Equipment Description FIRING RATE, BTU/hr 5G-KTT, 10G-KTT 5G-KTC, 10G-KTC 10G-KTT, 12G-KTT 10G-KTC, 12G-KTC 31,000 52,000 KTT-G and KTC-G models are stainless steel, steam-jacketed, table top mounted kettles with a self-contained, gas heated steam source. The KTC has a crank tilt hand wheel, and the KTT has a handle that allows the operator to manually tilt the kettle. The kettle body is welded into one solid piece and furnished with a reinforced rim and weldedin “butterfly” shaped pouring lip.
Inspection & Unpacking CAUTION SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT. TAKE CARE TO AVOID PERSONAL INJURY OR DAMAGE TO THE UNIT BY STAPLES LEFT IN THE WALLS OF THE CARTON. CAUTION THIS UNIT WEIGHS BETWEEN 214 AND 240 POUNDS (98 TO 109 Kg) DEPENDING ON SIZE. INSTALLER SHOULD USE PROPER EQUIPMENT TO LIFT SAFELY. The unit arrives completely assembled, except for the tilting handle on hand tilt models which is shipped inside the kettle.
Installation WARNING THE KETTLE MUST BE INSTALLED BY PERSONNEL QUALIFIED TO WORK WITH GAS, ELECTRICITY AND PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT. The kettle should be installed in a ventilated room for efficient performance. Items which might obstruct or restrict the flow of air for combustion and ventilation must be removed. The area directly around the appliance must be cleared of any combustible material. 1.
Installation 8. Adequate space for proper servicing and operation is required. DO NOT block any air intake spacings to the combustion chamber or obstruct air flow. 9. After the kettle has been connected to the gas supply, check all gas joints for leaks. A soap solution or other suitable gas leak detector should be used. Do not use flame when checking for leaks. 10.
Initial Start-Up IMPORTANT BE SURE ALL OPERATORS READ, UNDERSTAND AND FOLLOW THE OPERATING INSTRUCTIONS, CAUTIONS, AND SAFETY INSTRUCTIONS CONTAINED IN THIS MANUAL. WARNING DO NOT STAND ON OR APPLY UNNECESSARY WEIGHT OR PRESSURE ON THE KETTLE FRONT OR POURING LIP. THIS COULD RESULT IN THE OVERLOAD AND FAILURE OF THE TILT MECHANISM, AND POSSIBLE SERIOUS INJURY AND BURNS TO THE OPERATOR AND OTHERS. After the kettle has been installed, the installer should test to ensure that it is operating correctly. 1.
Operation CAUTION ANY POTENTIAL USER OF THE EQUIPMENT MUST BE TRAINED IN SAFE AND CORRECT OPERATING PROCEDURES. A. WARNING KEEP AREA AROUND KETTLE FREE AND CLEAR OF ALL COMBUSTIBLE MATERIALS. DO NOT ATTEMPT TO LIGHT ANY BURNER WITH A FLAME. CAUTION HEATING AN EMPTY KETTLE MAY CAUSE THE RELEASE OF STEAM FROM THE PRESSURE RELIEF VALVE. B. Controls Operator controls for the kettle are: 1. Manual gas valve which controls the supply of gas from the main to the unit. 2. On-Off (toggle) switch.
Operation WARNING AVOID ALL DIRECT CONTACT WITH HOT FOOD OR WATER IN THE KETTLE. DIRECT CONTACT COULD RESULT IN SEVERE BURNS. 5. Crank Tilt Kettles: The kettle body is tilted using the crank tilt handwheel. Turning the crank clockwise tilts the kettle body; counter-clockwise returns it to an upright position. The kettle body will remain in any tilted position. TAKE CARE TO AVOID CONTACT WITH HOT KETTLE BODY OR HOT PRODUCT, WHEN ADDING INGREDIENTS, STIRRING OR TRANSFERRING PRODUCT TO ANOTHER CONTAINER.
Operation CAUTION DO NOT OVER FILL THE KETTLE WHEN COOKING, HOLDING OR CLEANING. KEEP LIQUIDS AT A MINIMUM OF 2-3” (5-8 CM) BELOW THE KETTLE BODY RIM TO ALLOW CLEARANCE FOR STIRRING, BOILING AND SAFE PRODUCT TRANSFER. Basket Insert: a. An optional kettle basket insert can assist in cooking water-boiled products including eggs, potatoes, vegetables, shell fish, pasta and rice. The nylon mesh liner must be used when cooking product smaller than the mesh size of the basket, which is approximately 1/4” (6 mm).
Sequence of Operation The following “action-reaction” outline is provided to help understand how the kettle works. 1. When the power switch is turned on, it starts the spark igniter and opens the automatic valve for the pilot burner. The spark ignites a pilot flame, which heats the sensor. The sensor then sends a signal to turn off the spark. The flame thereafter acts as a standing pilot until the power is turned off. 2.
