1.
2.0 INSTALLATION WARNING: Do not connect the appliance to the electrical supply until after the gas connection has been made. Installation must conform to local codes, or in 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.
2.0 INSTALLATION (Continued) 2.1 EXHAUST FANS AND CANOPIES: Canopies are set over ranges, ovens, kettles, etc., for ventilation purposes. It is recommended that a canopy extend 6" past the appliance and be located 6'-6" from the floor. Filters should be installed at an angle of 45 degrees or more with the horizontal. This position prevents dripping of grease and facilitates collecting the run-off grease in a drip pan, usually installed with the filter.
2.0 INSTALLATION (Continued) To Install: 1. Uncrate carefully. Report any freight damage to the freight company immediately. 2. Set the unit in place. Be certain to maintain the minimum clearances from combustibles and non-combustibles. 3. For an appliance supplied with legs, level the appliance using a spirit level. Should flanged adjustable feet be provided, anchor to floor using proper anchoring devices. 4. Seal bolts and flanged feet with Silastic or other equivalent compound. 5.
2.0 INSTALLATION (Continued) 1.0 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. 2.0 A ¾” NPT line is provided at rear for the connection. Each compartment is equipped with an internal pressure regulator set at 3.5" W.C. manifold pressure for natural gas and 10" W.C. for propane gas. Use c” pipe tap on the burner manifold for checking pressure. An adequate gas supply is imperative.
2.0 INSTALLATION (Continued) PLUMBING CONNECTIONS: NOTICE: Plumbing connections must comply with applicable sanitary, safety and plumbing codes. Two water lines are provided. Connect water supply lines to the 3/8" copper tubes at the rear of the steamer. One line is for supply of water to the generator and one for cold condensate water to condense live steam entering the drain line. DRAIN CONNECTIONS: Appliance drain is 2 inch pipe size. Provide open air gap type drain.
INSTALLATION (Continued) WATER CONDITIONING: It is important that the water supplied to the generator be softened to no more than 2.0 grains of hardness and have a pH of 6 to 7.5. This degree of hardness can be easily obtained with the use of a properly maintained water softener. The use of a water meter will determine the water consumption and when the water softener needs regeneration or recharging. Failure to comply with these water condition standards may void the warranty.
3.0 PERFORMANCE CHECK CAUTION: The appliance and its parts are hot. Use care when operating, cleaning and servicing the appliance. Once the steamer is installed and all mechanical connections have been made, thoroughly test the steamer before operation. 1. Check that proper water, drain and electrical and gas connections have been made. 2. Turn main power switch ON. 3. Check that “Ignition” light comes on and cycles “ON” and “OFF”. 4.
4.0 OPERATION INSTRUCTIONS CAUTION: If you smell gas during the lighting procedure, immediately shut off the gas supply until the leak has been corrected. LIGHTING Do not attempt to operate this unit in the event of a power failure. 1. Ensure power, gas and water supply is on. 2. Turn power switch “ON”. 3. Steam generator tanks will begin filling with water. 4. Once proper water level has been reached, the ignition light will come on and should remain on. 5. Cooker is now ready for use.
4.0 OPERATION INSTRUCTIONS (Continued) 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. WARNING: When this appliance is installed with casters and is connected to the supply piping by means of a connector for moveable appliances, a restraint to prevent damage to the connector or quick disconnect device should have been installed.
Ignition Light When lit, indicates ignition at the pilot. NOTE: Each cooking compartment has its own steam generator and controls and can be operated independently. SHUTDOWN STAND BY 1. Set Timer to “OFF” position and leave door slightly open. COMPLETE SHUTDOWN 1. Set timer to “OFF” and turn power switch “OFF”. Steam generator will drain automatically. 2. Turn water supply “OFF”. 3. Close manual gas shut off valve. 4.
4.0 OPERATION INSTRUCTIONS (Continued) PREPARATION Prepare vegetables, fruits, meats, seafood and poultry normally by cleaning, separating, cutting, removing stems, etc. Cook root vegetables in a perforated pan unless juices are being saved. Liquids can be collected in a solid 12" x 20" pan placed under a perforated pan. Perforated pans are used for frankfurters, wieners and similar items when juices do not need to be preserved. Solid pans are good for cooking puddings, rice and hot breakfast cereals.
5.0 MAINTENANCE NOTICE: Contact the factory, the factory representative or local service company to perform maintenance and repairs. WARNING: Disconnect the power supply to the appliance before cleaning or servicing. CAUTION: The appliance and its parts are hot. Use care when operating, cleaning and servicing the appliance. CAUTION: Live steam and accumulated hot water in the compartment may be released when the door is opened.
5.0 MAINTENANCE (Continued) WEEKLY (or more often if necessary): 1. Clean exterior with a damp cloth and polish with a soft dry cloth. 2. Use a non-abrasive cleaner to remove discolorations. 3. Clean around burner air mixer and orifice if lint has accumulated. It is NOT RECOMMENDED to use cleaning agents that are corrosive.
5.0 MAINTENANCE (Continued) Soil and burnt 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. NEVER USE A WIRE BRUSH, STEEL SCOURING PADS (EXCEPT STAINLESS), SCRAPPER, FILE OR OTHER STEEL TOOLS.
6.0 DELIMING PROCEDURE CAUTION: Read and follow instructions on the CLR bottle. Use plastic or rubber gloves to avoid skin contact. If CLR comes in contact with skin, rinse with clean water. 1. Completely drain steam generator by setting on/off switch to “OFF”. Set cooking timer to 0. 2. Set on/off switch to DELIME. 3. Unscrew deliming port located in front of generator. Screw in the supplied deliming funnel. Make sure funnel is in upright position.
7.0 TROUBLESHOOTING Burners do not come on: 1. Gas supply to unit is “OFF”. 2. Power Switch is not turned “ON”. 3. Steam generator probe not sensing the water level, will not call for ignition. 4. Ignitor not functioning. 5. Gas combination supply valve not “Opening”. Burners produce carbon deposits: 1. Wrong orifice size. 2. Wrong gas supply. 3. Incorrect pressure at supply. Water flows into cooking compartment: 1. Short circuit between operating level probe and body inside steam generator. 2.
7.0 TROUBLESHOOTING (Continued) Water accumulates in the compartment: 1. Compartment drain clogged. Water flows into drain during shut down: 1. Condensate valve does not close. Check thermostatic cooling valve body for foreign particles or damage. Water not being supplied to steam generator: 1. Water supply is “OFF”. 2. Supply water pressure too low. 3. Defective water fill solenoid valve. 4. Probes shorted or not sensing water, thereby not operating fill solenoid valve. 5.
