Local codes regarding installation vary greatly from one area to another. The National Fire Protection Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction” when it comes to installation requirements for equipment. Therefore, installations should comply with all local codes.
ELECTRIC CONVECTION OVENS INSTALLATION Step 2a: Installation of Legs on Single-Deck Ovens 1. Raise oven sufficiently to allow clearance for the legs to be attached. Use of a lift truck or other mechanical lifting means is recommended. For safety, “shore up” and support the oven with an adequate blocking arrangement strong enough to support the load. (If it is absolutely necessary to rest the oven on its side, rest it on its left side or back side.
INSTALLATION ELECTRIC CONVECTION OVENS Step 2b: Installation of Legs on Double-Deck Ovens Double-deck oven can be shipped either already bolted together, or as two separate ovens to be bolted together after delivery. In either case, the oven that is (or will be) the lower oven will have leg pads already bolted to the bottom corners of the oven. Do the following: 1. Raise oven sufficiently to allow clearance for the legs to be attached. Use of a lift truck or other mechanical lifting means is recommended.
INSTALLATION ELECTRIC CONVECTION OVENS Step 3: Installation of Restraint (Only for Ovens with Casters) NOTICE For an appliance equipped with casters, (1) the installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors for Moveable Gas Appliances, CAN/CGA-6.16, and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.
INSTALLATION ELECTRIC CONVECTION OVENS 2. Install eye-bolt (item “F”) to a frame member on the rear of the equipment. After checking carefully behind the frame member for adequate clearance, drill a 1/4” hole through the frame member. 3. Thread hex nut (item “G”) and slide the washer (item “H”) onto the eye-bolt. Insert the eye-bolt through the 1/4” drilled hole and secure with a washer (item “H”) and nylon lock nut (item “I”). 4.
ELECTRIC CONVECTION OVENS INSTALLATION 6. Lift the top oven and position it on top of the lower oven, as shown in the drawing below. 7. Move to the rear of the ovens and remove the six screws shown as items “A” in the left-hand drawing below. Position the tie bracket (item “B”) as shown in the right-hand drawing below. Re-insert the screws that you just removed through the holes in the tie bracket, but do not tighten them yet.
INSTALLATION ELECTRIC CONVECTION OVENS 8. Insert two bolts (items “A” in the following diagram) up through the top of the lower oven and screw them into the threaded holes in the bottom of the top oven. Tighten these bolts and the screws that you did not tightened in the previous step. 9. Replace the right side insulation, exterior panel, and lower front panel that you removed in steps 4, 5, and 6 of this procedure.
INSTALLATION ELECTRIC CONVECTION OVENS Step 5: Installation of Optional Open Pan Storage on G-Series & SL-Series Ovens The following describes how to assemble the optional open pan storage for G-Series and SL-Series ovens.

Attach each supply wire to the appropriate terminal of the contactor (according to the wiring diagram). 7. Insert the ground wire into the grounding lug and tighten the screw. 8. Check that all connections match the wiring diagram and are tight. 9. Reattach the right-side panel and insulation; and the lower-front panel.
ELECTRIC CONVECTION OVENS OPERATION OPERATION OPERATING THE CONTROLS A convection oven is a different type of oven that offers many features and advantages to the food service operation. The additional capabilities and features of the oven require some learning. However, the operation of the oven is not difficult to understand or control once you have some practice.
OPERATION ELECTRIC CONVECTION OVENS Control Panel of STANDARD Models Power Switch Switch ON to use the oven, switch OFF when done using the oven. ON COOK OFF COOL POWER FAN MODE COOK TIMER (MIN.) Cook Timer Turn knob to set a time duration. An alarm will sound when the timer runs out. The timer is a reminder to the user; the timer does not control the oven. HEAT ON Cook Temperature Control Turn knob to select desired cooking temperature.
ELECTRIC CONVECTION OVENS OPERATION Operation of STANDARD Models Models with Standard Controls operate much like a standard oven: you turn the oven ON and select a cooking temperature. Two additional controls are used to control the fan (as described below). The timer is a reminder to you of when to remove food from the oven. The timer does NOT control the temperature of the oven. To cook, do the following: 1. Turn the oven ON using the Power Switch at the top of the control panel. 2.
OPERATION ELECTRIC CONVECTION OVENS Control Panel of CYCLE/COOK and HOLD Models Power Switch Switch ON to use the oven, switch OFF when done using the oven. ON COOK OFF COOL POWER Time Display Displays time setting. Indicator lights indicate whether the numbers shown represent hours-andminutes or minutes-and-seconds. TIME HOUR/MIN Temperature Display Displays cook-temperature setting.
OPERATION ELECTRIC CONVECTION OVENS Operation of CYCLE/COOK and HOLD Models CYCLE/COOK and HOLD models have electronic controls that enable the oven to cook food at a specified cooktemperature for a specified time period, then enter an optional Hold Mode during which the oven maintains a specified hold-temperature for an indefinite period of time. Whenever the power switch is on, the oven will be in one of two modes.
OPERATION ELECTRIC CONVECTION OVENS If you open the oven doors, the fan and burners will temporarily shut off, and the time display will pause until the oven doors are closed again. For ovens that are equipped with an oven interior light, to turn on the light press and hold the switch located at the bottom of the control panel. During the cook time you can start or stop having the fan cycle on-and-off by pressing the Cycle button.
COOKING HINTS ELECTRIC CONVECTION OVENS COOKING HINTS In a standard (non-convection) oven, the air is relatively still and an insulating layer of moisture surrounds the cooking food product. In a convection oven, the fan-blown circulating air strips away this insulating layer allowing the heat to penetrate faster for quicker baking and roasting. Hence, in a convection oven cooking procedures and techniques may require some modification for successful results.
COOKING HINTS ELECTRIC CONVECTION OVENS COOKING PROBLEMS AND SOLUTIONS If... then... Cakes are dark on the sides and not done in the center… lower oven temperature Cake edges are too brown… reduce number of pans or lower oven temperature. Cakes have a light outer color… raise temperature. Cakes settle slightly in the center… bake longer or raise oven temperature slightly. Do not open doors except to load or unload product.. Cakes ripple… do not overload pans or use batter that is too thin.
