    2. OPERATOR CONTROLS The operator controls for the ovens are located on the Control Box which is on the right side of the oven. The fan, burner, and conveyor switches with the operating instructions are shown in Figure 5. Also nearby are the temperature control, the conveyor control, and the fuse bank, (see Figure 6).
  • Page 8 Figure 6: Right Hand Side Control Panel (All Models) All XLT ovens have a right hand side Control Panel. The fuses are located on the Control Panels and are labeled for their function and replacement part number. It is very important to use only the fuses listed.
  • Page 9 Figure 7: Left Hand Side Control Panel (3270-TS/TS2 and 3870-TS/TS2) 3270-TS/TS2 and 3870-TS/TS2 ovens also have a left hand side Control Panel. This panel houses the fuses for the equipment inside the left hand control box. A second temperature control is also used for controlling the burner on the left half of the oven. This allows for two different temperature zones within these ovens for cooking flexibility, with a maximum delta of 50º...
  • Page 10 Figure 8: Optional Right Hand Control Panel (Split Belt Conveyor) A popular option on the XLT oven is the split conveyor belt. This allows for 2 different conveyor speeds through the oven. Figure 8 shows the right hand control panel when the split belt option is present.

  • Page 11: Operation

    3. OPERATION The XLT oven is a convection oven. It cooks foods by forcing hot air to circulate around the food, thereby increasing the heat transfer rate. Convection ovens generally cook foods faster than conventional ovens. The XLT oven models also have a conveyor that carries food through the oven at a uniform rate.

  • Page 12: Detailed Start-Up Instructions

    3.2. DETAILED START-UP INSTRUCTIONS 1. Turn the Fan switch on (see Figure 5). This turns on a fan that forces air onto the food item and also turns on the temperature control/display. 2. Adjust the temperature controller set-point to desired temperature. Figure 9: Temperature Controller See Figure 9 above to adjust the temperature controller.

    on the location by city, county, and/or state. Obtain information from the authority having jurisdiction to determine the requirements for your installation. Your ventilation hood supplier and HVAC contractor should be contacted to provide guidance. A properly engineered and installed ventilation hood and HVAC system will expedite approval, reduce oven maintenance cost, and provide a more comfortable working environment.

  • Page 22: Hood Interconnection

    5.9.4. HOOD INTERCONNECTION The following is a recommended method of providing an interlock system, (if required); between the ventilation fan in the hood and the XLT gas ovens. The circuit shown will stop the ovens from operating if the ventilation fan fails and also prevent the ovens from starting if the ventilation fan is not first operating.
  • Page 23 Under the NFPA 96 these ovens should be considered bakery type ovens. In the rare event fire protection has been required it is recommended that the fire protection be installed as noted below. This will provide the required protection without affecting oven function or cleaning.
