Page 16

INITIAL PREHEAT

Prior to putting any range or oven into full time operation at normal cooking temperatures, it must be thoroughly dried out. Moisture absorption in the closed spaces, in the insulation, and even inside the heating elements can cause future trouble if not properly treated.

Griddles

To “dry out” the griddle, set the thermostat to 250°F. Allow the unit to operate at least 15 minutes at this heat level. Set the thermostat to 350°F and allow another 15 minutes to elapse. Set the thermostat to 450°F and allow the unit to maintain the temperature for a minimum of 4 hours. More time may be required if the unit has to operate in a moist environment.

If the unit is out of use for three or more days, a one-hour preheat schedule should be used, especially when exposed to high humidity and/or cool temperatures.

Before any griddle plate can be put into full operation it will need to be properly seasoned. To do this, turn the griddle to 200°F and wait for the red heat indicator lamp to shut off. Once the indicator lamp has shut off, apply a thin coat of highgrade, non-salted vegetable oil t the griddle surface with a metal spatula or towel. Wait approximately five minutes and re-coat any dry spots. Repeat this procedure at 300°F and at 400°F.

French Plates

To “dry out” the French plates, set the 6-heat switch to position three. Allow the unit to operate at least 15 minutes at this heat level. Set the 6-heat switch to position four and allow another 15 minutes to elapse. Set the 6-heat to position six and allow the unit to maintain the temperature for a minimum of 4 hours. More time may be required if the unit has to operate in a moist environment.

INITIAL START-UP

If the unit is out of use for three or more days, a one-hour preheat schedule should be used, especially when exposed to high humidity and/or cool temperatures.

Ovens

To “dry out” the oven, set the thermostat to 250°F and turn on the power switch. Allow the unit to operate at least 15 minutes at this heat level. Set the thermostat to 350°F and allow another 15 minutes to elapse. Set the thermostat to 450°F and allow the unit to maintain the temperature for a minimum of 4 hours. More time may be required if the unit has to operate in a moist environment.

If the unit is out of use for three or more days, a one-hour preheat schedule should be used, especially when exposed to high humidity and/or cool temperatures.

NOTICE

OVEN

The convection oven roasts and bakes in shorter time and at lower temperatures with less shrinkage than conventional commercial ovens.

A blower in the Lang convection oven circulates air within the chamber to heat the entire space evenly and transfer heat efficiently to the product, even with stacked loading.

The airflow continuously removes the thick layer of moist, cool air that otherwise would surround the product. When properly loaded and operated, it maintains this airflow throughout the chamber to eliminate hot spots and roasts or bakes with minimum power consumption at twice the output capacity of a conventional oven.

The power switch on the lower portion of the control panel energizes the fan motor and activates the thermostatically controlled circuit for the oven heating elements. When this switch is in the on position, the red indicator light will illuminate.

Rotating the thermostat control knob from "off" position to selected temperature causes the indicator light to illuminate and closes the contactor that feeds power to the heating elements. This light will cycle "on and off" as the thermostat calls for heat in the oven. The blower, however, operates continuously while the power switch is in the "on" position.

The black control knob operates a damper in the oven vent stack. The damper is open when knob is pulled outward.

Circuit breakers behind the control panel protect the electrical components from overload.

OPERATION

Griddle

Thermostats control 24” x 24” grill plate.

Temperature ranges from 100°-450°F.

Recommended: All heavy and light frying.

Set the thermostat dial at the desired temperature and allow for a thirty-minute preheat time.

The red indicator light will be on until the desired temperature is reached and then shut off. The pilot light will cycle on and off as the elements cycle on and off.

French Plate
