BEFORE FIRST USE
Before using the oven for the first time, it must be "burned in" to release any odors that might result from
heating the new surfaces in the chamber.
1. Using a clean damp cloth, wipe the inside of the oven, including the racks.
2. Close the oven door, push the ON / OFF / OVEN COOL switch ON, turn the THERMOSTAT to
300°F (
149°C) and allow the oven to cycle for 6 to 8 hours before turning the ON / OFF / OVEN
COOL switch OFF.
USING THE GCO2C OVEN
Preheating
1. Close the oven door. Push ON / OFF / OVEN COOL switch ON. The HEAT light will come on,
indicating that power to the oven is on.
2. Set THERMOSTAT as desired. Refer to SUGGESTED COOKING GUIDELINES for temperatures
and times.
3. Prepare product and place in suitable pans. When READY light comes on, oven has reached
desired preheat temperature.
Cooking
1. Open the door and load the product into the oven. Place the pans in the center of racks. Close
the door.
2. Set ROAST temperature and time. Set HOLD temperature and GENTLE BAKE time, if desired.
GENTLE BAKE time cannot be more than ROAST time. GENTLE BAKE will cycle the fan during
the set time at the beginning of the cooking cycle.
3. Press the START/STOP button to start the cooking cycle.
4. At the end of the cooking cycle, the buzzer will sound continuously if the HOLD mode is OFF. If
the HOLD mode is ON, there will be a short beep at the beginning of Second Stage Cooking (oven
temperature will begin to decline to the HOLD temperature), and a long beep (20 seconds) at the
end of the cooking cycle. (Refer to ROAST AND HOLD OPERATION.)
5. When product is done, open the door and carefully remove cooked product from the oven. Wipe
up any spills.
End of Day
1. Push ON / OFF / OVEN COOL switch to OVEN COOL. Leave door ajar while the fan is on to cool
the oven.
2. When the oven has cooled sufficiently, turn the ON / OFF / OVEN COOL switch OFF and clean
the oven.
