Installation, Operation, and Care of GCO2D & GCO2C GAS CONVECTION OVENS KEEP THIS MANUAL FOR FUTURE USE GENERAL The GCO2D Gas Convection Oven is a single cavity oven and features a solid state thermostat, 1-hour dial timer, and five racks as standard equipment. Additional oven racks are optional. Each oven is equipped with a 25,000 Btu/hr burner and a 1⁄2 HP (0.37 kw) electric motor.
INSTALLATION CODES AND STANDARDS In the United States, Vulcan gas ovens must be installed in accordance with: 1) State and local codes; 2) National Fuel Gas Code, ANSI-Z223.1 (latest edition), available from American Gas Association,1515 Wilson Boulevard, Arlington, VA 22209; 3) ANSI/NFPA 96, Vapor Removal from Cooking Equipment (latest edition), available from National Fire Protection Association, Batterymarch Park, Quincy, MA 02269; and 4) National Electrical Code, NFPA-70 (latest edition).
ASSEMBLING STACKED OVENS FRONT OF TOP OVEN Determine which oven will be on the bottom and place it on its left side, being careful to avoid scratching the finish. Install the four 16 3⁄4" (42.5 cm) legs, using the 24 bolts and lockwashers provided (6 per leg). Remove the two 7/16" (1.1 cm) knockouts on each side of the top cover and place oven in upright position at installation location. Turn the adjustable feet in or out to level the oven front-to-back and side-toside (refer to LEVELING, page 6).
Do not turn the power supply on until after the gas connections have been made and checked for leaks.

FLUE CONNECTION Ventilation requirements will vary with each installation and must comply withVapor Removal from Cooking Equipment, NFPA Standard #96 (latest edition) and with local codes. Considerations to be kept in mind include: • Flue connections should never be made directly to the oven. • The oven should be located under a hood which has an adequate connection to an exhaust duct and extends 6" (15 cm) beyond the oven sides.
LIGHTING THE GCO2D OVEN Open the manual valve. Turn the MASTER switch ON and turn the thermostat to its maximum setting. Both the ON and HEAT lights should be lit. If the HEAT light is not on, make sure the door is closed. After 5 seconds, the spark ignition system will initiate and the solenoid valve will open, allowing gas flow to the burner for a period of 7 seconds.

Gentle Bake Button Selects the gentle bake time setting. A roast time must first be set. The gentle bake time can then be set at the roast time value or less. The gentle bake time will be the portion of roast time to operate in the gentle bake mode. Gentle bake mode will start first. When the gentle bake time has lapsed, the remainder of the roast time will be in the non-gentle bake mode. Use Gentle Bake when cooking delicate product, such as strudel, muffins, cupcakes, meringue pies, etc.

ROAST AND HOLD OPERATION — GCO2C OVEN Roast and Hold cooks the product in two stages. During First Stage Cooking, the oven temperature is regulated by the Roast thermostat for the amount of time set on the Timer. After the lapsed time counts down to 00:00, Second Stage Cooking begins. During Second Stage Cooking, the burners are off as the temperature in the oven declines to the Hold Temperature. The door should remain closed during Second Stage Cooking.
The convection oven is a bit faster than conventional deck-type ovens; temperature settings are lower and cook times are shorter. Since recipes and foods are subject to many variations and tastes, the guidelines regarding times and temperatures in this manual are SUGGESTIONS ONLY. Experiment with your food products to determine the cooking temperatures and times that give you the best results.
