Installation, Operation, and Care of MODEL GCO2D AND GCO2C GAS CONVECTION OVENS KEEP THESE INSTRUCTIONS FOR FUTURE USE Your Vulcan Gas Convection Oven is produced with quality workmanship and material. Proper installation, usage and maintenance of your oven will result in many years of satisfactory performance. Vulcan-Hart Company suggests that you thoroughly read this entire manual and carefully follow all of the instructions provided.
INSTALLATION UNPACKING Immediately after unpacking the oven, check for possible shipping damage. If this oven is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Prior to installation, verify that the electrical supply and type of gas supply (natural or propane) agree with the specifications on the oven data plate, located on the inside of the top front cover. Do not use the door or its handle to lift the oven.
NOTICE: When the oven is mounted on casters, it must be installed with the casters supplied, a connector (not supplied by Vulcan-Hart) complying with either ANSI Z21.69 (latest edition) or CAN/CGA-6.16 (latest edition), and a quick-disconnect device complying with either ANSI Z21.41 (latest edition) or CAN1-6.9 (latest edition). It must also be installed with restraining means to guard against transmission of strain to the connector, as specified in the appliance manufacturer’s instructions.
Remove the two 7⁄16" (11.1mm) 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-to-side (see LEVELING on page 6). Remove right-hand side panels from both ovens. Remove welded plate from bottom of upper oven (Fig. 3). Install the two locating studs (included in the leg stack set) into screw plates on underside of upper oven (Fig. 3).
ASSEMBLING THE OVEN TO THE STAND Unpack the oven and stand. Position oven on its back, taking care not to scratch or damage it. The gas pipe connection protrudes beyond the back; provide for this when the oven is tipped back by resting it on suitable spacers (2 x 4's etc.). Install the two locating studs (included in the stand carton) into the screw plates on the underside of the oven (see Fig. 3).
A gas shutoff valve is supplied with each oven and is located at the bottom of the control panel. No tools are required to access this valve. Connect the oven(s) to the gas line after leveling. The gas supply line must be at least the equivalent of 3 ⁄4" (19mm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt and piping compound. WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
OPERATION CONTROLS — MODEL GCO2D (Fig.

When gentle bake time elapses, the remainder of the roast time will be in the nongentle bake mode. Use when cooking delicate product, such as strudel, muffins, cupcakes, meringue pies, etc.
ON/OFF/OVEN COOL SWITCH 1. ON turns oven control circuits on. 2. OFF turns oven control circuits off. 3. OVEN COOL allows the fan motor to run with the doors ajar to speed oven cooling. GAS VALVE When ON, allows gas to flow to the ignition system. LIGHTING THE GCO2C OVEN 1. Turn manual gas valve ON. 2. Push ON/OFF/OVEN COOL switch to the ON position and set THERMOSTAT to its maximum setting. The HEAT light should come on. If HEAT light is not on, make sure the door is closed. 3.
Cooking 1. Open doors and load the product into the oven. Place pans in the center of the racks. Close doors. 2. Set ROAST temperature and time. Set HOLD temperature and GENTLE BAKE time, if desired. GENTLE BAKE time may not 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.
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 doors should remain closed during Second Stage Cooking.
PROPER UTENSILS The use of proper utensils can enhance oven operation. Medium- and lightweight pans are recommended since it is more economical to bake with lighter pans. Meats should be roasted in shallow pans deep enough to hold all juices and allow free air circulation. CONSERVING ENERGY • • • • • • • Turn off unused equipment. Adjust menu patterns and cooking/baking schedules for optimum equipment use. Reduce thermostat settings in slack periods since gas equipment heats up and recovers quickly.
