Installation, Operation and Care of SG4D, SG4C, SG6D & SG6C GAS CONVECTION OVENS KEEP THIS MANUAL FOR FUTURE USE GENERAL Model SG4D, SG4C, SG6D and SG6C are equipped with a two-speed 1/2 HP (0.37 kw) electric motor, porcelain interior, and two 30,000 BTU/hr burners as standard equipment. A power level control permits variable burner input from 15,000 BTU/hr to 60,000 BTU/hr. Ovens are furnished with five nickel plated oven racks and have eleven rack positions. Oven cool switch allows rapid cool down.
Carefully unpack oven and place in a work-accessible area as near to its final installed position as possible. Do not use the doors or their handles to lift the oven. LOCATION The equipment area must be kept free and clear of combustible substances. When installed, minimum clearance from combustible construction must be 1" (2.5 cm) at the left side, 4" (10 cm) at the right side, and 6" (15 cm) at the rear.
If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect the restraint prior to turning the gas supply back on. Separate instructions for installing casters to the oven are included with the casters. Assembling the Legs to the Oven BACK The legs must be installed on the bottom of the oven. Position oven on its back, taking care not to scratch or damage it.
Remove the rear panel from the upper oven. Install the two-piece stacking common flue (Fig. 3) with the four screws provided. Replace the upper oven's rear panel. Connect the piping between the upper and lower oven. Pipe compound must be resistant to the action of propane gases. The manual gas valve, located behind the small door in the lower front panel, should remain off until all electrical and gas connections are made and the ovens are ready to be used.
Natural gas pressure regulators are preset for 3.5" W.C. (Water Column) (0.9 kPa); propane gas pressure regulators are preset for 10" W.C. (2.5 kPa). 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. After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air. TESTING THE GAS SUPPLY SYSTEM When gas supply pressure exceeds 1⁄2 psig (3.

Displays [Min:Sec] if the countdown time is less than 1 Hour. Displays Temperature in °F. R&H MODE Indicates the oven is in the Roast and Hold Mode. OVEN READY Indicates the oven is preheated and ready for cooking.
MANUALLY SETTING THE COOK TIME, TEMPERATURE, AND POWER LEVEL To Set the Cook Time • Press the SET button. Press the TIME button. Tine displays to indicate TIME. • Use the Up and Down Arrow keys to increase or decrease the displayed Cook Time (HR:min). • Press the SET button again to save the Time setting in the computer.

Always Set the Temperature Before Setting the Time • Press the SET button. Press the TEMPERATURE button; StPt displays. Use the Up and Down Arrow keys to increase or decrease the Temperature. To save, press the SET button again. At startup, the display will initially show a GROWING BAR. When the oven temperature reaches the Set Point, the set temperature displays.
ROAST AND HOLD OPERATION 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. When the Hold Temperature is reached, cooking is done.
RACK ARRANGEMENTS All models are supplied with five racks and have a maximum operating capacity of six racks per oven. The eleven-position rack supports provide for flexibility and proper rack spacing. The following arrangements are recommended.
