A. INSTALLATION
PRE-INSTALLATION
Uncrate the broiler, and inspect for shipping damage. Contact the factory if there is obvious damage. Remove
the tape securing the machine parts, and install the parts in their proper location. Refer to the Parts and
Location section of this manual. If you find concealed damage to any part of this unit, contact your freight carrier immediately. The factory warranty does not cover freight damage.
MOUNTING
If the broiler was shipped with a tubular stand, refer to separate tubular stand assembly instructions.
Note: The four legs of the broiler stand are equipped with casters. Always set the brakes on the casters to prevent the broiler from shifting during operation or cleaning.
Adjust the legs on the broiler and the stand so that the broiler is level.
HOOD REQUIREMENTS
This appliance must be installed under a ventilation hood of adequate size and capacity:
Model 824 or 850 800 CFM (1020 CMH)
Model 624 or 650 600 CFM (760 CMH)
The hood should be at least 6" (15.2 cm) larger in all dimensions than the appliance top, and be 12" to 18"
(30.5 cm - 45.7 cm) above the top. Do not obstruct the flow of combustion and ventilation air. An adequate air
supply must be available for safe and proper operation.
Note: See the National Fire Prevention Association booklet on ventilation of cooking equipment. Write
to: NFPA, 470 Atlantic Ave., Boston, MA 02210. Local codes on venting must also be complied with.
CLEARANCE
For proper installation, the minimum clearance from combustible and non-combustible construction is 6" (15.2
cm) from the back and 6" (15.2 cm) from the front of the machine. Keep appliance area free from combustibles.
To facilitate disassembly and service of the unit a minimum of 24" (61 cm) should be allowed on the front of
the broiler as well as the left side.
ELECTRICAL CONNECTION
Power requirements are stated on the unit nameplate and must be connected accordingly. Before starting
broiler, tighten all electrical connections in control box.
Note: This appliance must be electrically grounded in accordance with local codes or in the absence
of local codes, the National Electrical Code, ANSI/NFPA No. 70-1990. In Canada, in accordance with
the Canadian Electrical Code CSA 22.1 part 1, or local codes.
WARNING: This appliance should be connected with a five-pronged grounding plug for your
protection against shock hazard. Be sure to plug directly into a properly grounded five-prong
receptacle. Do not cut or remove grounding prong from plug.
Note:
This appliance cannot be safely operated in the event of a power failure. No attempt should be
made to operate during a power failure. Disconnect power supply before servicing.
PRE-OPERATION CHECK
Be sure that all parts are installed in the proper location. Refer to OPERATION section for lighting procedure.
Start broiler and test for proper operation.

B. OPERATION
CONTROLS AND INDICATORS
CALIBRATING THE BROIL STABILIZER CONTROL
The 824/850 & 824/650 Electric broilers are equipped with a Broil Stabilizer Control that senses when the
broiler is cooking, and increases the temperature when in use. Refer to calibration instructions in this manual
or on the metal label plate on the control box of the broiler. The red light on the control may flash during normal operation. No daily adjustment of the Broil Stabilizer Control is necessary.
FOOD PRODUCT SAFETY
The Nieco broiler is designed to cook food consistently. Careful setting of the conveyor belt speed is
necessary for proper performance. Always test the product to be sure it is cooked properly every
day. Follow established guidelines for food safety and handling.

BROIL TEMPERATURE STABILIZER CONTROL
Electric broilers are equipped with a Broil Temperature Stabilizer Control that senses when the
broiler is being used, and adjusts the temperature to keep the broiler hot during heavy use.
The control consists of two parts - a temperature probe to sense the internal temperature of
the broiler, and the control itself.
CALIBRATING THE BROIL STABILIZER CONTROL
In order to assure proper operation, the Broil Stabilizer Control must be calibrated for operation
in the restaurant. Every broiler will calibrate slightly differently, depending on supply voltage,
ventilation, etc. Follow these step by step instructions when the broiler is new, and once per
month after.
Step 1: Be sure all pieces of the broiler are in place. Make sure the broiler is plugged in and
the exhaust hood is turned on. Turn the broiler on by turning the main power switch to
the right. Turn on the conveyor belts using the motor breaker switch.
Step 2: Set the temperature (bottom number) to 200° F. Use the up or down arrows on the con-
trol to set the temperature. The bottom number is the set temperature and the top number is the actual temperature.
Step 3: Allow the broiler to heat up for 40 minutes. During this time, the actual temperature will
climb. Wait until the actual temperature stabilizes before proceeding.
Step 4: Set the ATC (bottom number) to 200° F higher than the actual temperature. For exam-
ple, if the broiler stabilizes at 700° F, then the proper setting should be 900° F.
WARNING
The broiler can be damaged if this control is not set according to instructions.
