OPERATION
CONTROLS AND INDICATORS
CALIBRATING THE BROIL STABILIZER CONTROL
The 1424/1450 & 1430/1435 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.
ROIL 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 control 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 example, 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.
TROUBLESHOOTING ERROR MESSAGES
- Message Action
- ER 4 Turn power on and off several times. If the message remains, replace control. If the message disappears, the control may need to be reprogrammed. Call Nieco or your local distributor for instructions.

CLEANING INSTRUCTIONS
DAILY CLEANING
Clear broiler of all food product before shutting down to clean. Allow broiler
to cool before handling parts.
-
SHEET METAL PARTS. Remove all trays, drip pans, stripper blades, reflectors, and side panels.
Wash with water and an approved detergent. Sanitize. -
SHAFTS. Clean the drive shafts with the special tool provided.
-
BUN PLATEN. Clean and sanitize the teflon sheets daily.
Do not spray anything on the control box.
WEEKLY CLEANING -
Clean the frame of the broiler as necessary to remove grease build up.
PERIODIC MAINTENANCE
Note: Maintenance should be performed by authorized personnel only.
Always disconnect the power before performing any maintenance on the broiler.
Check the heating elements periodically for signs of wear. Rotating the top
and bottom elements every 6 months will increase the life of the elements, and
improve the performance of the broiler.
The motor uses carbon brushes that will eventually wear out. Replace the
brushes if there is excessive noise or erratic performance from the motor.
Variations in supply voltage can affect the temperature of the broiler.
Overfired elements can cause performance problems and warping. Heating
elements are available in different voltages, so adjustments to cooking
performance are made by using different voltage elements. Contact your
distributor for more information.
Always keep the control box clean and free of grease. Do not spray anything on
the controls.
CONVEYOR BELT REMOVAL
Before beginning, notice the way the belt runs through the broiler. Also notice the direction the knuckles face. Be sure to re-assemble in the same way.
- Run belt until the Master Link is near the front idler shaft.
- Lift shaft and Teflon Blocks up, and slide the blocks out.
- Unhook the Master Link.
To reassemble, reverse the procedure. Be sure to reassemble the belt with the knuckle opening facing away from the direction of travel.
CONVEYOR BELT TENSION
Maintain proper tension on the conveyor belts to prevent jamming. Bearing
spacers (pictured below) are supplied with the broiler to make minor tension
adjustments. Major tension adjustments are made by removing a link or links
from the belt.
The diagram on the left shows the spacer in the stored position. The diagram
on the right shows the spacer behind the teflon bearing tightening the belts.
Belt tension should be checked monthly. To do this, allow the machine to cool, then grip the idler shaft at each end and pull on it. If the shaft and bearings move 3/16” or more, the spacers should be placed behind the bearings to tighten the belts. If the spacers are already behind the bearings, return them to the stored position and remove a link from the conveyor belt.
BROIL BELT PROBLEMS
Interference with stripper blade:
The most common belt problem to be expected is the physical interference of
the belt with the stripper blade. This is caused by bent or warped rods, or
loose belt, and can be fixed by replacing the rods that are causing the
problem. Other causes are bent stripper blades, or utensils jammed in the
belt.
Blocked belts:
When trouble shooting drive problems, it is important to ensure that the belt
is not being blocked. To do this, detach the drive chain and turn the meat
belt by hand. The belt, with the motor detached, should turn freely and
easily. If the blockage has occurred which is preventing the belt from
turning, the blockage should be removed before the drive chain is re-attached.
The drive chain can be easily removed from the drive sprocket (on the motor
shaft) by loosening the mounting bolts and raising the motor.
TROUBLE SHOOTING GUIDE
Identify the problem in the left column, and look for probable causes and
solutions in the right hand columns. Probable causes are listed in “most
likely to happen” order. This sequence should be used to isolate the problem.
Once the cause is found, refer to OPERATION and PARTS AND LOCATION sections
for explanation of function or repair part needed.
