!
!
EQUIPMENT PREPARATION
The griddle is shipped with protective coatings of oil and/or grease. Remove the griddle plate coating just
prior to its first cooking use. If the griddle is to be shut down for an extended period, put a heavy coat of clean
grease back over the griddle plate.
Wipe the remaining cabinet parts down with a hot, wet cloth to remove any shipping dust and protective oil.
!
!
CAUTION: Care must be exercised not to overheat the griddle plate on initial start up by
setting the controls above normal operating temperature. Overheating may cause the
plate to warp and will carbonize the grease (this will cause sticking).
!
!
CAUTION: This griddle plate is steel, but the surface is relatively soft and can be scored or
dented by carelessly using a spatula. Be careful not to dent, scratch, or gouge the plate
surface. Do not try to knock off loose food that may be on the spatula by tapping the corner
or the edge of the spatula on the griddle surface.
SEASONING
1. Wipe any remaining water off grill with paper towels.
2. Use a 1/9-sized pan to pour a small amount of liquid corn shortening (from bag-in-box) onto grill
surface.
3. Use a dry paper towel to cover entire grill surface with a VERY LIGHT coat of shortening.
4. Caution: Do not use hot shortening from fryers.
5. Coating grill with shortening is called “seasoning” and prevents rusting of grill surface.
6. Pour remaining corn shortening into a fry kettle.
7. Take sandwich board to back room to be washed, rinsed and sanitized.
8. Wipe clean area between board and grill with a sanitized towel. Check entire grill area again.
Also, wipe ledge below grill, surrounding walls and bottom of bun warmer (or MPHC).
9. Take condiment pan and grill cleaning tools to back room to be cleaned and properly stored. C l ea n
grill cleaning tools with hot, soapy water.
10. Return sandwich board and grill guards to grill.
11. Empty grease buckets following “Grease Bucket” procedures, as necessary.

OPERATION
Turning the dial knob (recessed in the front panel) controls the heat of the griddle surface. When a control is
turned on, a signal light directly above the dial will glow. This indicates the griddle is heating in that zone.
The individual controls operate each 12” wide cooking zone. Make sure power is supplied to the unit then
turn the control knob to the desired temperature. When the light is out, with the dial set on a temperature
setting, the griddle plate has reached the desired temperature. The lights will intermittently come on during
cooking cycles to indicate temperature is being maintained. For best results, allow the griddle to heat 20-30
minutes before beginning to cook product.
When setting zones to different temperatures, do not set zones beside each other more than 50ºF apart.
Because of the mass of the griddle plate and conduction of the heat they will tend to reach the same
temperature. When you want zones at greater temperature variation, leave a zone or more between the
cooking zones. Turn off the zone or zones between the two cooking areas. Note: this will effect the
efficiency of the griddle. The heat being supplied will heat the areas between the cooking zones. You can
run the zones not being used at a temperature between the two set points, this will improve the recovery of
the hotter zone.
During idle times during the day, turn the griddle to a lower temperature setting. If you need to prepare
product, the griddle will heat up rapidly; and, holding the griddle at a lower temperature will save energy
costs.
When finished, turn all temperature controls to “OFF.”

CLEANING
IMPORTANT: At the end of each day’s operation, turn all temperature controls to “OFF.”
NEVER clean any electrical unit by immersing it in water.
After each cooking load, scrape the griddle surface with a scraper or rigid spatula to remove excess fat and
food particles.
Once a day, or whenever necessary, thoroughly clean and wipe out grease trough. As necessary during
use, wipe out accumulated material to provide good drainage. Remove the grease receptacle, empty and
wash.
CAUTION: Turn off the griddle and allow it to cool before cleaning. Hot surfaces can burn.
Avoid contacting hot surfaces. !
!
Clean all stainless surfaces with warm soapy water. Use a sponge or soft cloth, wipe clean and dry. Do not
use abrasive cleaners since this might damage the stainless finish. If the stainless steel surfaces become
discolored, scrub by rubbing only in the direction of the finish grain. Never use vinegar or corrosive
cleaner. Do not use steel wool, steel wool may leave particles that can rust and cause pitting. To remove
the control knobs for cleaning, pull straight out. Wash in soapy water. Rinse, dry and replace on the shaft.
KEEP GRIDDLE PLATE SURFACE CLEAN. To produce evenly cooked, perfectly browned griddle
products, keep the griddle free of carbonized grease.
Carbonized grease on the surface hinders the transfer of heat from the griddle surface to food. This results
in spotty browning and loss of cooking efficiency; and, worst of all, carbonized grease tends to cling to the
griddled foods, giving them a highly unsatisfactory and unappetizing appearance. To keep the griddle clean
and operating at peak efficiency, follow these simple instructions.
After each use, clean the griddle with a wire brush or flexible spatula.
Each week, or whenever necessary, clean the griddle surface thoroughly. If desired, use a pumice or
griddle stone over the surface. Rub with the grain of the metal while still warm. A detergent may be used on
the plate surface to help clean it, but care must be taken to be sure the detergent is thoroughly removed.
After removal of the detergent, the surface of the plate should then be covered with a thin film of oil to
prevent rusting. Avoid steel wool. After each thorough cleaning, the cooking surface must be reseasoned.

CALIBRATION
Checking the Grill Thermometer:
1. Fill a meat pan with two inches of water and place it on the chili stove.
2. Place a half-size pan into the meat pan to float in the water.CAUTION HOT
3. Allow the water to come to a boil.
4. Place the thermometer in the half-size pan for five minutes.
5. The thermometer should read 212°F. at sea level. Subtract 1.8°F. for every 1000 feet above sea
level.
6. Adjust the thermometer according to the manufacturer’s instructions.
Calibrating the Grill:
1. Set the grill at the proper setting and allow to heat for at least one hour.
2. Place the grill thermometer directly over the sensing bulbs. (See “Sensing Locations”diagram on
following page). Measure off the grill according to the diagram. Use only these locations for
calibration points.
3. Make a note of the high temperature (when element light turns off) and the low temperature (when
the element light turns on). You can use the work sheet to write down the readings. Get a high and a
low reading for each of the sensing locations.
4. Add the high and low temperatures together for each sensing location and divide by two to get an
average.
5. If the difference between the high and low reading for any of the sensing locations exceeds 30°F.,
call a technician.
6. If the average temperature of a sensing location is within 10°F. of the proper temperature, no
adjustment is needed for that thermostat.
To Adjust a Thermostat:
1. Pull off the knob.
2. Use a small screwdriver to turn the set screw clockwise to decrease temperature, counterclockwise
to increase temperature. A quarter turn is equal to about 18°F. You may have to hold the shaft to
prevent it from turning while adjusting the set screw.
3. Check the high and low temperatures again. Adjust the set screw again if necessary.
4. When finished adjusting the set screw, put a drop of nail polish or appliance paint on the screw head
to keep it from turning.
5. Replace the knob.
6. For grills installed after 1979, there are calibration plates between the control panel and the
adjustment knobs. To adjust these thermostats:
A. Loosen the three screws that hold the calibration plate.
B. Hold the temperature adjustment knob and turn the calibration plate so the indicator arrow
lines up with the average temperature for that section of the grill.
C. Tighten the screws.
