LEG ASSEMBLY
Attach the legs to the body by threading the exposed leg stud into the threaded holes
located on the underside of the unit.
Tighten each leg so that the top face of the leg is pressed firmly against the body bottom.
Do not operate griddle without legs or integrated stand as damage will occur.
LEVELING
Position the griddle in the desired location. Level the griddle by using a wrench to turn
the adjustable feet. You must hold the leg while turning the foot so that it’s attachment to
the griddle is not loosened.
LOCATION
The installation location must be kept free and clear of combustibles. Do not permit air to
blow directly at the griddle. Avoid open windows next to the griddle wherever possible.
Avoid wall-type fans which create air cross-currents within the room.
This griddle is Design Certified for installation on a non-combustible counter with 4” legs,
or combustible floor with 25” high stand.

beyond repair.
3. Remove the fastener near the bottom of the terminal box and slide the enclosure up to expose
knockouts.
4. Connect griddle’s line leads to the supply wires as shown in the applicable wiring diagram. Do
not disturb the griddle wiring.
5. Slide enclosure down and secure with fastener.
6. Lower the griddle top, making sure that it is securely in place.
Since the griddle is not fused, you must connect it to a fused circuit equipped with a
suitable disconnecting means as required by local authorities.

OPERATION
The griddle and its parts are hot. Use care when operating, cleaning
or servicing the griddle.
Disconnect power supply and follow lockout / tagout procedures
before cleaning and servicing the appliance.
BEFORE FIRST USE
It is recommended that you clean your Vulcan RRE griddle thoroughly with a mild soap
and water. Rinse the griddle surface thoroughly with water and wipe dry with a soft clean
cloth.
SEASONING THE GRIDDLE
Before turning the unit ON, apply a high temp. cooking oil– about one ounce per square
foot of surface. Do not use plain vegetable oil as it is not stabilized for high heat and may
cause food stick and result in improperly cooked food. Turn the griddle ON and with a
regular wipe cloth; work the oil into the whole griddle surface for two minutes.
After cleaning your griddle with chemicals, you should repeat the seasoning procedure for
proper cooking.
CONTROLS
Each thermostat independently controls a 12” wide griddle section. When each
thermostat is turned ON, the corresponding red indicator light will illuminate to indicate
that the elements are on for that section. When the griddle plate reaches the desired
temperature set point, the elements will be turned off for that section and the indicator
light will go off. At the end of each day, you must turn all the thermostats to the OFF
position to turn off the unit.
USING THE GRIDDLE
To preheat, set the thermostats for the desired temperatures 10-12 minutes before
cooking.
A uniform and systematic approach to loading the griddle will produce the most consistent
product results.
The griddle plate is a composite material which is engineered to provide a high heat
transfer rate to the food. The top surface is stainless steel and can be scored or dented
by careless use of a spatula or scraper. 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. Do not use hardened steel
spatulas. Use mild steel spatulas with rounded corners.

ZONE COOKING
This griddle features two tubular heating elements in each 12” section Each section is
controlled by an independent thermostat. Each 12” section is a separate cooking zone,
and allows cooking a wide variety of products over a single griddle plate. The chart below
is a suggested usage of zone cooking.
When zone cooking, it is suggested that you start with your lowest temperature setting at
either side of the griddle, increasing the zone temperature as you move up the zone line.
These zone cooking guidelines will vary depending on product temperatures, size and
shape. This guide should be adjusted to suit your product and operational cooking
preference.

CLEANING THE GRIDDLE
The griddle and its parts are hot. Use care when operating, cleaning
or servicing the griddle.
Empty the grease drawer as needed throughout the day and regularly clean at least once
daily.
Clean the griddle regularly. A clean griddle always looks better, lasts longer and performs
better. To produce evenly cooked, perfectly browned griddle products keep the griddle
plate clean and free of carbonized grease. Carbonized grease on the surface hinders the
transfer of heat from the griddle surface to the food, resulting in spotty browning and loss
of cooking efficiency. Carbonized grease tends to cling to griddle foods, giving them a
highly unsatisfactory and unappetizing appearance.
To keep the griddle clean and operating at peak efficiency, follow these procedures:
AFTER EACH USE
Clean the griddle with a griddle scraper during the work shift.
ONCE PER DAY
Thoroughly clean the griddle back splash, sides and front. Turn the griddle off and allow it
to cool down between 275°F-300°F, apply some water and clean it with a griddle scraper.
Remove, empty and wash the grease drawer in the same manner as an ordinary cooking
utensil.
ONCE PER WEEK
Clean the griddle surface thoroughly. A detergent may be used on the plate surface to
help clean it, but be sure the detergent is thoroughly removed by flushing with clear
water.
After removal of detergent the surface of the plate the griddle should be seasoned
according to the instructions in this manual.
Clean stainless steel surfaces with a damp cloth and polish with a soft dry cloth. To
remove discoloration, use a griddle cleaner.
If the griddle usage is very high, consider conducting this weekly cleaning procedure
more than once per week.
Do not use a brick or griddle stone for cleaning.
Do not use water-jet to clean the griddle.
Do not use chlorine sanitizer in contact with griddle. Contact can cause
discoloration, corrosion and permanent damage.
Do not use cleaning agents including Sodium Hydroxide, which is common in
household oven cleaners.
