2.PLANNING AND INSTALLATION
Congratulations on the purchase of your new
Rosko electric countertop griddle!
To maximize the use and durability of your unit, we recommend that you follow the instructions in this guide.
Installation, operation, and maintenance procedures must be followed for warranty protection to apply.
2.1. CLEARANCE
It is essential to observe the following minimum clearance when planning the unit’s installation
and during the installation.
•Construction with combustible materials:
◽1’’ (27 mm) at the back and on each side of the griddle
•Construction with non-combustible materials:
◽0’’ (0 mm) at the back and on each side of the griddle
•Provide adequate space for the unit operation and maintenance
2.2. RECEPTION AND INSPECTION
This unit has been inspected and verified before shipment. Upon receipt, check immediately for damage
with the delivery person present. If necessary, make your claim immediately.
The warranty is limited to the replacement of defective parts under normal use. No claims will be accepted
for breakage resulting from improper installation, improper operation, or unauthorized service before installation.
Before installation, make sure the specifications of the electric countertop griddle match the type of electric
power supply. Refer to the nameplate on the side of the unit.
Important: Confirm that you have received all the parts included with your griddle model.
All Electric Countertop Griddle Models
Materials included:
•1 griddle
•1 instruction guide

5RO-GCE_GUIDE (12/21)
2.3. LEVEL
WARNING
The griddle must be supported by a heatproof countertop or stand.
Once the unit is in its final position, level the griddle by adjusting the leveling feet. Make sure the griddle is level
in the front-to-back and side-to-side axis. It is recommended to level the unit each time it is moved. Proper leveling
prevents accidents and ensures optimal cooking performance.
NOTE: Always handle the unit with someone else helping. Attempting to do so alone may result in injury.
2.4. FIXATION
WARNING
The unit must be installed with restraints to counteract possible stress on the electrical circuit.
Do not use the connector or power supply wire to restrict the unit movement. Fastening can be done by inserting
the griddle into a battery of equipment or attaching the griddle to the back wall with a ring and a chain shorter
than the power cord.
NOTE: Fastening material is not included.
For installation on a moving surface with wheels, install the mounting device on the base used.
The restriction must also counteract the stress on the connector and the electrical supply wire.
WARNING
Always turn the griddle power off before removing the fastener.

6RO-GCE_GUIDE (12/21)
2.5. CONNECTION
The wire entry for the connection is a 1" knockout hole located at the back of the griddle.
Use a 1" commercial electrical connector (not included) to insert the electrical supply wire into the unit.
The connection must be made by a certified technician or electrician.
WARNING
Installation must meet the requirements of the codes below, where applicable.
•State codes or local codes, or in the absence of local codes:
the National Electrical Code ANSI/NFPA 70;
•Canada local codes, or in the absence of local codes:
the Canadian Electrical Code CSA C22.1.
1. Manually remove the 1" knockout located behind the griddle.
2. Remove the rear unit panel by unscrewing the six (6) fixing screws. (Figure 1)
3. Install and secure the commercial electrical connector (not included) in the hole provided
on the rear panel. (Figure 2)

4. To reach the terminal block, remove the grease drawer, unscrew the four (4) bolts in front of the unit
and remove the two (2) front panels. (Figure 3)
5. Insert and secure the correct length of unsheathed wire in the connector to direct it to the terminal block
located on the front of the unit.
6. Make sure the end of the wire fits into the wire grommets before it reaches the terminal block. (Figure 4)
WARNING
Use a metal wire that can withstand a temperature of 400° F (200° C). The wire gauge must also support
the operational current (A) listed on the device spec sheet.
7. Replace the rear panel by screwing in the six (6) fixing screws and ensuring that the electrical connector
is firmly in place.
8. Make the electrical and grounding connections according to the electrical diagram. (Figure 4)
NOTE: See figures 6, 7, and 8 for details on the electrical connections.
9. Replace the grease drawer and the two (2) front panels in their original position by tightening the four (4) bolts.
WARNING
Be sure not to pinch the unit’s internal wiring of the unit when replacing the front panels.

3. OPERATION
WARNING
Never leave the thermostat knob(s) in the maximum position when the plate is not used.
This could cause the plate to overheat, turn black, and could cause damage
3.1. FIRST USE
Factory plate protection
1. Before using the unit, heat the plate to 300° F for five (5) minutes to burn off the protective coating.
2. Turn off the unit and allow it to cool down.
3. Wash the plate with soapy detergent or a mild cleaner to completely remove the residue.
4. Rinse with hot water and repeat the process a second time.
3.2. IGNITION
1. Turn the thermostat(s) to the “OFF” position.
2. Make sure the plate is well oiled.
3. Adjust the thermostat(s) to the desired position. A red light will turn on to indicate that the element
is heating his section of the plate. (Figure 5)
NOTE: Each thermostat has a indicator light; the number of elements and thermostats depends
on the griddle model.
NOTE: We recommend preheating the griddle. Adjust the thermostat(s) to the desired temperature
about 20 minutes before you start cooking.
3.3. PROLONGED SHUTDOWN
1. Turn the thermostat(s) to the “OFF” position.
2. Turn off the main electric supply.
NOTE: Be sure to condition the griddle before prolonged shutdown to prevent rusting and degradation
of your cooking surface.

4.MAINTENANCE
4.1. CONDITION
It is essential to coat the plate with oil immediately after use and to keep it oiled at all times to prevent rust.
NOTE: This step does not apply to griddles with a polished chrome finish.
After cleaning the griddle, follow these steps to ensure optimal long-term performance:
1. Heat the griddle to 300° F.
2. Apply a few ounces of frying oil.
3. Spread the oil with a soft cloth over the entire surface.
4. Wipe off excess oil.
4.2. CLEANING
Keep the griddle as clean as possible to prevent stains from charring the hot surfaces. Regular cleaning
of the griddle will ensure better cooking performance and a longer life for your unit.
NOTE: Cooking plates with a polished chrome (CP) finish are more energy efficient but require rigorous maintenance.
Refer to the specific maintenance instructions below to maintain optimum performance.
Every day, thoroughly clean exposed surfaces with a mild soap or other commercial cleaner designed for this purpose.
Remove, empty, and clean the grease drawer regularly.
•Polished steel plate
◽During use, regularly clean the plate with a scraper.
◽Each day, turn off the griddle, let it cool (to 300° F), pour room temperature water over the griddle,
and clean with a scraper.
◽Once a week, clean the griddle surface thoroughly using a Scotch Brite™ type abrasive or a scrub brush
as needed. Brush in the direction of the griddle steel grain while it is still warm. If detergent is used,
be sure to rinse well with clear water after cleaning.
◽After cleaning, seasoned the plate as specified in these instructions.
•Polished chrome finish (CP) plate
◽During use, regularly clean the plate with a chrome plate scraper. Never use an abrasive or a brick scraper
on the chrome finish.
◽Every day, clean the plate with a damp cloth and polish with a dry, soft cloth.
◽Once a week, use a non-abrasive, silicate-free cleaner such as Bon Ami® for charred or blackened areas.
Rinse off the cleaner thoroughly with clear water and then polish with a soft dry cloth.
