OPERATING INSTRUCTIONS
There are two separate heating zones on the Roller Grill (front zone and rear zone). Temperature
for each zone is controlled independently. After startup, one zone can be used to hold product at
serving temperature, while the other zone is used to bring additional product up to serving
temperature.
Helpful Tip: Use front zone to hold product at serving temperature, to avoid having to
reach over the higher heat zone for product which is ready to serve.
