GENERAL
INTRODUCTION
This Service Manual covers specific service
information related to the models listed on the front
cover. Procedures in this manual will apply to all RRG
Heavy Duty Gas Griddles unless otherwise specified.
Raising of the griddle plate is not required for servicing
the griddle components. Griddle components are
serviced through the front and rear. Pictures and
illustrations can be of any model unless the picture or
illustration needs to be model specific.
The RRG, Rapid Recovery Griddle, plate is a
composite material which is engineered to provide a
high heat transfer rate to the food. The top surface can
be scored or dented by careless use of a spatula or
scraper. The center of the of the plate is an aluminum
core with sheets of stainless steel laminated to the top
and bottom exterior surfaces.
INSTALLATION
Generally, installations are made by the dealer or
contracted by the dealer or owner. Detailed
installation instructions are included in F-36981
Installation & Operation Manual that is sent with each
unit.
It should be noted that an improperly installed unit,
especially an unlevel unit can lead to premature
electrical component failures. A unit that is higher in
the front will cause the flue gases to vent improperly
and gather in the front near the electrical components.
All RRG models must be installed with an externally
mounted regulator.
The models, number of burners and BTU/HR input
rating are listed under GENERAL in the Installation &
Operation Manual.
OPERATION
Detailed operation instructions are included in the
Installation & Operation Manual sent with each unit.
The manual is also available online at
