CHAPTER 1 PRODUCT IDENTIFICATION
Cleveland Range, Inc. assigns two product identification numbers to each steamer: a model number and a
serial number. The model number identifies the product characteristics. The serial number identifies the
individual unit.
A. MODEL NUMBER
This manual covers the Gemini Model No. 24CGA6.2 and 24CGA10.2 Dual Steam Generator and
Convection Steamer.
Each character of this model number identifies a characteristic of the steamer. The Gemini Model No.
24CGA10.2 is 24 inches wide, a Convection steamer, Gas powered, and an Atmospheric steam generator
with a capacity for 10 cooking pans, this model has the extra suffix “.2” to differentiate it from our standard
10 pan model that does not have two separate generators. This manual covers all standard features and
options available on Gemini gas steamers.
Other than selection of options, there are presently no significant design, parts, or operating differences
among steamers with this model number. Figures 1-2 and 1-3 illustrate the two Gemini designs of gas fired
steamers and identifies their major components.
B. SERIAL NUMBER
During manufacture, Gemini Steamers are assigned individual serial numbers. Whenever any inquiry is
made with Cleveland Range regarding a steamer the serial number should be referenced.
C. PRODUCT INFORMATION PLATE
The Product Information Plate on the left side of the unit lists the model and serial number of the steamer.
Refer to Figures 1-2 and 1-3 for the location of the plate. Figure 1-1 illustrates a typical Gemini Product
