CHAPTER 1. PRODUCT IDENTIFICATION
Cleveland Range, Inc. assigns two product identification numbers to each
SteamCraft 10: a model number and a serial number. The model number
identifies the product characteristics. The serial number identifies the indi-
vidual unit.
MODEL NUMBER The operating section of this manual (Chapters 1 through 4) covers four
models of the Steam Craft 10 steamers:
•Gas fired atmospheric generator 24-CGA-10
•Gas fired pressure generator. 24-CGP-10
•Electric atmospheric generator. 24-CEA-10
•Electric pressure generator 24-CEP-10
The service section of this manual (Chapters 5 through 8) covers only the
atmospheric models:
•Gas fired atmospheric generator 24-CGA-10
•Electric atmospheric generator. 24-CEA-10
Each character of the model number identifies a characteristic of the
steamer. The Steam Craft 10 is 24 inches wide; a Convection steamer,
Electric or Gas powered, Atmospheric or Pressurized steam generator, and
has the capacity for 10 cooking pans.
This manual covers all standard features and options available on
SteamCraft 10 steamers. Other than selection of options, there are
presently no significant design, parts, or operating differences among
steamers with the same model number. Figure 1-2, Sheets 1 through 4
illustrate the four SteamCraft 10 models and identify the major components.
SERIAL NUMBER During manufacture, SteamCraft 10's are assigned individual serial num-
bers. A typical SteamCraft 10 serial number is: WC-7350-90G-02. The left
half of the number carries design information. The right half of the number
contains the manufacturing date and the unit of the manufacturing lot The
date of our sample number is 90G-02:90=1990, G=July. 02=the second unit
of the manufacturing lot Serial numbers arc used when explaining differ-
ences in design, parts, or operation among units with the same model
number. For example: a particular part may be used on SteamCraft 10's
with serial numbers before WC-7350-90G-02, and a different part used on
steamer WC-7350-90G-02 and those manufactured after it.
PRODUCT INFORMATION PLATE
The Product Information Plates list the unit's model and serial numbers, and
power and wiring requirements. These plates are located on the left side
panel, in the lower right corner. Figure 1-1illustrates typical SteamCraft 10

INSTALLATION DIAGRAM NOTES
1 . For each unit, the installer must provide a ground con-
nection and a separate fused disconnect switch.
2. The Product Identification Plate, located in the lower right
corner of the left side panel, specifies the electric power
and gas utility requirements.
3. A manual shut off valve and a drip leg must be installed
between the main gas supply and the steamer supply
lines-Bleed air from the gas line at the fitting closest to
the internal automatic gas valve. Refer to Figure 2-14 for
the recommended component arrangements.
4. Never exceed 14" water column (1/2psi) gas pressure. If
the gas supply pressure exceeds 14" water column, a
pressure regulating valve must be installed in the gas
supply plumbing to reduce the gas pressure to less than
14" water column.
5. The unit must have a cold water supply, NOT HOT. The
water supply must meet the quality requirements of
Table 2-2,and the pressure requirements on page 16.
6. A SteamerGard filtering system is recommended when
water quality does not meet the Table 2-2 requirements,
7. Run a single water line between the main cold water supply
and the tee. The two separate steam generator and
condenser/blowdown supply lines are relatively short.
8. A manual shut off valve must be installed between the main
water supply and the steamer supply lines-Refer to Figure
2-10 or2-11 for recommended component arrangements.
9. The drain line must have a gravity flow away from the
steamer, and must not be connected to the drain lines of any
other equipment.
10. The drain line must be free air vented. If the line empties
into a floor drain, there must be a one inch minimum
clearance between me drain line and the floor drain
openings-The floor drain must not be located under the
body of the unit.
11. To maintain proper operation and full warranty coverage,
the unit must be level from to back and side 10 side.

Page 10 Charter 2,SteamCraft 10 Service Manual Models 24-CGA-10, 24-CGP-10, 24-CEA-10, 24-CEP-10
PREPARATION FOR INSTALLATION
Select and prepare the SteamCraft 10 operating location before permanently
positioning the unit. Protect the unit and packaged components during site
preparation. Do not select the operating location or start installation before
checking the electric power, gas, and water quality requirements to assure
proper drainage, ventilation, and safety.
Protecting The SteamCraft 10 Do not remove the SteamCraft 10 from its shipping canon until just before
installation. If me shipping canon has already been removed and discarded,
refer to Unpacking and Inspection on page 18, and inspect me shipment.
Remove the SteamCraft 10 and components from the immediate work area
during storage, site preparation, and while running the utility supply lines to
the operating location. To protect the SteamCraft 10 from dirt, and prevent
loss or damage, take the following precautions as a minimum.
1. Leave packaged components inside the shipping canon or cooking com -
partment.
2. Keep the SteamCraft 10 dean by covering it with a plastic tarp or drop
cloth.
3. Do not store other items on top of the SteamCraft 10.
Electric Power Requirements The characteristics of me electric power supply must match the power
requirements specified on the SteamCraft 10 product identification plate.The
plate is located on the left side panel, in the lower right comer, as detailed in
Figure 2-2.
Gas Supply Requirements NEVER EXCEED 14" WATER COLUMN (1/2 psi) GAS PRESSURE. If the
gas supply pressure exceeds 14" water column, a pressure-regulating valve
must be installed in the gas supply plumbing to reduce the gas pressure to
less than 14" water column.
•Natural gas pressure must be between 4" -14" water column.
•L.P. gas supply pressure must be between 12" -14" water column.
Exhaust Hood Requirements
All Models In addition to the required venting of gas-fired equipment, some state and
local codes require me venting of steam generating equipment. It is the
responsibility of me owner and/or installer to learn and comply with these
codes.
•Models 24-CGA-10 and 24-CGP-10 have gas-fired steam generators with
an exhaust vent on top of the unit These units MUST be installed under an
exhaust hood suitable for ventilation and operation of gas-fired appliances,
as specified by local and national codes.
•Models 24-CEA-10 and 24-CEP-10 have electric steam generators and do
not have an exhaust vent. In some areas, local codes require installation of
these units under an exhaust hood suitable for ventilation and operation of
steam generating appliances.

Models 24-CGA-10, 24-CGP-10, 24-CEA-10, 24-CEP-10 SteamCraft 10 Service Manual, Chapter 2 Page 11
Water Quality Requirements
CAUTION
Using water not within the limits specified in this
manual could void or adversely affect Cleveland
Range's warranty coverage of the SteamCraft 10.
As with any steam generating equipment, poor water quality degrades
SteamCraft 10 performance. If feed water is low in Total Dissolved Solids
(TDS) and free of particulate matter, the steam generator, heating element,
and valves of me Steam Craft 10 will give years of trouble-free service
with a minimum of maintenance.
In some areas, even potable tap water contains a variety of impurities that
can cause costly problems in steam generating equipment. Of primary
concern are mineral salts and other impurities, which remain behind as
lime or scale deposits during the steam generating process. These deposits
have caused components to fail, including nearing elements, probes, and
solenoid valves. Of equal importance is me decrease in heat transfer
efficiency caused by lime and scale deposits. Decreased heat transfer
increases water and power consumption. Use of the SteamCraft 10 in areas
with poor water quality requires installation of a SteamerGard water
treatment system or increased frequency of maintenance, cleaning, and
descaling.
Check the quality of supply water as described below before starting con-
struction of the water supply lines. If a SteamerGard water treatment
system must be installed to achieve acceptable water quality, install it
before connecting the water supply lines to the SteamCraft 10. For more
information on water treatments, refer to Softened, Treated, or Filtered
Water on page 16.
Contact a local water treatment specialist for an on-the-premises water
analysis. The recommended minimum feed water quality requirements for
the SteamCraft 10 are listed in Table 2-2.
