24CGA10.2

Overview

The Cleveland 24CGA10.2 SteamCraft Gemini is a floor-model, pressureless convection steamer with two independent cooking compartments. Each compartment holds five 12-inch by 20-inch by 2½-inch full-size pans, for a total capacity of ten pans. Each compartment has its own gas-powered steam generator, controls and valves, allowing the compartments to be operated separately.

The generators produce steam for cooking, and brass steam jets distribute it through the compartments. The generator cleaning ports are on the exterior of the unit. In standby mode, the generators remain at steaming temperature so the steamer is ready to cook quickly. The manual bypass switch provides continuous steam. Opening a compartment door shuts off its steam supply.

Installation & Requirements

Location, clearance and ventilation

The manual states that the Gemini must be level from front to back and side to side before operation. It gives an operating weight of 650 pounds and says the selected location must be able to support the appliance. A suitable drain must be available within 12 feet. Do not install the steamer directly over a drain: steam from the drain can affect operation and cooling-air circulation and may damage electrical components.

Maintain at least 3 inches of operating clearance at both sides and at the back. The manual recommends 12 inches on the right side for service access and approximately 24 inches in front for opening the door and handling pans. The appliance must be installed under a suitable exhaust hood. Proper ventilation air is required for safe, efficient operation; keep the appliance area clear of combustibles and do not block its air vents. The manual says all stated clearance requirements apply in combustible and non-combustible locations.

Drain connection

The drain must have gravity flow from the steamer to the floor drain; do not install a trap. It must be free-air vented, with at least 1 inch between the drain-line end and the top of the floor drain. Do not connect the steamer drain directly to another appliance’s drain or plumbing, or directly to a floor drain or sewer line. The manual also prohibits PVC or any drain material that cannot withstand 180°F. For an extension of 6 feet or less with no more than two elbows, it permits 1½-inch inside-diameter pipe and fittings. For an extension of 6 to 12 feet, or one requiring three or more elbows, it specifies 2-inch inside-diameter pipe and fittings.

Gas and electrical supply

Check the rating plate and ensure the gas supply matches the specified gas type. The manual states that gas pressure must not exceed 14 inches water column; its acceptable ranges are 4½ to 14 inches water column for natural gas and 11 to 14 inches water column for propane. It calls for a manual shutoff valve between the supply and steamer and recommends a sediment trap in the gas line. The manual identifies a ¾-inch gas inlet and directs installers to follow applicable local codes or the referenced gas installation codes.

The electrical supply must match the rating plate. The manual requires grounding and installation in accordance with applicable local electrical codes; it says the unit is not suitable for connection to a GFCI. It also calls for a main disconnect switch and a separate fuse or breaker near the unit. The product listing gives the electrical supply as 120 V, 60 Hz, single phase, 300 W.

Operation

When a compartment is turned on, it automatically fills its steam generator with water. The manual describes this as a way to prepare the steamer at the start of a shift without starting steam generation. The standby mode holds the generators at steaming temperature for quick cooking. Use the manual bypass switch when constant steam is required. The product information describes a timer for unattended task management; the supplied descriptions differ on whether the timer is a 60-minute electromechanical timer or a 90-minute EasyTimer, so verify the configuration for the specific unit.

Opening a door shuts off the steam supply to that compartment. The manual warns that the steamer and its parts remain hot while the main external power switch or ON/OFF switch is on, and remain hot for some time after the ON/OFF switch is turned off. To reduce burn and scald risk when opening a door, stand to the hinge side and back from the door, open it slowly, and wait for steam and heat to dissipate before reaching inside. If a door is stuck shut, do not force it open; the manual warns that a blocked drain may leave hot water in the compartment.

Cleaning & Maintenance

Daily care

The manual calls for blowing down each steam generator daily according to the generator blowdown instructions in its operating chapter. It also calls for cleaning the interior and exterior of the steamer according to the shutdown instructions. The specific blowdown and shutdown steps are not included in the supplied manual excerpts; use the applicable instructions in the complete manual.

Drain cleaning

Inspect the cooking compartment before every steaming operation and remove food scraps or debris from the racks, walls and floor, paying particular attention to the drain and drain screen. Do not use the steamer if water is standing in the drain opening. Remove anything blocking the drain or screen, and make sure the screen is in place over the drain.

Weekly, inspect the drain screen and drain line for blockage. The manual says to rotate the screen 90 degrees to inspect the drain opening, clean the opening and return the screen to its operating position. Clean the drain weekly with a USDA-approved drain cleaner, following that cleaner’s manufacturer instructions, then flush the drain with clean water. Never operate the steamer without its drain screens in place.

Descaling

The manual says to descale the steam generators at least once a month, depending on scale buildup. If scale buildup is serious, it recommends installing a water treatment system for the steamer or increasing the descaling frequency if water treatment is not possible. Cleveland Range recommends DISSOLVE descaler, part number 106174, or part number 1061741. The manual says no other system of steamer descaling should be used and specifies that its descaling instructions are for those DISSOLVE products only. The supplied excerpts do not include the step-by-step descaling procedure, so follow the complete manual’s procedure for the 24CGA10.2 rather than improvising.

Troubleshooting

A blocked or slow drain or drain screen is a key issue identified in the manual. Possible signs or consequences include standing water in the cooking compartment, hot water spilling when the door opens, steam leaking around the door gasket, pressure fluctuations or compartment implosion, and reduced convection and cooking performance. Inspect and clean the drain and screen as described above; do not operate the unit when water is standing in the drain opening.

If the door is stuck shut, do not force it open. The manual says a stuck door may indicate a blocked drain and that hot water may fill the compartment and spill out if the door is forced. The manual also states that the steamer must be level front to back and side to side; if it is suspected to be out of level, shut it down and call a qualified Cleveland Range authorized service agency. For service, the supplied parts manual lists Cleveland service/parts at 1-844-724-2273 and directs callers in Canada to select the Canada service option.

Applications

The two independently controlled compartments allow a commercial kitchen to steam separate products or batches at the same time, with up to five full-size pans in each compartment. The ten-pan capacity can support batch cooking in restaurant, institutional and other foodservice kitchens. Operators can use the unit for foods suited to steam cooking, such as vegetables, seafood, poultry or prepared sides, while selecting separate cooking runs for each compartment.
