Preparing the Site – General Information

Assure Sufficient Clearances

Clearances specified for the oven on the rating label are required for the proper cooling, ventilation, and combustion air supply. Make sure nothing obstructs the flow of combustion and ventilation air. Depending on the number of units being installed, make sure there is enough clearance between each unit, and from walls to the sides and to the rear. Failure to provide the necessary clearance may void the manufacturer’s warranty. A proper air supply for combustion and ventilation is critical to safe, efficient operation of the oven.

Equipment Leveling

For proper operation and water pan drainage, the equipment must be level. Use the leveling spacers provided with the casters. Install leveling spacers so that equipment is level when rolled into its final location.

Restraining Cables

Restraining cables must be installed to limit the movement of the appliance and protect flexible gas

lines from breakage on gas appliances with

casters. Anchor the cables into wall studs and connect them to the eyelets provided in the stand or warming cabinet. The installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors for Moveable Gas Appliances, CAN/CGA-6.16, and a quick- disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41, or Quick Disconnect Devices for Use with Gas Fuel, CAN1-6.9.

Provide a Powered Exhaust Hood

Code requires an exhaust hood. The hood must meet dimension requirements, and must have adequate exhaust capacity, based on the

combined BTU output of the ovens. Never make a direct connection to the oven exhaust vent.

Fire Safety

Do not store or leave combustible materials near the oven. Consult your local codes for fire protection requirements. Gas Leak Instructions must be posted. Your gas utility can supply a sign or the appropriate wording for a sign.

Gas Pressure

Test the building’s gas supply pressure. It must meet Cleveland Range’s specifications. (See pages 5-8.) If gas pressure is too high, install a pressure regulator (excess pressure will damage the equipment) – if too low, notify the gas company to raise pressure to specs.

Gas Flow

Sufficient gas flow is important to oven performance. During peaks hours of operation gas flow may be insufficient if pipe diameter is too small. Feed a multiple-oven installation with a manifold-type gas supply line sized properly for good flow.

Gas Plumbing

Provide a shut-off valve, drip leg, and flexible supply line for each oven. Use appropriate ¾-inch IPS plumbing components. Follow applicable codes. Seal all threaded joints with suitable joint compound, resistant to the action of liquefied petroleum gases.

Gas Leak Tests

After completing the gas plumbing, close all oven shut-off valves and test all upstream joints under pressure, using a soap-rich water solution. Repair

all leaks and retest. The steamer must be isolated from the gas supply system during any pressure testing as follows: (1) The appliance and its main manual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 14” water column (1/2 psi or 3.45 kPa). (2) The appliance must be isolated from the gas supply piping system by closing its main manual shut-off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 14” water column (1/2 psi or 3.45 kPA).

Electrical Supply: Oven

Each oven is equipped with a 120V/15A-power cord, with a three-prong (grounding) plug for protection against shock hazard. It should be plugged directly into a properly grounded three- prong receptacle. Do not cut off or remove the grounding prong from the plug. (Some local codes may require a different form of disconnect.)

Electrical Supply: Optional Warmer

The CR-334 warming cabinet can draw up to 30 amps, and must be provided with a suitable grounded branch circuit and outlet. The power
