DESCRIPTION

The Nieco Model 820 and 1020 Cheese Melter is a compact, self contained, flow through unit that is designed to melt cheese and to toast buns. The unit employs dual 12" wide rod belts, or a single 24” wide belt that flow through the cheese melter in opposite directions between the three upper and one lower burner or four upper and two lower burners in the Model 1020. Each belt is independently driven and controlled.

INSTALLATION

PRE-INSTALLATION

Uncrate the machine, and inspect for shipping damage. Contact the factory if there is obvious damage. Remove the tape securing the machine parts, and install the parts in their proper location. Refer to the Parts and Location section of this manual. If you find concealed damage to any part of this unit, contact your freight carrier immediately. The factory warranty does not cover freight damage.

MOUNTING

If the cheese melter was shipped with a tubular stand, refer to separate tubular stand assembly instructions.

HOOD REQUIREMENTS

This appliance must be installed under a ventilation hood of adequate size and capacity (approximately 600 CFM). The hood should be at least 6" larger in all dimensions than the appliance top, and be 12" to 18" above the top. Do not obstruct the flow of combustion and ventilation air. An adequate air supply must be available for safe and proper operation.

Note: See the National Fire Prevention Association booklet on ventilation of cooking equipment. Write to: NFPA, 470 Atlantic Ave., Boston, MA 02210. Local codes on venting must also be complied with.

CLEARANCE

For proper installation, the minimum clearance from combustible and non-combustible construction is 6" from the back and 6" from the front of the machine. Keep appliance area free from combustibles.

To facilitate disassembly and service of the unit a minimum of 24" should be allowed on the control panel (right) side of the cheese melter, as well as on the feed and discharge ends of the cheese melter.

GAS CONNECTION

At rated BTU capacity, the gas supply should deliver a pressure of at least 6" water column at the cheese melter connection for natural gas, and 11" water column for propane gas. Incoming gas supply pressure must not exceed 14" water column for either type of gas.

This appliance was shipped from the factory ready for gas supply hook-up to the shutoff valve under the cheese melter. For disconnect, a manual valve must be located in the gas supply line upstream from the connecter.

If the machine is installed on a moveable stand; (1) the installation shall be made with a connector that complies with the Standard for Connectors for Moveable Gas Appliances, ANSI Z21.69-1987, and Addenda, Z21.6a-1989, and a quick disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41-1989, and (2) adequate means must be provided to limit the movement of the appliance without depending on the connector and the quick-disconnect device or its associated piping to limit the appliance movement. (See figures on page 6.)

Note: Appliance installation must conform with all local codes, or in the absence of local codes, with the National Fuel Gas Code ANSI Z223.1-1988. Check all fittings for gas leaks, including pilot tubing and inlet connections as soon as the appliance is connected to the gas supply.

Note: This appliance and its individual shutoff valve must be disconnected from the gas supply piping systems during any pressure testing of that system in excess of 1/2 psig (3.45 kPa).

Note: This appliance must be isolated from the gas supply piping system by closing its individual manual shutoff during any pressure testing of that system at test pressures equal to or less than 1/2 psig (3.45) kPa).

In Canada, installation shall be in accordance with CAN/CGA-B149.1 Natural Gas or CAN/CGA-B149.2 Propane Gas, and local codes where applicable.

By public initiative, the State of California has adopted legislation (Proposition 65) which requires manufacturers of many types of products, including gas appliances, to warn consumers of their products that contain chemicals or produce substances listed by the State of California to either cause cancer, birth defects, or other reproductive harm.

WARNING: If not installed, operated, and maintained in accordance with the manufacturer's instructions, this product could expose you to substances in fuel, or from fuel combustion which can cause cancer, birth defects, or other reproductive harm.

ELECTRICAL CONNECTION

Power requirements are stated on the unit nameplate and must be connected accordingly. Before starting cheese melter, tighten all electrical connections in control box.

Note: This appliance must be electrically grounded in accordance with local codes or in the absence of local codes, the National Electrical Code, ANSI/NFPA No. 70-1990. In Canada, in accordance with the Canadian Electrical Code CSA

22.1 part 1, or local codes.

WARNING: This appliance should be connected with a three-pronged grounding plug for your protection against shock hazard. Be sure to plug directly into a properly grounded three-prong receptacle. Do not cut or remove grounding prong from plug.

Note:

This appliance cannot be safely operated in the event of a power failure. No attempt should be made to operate during a power failure. Disconnect power supply before servicing.

PRE-OPERATION CHECK

Be sure that all parts are installed in the proper location. Refer to OPERATION section for lighting procedure. Start cheese melter and test for proper operation.

INSTALLING GAS APPLIANCE CONNECTORS AND FLEXIBLE GAS LINES CORRECTLY

RESTRAINING DEVICE INSTALLATION AND USE

This high strength restrainer is to be used with all moveable (castered) appliances. It must fully comply with International Approval Services requirements. References: Z21.69, Z83.11, and Z21.41 with current revisions. Installation is quick and positive. In Canada, device is in accordance with CAN 1-6.9-M70 Quick Disconnect Devices for use with gas fuel, and CAN 1-6.10-88 metal connectors for gas appliances.

Correct length for any appliance is simply a matter of loosening two adjuster clips (1) and re-tightening. (3" to 6" shorter than appliance connector is desired length.)

Restrainer is made of heavy duty steel cable, with a strong scissor hood (2) at one end, and an equally strong spring hook (3) at the other. Cotter pin (4) is supplied to secure the installation.

For safety in the kitchen area, and to insure maximum service life, it is vitally important to correctly install connectors.

In order to avoid sharp kinks or excessive bends that could have a damaging effect on the connector, it may be necessary to attach pipe elbows in order to bring the connector into its proper plane. For easy movement of the appliance, the connector should be installed with a "lazy" loop for minimum tension.

Note: Gas appliances should be disconnected prior to maximum movement. (Minimal movement is possible to connect hose.)

WRONG

Avoid sharp bends and kinks when pulling equipment away from wall.

RIGHT

Minimum pull of equipment is permissible for accessibility to quick disconnect devic

IMPORTANT: This Reastraining Device should be odered with every connector for Moveable appliances

OPERATION

In the following section, a brief step-by-step sequence of lighting and operating procedure is given. For reference, a condensed lighting procedure is located on the front of the control panel.

Step-By-Step Lighting Procedure

1. Turn on Main Power Switch.

2. Turn on Motor Power Switches.

3. Set Motor Speed Controls to desired cook time.

Note: Your cheesemelter is equipped with a constant burning pilot. After the initial lighting, the cheesemelter is shut down and re-lit simply by turning the main power siwtch on and off.

1. Main Gas Valve controls the flow of

incoming gas. Valve is open when handle is in-line with the piping, and closed when it is perpendicular.

2. Solenoid Valve automatically shuts off gas supply if power fails.

3. Pushbutton Gas Valves (2) control the flow of gas to the upper and lower burners. 3a is for the lower burner, and 3b is for the upper burners.

1 2 3a 3b

4. Open Main Gas Valve located on the lower left side of the machine. Valve is open when the handle is in-line with the valve.

5. Light the Lower Pilot Burner by holding in the red button marked bottom pilot and simultaneously pressing the red Pilot Ignition button. After pilot ignites, continue to hold the bottom pilot button in for about 20 seconds to insure pilot remains lit.

6. Repeat step 5 with the Upper Pilot Burner. After 20 seconds release pilot button and the main burners will ignite.

If the pilot lights are burning:

1. Turn on the exhaust hood above the cheesemelter.

2. Turn on the Main Power Switch. At this time, the main burners should ignite.

3. Turn on the Motor Switches, and set the cook times with the Motor Speed Control Knobs.
