Installation, Operation and Care of

GDC SERIES GAS DUPLEX COOKERS

KEEP THESE INSTRUCTIONS FOR FUTURE USE

GENERAL

The GDC Series Gas Duplex Cookers combine a high efficiency gas griddle with adjustable-height,
thermostat-controlled electric platens to provide fast production of grilled foods. Vulcan Duplex
Cookers are produced with quality workmanship and material. Proper installation, usage and
maintenance will result in many years of satisfactory performance.

It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions
provided.

INSTALLATION

Before installing, verify that the type of gas (natural or propane), the elevation, and the electrical service
agree with the specifications on the rating plate, located on the left side panel.

UNPACKING

This cooker was carefully inspected before leaving the factory. The transportation company assumes
full responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking,
check for possible shipping damage. If the cooker is found to be damaged, save the packaging material
and contact the carrier within 15 days of delivery.

CAUTION: Lower all platens before attempting to move this cooker.

LOCATION

The installation location must be kept free and clear of combustibles. Clearances from combustible
and non-combustible construction must be a minimum of 7 inches from the sides and 2 inches from
the back. A minimum front clearance of 32 inches is required for service and operation.

Sufficient air should be allowed to enter the room to compensate for the amount of air removed by any
ventilating system and for combustion of the gas burners. Do not permit fans to blow directly on the
cooker. Avoid open windows at the sides or back. Avoid wall-type fans which create air cross currents
within the room. Do not obstruct the air flow into and around the cooker. Do not obstruct the flow of
flue gases from the flue duct (when so equipped). It is recommended that the flue gases be ventilated
to the outside of the building through a suitable and properly installed ventilation system.

ASSEMBLY

Legs

The duplex cooker is shipped as a complete unit and does not require field assembly except the
supporting legs or stand. Screw the legs on the four corners of the cooker, into the welded nuts. Hand
tighten the legs and set in place.

Casters (Optional)

If the cooker is equipped with casters, the gas connector (available from Vulcan-Hart) must comply with
the Standard for Connectors of Movable Gas Appliances, ANSI-Z21.69 (latest edition), and a quick­disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas
Fuel, ANSI-Z21.41 (latest edition).

When casters are installed, provide a restraining device for the gas line to limit movement of the cooker
without depending on the connector and/or any quick-disconnect device or its associated piping to limit
cooker movement. Attach the restraining device to a rear leg of the stand.

If it is necessary to disconnect the restraint, turn off the gas supply before disconnection. Reconnect
the restraint before turning the gas supply on and returning the cooker to its installation position.

Instructions for installing casters to the cooker are included with the casters.

Stand (Fig. 1)

1. Thread leg extension into fixed nut in griddle frame.

2. Thread adjustable leg through undershelf into leg extension.

3. Tighten both leg extension and adjustable legs.

4. If casters are furnished instead of adjustable legs, the locking swivel casters must be placed in the
front.

5. To level the griddle plate, turn the adjustment screw at the bottom of each leg.

GAS CONNECTIONS

Make the gas connection to the appropriate location on the cooker according to applicable codes.
Make sure the pipes are clean and free of obstructions, dirt, and piping compound.

CAUTION: All gas supply connections and any pipe joint compound must be a type that is
resistant to the action of liquified petroleum gases.

Codes require that a gas shutoff valve be installed in the gas line ahead of the duplex cooker.

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, fully purge gas pipes to remove air.

TESTING THE GAS SUPPLY PIPING SYSTEM

When test pressures exceed

/2 psig (3.45 kPa), the cooker and its individual shutoff valve must be

disconnected from the gas supply piping system.
