Installation, Operation and Care of VL2 & VL3 GAS FOOD STEAMERS

SAVE THESE INSTRUCTIONS FOR FUTURE USE

GENERAL

Vulcan-Hart suggests that you thoroughly read this entire manual and carefully follow all of the instructions provided. Your Vulcan Model VL Food Steamer is produced with quality workmanship and materials. Its boiler is fully automatic with the heat input controlled by preset pressure switches. A solenoid valve feeds makeup water as needed. The steamer is equipped with adjustable feet.

Proper installation, usage and maintenance of your food steamer will result in many years of satisfactory performance.

INSTALLATION

Before installing, verify that the electrical service and gas supply (natural or propane) agrees with the specifications on the rating plate located on the boiler access door. If the supply and equipment requirements do not agree, do not proceed with the installation. Contact your dealer or Vulcan-Hart immediately.

UNPACKING

This food steamer was inspected before leaving the factory. The transportation company assumes full responsibility for safe delivery upon acceptance of the shipment.

IMPORTANT: Immediately after unpacking, check for possible shipping damage. If the food steamer is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

REMOVE THE BURNER SHIPPING RESTRAINT

The steamer is shipped as a complete unit and no assembly is required. However, the burner shipping restraint must be removed (Fig. 1). To do this, remove two hex nuts and two washers from the weldstuds on the boiler shell.

LOCATION

Position the food steamer in its final location. Check that there are sufficient clearances to service the controls, for door swings, etc., so there will be no problem in making the required supply and drain connections. Recommended clearances for proper operation is 36" ( minimum clearance from combustible or noncombustible construction is 6" ( back. The recommended clearances for servicing the steamer are 18" ( and 36" ( during servicing at customer's expence.

91.4 cm) in the front. Clearances less than 18" may require removal of adjacent equipment

INSTALLATION CODES AND STANDARDS

In the United States, the Vulcan steamer must be installed in accordance with state and local codes, with the National Fuel Gas Code, (ANSI-Z223.1, latest edition) available from the American Gas Association, 1515 Wilson Boulevard, Arlington, VA 22209, with the National Electrical Code (ANSI/ NFPA No. 70, latest edition) available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269 and with

Vapor Removal from Cooking Equipment,

(NFPA-96, latest edition)

available from NFPA.

In Canada, the steamer must be installed in accordance with local codes, with the National Fuel Gas Code (CAN/CGA-B149.1 latest edition) available from the Canadian Gas Association, 178 Rexdale Boulevard, Etobicoke, Ontario, Canada M9W 1R3, and with the Canadian Electrical Code (CSA C22.2 No.3, latest edition) available from the Canadian Standards Association, 178 Rexdale Boulevard, Etobicoke, Ontario, Canada M9W 1R3.

REQUIREMENTS FOR GAS APPLIANCES

Keep the food steamer free and clear from all combustible substances. Do not obstruct combustion and ventilation openings on the steamer.

Do not obstruct the air flow into and around the food steamer. This air flow is necessary for proper combustion of gases and for ventilation of the food steamer. Provisions for ventilation and for incoming air supply for the equipment in the room must be in accordance with the National Fuel Gas Code, ANSI Z223.1 (latest edition).

Do not obstruct the flow of flue gases from the flue duct located on the rear of the food steamer. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

For steamers equipped with casters, the installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 (latest edition), and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41 (latest edition). Provide a gas line strain relief to limit the movement of the steamer without depending on the connector and any quick-disconnect device or its associated piping to limit the steamer movement. Attach the strain relief to the rear of the steamer (Fig. 2).

If disconnection of the gas line strain relief is necessary, turn off gas supply before disconnection. Reconnect this strain relief before turning the gas supply on and returning the steamer to its originally installed

LEVELING AND ANCHORING

Place a level on the horizontal parts of the steamer. Adjust the feet at the base of the steamer to level the steamer in both the left-to-right and front-to-rear directions. After leveling, raise up the steamer on

the right side about adjustable flanged feet 1 to 1

/16" to 1/8" (0.16 to 0.32cm) to drain the cooking compartments by rotating the

/2 turns clockwise. Check by pouring a little water in the compartment;

all the water should drain.

The feet have holes in the flanges for anchor bolts.
