GAS COUNTERTOP CHARBROILERS

GENERAL

Vulcan/Wolf Gas Countertop Charbroilers are designed for commercial use only and feature fast, efficient gas heat. Each burner is controlled by an adjustable gas valve. Cast radiants are located directly above each burner to maintain uniform temperature. Radiants are easily removed for cleaning when cool.

Heavy-duty cast iron top grates are reversible to allow all or part of the cooking grid surface to be level or sloped. A crumb tray is provided to collect fat run-off and debris; it opens to the front for inspection or cleaning.

INSTALLATION

UNPACKING

This charbroiler was inspected before leaving the factory. The carrier assumes full responsibility for the safe delivery upon acceptance of the shipment. Check for possible shipping damage immediately after receipt.

If the charbroiler is found to be damaged, complete the following steps:

1. Carrier must be notified within 5 business days of receipt.

2. Carrier’s local terminal must be notified immediately upon discovery (note time, date, and who was spoken to), and follow up and confirm with written or electronic communication.

Before installing, verify that the type of gas (natural or propane) and the clearance dimensions agree with the specifications on the rating plate which is located on the lower front corner on the right side.

LOCATION

The installation location must be kept free and clear of combustibles. Do not obstruct the flow of combustion and ventilation air. DO NOT install the charbroiler adjacent to fryers unless following the provisions detailed by local codes and/or the applicable sections of ANSI-Z223.1/NFPA #54 (latest edition) and NFPA #96 (latest edition) in the United States of America or CAN/CSA 149.1 (latest edition) and CAN/CSA149.2 (latest edition) in Canada.

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 obstruct the air flow into and around the appliance. Do not obstruct the flow of flue gases through and above the broiler's top grate. Position the broiler in its final location. Check that there are sufficient clearances to service the broiler and to make the required gas supply connection(s). Provide 24" clearance at the front for cleaning, maintenance, service and proper operation.

This broiler is for use in non-combustible locations only. Installation in combustible locations is prohibited unless following the provisions detailed by local codes and/or the applicable sections of ANSI-Z223.1/NFPA #54 (latest edition) and NFPA #96 (latest edition) in the United States of America or CAN/CSA 149.1 (latest edition) and CAN/CSA149.2 (latest edition) in Canada and approved by the authority having jurisdiction.

and its parts are hot. Use care when operating, cleaning or servicing the charbroiler.

Grate – The grates can be utilized flat or sloped for operational flexibility.

Deflector Tray – The deflector tray is the removable pan with holes in it. The deflector tray deflects heat back toward the cooking surface while allowing debris to pass through the holes and into the crumb tray below. The deflector tray should always be in place above the crumb tray when operating.

Never cover the deflector tray holes with foil or allow the deflector tray holes to become blocked with debris. This will cause a buildup of heat that can potentially damage and warp components of the charbroiler.

Crumb tray – The crumb tray is the removable pan without holes in it. The crumb tray catches any debris that passes thru the deflector tray and should always be installed beneath the deflector tray. (Fig. 1).

Supercharger Burner Divider These act as dividers between cooking zones to offer flexibility in cooking and help direct heat upwards to provide for a even heating pattern. You may remove some or all of the supercharger burner dividers at your discretion if you find your production method works better without them. The super charger burner dividers are installed by inserting the hooks thru corresponding slots at the front (Fig. 2) and the back rests in the super charger guide to the rear. (Fig. 3).

- 5 -

Radiant – The charbroiler must never be operated without the radiants in place. They protect the burner from food drippings and heat up to provide an even heating pattern. The radiants are installed by inserting the tab thru the corresponding slot in the heat shield to the front (Fig. 4-A) and the back of the radiants set on the radiant rest to the rear (Fig. 5-A).

Burner – The burner shutter should engage the orifice to the front (Fig. 6) and rest in the burner slot to the rear of the unit.

Proper burner shutter adjustment is important for optimal charbroiler performance. The burner shutters should only be adjusted with all radiants in place. The shutter will typically be about 50% open for natural gas and 80 to 100% open for LP. A properly adjusted burner should exhibit solid blue flames that are touching the burner. All traces of yellow should be adjusted out of the burner flame for natural gas and only a slight yellow tipping should be observed on LP gas. Large, yellow tipped flames typically indicate not enough air and the burner shutters should be opened slightly. Floating flames (not touching the burner) typically indicate too much air and the shutter should be closed slightly.

LEVELING

It is important that the charbroiler is level front to back and left to right. Areas of uneven heat distribution will occur on an unlevel unit. The charbroiler is equipped with adjustable legs. Turn the feet at the bottom of the legs to adjust to level. The unit should be rechecked for level anytime it has been moved.

VENTILATION HOOD

The broiler must be installed under a suitable ventilation hood. For safe operation and proper ventilation, keep the space between the charbroiler and vent hood free from any obstructions.

GAS CONNECTION

The data plate on the lower right side of the charbroiler indicates the type of gas your unit is equipped to burn. DO NOT connect to any other gas type.

All gas supply connections and any joint compound must be

resistant to the action of propane gases.

Purge the supply line to clean out any dust, dirt, or any foreign matter before connecting the line to the unit.

Codes require that a gas shut-off valve be installed in the gas line ahead of the

charbroiler. The gas supply line must be at least the equivalent of ¾” iron pipe.

60” a n d 7 2 ” m o del s h a v e a g as inlet at each end of the unit. The unit will arrive from the

factory with a metal cap on one end and a plastic dust cover on the other. You may move the metal cap to the other end and use which ever connection point is most convenient to the available supply outlet. The plastic dust cover must be replaced with a metal pipe cap if you do not use that location as the gas inlet. Do not connect both of the available charbroiler gas inlets to the gas supply.

A pressure regulator is supplied and must be installed outside of the broiler when making the gas supply connection. Standard orifices are set for 5"WC (Water Column) for Natural Gas — 10"WC (Water Column) for Propane. Use the 1/

” pipe tap on the bur n er

manifold for checking pressure. Make sure the gas piping is clean and free of obstructions, dirt, and piping compound.

An adequate gas supply is necessary. Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance. A minimum supply pressure of 7" W.C. for natural gas and 11" W.C. for propane gas is recommended. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable drop.

When testing the gas supply piping system, if test pressures exceed ½ psig (3.45 kPa), the charbroiler and its individual shutoff valve must be disconnected from the gas supply piping system. When test pressures are ½ psig (3.45 kPa) or less, the charbroiler must

6.16 and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for use With Gas Fuel, ANSI-Z21.41 • CSA 6. 9. In addition, adequate means must be provided to limit movement of the broiler without depending on the connector and the quick-disconnect device or its associated piping to limit broiler movement. Attach the restraining device at the rear of the charbroiler. If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect the restraint prior to turning the gas supply on and return the charbroiler to its installation position.

valve during any pressure testing of the system.

Prior to lighting, check all joints in the gas supply line for leaks.

Use soap and water solution. Do not use an open flame.

GAS PRESSURE REGULATOR INSTALLATION

Gas regulator pressure is preset at 5” W ater Column (W . C . ) for natural g as, and 10” W .C. for propane gas. Minor adjustments may be required based on site specific gas pressure.

Install the regulator as close to the broiler on the gas supply line as possible. Make sure that the arrow on the underside of the regulator is oriented in the direction of gas flow to the broiler (Fig. 7) and the regulator is positioned with the vent plug and adjustment screw upright (Fig. 8).

The supply pressure (upstream of the regulator) should be 7-9 ” W .C. for natural gas and 11-12” W .C. for propane gas. At no time should the charbroiler be connected to supply pressure greater than ½ psig (3.45 kPa) or 14” W. C.

CASTER EQUIPPED CHARBROILERS

Charbroilers mounted on stands with casters must use a flexible connector (not supplied) that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 • CSA 6.16 and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for use With Gas Fuel, ANSI-Z21.41 • CSA 6.9. In addition, adequate means must be provided to limit movement of the broiler without depending on the connector and the quick-disconnect device or its associated piping to limit broiler movement. Attach the restraining device at the rear of the charbroiler. If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect the restraint prior to turning the gas supply on and return the charbroiler to its installation position.

Pilot Control Valves – The pilot control valves are located between the burner control knobs and accessed thru slots in the front panel (Fig. 10). There is one pilot and corresponding adjustment screw for every burner.

Using a flathead screwdriver, turn the slotted, hex-head pilot adjustment screw clockwise to decrease the flame and counter clockwise to increase the flame. Standing pilots should be adjusted to provide a slight yellow tip on the flame.

Burner Control Valves – There is one valve for each burner. To initially light the burners, the knobs should be turne d to t h e “MAX ” setting then adjusted to the desire setting as needed.

The burners will be off when the control knob is turned all the way to

the right and pointin g to “OF F ” . T h e

burners will be at maximum setting when turned all the way to the left

and poi nting to “ MAX”. A m edium

burner setting can be achieved by adjusting the knob approximately half

way be t w een th e “O F F ” and “MAX”

marks. See Fig. 11. The charbroiler is a free vented

appliance. All products of combustion and the heat generated by the burners passes through the grates. When food products are placed on the grates, this blocks the venting and causes a temperature build-up. OFF MEDIUM MAXIMUM
