IMPORTANT FOR YOUR SAFETY THIS MANUAL HAS BEEN PREPARED FOR PERSONNEL QUALIFIED TO INSTALL GAS EQUIPMENT, WHO SHOULD PERFORM THE INITIAL FIELD START-UP AND ADJUSTMENTS OF THE EQUIPMENT COVERED BY THIS MANUAL. POST IN A PROMINENT LOCATION THE INSTRUCTIONS TO BE FOLLOWED IN THE EVENT THE SMELL OF GAS IS DETECTED. THIS INFORMATION CAN BE OBTAINED FROM THE LOCAL GAS SUPPLIER.
Installation, Operation and Care of HGB(M) and GHCBS Gas Charbroilers SAVE THESE INSTRUCTIONS GENERAL Vulcan-Hart Gas Charbroilers feature heavy-duty, cast-iron burners; input rating is 16,000 Btu per burner. Each burner is controlled by an adjustable gas valve. Baffles suspended beneath the burners reflect the heat upward, maintaining a cool zone under the burner. Special cast-alloy radiants are located directly above each burner to maintain uniform temperature.
ACCESSORIES • Stainless steel splasher guard (HGB and HGBM only) • 12" work shelf (HGB and HGBM only) • Four swivel casters (HGB and GHCBS only) • Griddle plate 18" D x 133/4" W x 1/2" Thk.
Install the charbroiler in an area that has sufficient air supply for combustion of the gas at the burners. Provide adequate clearance for air openings into the combustion chamber. Do not obstruct the flow of combustion and ventilation air. Do not permit fans to blow directly at the charbroiler and, wherever possible, avoid open windows next to the sides or back. Avoid wall-type fans that create air cross currents within the room.
Battery Installation (GHCB Only) Since January 5, 1998, Vulcan-Hart appliances have changed from using Stockham gas unions to Ward (Fig. 1). If you are installing a new battery range to an existing field appliance, the union on the existing field appliance must be checked against the union being used on the new range. The union manufacturer's name around the face surface of the union nut must match. If the new range has been shipped using a Ward union and the old appliance has something different—i.e.
GAS CONNECTIONS CAUTION: All gas supply connections and any pipe joint compound must be resistant to the action of liquefied petroleum gases. The gas inlet is located at the middle rear (offset to right on HGB71). Codes require that a gas shutoff valve (not included) be installed in the gas line ahead of the charbroiler. The gas supply line must be 11/4" (32 mm) NPT (inside diameter). Make sure the pipes are clean and free of obstructions, dirt and piping compound.
GAS PRESSURES AND ORIFICES The standard orifices are set at 6" W.C. (Water Column) pressure for natural gas and 10" W.C. (Water Column) pressure for propane. TESTING THE GAS SUPPLY PIPING SYSTEM When test pressures exceed 1/2 psig (3.45 kPa), the charbroiler and an individual shutoff valve must be disconnected from the gas supply piping system. When test pressures are 1/2 psig (3.45 kPa) or less, the charbroiler must be isolated from the gas supply piping system by closing its individual shutoff valve.
OPERATION WARNING: HOT PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING THE BROILER. LIGHTING THE MANUAL GAS PILOT Adjustment of the pilot light must be performed by a qualified Vulcan-Hart installation or service person. The flame adjustment must be made at the time of installation. 1. Turn main gas supply ON. 2. Wait 30 seconds and, using a lighted taper, light the pilots. The pilot for each burner must be lit (Fig. 4). 3. If pilot fails to light, turn main gas supply OFF. Wait 5 minutes and repeat. Fig.
CONTROLS (FIG. 5) – HGB(M) BROILERS OFF — Horizontal when off. ON — Turn valve handle counterclockwise 90 degrees so it is vertical to open the burner gas valve completely. Adjust the valve between OFF and ON positions to moderate the heat. Fig. 5 CONTROLS (FIG. 6) – GHCBS BROILERS OFF — Turn the knob to the right. LO — Turn the knob to the left. HI — Turn the knob straight up to the 12-o'clock position.
CLEANING • Keep the broiler clean. • Clean the grate grooves with the wire brush provided. • Empty the grease drawer frequently. Top Grates Clean the top grates daily on both the top and bottom surfaces with a good wire brush or burlap or other grease-absorbing material to remove spillover, grease and so forth before it burns in. Avoid a crust on the top of the grill: It looks unsightly and slows cooking speed (scrape off if necessary). Burn off grates at full input after cleaning.
MAINTENANCE WARNING: HOT PARTS CAN CAUSE BURNS. USE CARE WHEN MAINTAINING THE BROILER. BURNERS If, after a period of satisfactory operation, burner flame characteristics should change or length of flame should be reduced, burner ports may have become restricted. Burners should be cleaned at least every 60 days and more often if required. To clean burners, remove and boil in a strong solution of lye water for about 15 minutes. Ports can be opened with a sharp-pointed instrument or proper-sized drill bit.
