FEATURES AND OPTIONS– 4 –

INSTALLATION Before installing, verify that the electrical service and type of gas supply (natural or L.P.) agree with the specications on the rating plate, located behind the top trim panel on the front of the oven. If the supply and equipment requirements do not agree, do not proceed with the installation. Contact your dealer or Vulcan-Hart Company immediately. UNPACKING This oven was 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 oven is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Carefully unpack the oven and place it in a work-accessible area near to its nal installed position. Do not use the doors or their handles to lift the oven. LOCATION The equipment area must be kept free and clear of combustible substances. When installed, minimum clearance from combustible construction must be 1 inch (25 mm) at the left side, 2 inches (51 mm) at the right side and 0 inch (0 mm) at the rear. Minimum clearance from noncombustible construction must be 0 inch (0 mm) at the left side, 0 inches (0 mm) at the right side and 0 inch (0 mm) at the rear. The oven may be installed on combustible oors. The installation location must allow adequate clearances for servicing and proper operation. For solid state and digital control models, there must be 18 inches (457 mm) of clearance on the right side of the oven from any open ame. The oven must be installed so that the ow of combustion and ventilation air will not be obstructed. Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is an adequate supply of air in the room to allow for combustion of gas at the oven burners. Do not permit fans to blow directly at the oven. Wherever possible, avoid open windows next to the oven. Avoid wall-type fans which create air cross currents within the room.

INSTALLING BASIC OVEN

The basic oven must be installed on legs or be mounted on a modular stand. Installations on concrete bases or other supports restricting air circulation underneath the oven is not advisable and may void the warranty. Ovens Mounted on Casters Ovens mounted on casters must use a exible connector (not supplied by Vulcan) 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 appliance without depending on the connector and the quick-disconnect device or its associated piping to limit appliance movement. Attach the restraining device at the rear of the oven as shown in Fig. 1. Remove two screws from the rear of the oven and install the tie-down strap shipped with the casters using these screws (Fig. 1). Attach the gas line strain relief to the tie-down strap at the rear of the oven (Fig. 1). If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect this restraint prior to turning the gas supply on and returning the oven to its installation position. Separate instructions for installing casters to the oven are included with the casters. Note: If the oven is installed on casters and is moved for any reason, it is recommended that the oven be releveled front to back and side to side. Fig. 1 CONNECT GAS LINE STRAIN RELIEF HERE PL-53563– 6 –

ASSEMBLING STACKED OVENS

Unpack the ovens and stack kit. Position the oven to be used as the bottom oven on its back for access to the oven bottom, taking care not to scratch or damage it. The gas pipe protrudes beyond the back; provide for this when the oven is tipped back by resting it on suitable spacers (2 x 4” [51 x 102 mm], etc.). Attach the four leg assemblies with the 24 bolts and lockwashers (six per leg). Place the lower oven (with legs) on the oor and remove two

/16 inch (11 mm) diameter knockouts on each side of the top cover. Remove vent guard and discard it. Move the oven with legs to the installed position and place upper oven on top of lower oven using the locating studs. Install the stacking ue (Fig. 3) with the four screws provided. Connect the piping between the top oven and bottom oven. For all gas supply connections, pipe joint compound must be resistant to the action of propane gases. LEVELING Make sure that the oven racks are level in the nal installed position. If the oven is installed on legs, turn the adjustable feet in or out to level the oven front-to-back and side-to-side. If the oven is installed on casters, loosen set screws and turn casters in or out to level the oven front-to-back and side-to-side. Retighten set screws after leveling. Assembling the Legs to the Oven The legs must be installed on the bottom of the oven. Gently position the oven on its side, taking care not to scratch or damage it. Attach each of the four leg assemblies to the bottom of the oven with the 24 bolts and lockwashers (six per leg). Carefully raise the oven to its normal position.

ASSEMBLING THE STAND TO THE OVEN

Attach each of the four leg assemblies to the bottom of the oven with the 24 bolts and lockwashers (six per leg). Carefully raise the oven to its normal position. Attach the undershelf to the legs with eight bolts and lockwashers (two per leg). Install the rack guides into the undershelf at desired locations (for pan or at rack), then attach the rack supports to the top end of the rack guides. Attach rack supports to the leg assembly by removing one middle bolt and reattaching back through the end holes in the rack support (Fig. 2). Fig. 2 Fig. 3 STACKING FLUEPL-53564 BACK FRONT

GAS CONNECTION Gas supply connections and any pipe joint compound must be resistant to the action of propane gases. Location of the gas inlet is at the rear of the oven. Codes require that a gas shutoff valve must be installed in the gas line ahead of the oven. Connect gas supply after leveling the oven. The gas supply line must be at least the equivalent of

/4 inch (19 mm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt or pipe joint compound. The ovens are equipped with xed burner orices which coincide with installation elevation. Standard oven with electronic ignition is provided with a regulator integral to the gas solenoid valve and requires no external regulator. Ovens with standing pilot must use external regulator provided with unit, set to pressures as indicated in above gas data chart. The gas pressure regulator provided with Standing Pilot must be used. This regulator is set for an outlet pressure of 3.7” W.C. (0.93 kPa) natural gas and 10” W.C. (2.5 kPa) propane gas. Prior to lighting, check all joints in the gas supply for leaks. Use soap and water solution. Do not use an open ame. A. Check all joints prior to the gas valve (solenoid) before lighting unit. B. Check all joints beyond gas valve (solenoid) after unit is lit. After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

TESTING THE GAS SUPPLY SYSTEM

When gas supply pressure exceeds

/2 psig (3.45 kPa), the oven and its individual shutoff valve must be disconnected from the gas supply piping system. When gas supply pressure is

/2 psig (3.45 kPa) or less, the oven should be isolated from the gas supply system by closing its individual manual shutoff valve.

BURNER AIR ADJUSTMENT

Although main burner air is adjusted before shipment, it should be checked at the time of installation. Excessive air will cause ames to lift off a burner when cold or may cause ash-back during normal cycling of oven, particularly when propane gas is used.

Natural (Propane) Natural (Propane) All models Standing Pilot MODEL GAS DATA– 8 – VENT SYSTEM DO NOT obstruct the ow of ue gases from the ue located on the rear of the oven. It is recommended that the ue gases be ventilated to the outside of the building through a ventilation system installed by qualied personnel. Ovens may use an optional down-draft diverter ue method. This optional down-draft diverter must be purchased from the oven manufacturer and vented to the outside; otherwise, the installation of any such device will void all oven certications and warranties. This oven is suitable for connection to Type B Gas Vent when used with the draft hood provided. From the termination of the ue to the lters of the hood venting system, a minimum clearance of 18 inches (457 mm) must be maintained. Information on the construction and installation of ventilating hoods may be obtained from Vapor Removal from Cooking Equipment, NFPA Standard No. 96 (latest edition), available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269. ELECTRICAL CONNECTIONS Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes. Appliances equipped with a exible electric supply cord are provided with a three- prong grounding plug. It is imperative that this plug be connected into a properly grounded three- prong receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove the grounding prong from this plug. VC series ovens with 120 V/60 Hz/1 PH electrical specication are equipped with a cord and plug as standard equipment. A wiring diagram is located on the inside of the control housing. Insufcient air will cause ames to burn with a yellow tip and result in carbon accumulation in the ame chamber and heat exchanger tubes. Contact your local Vulcan-Hart servicer if required.

CONSERVING ENERGY— ALL MODELS

• Turn off unused equipment.

• Adjust menu patterns and cooking/baking schedules for optimum equipment use.

• Reduce thermostat settings in slack periods since gas equipment heats up and recovers quickly.

• Preheat only to required cooking temperature for specic food — not higher.

• Do not open the oven door unless absolutely necessary.

• Keep area around the oven door clean and free of food particles.

• Any obstruction that prevents the door from closing completely will adversely affect oven efciency.– 14 – PROGRAMMABLE CONTROLS

Meat roasting is most satisfactory at temperatures of 225 to 325°F (107 to 163°C) for beef, lamb, poultry and ham; 325°F (163°C) for fresh pork as recommended by USDA and American Meat Institute. A pan, approximately 12 x 20 x 1” (305 x 508 x 25 mm) full of water, may be placed in the oven bottom. This water supplies humidity to reduce shrinkage. Water should be added if necessary during roasting. Roasting pans should be no deeper than necessary to hold drippings (usually 2 to 2

/2” (51 to 64 mm). Cooking time and shrinkage may vary with roasting temperature, cut, grade of meat and degree of doneness. Smaller cuts will generally show greater time savings than larger cuts at a given temperature.

Meat Loaf — 8 to 10 lb (3.6 to 4.5 kg) 350 (177) 45 to 60 Minutes COOKING HINTS Forced air convection cooking is faster than conventional oven cooking, and therefore overcooking is more common. Do not cook products faster than is practical for the best results. Since forced air convection supplies heat to the surface of the product, the thicker or more massive a product is for its type, the longer it will take to absorb enough heat to cook. The oven will cook or bake full or partial loads at standard recipe temperatures. As with any oven, you may wish to use a temperature of up to 25 F° (-4 C°) higher or lower than the recipe for the particular product result that you prefer. When established, convection oven times and control settings should be noted on your recipe.

SUGGESTED COOKING GUIDELINES

Recommended temperatures, times and number of racks are intended as a guide only. Adjustments must be made to compensate for variations in recipes, ingredients, preparation and personal preference in product appearance. The oven does not require special recipes. Excellent results can be obtained from any good commercial recipe with reduced cooking times.– 16 – RECOMMENDED TEMPERATURES, TIMES AND NUMBER OF RACKS FOR BAKING

Snorkel The snorkel (heat circulation tube), located in the back of oven cavity, should never be blocked. The snorkel should be kept clean at all times for proper operation of the oven. Clean with standard oven cleaner at least once a week. Be sure to thoroughly clean all cleansing solution off before using the oven again. It is also recommended that the oven be run at 400°F (204°C) for 20 minutes before using to burn off any cleaning solution that was not thoroughly rinsed from the snorkel. Daily Exterior stainless steel oven panels should be cleaned with a damp cloth. Stubborn soil may be removed with detergent. (DO NOT USE DAWN

.) Rinse thoroughly and wipe dry with a soft, clean cloth. Clean porcelain oven interior daily with soap or detergent and water. Rinse thoroughly and wipe dry with a soft, clean cloth. Nickel-plated racks and rack supports are dishwasher-safe and may be removed for cleaning. For exterior burned-on foods and grease which resist simple soap and water cleaning, an abrasive cleanser (scouring powder) mixed into a paste may be used. Apply with stainless steel wool or sponge, always rubbing with the “grain.” This treatment is equally effective for “heat tint” (slightly darkened areas caused by oxidation). Again, remember to rub in the direction of the polish lines. Rinse with clear water and dry with a soft cloth. Do not use scouring powder on the glass window; it will scratch and fog the glass. After processing some foods at low temperatures, odors may linger in the oven. These odors may be cleared by setting the thermostat to 500°F (260°C) and allowing the oven to run unloaded for 30 to 45 minutes.

GUIDELINES FOR MAINTAINING STAINLESS STEEL SURFACES

There are three basic things that can break down the surface layer of stainless steel and allow corrosion to develop: 1) Abrasion; 2) Deposits and water and 3) Chlorides. Avoid abrasion from rubbing with steel pads, wire brushes or scrapers that can leave iron deposits on stainless steel; instead, use plastic scouring pads or soft cloths. For stubborn stains, use products such as Cameo, Talc or Zud First Impression. Always rub parallel to the polish lines or with the grain. Hard water can leave deposits that promote rust on stainless steel. Treated water from softeners or certain lters can eliminate these mineral deposits. Deposits from food must be properly removed by cleaning. Use mild detergent and nonchloride cleaners. Rinse thoroughly. Wipe dry. If using chloride-containing cleaners or sanitizers, rinse repeatedly to avoid stainless steel corrosion. Where appropriate, apply a polish recommended for stainless steel (such as Benet or Super Sheen) for extra protection and lustre.– 19 – MAINTENANCE The oven and its parts are hot. Use care when operating, cleaning or servicing the oven. Disconnect the electrical power to the machine and follow lockout / tagout procedures. LUBRICATION The fan motor comes with sealed bearings and requires no lubrication. VENT Periodically check the ue, when the oven is cool, to be sure it is free of obstructions. REPLACING LAMPS

1. Allow oven to cool.

2. Remove all racks by pulling forward, lifting up and out.

3. Unscrew glass dome from light body.

4. Replace the bulb.

5. Reassemble glass dome and racks.– 20 –
