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.

Assembling the Legs to the Oven

The legs must be installed on the bottom of the oven. Gently position the

BACK

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 STACKED OVENS (OPTIONAL)

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's, etc.). Attach the four leg assemblies with the 24 bolts and lockwashers (six per leg).

Place the lower oven (with legs) on the floor 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 flue (Fig. 3) with the four screws provided.

STACKING FLUE

Connect the piping between the top oven and bottom oven. For all gas supply connections, pipe joint compound

PL-53564

must be resistant to the action of propane gases.

Fig. 3

LEVELING

Make sure that the oven racks are level in the final 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.

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 fixed burner orifices which coincide with installation elevation.

The oven is provided with a regulator integral to the gas solenoid valve and requires no external regulator.

Natural gas pressure regulators are preset for 3.5 inches W.C. (Water Column) (0.9 kPa); propane gas pressure regulators are preset for 10 inches W.C. (2.5 kPa).

Prior to lighting, check all joints in the gas supply for leaks. Use soap and

water solution. Do not use an open flame.

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.

– 6 –

Page 7

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 flames to lift off a burner when cold or may cause flash-back during normal cycling of oven, particularly when propane gas is used.

Insufficient air will cause flames to burn with a yellow tip and result in carbon accumulation in the flame chamber and heat exchanger tubes.

Contact your local Wolf Range servicer if required.

VENT SYSTEM

DO NOT obstruct the flow of flue gases from the flue located on the rear of the oven. It is recommended

that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

Ovens may use an optional down draft diverter flue 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 certifications and warranties. When the diverter is supplied, it may be connected to a Type “B” vent.

From the termination of the flue to the filters of the hood venting system, a minimum clearance of 18 inches (457 mm) should be maintained.

Information on the construction and installation of ventilating hoods may be obtained from

ROAST & HOLD OPERATION — (When Equipped)

Roast & Hold cooks the product in two stages. During first-stage cooking, the oven temperature is regulated by the temperature setpoint and the R & H Time setting. After the time counts down to 00:00, second-stage cooking begins. During second-stage cooking, the heating elements are off as the temperature in the oven declines to the hold temperature. The doors should remain closed during second-stage cooking.

When the hold temperature is reached, the display flashes HOLD. Temperature in the oven will be maintained at the hold temperature until the oven is turned off.

PROPER UTENSILS

The use of proper utensils can enhance oven operation. Medium and lightweight pans allow the product to warm faster. Roast meats in shallow pans deep enough to hold all juices yet allow free air circulation.

OPERATING HINTS

When using the convection oven for the first time with a particular food, check the degree of doneness periodically before the suggested time has elapsed. This will ensure the desired doneness is achieved.

Record your temperature and time settings for various products. The convection oven can provide consistent and repeatable results.

The convection oven is faster than conventional deck-type ovens; temperature settings are lower and cook times are shorter. Since recipes and foods are subject to many variations and tastes, the guidelines regarding Times and Temperatures in this manual are SUGGESTIONS ONLY. Experiment with your food products to determine the cooking temperatures and times that give you the best results.

RACK ARRANGEMENTS

PL-52806

RACK POSITION

#10

#11

All models are supplied with five racks and have a maximum operating capacity of six racks per oven. The 11-position rack supports provide for maximum flexibility and proper rack spacing.

The following arrangements are recommended. The position numbers are in numerical sequence starting at the bottom (Fig. 4).

Arrangement #1 — Five racks in positions #2, #4, #6, #8 and #10 for cookies or reconstitution of frozen lunches at maximum capacity. These are also the recommended positions for general baking in sheet pans with products not over 2

/2 inches (64 mm) high.

Arrangement #2 — Four racks in positions #1, #4, #7 and #10 are for general baking in sheet pans, muffin pans, pie or cake tins and pudding pans 3

/2 inches (89 mm) high with products not over 4 inches (102 mm) high. This arrangement can also be used for casseroles or meat dishes in #200 series food service pans 12 x 20 x 2 64 mm).

/2" (305 x 508 x

Fig. 4

Arrangement #3 — Three racks in positions #1, #5 and #9 are for baking breads or cakes in loaf or tube pans and high meringue pies. This arrangement can also be used for casseroles, meat dishes or cooking in pans up to 5

2 inches (140 mm) deep with products up to 6 inches (152 mm) high.

Arrangement #4 — Two racks in positions #1 and #6 are for cooking turkeys and other roasts up to 7 inches (178 mm) high.

With the rack in position #1, there is limited space for a water pan (see cooking chart in this manual).

When mixed loads or partial loading is regular practice, some users have developed other rack arrangements to suit their particular needs.

SPECIAL PROCEDURES FOR BAKING

Yeast Bread: Cooking starts immediately in the convection oven. Yeast breads do not usually rise as much in a convection oven as in a conventional oven. Therefore it is usually necessary to allow fuller proof, 2

/2 to 3 times increase in volume, for best results.

Pies: When baking pies in your convection oven, three or four pies should be put on an 18 x 26" sheet or bun pan. This procedure helps the bottom crust to bake, makes handling easier and reduces the possibility of boilover spoiling the appearance of the pies on the lower racks.

HIGH LIMIT SWITCH

All ovens are equipped with a high limit switch, which senses the temperature of the oven to prevent overheating. The high limit switch operates independently and will automatically shut the oven down should the primary control fail. If this situation occurs, DO NOT attempt to bypass the high limit. Shut the oven down and contact your local Wolf Range authorized service agency.

Page 15

RECOMMENDED TEMPERATURES AND TIMES FOR ROASTING

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.

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.

Once established, convection oven time and temperature 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.

CLEANING

Disconnect the electrical power to the machine and follow lockout / tagout

procedures.

Allow the oven to cool before cleaning.

Heat Circulation Tube

The heat circulation tube, located in the back of the oven cavity, should never be blocked. The heat circulation tube 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 heat circulation tube.

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 temperature 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 filters 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 Benefit or Super Sheen) for extra protection and lustre.

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 flue, when the oven is cool, to be sure it is free of obstructions.

REPLACING LAMPS

• Allow oven to cool.

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

• Unscrew glass dome from light body.

• Replace the bulb.

• Reassemble glass dome and racks.
