LEG/CASTER ASSEMBLY

The range is shipped fully assembled, except for the legs. The range is provided with 6″(152 mm) adjustable stainless steel legs (hardware included), packaged in a box located inside of the oven. A set of 6″(152 mm) casters are available as an optional field installable accessory.

Installation of Legs/Casters:

1. Carefully tip range on its side.
2. Align holes in leg/caster mounting plate with pre-drilled holes in bottom of range located in each of the four corners. Two additional legs/casters must be installed on the C48, C60, and C72. The additional legs/casters should be installed utilizing the pre-drilled holes shown in Figure 1.
3. Attach mounting plate to bottom of range using four ¼ – 20 x ⅝“ self tapping screws (provided). If casters are being installed, the locking casters should be mounted on the front.
4. After all legs/casters have been installed, carefully return the range to its upright position.

(For additional leg information, see Leveling section of this manual).
Ranges mounted on casters must use a flexible connector (not supplied by Wolf) 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 range.
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 range to its installation position.
If the range is installed on casters and is moved for any reason, it is recommended that the range be re-leveled front to back and side to side for even baking.

LEVELING

To level the range, place a carpenter’s level on the range top and check leveling of the unit side to side and front to rear. Achieve leveling by turning each foot section of the unit’s leg as needed. Turning the foot in a counter clockwise direction will increase height and clockwise will decrease.

GAS PRESSURE REGULATOR

A preset gas pressure regulator and street elbow is shipped with the range. This regulator must be installed by an authorized service person before the unit is placed into operation. See full unit data plate located on the rear of the range, or the secondary data plate, riveted to the kick panel, for pressure regulator setting information. If a manometer is being used, utilizing one of the available pressure taps in the manifold, the manifold pressure with one burner on should be ± 0.3″ W.C. of the value indicated on the rating plate.

1. Locate the gas connection pipe protruding through the back of the unit.
2. Cover the pipe threads with pipe joint compound resistant to propane gases.
3. Screw the regulator onto the pipe hand tight with flow direction arrow pointing towards the back of the unit and the regulator adjustment in the up right position.
4. With a pipe wrench, tighten the regulator securely in the upright position. (The regulator is preset and should not require any additional adjustments.) The pressure regulator must be mounted horizontally to ensure the proper preset outlet pressure. If  mounted in any other direction, the outlet pressure must be rechecked and possibly reset. A leak limiter is supplied with every regulator to allow excess gas pressure to escape. Do not obstruct the limiter or the gas regulator, as obstruction may cause the regulator to malfunction.

GAS CONNECTIONS

NOTICE
All gas supply connections and any pipe joint compound used must be resistant to the action of propane gases.
WARNING
Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution. Do not use an open flame.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When test pressures exceed ½ psig (3.45 kPa), the range 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 range must be isolated from the gas supply system by closing its individual manual shutoff valve.
FLUE CONNECTIONS
DO NOT obstruct the flow of flue gases from the flue located on the rear of the range. Proper venting of flue gas is vital to the safe and efficient operation of the range. Problems arising from the intentional obstruction of the flue will result in voiding of warranty. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel. From the termination of the flue to the filters of the hood venting system, a minimum clearance of 18″ (457 mm) must be maintained. Information on the construction and installation of ventilating hoods may be obtained from the standard for “Vapor Removal from Cooking Equipment,” NFPA No. 96 (latest edition), available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
ELECTRICAL CONNECTIONS
WARNING
Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes.
WARNING
Disconnect the electrical power to the machine and follow Lockout / Tagout procedures.
WARNING
Appliances equipped with a flexible electrical 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.
The convection range is designed for 120 volt power supply and is provided with a flexible electric supply cord and plug that must be plugged into the proper receptacle. Do not connect the convection range to electrical supply until after gas connections have been made. The wiring diagram for the convection range is located on the rear of the appliance.

OPERATION

WARNING
The appliance and its parts are hot. Use care when operating, cleaning, or servicing the appliance.
CONTROLS
Open Top Burner Valve — Allows gas to flow to the top burners. To open valve, turn knob counterclockwise. To close valve, turn knob clockwise.
Manual Griddle Valve — Allows gas to flow to the griddle burners. To open valve, turn knob counterclockwise. To close valve, turn knob clockwise.
Oven Thermostat — Regulates oven temperature. The thermostat temperature range is from LOW at approximately 250°F (121°C) to HI at approximately 500°F (260°C). Turn the thermostat counterclockwise to increase temperature and clockwise to decrease temperature. Oven temperature regulation is the most accurate between 300°F (149°C) and 500°F (260°C).
Griddle Thermostat — Regulates griddle temperature. The thermostat temperature range is from LOW at approximately 200°F (93°C) to HI at approximately 550°F (288°C). Turn the thermostat clockwise to increase temperature and counterclockwise to decrease temperature.
Safety Valve – Monitors standing pilot. The oven and thermostatic griddle feature a standing pilot that must be manually lit. The pilot is monitored by a thermocouple and pilot safety valve. If the pilot goes out, the safety valve will shut-off the gas supply to the pilot and main burners.
Fan Switch – Turns fan on and off (Convection Ovens only). Fan turns on when door is closed. Fan turns off when door is opened.
BEFORE FIRST USE
Ovens
New ovens require a burn off period to break in the oven and eliminate unappetizing odors from penetrating the food product. These odors are typically from curing of the porcelain enamel oven cavity parts.
Turn on gas to unit and set the thermostat to 475°F (246°C). Allow the oven to operate at this temperature for 30 to 45 minutes.
Griddles
Before leaving the factory the griddle is coated with vegetable oil as a rust inhibitor. Remove this film when the griddle plate is being cleaned prior to its first cooking use. Heat the griddle to 200-300°F to loosen and melt the coating, then clean the surface with a non-corrosive, grease dissolving commercial cleaner, following the manufacturer’s directions. Rinse thoroughly and wipe dry with a soft clean cloth. Clean all accessories.
NOTICE
The griddle plate is steel, but the surface is soft and can be scored or dented by careless use of spatulas or scrappers. Be careful not to dent, scratch or gouge the plate. Do not try to knock off loose food that may be on the spatula by tapping the corner edge of the
spatula on the griddle surface.
Season the griddle to avoid possible surface corrosion before first use, and after every cleaning. Heat griddle to a low temperature (300-350°F) and apply a small amount of cooking oil – about one ounce per square foot of surface. Use a soft lint-free cloth to spread the oil over the entire griddle surface to create a thin film. Wipe off any excess oil with a cloth. Repeat the procedure until the griddle has a slick, mirror-like finish.

OPERATING SUGGESTIONS

Open-Top Burners
Open-top burners are quickly lit and require no preheating time. Open top burners have a wide low to high burner flame adjustment range. This allows for better simmering performance at the lowest possible stabilized setting. When simmering, turn the burner valve knob down until you reach the optimum lowest burner flame setting to maintain the desired simmer point.
Manual Griddle
Pre-heat the griddle top for approximately 15 – 20 minutes before cooking. The top can be kept hot with burners turned partially down. During off periods, turn the burners down or heat only half of the top.
Thermostatic Griddle
Pre-heat the griddle top for approximately 15 – 20 minutes before cooking. The griddle thermostats regulate temperatures for each 12″ section of the griddle from a low setting at approximately 200°F (93°C) to high setting at approximately 550°F (288°C).
Standard Oven Cooking
Allow time to preheat ovens before using (25 minutes to 400°F [204°C]). The oven thermostat regulates temperature from a low setting at approximately 250°F (121°C) to high setting at approximately 500°F (260°C). If properly used, the automatic temperature control is an efficient system. Turn thermostat down to LOW when oven is idling, or turn the oven control to OFF when not in use.
Moderate oven temperatures will produce better food, reduce shrinkage and keep maintenance costs down. Using a low temperature for roasting (recommended 325°F [162°C] or lower) will reduce meat costs by reducing shrinkage.
A pan of water (approximately 12″ x 20″ x 1″ [305 mm x 508 mm x 25.4 mm]) may be placed in the oven bottom. This water supplies humidity to reduce shrinkage. If necessary, add water during roasting.
Convection Oven Cooking
Cooking time and temperature in convection oven may vary slightly from normal time and temperature.
LOADING AND UNLOADING THE OVEN
Open the door and load the oven as quickly as practical to conserve heat. Take care to avoid spilling liquids while loading. Close the door and refer to recipe for cooking time.
Provide adequate space for product unloading. Rapid unloading will conserve heat and ensure proper  reheating conditions for the next load, if applicable.
CLEANING
WARNING
Disconnect the electrical power to the machine and follow Lockout / Tagout procedures.
WARNING
Shut off the gas before cleaning the appliance.
WARNING
The appliance and its parts are hot. Be very careful when operating, cleaning, or servicing the appliance.
Exterior surfaces may be cleaned using soft cloth and mild detergent. Do not use Dawn® dish detergent to clean the exterior or interior components of the range.
Do not use scouring powder. It is extremely difficult to remove completely. It can build up accumulations that will damage the oven.
Wolf equipment is strongly constructed and is designed to give you long, satisfactory service at low cost, provided you give it proper care. Frequent cleaning and occasional adjusting should reward you with low operating and maintenance costs and faster, better service.
DAILY CLEANING
Oven
Remove chrome-plated racks and clean in a sink.
While still warm, wipe top with a soft cloth or other grease absorbing material to remove spillovers, grease, etc., before they burn in.
Clean oven and oven door daily, especially if fruit pies or tomato sauces were baked, meats roasted, and if there have been spillovers.
After processing some foods at low temperatures, odors may linger in the oven. These odors may be cleared by setting the thermostat at 500°F (260°C) and allowing the oven to operate unloaded for 30 to 45 minutes.
Open Top
Clean cast iron open top grates with a mild soap and water solution. Rinse thoroughly and dry with a clean, water-absorbent towel. Immediately after drying (with grates still removed from the range top), season grates lightly with liquid vegetable or spray-type cooking oil.
After seasoning, replace grates onto the range. Turn on all open top sections to LOW and allow them to burn for at least 15 minutes before using pots or pans on the range top. Season the open top grates after each cleaning. Failure to season grates will cause grates to rust.
Griddle Top
Empty the grease drawer as needed throughout the day and regularly clean at least once daily.
Clean the griddle regularly. A clean griddle always looks better, lasts longer and performs better. To produce evenly cooked, perfectly browned griddle products keep the griddle plate clean and free of carbonized grease. Carbonized grease on the surface hinders the transfer of heat from the griddle surface to the food, resulting in spotty browning and loss of cooking efficiency. Carbonized grease tends to cling to griddle foods, giving them a highly unsatisfactory and unappetizing appearance.
After each use, clean the griddle with a Scotch Bright pad or flexible spatula.
Once a day, thoroughly clean the griddle back splash, sides and front. Remove, empty and wash the grease drawer in the same manner as an ordinary cooking utensil.

EXTERIOR CLEANING
Daily
Clean exterior finish with a mild solution of soap or grease-dissolving cleaner. To remove discoloration, use a nonabrasive cleaner. Always rub with the grain of the metal. Stainless steel areas of the range can be polished by using a soft dry cloth. If needed, add stainless steel polish to the soft cloth.
STAINLESS STEEL
Here are a few simple cleaning procedures that have been found effective for keeping stainless steel equipment clean, sparkling and bright.
General Cleaning
Use ordinary soap or detergent and water for routine cleaning of stainless steel. To prevent water spots and streaks, rinse thoroughly with warm water and wipe dry with a soft clean cloth. The addition of a rinsing agent will also help prevent spotting. Do not pressure wash any portion of the range.
Fingerprints
Fingerprints are sometimes a problem on highly polished surfaces of stainless steel. They can be minimized by applying a cleaner that will leave a thin oily or waxy film. To use these cleaners, simply wipe on and remove excess with a soft dry cloth. After using, subsequent fingerprints will usually disappear when wiped lightly with a soft cloth or with a cloth containing a little of the cleaner. If the surface is especially dirty to start, wash first with soap or detergent and water.
Heat Tint
Straw-colored or slightly darkened areas may appear on stainless steel in and around ovens and ranges where temperatures reach 500°F (260°C) or more. This “heat tint” is caused by a slight oxidation of the stainless steel and is not harmful. To control or minimize this condition, never use more heat than is absolutely necessary.

MAINTENANCE & ADJUSTMENTS

WARNING
Disconnect the electrical power to the machine and follow Lockout / Tagout procedures.
LUBRICATION
All moving parts must be checked for wear and lubricated. Contact your local authorized servicer.
Motors in Wolf convection ranges are permanently lubricated and require no additional maintenance.
FLUE
Check the flue when it is cool to be sure it is free of obstructions.
SERVICE AND PARTS INFORMATION
To obtain service and parts information, contact an authorized service agency in your area (refer to our website, www.wolfrange.com for a complete listing of authorized service and parts depots). When calling for service, the following information must be available: model number, serial number, and gas type. This information can be found on the main data plate, located on the rear of the unit, or on the secondary plate located inside the lower front kick panel. Lift up and lower the front kick panel to view the secondary data plate.
PRECAUTIONS
When scraping off heavy deposits of grease or oil from stainless steel equipment, never use ordinary steel scrapers. Particles of ordinary steel may become embedded in, or lodge on, the surface of the stainless steel. These will rust, causing unsightly stains and possible contamination of food. If it is necessary to scrape, use stainless steel, wood, plastic or rubber tools.
