C72 6 6

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.

Figure 1 - Cross Chassis Leg/Caster Mounting

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.

- 5 -

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

All gas supply connections and any pipe joint compound used must be resistant to the action

of propane gases.

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.

- 6 -

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

Electrical and grounding connections must comply with the applicable portions

of the National Electrical Code and/or other local electrical codes.

Disconnect the electrical power to the machine and follow Lockout / Tagout

procedures.

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

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).

- 7 -

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.

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.

LIGHTING AND SHUTTING DOWN PILOTS
