INSTALLATION

Before installing, verify that the electrical service and type of gas supply (natural or L. P. gases) agree
with the specifications 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 Wolf Range immediately.

UNPACKING

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 in a work-accessible area near to its final 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, 4 inches (102 mm) at the right side and 6 inches
noncombustible construction must be 0 inch (0 cm) at the left side, 4 inches (102 mm) at the right side
and 6 inches (152 mm) at the rear. The oven may be installed on combustible floors.

The installation location must allow adequate clearances for servicing and proper operation. There
must be 18 inches (457 mm) of clearance on the right side of the oven from any open flame.

The oven must be installed so that the flow 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

CONNECT

GAS LINE

STRAIN RELIEF

HERE

PL-53563

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 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 quick­disconnect device that complies with the Standard for Quick­Disconnect 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 quick­disconnect 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 tie­down strap shipped with the casters using these screws (Fig. 1).

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.

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 THE STAND TO THE OVEN

Attach each of the four leg assemblies to the bottom of the oven with the

FRONT

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).

RACK SUPPORT

Install the rack guides into the undershelf at desired locations (for pan or
flat rack), then attach the rack supports to the top end of the rack guides.

RACK GUIDE

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).

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

3

/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.
