If a power supply cord is being used, the cord must be
designated for use with ranges and rated for 240 V, 30 or
50 amps (refer to the chart below), and must include 3 or 4
conductors. A 4-conductor cord is required for installations
where grounding through the neutral is prohibited.
Performance may be compromised if the electrical supply is
less than 240 volts.

(LP) gas. It is design certied by the Canadian Standards
Association (CSA) for natural or LP gases. The product
rating plate has information on the type of gas that should
be used. For rating plate location, refer to the illustration on
page 3. If this information does not agree with the type of
gas available, check with the local gas supplier.

Preparation
Before moving the range, protect any nished ooring and
secure oven door(s) closed to prevent damage.
To lighten the load or to t through a door way, the oven
door(s) can be removed. Only remove if necessary. Do not
remove griddle or any other component. Door removal
should only be done by a certied installer or service
technician.
For removal, a hinge pin will be inserted into the appropriate
hinge shown in the illustrations below. The pin(s) are located
inside the oven door. For single oven ranges, the hinge pin
must be inserted in the right hinge. For double oven ranges,
the pins must be placed in the outer two hinges.
CAUTION
Failure to insert the hinge pin in the appropriate hinge
arm will cause damage to the range.
INSTALLATION
OVEN DOOR REMOVAL
1Insert the hinge pin into the appropriate hinge.
2Remove the lower kickplate assembly to access the
lower hinge retainer mounting screws.
3Open the oven door and remove both upper and lower
hinge retainer mounting screws. The oven gasket may
have to be moved slightly to access the bottom screws.
4Move the hinge retainer plate forward slightly. The hinge
retainer plate will remain on the door hinge after the
mounting screws have been removed.
5Carefully close the oven door to approximately 60°, then
lift the door up and out. A slight rocking motion may be
required for removal.

INSTALLATION
Placement
Do not lift or carry the oven door by the door handle. The
range has rear casters which allow for easy movement by
lifting the front of the unit.
Use an appliance dolly to move the unit near the opening.
Remove and recycle packing materials. Do not discard the
anti-tip bracket supplied with the range.
If a riser has been specied, refer to the installation instruc-
tions packaged with the riser. The riser must be installed
before the range is installed.
Anti-Tip Bracket
Raise the unit to its desired height by adjusting the front
legs and rear casters. Use a 3/4" socket to adjust the rear
casters. The front legs can be adjusted by rotating the hex-
agonal leg clockwise to raise and counterclockwise to lower.
To ensure the anti-tip bolt engages the bracket, refer to the
chart and illustration below to determine proper placement.

Anti-Tip Bracket
INSTALL BRACKET
Drywall application |After properly positioning the anti-tip
bracket, mark holes, then use a Philips screwdriver or a low
rpm power drill to drive the wall anchor into the surface of
the wallboard until ush. Pre-drill holes if needed. For hard
wallboard or double-board construction, use a 1/4" drill bit.
For solid plaster, use a 7/16" drill bit. Refer to the illustration
below. Use #8 screws and at washers to fasten the bracket
to the wall.
Wood oor application |After properly positioning the
anti-tip bracket, drill 3/16"(5) pilot holes through the oor.
Use #12 screws and at washers to secure the bracket to
the oor.
Concrete oor application |After properly positioning
the anti-tip bracket drill 3/8"(10) holes into the concrete a
minimum of 11/2"(38) deep. Use 3/8" wedge anchors to
secure the bracket to the oor.
ANTI-TIP BOLT ADJUSTMENT
Once the bracket is secure, adjust the anti-tip bolt so the
top of the washer is 7/8"(22) maximum from the oor. Slide
the range into the opening and verify the anti-tip bolt is
engaged. Refer to the illustrations below.

Electrical Connection
The terminal block on the back of the range allows for a
3-wire or 4-wire installation. For a 4-wire installation, the
ground strap from the unit to the terminal block must be cut.
Two concentric knockouts are provided to allow for perma-
nent or cordset wiring of the unit.
THREE-WIRE ELECTRICAL SYSTEM
1Where local codes permit, connect the ground appliance
wire to the neutral (white) supply wire.
2Connect the ground and white appliance wires to the
neutral (white) supply wire in the electrical box.
3Connect the black appliance wire to the black (L1) power
supply wire in the electrical box.
4Connect the red appliance wire to the red (L2) power
supply wire in the electrical box.
FOUR-WIRE ELECTRICAL SYSTEM
1Separate the ground and white appliance wires.
2Connect the white appliance wire to the neutral (white)
supply wire in the electrical box.
3Connect the black appliance wire to the black (L1) power
supply wire in the electrical box.
4Connect the red appliance wire to the red (L2) power
supply wire in the electrical box.
5Connect the ground appliance wire to the green/ground
house grounding wire in the electrical box.
INSTALLATION
Gas Supply Connection
All connections to the gas piping must be wrench-tightened.
Do not overtighten or allow pipes to turn when tightening.
If a exible metal connector is being used, verify it is not
kinked, then attach the gas supply line to the regulator on
the range. Open the valve and check for leaks by placing a
liquid detergent solution onto all gas connections. Bubbles
around connections indicate a gas leak. If a leak appears,
close the shut-off valve and adjust connections.

Troubleshooting
IMPORTANT NOTE: If the range does not operate properly,
follow these troubleshooting steps:
•Verify electrical power is supplied to the range.
•Verify the gas supply shut-off valve is in the open
position.
•If the range does not operate properly, contact Wolf
factory certied service. Do not attempt to repair the
range. Wolf is not responsible for service required to
correct a faulty installation.
